Synopsis: A cold front will move through the state later this evening. Northwesterly winds behind the front will usher in much cooler air. An area of high pressure will move through the region later tomorrow into Friday, bringing fair weather. An area of low pressure will move south of the state later Friday night into Saturday bringing the threat of showers.

Short Term (Tonight into Thursday Night): A brief shower is possible as the front passes through later tonight. Behind the front, a gusty northwesterly breeze will develop ushering much colder air. Temps will be at least 15 to 20 degrees cooler tomorrow than what it was today. Clouds will decrease throughout the day as high pressure moves over region. Tomorrow night will be a cold one with clear skies and light winds, however, temperatures will not be as cold as Tuesday morning.

Long Term (Friday Through Saturday): Clouds will increase on Friday ahead of the next disturbance, which will pass south of the state. There is general consensus among the European and GFS models that showers will spread into Western PA by late afternoon and through the rest of the state throughout Friday night. The showers end by late Saturday morning. Fair weather will return on Sunday as the area of low pressure exits off the east coast.
