Philadelphia, Pennsylvania – A broad warming signal is emerging across Pennsylvania as February transitions into March, increasing the likelihood that winter’s most persistent cold eases during the Feb. 28 through Mar. 13 timeframe.
According to the National Weather Service Climate Prediction Center, Pennsylvania carries a 33% to 50% probability of above-normal temperatures in the Week 3-4 outlook. That warmer signal spans the entire commonwealth, from western counties near Pittsburgh along Interstate 76 and Interstate 79 to central corridors along Interstate 80 and eastward through the Interstate 95 corridor in the Philadelphia metro.
This extended-range guidance favors more seasonable to slightly milder conditions compared to late-February averages. While brief cold snaps remain possible, the broader atmospheric pattern suggests fewer prolonged Arctic intrusions affecting major population centers including Harrisburg, Scranton, Allentown and Philadelphia.
Precipitation probabilities during the same period lean near normal statewide. No dominant wet or dry anomaly stands out in the long-range outlook, indicating that typical late-winter systems remain possible without a strong signal for excessive snowfall or extended dry stretches.
Communities across western, central and eastern Pennsylvania fall within this gradual transition toward early-spring conditions. The Week 3-4 outlook reflects large-scale atmospheric trends rather than specific storm timing or day-to-day details.
Further refinements are expected as the late-February to mid-March window approaches and shorter-range guidance provides additional clarity.
