And there goes the power! A couple lights are glowing very dimly. What's up with that?

[weatherwiz]

WOW! 

I ended up missing the best stuff b/c on some Wednesday’s I’ll do trivia in WeHa with a friend and I didn’t cancel the plans tonight. Sitting at WOB in WeHa Center, inbeteeen one of the rounds I went outside...this was several minutes after the SVR...I’m assuming we had decent winds b/c I could see the trees moving outside and they are not tall at all...like those 8 footers you’ll see planted on sidewalks. 

 

First off, that was some of the most intense rain I’ve ever seen...it was legit buckets. The lightning/thunder was incredible. Took some video and posted on YouTube.

One week with each side of Fam. We Cape this time.

Not to take away from the current weather, but radarman got me curious and looking. Looked up the ISP top hours and although 2014 didn't top me, they had a couple of monster minutes 7/18/07. Someone would have to pull up the radar from that. 0.26" and 0.21" in consecutive minutes. Nuts.

Haha.....seriously though....it seemed like God just turned on the hose on full....it was so much water....the constant lightning and thunder was so great

[ineedsnow]

1.54 so far.  Really good drink but not the flooding others had

[TalcottWx]

Middlesex needs a FFW

[CoastalWx]

Pretty much some CG and +RA it seems.

Fishy looking rotation nw of BOS

areas just west of Framingham nearing 1.5" so far

That's what we have had up here... though nothing remotely close to the +RN rates that Brian had.

It was just your garden variety stuff, still steady rain and lots of on-going rumbling & flashes of lightning just to the NW of here. 

 

[TalcottWx]

Cells west of Providence will be a close shave with BOS proper, but I think we get hit. 

Then second round shortly afterward.

Hail! Peas and fat drops

[TalcottWx]

The 12z ARW came closest to predicting this. I have limited access to models, just trop tidbits.

idk what to tell you. Every few years I pull off a 0.10-0.12"/min. Either last year or the year before I recall a 0.14", but I'd have to go digging. I've never had anything this high...nevermind 2 straight minutes of it. You know how random this stuff is. I've had storms drop 2-3x this total with a 1-min max of like 0.10", but it ends up raining for 45 mins at 4"/hr.

 

Looked up the record hourly rainfalls for some sites and found one from 2015 for CON. They pulled a 0.19" in 1 min...0.47" in 3mins (more than me) and 0.73" in 5mins.

 

Do you know how they calculate the 21"+/hr rain rate you mentioned?  .17" in 1 minute projects to 10.2"/hr which seems more reasonable, while still extreme.  Granted within the minute it could fluctuate but not sure if they take the nearest 2 tips or something and calculated the rain rate that way.  

Your somewhat protected spot (relatively speaking) may be better equipped to measure heavier rates than a windy wide open airfield, and may compensate for climo differences in TX with respect to moisture.  The .63 in 1 minute I measured was almost certainly erroneous for some unknown reason but the minutes before and after were roughly on par and seem plausible.  I regret casting doubt on it in retrospect!  

[HIPPYVALLEY]

Farmer friend in Greenfield messaged me and said only .25" there so far today?   How is that even possible? 

[TalcottWx]

Ginx to ORH there is actually some decent straight line wind it seems just off the deck
