smokeybandit Posted February 3 Share Posted February 3 Kind of crazy seeing the models this far apart this close to the storm's onset. Link to comment Share on other sites More sharing options...
mayjawintastawm Posted February 3 Author Share Posted February 3 OK, looking at pivotalweather before bed, 00Z GFS gives me 14", NAM 11", GEFS 9" and SREF 4". Huge differences within 5 miles or so. This is getting interesting. Light rain here now, 41 F. Link to comment Share on other sites More sharing options...
smokeybandit Posted February 3 Share Posted February 3 We just dropped down to freezing as the bulk of the moisture started to come through, so should be all snow from here on out. Link to comment Share on other sites More sharing options...
ValpoVike Posted February 3 Share Posted February 3 A beautiful snow up here, with large flake size. I am already at 3”. My hopes are high! Link to comment Share on other sites More sharing options...
mayjawintastawm Posted February 3 Author Share Posted February 3 Just mixed then flipped from rain to snow here at 5650' as the temp dropped from 35 to 33 in the last half hour. 0.31" rain before the change- more rain than we've seen since October!

smokeybandit Posted February 3 Share Posted February 3 Some nice rates but it looks like the storm will be in and out fast. Link to comment Share on other sites More sharing options...
smokeybandit Posted February 3 Share Posted February 3 About 4" so far. Back end of the storm already well in sight though. Doesn't seem like any more than 2" left Link to comment Share on other sites More sharing options...

Doesn't seem like any more than 2" left I don't know. That band that pivoted west and is pummelling the west C-470 corridor now has to come back east at some point as the energy inches south and east later. 3" here as of 11:30, an inch an hour average. I'm guessing we'll wind up with 8-9" when all is done, you may get 10". Link to comment Share on other sites More sharing options...
smokeybandit Posted February 3 Share Posted February 3 HRRR doesn't have that band getting back east enough to get to me. Looks like it's going to hunker down over I-25 and just west. Link to comment Share on other sites More sharing options...
Chinook Posted February 3 Share Posted February 3 I was going to say that rain above 5000ft at this point of the year is nuts. but I guess it's light snow at Greeley and accumulation in Denver, so that's something Link to comment Share on other sites More sharing options...

mayjawintastawm Posted February 3 Author Share Posted February 3 And now the Mother of All Dryslots is plaguing most of CO except for a very narrow band along the foothills. It's like the storm is 70% dryslot. So weird. 6 inches on the nose, probably 1" WE when you include the rain. Link to comment Share on other sites More sharing options...

mayjawintastawm Posted February 8 Author Share Posted February 8 Nobody's really talking about it, but forecasts have been pretty consistent the last 24 hrs giving much of the Denver metro around 6 inches of snow Friday night through Saturday night.

Chinook Posted February 9 Share Posted February 9 The 18z GFS is kind of splotchy with this one. It's very likely due to high lapse rates/ instability The models have all sort of zones of heavier precipitation with this. I hadn't even been looking at the models much. It looks like the surface temp could be 29. Link to comment Share on other sites More sharing options...

Chinook Posted February 11 Share Posted February 11 Here is the observation in the middle of the night with the heavy snow at Greeley. I would imagine some areas were getting over 1" per hour Link to comment Share on other sites More sharing options...
mayjawintastawm Posted February 12 Author Share Posted February 12 Was away and nobody at home measured, but averaging the two closest COCORaHS sites we'll call it 4" for a total over the two days. that was a weird "storm". Link to comment Share on other sites More sharing options...
Chinook Posted February 16 Share Posted February 16 Here is the precipitation percent of normal and snowfall percent of normal since the beginning of December. From the recent storms, the snowpack snow water equivalent is above normal for the Southwest and below normal for the northern Rockies. Link to comment Share on other sites More sharing options...
