Chinook

This narrow band is right at the front

The NWS radars work well for something like 60+ miles with the low altitude snow, including lake effect snow. Then, I think they overshoot the clouds and snowflakes. You can see it all over the region. It's pretty commonly a problem with detecting lake effect snow. Also, areas in the vicinity of Findlay have the least accurate tornado warnings, given the fact that tornado warnings mainly come from radar. That's bad, but worse radar holes for severe weather exist in the plains such as east of Dallas.

It looks like the Detroit general area is getting into more accumulating snow now

I think my area already has 1/2" of snow tonight since 6:00 or 7:00 eastern.

Extremely unusual values of 50 to 54 degrees below yesterday, in Missouri

Toledo had a high 61 (low 33 yesterday morning) with various levels of rain, and heavy fog. No lightning/thunder later in the evening. Then with the temperature dropping, Toledo has maxed out at 50 knot (58mph) peak winds. Wind chill was briefly 0 when the temp was 18 and the wind was 30mph. 0.52", and also measured values up to 0.60" and 0.70" on CoCoRAHS. A few days back, the WPC/NWS estimation was 1.6" but a lot of that shifted to Detroit. (Oakland County got that much)

63 degrees in Monroe MI

storm reports and warning boxes today

tornado debris signature was near Clifton IL at 3:48 Central

5 tornado warnings, possible tornado near Jeffersonville/Fairfield Illinois

these non-confirmed tornado warnings are near some family members in Indiana

this was a confirmed tornado in Illinois

a few radars from MN/IA

when the ensemble says 18", I'll say 36"

sleet/snow at Toronto

temperature profile near Detroit- huge inversion

ice storm in Michigan

I'm glad to be 110 degrees warmer than this

Happy Festivus! I got a lot of problems with you people!

Mt. Washburn view from Yellowstone NP. This particular webcam is mostly in the clouds these days, even with the general lack of snow. The other web cams show some non-snowy ground at the entrances to the park North Entrance- Electric peak

With some temperatures in the 50's coming up, this 11 degrees below normal is going to get wiped down to being just a bit below normal, maybe

Some more very high winds of 60-110 mph in Boulder

The sun is now burning the other side of the Earth! So terrible for them.

One of my ideas is that La Nina slows down the subtropical jet and enhances the polar jet along the US-Canada border (going into winter months) You can see on this chart the 30-day 250mb jet stream has been much less westerly than normal from Hawaii to San Francisco, which makes lots of sense with this idea. I also think the La Nina leads to greater wind events for Colorado. (Like today) There is definitely an upper level ridge in the averages, over the Pac NW, leading to lower precipitation out West. And a large Greenland block-Labrador Sea block.
