Temperatures are in the mid-sixties this Thursday afternoon in the Steamboat Springs area under partly cloudy skies. Our recent stretch of very nice fall weather is going to be at least interrupted starting on Friday with showers that may extend through Saturday before we see a short reprieve to end the weekend.
An elongated and southwest oriented area of low pressure is currently off the West Coast while another storm is brewing off the Aleutian Islands. The first storm will interact with several waves of upstream energy between the storms, with a couple of cool fronts expected Friday and Saturday afternoons.
Showers are forecast to begin Friday afternoon, perhaps soon after noon, as energy and moisture eject out ahead of the consolidating West Coast storm in increasingly breezy flow out of the southwest. The front is expected later in the afternoon, with showery weather decreasing Friday night.
But more showers are expected on Saturday in advance of a secondary surge of cool air that is forecast to arrive Saturday afternoon. We actually see our favorable moist and unstable flow out of the northwest behind the front, so showers may continue overnight and into Sunday morning as the storm vacates our area.
The weather will clear later Sunday, and Monday should be nice, but that Aleutian Island storm is forecast to mix with air from the North Pole and strengthen as it moves across the Gulf of Alaska during the weekend. I’ll certainly have more on this big weather-maker in my next regularly scheduled weather narrative on Sunday afternoon, but early indications are wet and cold by Tuesday, with snow likely down to the Yampa Valley floor by midweek.
