As the sun continues moving south of the equator and the northern latitudes cool, the jet stream grows stronger and moves southward. Waves of energy spinning around a large vortex of cool air near Hudson Bay have brought cool temperatures to the upper Midwest and seasonable temperatures to the Steamboat Springs area so far this week.
Our temperatures will rise above our 66 F average starting today and lasting through a pleasant weekend, though we’ll see breezy to windy afternoons, with winds first from the northwest as a surge of cool air slides east of our area along the Front Range on Friday, and then from the west and eventually southwest as a storm off the California coast moves to our northwest on Sunday.
Another Pacific storm appears off the coast of California late in the weekend and conspires with hurricane Rosa, currently south of the Baja coast, to bring likely heavy rainfall to the southwestern quarter of the U.S., including our area, after the weekend.
Different weather forecast models have different ideas on how and when the Pacific storm interacts with the hurricane, though they generally agree that the the hurricane will be absorbed into the southwest flow ahead of the Pacific storm and carried over or near our area around Tuesday or Wednesday. We may see some high clouds later on Sunday, with mid and high clouds moving over our area by Monday, along with some showers possible by later in the day.
There may be a break in the cloud cover before the bulk of of decaying storm Rosa passes near or over our area later Tuesday or Wednesday, bringing possibly heavy rain and flooding concerns over recent burn scars. Unsettled weather is then expected behind the former hurricane for the rest of the work week as the Pacific storm makes landfall midweek and slowly moves across the Desert Southwest.
