Some shower chances to start the week
Sunday, September 28, 2025
Temperatures have fallen from around seventy degrees to the mid-sixties this Sunday afternoon in Steamboat Springs as some thunderstorms passed to our east and west. There is a chance for additional showers this evening as the first part of an approaching storm moves overhead, with the second part bringing less chances for showers on Monday afternoon. Energy ejecting from a large and cold storm now in the Gulf of Alaska will graze our area on Tuesday afternoon for another chance of showers before drier weather appears starting Wednesday and lasts through the workweek.
An eddy that was over central California has moved into Arizona, stretching northeastward into Colorado as a piece of energy ejects from the storm. The rumbles of thunder and shower chances will continue through the evening before resuming again Monday afternoon as the remaining piece of the eddy moves overhead.
Meanwhile, the large and cold Gulf of Alaska storm will rotate towards the West Coast, crossing it on Monday and grazing our area as it is deflected to the northeast by a ridge of high pressure over the Midwest. Tuesday will have another chance of afternoon and evening showers, with high temperatures similar to Monday and near seventy degrees.
Additional upstream energy is forecast to strengthen and stall the original Gulf of Alaska storm over the Pacific Northwest by midweek. Drier air will be carried over our area by southwest winds ahead of the storm, allowing a degree or two of warming for Wednesday and mid-seventies on Thursday.
The Pacific Northwest storm is forecast to move toward our area as additional energy moves through the Gulf of Alaska, though there is weather forecast model uncertainty regarding the speed of the storm. We may see cooler, wetter weather as soon as Friday, or it may be delayed until the weekend.
That will become clearer by my next regularly scheduled weather narrative on Thursday afternoon. Until then, be sure to get outside and enjoy the fall spectacle while there is still good color, as the mid and high-elevation aspen are starting to shed their leaves.
