7:00 AM | *Strong-to-severe thunderstorm threat late today/tonight…cool air mass arrives this weekend* — Perspecta Weather


6-Day forecast for the Philadelphia, PA metro region


A summer-like feel to the day…Mainly cloudy skies although there can be some sunny intervals, breezy, warm, very humid, chance for a shower or two through the early-to-mid afternoon hours, but much of the time will be rain-free, showers are more likely for the late afternoon and there can be a late day strong thunderstorm, highs in the lower 80’s


Evening showers and thunderstorms likely, some of the storms can be strong-to-severe, lows in the mid 60’s


Becoming mainly sunny, warm, upper 70’s for afternoon highs

Saturday Night

Mainly clear, turning quite cool, low-to-mid 50’s for late night lows


Mainly sunny, breezy, cool for this time of year, upper 60’s


Mainly sunny, still on the cool side, upper 60’s


Mainly sunny early, clouds late, cool, lower 70’s; showers likely at night


Partly sunny, a bit warmer, chance of showers and thunderstorms, mid 70’s


A pre-frontal trough of low pressure will approach the region later today and then a strong cold front arrives in the overnight hours. Ahead of the trough and frontal system, there can be an occasional shower through the early-to-mid afternoon hours, but most of the time will be rain-free. The main action takes place late today and tonight as showers will become more likely and there can be a strong-to-severe thunderstorm as well. Skies will clear tomorrow morning and then a much cooler air mass will pour into the region tomorrow night and Sunday. In fact, the cool air mass arriving this weekend will be quite a bit below-normal for this time of year and the month of June could actually start off on quite a chilly note early Monday morning (June 1st) with temperatures bottoming out in the 40’s across many of the northern and western suburbs.
