NWS Weather Prediction Center College Park MD
239 AM EDT Sun Oct 02 2022

Valid 12Z Sun Oct 02 2022 - 12Z Wed Oct 05 2022

...Northern and Central Rockies...

Day 1...

Upper-level low lifting northeast from far northwest WY to
east-central MT today resulting in northeasterly flow from MT up
the northern Absarokas, most notably the Red Lodge section in MT
and the Bighorn in WY where up to an additional 4" are possible
above about 9000ft.

SWly flow over CO ahead of a trough rounding the upper low over
the northern Rockies will bring high elevation snow (above about
11,000ft) to the highest San Juan mountains where 4-6" are
possible.


For days 1-3, no icing is forecast.
