Breezy winds and temperatures in the upper seventies are over the Steamboat Springs area early this Sunday afternoon with thunderstorms to our north and south. Several disturbances will pass near the northern Colorado border and our area through the work week, continuing the breezy winds and modest chances for showers.
The hot air associated with a flat ridge of high pressure centered over the Desert Southwest is being kept south of our area by a strong-for-early-Augst jet stream extending from the southern Gulf of Alaska across the northern Great Basin and into the central U.S. Our proximity to the jet stream will keep the breezy winds around for the work week as several Pacific waves embedded within the jet stream, in addition to waves rotating around the northern periphery of the ridge of high pressure to our south, periodically move through the area.
While afternoon heat may lead to thunderstorm activity, the upward motion associated with these waves can also support the storms, as evidenced by the last several days of nocturnal, or overnight, thunderstorms in our area.
It looks like we will have modest chances of showers later today through about Wednesday morning, including possibly overnight, as these waves periodically pass near our area. These showers are not likely to produce a lot of rain, though brief locally moderate rain and gusty winds are possible with any of them.
High temperatures look to remain around eighty degrees today and Thursday, several degrees below our average of 83 F, with slightly cooler temperatures in the mid to upper seventies through midweek thanks the cooler air and clouds associated with the waves.
Dry weather with more of the same comfortable temperatures look to close out the work week and start next weekend, though we may start to see some moisture returning during the middle of the weekend associated with a possible return of the monsoon, as well as a tropical disturbance bubbling up from Baja. So be sure to check back Thursday afternoon for my next regularly scheduled weather narrative where I’ll highlight the weather for the coming weekend.
