Central Montana has a heat warning through 9:00 p.m. Friday and an excessive heat warning applies to eastern Montana from 10:00 a.m. tomorrow through 9:00 p.m. Saturday. The high temperatures for the next four days (tomorrow, Friday, Saturday, and Sunday) will continue to be in the mid to upper 90s and below 100 in most locations. Fortunately, although it will be hot during the day, we’ll get at least some relief from the heat at night as the lows for the next four nights will generally be in the top 50s and low to mid 60s.
It will continue to be hot at the beginning of next week, although it will be a little cooler than the next few days as the highs will be in the upper 80s and low to mid 90s. It will also remain mild at night next week as the lows in most locations will be in the upper 50s and lower 60s.
Since it will be hot for the foreseeable future, limit your time outdoors during the heat of the day, and if you need to be outside at all, make sure you stay hydrated. wear loose-fitting and light-colored clothing; take frequent breaks in the shade or in the air conditioner; and avoid strenuous activities. Also, make sure you check back in with family members and neighbors regularly to make sure they are safe and make sure you NEVER leave pets or people in a closed car as the temperatures in a car get very hot very quickly can be.
