Friday Update on Next Week's Event...

While we may still see a few snow showers/flurries late Saturday night and early Sunday morning, our attention is clearly focused on the significant storm for the middle of next week.

Today's model runs continue to favor a storm track to our west along a front approaching the Mid-Atlantic. That means ways of moisture bringing periods of showers beginning Tuesday and continuing through Thursday. However, the last wave could still prove to be somewhat interesting on Thursday. Here's a look at the data...

First, the European model, which clearly shows the mild flow ahead of the system and waves of moisture for both Wednesday and Thursday...





















Now for the GFS, first off Wednesday morning's map, which agrees with the European and shows a milder day (temperatures probably in the 50s) with waves of moisture producing showers.








The last wave is what could prove interesting. The first map shown below if for Thursday morning, with a surface low developing way down south and high pressure anchored to the north. The high is a little too far north to drive enough cold air south for wintry precipitation here.













Then here's Thursday evening's map (effective 7 P.M. Thursday), which shows the surface high moving out of the way to the northeast, while the powerful storm moves up through the Delmarva. It would be too warm for winter weather along and east of I-95, but the mountains could get some snow in this scenario. That's the latest for now...we'll see what developments evolve over the weekend.
