A WINTER STORM WARNING continues for parts of central and eastern Montana through Thursday.
A WINTER WEATHER ADVISORY has been issued for parts of central and north-central Montana including Helena and Great Falls.

The first wave of snow has come and gone, dropping up to a foot in some areas. Another round of accumulating snow will move into the state for Thursday. This next round of snow will be from the main area of low pressure. Although this is the storm center and the snow will be widespread, it will be a little lighter this time accumulating a few inches. Snow will increase through Wednesday night into Thursday. Snow will be light to moderate and the morning commute will be a mess again. Highs will only top out in the 10s and 20s. The storm system will pull away Thursday night, and lows will fall to near record levels in the -0s and 0s. Friday will be partly to mostly cloudy with a few light flurries or snow showers, but any additional accumulation will be light. Storm totals when all is said and done will be up to 12-24" for some areas! Friday will be cold with highs in the 10s and 20s and lows that night will again fall to near record lows in the -0s and 0s. While the storm moves away for the weekend, we're not out of the woods yet. Wind woes will come later in the weekend. Saturday will be partly to mostly sunny with light wind in the valleys, but a 10-20mph wind will blow snow along the Rocky Mountain Front out across the north-central part of the state including Great Falls. Highs will still be well below average in the 20s. Sunday will be mostly sunny and cold with highs in the 20s to around 30. Wind will be calm in the valleys but continue to gust up along the Rocky Mountain Front and out across north-central Montana. Blowing snow will likely be an issue as wind increases to 30-35mph again in places like Great Falls. Monday will be partly to mostly cloudy with slightly warmer temperatures in the 30s. The wind will be light or calm in the valleys like Helena, but blowing snow will be a problem up on the Continental Divide, off the Rocky Mountain Front and out across central Montana. Halloween is Tuesday and warmer temperatures will move in. Highs should reach the 40s for most. While it won't be bitter cold, the warmer temperatures should make for some sloppy and slushy trick or treating.

Have a great day,
