The National Weather Service offices for the region, have issued a special weather statement, advising that snow is likely in the days to come, in the area’s higher elevations.
A storm system is expected to move across central Wyoming from Thursday afternoon through Saturday. Widespread showers and some thunderstorms are expected ahead of this system Thursday into Thursday night. Only the highest peaks will see snow from the first part of this storm.
However, as a strong cold front moves in late Thursday night, much colder air will be ushered in along with falling snow levels. Widespread rain will continue across the lower elevations while snow levels fall from above 10,000 feet Thursday night, lowering to between 6000 and 7000 feet Friday night and Saturday morning. Significant snow is expected over Bighorn mountains later Friday through Saturday as much colder air moves in and snow levels lower. It`s quite possible that the Big Horn mountains see 4 to 8 inches of snow with over a foot above 10,000 feet during this period.
The lower elevations will see periods of rain during this period, possibly mixing with or changing to snow above 6,000 to 7000 feet late Friday night or early Saturday.
Campers, hunters and other outdoor interests should keep abreast of the latest developments on this first cold storm system of the pre-fall season. Some of the higher trails in the Big Horn mountains could be covered by a significant amount of snow later Friday into Saturday. Pay attention to the latest forecast and plan accordingly.
Freezing temperatures are also possible in the low lying areas Sunday morning behind this system.
