Not a bad day across the southern portions of our region. We did have a few snow showers in the eastern highlands and along the continental divide, but they were minimal. 

Tonight, partly cloudy skies with patchy freezing fog. Lows will range from the upper single digits to the low 20's. A very slight chance of snow showers in western Wyoming, but most folks won't see much accumulation. 

Monday - Friday, a stagnant and strong area of high pressure will build over the northern Rockies bringing temperature inversions for most valleys. Daytime highs will range from the low to mid-30's in the valleys with some areas of the higher elevation hitting the mid-40's by the end of the work-week. With the warm temperatures up high, we do expect some melting and the possibility of swollen streams in a few places. Down in the valleys, fog will be the big issue. Expect to see patchy freezing fog almost every night. Later in the week, temperatures could increase just enough to break the pattern, but right now it's not looking too likely.
