A complex storm currently over the Pacific Northwest this Sunday morning will move over the Intermountain region over the next two days, eventually bringing a couple of cool fronts through the Steamboat Springs area on Tuesday.
The southwest flow ahead of the storm will keep the chance of showers around later today, with short range models indicating the best chance of brief, locally heavy rainfall and possible small hail this evening, and lighter showers later overnight, as energy embedded within the monsoonal flow weakly interacts with the first piece of energy ejecting out of the Pacific Northwest storm.
Winds will increase from the southwest and west on Monday as another piece of the Pacific Northwest storm ejects to our north. It looks like some drier air will infiltrate our area during the day behind the departing wave of energy and ahead of the eastward moving main storm to our northwest, precluding the chance of showers. Some cooler air does look to make into our region overnight on Monday leading to a cool start to Tuesday with low temperatures in the 30’s.
Then, another push of cool air associated with the main storm looks to arrive during the first half of Tuesday, a bit later than indicated in my Thursday forecast. Additionally, there will be some moisture associated with the cool front for a chance of showers on Tuesday before much drier air arrives late in the day or early Wednesday.
If skies clear Tuesday night, Wednesday will start quite chilly, with low temperatures again in the 30’s before a ridge of high pressure is advertised to build over our area for the rest of the work week, bringing warming temperatures and sunny skies heading into the weekend.
Next weekend’s weather will be determined by the evolution of another Pacific Northwest storm, with timing and strength currently uncertain. Right now, my best guess is a relatively dry cool front on Saturday followed by warming temperatures and perhaps and increasing chance of showers by late in the weekend.
