The first major snow storm of the season will bring heavy snow and strong winds to eastern Nebraska, western Iowa and northwest Missouri on Sunday morning.
Blizzard warnings have been posted for areas south of the Omaha metro, while a Winter Weather Advisory continues for the metro area through Sunday afternoon. Snow will begin after midnight, and combine with strong winds to produce near white-out conditions at times Sunday morning.
Rain is expected to begin developing over the area after dark. Initially rain showers will be north of the metro, but should push into town after 7pm according to WOWT. Rain will then change over to snow after midnight from north to south.
Expect that transition to snow in the metro by 3 a.m. A couple hours of heavy snow is possible through about 6 or 7 am before snow will begin to let up. However, as the snow moves in, winds will pick up significantly.
Gusts of 30 to 40vmph are expected by Sunday morning. This will cause considerable blowing and drifting of snow across the area, and will make travel difficult during the morning hours. Even areas that see lighter snow amounts will still likely see significant impacts from blowing snow.
White out conditions are possible at times in the metro area, with sustained blizzard conditions possible south of the metro at times Sunday morning. Snow should wind down by noon on Sunday, but blowing and drifting snow may continue to be a problem through the day as gusty winds stick around.
Winds will eventually die down in the evening, and skies may even clear out overnight. Cold and clear conditions will move in by Monday morning, with lows falling into the teens.
In anticipation of the storm OPS has already canceled all activities for Sunday.
