  1. Below is an analysis of the number of days with below freezing minimum temperatures by month and observing station for here in Chester County PA. Most locations with the exception of the highest spots will typically see their 1st sub 32 degree reading here in October. We already have seen the first freezing temperature this week at Warwick.

  3. A good 10 degree spread in low temps this morning - with lower spots in the lower 40's like Warwick and low 50's in higher spots like KMQS and East Nantmeal. The NWS has highs today and tomorrow in the mid-70's - I suspect today may generally be around 70 with the mid-70's holding off till tomorrow. Cold front sweeps thru tomorrow night with some slight shower chances. This will usher in our coldest weather of the early fall season to date. Highs will remain below normal through the rest of the week.

  5. Here in Chester County we saw our first subfreezing low of the season with the 31.9 degree reading at Warwick. Several of the lower spots in the County were in the 33 to 34 degree range so some likely frost in many areas under 450 feet ASL. Most of the higher spots remained in the low 40's like the 40.1 degree reading in East Nantmeal. Another below normal day before a big warmup for the weekend followed by a chill down that lasts all of next week. Highs next week will likely remain in the 50's for high temperatures in the higher spots with no higher than the low 60's in lower locales. We should also see some additional frost or freeze chances by next Tuesday and Wednesday mornings.

  7. This morning was our chilliest morning 42.9 degrees here in East Nantmeal since last May 11th (41.7). Lower spots of Chester County like Warwick saw a low of 34.8 degrees this morning. There is a frost advisory for tonight and some lower spots may actually reach near or slightly below freezing by tomorrow AM. Higher spots like here in EN should stay well above freezing and frost levels. Higher spots will struggle to escape the 50's today with low 60's across lower locales. We turn warmer for the weekend before we again chill down to start the new work week. We should see more freeze and frost potential by next Wednesday morning. Our only slight rain chance looks to be Sunday night.

  9. Some spots including Warwick Twp. dropped into the 30's (38.7) this morning. Dry and cool weather continues over the next couple days highs tomorrow will struggle to escape the 50's in the higher spots with even some frost possible in the lower spots by Friday morning. We warm to a little above normal this weekend before falling back to well below to start the new work week. We may see more widespread frost by next Wednesday morning or so. Of note today in 1979 marks the start of the earliest recorded snow event in Chester County with the 1" at Morgantown/Elverson and 3" recorded on the 10th at Devault. Growing up in Northeast Philadelphia I remember this event as we received a coating there and it was the earliest I ever saw snow.

  11. A stretch of below normal temps looks likely for most of the next week. With highs in the mid 60's most day's with the exception of our one mild day on Saturday when high temps could touch the 70's. The chilliest air of the early fall season then looks to arrive next Monday with highs struggling to escape the 50's in some of the higher spots of Chester County. Sadly, about our only shot of rain looks to be Sunday night with a cold front.

  13. A little tired today as I was at last night's game. Go Philies!! Weather wise here in Chesco - a dry week (as usual) and turning chillier than normal for early October with even some 30's possible for lows by Friday morning. Temps closer to normal by next weekend.

  15. 41.4 at Warwick was lowest temp I could find in Chesco this AM. Today looks like our last 70 degree day till next Saturday. A cold front sweeps across the area toward tomorrow morning with the chance of a shower. After tomorrow AM it again looks like a dry week.

  19. Happy Red October Phillies Day to those who celebrate!!! Go Phillies! A beautiful stretch of autumnal weather on the way with both today and tomorrow reaching above normal high temps in the low 70's before we chill down to well below average highs starting on Monday and thru the rest of the week. Nigh time lows starting tonight will be in the 40's and maybe some 30's by Wednesday morning. Some shower chances increase by Sunday night with a cold frontal passage - otherwise a dry week.

  21. With autumn upon us I thought I would look at the average first freeze along with earliest and latest occurrence across Chester County PA at all 31 available stations. As you might expect the relative lower elevations experience freezes and the end of the growing season about 6 days earlier compared to the somewhat higher spots. There is great variability across the years with the earliest recorded freeze being at Phoenixville on September 17, 1986 and the latest being over 2 months later at Devault 1W on December 2nd 1985. The average date of the first freeze is October 23 at elevations below 407 ft ASL and October 29 above 440 ft ASL.

  23. A great stretch of weather albeit dry....with the only chance of rain being late Sunday night with the passage of a cold front. Behind the front temps will fall to below normal levels for early October with even some lows in the 30's possible by the middle of next week.
