Synopsis
A ridge is currently in place over the mid-Atlantic region of the country. This is providing generally rain free conditions for much of Pennsylvania. Areas up north in the keystone state are experiencing some precipitation and clouds associated with a frontal boundary. This should continue to impact our area into tomorrow. A trough will bring rain followed by snow showers in some places especially to our north Thursday and into Friday.
Short term
This boundary should keep clouds and precipitation around our area and especially in northern sections of the state over the next day or so. The NAM brings in rain showers across the west early tomorrow and has them lingering across the state as the day continues on. A low pressure system will follow in late Wednesday into Thursday bringing rain to much of our state.
Long term
Unsettled weather will be the story for Thursday. Much of PA will find some rain during the day. Temperatures should remain above freezing throughout much of the time period until late Friday. The SREF has a fairly high chance of snow showers developing late in the north central region once the frigid air builds in with the passing of the front. It doesn't appear to be anything substantial accumulation wise. All precipitation should exit by Friday morning leaving cold air behind. The 12 km NAM keeps high temperatures across the state in the 30's and 40's over the weekend. The European currently brings in a system which could produce a fair amount of snow on Saturday. There is little consensus pointing to this happening at this point. Time will tell.
