A broad, diffuse and modestly moist area of low pressure over the southwestern U.S. will keep mostly sunny mornings and a small chance of an afternoon or evening storm around through midweek for the Steamboat Springs area. Drier air then invades the area after midweek behind a storm from western Canada that mostly stays well to our north as it travels along the northern U.S. border.
As has been the case this weekend, the best energy and moisture stays to our south through the coming midweek period. The afternoon and evening storms that do form may produce brief moderate rain for those lucky areas beneath the strongest cells, but they will likely be more windy than wet for the bulk of our region.
A storm from western Canada will travel along the border early in the work week and drag a weak cool front through northern Colorado on Tuesday, similar to the European ECMWF weather model solution offered in last week’s forecast. This will help move the southwestern weather system eastward across Colorado over a couple of days, with Wednesday having the relatively highest likelihood of showers as the tail end of the system moves over our area.
Drier air begins filtering into the area on Thursday, with much drier air advertised for Friday and Saturday. The sunnier afternoon skies and warmer airmass will force daytime temperatures above our 76 F average, but the clear overnight skies will keep lows near our 39 F average for some gorgeous late summer weather.
A fast moving Pacific storm is forecast to cross the northwest coast later Friday and again travel north of our area, though a weak cool front with the possibility of some showers is currently advertised around mid-weekend.
