Spot Forecast for Judith Peak Hand Piles...BLM
National Weather Service Great Falls MT
522 AM MST Mon Jan 26 2026

Forecast is based on ignition time of 0800 MST on January 26.
If conditions become unrepresentative...contact the National Weather
Service.

.DISCUSSION...

The primary concern will be gusty west to northwesterly winds
this morning. A decreasing surface pressure gradient should ease
the winds heading into the afternoon hours. Mostly dry conditions
are expected, but a passing weather system will bring increased
cloud cover and perhaps a stray snow shower tonight. Breezy and
dry conditions continue into Tuesday under passing higher level
clouds.
