Wind Chill Advisory

Wind Chill Advisory: remains in effect from midnight tonight to 8 am Monday.
The combination of gusty winds and cold temperatures will create extremely cold wind chill readings overnight. Wind chill values...will drop to near zero around sunrise on Monday morning. If you must venture outdoors...make sure you wear a hat and gloves.

Wind chill takes into account how wind and cold feel on exposed skin rather than solely the actual temperature. As the wind increases, heat is carried away from the body at an accelerated rate, driving down the body temperature. Animals are also affected by wind chill.

A strong cold front will push across the Deep South tonight, bringing a line of showers and isolated thunderstorms. Temperatures will drop rapidly behind this front. We are scheduled to be at the freezing mark by early Sunday morning. The moisture source seems to be lacking so, just a mention of flurries possible at this time for the Birmingham area. The major concern after the rain will be Black Ice. Rural, valley and low lying areas in particular; Roads which appear clear in the cold season may actually be coated with a thin layer of ice, commonly called black ice. This nearly invisible ice layer can cause you to rapidly lose control of your vehicle. Black ice is most common during the nighttime hours into very early morning. If you detect black ice, reduce your speed!


Behind the front, strong gusty winds will create very cold and blustery conditions. Sustained winds will remain around 20 mph, gusts to 30 or 40 mph. This will create wind chill temperatures in the teens on Sunday...while single digit wind chills are possible in higher elevations. As colder air continues to funnel into the region...temperatures will likely fall into the teens area wide on Monday morning. Continued breezy conditions will produce wind chill temperatures below zero in some portions of the area. A wind chill advisory may be issued for Sunday night and Monday morning.

Winter Weather Coming!


Few isolated showers expected mainly afternoon and in the evening, near Huntsville through Gadsden and Southeast. This front will bring a blast of cold air by Sunday. Tuesday morning thru Wednesday morning look to be the coldest that we have seen so far since last winter, widespread 20s and some teens.
