Another below normal day today across the County...but by Monday we look to start our most sustained heat of the summer to date. It could even be a "heat wave" with 3 or more consecutive days over 90 degrees. Of course while many spots in the county should see multiple days over 90...I suspect East Nantmeal and other relatively higher spots will top out in the upper 80's for the most part....but fingers crossed I can see my first 90+ day in over 2 years!! Records for today: High 102 (1953) / Low 42 (1934) / Rain 2.00" (1959)

Hi Mount Joy No worries! Go to my website at www.chescowx.com for the detailed NWS observer names etc. and site moves across the 9 NM of Chester County during the period of record. The data has been statistically validated with significance testing (p <0.05) across this entire period 1894 to Present. While there have been differences.. slight snowfall increases as expected with the additional small elevation moves...they have been non-statistical as you can see below comparing the lower elevation obs through 1982 vs. the higher elevation obs since 1983. Overall strong consistency in the data over the relatively modest elevation increases across NWS COOP sites over the last 130 years.

So we finished August with our 3rd below normal month in the last 4 months. The maximum temperature we recorded here in East Nantmeal during the month of August was only 83.1 degrees on the 15th. This is the lowest maximum temp for the month of August ever recorded in Chester County. The old low max record was the 84 degree max from August 1927! Here in Chester County we finished the summer months of June through August as the 13th coldest summer (70.3) since records began 130 years ago. If we look at the 4 warm months of May thru August we finished as the 8th coldest (67.3) 4-month spring/summer stretch since 1894. See the table below for both rankings. Rain wise the June-August period was the 27th wettest summer with 17.13" of rain. I will be sure to post the stats for the other long running NWS COOP Chester County sites across the county later today. As cool as it has been this summer...we are about to finally get a taste of summer now that we are starting the first month of autumn. We should see widespread 90+ temps from Monday through Wednesday before we cool down to closer to normal levels by next weekend.

After the overnight showers we should see some great weather through the weekend. We will start below normal temperatures through Saturday....we then start a big warmup that could actually bring the first 90+ day to my station here in East Nantmeal in over 2 years! The last 90+ day was way back on June 30, 2021. In fact we could see a few days in a row over 90 degrees...especially in the lower elevations of the county. Records for today: High 100 (1953) / Low 39 (1986) / Rain 3.40" (1946)

One thing I am telling folks is I guarantee more snow this season than last.....how is that for being bold!!!

Way too small of an n to mean anything...especially with all of the above occurring during our current warming cycle

We picked up 0.53" of rain since last night here in East Nantmeal. More humid today with showers possible through tonight. Clearing for the weekend with lower humidity and back to below normal temperatures by Sunday. Much of the upcoming final week of August looks to be near to below normal. This will result in August finishing with below normal temperatures. In fact this will make 3 of the last 4 months with below normal temperatures. This is the 1st time we have experienced 3 of 4 consecutive months with below normal temps since the 1st 4 months of 2018. Records for today: High 97 (1909) / Low 40 (1927) / Rain 2.45" (1957)

I think C.B. Bucknor gives Angel a run for his money....

Our cooler than normal summer looks to continue as we move toward the end of August. Since June 1st two-thirds or 66% of the days have seen below normal temperatures across Chester County. This upcoming Friday appears to be the only day over the next 7 days to feature above normal readings. Only Thursday looks like a chance of some showers across the area...otherwise dry and cool is the rule. Records for today: High 99 degrees (1916) / Low 44 (1952) / Rain 2.47" (1937)
