…and it is going to be huge. I mean it. This is going to be a major rain-maker for the Spokane – Cd’A area that is more typical of the late October – early November rain storms that we get, that can often bring a good base for the mountains. I’m also going to break the forecast up a little differently today because a lot of interesting weather is going on in the mountains in the west. I’ll start with the inland northwest (Selkirk Mountains where Schweitzer is located
MOUNTAIN FORECAST (6,300 feet Above Sea Level)
Weather.com graphic that illustrates the current weather patterns over the lower 48. Note the wet weather approaching the west coast and the stationary/warm front coming out of that low (still in the Pacific, so you can tell it’s huge). Also note the close-together lines that indicate high upper-level wind speed (which could translate to high winds on the ground).
The forecast calls for rain and possibly snow this weekend at Schweitzer Mountain Resort. Here, we see the very moist storm approaching on infrared satellite radar imagery.
Saturday is kind of boring. I’m not being negative, but it is. There’s a 100% chance of thunderstorms at the summit of Schweitzer. No snow yet as this system involves a warm front. Temperatures will be in the lower 40s, so there is a slight chance that some snow will fall Saturday as part of this system. Saturday night yields another night of rain, with a low of 30 degrees. Monday, there is a chance that we could see snow down to the village level (and possibly even lower) with a high of 36, however the chance of snow for both Sunday and Sunday night is 20-30%. Monday is a day of sun and clouds, with a high of 44, but Monday night, there’s a chance of rain with a low of 30 degrees. On Tuesday a high of 43 gives way to a day of a sleet/rain/snow-mix, but Tuesday night is a low of 23 and a chance of snow. Snow remains a possibility for the rest of the week, with highs in the 30s and overnight lows in the 20s.
FOR THE CASCADES AND ROCKIES AS A WHOLE:
Precipitation Forecast from Weather.com for the next 36 hours. Note that the storm will begin as rain and eventually turn to snow in the higher elevations (as in “6-12 new inches for the Cascades this weekend”). Hopefully I’ll update this graphic tomorrow as the conditions change.
Believe it or not, there are winter weather advisories posted in almost every major skiing mountain range in the west (other than Schweitzer and the Selkirks, for the time being). I’ll name them off, briefly – almost every mountain range in the state of Utah, much of the Sierra Nevada, and many mountain ranges in Colorado. Which one is most promising? Personally, I’d say the Alta/Snowbird and Solitude/Brighton (Little/Big Cottonwood Canyons) are going to get the most snow out of this one. The National Weather Service calls for up to
24 inches of new snow accumulation with this system. That makes this storm system more typical of late November or December than anywhere else. To view the full watch while it is still available,
