AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LITTLE ROCK AR
855 PM CST MON DEC 22 2003

SEVERE WEATHER STARTING TO CRANK UP SO DISCUSSION WILL BE BRIEF
TONIGHT. SEVERE THUNDERSTORM WATCH NUMBER ONE HAS EXPIRED OVER THE

LATEST SURFACE ANALYSIS PLACES SURFACE LOW PRESSURE OVER OVER
NORTHWEST ARKANSAS WITH ASSOCIATED COLD FRONT ALONG THE ARKANSAS AND
OKLAHOMA BORDER.

SHOWERS AND THUNDERSTORMS STILL EXPECTED TO SWEEP ACROSS THE STATE
OVERNIGHT SO CURRENT FORECAST LOOKS REASONABLE. THREAT OF SEVERE
WEATHER WILL WANE WITH TIME AS STORMS SHOULD BECOME MORE ELEVATED
WITH TIME AND RUN INTO A MUCH LESS FAVORABLE ENVIRONMENT. BEST
