Today we may struggle to get out of the upper 60's across some of the higher terrain in Chester County. Lows tonight could see the 40's especially in the lower spots and valleys. This would be the first reading in the 40's since our low of 49.5 on June 20th.
Our record high for today is 93 degrees from 1927. The record low is 35 degrees from 1895. The daily rainfall mark is the 1.85" that fell back in 1904.
This morning's low of 48.6 was our coldest reading since the 47.8 back on May 11th. A near normal day today across the County before a warming trend kicks in starting over the weekend and lasting through most of next week. We should see temps rise to well above normal with highs in the low to mid 80's for most of next week. That is a good 8 to 10 degrees above normal. There is a slight chance of showers on Monday but otherwise dry through the period.
The record high for today is 91 degrees set in 1991. Our record low is 36 degrees in 1913. The record rain was the 7.85" at Coatesville from 1999. That rain was the result of Hurricane Floyd and is the greatest 1 day rain total since "official" record keeping began back in 1888 for Chester County PA. I was actually in Thorndale PA for that storm and we received 8.38" of rain.
Our warming trend gets well under way today as we rise to the above normal upper 70's to near 80 across much of the County. Above normal temps should continue through Thursday before much cooler air again arrives on Friday with highs on Friday again failing to escape the 60's in many locations.
Our record high today is 93 degrees set back in 1915. The record low is 36 degrees set back in 1959. The daily rainfall record is the 3.01" that fell in 1995.
The next few days will continue to average above average temperature wise before a sharp cold front and switch to autumnal chilly weather arrives by Thursday. We should see high temps remaining in the low to mid-60's by Friday. Those kind of temperatures are typical for mid-October than late September.
The record Chester County high for today is 93 degrees set way back in 1898. Our record low reading was the 35 degrees set in 1990. The daily rainfall record is 3.90" from 1945.
Today looks to be the warmest day of the week across Chester County with temps warming into the low 80's. There is a chance of some showers especially across NW Chesco and Berks Counties. A little cooler tomorrow and then near 80 again on Wednesday. Looking at some longer range models that may be the last day we top 80 degrees this year in the County. Much chillier air more typical of mid-October arrives by Thursday. Temperatures on Friday will struggle to get into the low 60's with low to mid 40's for lows by Saturday morning.
The record high for today is 92 degrees set in 1983. The record low is 36 degrees set in 1943. The daily rainfall record is the 3.27" that fell way back in 1894.
