Thunderstorms are expected to pop-up early this afternoon over the northern PA mountains and push southeast in the mid to late afternoon. At the same time, the wildfire smoke will also be pushing southeast, as illustrated in the map at the bottom of the post. The Philadelphia Area has the greatest risk of scattered severe…
July has gotten off to an incredible start in parts of Pennsylvania rainfall-wise, with northeast Philadelphia suburbs already over a foot of rain in two weeks. Many other areas have seen 3-7″ of rain. Nearly the entire state is well above average so far this July with the exception of south of Route 30. Check…
Believe it or not, we have rounded the bend in severe weather season and at the end of the peak. Sunday was a very active day with many tornado warnings and severe thunderstorm warnings. No tornadoes have yet been confirmed, but widespread wind damage took place across mainly central Pennsylvania. Now with more hot and…
A broken line of storms is expected to form out in front of a weak cold front sweeping through the region. Timing for this line is actually quite different than what we normally see, and this time storms are likely to form across western PA, and drift southeast into central PA. STORM TIMING Expect storms…
Scattered thunderstorms are expected to form ahead of a weak front Thursday afternoon, especially across the eastern half of the state. However, all of the state except NWPA has been added to the Marginal Risk, accompanied by the expanded Slight Risk. Morning scattered rain showers and cloud cover does create some uncertainty as to when…
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…
Wow has it been dry lately! The high pressure responsible for the dry stretch is finally exiting the area, and rain chances are finally in sight. We are not expecting much out of today’s marginal risk besides a few isolated storms in northeast Pennsylvania this afternoon and evening. Only a low wind risk exists with…
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. Mostly sunny skies are expected overhead today, and partly cloudy skies are likely Saturday and Sunday. A few spotty showers/storms are possible Saturday afternoon and…
Temperatures are rapidly rising as a very tall ridge will work as a heat-pump, bringing in high temperatures 10 to 20 degrees above average in a few days. We expect to come within 3 to 5 degrees of record-highs, but do not anticipate anywhere around the state will break records. With any threat of precipitation…
So far, this May has been on the cool side, which has resulted in a delayed start to thunderstorm season not only across PA, but across the entire country. That all looks to change though as we head into the coming few weeks, with temperatures quickly rising this week. Many of us will easily climb…
Scattered showers are likely in western PA this morning before the rain shifts into central PA by the afternoon. Locally heavy downpours are expected across the Laurel Highlands and Southcentral PA mid to late this afternoon. A quick half-inch to inch of rain looks possible in those areas. Temperatures will also rapidly fall about 10…
A warm and humid day is on tap, and unlike yesterday, we expect some sun to break out by the late morning. Scattered showers and thunderstorms are expected to pop-up by mid to late afternoon, however there is a low chance of severe activity. The Storm Prediction Center has issued a Marginal Risk for today…
We are in that period in between winter weather and severe storms where there sometimes isn’t much to talk about weather-wise, but Wednesday looks to potentially bring a little of both to Pennsylvania. In typical fashion for late April, the snow will fall across northwestern PA, and our line of heavy showers will be in…
One of the snowiest winters in a while is finally coming to a close as one last deep trough moves in, dropping temperatures 10-15 degrees below normal for Thursday and Friday. Scattered snow showers, some of which may be heavy, are expected in northern and western Pennsylvania late this afternoon into the evening. Wind chills…
