Chinook

16 degrees with mixed sleet/ snow. Looks pretty heavy

neat!

my thermometer has never been below zero until today. I got it in April

Finally my county (and all Ohio) has been upgraded to Winter Storm Warning, after some uncertainty( Lucas, Wood) and also Monroe County Michigan

ping! snow and sleet storm report apparently says 0.5" of sleet. Moderate snow (1/2 mile visibility) near Oklahoma City. There's got to be some decent sleet/snow by the Red River.

hour by hour it had -45, but if -48 happened on a non-hourly observation, I'd believe it

This has got to be the most winter storm watches at the same time since 2021 or Groundhog Day 1 or something

Did any of you see northern lights out of this geomagnetic storm?

You are right! But in February 1934, the West was warmer than average. There was a peak wind of 53kt (61mph) at Greeley Airport yesterday and the high winds were close to the Denver area

Denver: warmest December since 1933 Fort Collins: record warmest December

So I guess this is the best storm Toronto has had in a decade. I'm not sure what any Canadian posters may have to say about this. I can't remember them ever boasting about 9.6" in the entire time AmericanWX has existed. and other storm reports of 6"-14.5" near Cleveland, 10"-20" by South Bend

This must be like 1/4 mile visibility, 1" per hour at downtown Cleveland now

It was above freezing not too long ago

no alerts for Toronto. What are they thinking?

my area got to 61 before sunrise, breaking a record of 59

wintertime deluge of rain

snapshot of some (not all) storm reports in a couple hour time frame. 10-12" at Colorado Springs (5-10" in Colorado Springs on CoCoRAHS as of this morning)

no watches/advisories for most areas

10"-20" in 14 days is a lot. It's above the annual rainfall of Colorado every state other than California and North Dakota has drought.

1976-1977 was of course as you mentioned extremely dry for the western USA, and also quite cold and snowy for the Northeast/Great Lakes. This may have been a time when great long-range weather forecaster Namias started noticing the link between El Nino, Pacific SST anomalies, and huge changes in the USA's weather systems. I think this paper says that no low pressure areas tracked through the ridge (at all) around the West Coast. https://journals.ametsoc.org/view/journals/mwre/106/3/1520-0493_1978_106_0279_mcotna_2_0_co_2.xml

I've always thought TDWRs (range of 50 miles/45 nautical miles) aren't too helpful with light precipitation, but radar composite type maps are better.

I thought my place had been chilly for December, but Fairbanks Alaska had -22.8 as the average
