We are on track to see the first significant winter system of the season in KELOLAND. It looks likely that snow will develop West River Friday night and spread north and east during the day Saturday.
The map above shows an area of low pressure that will develop in northern Colorado moving into the plains on Saturday. Winds will be from the northeast, keeping temperatures cold enough for snow in much of the region. It appears this system will be a fast-mover, so by Saturday night, the low will be located in northern Iowa or southern MN. That fast movement of the storm will limit some of the potential for very heavy snow.
It does appear we will have a few inches of snow with this storm, mainly north of a Valentine, Chamberlain to Marshall line. Sioux Falls could also get clipped by this system with enough snow to get the ground white. We still have time to watch the exact track of the system change a bit, so stay tuned to future forecasts. Right snow, the map below shows the most likely areas to get snowfall.
Did I mention it will be cold? Lows Sunday morning will be in the single digits and wind chills well below zero. Stay warm this weekend!
