A ridge of high pressure will build over western Montana and north central Idaho this week, bringing another round of warm temperatures to the region. Generally, temperatures will be running 8 to 12 degrees above normal, in the 90s to low 100s. If you will be spending time outside, make sure you drink plenty of water, take frequent breaks, and 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.
