Mountain Weather 12/13/15

Date: 12/13/2015

We’ll see low level clouds burn off through the day under a fast moving transitory ridge. The next system has already moved onshore over California. A deepening trough bring snowfall back to our mountains starting midday on Monday. Flow will initially be out of the southwest, with the best jet support staying to our south. We should see a few inches during the day on Monday. Cold front passage and more favorable flow arrive Monday evening into Tuesday as the trough closes off and passes overhead. 5″ to 10″ looks like a safe bet by the time this system exits on Tuesday night.

Yesterday’s forecasted storm took some time out of its schedule to slow down and remind weather forecasters who’s boss. No matter, snow is still on its way with snowfall rates picking up at about 3am this morning. Just much later then forecasted yesterday. The sun will rise this morning with a couple inches of new snow on the ground while the heavier precipitation rates will be during the first half of Saturday, mostly before 11am. Some models are still excited for today’s total snowfall with .8” SWE by 5pm. However the Low Pressure trough is currently digging further south than anticipated which is leading to cutting those total snowfall numbers slightly. A weak ridge will be moving into our area this evening leading to a drying trend for Sunday. Winds will be light through today before picking up from the north tonight.

Just when we didn’t think it would ever snow again, the weather forecasts have some interesting changes in store through the start of next week. Currently there is a low pressure trough approaching from the west and a cold front stalling over northern Colorado. A number of weather factors are combining to produce enhanced snowfall numbers north of I-70 and I don’t know if it’s the weather forecasters that are more exited or those locals.

For our area we’ll have to mostly really on orographic snowfall from southwest flow for today’s accumulations. So we should pick up a few inches mainly west of Crested Butte today with continued strong winds from the Southwest. Late this afternoon and tonight we’ll get our share of enhanced snowfall before things start to quiet down as Saturday progresses. Winds will finally start decreasing also on Saturday as the low pressure trough moves over Colorado. A weak high pressure ridge will build as the trough heads east before the next system moves in early next week.

High level clouds and winds will increase under westerly flow ahead of an incoming Pacific system bringing deep moisture. Favorable jet dynamics and a cold front are forecasted to stall over northwest Colorado, leaving us out of the bulls-eye for Friday’s snowfall. The influences of the jet won’t miss us though, with strong to extreme alpine winds at the front end of this system. The cold front then pivots through the Elk Mountains on Friday night, boosting snowfall and pushing our snowfall totals closer to a foot on Saturday in favored locations. A transitory ridge follows behind on Sunday, bringing a lull in weather before another system arrives Monday, bringing continued snowfall.

Mountain Weather 12/9/15

Breezy but dry conditions will persist for the next two days as the storm track and jet stream remains to our north. Weak disturbences embedded in northwest flow will bring increased cloud cover tonight and tomorrow but sno w is unlikely. A Pacifc trough impacts our region on Thursday night into Friday. A slow moving cold front, along with jet and orographic support will combine to produce a decent shot of snow and wind to carry us into the weekend. Accumulations are roughly looking like a foot in favored locations, with half of that or less closer to town.

Mountain Weather 12/08/2015

Date: 12/08/2015

A weak embedded wave under northwest flow will bring an increase in cloud cover and maybe a few snow flurries in our peaks today. We’ll see dry conditions follow suit until another weak disturbance brushes to our north Wednesday night. The heavy hitters arrive on Friday into the weekend, but models are showing some disagreement on how to handle this incoming Pacific trough. Details to come later this week.

Today’s weather will be similar to yesterday with strong valley inversions this morning, slowly easing as the day goes on. High clouds will filter into the area throughout the day as weak ripples in the jet stream bring high level moisture overhead and gusty winds at mountain top level. The weekend’s storm continues to evolve but continue to see model agreement that potential snowfall could range between 10-20” accompanied by strong winds. Each day, and each model run we will see details on timing and strength clarify, so stay tuned.

Our orographic popcorn showers quickly ended shortly after sunset last night in the upper Gunnison River basin, and strong radiational cooling dropped our overnight lows in the valleys to near or below zero, while areas above 10000 feet sit in the 20s at 5am. Sunny skies will dominate today, but look for breezy conditions above treeline. With pretty good model agreement for the week ahead, we can all look forward to a pattern change and significant snow accumulations toward the end of the work week. Yes. The double “S” word…Significant snow… Bears some watching still, but looking promising.

Mountain Weather 12/05/15

Date: 12/05/2015

A fast moving trough and associated cold front are passing over the Elk Mountains this morning, bringing light snowfall and colder air in its wake. Winds are light out of the southwest early this morning, and will swing around to the northwest as this system passes, spurring additional orographic snowfall. A few more inches could accumulate by the afternoon. A short-lived ridge clears and dries out the atmosphere tonight, before zonal flow sets up next week, bringing a series of disturbances, the first of which arrives on Tuesday morning.

Mountain Weather 12/04/15

Date: 12/04/2015

We will see another mild day under warm, southwest flow before a fast moving Pacific trough arrives tonight. Light snowfall kicks off after midnight. We should see 1″ to 3″ before high pressure begins to rebuild on Saturday afternoon. Paradise Divide and Schofield Pass look to be favored for this system.
