PECO saying power won’t be restored until 11pm tonight. Glad it’s not an NFL Sunday.

If it was an nfl Sunday with the eagles playing, the power would already be restored.

Interesting that they issued a heat advisory for today. I don’t think I’ve ever seen that here with a high in the 80s.

We got the south end of the cell that went through Chester County @8:30 last night. Transformer blew in front of my house. Lost power for 3 1/2 hours and then again for a little bit overnight.  Impressive wind. Fire companies running silly all night last night.

..Mid-Atlantic...

Farther downstream, scattered to widespread heavy rainfall will be focusing along the wavy, east-west orientated frontal boundary draped over the northern Mid-Atlantic states and offshore south of Long Island. Back building/training of slow moving storms capable of hourly rates rates greater than 2 inches/hour will track across eastern Pennsylvania and New Jersey this evening. Guidance is signaling areal averages of 3 to 6 inches with local maximums of 8+ possible along this corridor.

The latest guidance maintains focus of the highest probabilities for the intense rain rates and higher QPF over central to eastern PA, portions of central to northern NJ, and far northern Maryland. The combination of some terrain areas and the highly urbanized corridor makes this area much more vulnerable to flash flooding.
While there remains some spatial uncertainty to exactly where the greatest rainfall will occur, the setup favors locally significant flash flooding with the Moderate Risk over eastern Pennsylvania and north/central New Jersey embedded in the Slight Risk that now spans from northeast Indiana and southeast Michigan (including
Detroit) through the Mid- Atlantic Coast from NYC to central Virginia.

On the bright side, I’m saving on my PECO bill today

This is what I was seeing last night as a potential for training t storms overe my area. I saw this similar setup in the 90,s. That's why I am concerned about down trees acting as debris dams in the flooded streambeds 5 + inches of rain will cause this to be a serious problem on major road bridges. Yes the rain is needed but not in 4 to 6 hours. Really. You should all drive around and look all the fallen dead trees in the streambeds now. It's horrific

Some rain totals from the storms last night. DEOS stations at Atglen 0.72" / Chester Springs 0.48" / Devault 0.66" / Glenmoore 0.60" / Kennett Square 0.42"/ Longwood Gardens 0.18" / West Bradford 0.51" / Nottingham 0.54" / Warwick 0.42" / West Chester 0.19"/ West Grove 0.13" / KMQS Airport 0.46"/ KOQN Airport 0.10 Our run of 90+ days should end today for most folks across the area. In fact looking ahead at least I suspect we may not see another 90-degree reading for the next 10 days. This week will feature below normal temperatures through Wednesday with highs tomorrow through midweek in the mid to upper 70's. It will however be a wet week with rain chances later today through Tomorrow night and again Thursday into Friday. The driest day looks to be Wednesday.

PECO workers are striking.

The criteria uses the heat index and duration of the heat event (and the dews have been horrible the past couple days, although at least not in the 80s yesterday or today like last week).

Has the Jordan Creek ever come close to flooding route 100 by Hoffman's garage or the KOA turnoff?

Some stuff popping out to the W. Earlier than the previous 2 days at this time...
