**Dense Fog Advisory for viewing area through mid-morning**
**Winter Weather Advisory for northeast Kansas from lunch hour to early Thursday morning**
Fog has gradually become more prevalent each morning this week. Snow produces more moisture near the ground, plus it makes the air near the ground colder than the air just above it. Those conditions can make for poor visibility on a widespread basis.
A Dense Fog Advisory is in effect again for the entire region. Clouds will likely be stubborn so any sunshine is highly unlikely. A weak disturbance could generate freezing drizzle, light freezing rain and sleet for most locations later today and this evening. All precipitation should be light, but it won’t take much to create slick spots. Everything likely goes east at daybreak, but it could leave behind some ice for early morning travel on Thursday.
Greater Topeka Wednesday…
Wind: NE 5-15
Thursday may stay variably cloudy to mainly cloudy and chilly. Then, the next snow into the weekend will have much colder air at work. It may start as rain to ice, but when it goes to snow it should be like feathers with air pockets. This creates a snow that is easier to remove, but it can lead to blowing and drifting problems if the wind is high.
Snow might be potentially wet and slushy into Friday evening, but accumulations likely double the previous system’s numbers through Friday night and Saturday with much colder air surging in. We will need to monitor not just totals, but also determine how much blowing and drifting could occur for the travel impact. Wind on Saturday may stay between 20-40mph which would produce whiteout conditions.
You may need to alter travel plans for late Friday through Saturday, which certainly means leaving earlier and/or staying longer. You may want to be at your location west of here by midday Friday and avoid travel east after 7-9pm Friday night. This event may require a Winter Storm Warning, and potentially a Heavy Snow Warning or Blizzard Warning for Saturday across our viewing area.
