We have been talking about this scenario throughout the week about a major storm system will be developing in the Eastern half of the nation. An area of low pressure will be rapidly developing from the Gulf States and runs parallel through the Mid-Atlantic states during the morning hours on Saturday.
Phasing of the Northern Jet and the Sub-Tropical Jet will set the stages of a potential Bomb Cyclone (air pressure that drops more than 24mb’s in 24 hours) to develop. By the time this storm system moves north of New England we could be looking at some serious low pressures by Greenland.
Depending on the placement of this area of low pressure will determine if we are in the path of the powerful low level Jetstream to setup. The blend solution has the area of low pressure going right over the Delmarva region keeping those powerful winds off of our coasts. But if the low positions further west, this will allow for a short term duration of strong winds exceeding 50 mph at times.
To add more dynamics to the mix, cold air will be crashing on the northwest side of the storm which we may see a burst of snow on the backside during the evening hours. Any snow that does fall will have a extremely difficult time accumulating here on the shore. It’s a matter of how quickly can those temperatures crash on that backside of the storm. And the position of the low. If we have a further east solution like the NAM3km, then our chances are high but I have that one as my outlier as of now. I’m leaning more with the HRW-ARW with the further west solution overall.
