Tomer’s Take

• Sleeper snow hits UT, WY, and CO 3/13-3/14. 2-8″ by early 3/14.
• PNW and B.C. get brunt of storm track and 2-3 different storm systems through 3/20.
• A piece breaks off and hits CA, UT, WY, CO, NM late 3/15 through 3/17.
• Another storm hits CA on 3/19 then moves into the Intermountain West through 3/22.

Tomer’s Take

• If you’re looking for 2-8″ new powder on Monday 3/14 then hit UT, WY, and CO.
• A storm system hits CA on 3/15 then traverses east and hits UT, WY, CO, NM between 3/15-3/18.

Here’s my full analysis for the week ahead:

Tomer’s Take

• Snowstorm for parts of the Northeast on 3/12. Rain/snow line cuts through southern NH, southern ME. Best snow accumulation occurs in VT, northern NH, and northern ME.
• Western storm track shifts 3/13-3/15 into the Pacific Northwest, British Columbia, Idaho, Montana, and Wyoming.
• Then it gradually shifts south 3/15-3/18.
• A “sleeper snow” hits Utah, Montana, and Colorado between 3/13-3/14 with 2-8″.

Skies have cleared in Colorado and mountain air temperatures are running -10 to -25F. Look at this spectacular sunrise view of 14,115′ Pikes Peak. Current summit air temp is -14F.

Northeast 3/12

Notice the rain/snow line slicing through southern NH and southern ME on 3/12. This will cut down on total accumulations.

Tomer’s Take

• Snow continues in southern UT, CO, and NM 3/10 into early 3/11 then drier until 3/13-3/14 when a fast-moving wave of snow delivers 2-8″. That makes 3/14 a powder day.
• The departing storm system from UT, CO, NM will develop into a strong Nor` Easter. Moderate to heavy snow accumulation and strong wind is likely at the major ski areas on 3/12.
• Then the storm track shifts north 3/13-3/16 favoring the Pacific Northwest, British Columbia, Idaho, Montana, and Wyoming. This is a weak atmospheric river setup. Snow levels could get pushed high.
• A larger storm system could hit California on 3/15 then slide into UT and CO on 3/16-3/17.

Northeast Snowstorm 3/12

Notice the rain/snow line cutting through parts of NH and ME on 3/12. The best odds for pure powder are VT, northern NH, and northern ME.

Tomer’s Take

• Snow continues in UT, WY, ID, CO, NM on 3/9 through early 3/11. It’s a powder day across the Wasatch with 10-14″ new in 24 hours. It’s a powder day at Steamboat with 10″ new.
• Then the storm track shifts north 3/12-3/18 into the Pacific Northwest, British Columbia, ID, MT, WY. A weak atmospheric river setup is possible with feet of snow accumulation at Baker, Stevens Pass, Whistler/Blackcomb, and Rainier. Moderate to heavy snow is possible at Schweitzer, Brundage, Red Mountain, Revelstoke, Sunshine Village, Fernie, Big Sky, Jackson Hole, and Grand Targhee.
• We might see a cut-off low traverse UT, CO 3/16-3/18.
• Beyond 3/18, high pressure rebuilds but there are signs of another pressure drop by 3/23-3/26 across the West.

Cut-off Low

A cut-off low pressure system is possible across UT and CO 3/16-3/18. Below, notice the forecast low pressure anomalies valid 3/17.

Beyond 3/18

High pressure rebuilds before another pressure drop across the West 3/23-3/26. Below on 3/24, notice the forecast large ridge of high pressure off the West Coast and lower pressure anomalies across the Intermountain West.

Tomer’s Take

• Snow continues in MT, ID, WY on 3/8-3/9.
• Then snow hits UT, CO, NM late 3/8 through early 3/11.
• High pressure rebuilds briefly.
• Storm track shifts north 3/13-3/18 into the Pacific Northwest (PNW), British Columbia (B.C.), Banff Area, ID, MT, WY. Feet of snow accumulation likely at Whistler/Blackcomb, Stevens Pass, Mount Baker, Mount Rainier. This appears to be a weak atmospheric river setup. Snow levels will have to be watched.
• Only light snow for UT, CO, NM, CA 3/12-3/17.

Beyond 3/17

We might see a cut-off low pressure system around 3/18. This would generate snow and colder temps across the Intermountain West. Below, notice the forecast low pressure anomalies valid 3/18.

Snow Forecast

3/8-3/11:

3/12-3/17:

Northeast, 3/8-3/17:

It now looks like a colder storm hits 3/12 delivering 90% of these totals.

Tomer’s Take

• Next storm system hits MT, ID, WY first then UT, CO, NM between 3/8-3/11.
• This is a colder, more potent storm system versus the previous two storm systems.
• High pressure rebuilds across the Intermountain West starting on 3/11.
• Storm track shifts north into the Pacific Northwest, British Columbia, and Banff Area through 3/15. Snow totals could be significant.
• After 3/15, the storm track could shift south back into the Intermountain West.

Water vapor satellite shows the storm track and storm systems lined-up.

Beyond 3/15

The storm track might shift south into the West after 3/15. Below, notice the forecast lower pressures anomalies valid 3/18. If this occurs then expect snow and colder temps in UT, WY, CO, NM.

Rain/Snow line is a problem with warm temps.

Tomer’s Take

• Storm #1 was largely a bust for Wyoming and delivered lower end totals to Utah (plus some from storm #2). But, we just didn’t see the big 12”+ totals I was hoping for. Storm system was ultimately too warm and gave up pressure battling initial high pressure.
• Storm #2 (currently) is a notch colder and swinging through southern Utah, Colorado, and New Mexico will add some additional accumulation.
• Storm #3 still appears to be the colder, more potent storm system between 3/8-3/11. I’m the most optimistic about this storm out of the three.

Tomer’s Take

• Storm #1 of 3 now affecting the Intermountain West. This storm cycle runs through 3/11.
• Storm #1 is the warmest of the three.
• Storm #2 is a notch colder.
• Storm #3 is the coldest and most potent. It hits the Intermountain West 3/9-3/11.
• Beyond 3/11, high pressure rebuilds briefly.

Beyond 3/12

High pressure appears to rebuild 3/12-3/15 across the West. Below, notice the forecast high pressure anomalies valid 3/15.

Beyond 3/15

The mid-late part of March might turn stormy across the West with lower forecast atmospheric pressure anomalies.

Tomer’s Take

• 3 different storm systems are lined-up for the West through 3/10.
• The first storm system is the warmest of the three.
• The third storm system appears to be the most potent with the coldest air. It occurs 3/9-3/10 across the Intermountain West.
• Beyond 3/11, high pressure might rebuild. See analysis below.

Beyond 3/11
