Still a cool Tuesday!

 

Current Setup

 The last couple of days have been downright cold for this time of year. Last night saw most of the Northeast dealing with freeze watches and warnings.

But many of y’all know it could be worse as a winter storm is set to strike the California mountains with up to two feet of snow this week

Surface Chart, Radar and Satellite.





We have high pressure overhead that is sliding east, ahead of a frontal system centered over the Upper Midwest. Radar shows other than lake enhanced rain/snow showers associated with a weak trough up over Central New York State, most of which isn't reaching the ground, the region is dry. As the snow/rain tries to move south and east it is going to dry up.

Today is going to warm a bit ahead of that approaching warm front as it moves in later Tuesday into Tuesday night may trigger a few showers this evening into Tuesday night, but for the most part Tuesday looks dry.

Rest of this week

Come Wednesday, we will see some sun developing during the afternoon after a few left-over spotty showers earlier in the day. Temperatures will be much warmer by Wednesday.  Thursday will see high pressure build back into the region. Thursday night and Friday we’re going to be setting between two areas of low pressure, one will be up near the Gulf of Maine, while the other is going to be over the Midwest into the Central Great Lakes. Friday will see a backdoor cold front drop south and west out of New England, that will run into milder air trying to push into the region due to the location of that low pressure near the Great Lakes. This will lead to a stationary front that will set up over New York State and Pennsylvania. North and east of the boundary, temperatures are going to be much cooler than they will be south and west of the boundary.  We can expect to be dealing with a few scattered showers. Thursday and Friday will see temperatures become very seasonal.

Friday night and Saturday, the low pressure with a cold front to the west is going to approach and move through. With this we will see widespread showers move across the region. There could be some snow/mix across the higher elevations.  The low pressure with the cold front will be pushing to the south and east by Sunday. Temperatures will warm as the region see a lot of sun develop. Monday will see high pressure build into the region. But in spite of the sun temperatures will be seasonally cool. On Tuesday a stronger area of low pressure will move in, bringing widespread rain and higher elevation mix/snow showers back into the region. This rain could be very heavy at times.  General rainfall amounts of 1-3 inches could lead to some flooding concerns.  



That's it for today.
