We’re opening October 2017 on an extreme note with a heavy early season snowstorm for Montana, Idaho, Wyoming and Colorado while summer is making a comeback further east.

An impressive thermal gradient with 20-25 below to the west and 20-25 above to the east…

The depth of trough and cold within sure is impressive for this time of year and so snow totals will likely reach 2-3 FEET.

GFS snow totals through 48 hours.

Upwards of 18″ already down and more to come!

Cold follows the snow

Once the snow clears out and the stars come out, we could see some high snowy plateaus dip close to zero degrees in the coming nights.

Of course further east, summer hangs on…
