With the frontal passage last night and a couple more over the next few days we should see a great stretch of dry and comfortable weather. The only real chance of rain over the next week looks to be late in the day on Sunday.
Chester County records for today: High 104 degrees at Phoenixville (1925) and 97 degrees at Coatesville in 1899 / Low 37 degrees at Phoenixville (1945) / Rain 4.19" KMQS Coatesville Airport (2013)
Should be a nice day albeit a bit warm. The good news is we only have about 100 days of consistently warm weather left and they are ticking down quickly.
Thanks for all the valuable information. I didn't know about the "old school" methods of using the DP's as an indicator. I agree with you, this is more or less a "transitional" phase in the pattern from what I see and my gut is saying. Nevertheless, the Monsoon officially starts on June 15th and ends Oct 1st. Last year was a big bust so I'm sure the valley and the mountains are ready for Monsoon action. Fires have erupted up in FLG and ppl are getting worried bc of all the brush that dried out from a great winter and spring. I'm very interested to see how this summer evolves down here in the SW.
