7 of the last 10 days have featured below normal temperatures. The next couple days will continue that trend before a warm to near normal over the weekend and slightly above normal temps by next week. We have a good chance to finish in the top 20 coldest May's in Chester County history. If the month ended today it would be the 15th chilliest May on record. Unfortunately, rain chances continue to look slim across most of Chester County with the best chance of any rain being Memorial Day evening. In fact with only 0.21" of rain so far this month we are well on our way to the 2nd dryest May in Chester County history...behind only 1964 that received a paltry 0.14" of rain. Records for today: High 92 (1991) / Low 38 (1926) / Rain 1.92" (1952)

Warming cycle for sure....warming forever - of course not!! just normal cycles!!

It's like a different climate here in Chester County in the last 5 years - most spots almost half as many 90+ days. Maybe the thermometers are too close to the runways?? East Nantmeal (15) / KMQS Coatesville (58) KPTW Pottstown (51) and Glenmoore (88)

It does make a difference but supposedly NOAA adjusts for the UHI problem at PHL See the below stats of 90+ days across all of the NWS Coop spots in Chester County compared to PHL. You can clearly see in reality the number of 90 degrees is declining in the burbs while at the PHL airport they are off to the races. Sad that PHL is viewed as a major climate site with such UHI bias. But don't worry NOAA has taken this into account...

HI Bubble if you do record daily stats I would be very interested to see how you compare to my area here in Chesco - thanks! Paul

Interesting weather fact - Philadelphia International Airport had 22 days over 90 degrees last year in just August and September of last summer. Here in East Nantmeal Township (just 30 NM west of PHL airport )I have recorded 22 days over 90 degrees in the last 10 summers combined!!

Lows this morning 46.5 were running 8 to 10 degrees below normal levels this AM. Those relatively chilly overnights look to continue over the next few nights. Today will feature above normal temps well into the 70's before we cool back down to below normal both Thursday and Friday. A chance of some showers looks to work it's way into the area by Sunday but best chances will be southeast of Chester County. Records for today: High 91 (1964) / Low 30 (1956) / Rain 1.36" (1930)

Sun should be on the increase this afternoon with highs a couple degrees below yesterday and slightly below normal levels for late May. Much of the next week looks to average near to slighly below normal across the area. Best rain chances look like Saturday night through Monday...but it will not be a wash out for outdoor plans over the holiday weekend. Records for today: High 94 (1925) / Low 32 (1963) / Rain 2.02" (1989)

My family bought a satellite dish in the late 80's and it was amazing. Live sporting events without commercials....in between innings Harry Kalas would sing and the cameramen would focus their cameras on girls in the crowd. Live "wild feeds" of all the news networks - fun times!

Today looks to be our only above normal temperature day of the week. Overall temps looks to stay near to slightly below normal as we have a good chance to finish with our 1st below normal temperature month of the year and first since our below normal December 2022. Dry weather all work week but it looks a bit unsettled by the 2nd half of Memorial Day weekend. Records for today: High 95 (1941) / Low 34 (1963) / Rain 2.59" (1915)

Some of the lower and coldest spots like Marsh Creek did briefly hit the freezing mark this morning. Here in East Nantmeal we dropped to 35.9 degrees this is the 3rd coldest May 18th reading since 1894. Only colder were both 1983 and 1973 at 33 degrees. Well below normal temps will continue today before warming to near normal tomorrow. Rain chances increase on Saturday before clearing out on Sunday. Let's hope for some much needed rain as we are now exactly 5" below normal for the year. Records for today: High 95 (1962) / Low 33 (1983/1973) / Rain 2.39" (1988)
