ChescoWx

If you like a big east coast storm - I like it to be out to sea at this range. I suspect it starts coming back on most models by 0z tomorrow night

Cloudy Temp 23.6 RH 48% DP 7.3....some virga in the area

Latest NAM still liking the "peaks" of the Welsh Mountain anticline here in Chester and Berks Counties

Through yesterday we are at 40% of our normal seasonal snow to date here in NW Chester County. If the models are correct we may get pretty close to normal seasonal snow to date over the next 6 days. Of course we don't shovel models! Some southern areas of Chesco could see some flurries later today but for most snow will hold off till after the 7pm hour. The NWS is forecasting 2" to possibly 4" across the area by the time the snow ends tomorrow morning. Sun returns Wednesday before our next chance of snow arrives on Thursday night. Temperatures for the next week will remain below freezing. Records for today: High 70 (1932) / Low 3 below (1988) / Rain 1.07" (1898) / Snow 6.0" (1927)

NAM does show that warm layer nosing in all the way up to the city....something to watch

12z NAM has a solid 2" to 3" across much of the area by the time the birds game ends,,,,more still to fall

I never understand this bizarre take....if our team sucks as this team sure seems to...why do I care what the cowgirls do??? I have zero interest in their ineptitude!!! I

18z GFS with the next one being another Chesco special.....me thinks not!!

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.

Latest NAM

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)
