21-Hour Epic on the Maroon Bells; Christopher Fish is chasing Andrew Hamilton for the Winter 14er Record

Mountain athlete Christopher Fisher is on the precipice of becoming only the 2nd known person to climb all Colorado 14ers in calendar Winter. The only other known person is Andrew Hamilton who did it 12/21/2017-3/16/2018 (84D13H57M). In a testament to his character, Hamilton is now helping Fisher break his own record. The two stood atop […]

10/21 update: Weekend mountain snow

Tomer’s Take: Pattern change underway. High pressure becomes dislodged. Two low pressure systems lined-up: 10/22-10/24 and 10/26-10/28. Bullseyes: Utah’s Wasatch especially Little Cottonwood, Colorado’s Western/Southwest mountains including Crested Butte, Purgatory, Silverton and Wolf Creek, Montana’s Big Sky and Bridger Bowl. Current Setup The long-standing high pressure ridge becomes dislodged and replaced by both low pressure […]

When will it snow, part 2

Tomer’s Take: Pattern change remains possible on/after 10/23 across the West. Beneficiaries: CO, UT, WY, ID, MT, PNW, Banff. Lower atmospheric pressures replace high pressure ridge. Snow and colder temps = net result. If this verifies it would be the first significant snowfall of the season for much of the Intermountain West. Current Setup Infrared […]

When will it snow?

Tomer’s Take: A large Western ridge of high pressure remains in control through 10/22. A pattern change is possible on/after 10/23. A large dip in the jet stream and lower atmospheric pressures might replace the large Western high pressure ridge. This pattern change might run 10/23-10/27. Net result: snow and colder temps for UT, CO, […]

Golden days of October

Tomer’s take: High pressure remains in control of the West. Mid-atmosphere pressure readings are running 2-3 standard deviations above (higher) the 20-year average. This pattern mirrors the Fall of 2021-2022. When will this change? Some data suggests 10/23. Current Setup Infrared satellite shows the large ridge of high pressure sitting over the Pacific/PNW/West. Crystal clear […]

The snow that wasn’t

Tomer’s Take: Significant snow in Colorado appeared likely based on data a few days ago. Now, that possibility has vanished. Why? It goes to what I talked about in my Winter Forecast: The North Pacific Heat Wave. This warmer than normal ocean water tends to anchor a large dome of high pressure over the PNW/West […]

High mountain snow likely in Colorado this weekend

Tomer’s Take: A series of cold fronts deliver colder air and snow accumulation above treeline Friday, Saturday, and Sunday in Colorado. Below treeline precipitation stays rain. Snow accumulation is possible in all mountain zones above treeline. Some of the biggest totals might occur in the San Juan Mountains. Air temps in the mountains will gradually […]

Gates & Boudreau: Winter Outlook 2022-2023

Tomer’s Take: Meteorologist Cory Gates and Ryan Boudreau released their official Winter Outlook 2022-2023 with heavy focus on Aspen/Snowmass. I featured their outlook last winter and it was incredibly accurate for the Aspen Zone. You can follow and subscribe to their weather updates on I released my Winter Outlook last week. Here’s the full […]

October snow forecast; Fall color update

Tomer’s Take: Two active periods for mountain snow are possible regulated by a ridge of high pressure. Two active periods slightly favor Western Slope zones for higher totals. Best accumulation will occur at higher elevations with melting in-between. Peak Fall color in Colorado is running behind schedule in some mountain zones. My full Winter Forecast […]

Merbok takes aim at Alaska; Weekend events in Colorado

Tomer’s Take: Remnants from Typhoon Merbok to bring 50ft seas and 70mph wind gusts to Alaska. In Colorado, remnants from Kay and a jet streak keep rain/snow and gusty wind going in the Central and Northern Mountain zones 9/15-9/17. Pikes Peak Ascent/Marathon and Run Rabbit Run events occur this weekend. Current Setup Water vapor satellite […]
