I-15 in Conrad has been CLOSED into Tuesday afternoon after a semi rollover. The Pondera County Department of Emergency Services says only emergency vehicles are allowed.

A HIGH WIND WATCH has been issued for most of Montana for Tuesday.

A wicked wind gusting between 50-70mph will continue to be a problem. After a little let-up in the wind through Tuesday morning, another storm will create even stronger wind through Tuesday afternoon and evening. Some gusts could top 80mph. Power outages are possible. Damage to trees and buildings is possible. Travel with a trailer or in a high profile vehicle will be extremely difficult and is not advised. This approaching storm will also produce mountain snow, rain and thunderstorms will move across the lower elevations. Travel over mountain passes should be slippery Tuesday morning before snow levels rise. The snow levels will drop Tuesday night as a cold front passes through. Wednesday will be another windy day, but with cooler temperatures there will be a mix of rain and snow showers in the lower elevations. The mountains will pick up several inches of snow, with the peaks seeing accumulation over 12". A little coating of snow up to an inch or so is possible in the lower elevations. Thursday will be partly cloudy with a few lingering mixed rain and snow showers. Friday will be windy and warmer ahead of a new weekend storm. A sharp cold front will bring falling temperatures and the likelihood of snow on Saturday. Snow could accumulate a few inches in the lower elevations. Temperatures Saturday night will be the coldest of the season so far. Another disturbance could bring a mix of precipitation on Sunday into Monday.
Have a great day and don't get blown away.
