A Winter Storm Warning is in effect for the Snowy and Sierra Madre Ranges tonight through early Sunday morning. A prolonged snow event will lead to 1 to 2 feet of snowfall accumulation in the mountains. Strong winds are also expected which will lead to blowing snow and reduced visibility.
Another high wind warning has been issued, this time just for our usual wind prone locations of Arlington and Bordeaux, valid during the early morning hours on Sunday through the beginning of the afternoon.
6AM 12/6 - Windy conditions and areas of snow showers will continue to produce hazardous travel conditions in the wind prone areas of southeast Wyoming. Look for widespread gusty winds both today and tomorrow with near average temperatures. Snow shower activity is expected to clear out by Sunday afternoon with more sunshine on track then too.
6AM 12/6 - The overall forecast for the week ahead can be described with one word: wind. Today through Monday, expect near average temperatures with strong winds in the southeast Wyoming wind prone areas and breezy to windy conditions elsewhere. Travel may be hazardous for light-weight and high profile vehicles nearly every day for the next week. We are watching the potential for a significant wind event possible in the Tuesday through Thursday time period. There is high confidence in strong winds beginning around Monday night or Tuesday, but uncertainty in how long this wind event will last. There are two possible scenarios for the middle to later part of the week ahead: In one scenario, the arctic cold front remains just to our northeast, and we remain warm and largely dry with strong winds continuing through Thursday. In the other scenario, an arctic cold front sneaks in from the north and shuts off the wind on Wednesday or Thursday, but brings colder temperatures and a chance for snow. We will have more updates on the potential wind event in the coming days. The graphic attached is intended to give an idea on what kind of wind is possible this week, but since we are still a few days out, the exact timing and wind speeds are likely to change.
