THE THREAT WILL PRIMARILY BECOME STRAIGHT LINE WINDS.
UNFORTUNATELY...THE SYSTEM HAS A LARGE AMOUNT OF WIND ENERGY WITH
IT...AND TORNADO DEVELOPMENT CANNOT BE RULED OUT. THE GREATEST
THREAT FOR ANY TORNADO DEVELOPMENT WILL BE IN AREAS WEST OF A LINE
FROM WALDRON...TO MALVERN...TO MONTICELLO. THE FRONT WILL ENTER

BE COMMON ACROSS THE AREA. FOR THIS REASON...A LAKE WIND ADVISORY

OF INTERSTATE 30.
STRONGER STORMS WILL ALSO BE CAPABLE OF PRODUCING LOCALLY HEAVY
RAINFALL...WITH PORTIONS OF ARKANSAS RECEIVING AN ADDITIONAL INCH OR
MORE ON THURSDAY. THIS WILL INCREASE THE POSSIBILITY OF FLASH

STATE. AS THE COLDER AIR MIXES IN...SOME SNOW WILL BE POSSIBLE
THURSDAY NIGHT THROUGH EARLY CHRISTMAS DAY ACROSS THE NORTH.
SNOWFALL AMOUNTS DO NOT APPEAR TO BE SIGNIFICANT AT THIS TIME...BUT
