We’re going to kick off Memorial Day Weekend on a stormy tone, with the possibility of severe thunderstorms in eastern and central Pennsylvania. A low pressure system dragging a weak cold front behind it will move north of our area over Ontario Friday. Typically, areas on the southern flank of low pressure systems this time…
Weekends lately have featured anything but nice weather. Last weekend was a torch, and previous weekends featured cool and wet conditions. Memorial Day Weekend last year set the bar very low, as temperatures were in the 40s and 50s as the rain just kept falling. This year, Memorial Day Weekend will be much more pleasant.…
Latest short range model guidance indicates a cluster of thunderstorms developing across Southwest PA late this morning, before strengthening as they head into Central PA by the early afternoon. The cluster of storms is then expected to make its way into Eastern PA by late this afternoon. Damaging winds are the main concern, along with…
It’s been a slow start to severe storm season greatly due to persistent northeast troughing and easterly flow off the ocean promoting a cool, stable environment. But that will change starting this week, as we’ve finally broke away from that stubborn pattern. A cold front will push through as a low pressure moves just to…
If this was January, we would be forecasting a major snowstorm with multiple feet of snow across the heart of the state, but it’s not. Instead, a soggy weekend is expected which is unfortunate because many commencement ceremonies will have to be held indoors on Saturday. Mother’s Day will be mostly dry, with only Western…
A message from PA Weather Action’s sponsor NRG Even though temperatures don’t always seem like it, spring is here. As we often predict, some days we’re able to turn off the heat and open the windows; other days we need the heat to fight off a morning chill. With uncertain weather, it helps to have…
We will continue to warm up today but the progress is gradual, with highs in the 40s and 50s. Mostly sunny skies will be present across the state, working to erase the snow cover in the mountains and get us back to looking like late April. Temperatures may again reach 80 in much of PA…
The Storm Prediction Center has issued a Slight Risk (level 2 out of 5) for the eastern two-thirds of Pennsylvania. Damaging winds are the primary threat, with gusts commonly in the 40-55mph range, isolated higher. A very low hail threat and low tornado threat risk exist as well. Timing for strong to severe thunderstorms will…
This year, March has been a month that made everyone happy weather-wise. We started off warm, even with a bit of severe weather. Then came the snow, dumping over a foot in some areas in the span of five days. Two days later, many of us were flirting with 70 degrees and it’s been very…
A week ago we were forecasting snow. Now we’re forecasting temperatures in the 70s and severe weather. March Madness doesn’t just apply to college basketball, it also applies to our weather this time of year. Coincidentally, Saturday is the last full day of winter! TIMING Scattered low-topped thunderstorms will begin to develop ahead of a…
A rapidly intensifying, but fast moving coastal storm will push up the Atlantic Coast, bringing a period of heavy snow to the state. Timing will vary, as Western PA will see most of its snow tonight, and the eastern two thirds of Pennsylvania will see its snow Saturday morning and early afternoon. This will be…
5:00 PM FRIDAY: Final Call Snowfall Forecast Posted: March weather is known for throwing curveballs, and it does not get any more textbook than starting a week with severe storms and ending is with a near-blizzard conditions. This is not your typical system where the low pressure passes by and cold air wraps in from…
A March daytime snow event with marginal temperatures and a warm ground is the perfect recipe for elevation-dependent snowfall here in Pennsylvania. As a result, higher elevations are likely to see twice the amount of snow as neighboring valleys. This is not our last shot, as we are watching Saturday for probably some interior snowfall.…
FINAL CALL POSTED: After a few days with temperatures in the 60s and 70s, the last thing you expected to be reading about today was snow – in just two days from now. A strong cold front accompanied by a line of severe thunderstorms with potentially damaging winds is making its way east this…
