Peak gusts up to 75-80 mph are recorded. 1883: The 4th deadliest tornado in Minnesota history hits Rochester. The tornado kills 31 residents and injures 100 more.

The oak became a symbol of American independence and is commemorated on the Connecticut State Quarter. 1883 - An estimated F5 tornado caused extensive damage to Rochester Minnesota on this day.

Many of the 200 plus injuries were severe, and other deaths probably occurred but not listed as part of the 37 total mentioned.

Getting a few pretty intense showers here atm..nothing too heavy but it really has that mid April look outside with the sky and intermittent rains along the coast. Def gotta feel for those who’ve planned cape vacations this weekend too. Hopefully many sweatshirts and buckets of popcorn are on hand!

.75" for yesterday

I drove home from my son’s swim around 8pm from patchogue back to west babylon. The rain was so heavy people were pulling over. Intense stuff then my mother in law who was in Atlantic beach when the tornado hit land texted us she saw all the activity because they were a half mile from it

Solid soaking for everyone. Most guidance did well showing where the max area of rainfall would end up from NYC on east. Was expecting 1-2" here and ended up with 2.14". Lesser amounts just NW of here up into Sussex County with generally 1 to 1.5" up that way. Either way everyone has had enough rain lately! Meteorological Summer which has 10 days left to go has been wet. In some places VERY WET.

Low of 46 here at WXW2. Low of 37 at SLK. We cleared out last night and the temp fell like a rock.

some events they have to make in advance for vendors etc...but sucks when you cancel then it ends up ok.

Excellent shots!

Thanks for the context. It makes sense now!

I feel like September is going to be quite the interesting month. There is still potential for us to get another surge of upper 80's and 90's for many but some signals too we could start seeing some stronger troughs sliding across Canada and northern tier of the country. That should yield some interesting weather chances

Yeah. Looks like a decent day.

Yeah and I saw so many cancellations 3 and 4 days out

So much for the big torch to end the month. No idea what they were looking at.

Nice little lake in Riverside Park this morning. Dogs were swimming in it.

Amazing looking storm. Insane rain once it hit, too. Here’s a couple pics I took.

Kick this shit out of here so we can beach.

looks dry western sections for sure tomorrow. Cloudy and cool but I'll take it.

I wasn't home but it looks like 1.8 around my hill. Of course, I got a UPS delivery a few hours before the rain and it's still sitting there because the neighbor forgot to grab it

Didn't realize how blessed I was yesterday

Low of 58 to go along with 1.28" of rainfall. I expect the NWS to confirm a tornado touchdown near the Wrightsville/Columbia area today. Even over my way the low clouds had some serious rotation to them. Impressive event.

We nearly had a repeat of the August 2025 flash flood last night. It hit Ringgold and Catoosa county instead. 6" of rain in less than 3 hours.

maybe we net some small hailers Sunday
