ValpoVike Posted November 14, 2015 Share Posted November 14, 2015 Thanks Chinook!! I have long, long been an obsessive weather observer but I have been lately trying to get into models and such. Your links are really helpful. Link to comment Share on other sites More sharing options...
Chinook Posted November 15, 2015 Author Share Posted November 15, 2015 Update on total 72-hr precip from the NWS/WPC. There's more impressive QPF than I was thinking for the San Juan Mountains and Denver, east I-70, and southwest Nebraska. If that 1.25" is close to accurate for I-70 on the plains, then I imagine a pretty big snow accumulation with the potential for true blizzard conditions there.

mayjawintastawm Posted November 16, 2015 Share Posted November 16, 2015 Wow. 00Z NAM has a snow gradient from 6" to 14" within less than 10 miles, right over me. Front yard and back yard may have different amounts... Link to comment Share on other sites More sharing options...
Chinook Posted November 16, 2015 Author Share Posted November 16, 2015 Blizzard watch has been issued east of Denver and for Castle Rock. NWS BOU weather story, updated http://www.weather.gov/crh/weatherstory?sid=bou&embed=#.Vklbpb_55io NWS GJX weather story also helpful, if you are interested in snow totals for out west http://www.weather.gov/crh/weatherstory?sid=gjt&embed=#.VkldR7_55io Link to comment Share on other sites More sharing options...
skierinvermont Posted November 16, 2015 Share Posted November 16, 2015 First post as new member of Denver metro. Looking forward to my first plains blizzard. 00z suite was impressive and a definite improvement over 12z and 18z. Link to comment Share on other sites More sharing options...

Front yard and back yard may have different amounts... While this could be one of those storms with a strong gradient, I wouldn't put much faith in such fine scale detail, as the horizontal resolution of the NAM is 12 km.

Boards are a lot quieter out here than back east for an incoming snowstorm. Link to comment Share on other sites More sharing options...
ValpoVike Posted November 16, 2015 Share Posted November 16, 2015 Welcome to Denver! What part of the metro area are you in? Boards are a lot quieter out here than back east for an incoming snowstorm. Yes, no doubt. Just the mere mention of Blizzard conditions would result in a 48 page thread in the Lakes or East forums Link to comment Share on other sites More sharing options...
WeatherEmperor Posted November 16, 2015 Share Posted November 16, 2015 Don't see a Blizzard Warning in Denver often. This looks like it is going to be a close call. Just an FYI, I live downtown Denver now, even though my profile says otherwise. Will try to give some spotter reports! Link to comment Share on other sites More sharing options...
Chinook Posted November 16, 2015 Author Share Posted November 16, 2015 Maybe this is turning out to be the big storm for some areas, as was advertised by the GFS, well sort of. The GFS has 1.0 to 2.0" of QPF across the Denver area and Palmer Divide, a pretty large gradient. NAM is slightly above 2.0" for the Palmer Divide and the CO/KS border. That's pretty huge. For those about to shovel, we salute you. Link to comment Share on other sites More sharing options...

Just an FYI, I live downtown Denver now, even though my profile says otherwise. Will try to give some spotter reports! Lots of former VT'ers moving out here it seems. Welcome to the area. I work downtown, but am planning to stay home tomorrow and will also post some reports. Elevation 8,500' but we are in a bit of a snow shadow caused by the mountains near Conifer. Hoping for a good one. Link to comment Share on other sites More sharing options...
cxc292 Posted November 16, 2015 Share Posted November 16, 2015 An east coast transplant myself from Philadelphia. Live on the far eastern side of the metro out by the tollway near southlands. Wondering if this enough in the plains to experience blizzard condition. Will be fun to see this pan out. Link to comment Share on other sites More sharing options...

My guess is yes. Drive on a road you know very well, get perhaps a mile from the nearest building, and see just how scared you get. Better yet, do it at night... :0 Link to comment Share on other sites More sharing options...
boulderrr Posted November 16, 2015 Share Posted November 16, 2015 18Z NAM coming out and seems to be a bit more generous with snowfall amounts for the central and northern foothills versus the 12Z. The Palmer Divide still appears to be the bullseye. Link to comment Share on other sites More sharing options...
Chinook Posted November 16, 2015 Author Share Posted November 16, 2015 We are starting to get a few gusts of 15mph+ here. The cold front will cool us to 40 by about 5pm. 994.0mb at Denver. Lowest barometric pressure here since April. Scattered rain showers in the area. KMNH (Elbert) arleady reporting snow and 37 degrees. Link to comment Share on other sites More sharing options...
salbers Posted November 16, 2015 Share Posted November 16, 2015 I'm watching the local relative humidity as about 50% is a good threshold for it to snow, instead of drying up on the way down. Now up to 40% at Foothills lab in Boulder. Wet bulb is still high enough to start out briefly as rain. http://www.eol.ucar.edu/cgi-bin/weather.cgi?site=fl&period=5-minute&fields=tdry&fields=rh&fields=cpres0&fields=wspd&fields=wdir&fields=raina&units=english Link to comment Share on other sites More sharing options...

Chinook Posted November 16, 2015 Author Share Posted November 16, 2015 Snow is being reported at APA and BKF in the Denver Metro area. So I guess the rush-hour snow problems are starting. Link to comment Share on other sites More sharing options...
ConiferMtnMan Posted November 16, 2015 Share Posted November 16, 2015 Roads already slushy/snow packed on 285 not far from home. Winter Storm Warning amounts upgraded to 10-22" at my place from their old forecast of 8-16". Link to comment Share on other sites More sharing options...

castlerockwx Posted November 17, 2015 Share Posted November 17, 2015 A wet 1"-2" from this afternoon, snow has lightened up in Castle Rock. Hopefully gets cranking as the low approach soon. Hopefully the stroms in KS don't steal our snow! Link to comment Share on other sites More sharing options...

Hopefully the stroms in KS don't steal our snow! snow has moved down the hill to COS/AFF/Falcon/Cheyenne Mountain/Fort Carson. They really have a lot of ASOS locations in the Springs.

WeatherEmperor Posted November 17, 2015 Share Posted November 17, 2015 This storm looks like a bust to me for the denver area itself. I could be wrong, but I'm not feeling the precip / temp setup. Link to comment Share on other sites More sharing options...
Chinook Posted November 17, 2015 Author Share Posted November 17, 2015 It is definitely taking a while to change to snow in most of Denver over to BJC airport and up north to Greeley and Erie. I suppose it could cut back on snow totals. Don't give up yet if you are hoping for snow. 5.0" at Parker with the northerly upslope. Link to comment Share on other sites More sharing options...
