      **Winter Weather Advisory for most of Siouxland from early Thursday morning through 12 AM Friday**

      After a sunshine filled Wednesday, the wintry weather is moving back into Siouxland as we're tracking not 1 round but 2 of snow. The first round is moving in for our Thursday and this one will be coming in 2 pieces. The first wave of energy will be moving through this morning but will be moving out rather quickly. Roads will be slick but the heavier snow looks to arrive later on today. By this evening, more moderate snow will be taking over Siouxland and this is when the bulk of accumulation will fall with amounts likely in the 1-3" range. Moisture begins to exit late tonight with some sunshine taking back by our Friday. High pressure briefly builds in clearing us out but by Saturday a more potent storm looks to move in. It's still a little early to pin down exact amounts but moderate to maybe even heavy snow accumulations will be a possibility. As it looks now, we could have 12-18 hours of precipitation falling throughout the region with the snow ending by early Sunday morning. Continue to stay tuned to us for the latest as we track this winter storm. By the latter half of the weekend, southerly flow is taking back over and high pressure is building in. This will give us an abundance of sunshine Sunday and Monday. By Tuesday though, a few more clouds will be seen out ahead of a system which could bring some wintry mixed precipitation by Wednesday. Temperatures will be above average though throughout next week with highs in the 30s and 40s Sunday into Wednesday.
