HAZARDOUS WEATHER...
* A CLASSIC SETUP FOR AN ICE STORM WILL BE TAKING SHAPE OVER THE
   NEXT 24 TO 36 HOURS. AN ARCTIC COLD FRONT IS MAKING ITS WAY
   ACROSS THE REGION TODAY AND WILL BE USHERING IN MUCH COLDER AIR

   MORE BANDS OF MODERATE PRECIPITATION FROM SOUTHEAST OKLAHOMA UP
   INTO WEST CENTRAL ARKANSAS BEGINNING THURSDAY AFTERNOON AND
   CONTINUING INTO FRIDAY. THIS JET WILL ALSO MAINTAIN A WARM LAYER
   ALOFT WHICH WILL ALLOW FOR PRECIPITATION TO MAKE IT TO THE
   GROUND AS LIQUID THURSDAY AFTERNOON AND NIGHT OVER THIS REGION
   WHERE SURFACE TEMPERATURES WILL BE BELOW FREEZING. THE RESULT
   WILL BE SIGNIFICANT ICE ACCUMULATION...WHICH WILL LIKELY CAUSE
   MAJOR TRAVEL IMPACTS AND POWER DISRUPTIONS. THE PRECIPITATION
   WILL EVENTUALLY CHANGE OVER TO SLEET AND SNOW BY EARLY FRIDAY
   FROM NORTH TO SOUTH AS THE COLD AIR GETS DEEP ENOUGH BY THIS
   TIME.
