Chinook

this low was 1000mb at 06z

Typhoon Man-Yi: JTWC said 130 kts before landfall and 90 kts after landfall, with news reports saying 121mph(105 kts) at landfall. Here is the image at landfall.

Some GEFS ensemble members and the ECMWF have a low pressure near Toledo or Detroit with snow to the south. I expect that models will take a few days to come to agreement on this dynamic system

maybe it warmed up a bit at Boulder for these guys

I'm not sure what will happen with the storm at about 120 hours from now. New models have a really low pressure near Detroit, with snow in Ohio. The models have been changing rapidly. Guess what? I made a new loop! The Great Lakes Storm of 1913 (20th Century Reanalysis) https://great-lakes-salsite.web.app/Great_Storm_of_1913_loop.html

this is up to a category 5 (starts at 137 knots)

Typhoon Man Yi is expected to peak at 115 kt (low-end category 4) soon, also it is close to the Philippines. It is going to be 115kt down to 90kt just offshore from the Philippines and make landfall.

this is neat

College of Dupage now has the ECMWF to 360 hours

new loops for the huge storm, as I now will call it, the Denver double snowstorm https://great-lakes-salsite.web.app/Nov_5_2024_surface_loop.html https://great-lakes-salsite.web.app/Nov_5_2024_500mb_loop.html https://great-lakes-salsite.web.app/Nov_5_2024_radar_loop.html

hey, I just found this interesting video about a terrible tornado in New England edit SPC's reanalysis view of helicity for this isolated tornado

I kind of wonder if Toledo just was simply colder, for some reason I can't explain, that is, not due to consistently rainy conditions (obviously.) Fort Wayne had +3.6F.

This is epic. The great storm of December 1st-5th 1913 had over 40" in Denver and this says 38" east of Denver. By the way I did a quick check of the biggest snowstorm in Colorado Springs (Airport) in modern times and it was something like 19.5 in October 1997. (1997-1998 El Nino)

Detroit was +3.5F for October, Toledo was +1.6. Detroit had a warmer average temperature, Detroit had 56.5, Toledo had 56.2.

Interesting coincidence at this time of year, early November. It's not exactly an analog, well, not 100% match by any means. There was a deep trough in AZ/NM that created a heavy snow storm for the Plains in 1991. It was coincident to the Perfect Storm. It's partially because the Perfect Storm blocked up the ridge in the east. There was 10"-20" by Pueblo and Trinidad. The snow continued up the Plains with, I believe, 15-30" by Duluth, Minnesota. Maybe Mayjawintastawm actually was in Massachusetts for the Perfect Storm's waves. Maybe you saw George Clooney sail out on the Andrea Gail.

so I guess this is happening

Here is a snapshot of hour-to-hour record breakers

new confirmed tornado north of that one where I showed the funnel cloud icon

small squall-line tornado at Crane MO

This report icon is actually a funnel cloud, by Branson Missouri

now this is showing a large debris, with easy to see 70-80mph storm relative winds on the west side

this tornado has tracked maybe 10 miles in eastern Oklahoma

with all apologies to Phil Collins of Genesis... here's the next DenverBoulder forecast dicussion. Note NWS-WPC has 1"-3" total QPF in the next week from Denver to the southeastern portion of Colorado
