Excessive Heat Watches Issued as Montana Prepares for Weekend Triple‑Digit Heat
Forecasters say the surge will raise wildfire and health risks, raising stream temperatures enough to stress trout.
Overview
- The National Weather Service has issued Excessive and Extreme Heat watches covering eastern Montana and parts of southwest Montana for Saturday and Sunday.
- Sunday is forecast to be the peak with widespread highs in the 100s and some locations east of Billings possibly reaching or exceeding 110°F, while overnight lows may only fall into the 70s and offer little relief.
- Very dry air will push fire danger to high levels and could produce hazy smoke that reduces air quality across the region.
- Sustained daytime heat and warm nights increase risks for children, older adults, outdoor workers and people without reliable cooling and will raise demand on electricity and local cooling centers.
- Forecasters expect the upper ridge to shift east early next week, cooling highs into the 90s Monday and allowing monsoonal moisture to return midweek with renewed chances for showers and thunderstorms; rising stream temperatures during the heat could prompt Montana FWP to issue fishing restrictions.
