If the Eastern US is going to be cold in a strong/super el nino, I feel like the record warmth will have to be centered around the PNW or southwestern Canada. (2009-10's record warmth was centered around southwestern Canada, which had an effect on the 2010 Winter Olympics.) The fact that there is a warm signal in southwest Canada is promising.

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.

HRRR has hardly anything until very late tonight, but can't rule out an isolated downpour before then. Really hoping for some good rain tonight and tomorrow -- we've had bad luck with the heavy rain missing here the last couple days.

Ugh, that June 2012 derecho event was awful! It was over 100 degrees that day and still at or near 100 into the evening right before the blast hit. Knocked our power out for 2-3 days solid which was miserable because the following days were still in the upper 90s. During Sandy we didn't have a power outage (or perhaps very briefly, can't recall exactly?) even with the more consistent winds. There was better prep during Sandy for sure as I recall...but also, the derecho ironically cleared out a fair bit of older trees/growth so that by October there wasn't as much to fall or get uprooted. (ETA: Interesting tidbit about the derecho event. Didn't get a lot of rain from that where I was, it was primarily a literal blast of wind in a concentrated amount of time. And there was a TON of lightning.)

Really interesting storm movement yesterday too!

Final standings including the 0.90" of total rain tiebreaker (DCA 0.02", BWI 0.82", IAD 0.04", SBY 0.00", RIC 0.02").

As others have alluded to, the lower dew points yesterday probably led to so much downdraft cape that the damaging winds superseded the heavy rainfall threat. With higher dews today, the HRRR in particular suggests a greater heavy rain threat, although it delays initiation later than several other cams.

Probably ok through 5pm...after that who knows

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

Just now getting back on the grid, power is still out here. Absurd how fast and hard the wind came in yesterday, widespread damage between Taneytown and Emmittsburg. Can confirm it was worthy of that PDS designation. doing a damage tour with the wife right now, one of our most impressive storms in years with regards to ground truth.

Suprised all is quite here after last nights severe thunderstorms. 35,000 people in Dutchess had no power last night. We have been on generator power since 3 am. Trees down everywhere, hail, lightnight and 70 to 80 MPH winds ripped everything up that wasnt tied down. CoCoRaHS measured 1.60 inches of rain near me but i would say it was twice that amount. I havent seen a storm like this in many years.

Got clocked pretty good yesterday, storms came in right in time to ruin fireworks but picked up a quick .55 for my garden

I’d be very worried , but I’d pretend that I wasn’t on here

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

12k NAM gone wild over Mt Tolland

RRFS and HRRR both say ease way back on widespread massive totals , flood watches etc. . Not saying either are correct , but the convection to the south concerns are real .

How far would you toss the extended HRRR if this were winter?

..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.

Further SE but good luck trying to pinpoint the JP

Now post the HRRR

Both NAMS destroy CT

Think we make it until 6-7pm without rain today? I don't really care too much about fireworks, but our town is having a huge festival all day with food trucks, bands, and a watch party for the Brazil vs Norway game at 4pm. Would be nice to get the fireworks in too...

Hoping today we get under a nice cell. We have missed out all week.

I keep thinking my PWS runs warm with temps. But you hitting 106 makes my 106 seem legit. It’s 3 days in a row where I’ve topped 104. That’s just nuts
