Behind a weak cool front that passed through Steamboat Springs last night, gorgeous late-summer weather returns this Sunday. This weather will persist into next weekend, though winds will be picking up as the work week progresses.
Currently, a large and cold storm is spinning off the British Columbia coast. This storm will be periodically reinforced with cold air dropping southward from the North Pole, forcing the storm southward and eventually elongating it to the northeast as energy is periodically ejected well north of our area.
The end result is the western third of the U.S. will be caught between the strong storm developing off the West Coast and a building ridge of high pressure over the southeast. Winds will pick up from the southwest as early as Tuesday afternoon, keeping sunny skies and warm temperatures above our 74 F average around that will last through the work week and into next weekend. The clear skies will also allow for efficient nighttime cooling that will drop our overnight lows to around our average 37 F, with the possibility of frost in the low-lying areas of the Yampa Valley.
As mentioned in the previous forecast, hurricane Florence looks to affect at least the mid-Atlantic coast heading into next weekend. This storm may have prolonged effects as it is currently forecast to become trapped under the ridge of high pressure developing over the southeast. It may loiter over the landfall area for three or four days, centered around next weekend, before cold air moving southward from Canada dislodges the hurricane and brings the first freezing temperatures to parts of the northeast.
