Hi Jimmy thanks! Where and how did you mount it? How accurate have the IMBY forecasts been? Does it use the EURO as a base forecast? Thanks again!

0.3" of snow in East Nantmeal Township- our 1st measurable snow since the 2.0" on January 18th - December to remember....

Some very light mood flakes continue to fall in East Nantmeal temperature at 36.9

We just missed finishing (in a virtual tie but losing the rounding game) for the Warmest November on record with an average reading of 50.06 vs the all-time record from 1931 of 50.10

The good news is we don't need it to be well below normal cold for it to snow in the winter! I remain confident in my winter forecast of much more snow than last year.....of course that will not be too difficult....if my forecast is accurate we will be 90% to last year's seasonal snowfall by the end of December.

Seasonal Snowfall for Western Chester County PA from 1894 to Present

Of course nowhere close to frost here in the peaks of Western Chesco - only made it down to 34.3 with still only 3 days of 32 or below - which is 11 less than normal through today. Warmest November on the books will do that! On this date back in 1995 we received 3.7" of snow which began the snowy winter of 1995-96 which saw Chesco finish with 81.9" of snow. At the time that was the 2nd snowiest winter exceeded only by 1898-99 when 95.0" fell in the county. We would exceed the 80" mark 2 more times with 86.6" in 2009-10 and 80.0" in 2013-14

Through yesterday this November in Western Chester County PA stands at an average temperature of 50.3. We are a lock now for at least the 2nd warmest November on record. The previous #2 was November 1902 at 49.4 This will be only the 2nd time we have finished a November with an average temperature north of 50 degrees - we have an excellent shot at squeaking out the warmest November ever - eclipsing the 50.1 from back in November 1931. Below are the top 10 warmest Novembers on record and the subsequent seasonal snowfall - 4 of these years (in red) were included in my winter forecast analog package for this upcoming winter.

As part of my website refresh I am going back and updating some analytics etc. I will post here and link on the website. Thanks! 1st off Climate Averages and all-time records for Western Chesco

AM low so far was at midnight at 51.8 - Happy Thanksgiving to all of you and your families!!

Updated chart with revised 90 degree analytics - of note in the last 5 years (2016-20) PHL International Airport has recorded 169 days over 90 degrees....while KMQS / KPTW and East Nantmeal Township combined have seen only 121 such days over same time period. With PHL seeing increasing (+11% ) frequency of 90+ days over the last 8 years.... while the burbs are actually seeing 90+ days decreasing at a rate between 35% to 64% over the last 8 years

Hey guys I have now revised and updated my website at http://www.chescowx.com It now has near live webcam updates, updated historical links, new analytics and for those who kept asking it is now mobile friendly!! I will be continuing to update the site with updated rankings and analytical data of some of my older analysis and also some new and hopefully insightful metrics regarding the inland climate of the philly burbs for the last 127 years for the period 1894 to Present. Please visit and let me know if any suggestions or adds etc. Thanks! Paul http://www.chescowx.com
