Cold air has settled back into the region and will stick around through the middle of the week, setting the stage for what could be a messy day for some on Thursday. We're tracking a storm system that is moving down the California coastline and will lead to a winter storm for the middle of the country today and tomorrow. As we often see around here, different types of wintry weather could be possible in different locations across the Local 6 region, depending on how temperatures play out both at the surface and higher in the atmosphere through the course of the day.
A mix of light snow, sleet, and freezing rain will be possible Thursday morning, especially in SE Missouri, which could lead to some slippery travel conditions. Small snow and ice accumulations will be possible, especially in Southern IL, Southeast MO, and closer to the Ohio & Mississippi Rivers in Western KY.
As we go into Thursday afternoon and evening, warmer air will begin to push in from the south, and should result in a changeover to just cold rain for most of the area, melting anything that accumulates during the morning.
Computer models have not been in good agreement with this system because of a lack of weather observation stations out in the Pacific Ocean, leading to a limited amount of data to use to analyze this system. Now that this storm is onshore, computer models will have more data to look at, and the forecast should become clearer moving forward. Stay tuned to Local 6 for updates to the forecast as new information comes in.
