Light snow returns tonight ahead of cool and unsettled weekend

Wednesday, January 6, 2016

Storms to the south of the Steamboat Springs area have helped eliminate the cold valley temperature inversion we experienced last week into this week as overnight clouds last night have kept the lower elevations relatively warm. A storm currently producing moderate snows in southern Colorado will begin light snow over our area around midnight tonight even as it stays south of our area and moves eastward.

Models indicate a weak TROWAL signature for this storm from about midnight through noon or even afternoon Thursday, and the upward motion associated with this feature is a bit of a wildcard for tomorrow’s snow forecast. With that being said, I would expect around 2-4” for the morning report with the possibility of another 2-4” tomorrow morning if there is indeed enhanced snowfall in the northwest quadrant of the storm due to the TROWAL. There may even be another several inches after noon if the latest bullish forecast from the American NAM model verifies as that model now hangs on to snowfall through Thursday evening.

Another storm further to our south quickly follows on Friday. Current models have this storm too far south to bring significant snows to our area, but a trailing wave phases with some cold air from the Canadian Plains and drags it over our area around Friday night, noticeably cooling temperatures and increasing a moist northwest flow that persists through the weekend.

There should be light to sometimes moderate snow for the entire weekend in this favorable flow as models don’t have the precipitation ending until Monday morning. I would expect around 2-5” of low-density snowfall each day, with only very light snowfall after sunset Sunday.

Monday should be mostly precipitation-free before models indicate some sort of storm moving through the West Coast ridge and possibly affecting our area around Tuesday or Wednesday. There is a great deal of uncertainty with regards to how the West Coast ridge evolves as it is affected by both Pacific energy to its west and very cold air from the Canadian Plains to its east.

Cold valleys and warmer mountains persist through the weekend

Thursday, December 31, 2015

The valley temperature as of 1pm has warmed from a low of -23F to 6F while the summit of Mount Werner has warmed from a low of -7F to 13F under sunny skies. A dry grazing wave mostly north and east of us will drag some more cold air over the Steamboat Springs area later tonight, continuing the below -20F low temperatures for the valley into New Years Day and the day after. Meanwhile, a portion of the West Coast ridge bends over the area, noticeably increasing mountain temperatures by Saturday.

The mountains will warm further through the weekend and into the next work week before a Pacific storm makes landfall in Southern California early Monday, backing our winds to the southwest and likely mixing out the cold valley inversion either during the day Monday or Tuesday.

There may be some light showers by Tuesday afternoon as the weakened storm moves mostly south of our area, but it appears accumulations may be minimal. Another stronger storm follows closely behind, but current forecasts have this storm staying south of our area at the end of the work week as well.

Uncertainty increases by the weekend as the American GFS has another Pacific storm undercutting the West Coast ridge and perhaps phasing with some cold Canadian air while the European ECMWF keeps the weekend storm offshore and the cold Canadian air to our north.

Frigid temperatures in the valley but warmer on the hill

Sunday, December 27, 2015

While the valley is still stuck in just-below zero temperatures after a -20F start to the day, the upper mountain has warmed to 18F as warmer air aloft has moved into the Steamboat Springs area. Monday should be a repeat of today before a dry wave drags some more cold air over the area early on Tuesday, cooling mountain temperatures but ironically bringing some warming to the valley as the strong temperature inversion is moderated.

A series of weak storms from the northwest and north will interact and threaten the area with light snow and continued cold temperatures beginning later Tuesday or early Wednesday. Light fluffy snow will likely fall for all of Wednesday and into Thursday morning before clearing skies should be noted by later in the day Thursday. Depending on when the snow starts, there may be several inches of snow on the hill by Wednesday morning and 3-6” by Thursday morning.

A West Coast ridge typical of recent El Nino episodes forms near the end of the work week, though temperatures will remain cool as the midweek storms are absorbed underneath the building ridge. There is a fair bit of uncertainty for next weekend’s weather as Pacific energy may interact with not only the lingering storm underneath the ridge, but also a grazing Canadian wave containing very cold air.

Last storm in this series arrives for Christmas Day

Thursday, December 24, 2015

After last week’s three foot storm cycle, the 7” mid and 8” up top reported this morning, almost all of which fell during the day Wednesday, leaves the Steamboat Ski Area with another storm cycle total of 35” at mid and 42.5” up top since Sunday night.

After a dry day today, a large storm currently located over the central West Coast will begin to stretch tonight and eventually split by later tomorrow. Energy leading to this split will move over the Steamboat Springs area sometime after midnight tonight and before sunrise tomorrow, likely leading to light falling snow for Christmas morning.

Additionally, the energy moving over our area looks strong enough to form a secondary closed low that will veer our winds from the southwest to the northwest by later in the day, increasing the chances of moderate to sometimes heavy snowfall in the afternoon.

Lighter snows should continue overnight as this secondary low moves east of the area, and may linger Saturday morning. I would expect 6-12” to be reported Saturday morning, with a significant portion of that falling between noon and midnight Friday.

Very cold temperatures will be reinforced for Saturday before warming at higher elevations should be noted by Sunday as the skies clear. Valleys will stay chilly as a temperature inversion reforms after the storm passes.

Monday should stay sunny with pleasant mountain temperatures before a series of weak storms interact and threaten the area with light snow for Tuesday. These storms will drag some more cold air over the region that may be reinforced by another weak storm around Thursday.

Long term models indicate that a Gulf of Alaska or West Coast ridge typical of recent El Nino episodes is likely to form around next weekend, possibly diverting the recent stormy weather around the West and Inter-mountain West.

One to two feet or more likely by Wednesday afternoon

Monday, December 21, 2015

The Steamboat Ski area reported 5.5” this morning and 6” up top, and by 11am an additional 5.5” fell on mid-mountain and 3” up top. After a brief break this afternoon, the snow machine cranks up again tonight as a wet Pacific jet stream takes aim on Colorado. Relatively warm temperatures and very strong westerly winds are expected through midnight as snow starts up again around sunset or early evening tonight.

The winds should moderate sometime after midnight as some cool air moves over the area, but will likely stay strong through the early morning before relaxing and veering more to the northwest by noon Tuesday. Periods of moderate to heavy snow should occur tonight and through the day tomorrow. Including what fell today, I would expect 6-12” to be reported Tuesday morning with at least that much again for the Wednesday morning report.

Snowfall will likely continue at much lighter rates early Wednesday before the final wave in this train, this time in wet but not as windy northwest flow, moves over the area later Wednesday morning, There is some cooler air with the wave, so I would expect lighter density snow during the day before snowfall begins to taper off, but not end, after sunset. I would expect another 4-8” to be reported Thursday morning.

Light snow early Thursday should turn into even lighter flurries or even end for a bit later Thursday before a large and strong storm crosses the West Coast and backs our winds to the southwest on Thursday. The snow from this storm may begin early on Christmas Day as waves eject from the parent low to our southwest and move over the Steamboat Springs area. This storm is currently forecast to last all day, but I expect the forecast to evolve over the next few days as there is a lot going on with the preceding storm.
