  1. Nearest location is about 80 miles to my SW that reports snow falling is at Raven Rock near Gettysburg at 900 ft ASL Temp here 38.4 DP 27.0 WB 34.0
  2. Today's high temperature of 72.4 was the 2nd warmest March 7th behind only 1921 Top 5 previous below 1921 75 1974 72 2009 70.3 1987 69 1946 67
  3. High so far here in East Nantmeal has been 72.1 - this is our warmest reading since the 72.8 back on October 25th. The record for today may be out of reach at 75.0 set back in 1921
  4. Locations with elevation over 600ft would if these models are correct see accumulation....if below 400 ft - I would think more white rain
  5. Above 600 feet would as modeled see some accumulation
  6. Some accumulating snow starting to look increasingly likely for some areas on Wednesday....all models have something
  7. Here in Chester County. We average almost 6" of snow during the first month of spring. Below is a list of our Top 20 March snowstorms and our top 20 Snowiest March months since our weather records began back in 1894. Of note the snowiest March was just 4 years ago....it has not snowed in March the last 2 years - we have never gone 3 consecutive March years without measurable snow in Chester County PA
  8. Here in Chester County the 2022 - January/February finished with a slightly below average temperature of 30.39. (our 66th coldest of 129 years) Below are the Top 15 coldest January-February pairings - of note 3 of the Top 15 coldest winter month pairings have occurred since 2000. With 7 of the top 15 all taking place since 1977. Rankings below
  9. Unusual but we won't get close to the daily records here in Chester County - Tomorrow and Monday are both record highs of 75 - recorded in 1946 and 1921 respectively
  10. Below is an analysis of the average temperature history by decade of our winter months of December, January and February here in the philly burbs of Western Chester County. As always our climate is very cyclical in it's warming and cooling cycles. By decade we have had 6 decades with increased average temps vs the prior decade and 5 decades with colder temps than the prior decade. Of note the 3 coldest DJF decades occurred during our last cold cycle in the 1960's through the 1980's.
  11. Interesting that as my Facebook weather members has continued to grow....it has been noticed by the powers that be at Facebook! I had no idea that when you reach a certain level of "community significance" LOL - we require more protection. This little side project has far exceeded my expectations and has grown beyond just Chester County. I guess a lot more folks are as Ben Franklin said - "weather wise and not otherwise"
  12. Here in Western Chester County PA the December through February months of 2021-22 ended as the 26th warmest December thru February Period. Of note 17 of these warmest periods have occurred since 1960 - with 13 of these warmest periods prior to 1960.
  13. 31.4 on the VP and 31.3 on the rooftop Tempest Station still steady ZR falling
  14. Most of Chester County is still at or below freezing - temp here in East Nantmeal is 31.4 with more ZR falling
  15. Measured over 0.3" of ice on deck - temp still at 31.5. This is the most ice we have seen in many years here in NW Chesco...
  16. More sleet mixing back in with the ZR here in NW Chesco but....good news is temp is up to 28.1
  17. Temp up to 28.0 let's hope we rise faster than some of the models are showing....steady ZR temp
