Chinook

There are going to be some Low CAPE/high shear showers and thunderstorms for N. Illinois to N. Ohio. The SPC has a slight risk of tornadoes for the lower Ohio Valley, which is south of the areas just mentioned. Convection-allowing models vary on coverage and placement of rain showers.

Earlier today, this wide-ranging storm system was strung out WNW-ESE across the continent. It's pulling itself apart. Strange U-shaped snow forecast coming up for tomorrow. Also note: the Sierra Nevada is going to get a precipitation total of about 6" (60"+ of snowfall) out of this multi-day weather event.

The storm report says 66mph off the lake, there's got to be a blizzard with that, considering the snow. Superior Wisconsin airport has wind gusts to 53, which also is a high wind. Duluth, max wind gust of 61mph with 1/4 mile visibilty.

There's snow in Fort Collins now. Look how many NWS watches/warnings/advisories there are in the West! There's a fire warning in Kansas. I got a new placefile to put on GRlevel3.

The NWS says generally 12"-18" of snow for the San Juans, and some central areas west of the Sawatch Range. Here is a current picture of Frisco. It looks like summer!

Lake Erie is cracking! It's pretty frozen but showing open spots As of recently, Port Clinton and the islands had temps that were in the single digits like everybody else

For those who use Gibson Ridge products, I found a new way to get placefiles. One of them I found is NWS alert areas (all watches/warnings/advisories) shown on the radar screen https://placefilenation.com/#placefiles

possible tornado(es) near Houston. This one was close to the radar at League City

The sky is red? the other side of the Earth is ON FIRE!

The three weeks from Jan 18 to Feb 7 being the 2nd coldest stretch, and #1 coldest for around Cleveland, Saginaw, a couple spots in Michigan, and some of the Mid-Atlantic. The value of 12.1 degrees F at Toledo is comparable to the 2nd and 3rd coldest months here, Feb 78 and Feb 2015. However, comparing a specific 21-day period to one calendar month is a little bit of comparing apples to oranges. In this case, I guess I would be comparing this 21-day value to a full 28-day long month of February, as mentioned.

I have an unrelated tech question from my previous one I was looking around my computer, and I came upon OneDrive, which I used to use for my job in Colorado. I haven't done a log in since I left my job. I most likely can't do a log in. I don't really want to try. In addition to that, I can see the list of my files, but I can't click on them to do anything. It's like my computer has a list of files that are on a computer in Colorado. But why? I guess most people have a chance to use OneDrive for something other than their job. What if I wanted to do that? Or disable it? I'm not sure.

The AO index has been negative since about Christmas. The AO index isn't calculated based off temperature anomalies, but look at this plot of 1000mb heights over the Arctic Ocean vs Europe. The official calculation of the AO is based on 1000mb height anomalies (close to S.L.P. anomalies,) projected onto a loading pattern and doing the calculus. I would call it a very negative NAO, but the CPC values aren't so negative. And 850mb temperature anomalies in Greenland vs Europe and the USA

If it says "1" it broke a record yesterday

places that broke records yesterday Rapid City: 73 (previous: 63) Casper: 64 (previous:62) Lander: 64 (previous: 61) Billings: 67 (previous: 65) Miles City: 68 (previous: 56) Great Falls: 70 (previous: 62) not Denver, but it was warm anyway Laramie: 55 (previous: 52) Fort Collins: 68.3 on modern thermometer (previous: 68)

The East had a winter. The West had a summer.

7-day departures from normal were -18 to -22 in this area (ending yesterday) with a coldest 1-week period at Orlando, apparently, for these (exact) 7 calendar days

Toledo was 30.25 degrees from Jan 1-16, and 11.3 degrees for Jan 17-31. The average temperature was 21.1 degrees which was 6.4 degrees below normal. Fort Wayne was just 4.2 degrees below normal. (That's kind of because Toledo's climatology is oddly too warm...) The large Greenland blocking toward the beginning of the month was correlated with some warmer temperatures here (as discussed.) Then, the really cold air came in when the ridge developed in/near Alaska. Of course, we ended with a large block west of Greenland that helped the polar air stay over us.

North Carolina completely white on satellite? What is the last time that has happened. I remember the colder winters of 2003, 2010. Maybe those 1/24/2000 should have been a situation where the flatter areas of NC were completely white

I know this is a bit silly, but I think these are a couple of supercells far off the coast

NC radar and some huge 12.5" to 13" storm reports close to Charlotte!

-5 to -20 in eastern Ohio

A long time ago on EasternUSWX, a guy named RaleighWX (I believe) was a meteorology student (or professor) and studied each NC snowstorm. He made a composite of various maps from different times that Raleigh got a snowstorm. I wonder if anybody remembers that. I think he even programmed a model web site for.. EasternUSWX?

kind of looks like a little supercell of snow making landfall at the Outer Banks (no lightning). Already northerly wind gusts to 35-36mph at Cape Fear/Morehead City and 40mph at Piney Island

-40C at 500mb is cold! It's also nearly bottom-tier for ILX (Lincoln, IL) upper-air observations for all time

My loops from the previous storm. I actually saved a lot more data for making a 500mb loop, but I didn't post that. https://great-lakes-salsite.web.app/Jan_23_2026_GFS_surface_loop.html https://great-lakes-salsite.web.app/Jan_24_2026_radar_loop.html
