Special Weather Statement
Now - Tuesday, Nov 26, 3:15pm
...WINTRY PRECIPITATION EXPECTED TONIGHT ACROSS THE TENNESSEE VALLEY...
PERIODS OF RAIN WILL OCCUR TODAY AS A STRENGTHENING AREA OF LOW PRESSURE TRACKS FROM THE GULF COAST TO CENTRAL GEORGIA. AS COLDER AIR GETS PULLED IN BEHIND THE SYSTEM...RAIN WILL BRIEFLY MIX WITH SLEET AND SNOW BEFORE CHANGING TO ALL SNOW THIS EVENING. EXPECT THIS CHANGEOVER TO OCCUR BETWEEN 6 AND 9 PM THIS EVENING FOR AREAS WEST OF I-65...AND BETWEEN 9 PM AND MIDNIGHT FOR AREAS EAST OF I-65. THE DURATION OF SNOWFALL WILL BE RELATIVELY SHORT...HOWEVER A QUICK DUSTING TO UP TO AN INCH OF SNOW ACCUMULATION IS POSSIBLE BEFORE THE SNOW TAPERS OFF WEST TO EAST AFTER MIDNIGHT. THE HIGHER ELEVATIONS OF NORTHEAST ALABAMA AND SOUTHERN MIDDLE TENNESSEE...SUCH AS THE CUMBERLAND PLATEAU ALONG WITH SAND AND LOOKOUT MOUNTAINS...COULD SEE LOCALLY HIGHER SNOW ACCUMULATIONS.
DUE TO RELATIVELY WARM GROUND TEMPERATURES...ANY SNOW OR SLEET THAT INITIALLY FALLS SHOULD MELT ON THE ROADS. HOWEVER...AS TEMPERATURES DROP TO NEAR OR SLIGHTLY BELOW FREEZING THROUGH THE NIGHT...SOME ICY AND SLICK SPOTS WILL DEVELOP...ESPECIALLY BRIDGES...OVERPASSES AND LESS TRAVELED SECONDARY ROADS. EVEN AFTER THE PRECIPITATION ENDS...RESIDUAL MOISTURE ON ROADS COULD RESULT IN THE FORMATION OF BLACK ICE THAT COULD LINGER THROUGH WEDNESDAY MORNING. TEMPERATURES ARE ONLY EXPECTED TO WARM TO THE LOWER TO MID 30S ON WEDNESDAY.
THOUGH THIS IS NOT EXPECTED TO BE A MAJOR WINTER WEATHER EVENT FOR NORTH ALABAMA AND SOUTHERN MIDDLE TENNESSEE AT THIS TIME...MOTORISTS ARE URGED TO USE EXTREME CAUTION IF YOU MUST TRAVEL TONIGHT INTO EARLY WEDNESDAY MORNING.
