Key Messages
- Seasonably warm and mainly dry into Thursday, with occasional breezy conditions over eastern Montana and light showers in the Absaroka-Beartooth mountains.
- A weather system will likely bring cooler temperatures, windy conditions, and precipitation to portions of the area Friday into Saturday, though confidence remains low on exact impacts.
Aviation
VFR can be expected through the period. A dry cold front will shift winds to the north and northwest late this morning into the afternoon, with easterly winds working into the western foothills, including KLVM. There is a low chance (15% or less) of showers over the Beartooth-Absaroka mountains this afternoon and evening. STP
