Weather Outlook for the Week of April 27, 2026

On Wednesday, a low will cross the Mid-Atlantic, bringing widespread showers and periods of rain to the state. The low will drag a cold front through overnight into Thursday morning, which will bring chillier weather to the region as highs in the afternoon will be in the 50s and low 60s, and lows will drop into the 30s and low 40s by Friday morning. Frost and freezing conditions are likely across at least the northern half of the state on Friday and Saturday mornings with the colder air in place. During this time, an upper-level trough will remain parked over the eastern United States, which will bring scattered rain showers, potentially mixed with some snow at times across northern Pennsylvania, starting Friday and continuing through the weekend.  Unsettled weather will persist through the start of next week as another disturbance approaches the state from the west and temperatures remain below seasonal through the middle of next week before moderating to closer to average by the latter half of next week. Most locations should observe at least one-half to one inch of precipitation by the middle of next week.

Long-range model guidance indicates seasonal temperatures and near-average precipitation for the month of May.
