huronicane Posted February 23, 2015 Share Posted February 23, 2015 Southern mountains are really adding to the snow pack this weekend and this coming week. Link to comment Share on other sites More sharing options...
Chinook Posted February 24, 2015 Author Share Posted February 24, 2015 Worthy of note: the models have 3 more storms for our area within 240 hours. It looks like a 3-6" storm in the mountains Wednesday, with some 1-3" or spotty snowfall totals in the low elevations. Then Sat-Sun and Tue-Wed of next week might be something to talk about in the next few days. THE NEXT COLD FRONT AND UPPER TROF WILL MOVE OVER COLORADOON WEDNESDAY AFTERNOON WITH DEEPENING MOISTURE AND SOME UPSLOPEFLOW. COULD BE BURST OF MODERATE TO HEAVY SNOW BEHIND THE FRONTWITH STEEP LAPSE RATES AND EVEN SOME SURFACE BASED CAPE. NOT VERYGOOD TIMING AS THIS MAY COINCIDE WITH EVENING RUSH HOUR. AT THISTIME...2-4 INCHES OVER THE URBAN CORRIDOR AND A BIT MORE OVER THEFOOTHILLS. PERSISTENT LIGHT SNOW LIKELY TO CONTINUE THROUGHWEDNESDAY NIGHT AND EVEN ON THURSDAY WITH LIGHT EASTERLY UPSLOPEFLOW AND WEAK QG ASCENT. TEMPERATURES WILL BECOME MUCH COLDERAGAIN FOR THURSDAY AND FRIDAY WITH READINGS ONLY IN THE 20S ACROSSTHE PLAINS.LOOKS LIKE A BRIEF BREAK FROM THE SNOW FOR A TIME FRIDAY ANDEARLY SATURDAY BEFORE THE NEXT SYSTEM AND COLD FRONT DROPS INTOTHE GREAT BASIN ON SATURDAY. MORE SNOW POSSIBLE AGAIN FROMSATURDAY AFTERNOON THROUGH EARLY SUNDAY Link to comment Share on other sites More sharing options...
icebreaker5221 Posted February 24, 2015 Share Posted February 24, 2015 Wow, what an epic pattern for the CO slopes, but especially the southern slopes! That's >12" of snow for about 2/3 of the state, >24" for almost 1/3 of the state, and >48" for a fairly large chunk of real estate over the next 8 days. It's not just GFS, ECMWF looks just as good.

huronicane Posted February 25, 2015 Share Posted February 25, 2015 I'll take it! NAM through Friday morning. Pretty nice snowfall for much of Colorado. Link to comment Share on other sites More sharing options...
boulderrr Posted February 25, 2015 Share Posted February 25, 2015 Hooray for winter finally arriving! I was getting out of shovel-shape. NWS saying there will be a lot of variation in the totals for this storm due to the likelihood of convective snowfall this afternoon into this evening. I'm loving the appearance of this pattern for now. Link to comment Share on other sites More sharing options...
huronicane Posted February 25, 2015 Share Posted February 25, 2015 Posted this back in November. DIA is currently sitting at 40.4", with the NWS P&C for DIA showing 5.4 through Friday, putting us at 45.8, which would be about 11.7" below normal (Disregard the -14.78 in the chart, I am not totally for sure where that number came from now).

mayjawintastawm Posted February 25, 2015 Share Posted February 25, 2015 Likely we'll be in the pink numbers before long, given that we have the snowiest part of winter yet to come. Looks like the left column is total seasonal snowfall and the right is DFN (so average of those seasons DFN gets you the -14.78). Got the shovel out on Sunday... first time in a while! Rust on the snowpile. Link to comment Share on other sites More sharing options...

Chinook Posted February 25, 2015 Author Share Posted February 25, 2015 I don't know how we managed to be one of the wettest places in the country, relative to normal, in the last 90 days. It seems like we had lots of sunshine and warm temperatures. Maybe we had decent water content with the snow that hit us. Note: South Platte drainage basin back up above 100% of normal snowpack.

Chinook Posted February 25, 2015 Author Share Posted February 25, 2015 perhaps moderate snow starting to hit Denver. My area has some light snow now. Link to comment Share on other sites More sharing options...
huronicane Posted February 25, 2015 Share Posted February 25, 2015 It's snowing pretty well in the Denver metro, I'd say moderate to moderate-heavy at times. Link to comment Share on other sites More sharing options...
frontranger8 Posted February 25, 2015 Share Posted February 25, 2015 It's snowing pretty well in the Denver metro, I'd say moderate to moderate-heavy at times. Near whiteout conditions at times driving home from Boulder to Arvada. Already have 2-3" of fresh snow on the ground and the roads are terrible.

huronicane Posted February 25, 2015 Share Posted February 25, 2015 Yep. That is what I am finding on my drive to Northglenn. Shot this video: https://twitter.com/coweatherman/status/570717045664296961 Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
frontranger8 Posted February 26, 2015 Share Posted February 26, 2015 Another heavy band incoming. I've picked up over 4" today on top of the 15" that fell over the weekend. By tomorrow morning, even with compaction I wouldn't be surprised if I have about 2 feet on the ground. Link to comment Share on other sites More sharing options...

Guess somebody goofed. Anyway, got some really heavy snow late this PM, about as heavy as I've seen in my 4+ years here, but so much melted that it only accumulated on the old snow to much of an extent. Got like 2" of slush but about 4" on the old snow. Guess I need a white snowboard to minimize heat absorption- I use an old piece of plywood.

Chinook Posted February 26, 2015 Author Share Posted February 26, 2015 A couple more radar images last night, showing the snow bands that hit Denver. At my house, I got about 1". It barely covered up the grass that was showing, since the snow from Sunday melted in sunny areas. Link to comment Share on other sites More sharing options...
Chinook Posted February 26, 2015 Author Share Posted February 26, 2015 The 12z GFS is showing the 48hr total from Friday morning to Sunday morning (18z-->18z). It shows 2-3" for our area in that 48 hours. Link to comment Share on other sites More sharing options...

huronicane Posted February 26, 2015 Share Posted February 26, 2015 After a slim 2.1" at DIA, they now stand at 42.5" of snow for the season, 7.2" above normal through this point in the year. We were below normal until the active February - 4th most February snow all-time - which has caused some contention on the NWS Boulder facebook page: Link to comment Share on other sites More sharing options...
Chinook Posted February 27, 2015 Author Share Posted February 27, 2015 We got 2" in 4 hours. It is pretty cold now, so the snow ratio is high. This is a surprise to me. I thought last night would be worse than tonight. Link to comment Share on other sites More sharing options...
