Another round of abnormal heat is expected beginning Tuesday and lasting into Wednesday. Above normal temperatures are expected across all of western Montana and central Idaho, but the most extreme temperatures are expected for the lower valleys of northwest Montana (near the Idaho border) and central Idaho. Daytime temperatures into the low 100s with overnight temperatures in the 60s can lead to heat exhaustion or stroke for people who are exposed to the elements. Hot and dry conditions may also lead to increased wildfire activity. Please remember: Do not leave pets or loved ones in parked vehicles.
