Daily Snow Forecast

Western US

5 hours ago Alan Smith

A low pressure trough will move across the Northern Rockies on Friday & Saturday and abundant monsoonal moisture in place will result in numerous showers & t-storms with heavy rain possible. Scattered t-storms can be expected both days across the Central Rockies, including UT & CO. Early next week, the monsoon will weaken a bit with more run-of-the-mill t-storms & lighter rain for most areas.
