Looks like we are well on our way with some spots already over an inch....we need it!

We continue our stretch of chillier than normal weather with our 9th straight day with below normal temperatures. The beneficial rainstorm is still on track to arrive overnight tonight and continue well into tomorrow night. The NWS has much of the area receiving 1.5" to 2.0" of needed rain. Tomorrow looks to be the warmest day of the week with temperatures maybe a couple of degrees above average with highs well up into the 50's to near 60 degrees. We turn chillier again over the weekend but dry.

Another morning of freezing temperatures in the valleys and more than a dozen degrees warmer up in the hills of the area. Warwick Township had a low of 25.0 degrees this morning....yet here in East Nantmeal we were exactly 12 degrees warmer at no lower than 37 degrees. Our below normal temperature trend continues through the week with the one exception of Thursday. That day should be near normal temperatures....but with the trade off of rain. This still looks to be the most significant rain for the area since midsummer. Models paint between 1.5" to 2.5" across the area. Behind the storm we turn chillier again but dry for Halloween and the first weekend of November.

With below normal temperatures continuing this week here in Chester County PA to close out October we will finish the month with below normal temperatures. This is the 5th month of the 10 months here in 2025 to feature below normal readings. Overall this will be a Top 50 cool October across 133 years of records. As you can see below this will continue our relative overall actual raw data cooling trend for Octobers since the 1890's.

Some lower spots across the area saw lows in the 20's with Warwick the chilliest spot at 26.4 degrees. Here just a few miles south of there the low was almost 12 degrees warmer at 38.2. We should continue with below normal temperatures for at least the next week. The big weather story will be the beneficial rainstorm that looks likely to arrive by Wednesday evening and continue into Friday morning before clearing out in time for the trick or treaters on Halloween. This could be our most significant general rain event since the end of July. Some models are showing as much as 2 inches for many areas.

Thanks Mike! Great info!!

Hi Mike, Hope all is well! How does Mt.Holly determine the end of the growing season and when to stop issuing frost advisories for a county or zone? Here in Chester County it is tough as most spots below 550 feet have had multiple freezing days and frosts already this month. However, higher spots like around my area we have seen no frosts or freezes. Thanks! Paul

This morning saw quite a few valley spots across the area fall below freezing. Warwick Township our typical cold spot fell to 29.4 degrees. Here just a few miles south but 250 feet higher in East Nantmeal we saw a low of 36.7 degrees this was our chilliest morning since last April 17th when we reached 34.2 degrees. Higher ridge locations have still not experienced a frost or freeze so far this autumn. Our cool autumnal pattern continues this week with the potential of another coastal storm by mid to late week. This storm has the potential to bring some widespread beneficial rains to the area. We will remain with temperatures below normal through next weekend.

Plenty of lows below freezing across most of the valley locations including Nottingham, Warwick Township, West Bradford, West Chester, Devault with the lowest the 29.1 degree reading at Warwick. At our higher ridge spots like here in East Nantmeal we got no lower than 38.9 degrees this morning. Temperatures during the day have been running 5 to 7 degrees below normal during the last couple of days and this chilly trend looks to continue through at least the next week taking us into the first week of November. We stay dry till midweek when we will turn our attention to a possible coastal storm which may impact the region from Wednesday night into Friday.

The NWS has issued a Frost Advisory for tonight for the entire area. However, many spots below 500 ft ASL in Chester County have already seen multiple freezing mornings. Those valley spots may again see freezing temperatures while some higher spots could see some frost but likely staying above freezing. For the rest of October, we should see below normal temperatures with daytime highs falling from the upper 50's today to the low 50's for highs by the start of the new work week. Lows should be frosty most mornings with a widespread freeze possible by next Monday and Tuesday mornings. We stay dry until our next chance of showers on Tuesday night.
