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. […]

Update: Labor Day Weekend Mountain Forecast
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 […]
Curveballs: Labor Day Weekend Mountain Forecast and Beyond
Tomer’s Take: In my last update, I highlighted an active weather pattern for Labor Day Weekend and early September across the Intermountain West. The moisture will come in two waves, and you might even say curveballs. The first includes the remnants of a tropical system plus Monsoonal moisture 8/25-8/27, and a Monsoonal surge 8/31-9/2. Beyond […]
Hilary could hammer the Western High Peaks with snow and wind
Tomer’s Take: The remnants of Hurricane Hilary could impact many of the high peaks across the West 8/20-8/21 with strong wind and precipitation including very heavy snow on some California 14ers. This assumes the storm system stays on track. Below, the visible satellite view from GOES-18 shows Hurricane Hilary. I drew on the projected path. […]
What’s Next? End of August and September Forecast Looks Active
Tomer’s Take: Persistent trough is king out West, and this might foreshadow what to expect this El Nino driven Winter. The seasonal Monsoon was three weeks late and intensity was disrupted. It was a victim of larger scale pattern. Lower atmospheric pressures dominate the West Coast through the end of August and then transition into […]
Pattern through July 1; Monsoon Season Preview
Tomer’s Take: The pattern is transitioning across the West. The abnormally wet pattern is moving out while more normal, warmer weather is moving in. This will introduce a drier period for the West until Monsoon Season kicks in. My opinion is that Monsoon Season will start about 1-2 weeks behind schedule. Normal Monsoon Season runs […]
Weekend Mountain Weather, Snow for PNW, July 1 Forecast
Tomer’s Take: An abnormally wet June continues through this weekend across parts of the West with widespread afternoon rain/thunderstorms. A large trough moves into the PNW 6/17-6/21 with high wind and snow for the high Cascades and Volcanoes. Looking down the road, drier weather moves into the West late June through early July with a […]
El Nino is here: What to expect across the West
Tomer’s Take: El Nino has arrived. The triple-dip La Nina is over. Bottom line, El Nino is here through Winter 2024. The La Nina for a generation The 2022-2023 La Nina delivered big time to CA, UT, and CO. In fact, it overdelivered. It overperformed in ways not seen in historical records. It was a […]
Rain totals last 30 days; What’s next?
Tomer’s Take: Parts of Colorado are soaked after record rainfall totals over the last 30 days. Some places are pushing a foot of rainfall. The pattern stays wetter than normal through June 15 then returns to a “normal” precipitation pattern after June 15 through June 30. Denver Front Range Accumulated precipitation May 1 – June […]
Update: Wet June Forecast
Tomer’s Take: May and now June are wetter than normal across parts of the West. I’m forecasting wetter than normal conditions through June 15 then the pattern gradually returns to ‘normal’ precipitation late June. The effects are more pronounced June 20-30 just before the seasonal Monsoon. Precipitation Last 30 Days Percentage of average valid 5/5-6/3: […]
