Looks like the high 500mb heights and warm 850mb temperatures in Russia and the Bering Sea are bumping the upper level features to be cold in North America.

some crazy ensembles with some ensembles with heavy snow at Chicago, Indianapolis, almost St. Louis

This is a rapidly changing jet stream disturbance that's going to get the new low pressure going in Ontario, going backwards, as the rest of the trough goes forwards.

I believe the 1864 storm is covered in "Thunder in the Heartland," by Thomas Schmidlin, weather historian. When I read that book, I didn't make any specific notes, as it was almost impossible to find a weather observation that I could have included on my web site. If you look at the Daily Weather Map archive from the government (back then it was the US Weather Bureau) you can only see back to 1871 (amazingly). -
Sea-Tac had 55mph wind gusts from the ESE, and I have heard 500000 are without power around Seattle with similar circumstances with some easterly downslope winds. I've never seen a low pressure get down to 945mb so quickly unless it was a hurricane, I think.
-
blizzard warnings, hurricane force wind warning offshore, high wind warnings
-
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

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.
