DISCUSSION

Issued at 217 AM MDT Thu Jun 11 2026

Much of the Snake River Plain and eastern Magic Valley will see temperatures in the upper 20s to low 30s to start with this morning, so a FREEZE WARNING has been continued for the Snake River Plain along with a FROST ADVISORY for the Burley zone. It's a nearly 100% guarantee that all of these highlighted zones will meet AT LEAST frost advisory advisory criteria with the "warmest" temperatures being in Burley and Pocatello at 37 degrees, but it's farther out in the Plain that the colder temperatures will be found. There's a 50 to 60 percent chance that Fort Hall and Blackfoot will fall to 32 degrees or colder with that being closer to a 70 percent chance around Atomic City.

Today temperatures will begin to warm and conditions will be drier for everyone. Highs today will reach the upper 60s in the upper Snake River Plain and low to mid 70s in the lower Snake River Plain and eastern Magic Valley. By Friday afternoon, temperatures will be nearly 10 degrees warmer compared to today. Winds will also be lighter today before breezy conditions return on Friday afternoon with gusts of 20 to 35 mph. Another trough moves into southwestern Montana for the weekend bringing cloudy conditions, which will temper our highs by a few degrees for Saturday and Sunday afternoons. Best precipitation chances are in the Island Park area, but precipitation chances are less than 10 percent currently. Gusts will remain elevated through the weekend.

AVIATION /12Z TAFS THROUGH 12Z FRIDAY/

Issued at 430 AM MDT Thu Jun 11 2026

High pressure building in from the west will bring clear skies and overall light winds for all TAF sites through the period.

FIRE WEATHER

Issued at 12:37 PM MDT Wed Jun 10 2026

Look for drying and warming trends along with breezy conditions today through the weekend. Temperatures will rise back to the 70s and 80s for daytime highs. Min RHs will drop back below 25% for mountain areas and below 15% for the Snake Plain, Eastern Magic Valley and our southwest areas (fire weather zones 410, 425, 427, and portions of 413). Friday and Saturday afternoon winds combined with low relative humidity, higher temperatures, and near critical fuels will bring some renewed at least low-end fire weather concerns to parts of Fire Weather zones 410, 425 and 427. Friday will be the windiest and Fire Weather zone 425 currently has both critical winds and critical relative humidity.
