After 9 days of snow cover - today will be the last and we will have a green Christmas thanks to the Grinch Storm....

How have folks been doing with the wind measurements - if you have other stations how does it compare? Mine is not mounted on the roof yet with my anemometer...so tough to compare so far - thanks! -
Beautiful sunset both in Western Chesco and in Sea Isle City splits were 44.9/35.4 in East Nantmeal and 48.4/38.4 down the shore

With our 10th largest December snowstorm that fell last week on the 16th -17th (9.3") - what does that potentially mean for the ensuing winter snow season? What about December's with a storm greater than 6" during the year's final month?? Funny you should ask below are some statistical potential answers.... -

I think the biggest difference is accuracy in the summer months.....with a fan aspirated shield you don't see the inflated warm readings that so many get siting their stations in the sun....without it you might almost record as many 90+ days as the PHL heat island records.....
-
I think the most accurate is the Vantage Pro2 with the fan aspirated shield - I also have a Vantage Vue / Ambient and the Tempest....but VP2 is in my opinion the best although I just got the Tempest and need to evaluate that one a little more - hope this helps!

With a little bit of elevation on a hill we don't radiate so while a couple miles away down at Marsh Creek lake level (400 ft asl) they have had several lows in the teens ...both here at 685 ft asl and at KMQS Coatesville Airport at 660ft we both had our 1st sub-20 day of the season.

1st Teens of the season this AM and first since February 21st - low was 15.9

Hi Steve! I guess a Christmas miracle is possible...not a big believer in anafront accumlations....but heck - the Christmas magic!! Happy Holidays to you and yours!!

WXSIM has snow arriving about 10am on Sunday morning - some moderate snow by 1pm with a brief period of Heavy Snow by 4pm ending by 530pm with 1" to 2" of snow accumulating....of interest it also predicts that while about 4" of snow will be on the ground on the morning of the 24th....it will all be wiped away before Christmas morning with a 45 degree high and rain.

With the snowstorm total of 9.3" in East Nantmeal Township in Chester County this storm was the 10th largest snowstorm in December history back to 1894 for the county. The 7.3" of snow yesterday set a new daily record eclipsing the 6.0" that fell in 1973. -
Final storm total in East Nantmeal Township in Chester County 9.3" of snow/sleet with 2.0" falling since midnight
-
Back to all snow here in East Nantmeal Twp in NW Chester County temp at 25.5
-
As of midnight the 7.3" of snow/sleet breaks the old daily Chester County PA record of 6.0" set back in 1973...with another 2" of snow from this storm this event could move into the top 10 December Snowstorms in Chester County History dating back to 1894.
-
Heavy Sleet and some snow mixing in here in NW Chesco with the temp down to 25.3 with over 7" of snow and sleet so far....while down the shore in Sea Isle City not a flake of snow so far today with a current temp of 49.0 with our street in SIC flooded but 1.58" of rain so far with a high wind gust of 46mph
-
No model was great with this system including the NAM while it had the warm air at 850mb it totally missed the front end thump....hence why no one model is a forecast
-
Winds are howling up in the trees temp starting to fall again now down to 25.6 with storm total at 10:30 up to 7" of snow/sleet with 5.8" snow and 1.2" IP so far....more still to come....but can we get to double digits??
-
IP has really picked up over last 30 minutes temp now starting back up now at 25.8....just measured another 0.3" of IP bringing our snowfall for the day up to 6.0" - also noting a few mangled snow flakes starting to mix back in over the last few minutes...should see a transition back to snow later tonight from NW to SE....someone will pick up several more inches in wrap around later tonight....not sure where but - nice storm for December!!
-
Certainly possible...remember that 3 to 7" includes sleet which again counts as snow....it just accumulates more slowly...most spots will go back over to snow overnight....so total additional snow/sleet if you get under the wrap around band could get there....
