With yesterday's 7.3" of snow... this November is now the 6th snowiest November in Chester County PA weather Coop history since 1894. Also the snowiest in 65 years - since the 8.6" that fell in 1953. For the snowiest November? you need to go way back to 1898 when 11.4" fell - of interest that winter 1898-99 was also the snowiest winter in history with 95.0" falling

As of 6 am here in East Nantmeal Township in Chester County just light snow now - however, since midnight we have picked up another 1.3" of wet snow with temps just above freezing. This now brings our snowstorm total to 7.3" this now moves this storm past the 7.0" that fell on 11/26/38 into 3rd place all-time for greatest November snowstorms in Chester County history dating back to 1894. Behind only the 9.5" that fell on November 15, 1906 and the 8.6" that fell on November 6, 1953 - mighty impressive event. 

Heavy snow squall been going on the last hour or so here in NW Chesco with some additional accumulations. Will measure when it ends. Just received call schools 2 hour delay - temp 32.9

Still a mix of IP and ZR in NW Chesco here in East Nantmeal up to 6.0" of snow/IP today - tied for 6th largest snow day in November Chester County history

Current temp 30.9

Continues to snow steadily with a mix of IP here in East Nantmeal in Chester County. Another 0.8" since 2:30 pm bringing our total for the day up to 5.8" of snow. This is now the 7th largest daily snowfall in November in Chester County PA  NWS Co-Op history back to 1894. Current temp is 27.2

Still a moderate to heavy mix of snow and IP here in NW Chester County with an even 1" of snow and IP falling in the last hour. This brings our storm total up to 5.0".

This now marks the 2nd largest daily November snow here in the last 36 years here in Chester County-  only eclipsed by the 5.3" that fell just 4 years ago on 11/26/14.  We certainly have a good chance to surpass that mark with the snow and IP continuing to fall. The all-time November snowstorm is safe as we will not be approaching (I think) the 9.5" that fell in the County on this very date back 110 years ago back in 1908

Back to S+ here in NW Chesco temp 27.1

As of 130 now up to 4.0" in East Nantmeal Twp and still heavy snow...sleet now mixing in - temp down to 27.1

Heavy Snow here along with PHL, West Chester, Pottstown and LNS 

We are now up to 2.8" here in East Nantmeal and really coming down. Temp is at 28.1

Up to 1.5" of snow so far here in East Nantmeal in Chester County Temp down to 28.6 with more heavy snow incoming

Moderate to Heavy snow now from York KTHV to Coatesville KMQS - including here in NW Chesco Temp is falling now down to 29.9

I honestly cannot remember a significant November storm in my lifetime(1990-1991) and I've live in the region my entire life(albeit Lancaster and New Jersey for a few years). My memory may be getting fuzzy with old age though  

We had 5.3" of snow just 4 years ago on November 27, 2014 in NW Chesco following 1.5" a couple weeks earlier on the 13th

Wxsim very much into sleet and not much into snow - with up to 2" of snow/IP followed by ZR with temps never getting above freezing here in NW Chesco with 0.1" of ZR

Snow from DC through NY to Boston and expecting rain here, I couldn't have located much worse 

 

 

 

did you move or just visiting somewhere?

Wxsim with 12z GFS/NAM went colder for NW Chesco - now shows temps staying below freezing thru entire event with 1.64" falling - looks like about 0.80" falling as IP. 

The latest 12z Euro Kuchera maps which account for sleet and LL thermals - a little more realistic but IMHO still a bit high...

Continue to think this is mainly a sleet event N and W of Philly...with minimal snow even in burbs at the onset. The dry air drilling in however is impressive - but overrunning will get things going a bit earlier than modeled. With low DPs... temps will fall at onset and be slow to rise...hopefully the cold air gets scoured out before evening rush hour or else it will not be a pretty one out in the philly burbs as we transition to non-solid by late PM. By the way I for one think these early storms bode quite well for an active season with well above normal snowfall. I am working up my local winter forecast for the local paper and think we do a bit better than even last year's 59" of snow out here....just my 2 cents.

reJust glanced at the 6z euro. Caving to the gfs more tucked and warmer solution. Winter of yore or winter of the tease coming? If we put the experimental gfs mid range and euro on lockdown maybe we can avoid the teases.....euro has been bad dating back to 2 seasons with last minute caving and I can already see the new gfs has a cold bias in medium range. 

6z Euro really not much of a cave although the snow totals are ridiculous as it is counting sleet as snow...even EPS has 5" at Coatesville 

Latest Wxsim for NW Chesco with 6z GFS/NAM combo has:

Sleet/Snow mix arriving by 9am tomorrow temp at 30.7

Mod sleet by noon temp 31.3

Heavy Sleet at 2pm temp 31.6 (0.56" of w.e.)

Heavy Sleet/ZR mix at 6pm temp 31.3 (0.86" of w.e.)

ZR at 9pm ending temp 31.7

Plain rain by midnight temp 32.6

Heavy Rain at 3am temp 33.6 (1.40" w.e.)

Back to Heavy Rain/Snow mix at 6am temp 33.8 (1.80" w.e.)

Ends by 7am total precip w.e. 1.92"

Latest Wxsim with 6z GFS/NAM data has snow/IP to start on Thursday AM and then an off and on battle of precip types here in NW Chesco with the temp just above freezing for most of the event + plus over 2" of w.e. falling. This will no doubt change with the next run....by the way also showing a period of heavy snow next Sunday AM...

the 6z Euro has 9" of snow out here at KMQS with the end of week event....that is not likely. My WXSIM has a mix of wintry stuff to start Thursday AM and then over to a chilly rain with a 1/2" to 1" of snow/IP. The pattern does seem to want to keep noreasters forming....will be an interesting winter

Does JB ever forecast anything besides a "December to remember"?

Never ever...has a tremendous cold and stormy bias....but he is still excellent at pattern recognition....
