2.68" of rain measured on campus at Penn State since yesterday morning. We're now up to 18.74" since the beginning of astronomical summer on June 21 -- wettest on record in that time frame, even topping the 18.25" in 2018 (which was part of our wettest yr on record overall) #pawx

2.53" of rain in State College yesterday -- wettest day here since November of 2022. We're now guaranteed a top-7 wettest meteorological summer on record, even if no more rain falls this month. #pawx

On June 22, State College was running an almost 3" rainfall deficit year-to-date. But, after almost 6" of rain in the last couple of weeks (including a daily record 2.11" yesterday, the deficit is gone and we have a small surplus year-to-date. #pawx

High temp yesterday in State College was 93º again, which means our string of no 95º+ days -- now approaching 14 years, lives on. It's the longest such streak on record by more than 2 years. #pawx

State College high was just 93 yesterday, but the min temp of 77 ties the highest min temp on record at the site (it’s occurred 10 times, most recently in 2011) #pawx

Tmin of 76º in State College was actually not a daily record (77º in 1901), but still represents upper-echelon nighttime warmth. It's only the 16th occurrence of a min temp 76º+ since 1882, and is just 1º shy of tying the highest Tmin on record (which has occurred 9 times) #pawx

Pretty wild that State College has two record lowest max temps in the last 10 days (49º back on May 14, 51º yesterday), and sandwiched in between was a near record high (90º on May 18). #pawx

Looks like Philadelphia has hit at least 98º today. That's going to be a new record for the month of May pending official data #pawx

Impressive chill this morning even at stations that didn't set records. 34º in Philadelphia and 26º in State College both mark the coldest morning this late in the season since 1989. #pawx
