A HIGH WIND WARNING remains in effect for the Rocky Mountain Front, Toole, Cascade and Judith Basin Counties.
A WINTER WEATHER ADVISORY for blowing snow remains in effect for Fergus County.

Another wind event is blowing through the state, fortunately it will not be as bad as last week's widespread damage. Nonetheless, a power outage, some tree and property damage, as well as difficult travel remain possible through the warning area. After the weekend snow, blowing snow could affect areas in Fergus County. Wind gusts have already topped 60mph along the Rocky Mountain Front. A peak gust of 96mph occurred just south of East Glacier. Wind will remain strong through the night and Wednesday morning. While the wind will persist through the day, wind speeds will ease up through late morning and the afternoon. By Thursday morning, wind will be much lighter across the state. Besides the wind, Wednesday will be mostly sunny with highs in the 30s and 40s. Thursday, a weak area of low pressure will move toward southwest Montana spreading a little light snow there. The snow should make it up through Helena, but not quite to Great Falls. South of a line from Missoula to Great Falls to Lewistown will have the best chance of light snow that could accumulate 1-3" in the lower elevations. Highs will be colder in the 20s and 30s. Some light snow will continue through Thursday night into Friday mainly for the southern half of the state. While accumulations will be light, there will be enough snow to make for slippery roads. Highs on Friday will remain in the 20s to low 30s. Northern Montana will have a little sunshine both on Thursday and Friday. This weekend will be quiet with partly cloudy skies on both Saturday and Sunday. Highs will be in the 20s and 30s, and the wind will be fairly light. Snow is possible again late Monday night into Tuesday. Right now, the real arctic air with subzero temperatures should remain just to the north of Montana. It is likely that some areas over the weekend will have low temperatures dropping below zero.
Have a great day.
