mayjawintastawm Posted February 10, 2015 Share Posted February 10, 2015 The persistence of the western ridge/eastern trough pattern we see now is pretty incredible, as is the magnitude of the weather anomalies it's producing on both coasts. I can't recall having such a stuck pattern (really for a year and a half, maybe more) ever. Other than the middle of last year, when we got into the moisture action for a couple months, it's been more or less the same. Any analogs to this that anyone can remember?

ConiferMtnMan Posted February 11, 2015 Share Posted February 11, 2015 We had about 3.5-4" overnight in Pine Junction. While I've been enjoying the warmth, it sure is nice to see some fresh snow! Link to comment Share on other sites More sharing options...
castlerockwx Posted February 11, 2015 Share Posted February 11, 2015 Had 3" just West of Castle Rock. Models are catching on to a possible major front range snow early next week. Things are looking up for winter wx lovers! Link to comment Share on other sites More sharing options...
Chinook Posted February 11, 2015 Author Share Posted February 11, 2015 Fort Collins had a short rain shower in the early morning hours- the grass was wet, not snowy. The models show decent trough energy Sunday-Monday, with increasing QPF in WY/CO on Monday, 00z. Sunday-Wednesday will be quite a cooldown from recent temperatures. There have been some hints of a storm on the 16th of 17th on the GFS/ GGEM for a few days. Link to comment Share on other sites More sharing options...
Chinook Posted February 12, 2015 Author Share Posted February 12, 2015 00z ECMWF (with QPF) shows a pretty big hit for Denver on the 16th-17th Link to comment Share on other sites More sharing options...
newtownwx Posted February 12, 2015 Share Posted February 12, 2015 00z ECMWF (with QPF) shows a pretty big hit for Denver on the 16th-17th Euro is definitely wetter than the GFS for this storm early next week, but I do agree that the potential for a nice, quick hit is there. Looking at the longer range, both the Euro and GFS have been hinting at another system moving through the weekend of the 21st. We desperately need this pattern change.

castlerockwx Posted February 12, 2015 Share Posted February 12, 2015 Canadian is on board with a decent amount of snow for early week. Crossing my fingers that the GFS catches back on and isn't onto something. Link to comment Share on other sites More sharing options...
Chinook Posted February 13, 2015 Author Share Posted February 13, 2015 It would be kind of cool to see the total-accumulated QPF or snowfall for this storm from the ECMWF for the 00z and 12z run today, if anybody has it. Link to comment Share on other sites More sharing options...

Chinook Posted February 13, 2015 Author Share Posted February 13, 2015 The GFS barely shows 0.3-0.4" of QPF for the mountains with these two short-lived snow systems. That is not a lot. As is mentioned below, 3-5" for the foothills in a relatively localized area is pretty weak. SETTING THE STAGE FOR WHAT LOOKS LIKE SEVERAL HOURS OF FALLING TEMPS...GUSTYNORTH-NORTHEASTERLY WINDS AND FROZEN PCPN. THERE IS A POTENTIAL FORSEVERAL INCHES OF SNOW IN PARTS OF THE FRONT RANGE WITH THIS STORMSYSTEM WITH THE COMBINATION OF MOIST UPSLOPE FLOW AND LARGE SCALELIFT PROVIDED BY THE PASSING JET. THIS SETUP WOULD FAVOR THE HIGHERTERRAIN TO THE WEST...SOUTHWEST AND SOUTH OF DENVER WHERE UPWARDS OF3-5 INCHES OF SNOW MAY PILE UP BY MONDAY EVENING Link to comment Share on other sites More sharing options...
boulderrr Posted February 13, 2015 Share Posted February 13, 2015 Ugh this winter is depressing... We were planning to head to Crested Butte next weekend, but are now toying with the idea of just going to the Utah desert instead. The models are suggesting MAYBE something will move in toward the end of next week, so we'll hold off on changing our plans until we find out for sure.

huronicane Posted February 16, 2015 Share Posted February 16, 2015 Snowing pretty good in Northglenn. Hoping to be on the high end of the 4-8" range. Link to comment Share on other sites More sharing options...
Chinook Posted February 16, 2015 Author Share Posted February 16, 2015 We had on and off snow through the day. Although we had some nice flakes and lower visibility, we only got a small coating of snow on the grass. Link to comment Share on other sites More sharing options...
huronicane Posted February 16, 2015 Share Posted February 16, 2015 I'm up to 6+ inches in Northglenn and still snowing nicely. Link to comment Share on other sites More sharing options...
Chinook Posted February 16, 2015 Author Share Posted February 16, 2015 We got an extra 1/2" overnight, and the remaining water froze over, to make slippery roads and sidewalks. I don't think Fort Collins will beat Denver or Boulder in seasonal snowfall. Link to comment Share on other sites More sharing options...
icebreaker5221 Posted February 16, 2015 Share Posted February 16, 2015 Looks like the storm system this weekend has potential. A lot depends upon just how deep that trough digs along the west coast, and how slowly it ejects into the high plains, but certainly potential for heavy snows for both the east slopes and the west slopes.

mayjawintastawm Posted February 17, 2015 Share Posted February 17, 2015 We got about 5" here, maybe more due to melting from the ground up- was at work and not able to do a decent measurement. Ground is warm! Feels like March. Yesterday before it clouded over, went for a run around Cherry Creek lake: iceout was a week ago, and bald eagles, meadowlarks and redwing blackbirds are back. We shall see where we go from here... Link to comment Share on other sites More sharing options...
huronicane Posted February 17, 2015 Share Posted February 17, 2015 Backloaded winter for Colorado this year? GFS and Euro showing a very snowy next week and a half for the state. Link to comment Share on other sites More sharing options...
Chinook Posted February 17, 2015 Author Share Posted February 17, 2015 The 6z GFS shows about 12" for all cities the Front Range over a fairly long period, since the upper trough sits west of us for so long. I expect plenty to change over the next few days. Link to comment Share on other sites More sharing options...

I expect plenty to change over the next few days. Last night's Euro run Just to prevent confusion, the GFS map Chinook showed was just storm #1 (Sat-Mon), while the ECMWF snow map from huronicane includes storms 1 and 2 (mid to late next week). Interestingly, there is pretty good agreement for storm #2 as well for this far out. Link to comment Share on other sites More sharing options...

Chinook Posted February 17, 2015 Author Share Posted February 17, 2015 Colorado local storm reports as of yesterday afternoon-evening. My total was 1-1.5" It was hard to measure because it kept melting. Link to comment Share on other sites More sharing options...

Chinook Posted February 17, 2015 Author Share Posted February 17, 2015 So the 00z ECMWF has some snow at 216-240 hours? That makes some sense off of the 500mb and surface plots. Link to comment Share on other sites More sharing options...

boulderrr Posted February 17, 2015 Share Posted February 17, 2015 We definitely got over 12" in Ned from this most recent storm... Finally had a great day at Eldora yesterday. My wife and I have a dilemma trying to figure out what to do this coming weekend. Our original plan was to go ski Crested Butte on Friday-Saturday, but they haven't gotten snow in a while and it is looking like this storm won't really start hitting them until Saturday, so we'd miss most of the fresh snow. We were also toying with the idea of going to the Utah desert instead, but now it is looking like the drive back on Sunday would be terrible. First world problems, I guess.
