Several frontal boundaries extend from Maine to Texas bringing showers to much of the eastern U.S. As the fronts move eastward, periods of light rain showers will affect the region today.
Yesterday, these fronts were west of the Midstate, putting our region in a warm sector. As these fronts move to eastward, much cooler air will sink into the Commonwealth. Plan for a mild start to this Thursday (50s), with temperatures falling into the 40s by later this afternoon!
One side note: even though showers will continue off and on throughout the day, total rainfall amounts will be on the light side. Most areas will not see more than 0.50″.
The coolest air of the season reaches the Midstate on Friday. Temperatures will sink into the low 30s Friday morning, leading to our first freeze of the season. The chilly air mass will limit our high temperatures to just around 50 on Friday, with enough dry air to keep the region mainly sunny.
The weekend weather still hinges on a developing coastal low pressure system. Data over the last couple of days showed this low pressure staying east, leaving us with a pleasant weekend. But some recent data is showing this low a little closer to the coast, which could mean some rain and/or light snow could be possible Saturday.
We still have a few days to monitor the development of this low pressure system. We will keep you posted.
