EVENING: Clear and chilly. Temps dropping into the 30s.

TONIGHT: Mostly clear and chilly. Low 30

TUESDAY: Increasing clouds, rain arrive and mixes with wet snow after 2pm. High 44.

Tonight’s temperatures fall below freezing, setting the stage for a chilly rain (and even some wet snow!) to develop tomorrow afternoon. Clouds increase tomorrow morning ahead of an area of low pressure moving northward from the Gulf. This low will overspread the region with a chilly rain tomorrow afternoon (after 2 PM for areas along the southern half of I-81). It could start as a period of wet snow, especially for areas north and west of Harrisburg. Even in these regions, temperatures will remain above freezing. After this initial burst, most places will see mainly rain for tomorrow afternoon and evening and continuing into early Wednesday morning. Around 0.50″ of rain is expected across the region.

Skies clear on Wednesday, but temperatures stay chilly. It will be breezy both Wednesday and Thursday behind the system. Some lake-effect rain and/or snow showers could develop Thursday, and then another shot of cold air will follow for Friday and the weekend. Highs this weekend will be in the upper 30s to around 40°. Overnight lows will drop below freezing and will likely be in the 20s for several nights in a row. While no major weather systems appear in play beyond tomorrow, the chill appears to last for quite a while and gets reinforced over the weekend. Bundle up! We’ll keep you posted.
