A combination of freezing rain, sleet, and snow will affect all areas at some point Sunday into Monday. Significant ice accumulations are possible.
A wintry mix of precipitation will spread north into the area Sunday evening and continue into Monday. Precipitation is expected to begin as either freezing rain or sleet Sunday evening, becoming all freezing rain in the area early on Monday.
Ice accumulations of a quarter inch or more are possible. Hazardous or impossible travel due to icy or snow-packed roads is likely. Sidewalks and parking lots will be very slippery as well. Some damage to tree limbs and power outages are possible.
An ice storm warning means severe winter weather conditions are expected or occurring. Significant amounts of ice accumulations will make travel dangerous or impossible. Travel is strongly discouraged. Commerce will likely be severely impacted. If you must travel, keep an extra flashlight, food, and water in your vehicle in case of an emergency. Ice accumulations and winds will likely lead to snapped power lines and falling tree branches that add to the danger.
A winter weather advisory has also been issued. Ice accumulations in the advisory will be around a tenth of an inch to as much as a quarter of an inch, with snowfall totals of an inch to possibly two inches in some spots.
Winds will be light out of the east at 5 to 10-mph. Roads and sidewalks may become ice coated and very hazardous.
