Tomer’s Take: 3-4 storm systems are lined-up through 3/5 for the West. A powerful northern jet and southern jet remain contributing factors. Deep snow accumulation bullseyes remain likely.

31″ in 48 hours at Wolf Creek, CO.

14″ in 48 hours at Kirkwood, CA.

Current Setup

Water vapor shows the almost cut-off area of low pressure moving at snails pace south through the Sierra. It will sit and spin in CA for a couple more days delivering heavy snow before it ejects into the Intermountain West. Additional storm systems are lined-up in a busy Pacific.

Forecast Pattern

Forecast jet stream valid 3/1. An area of low pressure is sliding through the Intermountain West.

Forecast Pattern March 10

Forecast atmospheric pressure anomalies (mid-atmosphere) valid March 10. The West remains active with a signal for lower atmospheric pressures.

Tomer’s Take: The primary ABQ low is moving east. Next up is a snails-pace low in CA nailing the Sierra. This low will sit and spin for a few more days before ejecting into the Southern Tier with snow. Behind it is a 2nd low pressure with wind and snow for the Sierra and the West. 50-100 inch grand totals for the Sierra by 3/4.

104mph gust on Kendall Mountain, CO on 2/22. Wind gusts continue to hover around 100mph on 2/23. Air temps are below zero making the wind chills dangerous.

102mph gust on Wolf Creek Pass, CO on 2/22, early 2/23. Strong wind and below zero air temps continue on 2/23.

Current Setup

Water vapor satellite shows the departing ABQ low and snails-pace low in CA.

Forecast Pattern

Forecast jet stream valid 3/1. A strong storm system ejects out of CA and runs across the Intermountain West with wind and snow.

Tomer’s Take: Heavy snow continues through 3/3 for the West with a powerful jet conveyor belt. A few deep snow accumulation bullseyes continue. The Sierra could see 50-100 inches by 3/3.

Alta, UT is reporting 20″ in 24 hours with more to come!

Jackson Hole, WY is reporting 12″ in 24 hours. This officially puts them over 400″ for the season so far!

Current Setup

Water vapor satellite shows a big trough of low pressure across the West. This sets the stage for additional areas of low pressure to hit the same areas through 3/3.

Forecast Pattern

Forecast jet stream valid 3/1. A large trough and strong storm systems is sliding through CA with heavy snow accumulation.

Forecast Timing

Forecast radar/satellite valid 2/22-2/27.

Tomer’s Take: The main storm system of the period sets up as an ABQ low delivering deep snow bullseyes 2/21-2/22 along with colder air and strong jet wind. Then a cut-off low in CA moves east 2/23-2/26 through the Southern Tier. A third low delivers heavy snow to CA’s Sierra 2/27-3/1.

10″ in 24 hours at Jackson Hole. That makes it 24″ in 72 hours!

Current Pattern

Water vapor shows the main storm system diving south through the Rockies with strong jet support and colder air.

Forecast Pattern

Forecast jet stream valid 3/1. A trough with heavy Sierra snow is moving east.

Forecast Timing

Forecast radar/satellite valid 2/21-2/26.

Tomer’s Take: The Northwest Flow (NWF) is underway and delivering moderate to heavy snow accumulation. Then two storm systems wrangle the moisture and spread it across the West. They also deliver strong northern and southern jet branches plus colder air. After 2/25 it’s a drier waiting game until the next trough hits the west on/after 2/28 into March 2.
