BE MUCH HIGHER SOUTH OF AR WITH THIS SYSTEM.

A COLD FRONT WILL PUSH SOUTH THROUGH THE STATE LATE WED NIGHT AND
THU...WITH COLDER TEMPS RETURNING. THERE MAY BE ENOUGH ENERGY AND
MOISTURE WITH A WEAK UPPER WAVE ASSOCIATED WITH THIS FRONT TO
GENERATE SOME PRECIP THU INTO THU NIGHT. HOWEVER...HAVE ONLY
MENTIONED SLIGHT CHANCE POPS AT THIS TIME AS MODEL TO MODEL
CONSISTENCY IS NOT THE BEST THIS FAR OUT. IF ENOUGH MOISTURE AND
LIFT WERE TO DEVELOP...SOME RAIN...POSSIBLY MIXING WITH SOME WINTRY

AS ANY PRECIP WILL BE LIGHT...AND CERTAINTY REMAINS LOW AT THIS TIME.
