First Call

We are now under 30 hours away from a significant winter storm impacting regions of the state that have so far had little snowfall. Winter Storm watches are currently being hoisted across eastern pa and just about all of south-central pa. This will be our largest winter storm of the season so far, given how many of us will be impacted by a significant amount of snow. The trend over the last 24 hours with guidance has leaned pretty similar to our #1 scenario last night. However, guidance has trended wetter (snowier) and also a stronger system in general. For…MORE...
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...
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...
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...
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...
After what will be a warm Friday and Saturday, it will be hard to believe our first widespread snow event of the year will arrive late Saturday Evening and continue through Sunday and even into some of your Monday especially for Northern areas. A cold front will sleep through the area during the day Saturday, dropping temperatures from 50s and 60s in the early part of the day, to 30s and 40s by the evening hours. From here, it is expected that a low pressure system develops along the front once it reaches the coastline, which will then allow for…MORE...
FIRST CALL FOR TUESDAY NIGHT INTO WEDNESDAY’S STORM, TIMING & AMOUNTS INCLUDED As we mentioned yesterday, the Winter Storm threat to the state that will be impacting us late Tuesday into Wednesday, will be a rain maker for most locations. However, Northwest PA and the Laurel Highlands will have a chance at seeing accumulating snowfall. A low pressure will gather its energy and slowly strengthen over Southern Ohio before tracking through Central PA. Unfortunately, for snow lovers, this puts most of us on the warm side of the low pressure system. As this low pressure heads off toward the Northeast, it will begin to rapidly strengthen and deliver a much more significant…MORE...
