We’re watching a weak disturbance that will swing through the Mid-state this evening. This will develop scattered, light showers through about 11p before the activity exits northeast. Only light rainfall amounts are expected, with just a stray shower possible overnight into first thing Wednesday morning.
A potent cold front will then cross Pennsylvania tomorrow, bringing gusty mid-day (10am-2pm) showers with it, but more noticeably, much colder air to end the week. Highs tomorrow will be in the lower 60s, but will quickly plummet in the afternoon once the front passes. Wind gusts of 30-40 mph will be common along and behind the front before lessening a bit tomorrow night. It will turn quite cold Thursday morning with low temperatures falling all the way into the low 30s. Frost is not a concern given the high winds, but a light freeze may occur especially north and west of Harrisburg where temperatures could drop closer to 30 degrees. Cover those sensitive plants!
Thursday’s winds will pick up again with a reinforcing shot of cold air. Watch for wind gusts over 35 mph at times which will make it feel more like the 30s and 40s most of the day!
Despite the chilly start, highs rebound on Friday with more sunshine back into the 60s. Temperatures do moderate slightly by the weekend, with our next best chance for rain coming Saturday night into Sunday morning. Conditions look to dry out and warm up as we head toward the middle of next week.
