Fall storm to bring colder and wetter weather starting Friday night
Thursday, October 2, 2025
A stunning fall day is over Steamboat Springs this Thursday mid-afternoon, with temperatures in the low seventies and mostly sunny skies. Increasing clouds by Friday afternoon mark a change in the weather, with an approaching fall storm bringing precipitation and cooler temperatures by Friday night that will continue through Saturday, with some snowfall accumulations above 9000′. Behind the storm, precipitation should end by Sunday as temperatures remain cool.
A trough of low pressure extending southward from Vancouver, our incoming fall storm, is moving across the West Coast as a ridge of high pressure extends westward from the East. A separate storm, racing across the Gulf of Alaska, will keep the fall storm moving across California early Friday and the Great Basin Friday night, increasing clouds and breezes over our area by Friday afternoon, but not before high temperatures reach the mid-seventies, almost ten degrees above our sixty-six-degree average.
Energy ejecting out ahead of the storm will start precipitation by Friday evening, with waves of showers continuing through the night in breezy southwest winds. Showers may be spottier Saturday morning, before the cold front associated with the storm passes through around noon, bringing increasing westerly winds, an increased chance of thunderstorms, and lowering snow levels to 9,000′ by Saturday afternoon. We could see several inches of accumulation on the mountain, so be sure to check Steamboat’s Powdercam and Mid-Powdercam for the action.
Temperatures will struggle to reach the sixties on Saturday as the Gulf of Alaska storm moves across western Canada, bringing reinforcing cool air during the day. Lighter precipitation may linger into Saturday evening before winds switch back to the southwest on Sunday, bringing drier air overhead on a similarly cool Sunday.
Temperatures will warm toward average to start the workweek, with partly sunny skies on Monday turning mostly sunny by Tuesday. There may be enough additional reinforcing cold air during the weekend to elongate the southern part of the trough towards Baja, after which there is uncertainty regarding whether an eddy forms and whether a tropical disturbance moves toward our area by the following weekend.
So be sure to take advantage of another couple of the dwindling seventy-degree days left in the season today and Friday, and I’ll have more details on the possible storms for next week in my next regularly scheduled weather narrative on Sunday afternoon.
