Thursday Eveing Techincal Discussion

Synopsis

As the 500-mb trough approaches the area, there is the chance for snow showers in the northwest areas overnight. As this upper level trough moves through on Friday, conditions will remain cold and blustery. Behind this trough, an area of high pressure will build in this weekend.  There is a chance that a cold front will move southward into Pennsylvania around next Tuesday.

Short Term

The cold front that went through the area this afternoon has caused temperatures to drop. Temperatures will fall slowly tonight as there should be winds and clouds. Expect northern zones to have lows in the upper 20's and in southern zones in the lower 30's Friday morning. Skies will remain cloudy on Friday and temperatures should not go very far as the 850 mb temperatures are -4 to -6 C and there is strong cold air advection. High pressure will build on Saturday which will promote dry and clear conditions. This will allow temperatures to moderate some into the 50's.

 

Long Term

Skies look to be remain dry and sunny for the weekend as the ridge continues to build in. Temperatures should stay in the 50's Sunday. Some clouds will work their way back into the area Monday as a cold front approaches the area. During the day on Tuesday, a cold front should move through the area and bring a chance of showers. This will bring some cooler temperatures for Wednesday.
