Central PA Spring 2026 Discussion/Obs Thread

Today will be out last day with temperatures in the 80’s with highs in some valley spots getting within a couple degrees of 90. We fall back into the 70’s tomorrow and Saturday before we fall back below normal by Sunday through next Tuesday. Some shower chances later tomorrow and a better chance on Saturday night. We could have some freeze or frost concerns by Monday night into Tuesday morning.

As per the World Meteorological Organization (WMO) Current climate normals are calculated using the past 3 complete decades and recalculated every 10 years. So, I went back and calculated what was normal for the last 10 climate normal periods specifically for Chester County PA. The below show what the climate normals were for the 10 years following each calculation with the earliest being 1901-1930 normals and the latest being our current climate normal period of 1991-2020. Averages in red are the warmest and blue the coolest across those periods. Of note our warmest climate normal period was 1931-1960 and our coolest period was 1961-1990.

Couldn't crack 90 as we topped out at 89.1 today. My Monday forecast keeps getting colder as the high is now down to 44.

I'm still of the persuasion that this summer is going to be a rollercoaster ride of AN and BN temps every week or two.

I fear it's going to be like last August but with rain. The whole time.

I’ve been enjoying the early warm up, but party is over on Sunday. 
I’m not looking forward to freezing while coaching my daughter’s softball team on Monday evening.

My wife refused to turn on the AC. So since he’s in the Virgin Islands I broke into @Itstrainingtime’s place and cranked his AC down to 58.

Was just coming to say the same thing. I jumped up and looked out was crazy.

Not looking forward to those temps, I thought with those upcoming temps that would be in your wheelhouse, and maybe you'd post a snow map

The Devault DEOS station recorded a high of 90.7 yesterday this is the first 90 degree reading at any County station so far this year. None of the other stations reached 90 but upper 80's were common across the valley locations. Today should be 10 to 12 degrees cooler with highs in the mid to upper 70's. This is still 10+ degrees above normal levels. We chill well below normal by Sunday with highs remaining in the low to mid 50's with shower chances increasing. A freeze remains a possibility by Tuesday morning.
