- 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 Coast. This in turn affects the jet stream and eventually Colorado’s snow chances.
The West Coast high pressure ridge is significant running 2-3 standard deviations above the 20-year average. Water vapor satellite shows the pattern. Orange/red = drier air aloft.
Taos had some nice early season snow at higher elevations on 10/5-10/6. Taos could see additional light snow late 10/7 into early 10/8.
Colorado’s high peaks have seen a few light snowfalls. Fall color continues. I love this photo from Colorado photographer John Williams.
Photographer Larry Pierce snapped this photo in the Flat Tops on 10/4.
Silverton Mountain in Colorado continued a year tradition with early season skiing at high elevations on 10/2.
The mid-atmosphere pressure pattern through 10/16 suggests the West Coast high pressure ridge maintains its dominance. This effectively limits snowfall in Colorado’s mountains to the light accumulation category. The Front Range of Colorado would stand a better chance at getting hit with fast moving cold fronts.
Forecast total snowfall through 10/16. Only light snow accumulation in Colorado’s mountains.
