  • Coastal Low Brings Chilly, Showery Weekend to Delmarva

    Coastal Low Brings Chilly, Showery Weekend to Delmarva

    A pair of low pressure systems will impact the Delmarva region from Friday night through the weekend, bringing periods of light rain, gusty onshore flow, and a return to below-average temperatures.

    The first system, a weak area of low pressure, is expected to pass through the region Friday night. This will deliver a quick shot of light precipitation, with most areas seeing minimal rainfall totals. Impacts from this initial system appear limited, but it sets the stage for a more complex setup heading into Saturday.

    Attention then turns to a stronger system developing to the south. A deep upper-level trough digging across the Midwest and Gulf Coast states will help spawn a more organized area of low pressure over the southeastern United States. This system is forecast to lift north toward the Mid-Atlantic during the day Saturday before tracking offshore by Saturday night into Sunday.

    For Delmarva, this track is critical. Current trends suggest the heaviest rainfall will remain offshore, particularly east of the coastline. However, wraparound moisture on the backside of the system will likely spread clouds and occasional rain back into the region, especially across Delaware and far southeastern New Jersey where rain chances are highest.

    While this will not be a washout for most, periods of light rain and persistent cloud cover are expected through at least part of the weekend. The combination of onshore flow and thick cloud cover will also keep temperatures suppressed, with highs generally stuck in the 50s to low 60s, well below late-April normals.

    Overall, the weekend will feature more clouds than sun, with occasional showers and a cool, damp feel. While beneficial rainfall is possible in spots, the bulk of the system’s moisture is expected to remain just offshore, limiting more widespread or heavier totals across the region.

  • DEMA Mobilizes Delaware National Guard in Preparation for Coastal Storm Effects

    DEMA Mobilizes Delaware National Guard in Preparation for Coastal Storm Effects

    (SMYRNA, DE) — The Delaware Emergency Management Agency (DEMA) has announced the activation of the Delaware National Guard to support preparations and response efforts as the state faces threats from coastal flooding and strong winds expected to persist through tomorrow.

    Having coordinated with state and local officials since Friday, DEMA said it is strategically deploying Guard resources to where they will be needed most. Reception centers are already open across Kent and Sussex counties, with sheltering plans in place should demand increase. Agencies including the Delaware Department of Health and Social Services, DelDOT, and the American Red Cross are working closely with local authorities to facilitate access to these resources.

    In Bowers Beach, the mayor has issued a voluntary evacuation order for residents east of Whitwells Delight Road. Individuals needing shelter are guided to the Magnolia Fire Company or to contact the Kent County Emergency Operations Center at 302-735-3465 for further guidance.

    Reception Center Locations

    • Kent County: Magnolia Fire Hall, 2 North Main Street, Magnolia, DE
    • Sussex County: Millsboro Fire Hall, 109 E State St, Millsboro, DE

    DelDOT continues to monitor road conditions and post closures through its website and mobile app. Meanwhile, DNREC has closed beaches, surf crossings, and campgrounds at Delaware Seashore State Park and Cape Henlopen State Park until further notice.

    DEMA Director A.J. Schall commented, “We’re monitoring the situation and proactively positioning additional resources to support counties and municipalities in safeguarding residents. DEMA will continue to issue Watches, Warnings, and other directives as needed.”

    Officials warn that moderate-to-major coastal flooding, damaging wind gusts, tree damage, power outages, and roadway flooding remain possible. Additional local evacuations may be ordered if conditions worsen.

    Safety Guidelines for Residents

    1. Enroll in DENS – Sign up for the Delaware Emergency Notification System to receive alerts via phone or email.
    2. Know your zone – Use the Know Your Zone tool to determine whether your address falls within an evacuation zone. Stay alert even if you are outside a designated zone.
    3. Plan your evacuation – Outline a route, inform family members, and carry hard copies of important documents.
    4. Assemble an emergency kit – Include essentials such as medications, food, water, batteries, flashlights, and supplies for pets for 3–7 days.
    5. Stay informed – Monitor trusted media, state agencies’ social accounts, and radio stations for updates.
    6. Turn Around, Don’t Drown – Never drive through floodwaters.

    Emergency Alert Radio Stations: WDEL-AM 1150, WDEL-FM 101.7, WCHK-FM 101.3, WWTX-AM 1290, WRDX-FM 92.9, WJWL-AM 900, WDOV-AM 1410, WSTW-FM 93.7, WDDE-FM 91.1, WILM-AM 1450, WDSD-FM 94.7. Boaters should monitor Marine Channel 16

  • Strong Coastal Low Could Bring Major Impacts to Delmarva This Weekend

    Strong Coastal Low Could Bring Major Impacts to Delmarva This Weekend

    A powerful coastal low is forecast to develop off the Carolina coast late this week before strengthening and tracking northward this weekend. The system is expected to bring gusty winds, heavy rain, and coastal flooding to much of the East Coast — including the Delmarva Peninsula.

    The combination of strong onshore winds, high surf, and high astronomical tides could lead to significant coastal flooding across parts of Delaware, Maryland, and Virginia. The most widespread impacts are expected from Friday night through Sunday, with the highest risk during periods of high tide.

    Persistent onshore winds will also generate dangerous rip currents and high surf, likely leading to beach erosion along the Atlantic coastline and the lower Delaware and Chesapeake Bays. Coastal residents should closely monitor updates and follow any advisories issued by local emergency management or the National Weather Service.

    In addition to flooding, the storm could bring wind gusts over 45 mph, especially along coastal areas, which may result in scattered power outages and tree damage. Heavy rainfall could also lead to localized flooding inland, particularly in poor drainage areas.

    The Weather Prediction Center highlights the Delmarva coast as an area of elevated concern for strong wind gusts and coastal flooding potential this weekend.

    Residents are urged to stay alert as the system approaches and to secure outdoor items ahead of the storm.

  • Coastal Storm Possible This Weekend

    Coastal Storm Possible This Weekend

    After a period of very dry and chilly conditions over the weekend and throughout much of this week, we have a potential storm looming towards the weekend. Computer guidance has been hinting at a Miller B type of coastal storm to sweep across the northern tier of the nation and redeveloping a coastal low right off to our east.

    “Miller B Nor’easters is a low pressure system first tracks over the Midwest, bringing a swath of rain, sleet or snow to parts of the Plains. This storm generally moves into the Kentucky/Ohio River Valley before it starts to transfer energy to a newly forming low pressure system along the coast of North Carolina and Virginia. From here, the newly redeveloped storm takes a northerly path before making a turn out to sea.”.

    Our storm first develops across the Central Plains as a fairly strong system already on Friday before heading into our region on Saturday with rain and breezy conditions. Then the low begins to transfer off the coast of us and begins to redevelop with increasing northeasterly winds. European model ensembles really show a very good cluster of low centers right off the coast of Jersey showing there is a good potential for this to occur. So more than likely, get ready for more wind, rain, and coastal flooding going into the weekend with the new moon ahead.

  • *** Hybrid Storm Expected This Weekend / Wednesday Update ***

    *** Hybrid Storm Expected This Weekend / Wednesday Update ***

    Confidence continues to increase for some sort of sub-tropical in nature storm system to develop along a stalled out frontal boundary off the coast of Florida and Georgia. With a strong area of high pressure it place towards New England, this will allow this system to intensify and move in towards the Carolina coastlines late Friday through Sunday.

    Overspreading heavy rain, gusty winds, and coastal flooding are all expected this weekend. Especially on Saturday when the conditions are expected to be the worst out of this storm. Whether this storm will be tropical in nature or not, impacts are going to be felt like a stronger nor’easter we would see in the winter months.

    Rain will begin to overspread the region beginning during the overnight hours on Friday and picking up in intensity on Saturday. Rain will be heavy at times with many operational and ensemble mean totals of 2-5 inches are expected over the weekend. With an area of high pressure to north, a strong pressure gradient will setup with constant strong onshore winds from the east and northeast. Sustained winds of 20-30 MPH with gusts 40-50 mph at times, will help generate waves offshore 10-20 feet. Near the coast, we are looking at swells generating 7-12 feet.

    With some of the the tide gauge forecasts as of now showing areas along the Atlantic Ocean and Inland Bay regions for Minor to even Moderate coastal flooding during the high tide cycle Saturday afternoon. I worry for the Inland Bays a lot more with all the water being forced with no where to go given how big the swells will be with the strong long fetched onshore winds.

    It’s pretty definitive at this point that we have a coastal storm on the way, it’s just a matter of how much rain will be associated with this system, and if it happens to be tropical or not. Or even a combination of both being a hybrid sub-tropical system. More details will be provided as the week goes on.

  • Hybrid Coastal Storm Impacting Delmarva This Weekend

    Hybrid Coastal Storm Impacting Delmarva This Weekend

    With the potential hybrid storm coming this weekend, not only heavy rain and gusty onshore winds are a problem, these are going to be some big waves. Moderate coastal flooding is on the table for Saturday. With onshore winds of 40-50 mph wind gusts generating waves 10-20 feet offshore. That’s going to be driving water hard to the coastal locations. Inland bays will be the bigger issues where water will not have any place to go.

    We still have days to go to see the full extent of details but the consistency in model guidance is very good with this one so far. Whether this will be a tropical system or a nor’easter, this will be bringing heavy rains, gusty winds, and coastal flooding.

  • Another Winter Storm Looming To Close Out January?

    Another Winter Storm Looming To Close Out January?

    ECMWF Ensemble Low Plots from 00z

    Seems like every weekend this past month we are talking about another snow threat one after another. The only difference is that this one could become a powerful low off our coasts going into Friday and Saturday. With this being the end of the active weather pattern and signs showing for the persistent eastern trough will come to close with a more zonal flow (west to east parallel motion of the jet stream). Ensembles have been very persistent about a coastal low about 200 miles offshore with explosive development (aka bombcyclone) scenario with a rapidly intensifying oceanic storm that moves across the Gulf Stream. And some of these low placement strengths are nothing to take for granted. A good 80% of them are below 986mb pressure levels when its off our coast. By the time it’s off the coast of Cape Cod we are talking down into the 970s.

    Major Global Model Outputs For This Storm

    With a bit of surprise, there is actually some good agreement between the 3 major global models regarding this storm. ECMWF/GFS/CMC/ICON are on the table for a rapidly intensifying storm off our coasts this coming weekend. The biggest difference is how far offshore will it actually be. Every model without a doubt has a round of snow to the region but how close that low is will make a major difference. CMC/ICON are the most offshore out of the bunch with some light precipitation to the region and then dumping over coastal New England. GFS model coming in at 12z is a little bit westward giving Delmarva a good hit with snow. And then the big elephant of the group the ECMWF and the ensembles being very aggressive with a the furthest west solution giving all of Delmarva a major winter storm. And the ECMWF has been very consistent with that. Some of the ensembles give historic levels of snow but that’s extremely far fetched in my opinion.

    Overall do I think we have a explosive developing oceanic storm? That’s on the increase for sure to close out the weather pattern. It’s going to be a matter of how close will this get to our coast will make the big difference. We have the cold air in place ahead of this system to begin with. It’s something that we will be keeping an eye on this week.

  • Winter’s 1-2 Punch To Finish Out The Week

    Winter’s 1-2 Punch To Finish Out The Week

    HRRR Futurecast Only Until 7am Thursday

    Let’s first begin with the snow threat going into Thursday morning. We will be having a arctic front that will be slowing sinking southward across the Mid-Atlantic taking temperatures in the 40’s down to subfreezing. In addition with a transition of rain to snow behind that front with a weak disturbance riding along this front. Some of the high resolution model guidance have a good agreement that a changeover is expected during the morning hours Thursday.

    Cluster of Models Regarding The Snow Threat Thursday Morning

    Now i don’t expect anything significant regarding accumulations with this one but some could pick up a light accumulation. Especially those further north on the shore. We could be looking at some slippery travel in the area during the morning commute Thursday. Colder temperatures will continue to plummet throughout Thursday into Friday just in time for the second and maybe even more significant threat.

    Arctic Front Settling Thursday-Friday

    When the passes through we are going to see a fresh supply of arctic air with temperatures dropping down into the teens Thursday night and really struggling to get anywhere near 30 on Friday. This is setting up the stage for round number 2.

    Model Solutions Regarding Snow Threat Friday-Saturday

    Now this is where the really messy situation begins. Unlike the last bigger snow threat to Delmarva, we have some of the best model consensus I have seen in quite some time which made it easy. Well it’s back to the confusing nightmare once again. So let’s break things down into groups.

    ECMWF/ECMWF ENSEMBLES/UKMET/NAM

    This group is the very aggressive solutions where we are showing a January 3rd snowstorm repeat across much of the region. Snow and a lot of it too. With the phasing of two jet streams allowing for a low to develop down in the Gulf Of Mexico and move off the Carolina coast. With a strong 1038mb high to north keeping that fresh arctic air locked in. This is a snow lovers dream with a textbox major snowstorm for the Mid-Atlantic. The EURO model has been very persistent with this solution for the last several days but for awhile it was alone in that matter. The recent NAM model even though its not out far enough to really see the impacts, but its very aggressive and further northwest. UKMET has a limited amount of products we have access too but its also following the more northwest solution. Now going into the ensembles, there is a very tight agreement in low placements with the 52 members of this model. With some heavy hitting more reliable models getting on board with this solution, it’s something to take note of for sure.

    Messy Solution With Multiple Energy Pieces Not Phasing

    GFS/RGEM/CMC

    Now this group of models keeping all the pieces of energy separate with a much weaker and suppressed solution. We are going to have model runs like because there is so many different pieces these models are going to have to figure out what to do with them. Not 1, or 2, but 3 vort maxes in play. I’m going to be honest especially with the GFS model, It’s creating some very unrealistic movements with that northern piece of energy near Ohio by ejecting that straight east even though its pashing with that southern one near the Gulf States. Can that still happen? Of course but it’s on the low end of my scale right now. We really need a aircraft to sample the upper atmosphere in the next day or so to be ingested to these models so we can get a bit of better censuses. They did this for the storm occurring for MLK day and that’s why we had a major shift in the track to being much more inland.

    Overall Thoughts

    As it stands now for Friday into Saturday, we have a lot time to work out the kinks and we are going to be seeing some back and forth movement with solutions until we get these pieces of energy into range of observational data and or a aircraft to do research into the atmosphere the next 24 hours. I will be keeping a very close eye on this one that’s for sure.

  • High Wind Event With Coastal Flooding Concerns Sunday Night

    High Wind Event With Coastal Flooding Concerns Sunday Night

    Not only we have to deal with some heavy rainfall, a little bit of snow for the northern areas of Delmarva and the Maryland Western Shore. There’s an event that is sleeping under the radar that has my full attention. When that low starts dropping below 990mb, that low level jet stream is very strong being pulled into this surface low.

    70-80kt Winds at 850mb ( Low Level Jet)

    Anytime I start seeing winds at 5000ft getting over 60kts, I get a bit uneasy in the damaging wind department. This is a long fetch stream of onshore winds we are talking about from the Gulf Stream. There is going to be a lot of wind energy pushing on the east side of this low. And it’s all onshore flow too. There’s more issues with this as well.

    NAM and GFS Surface Wind Gusts Forecast

    Winds at the surface are showing widespread wind gusts of 40-60 mph from the east and southeast. Another problem surfaces as well. We have a high tide cycle that’s expected during the evening hours Sunday Night. To add more salt in the wound, this weekend is a full moon as well. So take 40-60mph surface winds, plus onshore flow, plus a high tide cycle, and a full moon, it’s not going to be a fun time for a coastal locations this weekend. Strongest winds appear to be in a window from 8pm Sunday until 4am Monday.

    Already a few tidal forecast in the region showing Moderate Flood Stage forecasts like this one in Crisfield. So we really got to watch our coastal regions Sunday night for flooding concerns.

  • Major Coastal Storm On The Way Sunday-Monday

    Major Coastal Storm On The Way Sunday-Monday

    GFS Model Output For Sunday

    A very dynamic storm system is on the way for the Eastern US going into this weekend. Widespread areas of heavy snow, freezing rain, sleet, and rainfall are all on the table stretching from the deep south all the way into New England. A classic Miller-B type of Nor’easter.

    500MB Pattern

    Storms that come in from the west (up the Ohio Valley) are usually referred to as “Miller Type-B” storms. These storms produce precipitation in the Midwest/Ohio Valley and have a defined surface low that is moving toward the Appalachian Mountains from the west. As these storms approach the mountains, they lose their coherent/compact surface low center and the low re-develops along the East Coast. When this re-development (a.k.a. “center-jump”) happens, the storm can still produce snow over all of the state.

    NAM Forecast Regarding Ice Threat

    With a storm diving straight from Canada across the Northern Plains will run directly into the sub-tropical jet-stream. Tapping into moisture from the Gulf of Mexico to really give some power to this low. I have a big concern for those in the Western Carolina’s and Northern Georgia regarding the ice threat. With cold air damming present along the Appalachians and the arctic high to the north, this is not a good situation for residents in the Southeast US.

    Great Model Conesus On Track Today

    With the energy associated with this system now over land on the West Coast, we are getting a fairly firm track on where this system is going to go. Unfortunately those on Delmarva hoping for another big snowstorm, this is not the one. With a track of the low pressure right over the Peninsula, a lot of warm air will surge in. Although areas may start off as a snow/sleet mix will change over to all rain once the low pressure center gets closer. Our friends on the Maryland Western Shore will have a little bit longer duration of snow and sleet thanks to Cold Air Damming before they will change over to all rain as well.

    Snow Depth Forecast

    Those who live along the Appalachian mountains in Western North Carolina, Virginia, West Virginia, and Central PA are in for a doozy of a snowstorm Sunday and Monday. Widespread areas of 6 plus are definitely likely. Areas like Washington DC through Frederick Maryland could sneak in some light accumulations at the start being turning into a sloppy mess once temperatures start rising above freezing when the low approaches.

  • Big Storm On The Way Sun-Mon / Snow Lovers Won’t Be Happy With This One

    Big Storm On The Way Sun-Mon / Snow Lovers Won’t Be Happy With This One

    Surface Pressure Forecast

    We gave out two different solution tracks in yesterday’s update but now we have a agreement on which one it would be. If you guessed number 1? You are right (sort of). For reference to yesterday’s post –> https://tvdelmarva.com/storm-signal-jan-16-17th-winter-storm-looming/

    Many models have trended with a storm system riding up the Eastern Seaboard thanks to the added ingest from an aircraft last night sampling the atmosphere on the West Coast. This created a big shift in the over track and unfortunately for snow lovers, not in a way that favors Delmarva.

    GFS timeframe showing Snow/Mix changing to rain across the region

    With a low pressure track right over the Peninsula, We will start out with a snow/sleet mix and eventually all locations will be changing over to rain. Delmarva will see that transition fairly quickly but those across the bay on the Maryland Western Shore. They are looking to see a longer duration in the snow & sleet part of the storm thanks to cold air damming along the Appalachian mountains. Eventually they will also change over to rain.

    ECMWF/CMC/GEFS all following suite to the blend

    With agreement from the ECMWF, CMC, and the GFS Ensembles following the same path, it’s looking that areas of Delmarva will be going from a extremely cold Saturday to a very chilly rain on Sunday. There is still several days away for this storm to be in the region but its not very often / likely these will trend eastward to favor our snow lovers here on the shore.
