BOZEMAN – A strong pressure gradient is producing strong surface winds across Montana today. A dry cold front is sliding down the jet stream through northern and eastern Montana counties today producing the strong surface gradient.
The combination of warm, dry, and wind will keep fire danger very high to extreme through at least sunset Wednesday. A RED FLAG WARNING is up through 6 pm tonight for most of Montana east of the divide.

Watch for blowing dust, tree limbs falling on power-lines, high profile vehicles will encounter difficult travel conditions especially on I-90 between Butte and Deer Lodge with strong crosswinds.

The next weather maker will be another cold front to impact the state late Saturday. Cooler temperatures and a few showers are possible heading into Sunday and Labor Day.
