UK heatwave = 3 days above 75F

Canaan Valley WV got down to 31!

Some PWSs near @psuhoffmans house in the 46-48F range. I assume @psuhoffman actually has light frost this morning.

Just saw a tweet saying the Mullica Hill, NJ tornado will be AT LEAST EF3.

Now imagine if all this precipitation was snow.

Maybe one good thing about the changing climate is that maybe we can get our cat 5 up the Bay in January!?!

Crazy how areas of north NJ that saw so much rain from Henri also were bullseyed from Ida. Got to be some places with over 12” of rain in 2 weeks?

Down to 67 now, which is pathetically the coolest temp since the morning of August 8 I believe.

Some of the damage vids from the nj tornado looks like an ef2 minimum.

I’d wager ef3 for some of the pics I’ve seen

Going to end up with a bit under 3" total rainfall, most fell overnight.  Today was fairly meh IMBY, but clearly a pretty memorable tropical remnant event area-wide.

First thunder with any of the daytime cells

Same

Little patch of blue sky overhead with a good view of the strong storm approaching Baltimore just to my east. 

I'm sure someone in FredCo will say conditions were "unexpected" or some nonsense like that.  Always blame the forecasters.  

This is from one of the Orioles announcers

Cell north of Towson heading for @mappy now warned

@Ian says debris signature on radar from the Annapolis twister

Was just about to post some spinny velocity scans on the cell near King George VA. But I see it’s already warned.

@WxUSAF Don't worry but work quickly: I got water, 0.25~0.50", across half my finished basement last week from a thunderstorm dumping 2.5-3" in ~2hrs via a basement window well.  I freaked out and worked through the night to get the water up, started a dehumidifier, and then grabbed 2 smaller ones on sale.  Been running them all and RH is 35%; the water didn't even reach the drywall, it was absorbed by the 2x4 frames.  As long as it isn't reoccurring or consistently moist down there then you should be fine (3x coats of moisture barrier on the walls here in soggy wstrn PA).

Also bought an automatic pump from Harbor Freight should anything close to that try to happen again.

Thanks for the feedback. We didn’t even have anywhere near that much. Just a damp spot in the corner and then a small “puddle” next to that less than 0.1” deep. 
 

I always run a dehumidifier back there and I have a fan blowing on that area as well.

HoCo dismissing 3 hrs early

Bummer.  Glad it isn't any worse.  Now you just have to worry about getting slabbed later.  We all do.

Yeah, then my slab will flood. 

My inkling is that very rare water into the basement isn’t worth a major intervention. 

Got a little water in the basement this morning after that deluge. That’s happened a handful of times since we moved in after the most intense rain. I don’t think I need to be too concerned? Just will clean it up and dry it out as best as possible.
