ChescoWx

Indeed!! Chester County has only had 14 seasons or 11% of the time (1972-3 had no snow at all) where the 1st snow occurred in January. Historically, 89% of the time the 1st snow occurs before New Year's Day. Only 1 year - 2016 ever recorded their 1st snowfall of the year in January and ended the season with above normal (36" annually for Chesco) Below are the 14 years with the first snow in January and the seasonal snow totals. Average snow in those years was only 19.9" or 55% of normal seasonal snow First Snow in January # Year Snowfall 1 1942 9.0 2 1944 18.7 3 1949 20.9 4 1957 12.3 5 1966 34.6 6 1972 19.8 7 1975 14.5 8 1976 19.0 9 1980 12.8 10 1992 9.5 11 2000 29.7 12 2002 11.1 13 2007 25.3 14 2016 40.8 Average 19.9

yep not 1 but 2 fantasy storms.....

GFS doing swell this year so far....here is it's model run for between Christmas and NY Eve morning

For those who like snow....I always say bring the cold and the snow shall follow....

Today's high in NW Chester County was 59.1 this was the warmest December 16 since the 64 back in 1975 - the all-time record high for the date is the 67 back in 1971

Sounds close to Coatesville....just always seems to snow a little more in Western Chesco than the Lehigh Valley

Here in Western Chester County PA - top 5 early December Snowstorms 12/14/1917 - 14.5" 12/6/2003 - 12.5" 12/4/1957 - 12.0" 12/7/1910 - 10.9" 12/5/2002 - 9.0"

No record high so far here in Chesco "only" made it to 62.4 (record is 68 in 1897) - though close to just 6 years ago when on this date in 2015 we hit 63.1. High wind gust so far today 30.2 mph on Tempest and 24 mph on the Vantage Pro with .05" of rain so far

Up to 53.6 here in NW Chesco - high wind gust 16 mph so far on VP and 15.6 mph on the Tempest

The overnight GFS does indeed show the turn to colder by next Sunday and for now models a snowstorm during Christmas week - of course this will change 50x over the next 10 days....but something to keep an eye on

Now before our LV friend says all of the data is invalid blah blah....I of course have never used or presented any other Chester County sites for my data analytics or weather website ever until we started this fun little thread. I have for the last 23 years focused entirely only on Coatesville PA weather data as it represents the ONLY complete data set from 1894 and updated through today for ALL weather parameters and has zero gaps in any observation data. I have never done any QC on the other sites in the County and simply reported them on this thread to corroborate analysis for Coatesville which I have done in this thread - even though LV doesn't like it.

Yep it looks like the NCDC has faulty data for West Chester for April 1895. See below - it looks like they simply calculated all falling precipitation as snow and of course no other station in the county reported any snow that month.

Tomorrow will see near record high temps for December 11th - so below is a list of record high temperatures for NWS Coop sites across Chester County and the year it occurred Coatesville - 68 (1897) / West Chester - 67 (1966) / Phoenixville - 66 (1966) / Chaddsford - 65 (1971)/ Glenmoore - 64 (1971) / Honey Brook - 64 (1971) / Devault - 62 (1897)

Can't delete factual history that has been in existence for over 100 years because you dislike the facts.....just sayin

Below are the Top 10 snowstorms and the location that reported the snow totals across all National Weather Service Cooperative (COOP) locations in Chester County PA since record keeping began back in 1893

Hey LVwxHist guy - to help get you back on track away from this strange historical snow witch hunt....since you are the LV wx guy - post some actual stats for the Lehigh Valley and we can see how different the weather is from there vs. Chester County PA. For starts why don't you post the top 20 snowstorms for the LV and we can compare and contrast against all of the Chesco sites - thanks!!

Indeed!! you can't change history....but in our current cancel culture - sadly they may indeed cancel history if it does not meet the narrative....strange times we live in....enough of that crap - now back to the weather!!

LOL except your every snow total inflation story for Coatesville....kind of fell apart like 70 times!!

Just to clarify those are daily snowfall totals - I failed to include the actual days of the month (see updated below). - those are 70 daily snow observations that Coatesville's observer reported less than West Chester - It appears clear the April 8. 1895 number out of West Chester is wrong - in fact a bunch of the 1895 WC obs look a bit off.... # Year Month Day CV Snow WC Snow 1 1895 April 8 20.9 2 1909 December 25 13 13.5 3 1895 February 8 10 13.3 4 1895 April 13 8.8 5 1895 February 21 2 7.5 6 1898 November 26 4.5 6 7 1903 February 16 5 6 8 1904 December 10 5.9 6 9 1899 February 7 3.3 5.5 10 1904 November 13 5 5.5 11 1899 January 1 0 5 12 1904 February 19 4 4.5 13 1904 December 25 4.4 4.5 14 1896 March 11 4 4.3 15 1894 April 9 0 4.1 16 1895 April 2 4.1 17 1903 December 3 2.2 4 18 1908 January 24 3.5 4 19 1908 December 23 2.8 4 20 1894 February 25 3 3.5 21 1904 March 14 2.4 3.5 22 1905 December 15 2.5 3.5 23 1899 January 31 3 3.3 24 1896 March 15 2 3 25 1896 December 16 2.5 3 26 1898 November 27 0.5 3 27 1907 February 1 2 3 28 1908 January 23 2.5 3 29 1894 February 22 2 2.8 30 1895 January 29 2.5 2.8 31 1907 January 17 2.7 2.8 32 1895 January 28 2 2.5 33 1902 January 29 1.8 2.5 34 1897 January 15 2 2.3 35 1901 November 29 2.1 2.3 36 1907 December 4 0.7 2.3 37 1898 November 30 1.1 2 38 1900 January 1 1.5 2 39 1901 January 30 1.5 2 40 1903 January 25 1.2 2 41 1907 November 24 1 2 42 1909 January 17 1.5 2 43 1896 February 19 1.8 44 1902 February 22 1.4 1.8 45 1906 January 8 1.7 1.8 46 1907 January 26 1.5 1.8 47 1895 April 1 1.6 48 1909 February 3 0.6 1.5 49 1909 March 6 1.3 1.5 50 1901 December 23 1.2 1.3 51 1902 January 30 0.7 1.3 52 1904 December 12 0.3 1 53 1907 February 10 0.5 1 54 1904 February 27 0.6 0.8 55 1907 January 27 0.5 0.8 56 1907 January 29 0 0.8 57 1907 January 30 0 0.8 58 1908 December 11 0.5 0.8 59 1909 January 7 0.5 0.8 60 1909 December 13 0.5 0.8 61 1904 February 26 0.3 0.5 62 1907 December 18 0.2 0.5 63 1904 December 13 0 0.3 64 1904 December 15 0.0001 0.3 65 1909 January 8 0.2 0.3 66 1909 January 29 0.2 0.3 67 1895 April 3 0.2 68 1908 December 13 0.1 0.2 69 1909 March 30 0 0.2 70 1909 March 25 0 0.1

LV you just keep on back pedaling - now it's only the big storms but he is a good reporter for small storms.....LOL!! All 70 times Coatesville reported less than West Chester are detailed below,,,,and this is only over a short 15 year period - that you said was for every snowfall.....weak!!!! # Year Month NWS WC COOP 1 1895 April 20.9 2 1909 December 13.5 3 1895 February 13.3 4 1895 April 8.8 5 1895 February 7.5 6 1898 November 6 7 1903 February 6 8 1904 December 6 9 1899 February 5.5 10 1904 November 5.5 11 1899 January 5 12 1904 February 4.5 13 1904 December 4.5 14 1896 March 4.3 15 1894 April 4.1 16 1895 April 4.1 17 1903 December 4 18 1908 January 4 19 1908 December 4 20 1894 February 3.5 21 1904 March 3.5 22 1905 December 3.5 23 1899 January 3.3 24 1896 March 3 25 1896 December 3 26 1898 November 3 27 1907 February 3 28 1908 January 3 29 1894 February 2.8 30 1895 January 2.8 31 1907 January 2.8 32 1895 January 2.5 33 1902 January 2.5 34 1897 January 2.3 35 1901 November 2.3 36 1907 December 2.3 37 1898 November 2 38 1900 January 2 39 1901 January 2 40 1903 January 2 41 1907 November 2 42 1909 January 2 43 1896 February 1.8 44 1902 February 1.8 45 1906 January 1.8 46 1907 January 1.8 47 1895 April 1.6 48 1909 February 1.5 49 1909 March 1.5 50 1901 December 1.3 51 1902 January 1.3 52 1904 December 1 53 1907 February 1 54 1904 February 0.8 55 1907 January 0.8 56 1907 January 0.8 57 1907 January 0.8 58 1908 December 0.8 59 1909 January 0.8 60 1909 December 0.8 61 1904 February 0.5 62 1907 December 0.5 63 1904 December 0.3 64 1904 December 0.3 65 1909 January 0.3 66 1909 January 0.3 67 1895 April 0.2 68 1908 December 0.2 69 1909 March 0.2 70 1909 March 0.1

Our "heaviest" snow of the day here along the peaks of the Welsh Mountain!! I saw multiple flakes!!

Most reliable IMHO and relatively affordable model is the Vantage Vue....although I do like the Tempest with no moving parts etc.

Now you say "not that it really matters" after saying Coatesville totals were inflated every time and now proven wrong not once.....but 70 times in the period you assured us was each and every time. You should stick to your LV history - your story and goalposts seem to keep changing LOL!! Do you have any good history to share with us about the LV or just call folks names??
