Chinook

What do you think about this large sector of +2C to +3C in the north Pacific? Will there be a ridge in the Gulf of Alaska for most of the winter?

That is a large area of similarly cold temperatures in the composite. A couple of notes: the last month or so has had a strong ridge in the Southeast and Ohio Valley. I wonder if this will break down this winter or maybe it will continue to pop up and help weather disturbances affect the Upper Midwest, as opposed to Mid Atlantic or Southeast Other note: this looks like a cool snake!

Check this out. There have been some 24" snow reports at Devils Lake, ND.

Now that it has snowed in Denver and this area, we will start the winter discussion for our region. To recap: On Wednesday it was 78 degrees here, but a cold front with 30 mph wind gusts brought the temp to about 39 by evening. On Wednesday night, I saw thunder and lightning with numerous graupel bits which would normally be called 1" of snow. Then, when I got home, there was just a bit of graupel on the ground. Then, Thursday morning, my place got 2" of snow or more. Then, on Thursday evening, there were snow flurries when I was at work. So, I had to go out to my car and clear off another 1/2" of snow off my car. I was wondering if the road would be icy, but I didn't notice anything slippery. Today, things are getting back to being a somewhat normal chilly day.

There has been a 49 to 57 degree temperature drop from 24 hours ago. My area went from 78.4 degrees at about 3:00 or 4:00PM yesterday to 22.1 degrees this morning, but has rebounded to the 30's.

My place got about 2" and we have very light snow now. Denver must have been getting the heavy snow at 9:15AM. Interesting note: there are some synoptic similarities to Oct 30-Nov 3, 1991, which was a large snowstorm on Colorado's plains all the way up to Duluth, where it was a very heavy storm. It was concurrent the "The Perfect Storm" so I like to call it "The Perfect Snowstorm."

Fort Collins had a high of 78 degrees, but it dropped to the lower 40's or upper 30's. As of 1 hour ago, there was graupel, up to diameter of 1/4", that covered the grass up to essentially a snow-depth of 1", with thunder and lightning. I was east of downtown Loveland near Hwy 34 at the time. Now it's 32 degrees.

It's still possible to use Weatherbell.com to look at national NDFD snow forecasts. And this is a big one. I'll be happy with 2" or less on this one. Because 60-70 degrees at this time of year is normal and totally fine with me.

Everybody knows fire and snow don't go together. But maybe they do. Also, the pink for the winter storm warning is close to the magenta for the red flag warning.

What day should we start the Mountain West winter discussion? Leaves are beginning to change. Things are mostly green, but I see some maple trees changing colors these days, as well as some other types. Sunset colors from Oct 5th

I think Fort Collins and Toledo (my old home town) both had their 2nd warmest September in history.

Hurricane force winds measured at the Azores last night

43 knots with gusts to 61 knots at the Azores.

Likely tornado near MKX radar

NWS Cleveland‏Verified account @NWSCLE 2h2 hours ago Record high temperatures at Toledo and Mansfield this afternoon. At Toledo the high of 88 degrees broke the record of 85 set in 2002, 1897 and 1877. While at Mansfield the high of 88 degrees broke the record for today of 85 set in 1953. #clewx #ohwx

Sunset on 9 29 (today) note: record high of 86 degrees today ties a record high from 1933. For the month of September, so far (with 29 days) Fort Collins has tied for the record warmest for September. (67.1 degrees vs a climate normal of 61.5 degrees.)

Apparently there were no tornadoes on Friday, but this is a tornado report at Emden, IL (near Lincoln)

It's always amazing to me to see that storm tops can be nearly -90C in the tropics (Tropical Storm Narda)

A very unusual September heavy snowstorm of 24"+ is likely for Glacier N.P. and Cut Bank, MT.

There may be severe weather in northern Illinois tomorrow night. The models have 3000 J/kg of CAPE with decent shear in W IL, E IA, N MO, at hour 22-24.

Lorenzo has certainly become more impressive in the last 24 hours. It is 20 kts stronger than yesterday morning (11 AM AST) and it is predicted to be a major hurricane Right now it has a couple of pulses of convection near the center, which looks kind of weird. Lorenzo is an Italian name. Maybe he will recurve back to Italy.

There was certainly some Mountain West weather yesterday, with about 14 severe storm reports in the Southwest also. At this time, there is still rainfall around Tucson.

Denver, Colorado is 6.4 degrees above average, 9/1 - 9/19

24-hr precip may have been as much as 9-16" near and southwest of Galveston

Anybody here get over 2.0" near Chicago?
