Wednesday Night

Synopsis

Conditions will cool off greatly tonight in the wake of a cold front that passed through the region earlier this evening. A short-lived area of high pressure will build into region late Thursday. A shortwave will race across the state bringing a chance of precipitation Friday and Saturday. Warmer conditions will make their way back into the forecast on Sunday and remain into early next week as a high pressure builds into the Eastern U.S.

Short Term

Winds are currently turning north-west and overnight a northwesterly flow will dominate the state. This flow will allow for some cloud cover and some cold air advection. As a result, conditions will be much cooler on Thursday than Wednesday. As the winds calm down on Thursday, clouds will begin to clear up. Clear skies will prompt temperatures to dip into the upper 20s causing a freeze in a large portion of the state. 

Long Term

Friday evening a shortwave will move into the region from the Midwest. An associated surface low pressure system will move into the region Friday night/Saturday morning. Scattered showers and generally cool conditions are expected for the duration of the event. At the moment there is a lot of uncertainty pertaining the timing of the shortwave. Precipitation could impact the commonwealth anytime between Friday afternoon and Saturday afternoon. A high pressure system will build into the Eastern U.S. during the day Sunday. Mild and calm conditions will follow and remain into early next week.
