7 inches in 90 minutes is some extreme rain Mike.

So is this from climate change?

It's not even close to a record! The record for 90 minutes is 14.60" set in May 1943 in Central WV.

What's interesting about all the record U.S. rainfall events below is that 1 took place in 1`996(25 years ago) and  the 23 other ones happened prior to 1983 and BEFORE climate change from humans!

For fun, I dug up the all time records for PA for each month for temps, rain and snow.

https://climate.met.psu.edu/data/state/staterecords.php

In the last 20 years, there was 1 record heavy rainfall month(Oct. 2005) and 1 record snowfall month(Feb 2010) but other than that, especially with extreme temperatures ALL the records were BEFORE climate change.

This is not odd. Temperatures and some types of weather have become LESS extreme from climate change not the other way around.


It's not just PA.............that's the way that it is with most US states:

As you can see here too, from official NWS records going back 100+ years in most cases........the vast majority of record extremes for most states were recorded BEFORE climate change.

However, when we have an extreme that happens today...........the story covering it very often claims that climate change was a factor or even caused it. Nobody has weather records going back 100 years............so they all believe it.....and that's why they can say it............because nobody fact checks or holds em accountable.


The slightly warmer atmosphere can hold slightly more moisture so rainfall has increased slightly but many of the other extremes have DECREASED, especially violent tornadoes(not recorded here).

Recent Tornadoes are Due to Unusually Cold Weather

https://www.drroyspencer.com/wp-content/uploads/tornadoes-1954-2018.jpgAs has been pointed out elsewhere, a trend line fit to the number of strong to violent U.S. tornadoes has gone down from 60 in 1954 to 30 in 2018. In other words, the number of most damaging tornadoes has, on average, been cut in half since U.S. statistics started to be compiled.


metmike: This is totally expected based on the authentic science/laws of physics.

When you decrease the meridional temperature gradient(from less cold air at the highest latitudes) you have less energy potential to feed weather systems. You also weaken cold fronts and jet streams that contribute the most towards the high end tornado outbreaks(200+ mph winds for instance).

The incidence of weaker tornadoes have gone up a bit, however,  mainly because, in the 1990's, we installed tornado detecting NEXRAD DOPPLER radars across the country that can see and measure the wind, including in many weak tornadoes in rural settings that exist briefly, did not do much damage and went unreported previously with the old radar systems that did not detect them.
