Thunderstorms are possible across all of western Montana and north central Idaho on Thursday afternoon and evening. However, the main threat for strong storms is generally along and east of Highway 93 in western Montana and Lemhi County and eastern portions of Idaho county. Strong storms will be capable of winds gusting over 50 mph, brief heavy rain and small hail. If you have outdoor plans Thursday afternoon or evening, especially in the hatched circle, keep an eye to the sky and have a safety plan in place. Also, if you have delicate outdoor objects, consider securing them. Remember, when thunder roars, go indoors!

Abnormally high temperatures will impact the Northern Rockies on Saturday. Forecasted highs for the valleys of north central Idaho and western Montana range from the low 90s to low 100s (lower valleys of north-central Idaho). If you are planning to spend time outside, remember to drink plenty of water, take frequent breaks, and avoid strenuous activity during the afternoon. While the temperatures may be hot, streams and rivers are still running cold and swift, posing the risk of hypothermia. Muddy waters may obscure underwater hazards, so remember to practice cold water safety.
