582 FXUS65 KMSO 101837 AFDMSO Area Forecast Discussion National Weather Service Missoula MT 1237 PM MDT Fri Jul 10 2026 .DISCUSSION... KEY MESSAGES: - Warmest temperatures of the summer for most this weekend through early next week. Elevated heat risk for those sensitive to heat, especially those without cooling or hydration. - Low relative humidity and increased west winds will result in elevated fire weather concerns on Saturday and Sunday, especially in southwest Montana. - Monsoon moisture surge will bring clouds, showers, and thunderstorms by Tuesday. Temperatures will run a few degrees warmer this afternoon (Friday) and will continue to warm as we progress into the weekend. Valleys across western Montana can expect daytime highs in the 90s, while lower elevation areas like Hells Canyon and the lower Salmon River valleys will reach triple digits. Heat Advisories have been issued for the Hells Canyon area and the lower Salmon River valleys in Lemhi County, which go into effect tomorrow and remain in place through Sunday. Moderate heat impacts are expected for valleys along and east of Highway 93, meaning individuals sensitive to heat may be affected. In addition to the heat, strong upper-level winds combined with low daytime humidity will create near-critical fire weather conditions in southwest Montana, with a Fire Weather Watch in place for Sunday. For those recreating outdoors this weekend, please prioritize safety: stay consistently hydrated, take frequent breaks in the shade, avoid strenuous activities during peak afternoon heating, and practice extreme caution to prevent any sparks or fire starts in these dry, windy conditions. A surge of moisture will move into the region from the south, elevating the risk for showers and thunderstorms across western Montana and north-central Idaho, bringing relief from the hot, dry, and windy weekend conditions. The initial shower and thunderstorm activity will bring mostly cloudy skies and erratic, gusty winds due to the very dry air at the surface. By Tuesday evening, the atmosphere will moisten enough for rain to reach the ground. If you have outdoor plans Tuesday through mid-week, plan accordingly. && .AVIATION...VFR conditions with general westerly winds to 10 knots are expected today. A few isolated thunderstorms are possible this afternoon and evening across Lemhi County into southwest Montana, with any developing storms capable of producing strong, erratic outflow winds gusting between 35 and 45 knots. Some high resolution models indicate a slight chance of isolated showers across northwest Montana (including KGPI) overnight tonight. A pattern of hot and dry conditions with increasing afternoon winds will persist through the weekend. && .MSO WATCHES/WARNINGS/ADVISORIES... MT...
