AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIDLAND TX
1004 AM CDT (904 AM MDT) SAT JUN 12 1999

TOUGH FORECAST TODAY AS FAR AS TEMPERATURES. IF CLOUDS PERSIST ALL DAY
THEN GOING FORECAST TEMPERATURES WILL BE TOO HIGH...HOWEVER CURRENT
THINKING IS THAT CLOUD COVER WILL BURN OFF BY AFTERNOON AND WILL HAVE NO
TROUBLE REACHING THE EXPECTED HIGH TEMPERATURES. CURRENT ZONE FORECAST
IS IN PRETTY GOOD SHAPE...HOWEVER WILL TWEAK THE GUADALUPE MOUNTAIN ZONE
TO ACCOUNT FOR ALL THE MORNING CLOUDS IN THAT AREA. WILL CONTINUE WITH
FFA AS MANY AREAS ACROSS THE CWA WILL FLOOD QUICKLY WITH ANY ADDITIONAL
RAINFALL. WILL CONTINUE THE FFW FOR SCURRY COUNTY UNTIL NOON THEN WILL
CHANGE IT TO A FLOOD WARNING AS THIS SEEMS TO BE THE HARDEST HIT FLOOD
AREA. WE ARE STILL MONITORING DEEP CREEK AS IT CONTINUES TO SHOW
SIGNIFICANT RISES.

FOR SE NM ZONES...WILL UP THE POPS A LITTLE OVER THAT AREA.

WORK SET OF ZONES ON THE WAY SHORTLY.
