Forecasters with the National Weather Service office in Cheyenne are warning of possible heavy snowfall, poor visibility and colder temperatures with a winter storm that is expected to hit the area Sunday and Monday.

The NWS in Cheyenne has issued the following statement:

Southeast Wyoming:
-Rain will likely change to snow quickly from north to south Sunday afternoon beginning in the Douglas area as early as noon and progressing into the Cheyenne/Laramie areas by late afternoon/early evening.
-Low visibility (1/4 mile or less) and high snowfall rates (1-2 inches per hour) will be possible on Sunday night with possible snow accumulation between 6 and 8 inches for elevations above 5500 ft including Cheyenne, Arlington and Elk Mountain. Laramie could also see some significant snowfall, but there is a possibility they may receive less snowfall due to blocking terrain.
-Elevations above 7500 ft such as the South Laramie Range and the Snowy Range have the potential for around 8-14 inches.
-Temperatures will be colder with this system than with the last one (temps in the 20s), and the timing of the heaviest snowfall being at night make travel impacts more likely.

Western Nebraska:
-Rain may change to snow late Sunday night or early Monday morning over the Nebraska Panhandle.
-Precipitation amounts are expected to be lighter (1-3 inches) and temperatures will be a bit warmer (low to mid 30s).
-Confidence in significant impacts over the Nebraska panhandle is much less at this time, however, some slick roads cannot be ruled out.
