A Winter Weather Advisory for snow and blowing snow means that periods of snow with blowing snow will cause primarily travel difficulties. Be prepared for snow covered roads and limited visibilities, and use extra caution while driving.

Forecast snowy weather has prompted the Shelby County Emergency Management Agency to reduced the field/grassland Fire Danger category to “Low,” from now through Monday, when the next update will be available. Earlier this week, dry and windy conditions, as well as numerous recent grass and brush fires in Shelby County, had resulted in the Fire Danger being elevated to High.
