West Chester must have just been/is being smacked right now?  
 

No one has anything to report?

I'm south of there, and so far it's been a pretty cool light show, with some huge ctc lightning, for the last hour plus. It's all scraping by just to the NW of here, hoping we can catch the tail end of it.

[mattinpa]

A tornado warning was issued for eastern Montgomery County. Just got downpours here.

 

 

[Birds~69]

Tornado warning right above lansdale...(in pink)

[Birds~69]

Super downpour here...tornado box shifting NE.

[Joshb32689]

Another tornado on the ground near KOP

[Joshb32689]

Crawling at 10 MPH

[RedSky]

So the tornadoes happened outside the watch box eh 

 

[Hurricane Agnes]

It has been non-stop lightning/thunder for the past 2 hours so finally came down to check the radar on the laptop and assumed there had been rain all that time and nope, the line hadn't even gotten here until now when I saw I had 0.25".  Now the front edge of the line has moved over my area and am getting almost 3"/hr rates.

[Hurricane Agnes]

Now almost up 4"/hr of rain - at 1.17" at post time. Temp is down to 76

Getting badly needed rain is often like pulling teeth good to see you broke through 

 

 

[Hurricane Agnes]

Am over 5.22"/hr rates. Am at 1.82" at post time.

Yes!  The line has been solid coming through.  Now closing in on 2" from this so far.

[Hurricane Agnes]

Still getting raked  and now up to 2.81" of rain from Fred. and still well over 3"/hr rate but dropping.  Temp is 75.

[Hurricane Agnes]

Still >3.5"/hr rates.  Now at 3.10" for the event at post time.

[Hurricane Agnes]

Looks like Flourtown was reporting a water rescue. I think the heaviest is now pretty much past and currently have 3.42" in the bucket with 0.61"/hr rate.  Like a month's worth of rain in an hour.  Temp 75 with dp 74.  And with that, time to go back to bed.  The lightning/thunder has pretty much ended for now.

ETA - now at 3.45" and light rain at 2:30 am.

[Hurricane Agnes]

The 3.45" was my final for the event (now at 6.78" for the month so far).  I saw where the Wissahickon Creek went out of its banks (I think ~5ft is flood stage).  I'm good through the weekend.

It's currently a very wet and mostly cloudy 73 with dp 73.

[Birds~69]

74F / DP 73F

[Hurricane Agnes]

Will have to say that however innocuous Fred was when it fell apart over Cuba and never made it to Hurricane status, it still packed a wet wallop once it regenerated itself!  Wasn't expecting that rain band line to hold together although we were certainly warm and juicy enough this far east to prime the pump...

 Currently down to 73, which may end up being my low, and cloudy with dp 73

Unless I missed it I don't think a tornado happened in KOP. Think NWS is looking at a possible tornado in Perkasie which was in the watch box...

[Birds~69]

Imagine 33" of snow falling in an hour...

73F / DP 72F

[Rtd208]

Picked up 0.52" of rain so far today.

Current temp 78/DP 74/RH 90%

[JTA66]

Looks like 2.75” here. The lawn is happy and I don’t need to fill the bird bath today.

I was under the tornado warning but nothing happened here. Don’t even recall much wind last night.

[The Iceman]

Picked up 1.6" last night, light show was tremendous though. We had some good booms from just after midnight until about 230 am. Needless to say didn't get much sleep between the tor warnings going off on my phone and flash flood warnings. Felt like the storm was on top of us for hours based on the lightning/thunder but it really only downpoured for 30 mins or so.

[KamuSnow]

Picked up another 0.24" here yesterday/last night, bringing the monthly total to 0.96". Racking up the rainfall here, a quarter inch at a time! Nice breeze this morning!

Seems like you're in a relative screw zone with rainfall in SE PA. I'm over 5" on the month now with many places near me also above 4". Delaware county has been in a rain hole this month.

[Kevin Reilly]

Here in Media Delaware County picked up 0.44" overnight.  we have 1.94" for the month of August so far.

 

As of 10:50 pm while I was passing by Chester Creek was pretty high to about banks at Middletown Twp.  Ridley Creek was at bank full at Media along Knowlton Road and Crum Creek was below bank full at Beatty Road in Springfield.  All creeks were moving pretty swiftly and all brown.

The watch zone I saw didn't include Montco and Bucks unless it was expanded at game time. 

3" of H2O

Anyone else in South Philly? I feel like the rest of the region is well above average the last 6 weeks while we are consistently getting screwed over and over again by these storms. Like North Philly is above average for the month and we are approaching abnormally dry conditions. My concern is we will exit this wet pattern but with none of the buffer our neighbors have. Anyone know where I could get official numbers on past 24 hrs of rain in my area e.g. a resource with measurements from spotters nearby? Is there anything similar that looks at a longer timespan like weeks? Thanks

Mt. Holly reports what is submitted via CoCoRaHS here - https://www.wrh.noaa.gov/total_forecast/getprod.php?new&prod=XXXLCOPHI&wfo=phi

and any Local Storm Reports here (if/when people submit them) - https://www.wrh.noaa.gov/total_forecast/getprod.php?new&prod=XXXLSRPHI&wfo=phi

and Public Information Statements here (if/when people are submitting them) - https://www.wrh.noaa.gov/total_forecast/getprod.php?new&prod=XXXPNSPHI&wfo=phi

At the moment, the CoCoRaHS reports seem to be the most complete, although there are only a handful of Philly reports.

I recall last week the Phillies had rain delays on 2 consecutive evenings - 8/10 & 8/11 (one of my BIL's was at the first game).  Sometimes you guys get the northern fringe of the storms that come through northern MD and Wilmington, DE.  Whenever I have been running either of my doppler programs (GR2Analyst or GRLevel3), I don't recall seeing mpings or other spotter reports from down there though outside of the airport (KPHL), which is the official reading for down there too.

I attached a radar image (with 3 overlapping severe thunderstorm warnings) over S. Philly on 8/10 just after 8:30 pm & on the look on 8/11, about 7:50 pm.
