AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
1110 AM CDT SUN MAY 27 2001

MADE QUICK UPDATE TO ZONES TO REMOVE "EARLY" WORDING AND LOWER POPS
IN CENTRAL ZONE GROUPS. AN ILL-DEFINED SURFACE WARM FRONT EXTENDING
FROM NE TX TO CNTRL MS CONTINUES TO DRIFT SLOWLY NORTH. BELIEVE THAT
A FEW OUTFLOW/DIFFERENTIAL HEATING BOUDARIES EXIST AS WELL. WITH THE
AIRMASS MOIST AND UNSTABLE (CAPES 1500 TO 3000 J/KG AND PRECIP WATER
~1.4) CONVECTION COULD FIRE ALONG ANY OF THESE BOUNDARIES AND HAVE
LEFT HIGH CHANCE POPS. THE SEVERE THREAT IS LOW FOR THIS AFTN...BUT
NOT LOW ENOUGH TO REMOVE MENTION OF SEVERE IN ZONES. NO OTHER
CHANGES PLANNED ATTM.
