Our very slow start to severe weather season continues, but as temperatures warm back up, so will our opportunities for the usual summertime afternoon thunderstorms. Our next chance for strong to severe thunderstorms is Thursday. Showers will develop in central and western PA Thursday morning in the warm sector ahead of an approaching weak trough.…
After an unusually quiet start to severe storm season here in PA, Wednesday looks to bring the potential for two lines of thunderstorms ahead of a cold front. Typically when looking at a linear threat, damaging winds are the main risk, and that will apply on Wednesday as well. We also cannot rule out isolated…
The heat will continue this weekend, with highs getting into the 80s across most of the state. A few places may even hit the 90 degree mark, likely near Philadelphia.

A warm and humid day is on tap, and unlike yesterday, we expect some sun to break out by the late morning.

After yesterday’s severe thunderstorm threat didn’t pan out above the PA/MD line, today looks to be a near-repeat. While most of the severe activity today should be south of Pennsylvania, a few storms are possible in far southern PA. Main threats include damaging winds, with a tornado threat south of the state. THURSDAY SEVERE THUNDERSTORM…
We are back talking about the threat of severe thunderstorms both today and Thursday. A cold front sweeping in from the northwest will interact with a moist air mass over much of the state and result in the development of pop-up strong to severe thunderstorms today.

Our streak of severe weather is finally set to end today. It has been an impressive run for any time of the year, but especially late August. From here we will enter an up and down pattern, with frequent temperature swings and chances for rainfall. It’s hard to believe there are only four months left…
Yet another round of scattered thunderstorms is on tap for today, some of which may be strong to severe. Primary threats include damaging winds in intense cells and isolated hail.

As Hurricane Laura continues to move inland, we will be monitoring that and also the threat for severe thunderstorms here in Pennsylvania Thursday (not associated with Laura).

The weather has been quiet for a while, but we are once again having a lot thrown at us at once.

Potent clusters of severe thunderstorms with…
UPDATE: This threat shifted more to Sunday AM. A Slight Risk is still up for the late afternoon and evening, but severe thunderstorm activity looks to be very isolated. We are temporarily shifting our attention away from Hurricane Isaias, as there are more imminent weather threats in Pennsylvania this weekend. Not only do we…
After many locations across the commonwealth have set records for the hottest July, why not add on another hot and steamy day? Heat Advisories have been issued in southeast PA for indexes up to 105F today, but all of us will be feeling the increased humidity near 60%. Temperatures will remain hot tomorrow, before gradually…
