If you thought this August was chilly across the Philly burbs of Chester County PA it indeed was. We finished with the 6th chilliest August in 133 years of data back to 1893.

Despite a well below normal August in temperatures overall summer (June thru August) finished as our warmest summer since 2010. But still well below our warmest summer way back in 1943. Overall there has been clearly almost no warming at all across our summers since 1893. A very flat trend line is clear to see! The below analysis is across 31 NWS/FAA/DEOS/COOP and trained spotter data since 1893.

We will end August as one of our driest last full months of summer in our climate history. We will also finish with our 4th below normal temperature month across the first 8 months of 2025. Our beautiful weather will continue through the holiday weekend and well into the new work week. We may finally see some beneficial rains by Thursday night into Friday. Thursday looks to be the warmest day of the week with some spots possibly exceeding 80 degrees. We will get cooler again by next weekend.

Lows were in the 40's across much of the area this morning with the lowest being the 41.6 at Warwick. Of note the low this morning at East Nantmeal was 49.2 - this is the first time in my 22 years of weather observations that I recorded a temperature in August in the 40's! Expect many areas to again see lows by Sunday morning in those same chilly 40's. Beautiful but dry weather continues through the holiday weekend and through at least Wednesday. There is a chance of some much-needed rain by Thursday...fingers and toes crossed!

Our run of dry and unseasonably cool weather looks to continue through at least the next week. Another cold front is crossing the area today and by later today winds will turn to the west, northwest, and become gusty. Dew points will fall into the 40's by evening and actual air temperatures will likely follow with widespread lows by Saturday morning in the chilly 40's. Some of our usual colder lower valley spots may be in the low 40's with even some 30's not out of the question. Some higher spots may not escape the 60's for highs tomorrow afternoon. Rain chances look low for much of the week before some chances of rain creeping back into the forecast by Thursday.

I suspect we are likely done with any more 90 plus days this year. Over at the PHL Airport they saw an above average of 36 such days.....here in Chester County a bit different story. We don't have our usual NWS COOP hot spots (Phoenixville and Spring City) reporting yet but below are current available stations with their 90+ days so far this year vs. each station's average number of such days.

@TimBhas a few "issues" and banners he needs to carry so I just ignore him....

I have calculated the ending average temperature for here in East Nantmeal Township using the current NWS Forecast. If the forecast temperatures verify - this will be the chilliest August since my records begin here from back in 2004 across 22 years of data. -

Of note that 45.9 degree low temperature this morning at Warwick Township is the 2nd coldest temperature recorded in the county on this date behind only the 42 degree low back in 1944 at Phoenixville.

This morning was our chilliest morning of the late summer/early fall season. Many of the area lower valley spots fell into the mid to upper 40's including Warwick Township at 45.9 / Nottingham 47.0 / Avondale 49.5 / Kennett Square 48.7 / West Bradford 47.8. The higher ridge locations stayed in the lower 50's. We should see a repeat with similar temperatures tonight. Our below normal temperatures will continue through the week and into next week. The "mildest" day looks to be tomorrow, but it will still feature temperatures still several degrees below normal for the end of August. Another cold front crosses the area tomorrow night and we should again see nights in the 40's for those valley locations both Saturday and Sunday morning. Only a very slight chance of a shower on Friday otherwise another dry week in what has been one of our driest August months on record. -

Thanks Mount Joy!!

Unfortunately, the cold front passed with nothing more than some drizzle in spots. The good news is that likely the best weather week of the year is underway! Today will be the warmest day but not too far from average for the date. Tonight we fall into the 50's for lows which will continue each night for at least the next week. I suspect by Thursday and Friday morning we may see some of our chillier valley locations fall into the 40's. Highs throughout the week will be in the low to mid 70's with low humidity. Enjoy!

Today will be the warmest and somewhat humid day for the rest of August. A couple showers are possible late today and tonight with a cold front. Here in East Nantmeal we could really use the rain as we are well on the way to finishing this August as the driest such month since I began keeping records in 2004. So far I have only measured a scant 0.19" in August. The previous low month was back in 2005 when only 1.24" fell. This next week may be one of the best weather weeks of the year! Autumnal weather with low humidity and unseasonably cool temperatures for the final week of August. Highs on Wednesday will struggle to escape the 60's for high temperatures across the higher ridge areas. Highs for the week will be mainly in the low to mid 70's with nights well down into the 50's with some 40's possible in valley locations.
