Tomer’s Take: La Nina continues to anchor the pattern across the West through mid-May. It’s the strongest April/May La Nina since 1999. I’m expecting above normal levels of wind, snow, and rain. Across the Intermountain West, a larger dip in the jet stream and trough of low pressure still possible 5/8-5/13. Conditions might ease the […]

Strongest April/May La Nina since 1999
Tomer’s Take: Nino 3.4 region water temps are currently -1.1C. That’s the coldest water temp in this region since 1999. This anchors the atmosphere and the current pattern continues through May. I’m forecasting an active month of May across the Intermountain West with above normal amounts of rain, snow, and wind. The jet stream is […]
Looking back at Winter 2021-2022
Tomer’s Take: Winter started late in many areas with warm/dry weather through most of November and early December. December ended strong in the Sierra and across the Intermountain West with a few moderate to strong atmospheric river (AR) setups. These AR’s hit parts of Colorado hard including above normal snowfall (100″) in Crested Butte. Then […]
Season totals, strong wind, and active early May pattern
Tomer’s Take: The storm track continues to favor the West with a few storm systems lined-up through 5/5. The proximity of the jet stream through 5/5 keeps strong wind in the forecast. Infrared satellite shows the active storm track and storm systems over the Pacific. Season Totals 2021-2022 A few highlights: Alta 440″ Wolf Creek […]
Colorado Dust Storm on 4/22: One for the books
Tomer’s Take: Friday 4/22/2022 was a day for the books. Wildfire danger hit “Very Extreme” for the first time in a decade. Dewpoint and relative humidity values dropped into the single digits. Record high of 89 in Denver. All-time April record is 90. A major dust storm developed as wind gusts reached hurricane force for […]
Weekend snow and wind
Tomer’s Take: Major storm system continues across the West through 4/24 with strong wind and heavy snow at higher elevations. Then the storm track shifts and favors the PNW through the end of April A storm system with snow tracks across MT, ID, WY around April 30-May 1. Infrared satellite shows the storm track and […]
Last gasp of April
Tomer’s Take One last storm major system through 4/24 for the Intermountain West then the pattern shifts favoring the PNW. Precipitation starts as rain in many mountain valleys before changing to snow. Infrared satellite shows the storm track and large Pacific storm system moving into California. The 2nd Pacific storm system takes a more northern […]
Snow and wind through the weekend
Tomer’s Take Western storm cycle concludes with a strong, windy, and slower moving storm system. High to Extreme wildfire risk precedes this storm system. Wind gusts could reach 100mph with blowing dust. A dust layer is possible on the snowpack. After 4/24 the pattern shifts. The storm track moves into PNW and turns more tranquil […]
April snow keeps coming
Tomer’s Take Two storm systems follow a powerful jet stream and deliver heavy snow to parts of the West through 4/24. California’s UC Berkeley Central Sierra Snow Lab is reporting a few feet of snow in the last 7 days. The first storm system is smaller and takes a more northern track and only brushes […]
Weekend snow forecast
Tomer’s Take Two storm systems roll across the West through 4/17. California is finally in the storm track with 2-3 storm systems lined-up through 4/24. 30-70mph wind gusts through 4/17 scrape the high peaks across the West with powerful jet stream aloft. Infrared satellite shows the active storm track for CA and the West with […]
