The first significant wintry weather of the season will be across much of Siouxland Tuesday and Tuesday night. In fact, a Winter Weather Advisory is in effect for northwestern Siouxland for Tuesday including Holt, Knox, Cedar, Antelope, and Pierce counties in Nebraska; Lincoln, Clay, and Yankton counties in South Dakota; and Lyon and Osceola counties in Iowa.
It is these counties that could see the heaviest snowfall of accumulation with about 3 to 5 inches expected. Some locations could inch upward toward 6 inches or a bit more but that should be more isolated than widespread. This may start as a rain and snow combination Tuesday morning before becoming all snow by the afternoon.
We’ll have a chance of some snow here in Sioux City but it won’t be as much and it will be later in the day. In fact, most of central, southern, and eastern Siouxland should see rain for most of the day before transitioning over to snow toward the later afternoon and evening hours. Some snow could continue into Tuesday night potentially giving Sioux City an inch or two.
This system should move out by Wednesday leaving us with chilly conditions. Just beware of some tough travel conditions in the area. And with this being our first real snow of the season, everyone will be adjusting to driving in conditions that we’re simply not used to. Be careful out there.
