This morning, high pressure is building south and east from Ontario into Mid Atlantic providing clearing skies and a colder Polar air mass.
Current analysis of this air mass still suggest that this Polar air mass is being moderated and the warm temperatures of the past several days is having an impact to the boundary [...]

A light snow event is going to unfold on Friday morning, but the details remain uncertain as much depends on the evolution of mesoscale parameters. So this morning, I’m going to try to clear some of the fog and mist of this time period and discuss the potential that exits and why it [...]

Obviously tonight all of our focus is on the storm that is on the way for Saturday. This afternoon, the model guidance took a strong swing towards what I defined two days ago as scenario 3, which is a full phase intense winter storm that is capable of producing significant snowfall. Given the data [...]

This evening, cold air is starting to work into the northern Mid Atlantic after a very warm afternoon ahead of a strong cold front. Temperatures will continue to fall through the 40’s and into the 30’s by tomorrow morning.
Tonight is going to be an interesting run on the model guidance. The 12Z guidance still [...]

A deep trough is expected to develop over much of the western two-thirds of the nation, which will keep a ridge in place over the Gulf Coast and much of the Mid Atlantic.

After an active evening and overnight period of showers and thunderstorms, which produced damaging hail, wind gusts, and flash flooding, the trough responsible for the thunderstorms is now beginning to lift into eastern Canada. As a result, the forecast area will be under the influence of sinking air, which will support weak high pressure [...]

This morning, despite the passage of the “cold front” yesterday, the forecast area is in a warm and humid air mass. This [...]

I’ve looked at the 12Z guidance and 18Z guidance, and frankly I haven’t changed my thoughts on the situation leading up to Sunday. The upper level features and storm track from 00Z to 12Z on the ECMWF hasn’t changed much, however the guidance does include higher QPF for the forecast area. Meanwhile, the GFS [...]

There’s a lot of excitement over the trend of the model guidance towards a colder solution for Tuesday night and Wednesday, specifically the 18Z GFS.
While I can understand the excitement, I want to state that the 18Z GFS does not exactly have the strongest of support. While I agree that a coastal low is [...]
