Several cool fronts ahead of end of upcoming week unsettled weather
Saturday, June 8, 2019
Early on this Saturday afternoon in Steamboat Springs, temperatures are running about fifteen degrees below yesterday behind the cool front that passed through last night. Additional mostly dry cool fronts are timed for Sunday and Tuesday, and a moister one on Thursday, after which a stream of Pacific moisture and energy will turn the weather warmer but unsettled, lasting through Father’s Day weekend.
An unseasonably cold storm currently centered over Idaho is located behind ridges of high pressure along the West Coast and northeast North America. Though temperatures will warm today toward our average of 71 F, some Pacific energy moving over the top of the West Coast ridge will force the Idaho storm eastward, and another wave of cool air will sweep over our area on Sunday. High temperatures will be cooler than today, with low temperatures both Sunday and Monday five to ten degrees below our average low of 37 F.
The strong June sun (we are only 2 weeks away from summer solstice, which represents the time of year when the sun is highest in our northern hemisphere sky) will allow temperatures to recover and warm back towards average on Monday before they are knocked back a bit below average again on Tuesday by another dry cool front traveling down the east side of the West Coast ridge.
As the Idaho storm intensifies over the upper Midwest and Canadian Plains, another cool front is forecast to move through our area on Thursday. Additionally, the Pacific energy and moisture that had been riding over the top of the West Coast ridge will pass through and underneath the ridge instead, allowing warmer temperatures and more moisture to move across the West. This pattern looks to persist through Father’s Day weekend and into the following workweek, and would bring increased chances of showers through the period.
