PA

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...
Our final snow forecast needed some slight adjustments, mainly to upgrade snow totals over the Laurel Highlands. Currently as of 3 PM the cold front is centered right over Central PA splitting PA in half of two different seasons. Spring in the East and Winter in the West! The cold front will continue to push East, packing a very cold punch along with rain showers changing to snow showers the further West you go. Area A – 6 to 10 inches of snowfall, with isolated amounts up to a foot possible. Blizzard like conditions will be felt at times with…MORE...
Hope you all are enjoying the warm weather while it lasts because we are narrowing in on the details of this season’s first widespread snowfall beginning Tomorrow Afternoon and lasting through Monday. Do not let Tomorrow’s early on temperatures fool you, as it will be very warm to start your day off on your Saturday. Here are the projected temperatures for 2 PM Saturday Afternoon: A very strong cold front is splitting the state about in half. Temperatures ahead of this front will likely reach the mid to upper 60s in many locations. But looking out behind the front, you…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...
THIS FORECAST HAS BEEN UPDATED. CLICK HERE FOR WEDNESDAY’S UPDATE. -Pennsylvania Weather Action Lead Forecaster Josh Adams   We are currently tracking our first potential Winter Storm of the season, that will arrive late Saturday Evening and will last through Sunday. The potential storm system is roughly 100 hours away from impact and there is big time disagreement with our current guidance. Breakdown: A low pressure system will be cutting through the Great Lakes region late this week and will have a trailing cold front along with it. The cold front is our main focus. As we head into the day…MORE...
Say goodbye to the 70s and 80s this week, as by the weekend snow showers will possibly be in the air for some areas throughout Pennsylvania. A strong cold front will be pushing through the region on Friday, delivering with it plenty of rain as we stated in yesterday’s article. This cold front will then transfer its energy off to the coast, where a coastal low will form and head north. As it heads north, wraparound winds from the northwest, will lead to Lake Effect Rain and Snow Showers during the Afternoon and into the Night on Saturday. A second piece…MORE...
