Weather Outlook for the Week of June 2, 2026

A large ridge of high pressure parked over the Midwest will slide eastward through the Mid-Atlantic during the middle of the week. Afternoon temperatures will be mainly in the 80s with lows in the 50s. By Friday, the ridge will move off the East Coast, and southwesterly winds on the west side of the high-pressure center will bring increasing temperatures and humidity levels on Friday and Saturday. Parts of southern Pennsylvania will likely top the 90-degree mark late in the week into the weekend. An approaching disturbance from the Great Lakes will bring a front through the state on Saturday into Sunday, bringing a chance for showers and thunderstorms through the end of the weekend. Models diverge on whether the front stalls for the start of next week. If it would stall near the region, continued showers and storms are possible through the middle of next week, but any rain would come to an end by Monday if the front travels farther south and east. Rainfall totals of between one half of an inch to one inch of rain are expected for most areas through the middle of next week.

Long-range model guidance continues to indicate slightly above average temperatures and near normal precipitation for the rest of the month of June.
