I noticed that our local channel 6 weather team over in Philadelphia has been posting how since 1970 springs are getting warmer....as is always the case they only seem to look at since 1970. Why is that a problem? A quick look (see below) at the 3 major NWS COOP sites here in Chester County PA show that by starting the analysis in 1970 the data is clearly skewed because overall the 1960's was the decade with the coolest readings. The warmest springs here in Chester County averaged over the 3 long term sites actually occurred back in the 1940's. Only focusing on 50 years does not prove a trend.

Yesterday was our warmest day since the 84.3 degree reading back on September 4th. We should be a couple degrees cooler today with clouds increasing later. Some showers toward morning tomorrow ending by late Saturday night. Some spots could see 0.25" to 0.50" of much needed rain for the county farmers and green thumbs! Records for today: High 88 (1941) / Low 22 (1940) / Rain 2.28" (1970) / Snow 2.5" (1923)

We set another record low maximum this morning with a low of only 61.2 - breaking the old record of 59.4 set in 2019. Today will be the warmest day of the week as temps could approach near record levels this PM. A little cooler but still over 80 degrees tomorrow before we start a cool down over the weekend along with the chance of some much needed showers. Records for today: High 86 (1977) / Low 21 (1975) / Rain 2.40"

Maybe some below normal spring days in our future if GFS is to be believed

Well it is likely we are finished with any snow this season here in Chester County PA. This season ended up being our 3rd least snowy winter since records began back in 1888. Below are the top 20 least and most snowy winters. Note that 6 of our snowiest seasons have occurred since 2000 - while only 4 of our least snowy seasons have taken place since 2000.
