Special Weather statement – 12-12-18
Issued by the National Weather Service
In effect until 8am cst Wednesday. Wintry precipitation likely to cause slippery roads this morning. Untreated roads and sidewalks are likely to become slippery this morning as a combination of light snow and freezing drizzle develops across the area.
Only up to an inch of snow is expected, but when combined with the freezing drizzle it will be sufficient to result in hazardous travel conditions across portions of the area.
At 430 am, precipitation was beginning to develop in central and western Wisconsin. The development of the precipitation has thus far been slowed by dry air in the middle levels of the atmosphere. But the precipitation will become more widespread by mid-morning as a strong upper level disturbance approaches from the West.
The precipitation is expected to fall as a combination of light snow and drizzle, with the drizzle freezing on contact with the surface where temperatures are below freezing. Central Wisconsin and the western portion of the fox valley will be most susceptible to having freezing drizzle produce a thin layer of ice on roads and sidewalks, and so a winter weather advisory has been posted for those areas.
Farther north, the precipitation will be lighter and fall as primarily snow. Locations in east-central Wisconsin will have temperatures hover near freezing, so the potential for roads to become icy will be lower. Morning commuters, especially those in central and portions of east-central wisconsin away from lake michigan, should be prepared to encounter icy spots on the roads. Use extra caution, and allow for some extra travel time this morning.
