Heat Returns June 24-25

Major Pattern Change This Weekend

Temperatures will trend higher through mid-week across the region. Temperatures will hit the low-mid 90s across lower elevations of north-central Idaho, with highs in the 80s in western Montana valleys. These warming temperatures will bring minor to moderate heat impacts across lower elevations of north-central Idaho.

A significant shift in the weather pattern is expected this weekend (June 27-28), bringing much colder temperatures, widespread rain, and high-elevation snow to the region. Confidence is high (>90%) for widespread rain across the area, with over an inch possible across higher terrain and along the divide. Snow levels will fall to near 6,500-7,000 feet by Saturday night into Sunday. High temperatures will be unseasonably chilly, with valleys struggling to get out of the 50s and 60s, while higher terrain will stay in the 30s and 40s. Those with outdoor or recreation plans, particularly in the backcountry, should prepare for a heightened risk of hypothermia and monitor the forecast closely as the weekend approaches.
