* Assuming no rain today which (looks out the window) appears to be a safe assumption. May tie for 4th tomorrow if it doesn't rain before midnight.

Relatively unlike to crack the top three.

on the evening of Saturday, September 7, around 9 pm. Maybe that rain didn't reach Boston?

Remember for any weather to be reported as official, it has to be recorded at Logan Airport.

If it didnt rain at logan, it didn't happen.

But I agree, that weekend it DOWNPOURED for at least an hour or so around that time. And mind you, I am ~1 mile away from Logan so not sure why this wasn't reported.

There are multiple types of stations reporting, not just the airport ones. There are GCN and COOP stations that aren't at Logan that report to various networks. The trick is that, even with nearly two centuries of observations, there are not any comprehensive things that aggregate all this. Some states have longstanding records from their own state met offices - which MA doesn't really have. Scraping Google Earth Engine and processing in R is possible if you want modeled data for many areas of the state, but geotiffs are a beyotch to deal with - I'm likely going to hire an intern to put it together so I can have not just Tmax but also humidity and heat index data to work with. It's a tedious mess and there is no one place just putting it together. Forget NOAA - that's a fucking joke with PDF files for each month in nonstandard formats - and you can only pull down a handful at a time.

Then TV ppl are wrong?

This is what Harvey Leonard has said.. for a record to be official in Boston (city) it has to happen at Logan Airport because thats where the weather station is for the city.

There are other places where records are kept and measurements are made.

If you look at the precipitation projections in the 2023 ResiliantMass Plan, we can expect longer stretches of dryness in the warmer months to continue and become more common.

The more recent projection models are showing drier summer and fall weather overall - mostly due to hotter temps meaning the air hogs the water - and wetter winters.

See chapter 3: https://www.mass.gov/info-details/2023-resilientma...

Weather does not equal climate.

We had a very wet summer last summer. We ended this summer on a dry note. I'd put cash on the rainfall Jun-Aug 2025 being within 10% of average- 10.39 inches.

To read more carefully, and react only after reading.

If you look at the precipitation projections in the 2023 ResiliantMass Plan, we can expect longer stretches of dryness in the warmer months to continue and become more common.

We can expect more WEATHER like this because THE CLIMATE is changing.

I think that was pretty clear in what I posted, but you had to pretend that I said something that I did not actually say so you could spew your little talking point and "lecture" an actual scientist.

Don't quit yer day job, JDjr.
