90‑MPH Chinook Gusts Rake Montana as Warm Spell Precedes Late‑Week Front

A Pacific front is expected to end the warmth late week, with warnings still up along the Rocky Mountain Front as another wind burst looms.

Overview

Confirmed hurricane‑force gusts hit the Rocky Mountain Front, including 93 mph at Bynum Reservoir and 87 mph at Browning, where a trailer was blown over.
High Wind Warnings remain in effect for parts of the Rocky Mountain Front, the western Hi‑Line, and portions of Judith Basin County through late evening and overnight.
Temperatures stayed unusually mild with widespread 50s and 60s, following a day when Great Falls reached 67 degrees to tie the November 10 record.
Forecasters expect a Pacific cold front Thursday night into Friday to knock highs back to near average and to bring valley rain with wet, slushy mountain snow.
Another widespread wind event is forecast Friday, with gusts likely over 60 mph along the Rocky Mountain Front and over 40 mph east of the Front, while a G3–G4 geomagnetic storm could allow aurora viewing tonight into Thursday morning.
