69 for the low. DP 67

Looks like people in the southern tier might see some serious storms today.

Heavy heavy rain in camp hill. These little cells are hyper efficient rain producers. I have a feeling the main issue today is going to be some bad flooding. The whole atmosphere is primed that way. Any storm damage is going to come from wet microbursts, but any wind is bad with weakend trees, now a wet upper soil. Uprooted trees are going to happen with any semi significant wind. Hopefully the bigger wind issues stay south today. I'll gladly take my chances with 5" of rain vs even a 40mph gust today

They all are going to be like that today. The AFD kept hammering how efficient the warm rain process will be today with tall skinny cape and warm clouds up to 11k ft. A little blob is going to put down a whole lot of rain. Someone is going to see 2"-5" today.

Low of 71 with a rounded-up .01” of rain from a brief early morning mini shower. Late this afternoon could get very interesting around here.

I'm hoping we can get some steady rain. These fast downpours suck due to run off which does nothing to recharge groundwater
