EVENING: Occasional showers, temp in 40s.
TONIGHT: Rainshowers transition to snow showers after 10pm. Light snow, mainly south/east I-81. Temps fall into 30s
WEDNESDAY: Decreasing Clouds, Breezy, Colder. Hi 37. Winds: W 5-15 mph.
We are wrapping up a mild and damp Tuesday and now temperatures are starting to dip into the 40s. Colder air continues to filter southward into the state tonight. This will allow the rain showers to transition to snow showers, mainly after 10pm. Our weather team believes a band of snow will develop south and east of Interstate 81 overnight. Counties including Adams, York, Lancaster and Lebanon counties have the best chance of a slushy snow accumulation. An inch of snow may be common, with a few spots reaching 2 inches of snow before sunrise Wednesday morning. The rest of the Midstate will see occasional snow showers with little to no accumulation.
After some early clouds tomorrow morning, skies will clear and the sun will return for Wednesday. It will be much colder and breezy, however, with high temperatures in the 30s! Lows in the teens are possible by Thursday morning as we get grazed by an Arctic air mass. High temperatures from Tuesday into Wednesday will drop by around 20 degrees as the colder air takes hold! Thursday will be the coldest day of the week but also the sunniest! Temperatures do trend upward by late week, but so do precipitation chances. The influx of warmer air should prevent major wintry concerns but it looks like another wet period is likely from Friday night through Saturday. Stay tuned!
