5PM 11/27 - Happy Thanksgiving Wyoming and Nebraska! After a mild day on Friday, a strong cold front is expected to sweep through the area. Pre-frontal rain/snow showers will develop in the afternoon in Carbon and Albany counties, but these will be fairly low impact. The cold front will begin to move into the area after sunset, reaching Sidney around midnight. There will be a brief window for numerous snow showers near the cold front. While significant snow accumulation is not expected, snowfall rates may be heavy at times Friday night. This could produce locally hazardous conditions for travellers into early Saturday morning. A few snow squalls will be possible too, mainly between Cheyenne and Rawlins. The graphic attached shows the probability of 1" or more of snow through Saturday morning across the area.
5PM 11/27 - A strong cold front arriving Friday night will bring much colder temperatures into the area through Monday morning. Highs will be stuck in the 20s both Saturday and Sunday. In addition, strong winds will make it feel much colder on Saturday. Sub-zero wind chill temperatures are expected for much of the area both mornings.
Nov. 28th, 4pm - An active weekend and early week is expected across the region with cold temperatures, strong winds, and snow chances. Best chance for snow will be Sunday, with strong to near-high winds possible Tuesday. Less than one inch of snow expected for Sunday, at this time. Mountains could see 6 to 10 inches Sunday.
