US Extended Snowfall Outlook
Updated October 20, 2017

HIGH PRESSURE RIDING RETURNS THIS WEEKEND ACROSS THE WEST --> The WEST Coast (+ the resorts) will be sitting under a high pressure ridge, with warmer than average, and sunny weather, after a cold storm on Saturday. CM

LAST DAYS OF OCTOBER/ EARLY NOVEMBER...
High pressure ridging will dominate the eastern US, for a warm-up under mostly sunny skies. Low pressure develops/ deepens across the western US, with colder air and snow likely for western US resort areas again. CM

LONGER RANGE... Around Halloween and in early November, we expect the trough of low pressure to shift back to the western US with some more frequent shots of now much desired snowfall for Colorado. Halloween may be snowy... CM

We put together a comparison to some past possibly analogous years, here: Here is some guidance, using previous similar pattern years. This guidance is for Aspen, near base elevations (mid and upper mountain get 2 to 3 times as much snow).CM
