Rockies ForecastThe culprit for this is a sharpening southward plunge of the polar jet stream, carving itself out over the Great Basin and Rockies, then getting kicked into the Plains and upper Midwest this weekend.
By late Friday, a changeover to snow should occur as colder air spills south into the Front Range and eastern Plains of Colorado, western Kansas and northeast New Mexico.
Friday Night's Forecast
The heaviest snow totals through Sunday will likely be in the higher elevations of far southern Montana, Wyoming and Colorado. At least 6 inches of wet snow are also possible in parts of the adjacent Plains of Wyoming, western Nebraska, eastern Colorado, far western Kansas, northeast New Mexico and parts of the Oklahoma and far north Texas panhandles.

Snowfall Forecast Through Sunday
Travel along parts of Interstate 25 in Wyoming, from south of Denver to north of Colorado Springs, and south of Walsenburg, Colorado, to Raton Pass, may become difficult. Interstate 90 in northern Wyoming, a stretch of which was shut down earlier in the week, may also become impassable or may close.
Strong north winds, combined with accumulating wet snow, may lead to some downed trees, tree limbs and power outages in areas of heaviest accumulation.
Incidentally, this could be the fourth-latest measurable snowfall on record in Amarillo, Texas, in 86 years of snowfall records, there.
Upper Midwest Phase Late Sunday Into MondayThere's another phase to this system in the Upper Midwest beginning later this weekend.
With low pressure scooting north toward the Great Lakes and intensifying by Sunday, the air will likely become just cold enough on the low's western flank for a swath of wet snow in parts of the northern Plains and Upper Midwest Sunday into Monday – yes, that would be May 1.
