ChescoWx

Most spots exceeded the 90 degree mark yesterday across Chesco...exceptions being KMQS Coatesville Airport and of course here in East Nantmeal where 86.8 was the best we could do. My Ambient model station only made it to 86.2 (although my rooftop station did hit 90.9). It appears most spots will not hit 90 degrees today. In fact looking ahead it appears yesterday may have been our last 90 degree day for the summer. It looks like here in East Nantmeal we will fail to have reached 90 degrees in summer for the first time since 2015 and for the 4th time in the last 20 years! The other years we failed to touch 90 degrees were 2004, and 2014. More thunderstorms are possible tonight as sharp cold front approaches and moves through the County. Some incredibly comfortable weather moves in this week with most days featuring highs in the 70's and lows in the 50's - a chance to give the AC a break!! Records for today: High 101 (1901) / Low 47 (1956) / Rain 2.48" (1976)

Most spots were well into the 80's yesterday for high temps with even some 90's in lower spots of the county. Today it appears almost all of us...will reach the low to mid-90's. Now, my location here in East Nantmeal has failed to actually surpass the 90 degree mark for more than 2 years! The last time I recorded a over 90 degree temperature was way back on June 30, 2021. That said I do have a poorly sited roof thermometer that has hit the 90 degree mark 2 times this year....but that roof top location inflates the readings. Correct placement of a thermometer is 4.5 to 6 feet above the ground and in a grassy location. It looks like showers tomorrow night will end this brief heat spell with yet another below normal stretch of weather days ahead starting Sunday through much of the upcoming week. Records for today: High 101 (1941) / Low 50 (1946) / Rain 3.47" (1914)

Yesterday was our 10th straight below normal day. That changes today as a very brief potential heat wave impacts the area today through Saturday. The peak heat will be tomorrow PM when most spots in the county should touch the mid 90's. Much cooler weather returns by Sunday with another stretch of below normal temps including most nights reaching the 50's for lows. Records for today: High 99 (1940) / Low 48 (1946) / Rain 2.23" (1966)

A wide range of rain totals across the County yesterday with as little as 0.12" in Chadds Ford to near 4" in Central and Eastern sections. We should top out short of 90 degrees today across most of the county but Thursday through Saturday we should see temps in the lower 90's for most. The heat will only pay a brief visit as has been the case this cool summer with temps likely not escaping the 70's by Sunday. Records for today: High 99 (1940) / Low 48 (1977) / Rain 1.64" (1994)

This does not look very warm to my eyes despite the alarmist talk of never before seen high temperature heat....

16 of our last 21 days here in July have been running with below average temperatures. That will change as the next 5 days should see temps running above normal. We could see some showers this afternoon and early evening. The heat really starts to build in by Thursday with many spots in the county touching the 90 degree mark. By Thursday and Friday even the ridge areas should see a rare 90 degree reading. Below normal temps look to return again by Sunday. Records for today: High 96 (1921) / Low 47 (1976) / Rain 2.00" (1916)

Some showers moved across Southern Chester County this AM with some additional showers possible through later this PM. Our temperatures should rise to near normal for the first time in over a week. Our chances for a heat wave for Chesco appear to be fading as it appears we may just miss 90 on Wednesday especially across the relatively higher terrain. However, both Thursday and Friday should exceed 90 before we cool back to near normal by the end of next weekend. Records for today: High 95 (1918) / Low 48 (1985) / Rain 1.23" (1911)

Morning lows were again below average today with many lower elevation spots reaching the 50's again. Today will be our 7th straight (but last) below normal day with highs topping out in the low to mid 80's. Temps should reach the 90's starting Wednesday for many areas in the county. In fact we could see our first "heat wave" (3 consecutive days over 90) since July 19-21, 2020. In fact in the last 20 years we have only recorded 10 "heat waves" in total here in Chesco! This heat will be short lived as the pattern will shift again by next weekend and we look to go back to near normal to below pattern through the first 10 days of August. Records for today: High 98 (1991) / Low 51 (1983) / Rain 4.04" (1946)

Some valley locations like Marsh Creek bottomed out at 59.8 this AM only 62.9 here in East Nantmeal. Today will be our 6th straight below normal temperature day. This cool streak looks to continue until Tuesday. By mid week we will see a big warmup with a great chance that even East Nantmeal and the ridge locations in the county may see their 1st 90 degree day in over 2 years! Friday looks like it may be the peak heat day. So enjoy the great weather this weekend!

After our 0.65" of rain this morning we are now all the way back to 95% of normal year to date rainfall through today. A top 10 weather weekend on the way with sunny skies slightly below normal temps and relatively low humidity. A slow warming trend starts next week and we could see our 1st 90+ day here in East Nantmeal for the first time in more than 2 years by the end of the week!
