AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LITTLE ROCK AR
345 AM CST WED MAR 29 2000

FOCUS MAINLY ON THE NEAR TERM OR FIRST 24 HOURS OF FORECAST THIS
MORNING. BASICALLY WENT WITH THE MESO-ETA MODEL WHICH SUGGESTS WEAK
FORCING THIS MORNING..BUT ANOTHER SHORT WAVE REACHING THE WESTERN
BORDER OF ARKANSAS AROUND 21Z THIS AFTERNOON PROVIDING A FOCUS FOR
BETTER COVERAGE OF CONVECTION. IT APPEARS THAT NEARLY STATIONARY
FRONT JUST NORTH OF SOUTHERN BORDER LAST EVENING..HAS SAGGED A
LITTLE FURTHER SOUTHWARD. MESO-ETA ALSO SUGGESTS SOME SURFACE
RIDGING INTO CENTRAL ARKANSAS TODAY. STILL SUSPECT NORTHEAST FLOW
WILL PREVAIL TODAY OVER MANY AREAS..AND THUS FRH TEMPS A LITTLE TOO
WARM.
