Waiting Game: Long Range Outlook

Tomer’s Take

  • Abnormally dry pattern across the West with large high pressure dome through 2/13.
  • One minor, fast-moving cold front races through MT, WY, and CO between 2/10-2/11.
  • 3-day break in precipitation for the Pacific Northwest and British Columbia this weekend as storm track shifts north.
  • Two Alberta Clippers deliver light snow accumulation to the Northeast through 2/13.
  • Snow returns to the Intermountain West around 2/14-2/15, but it appears to be a “one and done” setup.

Waiting Game

The long dry stretch continues across CA, NV, and UT. Cold fronts are forced down the eastern periphery of the ridge through MT, WY, CO, and NM. This is what you might expect during a La Nina phase with some exceptions of course. The latest forecast keeps La Nina in place through Winter then gradually transitions to a “neutral phase” late Spring and early Summer. In the forecast below, negative (colder) anomalies = La Nina.

ENSO model predictions 2/9/2022.

A brief drop in pressures arrive 2/14-2/15, but it’s appears to be a “one and done” setup. High pressure rebuilds through 2/20.

Forecast pressure anomalies valid 2/20, GFS interpretation.

What occurs after 2/20?

The Pacific North American Pattern (PNA) stays lightly negative through 2/24. This suggests an active pattern across the Intermountain West can’t be ruled out. But, it’s not a strong signal.

Tomer’s Take

  • Snow continues early today in NH, ME.
  • Western high pressure keeps snow chances low through 2/13.
  • Minor snowfall with a cold front races through MT, WY and into Colorado’s Central and Northern Mountains on 2/11.
  • More active pattern possible after 2/14 but the signal isn’t major.
  • In the Northeast, Alberta Clippers likely through 2/13.

Long Range

I’m still watching for a more active pattern across the West after 2/14. The change doesn’t look major, the signal might be short-lived, and confidence is middle of the road.

You’re looking at forecast pressure anomalies valid 2/16.

When will the Western High break down?

Tomer’s Take

  • Large Western high pressure blocks all major storm systems from CA, NV, WY, CO, NM through 2/14. Only minor cold fronts race down the eastern periphery through MT, WY, CO, NM.
  • Zero snowfall in CA, NV, UT through 2/14.
  • Pattern could turn more active after 2/14, but genuine pattern change might hold off until 2/18 or later.

I did some backcountry skiing on Saturday. It was windy, cold, and dry. Colorado’s snowpack has flatlined in the last 30 days with only minor amounts of new snow. SWE percentages have declined about 20%.

Backcountry skiing 2/5/2022.

The Setup

Infrared satellite shows the storm track and large Western high pressure dome. Only minor, fast-moving cold fronts will pierce the eastern periphery of the high pressure dome.

Western High Pressure: What’s Next?

The pattern turns more active after 2/14 but genuine pattern change might hold off until 2/18 or later. The forecast below suggests a significant drop in pressures across the West on 2/18. If this occurs then the jet stream would support a colder, snowier pattern.

Forecast pressure anomalies valid 2/7/2022, GFS interpretation.

The Pacific North American Pattern (PNA) agrees. The Euro flips the pattern negative after the 14th. The signal is even stronger after the 18th.

A negative PNA tends to correlate with a more active pattern across the West.

Tomer’s Take

  • Snow continues in the Northeast today with storm skiing. Then it’s a series of Alberta Clippers through 2/13.
  • A fast-moving, minor cold front brushes ID, MT, and WY with light snow between tonight and Sunday.
  • Large high pressure rebuilds across most of the West through 2/13.
  • Possible pattern change after 2/14.

Western High Pressure

Strong high pressure rebuilds across most of the West through 2/13. When will that change? Some data suggest after 2/14. This is one possible scenario with lower pressures returning on 2/15.

Big snow for the Northeast; Western high pressure rebuilds

Tomer’s Take

  • An Arctic front delivers ice and snow to the Midwest then heavy snow to the Northeast 2/3-2/4. Great powder days 2/4 and 2/5 at the major ski areas in VT, NH, and ME.
  • A weak cold front brushes ID, MT, and WY with light snow accumulation 2/5-2/6.
  • Out West, high pressure rebuilds with a long dry stretch setting up for CA, NV, UT 2/3-2/13.
  • Possible pattern change 2/16 or later.

Arctic Front Moves East

Tomer’s Take

  • An Arctic front delivers snow to CO and NM on 2/2. Biggest totals occur in Southern Colorado and Northern New Mexico.
  • This front then drives east with ice and snow for the Midwest and Northeast.
  • The major ski areas in the Northeast start as rain/ice then change to all snow with significant accumulation (10-20 inches) between 2/3-2/4.
  • High pressure rebuilds across CA, NV, and UT through 2/12 with possible larger pattern change by 2/17.

Larger Pattern

High pressure rebuilds across the Intermountain West including CA, NV, and UT through 2/12. This means warmer, drier weather returns.

Forecast pressure anomalies valid 2/12/2022, EURO interpretation.

There is some indication of a larger pattern change around 2/17. Notice across the West the high pressure dome is replaced by lower pressures and a dip in the storm track. This means colder, snowier weather returns.

Tomer’s Take

  • Arctic front delivers snow to MT, WY, ID, CO, NM between 2/1-2/3. Biggest totals occur in CO and NM.
  • This could be the biggest storm of the Winter so far in Northern New Mexico at Taos, Ski Santa Fe, and Angel Fire with 1-2 feet of accumulation.
  • This Arctic front develops into a snowstorm for the Midwest and Northeast 2/3-2/4. Substantial ice and mixed precipitation likely before changing to all snow.
  • High pressure rebuilds across CA, NV, UT between 2/3-2/10 and possibly longer.

First week of February

Tomer’s Take

  • Arctic Front hits MT, WY, ID, CO, and NM 2/1-2/3.
  • This same Arctic Front develops into a storm system for the Northeast Thursday-Friday. Mixed precipitation early then changing to all snow.
  • Looking ahead, high pressure appears to hold strong in CA, NV, UT. Earlier optimism about a pattern change has evaporated.

The Pacific North American Pattern (PNA) has also flipped and is now more positive than negative 2/1-2/10. It trends negative by 2/14.

Nor` Easter; Arctic Front next week Intermountain West

Tomer’s Take

  • Nor` Easter tracking too far offshore to deliver major snow to VT. Favors certain parts of NH, ME, MA.
  • Arctic front hits the Intermountain West 2/1-2/3. Light to moderate snow accumulation followed by a significant drop in air temps.
  • Then high pressure builds and stalls. Problematic for CA, UT, NV.
