Collegeville had a severe thunderstorm warning and flood warning - by far the main thing seen was very heavy rain.

A big 0.25. This is why I laughed at last night's forecast of 1-2 inches here

So based on what occurred. I think the 5% tor risk was realized and the 18z IAD RAOB told the story. Once again though, the bay and the Delmarva played a big role I think. There were several storms early on over the Delmarva, and maybe they laid down subtle boundaries and interacted w/ any bay breeze boundaries, so when the Colesville weak supercell arrived on the scene (you can trace it back to the DOV tor), it intensified quickly. Actually looking at the radar loop, there were two waves of storms over the Delmarva. First was around noon and then another close to 4pm. Looking at where they fired, it appears there was some kind of boundary N-S over cntrl DE. Also, there were several cells ahead of the main line that merged in, and cell mergers can lead to tornadogenesis. Radar loop attached.

He’s a few houses away from you. Better check your setup there on the tractor . We will also verify in the morning with other local sites and mesonet

1.68" storm total here. Stars are beginning to come out now and will be a cool late summer night.

The bust calls before the event starts are always the best.... - missed the big totals here but well over an inch so far with a bit to come

Just had that showers / boring steady light rain look away from Scoast .

3-4” for you by the time it’s done. Probably at 3” already.

Yeah that is about where much of the guidance had it, plus it was probably convectively enhanced some.

December 1986 looks like a pretty good match, too.

Little line over my area. Raining fairly hard

1.00” of rain at WXW1. Meanwhile it’s 58° and clearing here at WXW2. High of 68.6°. Fall is on the way here.

Legit tornado in Atlantic beach. Those videos and damage pics make me think strong F1 or perhaps F2.

Man this thing is decaying. Love a good Stein.

Feels amazing out there. Temperature 59 with a gusty NNE wind. Feels like mid September! Opening the windows tonight! Rainfall for the day: 2.14". August to date: 7.61" Since 7/1: 16.60" Since 6/1: 22.11"

.93 Chance of showers this afternoon.

First mid-lat bomb with snow on the GFS

3.00" so far. Just relentless torrential rain since it all started at 7pm so averaging around 1.5"/hr for the past 2 hours now. Had a rainfall rate of over 4"/hr at one point.

I’m pretty sure the actual low pressure probably like 1010 mb passed right overhead here in central Delaware County looking at the cloud and wind vectors visually.
