Daily Snow Forecasts

Western US
Cool and wet Northwest, dry and windy Southwest
Updated 5 days ago Alan Smith
The weather pattern will continue to exhibit a La Nina look over the next week with a persistent cool and wet pattern with below-average temperatures across the Northwest with heavy rain and mountain snow. On the other hand, the Southwest (especially New Mexico and Arizona) will continue to deal with warm, dry, and windy conditions which will result in critical fire danger.
Mammoth
May Snow
Updated 6 days ago Mike Korotkin
Cold winter like weather stick around through Wednesday before a prolonged warmer and drier period begins on Thursday. The true spring like and early summer weather will last through most of next week if not longer. Sunny days and warmer temps will be the name of the game...

Final Forecast for 2021-2022
Updated 2 weeks ago Alan Smith
It has been an interesting winter across most of North America with snowy periods interspersed with long dry spells, but April has been colder and snowier than usual for just about all regions. An active pattern will continue across the Northwest & Northern Rockies through the end of the month with snow & rain showers. We also take a look at current snowpack levels and the winter as a whole.
