Central PA Summer 2026 Discussion/Obs Thread

[Mount Joy Snowman]

Low of 69.  Could be some potent storms around this afternoon.  I expect my mowing prospects will be disrupted.

[pawatch]

66 degrees

I guess we will see what the rain gods deliver.

[Superstorm]

Great August temps!

Headed to Lititz tonight for a concert hope any storms are before say 6 pm. But that seems doubtful ha 

[ChescoWx]

We are under a flood watch thru 2am for between 1 to 2 inches of rain and maybe more for some spots that get under a thunderstorm. We will get cooler tomorrow and that will last through the next week with temperatures mainly in the upper 70's to near 80 degrees for high temperatures. We should see nighttime lows back into the 50's by early next week.

Steady rain the last 15 minutes.

Heavy, heavy rain. Blustery too 

[Mount Joy Snowman]

It’s funny, I was just studying various types of radar and thought to myself, “damn that looks like a rotating cell coming right us”. Sure enough, just got tornado warned. Phones went nuts ha. Have the fam in the basement.
