PA

While guidance trended less aggressive in terms of the snow side with this powerful nor’easter, there will still be a nice swath of accumulating snowfall from Central PA through Northern PA. We will all begin as rain late Sunday Night/Early Monday Morning, Central PA and Northern PA will begin to change from rain to a mix of sleet/rain to eventually wet snowfall that has the potential to lay down several inches, especially in the highest of elevations. For the rest of us in South-central PA/Southeast PA/East-Central PA, we will be in for a cold soaking and heavy rainfall. Western PA…MORE...
Before we go into the discussion about Saturday’s light snowfall, we are also tracking very mild air that will overspread the state Tomorrow. There is the potential for some areas to reach and/or surpass all-time high temperatures for January 12th. Many locations will reach the middle 50s, with some areas even reaching the lower 60s! Impressive for the middle of January to say the least. GFS model projected high temperatures for Tomorrow: A cold front will then quickly push through the state from the Northwest to the Southeast overnight Thursday and into early Friday Morning. This will lead to more…MORE...
Only slight changes have been made to Tomorrow’s forecast, but overall the general theme remains the same. This will not be a big event. The precipitation that falls Tomorrow will be on the light side and any accumulations of snow and/or ice will be light as well. Timing: Precipitation will begin in Western PA in the mid-morning hours Tomorrow and then around lunchtime for Central and Eastern PA. The precipitation may start off as a brief period of snow, especially farther north in pa, before changing to sleet and freezing rain later in the afternoon. We expect everyone to change…MORE...
We are tracking a system that will produce a light wintry mix for our state on Tuesday. Precipitation will likely start off as snow for the northern two-thirds of the state Tuesday morning, before transitioning to a period of sleet and freezing rain by the afternoon hours. All areas will end in the form of rain by Wednesday morning. Below is the GFS valid Tuesday 7 PM: You can see areas in Western PA have already changed to rain, while Central and Eastern areas are dealing with Snow (blue), Sleet (orange), and Freezing rain (Pink). It is important to know…MORE...
Light snow has officially begun in parts of Western PA this afternoon, and will continue to overspread the state as we progress into the evening hours. Although the snow amounts anticipated will be on the rather light side, timing will be critical. Because it is very cold, the snow that does fall will stick to all surfaces and will quickly add up. Our biggest concern right now is for Southeastern PA where it looks like the snow may linger into the morning rush hour Friday Morning. FINAL CALL FORECAST TONIGHT INTO TOMORROW MORNING Our only big change from our first…MORE...
An area of low pressure tracking just to our south will try to strengthen as it heads off the coast Thursday Night. This puts the entire state on the cold side of the storm, leading to our first true all-snow event, especially for Southern PA. Although the snow amounts anticipated will be on the rather light side, timing will be critical. We are expecting the snow to begin in the mid-afternoon hours out West and by the evening hours in Eastern PA. Because it will be very cold, the snow that does fall will stick to all surfaces and will quickly…MORE...
After a rather warm day across PA Today, it is almost hard to believe in a couple days we will be dealing with a Winter Storm impacting us on Thursday. As we mentioned yesterday, we are watching two areas of low pressure systems this week that will lead to our Winter Storm on Thursday. One will be dropping out of Canada in the form of a weak clipper system, while another area of low pressure develops in the south and eventually heads northeast. Where these two systems merge off the coast on Thursday, will determine how much snow we end…MORE...
We have good news and bad news. The bad news is those who are rooting for a white Christmas this year, will have to wait another year. The good news is, there is no major weather maker in the forecast for the holiday weekend. However, there is a relatively weak system that will impact the state late Friday Night into Saturday Morning. With temperatures marginally cold enough to support snow, we expect there to be rain and snow showers throughout the state during the first half of your Saturday. Areas North of I-80 have the best chance at receiving some…MORE...
OUR SECOND CALL FORECAST FOR THIS WINTER STORM HAS BEEN POSTED, CLICK THIS LINK TO VIEW IT. As many of you know by now, we are tracking a widespread significant Winter Storm that will be impacting the area Friday Night into Saturday. Guidance continues to be in a general consensus for the post part about who will receive what and how much. But, because we are still a couple days away from the storm’s arrival, there is always room for some adjustments. Timing: Snow will overspread the state after 7 PM Friday Evening for Western areas, and then after 10…MORE...
OUR FIRST CALL FORECAST INCLUDING SNOW AND ICE AMOUNTS HAS BEEN POSTED. CLICK HERE TO SEE OUR FIRST CALL While this pattern has been snowy for some, and not so much for others, it sure has been active. As we watch the current radar showing light to moderate snows overspread much of the Western and Central areas of the state this Evening, we are tracking a potential significant Winter Storm Friday Night into Saturday. This upcoming Winter Storm will once again be a Wintry Mix for the region. However, the major difference this time around is, it will be much…MORE...
Before we go into detail about Tomorrow Night’s sneaky snowfall, we are first going to talk about the extremely cold temperatures later in the week. An arctic blast coming from Canada will be in full force beginning Thursday and lasting through Friday. This does not mean Tomorrow and Wednesday will be warm, it simply means we will feel the brunt of the cold Thursday and Friday. Projected High temperatures per the GFS for Thursday: High temperatures are projected to only reach the low 20s in SEPA, Teens over Central PA and Western PA. Far Northern PA and the highest elevations…MORE...
Here we are a little under 48 hours away from our next Winter Storm and model guidance is still all over the place across Pennsylvania for who receives what and how much. But, as weather forecasters, this is one of the many challenges we face quite often and we will give you the forecast the way we see it. With that being said, we are confident that overrunning snow showers will overspread the state during the day Sunday which is well represented by latest NAM model valid 7 AM Sunday Morning:  As the day progresses Sunday, it is quite possible…MORE...
Before we get into the details about Tuesday Evening into Wednesday, a disturbance is still projected to move through the state Tonight and into Tomorrow Morning bringing with it a mix of rain and snow. Our call from last night still stands with this system. If you missed our call, click here>>>http://paweatheraction.com/light-snow-sunday-night-wintry-mix-arrives-mid-week As for the bigger storm potential, we are tracking a Winter Storm set to begin Tuesday Evening and lasting through Wednesday Morning. A low pressure system will develop in the South and track its way Northward before transferring its energy into a coastal low. Over the last 36-48…MORE...
What we thought originally was going to be a sheared out system for Monday, now looks like it will be a snow maker for some, and a rain/snow mix for others beginning late Sunday Night into Monday. Then behind that system, we are tracking a larger storm as we mentioned yesterday, that could produce a more significant amount of rain and/or snow for many areas. First off below is the latest GFS valid 1 AM Monday Morning: Temperatures will be very marginal, so for lower elevations, this might just be a cold rain for you. But areas that do receive…MORE...
Last December was a December to remember in terms of how warm it was, this December will be the complete opposite, as we had expected since the release of our Winter Outlook back on November 1st. And now over the last few days, model guidance is beginning to catch on, and beginning to catch on in a big way. This post will just be focused on the first 10 days of December. If you haven’t already, click here to check out our December forecast>>>December 2016 Forecast After some much needed rainfall the last couple days, our weather is back to normal…MORE...
