We are only running around 80% of normal rainfall for the year to date here in East Nantmeal. It looks like we should see at least some showers and thunderstorms today that could give us some welcome rain. A heat advisory goes into effect tomorrow with highs both Thursday and Friday in the low 90's with increasing humidity. Shower chances will be around both later in the day Thursday and Friday. The weekend looks cooler but still warm before we turn much cooler to start the new work week. Temperatures both Monday and Tuesday may only be in the 70's for high temperatures.

There are some who believe our nightime lows are getting warmer during the summer months. The actual data sees no such warming - almost flat since 1893!

Wonder what is going on at KRDG since 2021?? Further north higher elevation than Phoenixville but now warmer than the Chesco warm spot.

I love when climate zealots simply eliminate stations they deem absurd....LOL!

Temperatures today will be close to average for the date with highs well into the 70's to near 80 degrees. We start a warming trend tomorrow with the peak hot day being on Friday which is the only day that higher elevations have a shot a 90 degrees. Most valley spots should reach the 90's Thursday and Friday including higher humidity. While we will cool by a few degrees over the weekend it will remain hot until Monday when temperatures will fall back toward the middle 80's. We have shower chances tomorrow morning and again both Thursday and Friday afternoon.

Today the PHL Airport looks to record a "heat wave" with their 3rd straight 90+ day. Here in Chesco most spots have not hit 90 degrees over the last few weeks, but we should see many spots do so today. There is a chance of some thunderstorms later this evening that would be welcomed as we continue to run dry across the region. A few degrees cooler tomorrow and several degrees cooler than that on Monday. We start another warming trend on Tuesday and could reach close to 90 degrees again by Thursday.
