Latest Forecast

A moisture-starved cold front will traverse the Commonwealth tonight. Behind it, a Canadian high pressure system will settle into the eastern Great Lakes region on Thursday and bring cooler conditions to the Lower Susquehanna Valley. Despite abundant sunshine, high temperatures will be around 5 degrees below average Thursday afternoon. A north-northwesterly breeze of 12-25 mph will persist and make the outdoor air feel even chillier, as well. The area of high pressure will shift into the mid-Atlantic States from Thursday night into Friday and cause winds to slacken. In addition, temperatures will remain slightly below average despite plenty of sunshine. This high pressure system will then shift into the western Atlantic Saturday. The south-to-southwesterly flow on it's backside will usher in much warmer air for Saturday afternoon.
