Nomad Posted October 25, 2011 Share Posted October 25, 2011 We are getting a few tiny raindrops. The foothills are beginning to get hazy/disappear into the cloud deck. Been raining pretty steadily here just west of Englewood since I got home around 4:30 Link to comment Share on other sites More sharing options...

hugo_fran Posted October 26, 2011 Share Posted October 26, 2011 Nice to have you. I just moved here this summer from east TN (Kingsport). Looking forward to the snow as well. Thanks for the welcome! Link to comment Share on other sites More sharing options...

Nomad Posted October 26, 2011 Share Posted October 26, 2011 Just got back from Mount Falcon (7841 feet). It was snowing for the top 200 feet of elevation when I got there around 6, but by the time I was leaving at 6:45 it was snowing like gangbusters and accumulating quickly. It was pure snow down to around 6800 (best guess) and was mixed with the rain down to probably 6200. Can't wait for it to make it down to the city!

boulderrr Posted October 26, 2011 Share Posted October 26, 2011 Gotta be getting close to snow here in Boulder. Temp down to 36.5F in town. We are in a precip lull right now, but it looks like a line is coming up from the south. Link to comment Share on other sites More sharing options...

Dry here on the west side of Englewood right now. More moisture moving in as we speak though. I'd guess 30 more minutes of liquid before we switch to frozen.

RIC Airport Posted October 26, 2011 Share Posted October 26, 2011 Near Monument Hill, nothing much to report at the moment. Had a pretty good rain shower as I was commuting from downtown COS toward the Air Force Academy around 7pm. However, just north of there, it starting snowing. But, nothing falling right now. I'm expecting a good foot here before all is done.....I'll take it! Link to comment Share on other sites More sharing options...

bainbridgekid Posted October 26, 2011 Share Posted October 26, 2011 Snowing here in Boulder now! 33.1F Temperature has dropped ~10 degrees in the last 3 hours. Is it sticking yet? You are going to get a buttload of snow in the next 18 hours. Probably 8-12 inches so this storm will likely be better than anything you had all of last winter. Not bad for October 25th.

baroclinic_instability Posted October 26, 2011 Share Posted October 26, 2011 Beautiful setup for the Front Range with the leading low amplitude northern stream wave and the strong east-northeasterly low level trajectories behind it. The lagging quasi cutoff low and strong mid level westerly flow across the Front Range incites a strong low level mass response and forces even stronger upslope flow. Moistening is enhanced by a robust low/mid level enhancement of the thermal gradient (frontogenesis) followed by continued low level cold air advection with weak damming (although not the classic northerly low level flow with easterly flow over top). The northern branch of the unique dual jet configuration aloft is forcing some pretty impressive mesoscale jet circulations which is further enhancing the low/mid level frontogenesis. Some pretty clear and intense mesoscale bands are setting up north of the Denver metro. Link to comment Share on other sites More sharing options...

baroclinic_instability Posted October 26, 2011 Share Posted October 26, 2011 The dual wave nature shows up much better in PV fields (here the dynamic tropopause on the 1.5 PVU surface). The leading wave is highly responsible for the great east northeast low level trajectories as mass subsidence behind the wave (the CCB aka Cold Conveyor Belt) develops behind the upper PV/shortwave. It is a unique synoptic setup, and we haven't seen it in well over a year. Link to comment Share on other sites More sharing options...

Chinook Posted October 26, 2011 Author Share Posted October 26, 2011 I just drove across town. There is 1 inch on the ground, and 1/2 inch of slush on the streets at least! It really got slushy fast. Wow. Edit: I just had a tree branch almost fall on my house. This could be a bad omen. There are lots more branches that could break. Link to comment Share on other sites More sharing options...

tacoman25 Posted October 26, 2011 Share Posted October 26, 2011 About 1.5" already on the ground in Westminster, with moderate snow at the moment. Maybe .5" on the roads, very slushy. The commute tomorrow is going to be a nightmare. Very impressive banding setting up north of here. Looks like Longmont to Greeley is getting buried right now.

Wow. Edit: I just had a tree branch almost fall on my house. This could be a bad omen. There are lots more branches that could break. This storm is definitely going to cause a huge amount of tree damage. To already see reports of limbs down this early in the game is definitely somewhat disturbing. The combination of trees with lots of leaves and possibly a foot of very heavy wet snow without much wind is going to make things very interesting.
