THIS EVENING: Chilly Rain. Temperatures Falling To Near 45.

TONIGHT: Rain Ending, Clearing Skies. Lo 40.

THURSDAY: Partly Cloudy, Breezy, Evening Showers. Hi 63. Winds: NW 10-15 mph. Gusts to 25 mph.

We should slowly clear out overnight as weak high pressure builds in. It will be a chilly start to Thursday as temperatures bottom out in the upper 30s to near 40 degrees tomorrow morning. The afternoon looks decent though with sunshine and temperatures pushing into the low 60s. It will be breezy however with westerly winds around 10-15 mph.

A cold front will cross Thursday night, ushering in more chilly air for Friday. Before the front crosses, there may be a passing shower Thursday evening. An area of low pressure will then develop along the front Friday, developing a winter-like storm with rain for most but snow on the back-side (mainly over western Pennsylvania). Wet snow could mix in in a few spots locally late-day as colder air builds in. Highs Friday will be lucky to escape the 40s, and temperatures by Saturday morning will fall close to freezing, getting close to the record low of 32 degrees. There will be freeze concerns especially with how far along we’ve gotten into the growing season.

Sharply cold air moving in aloft for Saturday may generate additional rain/snow/graupel showers. A few squalls remain possible across northwestern Pennsylvania, though the bigger story locally will be the chilly air and strong wind gusts that may exceed 35 mph.

By Sunday morning, temperatures will drop into the mid-30s again, getting awfully close to the record low of 32 set back in the 1960s. We’ll have to watch for a potential freeze again in some areas as our northwestern communities may fall to freezing or slightly below. The good news is Mother’s Day itself looks dry with sunshine and more tolerable temperatures by the afternoon.

Early next week will continue the theme of below normal temperatures, with 50s and more rain expected by Monday. It appears a pattern change will finally take place toward the middle of next week! A little preview: We may get into the 70s by next Friday! Hang in there!
