  • Wintry Mix Followed By Arctic Cold To Finish Work Week

    Wintry Mix Followed By Arctic Cold To Finish Work Week

    A developing storm system will bring a brief period of light rain to Delmarva late Wednesday, with the potential for a few snowflakes before the precipitation ends early Thursday. While impacts from precipitation look minimal, the bigger story will be the sharp drop in temperatures and strong winds that follow and last into Friday.

    On Wednesday, a cold front associated with a passing system to our north will move through the region. This front will help produce a shield of light precipitation across the area Wednesday afternoon and evening. With temperatures starting off mild, most locations on Delmarva will see rain initially. As colder air moves in overnight, rain could briefly mix with or change to snow before ending early Thursday morning. Any snow accumulation is expected to be very light, with little to no impact expected across Delmarva.

    A secondary storm system is expected to develop offshore along the Carolina coast late Wednesday night into Thursday. Current forecast guidance keeps this system well offshore, meaning it should have little to no effect on our region. Because of this, confidence remains high that Thursday will be largely dry, aside from a small chance of lingering light precipitation early in the morning.

    Temperatures will be relatively mild ahead of the front on Wednesday, with highs ranging from the mid 40s to near 50 degrees across Delmarva. Conditions will change quickly Wednesday night as colder air pours into the region. By Thursday morning, temperatures will drop into the mid 20s to near 30 degrees. Strong west to northwest winds will develop, creating wind chills in the teens and lower 20s through much of the day.

    Thursday will feel bitterly cold and blustery, with sustained winds of 15 to 25 mph and gusts occasionally reaching 30 to 35 mph. Afternoon temperatures will struggle to recover, only reaching the upper 20s to mid 30s despite some sunshine.

    The coldest air arrives Thursday night into early Friday. Overnight lows will fall into the teens and lower 20s across Delmarva, and persistent winds will push wind chills into the single digits by Friday morning. Friday remains cold, with highs once again in the upper 20s to mid 30s and wind chills staying in the lower to mid 20s.

    While this system will not bring significant precipitation, the combination of strong winds and sharply colder temperatures will make it feel more like mid winter across Delmarva heading into the end of the week.

  • Colder Pattern Looks to Take Hold Across the Eastern U.S. Through Late January

    Colder Pattern Looks to Take Hold Across the Eastern U.S. Through Late January

    A noticeable shift toward colder than average temperatures is expected to develop across much of the eastern United States over the next few weeks, according to the latest temperature outlooks from the Climate Prediction Center. Multiple forecast periods show increasing confidence that below average temperatures will dominate the East, including the Mid Atlantic and Delmarva region.

    6 to 10 Day Outlook: Cold Begins to Push East

    During the 6 to 10 day period, colder air is forecast to expand across much of the eastern half of the country. Below average temperatures are favored from the Midwest through the Ohio Valley and into the Mid Atlantic and Southeast. The Delmarva Peninsula falls within this colder zone, signaling a transition away from recent mild conditions.

    While the strongest cold anomalies are centered farther west early on, the overall pattern supports repeated intrusions of cooler air into the region. Daytime highs are expected to trend several degrees below normal, with overnight lows becoming more seasonable to colder than average.

    8 to 14 Day Outlook: Below Average Temperatures Become More Established

    Confidence increases during the 8 to 14 day period as below average temperatures become more firmly established across the eastern United States. The cooler air mass expands and deepens, covering much of the Mid Atlantic, Northeast, and Southeast.

    For Delmarva, this period favors a sustained stretch of cooler conditions, especially during nighttime hours. Persistent northwest flow behind passing systems may keep temperatures suppressed for several days at a time.

    Weeks 3 to 4: Colder Pattern Persists

    Looking ahead into weeks 3 and 4, the temperature outlook continues to favor below average conditions across much of the eastern United States. While forecast confidence naturally decreases at longer ranges, the signal remains consistent for a cooler than normal pattern.

    Across Delmarva, this suggests limited warm ups and continued winterlike temperatures heading into late January. Brief periods of moderation may occur, but cooler air is expected to return frequently as the broader pattern remains favorable for below average temperatures.

    What This Means for Delmarva

    For residents across Delaware, Maryland’s Eastern Shore, and Virginia’s Eastern Shore, the next few weeks are expected to feature a noticeable chill compared to normal January conditions. While temperatures will fluctuate, the overall trend points toward a colder pattern settling in across the region.

    Overall, the outlook supports a sustained period of below average temperatures across the eastern United States, with Delmarva remaining solidly within the cooler regime through much of the remainder of January.
