Sunny skies and comfortable temperatures in the mid sixties are over the Steamboat Springs area early this Sunday afternoon. We’ll see warming and dry weather for the upcoming work week except for a small chance of showers later Tuesday. A couple of weak cool fronts are then forecast for Friday and again Saturday, with first westerly and then northwesterly winds increasing as the jet stream grazes our area.
While high temperature today should be around our average of 70 F, they should be in the mid-seventies through midweek. A weak and diffuse wave of energy and moisture will pass by from Monday through Tuesday nights in flow from the southwest, so look for some increasing clouds and the possibility of showers by later Tuesday. But chances for precipitation are low, and like last night, any showers that do form will be light.
Tuesday will also mark the autumnal equinox when, at 7:30 am MDT, the sun passes over the equator on its journey to the southern hemisphere. So while we still be losing daylight everyday through the winter solstice, we will start to lose it more slowly.
Meanwhile, a weak storm currently over the Gulf of Alaska is forecast to be pushed eastward over the work week by a stronger eastward moving storm in the Bering Sea. While both storms will pass to our north, they will be close enough do drag a weak cool front through our area Friday and a stronger one Saturday, similar to the ECMWF forecast from last Thursday’s forecast. Both will be dry, and both will increase the winds, first from the west later Thursday and then eventually from the northwest by Friday night.
Ahead of the stronger cool front on Saturday, temperatures will rise from the mid-seventies on Wednesday to the upper seventies and low eighties for Thursday and Friday. Look for increasing wildfire danger as temperatures soar to much above average along with increasing winds.
While Saturday will likely be the coolest day of the upcoming week, a ridge of high pressure is forecast to build over the West Coast during the weekend, so expect above average temperatures to return under continued dry weather. Longer range weather forecast models continue the warm and dry weather through the following work week, but stay tuned to my next regularly scheduled weather narrative on Thursday afternoon for any changes to that forecast.
