Weak storm today followed by typical summer-like weather
Thursday, June 1, 2017
A splitting Pacific storm is currently moving across the Great Basin. While most of the storm will avoid Colorado, increasing moisture and upward motion ahead of the storm will bring good chances for showers to the Steamboat Springs area this afternoon and tonight.
Lingering energy and moisture will fuel the chance of afternoon thunderstorms on Friday as the northern part of the storm moves towards the Great Lakes.
The last forecast discussed the possibility of the southern part of the split possibly affecting our weather on Saturday, but numerical weather forecasts now have that area of low pressure well to the south of northern Colorado. Drier air moves over our region behind the departing northern part of the storm leading to a very pleasant Saturday.
Late in the weekend another storm crosses the Pacific Northwest coast. As earlier predicted by the European ECMWF, a building ridge of high pressure over the Rockies will shunt the slow-moving storm first to our northwest and then to our north. The ridge will be flattened over our area by the grazing storm, and this will lead to a small chance of afternoon storms on Sunday and a better chance on Monday and Tuesday as the airmass is destabilized by cool air aloft associated with the storm.
Temperatures will warm again starting on Wednesday and continuing through the rest of the work week as a ridge of high pressure rebuilds over the Intermountain West behind the grazing storm.
