A winter weather advisory will be in effect until 6pm this evening. The heaviest snow will reach western Iowa by 8am, and end over north central Iowa during the afternoon. Snowfall accumulations will be 2 to 3 inches. Winds will be light by visibility will drop rapidly to a mile or less in the heavier snow.
Travel conditions will deteriorate rapidly as the snow moves in, with visibility dropping rapidly from west to east between mid morning and around midday. Roads will also become snow covered and slick. Please reconsider or adjust your travel plans accordingly.
A winter weather advisory for snow means that periods of snow will cause primarily travel difficulties. Be prepared for snow covered roads and limited visibilities, and use caution while driving.
