First Alert 48 Hour Forecast

Air Quality Alert: Smoke will continue to be a health concern through the weekend.

FIRE WEATHER WARNING 2 pm to 9 pm Saturday for our entire region. Wind gusts over 30 mph and isolated dry lightning will produce dangerous fire weather conditions.

Lake Wind Advisory 12 pm to 8 pm Saturday for Flathead Lake. 40 mph wind gusts are possible across the lake Saturday afternoon and evening, producing large waves.

If these alerts didn't tip you off already, another cold front is moving in. The front arrives in Northwest Montana Saturday afternoon and pushes southeast through the evening. Isolated sprinkles and dry lightning are possible as the front moves through. This will be a secondary impact however compared to the 30 to 35 mph wind gusts that will reach across the state during the evening. Highs will reach the 80s.

It will remain breezy with a slight chance of a shower on Sunday; highs in the 60s and 70s.

Cool weather and smoky skies continue next week. Another system midweek will bring us additional chances for rain and wind.
