Increasing Showers and Thunderstorms

Major Pattern Change This Weekend

Multiple disturbances will bring showers and thunderstorms to the Northern Rockies starting Wednesday and continuing through Friday. On Wednesday afternoon and evening, the focus will be over northwest Montana. By Thursday more areas could see activity and by Friday it will be more widespread in coverage. The main threats will be gusty winds, lightning, small hail and brief heavy rain.

A significant weekend system will bring a stark end to recent warm conditions across the Northern Rockies on June 27-28. Expect widespread rain across the valleys with highs dropping into the 50s and 60s. Above 6,000-7,000 feet, conditions will turn decidedly winter-like with accumulating snow and highs struggling to escape the 30s and 40s. Backcountry recreationists should prepare for an increased risk of hypothermia and raw, wintry conditions.
