Chinook Posted December 29, 2022 Share Posted December 29, 2022 The spotter reports have been 3.0" to 5.5" for many city areas, and higher for Jefferson County. There is a pretty heavy area of snow at Castle Rock, and it seems to be showing the rotation at maybe 700mb if you watch a short radar loop.

mayjawintastawm Posted December 29, 2022 Share Posted December 29, 2022 Just over 4" here at 10 PM, and snowing probably an inch an hour. Super heavy, 10:1 or less. Link to comment Share on other sites More sharing options...
Chinook Posted December 29, 2022 Share Posted December 29, 2022 The western snowpack has been impressive in far west areas. Right now, the Sierra Nevada and Nevada's great basin have the highest percentages. New Mexico isn't getting on the fun. Link to comment Share on other sites More sharing options...
mayjawintastawm Posted December 30, 2022 Share Posted December 30, 2022 10.2" from this storm. Valpovike and Smokeybandit, what did you get? I was surprised it went on as long as it did. Link to comment Share on other sites More sharing options...
Chinook Posted December 30, 2022 Share Posted December 30, 2022 Models from 12z and 18z today have significant snowfall for CO, WY, and NE on January 2nd with a 500mb low developing over Denver. 1 Link to comment Share on other sites More sharing options...

I was out of town a couple decades ago (1995?) when I lived in Eastern PA and they got a record-breaking 2+ foot storm. And roads were closed for days so I couldn't even get back to experience it after! Link to comment Share on other sites More sharing options...
Chinook Posted December 31, 2022 Share Posted December 31, 2022 Lets' go for weenie mode here: The EPS ensemble members max QPF is 0.66" or for Denver, and 1.02" for Fort Collins. These are much higher QPF values than the 12z or 18z GFS. The overall synoptic forecast of the storm has still some questions to be answered for northern Colorado.

jacindc Posted December 31, 2022 Share Posted December 31, 2022 @ChinookAny chance this storm will nudge further north than progged? I'm up near the WY-MT border near Sheridan and it looks like I'll be fringed unless the track reverts to what it had been forecast to do a few days ago.

Chinook Posted December 31, 2022 Share Posted December 31, 2022 Every single model has this being a weak storm for Sheridan. So, sorry. 1 Link to comment Share on other sites More sharing options...
smokeybandit Posted December 31, 2022 Share Posted December 31, 2022 My back yard just got lumped into the winter storm watch. Yet for only 2-5" which seems odd. That's hardly winter storm criteria. Link to comment Share on other sites More sharing options...
mayjawintastawm Posted January 1, 2023 Share Posted January 1, 2023 Who knows about tomorrow, but the snow finally finished melting into my rain gauge, with a whopping 1.6" water from the Wed/Thurs event. No wonder my back hurts. Finished with almost 16" water this year, with more than 10% falling in that 8 hour period this week! Hard to tell exactly, since sublimation and blowing frequently underestimates SWE. Link to comment Share on other sites More sharing options...

ValpoVike Posted January 1, 2023 Author Share Posted January 1, 2023 And a very broad avalanche warning that includes the entirety of the northern foothills. Definitely some questionable watches and warnings today. Link to comment Share on other sites More sharing options...

I wonder how the NWS and organizations with more local expertise like CAIC coordinate- broad warnings are perhaps most useful to raise awareness and drive people to state or local avalanche info sites.

Chinook Posted January 1, 2023 Share Posted January 1, 2023 The Denver NWS web site shows every type of thing you might be expected to see, and an avalanche warning. What's not shown: a winter weather advisory above 6000 ft for Larimer County and Boulder County. I guess they will decide if the north areas are worthy of a winter storm warning or a winter weather advisory later. Link to comment Share on other sites More sharing options...

mayjawintastawm Posted January 14, 2023 Share Posted January 14, 2023 Bumping the winter thread up, last 2 weeks super boring in the Front Range Urban Corridor. Still some glacier left from late Dec. Totals so far: Dec 12.2", Jan 1.3", season to date 23.3". Nothing really on the horizon. Link to comment Share on other sites More sharing options...
ValpoVike Posted January 14, 2023 Author Share Posted January 14, 2023 Yeah a snoozer but seems to happen more often than not in early January. I did spend the week in Santa Clara on business and got the full rain experience. It was crazy. Link to comment Share on other sites More sharing options...
Voyager Posted January 14, 2023 Share Posted January 14, 2023 Gotta ask this here. I moved to Phoenix, AZ this past August from Pennsylvania. I was and still am a frequent poster in the Central PA subforum. Now that I'm out west, is this the best place to discuss Arizona weather, or should I start a thread more oriented to the southwest?

Chinook Posted January 14, 2023 Share Posted January 14, 2023 Today's models have some agreement for Colorado on Wednesday (96 hours). They have a 500mb closed low and surface upslope winds and snow. Link to comment Share on other sites More sharing options...

Chinook Posted January 15, 2023 Share Posted January 15, 2023 On Tuesday to Wednesday, it seems like this could be a longer-lasting storm with several inches of snow. The GFS, Canadian and UKMET have pretty decent QPF of over 0.6" for metro areas, and the 00z ECMWF has lower values. Edit: 12z ECMWF is pretty snowy. Quote .LONG TERM...(Monday through Saturday) Issued at 315 AM MST Sun Jan 15 2023 A series of pacific storm systems will make for an active weather pattern for Colorado this upcoming work week. Will see weak ridging move across the Central Rockies Monday as one system exits the region and another approaches. Even with the ridging, enough pacific moisture will be present for areas of light snow in the mountains. Temperatures are expected to be near normal with highs in the 40s across northeast Colorado. On Tuesday, an upper level trough or possibly closed low moves across the Four Corners region and into western Colorado late in the day. Surface low pressure over southwest and south central Colorado will produce easterly winds across northeast Colorado. This upslope flow will usher in cooler air and moisture. Will see a chance for snow, or possibly freezing drizzle Tuesday afternoon. The mountains will start to see diffluent flow aloft by afternoon. In addition, mid level lapse rates will be steep, 7.5-9 C/km, so heavier snow showers will be possible. Still some uncertainty where the surface low and new upper level low form east of the mountains. Models generally show a band of heavy snow (5-10 inches) forming some where across eastern Colorado. Snow should prevail over much area Wednesday morning if models are on the right track. The snow then shifts eastward and exits during the afternoon and early evening. 1 Link to comment Share on other sites More sharing options...

I don't think Arizona weather is discussed much in the forum (nor is Utah, much) - good opportunity to start a thread, and maybe attract some other posters from AZ! Also, saw that you might be from Tamaqua. Super interesting weather around there with the rain/snow/ice line always nearby... we lived in Allentown and Bethlehem back in the early to mid 90s.
