A RED FLAG WARNING is in effect until 9pm Thursday for a lot of Montana. Hot temperatures, gusty to strong winds, and low relative humidity are going to allow new fire starts and current wildfires to grow rapidly. Please do your part to not start any new fires!
A HIGH WIND WARNING is in effect for Glacier County, Hill County, northern Lewis and Clark County, Liberty County, Pondera County, western Teton County, and Toole County until 9pm Thursday. Sustained wind speeds are going to be between 30 and 40 mph, and wind gusts up to 65 mph are going to be possible at times.

The wind is going to gradually diminish as we go through this evening and the first part of tonight, with just a little breeze around after midnight. It is also going to be cooler tonight than it was last night as lows are going to be in the 50s in most locations. There are also going to be a few scattered showers and thunderstorms around in eastern Montana and eastern portions of central Montana this evening and tonight, mainly before midnight. A couple of these thunderstorms may also be severe with 60+ mph winds. We are also going to have areas of smoke and thicker haze around tonight due to the smoke plumes from the Elmo, Hog Trough, and Moose fires. Outside of the smoke and haze, you can expect partly cloudy to mostly clear skies tonight.
For tomorrow, we are going to have partly cloudy to mostly sunny skies with a slight chance of showers and thunderstorms during the evening around the Helena area. There are also going to continue to be areas of haze and smoke around tomorrow, although a cold front will bring some cleaner air into our area from north to south tomorrow afternoon/evening and tomorrow night.
