Chinook

some types of oak leaves I never saw in Colorado, plus some others

There have been scattered of rain showers with a couple of lightning bolts in Chicagoland. (you can see 5 bolt symbols on here if you look closely) It seems like they have the shape of supercells at times, but don't really have noticeable rotation on the SRV radar screen.

Today, temperatures in Colorado are like summer, but sunset at Fort Collins is at 4:52PM, considering the calculation expects a completely flat landscape. Here at my place in Ohio, sunset is at 5:23 Eastern. That feels different, as the solar noon time is pretty much a half hour later at all times. I think it's almost completely based off how the longitude lines up with your time zone. Keep checking the models for a light snow event later this week.

Where are the fantasy snowstorms now? For the GEFS temperature anomalies, there are very few 6-hour periods below normal for me, in the next 384 hours!

Anybody remember this snow storm? It sort of maxed out in and near Cedar Rapids to Madison Milwaukee on 2/6/2008

a good bit of snow has melted at 8000 ft as the RMNP pictures show. I guess the Alpine Visitor Center one hasn't updated in the afternoon. here are some beautiful RMNP pics today with lenticulars east

Some radar images from last night, including the much heavier snow in and around Cleveland. As for me, got about 0.1" or better on grass that stayed until the morning.

How is this not a huge -NAO and huge +PNA

Got the first flakes here, with the radar reflectivy of about 5-10dBz. It kind of proves that radar is pretty bad at picking up snow rates if you are sort of far from the radar. I always called this M.O.C. snow.

This pretty much is the summary of the overall rockies snowstorm

+SN with 1/8 mile measured visibility in western Michigan with this, perhaps, Manitoba Mauler (even though it's not really doing much in terms of winter storm development like the winter)

basically three or four waves of snow hit the Rockies with this upper level trough https://great-lakes-salsite.web.app/Oct_29_2023_loop.html

This upcoming storm is like a vacuum for Europe. This will be a highly negative NAO but the CPC web site says it will only be -1

This should be a good representation of final snow reports. (there are dozens more reports not shown). Values of 5.0-5.5 seem to be at downtown Denver.

Snow bands have shifted around the area all day. I think Fort Collins may have gotten a lot as the snow started early

Estes Park

With response to the Northern Ohio discussion, Toledo had high 79, low 63, average 71 yesterday, all of which were 19, 22, and 21 degrees above normal. 79 broke the record of 78 from 1927, 1984, and 2014. The high of 78 in 1927 must have been a strange one, because there wasn't exactly global warming. Also, 10/28/1927 had a high of 81. 10/27/2014 was fairly similar to yesterday, in the wind directions, and the dew point at Toledo. The similarities are not so much there for the northern Plains, which was in the mid-20's in some areas yesterday.

Here is an image of the revamped aviationweather dot gov web site. It's possible to see the winter storm warning zones, observations, radar, and fronts.

-13C in North Dakota and +17C in Arkansas. With that change of 30 C exactly, the difference of these 850mb temps is 54F. The surface temperatures differed by more than 60 degrees F from central North Dakota to southern Arkansas.

That's weird. You would think that the winter storm watch, replaced by a winter storm warning, would be the normal scenario. That is, for over 8" in 24 hours I believe.

For the snow event: Today's 18z GFS really hits Denver with over 1.0" of QPF. The other models area not too far behind. Generally the models have areas of 0.4"+ for the QPF east of the mountains and maybe quite far east, along I-76.

Oct 23: Toledo was down to 32, first frost of the year Oct 24: Toledo had a near-record high of 81, only one off from the record of 82. So I guess that's like a super Indian summer if we get that close to a record. There are not a lot of leaves that have fallen and covered the lawns. Things seem to be going very well for the red colored maple leaves. Great sunset pic by TheNino! extremely nice leaves here

Hurricane Otis intensified 80mph in 12 hours, from 65mph to 145mph (I actually had no idea this was happening)

The models today have a lot more agreement on the development of snow on the front/jet, as mentioned by Valpovike. A lot of the QPF is similar. Maybe we're back to a somewhat more typical pre-Halloween snowstorm? It seems like the pre-Halloween snowstorm happened on a few years. That 700mb is not warm.

Here is the pattern change coming up. And even in saying this, the GFS and ECMWF have quite different temps for northern Colorado on Oct 26. Nevertheless, the colder air will be in the Northwest and it will move into Colorado at some point. It looks like the models have just light snow for the mountains with the overall system.
