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.
