  1. Mid-Iowa might be the warmest relative to average. Here is some discussion from DMX
  2. 3 out of the top 5 analogs have some version of a severe weather event.
  3. Good news. The Canadian, UK, and ECMWF have shifted back to give Larimer/Boulder counties some snow on Thursday night/ Friday. The GFS still pretty much has small stuff for Denver to Cheyenne. I don't know if this trend will continue. The forecast inconsistency is still pretty annoying for the most populated areas right now.
  4. We've got a December tornado warning on the mid-Mississippi River near Cape Girardeau, MO.
  5. --- and that's why I didn't post a snow or QPF map last night quick temp drop at Greeley, Fort Collins, Loveland, not really lined up with any clouds on the satellite map. My place dropped off from the 60's to the 50's very recently. Edit: Fort Collins dropped from 61.8 to 32.4 in 2 hours. Edit: Loveland mesonet station dropped from 65 to 24 in just this afternoon to early evening.
  6. Loveland, Route 34? It really has been a nice time to get outside and do some walking and jogging, and get going in the morning without having to scrape off a ton of frost or snow. But it does look like winter is coming. Tomorrow, shallow cold front will move in to the I-25 area from the east, and it will stay. The 30-degree cold air mass will be in northeast Colorado for Monday. Most likely, there will be a significant storm at the end of the week. The models have some consensus that the upper level trough will drop down from the Pac NW on Thursday to Utah on Friday, with significant snow possible for Nevada, Utah, northern Arizona, and western Colorado. As for the Plains, today's models have variable predictions of QPF for Larimer County, SE Wyoming, and western Nebraska. That, is, of course, the main question. It is 6-7 days away, so I guess we won't know yet. This upcoming storm will obviously bring a significant increase in snow cover over 9000 ft. and here's something you might not want to see
  7. The models are consistent with a low pressure in Colorado on Tuesday. So far, no models are showing much precipitation. Today's models have a large storm for next Fri-Sat, so that is definitely something that could be discussed over the next week. Today's ECMWF has 987mb near Colorado Springs next Friday and snow at Denver.
  8. Hey, I found something that looks like a moderate snowstorm for Wyoming and the mountains of Colorado.
  9. Of course, it's 70 degrees at a couple of spots around Denver, because it has to be. And it's nice to go outside. After several months of drought in the West, and there's not a cold pattern at all. Upper level trough: minimal. Precipitation: yes, some. Return to warmth: yes.
  10. Today, my area was over 65 degrees after midnight, it cooled down at random times in the morning hours, then got to 70 degrees with scattered clouds/ lenticular clouds. Now it is 50 degrees. I kept looking for a possible lenticular picture, but I have nothing to show for it. I was busy at sunset, which would have been a good time to take a picture. Typical high/low is 53/26. As mentioned by RaindanceWX, the daily SOI value has dropped to a negative value. I have not followed this much, but seems to be correlated with something going on in the subtropical jet stream in several days (10 days?) Maybe hard to get a subtropical something-or-other going during a La Nina. GEFS means show not a whole lot of reason to believe in sustained upper level troughs in the West. Also, not too much QPF by any model in the near future. Well, maybe the 12z Canadian came up with something crazy, but that's about it.
  11. maybe only some very specialized backyard stuff. Otherwise soil moisture is low. I don't think any trees like to do any flowering in November. They could get fooled by weather in March and April, as frost can come after 80 degree temps. Sunset 11/12
  12. Lots happening in the last couple of days. I used the Iowa state local storm report plotter for this, and it appears they have some upgraded software that makes it easy to see multiple snow reports, and distinguish them from rain.
  13. Great post. From my understanding, 11/11/1911 was one of the greatest temperature drops that Missouri has ever seen, accompanied by various tornado reports before the cold front.
  14. Possible tornado Tulsa suburbs, Tulsa Airport Confirmed tornado near I-44/I-244 highways
  15. Models/ensembles now showing some version of a change to colder temperatures around 11/17-11/18.
  16. We're using the GFS, which used to be the parallel-GFS. They were testing out the new computer code, but now it's the operational one. Not sure if there were any bug-fixes which would have made the crazy 30" snowstorms go away. I personally think the models have been all over the place with weather patterns at 7 days+. So good luck trying to find a fantasy snowstorm. There may be some. The two good things about Mountain Standard Time now are: more light at 7:00AM, and the evening models come in 1 hour earlier, so the 00z NAM-12km should be partially done by 7:30PM, 00z GFS, maybe 9:00 and later.
  17. If we could only make some posts about H2O coming out of the air, rather than drought, this discussion would be great. I got my plane ticket to go see my family in Ohio. It is the first time in 2 years. I wonder if Raindancewx can beat the models and tell me if it going to snow when I go on my journeys. Of course, I won't share detailed personal information.
  18. There is an upper level ridge in the West, such that 0C is above 700 mb all over the West, over to California. The 0C isotherm is much closer to sea level in the East. Maybe I should post one of these per day. This is a 3000 mile wide cross section that makes the Rocky Mountains look close to the Appalachians
  19. Toledo had an average temperature 60.6 for the month, so it tied for 3rd warmest October, tying with October 1920. It was the 2nd wettest October, 7.43" of rain, beating October 2001 (6.26".) (I remember October 2001 in Toledo.) Toledo also had its 9th warmest September and 6th wettest September (6.18"). Toledo got 13.61" in September-October (61 days.) This is considerably more rain than Toledo averages over the summer. (92 days)
  20. Temperatures have fallen from 72 degrees on Friday to only a high of 39 degrees this afternoon. That's quite a drop of temperatures, but the cold front was not too interesting. There are a few areas of rain/snow/virga on radar right now. Most areas in northern Colorado could get some very light rain or snow, up to 0.1" in the next couple of days. The northern mountains should get some QPF values of 0.5"-1.0" over the next few days. I have taken a few pictures of lenticular clouds and tree colors. The trees have been nice. Here is a distinct lenticular cloud from 10/22. Longer-term forecasts just mostly have a warm-up, so not too much to talk about. Our area will finish at 2.0-3.0F above average for October, so pretty decently above average. Total precipitation was very low for me, at 0.12" unless some rain shower happens before midnight.
  21. My area had peak wind of 44 kt at the airport today Models show pretty cold on Halloween (Sunday) with snow near Cheyenne and the north border
  22. new confirmed tornado near Sparks, LA (Deweyville TX)
