Temperatures are moving toward the upper seventies under mostly sunny skies early this Sunday afternoon in the Steamboat Springs area, though clouds are building to our north and south. A weak cool front tonight keeps storm chances around today and Monday before a storm moving across the northern Rockies through midweek brings warm and dry weather to our area starting Tuesday thanks to increasingly breezy winds from the southwest.
Steamboat Springs has been drying out after the remnants of tropical storm Harold dropped around three quarters of an inch of rain over the mountain area and an inch more than that downtown on Thursday and Friday. Friday was particularly drenching downtown as almost one and a half inches of rain fell in the second half of the day. most of which fell over a short period of time around 4 pm as a storm cell moved directly overhead. I’ve heard reports of hail, especially by the middle school, so feel free to share your storm reports from that afternoon by clicking here.
Mountain-top winds have shifted to be from the northwest as the persistent ridge of high pressure that has influenced our weather this summer builds to our west and a storm system approaches the Great Lakes. A weak cool front in that northwest flow will move through this evening, bringing chances for storms later today and overnight. Afternoon storm chances will linger on Monday as high temperatures fall from the low eighties today to the upper seventies tomorrow, which is a couple degrees below our average of 80 F.
Meanwhile, a storm system currently off the Pacific Northwest coast is forecast to be pushed inland on Tuesday by an upstream storm system currently over the Aleutians. As the storm moves across the northern Rockies through midweek, winds will shift to be from the southwest, bringing dry air overhead with high temperatures returning to the low eighties. These winds will increase as the storm system moves across the northern states, with the breeziest days forecast to be on Wednesday and Thursday.
Another storm system dropping along the Pacific Northwest coast late in the work week is forecast to push the western ridge of high pressure back eastward to the Central Plains, and that allows monsoonal flow from the south on the backside of the high pressure to once again move toward our area by as early as Thursday afternoon.
This push of moisture currently looks to be fairly weak, at least initially, though the amount of moisture will ultimately be determined by the development of this next Pacific Northwest storm system. So be sure to check back for my next regularly scheduled weather narrative on Thursday afternoon where I’ll have more details on the weather we may see for the long Labor Day weekend.
