Dense fog and freezing rain will impact your morning commute if traveling through north-central Montana. Tiny supercooled liquid water droplets in fog can instantly freeze on road surfaces, especially when the temperatures are near or below freezing. Black ice has been reported in portions of central Montana. The National Weather Service has now issued Dense Fog Advisory and a Winter Weather Advisory. As the day continues, the clouds will increase, and another round of light snow will fall. The mountains could get between 2-5", the mountain passes 2-3," and the lower elevation could get up to 1." There is a high potential for snow bands to develop overnight, and that could lead to an isolated higher amount for the valleys in western Montana. The highs will cool to the 20s and 30s.
Snow showers will continue into early Saturday morning, and by 9 am, we will get a break. The clouds will break apart, and we will see a little more sunshine. Tomorrow daytime high will again trend in the 20s and 30s.
Sunday, another batch of moisture will move in, bringing a wintry mix to the mountains and possible rain showers to the lower elevations. The wind will pick up, mostly cloudy skies will return, and the highs will stay in the 20 and 30s.
Have a great weekend.
