The region is currently positioned in a dry zone between weather systems affecting the Great Lakes and southern Appalachians.
This favorable pattern will maintain mostly clear to partly cloudy skies tonight with overnight lows between 30 and 40 degrees. Light winds and dry conditions will persist through Monday morning.
A moisture-starved cold front will cross the area Monday, bringing breezy conditions that will extend into Tuesday. Wind gusts of 20 to 30 mph are expected across the northwestern half of central Pennsylvania, with isolated showers possible in the northern tier downwind of Lake Erie on Monday afternoon.
Temperatures will remain seasonal but trend slightly lower on Tuesday, with highs in the lower 50s to near 60 degrees.
The weather pattern shifts on Wednesday as a series of fast-moving systems brings multiple rounds of precipitation. The first significant chance for showers arrives Wednesday evening through Thursday afternoon.
Additional periods of rain are expected between Friday evening and Sunday, with each system accompanied by breezy to windy conditions.
For higher elevations in the northwest mountains, there’s a marginal chance of mixed rain and snow showers on Wednesday night, with a more robust signal for snow showers on Saturday night into Sunday. Travelers in these areas should monitor forecasts as the weekend approaches.
