THIS WINTER PRECIPITATION WAS DUE TO A VERY COLD UPPER LEVEL LOW
PRESSURE SYSTEM MOVING OVERHEAD. THE LATEST WATER VAPOR IMAGERY
HAS A JET STREAK MOVING NORTHWARD AHEAD OF THIS FEATURE…WHICH
SHOULD ALLOW IT TO KICK OUT TO THE NORTH AND EAST THIS
EVENING….BUT MAY HELP INTENSIFY SOME OF THE PRECIPITATION OVER
THE NEXT FEW HOURS. THE AREAS THAT HAVE SURFACE TEMPS BELOW
FREEZING WILL EXPERIENCE THE MOST ROADWAY IMPACTS. IF YOU DO NOT
HAVE TO TRAVEL OVER THE NEXT FEW HOURS…PLEASE STAY OFF THE
ROADWAYS ACROSS NORTH CENTRAL ALABAMA.
