BlizzardWx Posted September 29, 2012 Share Posted September 29, 2012 Models today have certainly trended in the right direction for some colder weather slipping in. Maybe even some snow for you guys on the front range. Just colder here but thats better than more heat... Link to comment Share on other sites More sharing options...
Chinook Posted October 1, 2012 Author Share Posted October 1, 2012 I hiked up to 11400 ft today, in Larimer County. I was cold for a while-- 45 to 50 with some 20mph wind gusts. It was a great day to be out there. Link to comment Share on other sites More sharing options...
CharlestonNYC Posted October 1, 2012 Share Posted October 1, 2012 Hiked up by Estes Park today...drizzle and warm at 9K feet. Then drove up trail ridge road to just over 12k feet....into an awesome snow squall and 37 degrees! Was really coming down...so cool. Link to comment Share on other sites More sharing options...

boulderrr Posted October 1, 2012 Share Posted October 1, 2012 I hiked up to 11400 ft today, in Larimer County. I was cold for a while-- 45 to 50 with some 20mph wind gusts. It was a great day to be out there. I was sailing up on Lake Dillon Saturday. It was sunny and in the 60s, but it sure felt cold with the winds gusting above 30kts! It's amazing how low the water is. There are lots of islands that typically aren't there and the gangway to the docks was practically vertical! Link to comment Share on other sites More sharing options...
mayjawintastawm Posted October 1, 2012 Share Posted October 1, 2012 I don't know. Doesn't look like they are tracking precip there anymore. There probably isn't much difference in precip from May-Sep between Stapleton and DIA, since most the storms are convective by nature, hit or miss, and ones further east are often just as heavy as those closer to I-25. However, from October-April, when most of the precip comes from upslope storms, the further west you go, the more precip you get. Which is why Boulder has historically averaged about 20" more snow than Denver. And places out of the plains east and north average about 20" less than Denver. The snowfall difference between the current DEN and Stapleton would probably be around 5-10"/year, I would guess. Yeah, I would agree... the July storms were much heavier for the areas closer to the city, and the ones last week were heavier for DIA by a factor of about 2. May-Sep, they probably all even out. Nice to see spits of snow above 10,000' yesterday. There is a little that has accumulated on the north-facing peaks over 12,000' last week that has stuck around!

BlizzardWx Posted October 2, 2012 Share Posted October 2, 2012 12 GFS shows a good chance of wet snow Friday night. That would be nice for you guys. No moisture here, but much cooler. This reminds me of last winter when we got a lot of cold dry air here but little snow while you guys got blasted. Link to comment Share on other sites More sharing options...
Met1985 Posted October 3, 2012 Share Posted October 3, 2012 Congrats to MT for getting snow in parts of the higher elevations. Link to comment Share on other sites More sharing options...
Chinook Posted October 3, 2012 Author Share Posted October 3, 2012 The 12z GFS shows around 0.10" for Fort Collins and 0.25" for Cheyenne, with almost none in the high mountains. I think this will be mainly light snow on Friday night and Saturday. The Denver NWS discussion seems to say this will not really bring accumulation to low elevations. Looks like the lift is generally from low-level upslope, plus a weak shortwave in Wyoming at the time. We will have 700mb around -5C. This is cold enough for snow, and our surface temperatures will be 30-45 on Saturday. This will be quite a shocker. Link to comment Share on other sites More sharing options...

mayjawintastawm Posted October 3, 2012 Share Posted October 3, 2012 BOU AFD sez measurable snow Friday night for most of the area. Dang. Weren't we complaining about 95+ not long ago???? The leaves around here started changing day before yesterday. That gives us about 4 days of Fall. Wow. Hopefully this'll be a trend... once I get my sprinklers blown out.

marsman Posted October 3, 2012 Share Posted October 3, 2012 Temps plummeting by the minute! Wind has come south into the Denver area. It's also visible on radar. Wundermap really shows the story - upper 70's and calm in the Springs, and 50's for Fort Morgan with wind gusts over 40mph. Link to comment Share on other sites More sharing options...

Chinook Posted October 4, 2012 Author Share Posted October 4, 2012 I drove through a mini-dust storm with wind gusts around 40mph. I haven't seen dirt picked up like that in a long time. Link to comment Share on other sites More sharing options...
famartin Posted October 4, 2012 Share Posted October 4, 2012 Looks like we'll finally get our first freeze out here tonight. Its almost a month overdue (normal is September 10th!) Link to comment Share on other sites More sharing options...
Chinook Posted October 4, 2012 Author Share Posted October 4, 2012 Looks like the NAM is giving Fort Collins about 0.2" of precipitation. This could be 1 to 2 inches of snow on grass surfaces. The GFS has a fair agreement with the precip amounts. NWS CYS has a winter storm watch for part of their area. Looks like the GFS has a small 700mb low near Cheyenne/Laramie at 06z Saturday. This is not a long lasting 700mb low, but it should provide most of the 850-700mb upslope layer for this snow event (as 850mb is upslope the whole time.) The models also have the 500mb vort max moving through central Wyoming and NE Colorado. Link to comment Share on other sites More sharing options...

I'll be surprised if I see more than half an inch of accumulation. Link to comment Share on other sites More sharing options...
BlizzardWx Posted October 4, 2012 Share Posted October 4, 2012 First 30s of the season with a low of 39 last night. We are looking at mid 30s the next few nights, maybe a freeze Saturday morning if we're lucky Link to comment Share on other sites More sharing options...

Chinook Posted October 5, 2012 Author Share Posted October 5, 2012 Nothing interesting here. I see a NWS local storm report of 6" in Sioux County Nebraska, and 3.5" north of Torrington, WY. Link to comment Share on other sites More sharing options...
CharlestonNYC Posted October 5, 2012 Share Posted October 5, 2012 we looked to have gotten about an inch of snow in the speer district of the big D. pretty nice surprise! hopefully tonight/tomorrow will over-perform!! Link to comment Share on other sites More sharing options...
mayjawintastawm Posted October 5, 2012 Share Posted October 5, 2012 Seriously? I've seen it come AFTEr the first snow I have too, but never in the same hour! About 1.25" roughly at our house, though the snow board is still in the garage... estimated from neighbor's car on the street. How's that for official?
