Some debate ongoing on NWS Chat on whether that vid is legit

Cape Cod vacation camping trip FTL. At best we're talking strong onshore flow, chaotic waves, and highs in the 60s. At worst, misery mist. Ugh, we scramble for alternatives.

North Texas was nutso this spring, granted with no very strong tornadoes. Typical Nino conditions really.

It has been very frequent I will say that

Agree I haven't seen much that has me concerned here on the UMass radar

This

Strengthening now... A single clap of thunder too. Awesome looking system, someone might well get hail we were oh so close

Visually very impressive TCU but ever since it was over the Berks it hasn't looked great on radar.

BOS did not record precip yesterday and may go down as missing

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!

Over 2.5" now, coming off about the same on Saturday.

Thanks. As an aside, I have been receiving one minute data from 5 Davis gauges scattered across DFW airport for about a year now. A quick check revealed only 17 minutes (combined) where a gauge reported over .1" in a minute. All but 3 were .12 or less. On 9/22/18, 3rd wettest day at DFW airport all time (>8"), at the same gauge we had .14 and .19" in a three minute span. And in between... .63". Otherwise the gauge data looks perfectly normal and have never had any other outliers like that. Hard to explain this sort of thing in sensor data. Inclination is to toss, but I guess you never know.

Anyway in the midst of the gauge discussion, we've been having some seriously heavy duty CTG and pounding rain here too.

Could just be a time thing... A few minutes of good tips recorded with the same time stamp? That is known to happen with various data loggers. I'm not sure you could record 20"/hr rates if you had the hose hooked up based on the size of the intake funnel. And even if so splashover would be off the charts. Not sure rain rates like that exist.

Probably some erroneous tips being recorded.

63MPH atop Mt Tom

This is the most notable frame that we observed so far, about 20 minutes ago

We're seeing a little bit aloft, but not on the lower scans at present

Yeah definitely took on a more ominous look in Southampton, approaching Easthampton. Brief velocity spike, but magnitudes have come back down.

Yep I was there the 23rd making powder turns on Goniff.... And that was before the 30" that fell a few days later. Best start to the season ever, an all timer in the books in met fall. The first day of met winter wasn't shabby either

There was a substantial latitudinal gradient on the hot weekend for sure. I was in Keene barely at 90 when BDL hit 100. Even my torchy station at UMass only briefly touched 95 which has not been terribly uncommon in its lifetime.

Fwiw the Amherst coop had July as the 7th hottest on record going back to 1893. 1.7 degrees off the record from 1955.

Hail to 3/4" reported in Amherst/Btown per skywarn

SVR issued for 60mph gusts and penny sized hail. Seems very legit with definite storm scale rotation and a strong dual pol sig, especially over N Hadley

Pretty good structure on this puppy, just nw of the UMass radar
