Tomer’s Take: The first of three cold fronts moves across the Banff, MT, WY today (10/23). The two remaining cold fronts are more significant 10/24-10/29 with additional jet stream support and colder air. Colorado remains abnormally warm until 10/28 when the 3rd cold front arrives.

Tomer’s Take: A storm system with snow for UT, WY, CO hits 10/11-10/12 along with a 15-30 degree temperature drop. The track of the storm continues trending slightly further north into WY. This has increased forecast totals for WY and parts of UT. The mountain towns of Aspen and Vail start as rain then change […]

Tomer’s Take: A strong cold front with snow for CO, UT, WY is still on track between 10/11-10/12. Storm track has shifted a little north pulling the bigger CO totals a little further north. Light to moderate accumulation in UT, moderate in WY (exception is Hogadon Basin and Snowy Range with heavy snow coming), with […]

2 Comments on Cold Front Delivers Snow to CO, UT, WY 10/11-10/12

Tomer’s Take: A dip in the jet stream delivers a strong cold front and area of low pressure to Colorado, Utah, and Wyoming between 10/11-10/12. Light accumulation in Utah and Wyoming. Heavier accumulation in Colorado (4-8″). Air temps drop 15-30 degrees. The bulk of the snow accumulation in CO stays above 10,000ft in the Central […]

13 Comments on Winter Forecast 2023-2024

Tomer’s Take: A Strong El Nino is likely with a screaming Subtropical Jet across the Southern Tier by January, February, March, April, and May 2024. I believe we’ll see a 30% El Nino Modoki contribution. This puts several major ski resorts on ‘The Bubble’. Atmospheric River (AR) setups are likely along with large East Coast […]

Tomer’s Take: It’s a busy weekend ahead for athletes with both the Pikes Peak Ascent/Marathon and Run Rabbit Run 50/100M. Both events will have weather impacts early in the weekend, drier later. I’m forecasting new snow accumulation above treeline on 9/14 and 9/15 with a cold front and active Subtropical Jet Stream. Pikes Peak Summit […]

4 Comments on Snow on Colorado’s 14ers with More to Come

Tomer’s Take: The first snow of the season is covering some of Colorado’s 14ers including Longs Peak. Additional snow accumulation is likely through 9/15. 14er summit temps are now falling into the teens and 20s. Why? An enhanced Subtropical Jet Stream plus remnant moisture from a hurricane. I also include a forecast for the Run […]

2 Comments on Foreshadowing Winter: Rain/Snow with Subtropical Jet hits Colorado 9/10-9/15

Tomer’s Take: Rain/Snow appear likely for parts of Colorado between the afternoon of 9/10 and 9/15. The 14ers could see snow accumulation. Why? The Subtropical Jet is back plus it will entrain some of CAT-5 Jova’s moisture. Remember it from May, June and early July? This is a foreshadowing of what to expect this Winter. […]

Tomer’s Take: A dip in the jet, trough of low pressure, and small surge of Monsoon moisture remains in my forecast for the West between 9/1-9/5. I say 9/5 now because there might be one additional small area of low pressure riding the coattails. This pattern delivers cooler mountain temps and rain/snow/thunderstorms. Snow accumulation appears […]
