After two weeks of dry and sunny weather, the pattern has changed and cool air and snow is back in the forecast. 

A complex and very moist storm will push through all of the Rocky mountains, including Idaho, Montana, Wyoming, Utah, Colorado, Arizona and New Mexico. It’s rare that a storm affects the entire mountain range from Mexico to Canada, but this is a special storm due to its breadth and high moisture content. 

Snow will start to fall over all areas (except Arizona and New Mexico) on Wednesday, become heavy on Wednesday night and Thursday, and continue through Friday. For the southern states, the heaviest snow will likely fall Friday through Sunday. 

Total accumulations will easily be 1-2 FEET, with 3 FEET possible in some areas. Due to the high moisture content of the storm, the snow will be a bit thicker and heavier than is normal in the Rocky Mountains, but it’s hard to complain about multiple feet of powder. 

Looking further ahead, two storms are possible during the first full week of February. The first will graze New Mexico on Tuesday, then a stronger system could hit Arizona, New Mexico and southern Utah and Colorado on Thursday into Friday (2/7). 

Enjoy the powder!
