ChescoWx

Yes Coatesville NWS COOP and NWS spotter data ....It was actually exactly 32" at Coatesville when obs were taken at 340ft asl from 1894 through 1982. Bumped up a few since observations began at 660 ft asl in 1983

What is seasonal average there? ABE has average to date at about 9" so far with 5.8" recorded to date. I would think ABE seasonal average is close to if not a little above mine at 35.9" here in NW Chesco. Don't think 6" gets them halfway there if my math is good....might not be!!

NW Chesco special - lock it in!!

by the time 925mb temps get to 0c it says 3" of snow has fallen across at least Chesco....not that anything it shows from this distance is likely reality....we wait!!

Hi Steve not from what I see on the NAM....850's never go above 0c from PHL and NW

Special Weather Statement from the NWS 751 AM EST Sun Jan 14 2024 ...DANGEROUS SNOW SQUALLS TO IMPACT THE REGION LATE THIS MORNING INTO THE AFTERNOON HOURS... One or more bands of snow squalls will be moving east at 50 to 55 mph along the leading edge of an arctic airmass, with the potential to impact portions of eastern Pennsylvania and adjacent areas of New Jersey and northern Delaware. Near whiteout conditions and a quick one half inch of snow in just 10 to 15 minutes will lead to dangerous travel conditions as a result of the very poor visibility and snow or ice covered roads. Winds will gust up to 50 mph in the squalls. If possible, delay any travel until the mid to late afternoon hours. If you are traveling, your recognition of these squalls and the actions you take to get off the road or help to gradually slow traffic could prevent a high speed, multi-vehicle accident and save your life and the lives of others. If you see terrain features and objects off in the distance being obscured by heavy snow within the dangerous snow squalls, take quick action to pull off the road to a safe location, such as a parking lot or driveway to wait out the squall. If you are on an interstate, it`s best to get off the road at the nearest exit as soon as you notice the squall to ensure the safety of you and your passengers. If there isn`t an opportunity to safely exit the interstate, slow down gradually, well before entering the squall and turn on your flashing hazard lights.

You have been NAMmed

Tomorrow's potential sweeper event for the more northern folks in the forum....buckle up!!

Actually EURO has nada with the squalls tomorrow....

12z Euro "increases" snow amounts from previous run to 1" to 2" area wide....

Nice model snow week from the GFS.....of course we don't shovel models!!

This upcoming week will be our coldest week so far this decade and in the last 6 years. When the temperature drops below freezing tomorrow afternoon we should see temperatures stay below freezing for at least 7 days. The last time we had a stretch as long as that was the 14 straight days from December 26, 2017 through January 8, 2018. So it's time to lace up those skates to use on the numerous ponds in the area.

We picked up a total rain of 0.94" in East Nantmeal with 0.42" falling since midnight. A cold front is crossing the area this AM and temperatures will be falling through the day. Another cold front sweeps across the area tomorrow and we could see some snow flurries or squall with that and temps will again fall tomorrow PM with temperatures falling through the 20's and into the teens by 8pm. Once temps fall below freezing tomorrow they will stay there for at least an entire week. We will have a few potential light snow events this week with the first one later Monday night into Tuesday morning. The next chance comes in during the day on Friday. Records for today: High 68 (1932) / Low 11 below zero (1912) / Rain 1.34" (1978) / Snow 6.0" (1964)

Is it me or is something wrong with the NWS Mt. Holly Discussion tonight. I don't see temps above freezing after Sunday yet I see the below... LONG TERM /MONDAY NIGHT THROUGH FRIDAY/... High pressure builds across the Deep South Monday night into Tuesday, before shifting across the southeast states and offshore Tuesday night. While the high will not fully build into our region, there will likely be enough of an impact to keep the forecast dry overnight Monday through Tuesday night. High pressure well to our south moves out to sea Wednesday ahead of the next weather system. On Wednesday, an area of low pressure will develop near the Great Lakes region, before shifting toward the Mid Atlantic region Wednesday night. Low-mid level moisture and lift increases as an associated mid level short wave/vorticity impulse moves into the region, which could help lead to showers across the area. By Thursday, this low will become absorbed by a coastal low that is forecast to move northward offshore of the east coast. The majority of the long term guidance keeps the coastal low offshore. This would keep the majority of the precipitation offshore, but there could be some wrap around precipitation as a trough from the previously absorbed low moves across the area during the day Thursday. Temperatures will be cold enough to start out as snow everywhere, before warming and changing to rain for much of the area during the day. High pressure is forecast to briefly build across the southeast states Friday into Saturday, and could impact the Mid Atlantic region, keeping the forecast dry.

I am not sure what you are looking at....but me thinks we have an overall colder than normal peak winter season upcoming between now and the end of February. Now whether that translates to any snow....who knows....it might be like the winter of 1976-77 cold but dry and little snow.

NBM continues the downward snow trend

The EURO joins the GFS in seeing 2 snow events this week with #2 on Friday.....As that well respected met JB says "snow gets layed down and the white carpet is ready for the emperor of the north to ride in on"

Euro came in "snowier"....but not even plowable. Is the trend the Canadian friend?

Canadian with it's model snow cover thinks we get a bit crisp for a while...

ICON and GFS with similar plowable events while the Canadian is indeed SECSy

GFS not too far from the NBM....GFS is in snow pack building mode....storms and rumors of storms incoming!!

Either way are clearly seeing a big pattern change to colder that looks likely to last right through February. This to me looks like one of the more sustained cold patterns we have seen during the heart of winter in some time....
