BOZEMAN – The weather pattern over Montana through the long holiday weekend is a little complex with a weak Canadian cold front dropping down into Montana Thursday into Friday but stalling just east of SW Montana.
At the same time a wave of monsoonal moisture is rounding the top of a High-pressure ridge and will increase cloud cover over SW Montana Thursday into Friday and could produce a few isolated showers or thunderstorms both Thursday afternoon and Friday afternoon.
Montana will be split with slightly cooler air across the far eastern half of the state vs. hot weather for the far western half of Montana through Friday.
Over the Labor Day weekend most of Montana should be warm to mild (or near normal) and mostly dry. Mountain ranges could see a few isolated rumbles Friday into Saturday.
TRACKING THE TROPICS:
The National Hurricane Center continues to adjust Hurricane Dorian’s track and strenght. The tropical storm increased into a category 1 hurricane as it passes over Puerto Rico.
The update at 3 pm Wednesday from the NHC has this storm lifting over most of the Bahama Islands and if it stays out in open water it will intensify. The storm is on track to hit the central east coast of Florida by Sunday and it could be a strong category 3 hurricane.
