Workweek to start warm and showery and end cool and showery
Sunday, September 7, 2025
Comfortable temperatures just above seventy degrees, on their way to the mid-seventies, and partly cloudy skies are over Steamboat Springs early this Sunday afternoon. Several weak disturbances in advance of a strong and cold storm well off the coast of northern California will bring a chance of showers to start the workweek, starting this evening. The advancing storm will bring breezy winds and increasing moisture by Thursday, with its eventual track determining how much cold air we see and whether showers linger into next weekend.
A ridge of high pressure is over the Rockies, while a strong and cold storm approaches the northern California coast. Several weak weather disturbances traveling through the ridge of high pressure will bring the chance for showers this evening and overnight, and again later Tuesday, but they won’t affect the high temperatures that are forecast to be just above our seventy-six-degree average.
The cold California storm is forecast to make landfall Monday night before lumbering across the Great Basin through the rest of the workweek. We should see increasing breezes from the south-southwest on Wednesday, with high temperatures being the warmest of the week, and rising to near eighty degrees.
The slowly advancing storm is forecast to push the ridge of high pressure over the Rockies eastward as it traverses across the Great Basin, allowing monsoonal moisture to be drawn northward by winds rotating clockwise around the high pressure. This moisture will be injected into the winds ahead of the cold storm, bringing a good chance for thunderstorms on Thursday and Friday.
The storm is forecast to slow by the end of the workweek before rotating to the northeast, but there is uncertainty regarding the extent of its eastward movement. Weather forecast models have trended toward more of the storm moving through our area, with cooler temperatures and showers lasting into next weekend, but that forecast could certainly change with such a large and wobbly system.
Snow levels could decrease to 11,000′ by Saturday morning if the coldest part of the storm moves overhead, and if moisture can hang around long enough, there may be a dusting of snow on the high peaks of the Zirkels.
Let’s hope the shower chances starting this evening materialize into wetting rains, and I’ll have more details about the Great Basin storm and how it may affect next weekend in my next regularly scheduled weather narrative on Thursday afternoon.
