Flash Flood Warning 18, NWS Houston/Galveston, TX

SOUTHEAST TEXAS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX
958 AM CDT THU JUN 7 2001

AT THIS TIME THE CENTER OF CIRCULATION OF THE REMNANTS OF TROPICAL
DEPRESSION ALLISON WERE LOCATED OVER HOUSTON COUNTY AT THE SURFACE AND
MID LEVELS.  THE IR AND WATER VAPOR INDICATED THERE WAS LESS DRY AIR
ENTRAINED IN THE SYSTEM THAN EIGHT HOURS AGO...HOWEVER THE DRY SIDE OF
THE STORM WAS OVER THE SOUTHWESTERN COUNTIES.  FORECAST PROBLEM OF THE
DAY CONTINUES TO BE THE AMOUNT AND EXTENT OF RAINFALL.

RAINBANDS CURRENTLY AROUND THE LOW WERE BEGINNING TO MOVE IN A
SOUTHEASTERLY DIRECTION AS OPPOSED TO TRAINING IN A WEST TO EAST
MANNER FROM EARLIER THIS MORNING.  AM STILL CONCERNED THAT NEW BANDS
WILL FORM TO THE SOUTH OF THE MAIN AREA OF RAIN AROUND THE LOW AND
THAT THESE WILL TRAIN OVER COUNTIES IN THE CURRENT FLASH FLOOD WATCH
AREA.  ALTHOUGH AM STILL NOT VERY CONFIDENT WITH THE SPECIFICS OF THE
MODEL DATA...THE ETA CONTINUES TO SOUTHWARD TREND OF THE LOW...MOVING
IT PAST THE CLL AREA THIS AFTERNOON.  THIS SCENARIO SHOULD KEEP THE
EASTERN TWO THIRDS OF THE FORECAST AREA IN A CATEGORICAL POP
SITUATION.  THE DRY AIR ENTRAINING INTO THE SYSTEM JUST OFF THE TX
COAST MAY CAUSE A FEW STRONG STORMS OVER COASTAL COUNTIES...BUT THE
SEVERE THREAT IS ISOLATED AT BEST.

WILL CONTINUE THE FLASH FLOOD WATCH AND UPDATE THE FORECAST TO TAKE
OUT THE MORNING REFERENCES.  WILL ALSO CHANGE THE COASTAL ADVISORIES
SO THAT THE SCA IS OVER THE NORTHERN MARINE ZONES AND SCEC OVER THE
SOUTHERN ZONES.
