We did drop to 17.6 at 11:59pm last evening moving this Thanksgiving to the 3rd coldest max temp behind only 1903 and 1947. Also yesterday's 30.2 max temp set a new record low max for the date surpassing the 31.0 max temp set back in 1989. Today's AM Low of 13.8 was a couple degrees short of the record low for today which was 11.0 in 1989. We have a chance to set another record low max for the date today which is also 31.0 set back in 1989.

Happy Thanksgiving to All!! Paul

Our high for today will be the 30.2 at midnight making this our 2nd coldest Thanksgiving max temp behind only the 27.0 high from 1996 (records back to 1894) We also reached the teens club for the 1st time with a low of 19.5 - good for coldest Thanksgiving since 2005 and overall our 5th coldest reading on Turkey day passing the 19.9 from Thanksgiving 2000. Good shot we move up in the rankings before midnight the top 4 coldest are: 11/26/1903 - 14.0 11/27/1947 - 17.0 11/24/2005 - 18.8 11/29/1894 - 19.0 Happy Thanksgiving to all!! Paul

As of 11:36 pm local time we are down to 31.0 degrees here in East Nantmeal Township. With the fact that the high temperature for today will be occurring at 12:01 am we have already recorded a tie for the 2nd coldest maximum temperature for Thanksgiving Day here in the County. If we drop another 0.1 degrees over the next 25 minutes... this year would sit alone as the 2nd coldest maximum Thanksgiving Day Temp. The only colder Thanksgiving Day in the last 125 years was back in 1996 when we could only top out at 27.0 for the high temp. We will also have a great chance at a top 5 coldest minimum temperature <19.9 for Thanksgiving Day likely before sunrise tomorrow with an outside chance we eclipse the all-time Thanksgiving Day minimum of 14.0 set back in 1993 by potentially midnight tomorrow night. Much of the day tomorrow will feature temps in the low to mid-20's

Steve....for those that like winter weather and multiple storm chances this pattern over the next month could not be much better...of course this does not mean we get 20" of snow....as we could easily see a storm or two go up west of the apps and a snow to zr to rn event....but me thinks we will see at least 5 chances of wintry precipitation between now and Christmas. Plenty of tracking ahead!

Thanks to my lack of a life on a Saturday Night with 2 grade school age kids...not out and about tonight - I went back and crunched the numbers for Turkey Day in Chester County Pa. This was not as easy as some analysis as Thanksgiving falling on the 4th Thursday of November is not conducive to standard excel pivot tables that I normally use but here are the weather facts for Thanksgivings in Chester County Pa during the last 125 years of CoOp history since 1894. Highest Temps on Thanksgiving Day 1 - 11/30/1933 - 72.0 2- 11/26/1896 - 70.0 3 - 11/22/2007 - 68.9 4 - 11/22/1979 - 68.0 5 - 11/26/1914 - 67.0 Lowest Temps on Thanksgiving Day 1 - 11/26/1903 - 14.0 2 - 11/27/1947 - 17.0 3 - 11/24/2005 - 18.8 4 - 11/23/2000 - 19.9 5 - 11/29/1894 - 19.0 Lowest Max Temp on Thanksgiving Day 1. 11/28/1996 - 27.0 2. 11/27/1930 - 31.0 3. 11/23/2000 - 32.9 4. 11/28/1901 - 34.0 5. 11/27/1958 - 35.0 Most Snow on Thanksgiving Day 1. 11/24/1898 - 3.2" 2. 11/23/1989 - 2.8" 3. 11/24/2005 - 1.6" 4. 11/28/1901 - 1.2" 5. 11/25/1909 - 1.0"

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

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

Snow starting to mix in with the light sleet here in NW Chesco Temp 30.8 DP 21

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

where are you? are you there for the winter??

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...
