Latest Euro....let's hope it pushes a bit further North....also keep an eye on that Storm for Sunday into Monday that for now looks like a southern slider....

Steve I suspect this will be the biggest winter event of the season in these parts....all it takes is one event to get us back to near normal for the year.....

No one else here ever insults others....this is a good friendly site - I don't think he adds much to the site...but just my opinion

Thanks JTA!!

Nice article from the Philly Inky on the differences from Philly to the burbs on snowfall https://www.inquirer.com/philly/blogs/phillylists/Historic-snowfalls-Suburbs-totals-dominate.html

Amen Hurricane A!! it was and still is a silly argument from our LV historian....

Just using a straight 10:1 was not unusual back in the day. What is remarkable is the Coatesville records are so complete. When I first starting analyzing Chester County data back in the late 90's I noticed how many empty observation fields were missing at other long running observation sites like West Chester and Phoenixville (lots of empty snow reporting) . Coatesville has an extremely high % of complete data (all fields) compared to most other sites which makes it excellent for the weather analytics for the County that I enjoy.

I continue to expect a major east coast elevation driven wet snow event - it will no doubt happen when I am in Florida for Phillies (or not) Spring Training the week of March 14

Today was the 17th day with a sub-freezing high temperature here in NW Chester County. This is the most in a winter season since the 18 recorded in 2018-19 season.

Incorrect LV....on the 15th he measured 69.8" on the ground

While we may not have any blizzards on the near-term horizon here in Chester County PA...of interest today back in 1899 marked the end of the largest snowstorm in recorded Chester County history back to 1894. The US Department of Agriculture cooperative weather observer for Coatesville PA was Mr. W.T. Gordon (see his attached hand written observation record below). I gave a talk on this storm a few years back for the East Nantmeal Township Historical Society and it certainly got a reaction! Even more than I think LV Weather Historian gave us back a couple months ago - LOL!! Mr Gordon noted that snow began falling at 7:30pm on February 11th. That day had been a very cold day with the high temperature only reaching 11 degrees above zero...following an AM low of 13 degrees below zero. The following day the 12th featured snow of varying intensity continuing all day. It was a bitterly cold day with the high temperature only reaching 8 degrees above zero after the morning low of just 2 degrees above. Snow accumulated an additional 7.1" during the day of the 12th . The storm then really kicked into high gear on the 13th as the ocean low deepened explosively along the arctic front and moved up the coast - snow and wind increased during the day with winds now out of the northeast across Chester County. By 9pm on the evening of the 13th an astounding 35.3" of snow had fallen during the preceding 24 hours ending at that hour. The snow continued to fall heavily after his last observation at 9pm on the 13th. By the morning of the 14th - the snow had ended but he measured an additional 10" of snow. Bringing the storm total to an incredible 53.0". On the morning of February 15th Mr. Gordon recorded the greatest snow depth in Chester County history when he measured 69.8" of snow on the ground....that's right 5 feet 8 inches of snow were on the ground following the greatest Blizzard in Chester County History on this day back in 1899.

Here in Western Chester County we are at 64% of average snowfall to date through today - 8.7" below our normal through today of 24.4".....the upcoming elevation event in March will be the key to delivering a normal snow season here in the philly burbs!!

Continues to snow and slowly accumulate with a temp down to 29.5 - up to 2.5" here in East Nantmeal

Have picked up another 1/4 inch since this morning - now up to 2.3" for the event - temp down to 30.2

Probably heaviest snow of the event here now in NW Chesco temp at 30.6

Still snowing lightly here in East Nantmeal with 2.0" of snow so far and looks to be picking up again as the radar is filling in a bit - temp at 29.6

1.5" here in East Nantmeal as of 6am - looks like a heavier band working northbound on radar

As of 4am here in East Nantmeal Twp 0.8" of snow and continuing to snow

Some light snow here in East Nantmeal Twp with the temp at 36.9

Correct! Cut it in half...especially 18z runs.....it will come back in line with the 0z runs....

I would cut those NAM amounts in half - I think the NWS has this perfectly - 1" to 3" but would not be surprised at a 4" total in a couple spots.
