Area forecast discussion, Nov 5, 3:30 PM CST, 3 hours 45 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FORT WORTH TX
330 PM CST SUN NOV 5 2000

RADAR INDICATED THE LEADING EDGE OF A SQUALL LINE FROM GAINESVILLE...
TO WEST OF FORT WORTH...TO GLEN ROSE...MOVING NORTHEAST AT 30 MPH.
ADDITIONAL SHOWERS AND THUNDERSTORMS HAVE DEVELOPED BEHIND THIS
SQUALL LINE.  THIS LINE SHOULD PROGRESS ACROSS THE AREA DURING THE
AFTERNOON AND EVENING HOURS...AND BE EAST OF OUR CWA BY DAYBREAK.
WILL GO WITH HIGH POPS TONIGHT ACROSS THE WHOLE REGION...WITH SLIGHT
POPS IN THE WEST AND CENTRAL TOMORROW MORNING...BEFORE CLOUDS
DECREASE.  WILL KEEP PRECIP AROUND A LITTLE LONGER ON MONDAY IN THE
EAST.

MAIN QUESTION IS FLASH FLOOD POTENTIAL.  DUE TO THE FORWARD SPEED OF
INITIAL LINE...THE HEAVY RAIN SHOULD BE BRIEF OVER A GIVEN POINT.
HOWEVER...WITH MORE ACTIVITY DEVELOPING TO THE SOUTHWEST...THERE MAY
BE SOME THREAT OF FLASH FLOODING...ESPECIALLY IN THE SOUTH.  SOME
AREAS OF THE SOUTHERN CWA RECEIVED COPIOUS AMOUNTS OF RAINFALL THIS
PAST WEEK.  ADDITIONALLY...EVEN IF IT RAINS LIGHT TO MODERATE
FOR A PROLONGED PERIOD...THE FLASH FLOOD POTENTIAL EXISTS. ATTM...IT
LOOKS LIKE WE WILL GO WITH A FFA FOR ALL ZONES. WITH THE WET GROUND
IN THE SOUTH...AND BULK OF THE CURRENT ACTIVITY IN THE NORTH...HEAVY
RAIN AND LOCAL FLASH FLOODING IS POSSIBLE JUST ABOUT ANYWHERE.

FWC TEMPS LOOK REASONABLE...AND WILL USE THEM WITH JUST SOME MINOR
ADJUSTMENTS.

IN THE EXTENDED...MOST OF MONDAY WILL BE DRY OVER THE AREA...AND
TUESDAY LOOKS TO BE DRY TOO.  ANOTHER SYSTEM WILL APPROACH THE AREA
ON WEDNESDAY BRINGING THE POTENTIAL FOR MORE SHOWERS AND
THUNDERSTORMS.

DFW 59/71/49/60 +200
