Heat Advisory

Heat Impacts This Weekend

Pattern Change Early Next Week

A ridge of high pressure will build over central Idaho this weekend (July 12-13), bringing another round of warm temperatures to the region. Moderate heat risk impacts are expected across lower elevations of central Idaho as high temperatures reach into the upper-90s to low-100s. If you will be spending time outside, make sure you drink plenty of water, take frequent breaks, avoid strenuous activity during the afternoon hours. Also, don’t leave children or pets in parked vehicles and be sure to check in on those who are sensitive to the heat, such as the elderly and the very young.

A change to cooler, wet and windy conditions are expected late Monday into Tuesday. Most of the precipitation will be across western Montana with limited rain amounts in north-central Idaho. Gusty north and northeast winds will develop with speeds between 30-40 mph (locally higher gusts in channeled areas of western MT) across the Northern Rockies. High temperatures for western Montana valleys will be in the mid 60s to mid 70s, and mid 80s to mid 90s in north-central Idaho.
