FLASH FLOOD WARNING
NATIONAL WEATHER SERVICE MIDLAND TX
957 PM CDT SUN AUG 25 1996

THE NATIONAL WEATHER SERVICE IN MIDLAND TX HAS ISSUED A
FLASH FLOOD WARNING EFFECTIVE UNTIL 155 AM CDT
FOR PEOPLE IN THE FOLLOWING LOCATION...

IN WEST TEXAS

   ...PRESIDIO COUNTY
 
AT 950 PM CDT THE SHERIFFS DEPARTMENT REPORTED STREET FLOODING IN
PRESIDIO TEXAS.  SINCE RAIN CONTINUES TO FALL OVER THE PRESIDIO
AREA...THE RUNOFF COULD CAUSE ADDITIONAL FLOODING OVER THE NEXT FEW
HOURS.

ELSEWHERE IN THE COUNTY...RAIN...HEAVY AT TIMES...CONTINUES TO FALL
OVER THE MARFA PLATEAU.  DUE TO PREVIOUS HEAVY RAINS THE ADDITIONAL
RUNOFF FROM THESE RAINS WILL LIKELY PRODUCE FLOODING.

SATELLITE IMAGERY SHOWS ABUNDANT MOISTURE OVER THE COUNTY WITH
CONTINUING RAINFALL.  THEREFORE...FLOODING WILL LIKELY CONTINUE OVER
THE AREA.

BE ESPECIALLY CAUTIOUS AT NIGHT WHEN IT IS HARDER TO RECOGNIZE THE
DANGERS OF FjLOODS AND FLASH FLOODS. IF FLOODING IS OBSERVED...ACT
QUICKLY. MOVE UP TO ESCAPE FLOOD WATERS. DO NOT STAY IN AREAS
SUBJECT TO FLOODING WHEN WATER BEGINS RISING.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIDLAND TX
905 PM CDT SUN AUG 25 1996

ANALYSIS OF LATEST WV LOOP INDICATES A SHIFT IN THE MOISTURE AXIS
COMPARED TO THIS TIME YESTERDAY. MAJORITY OF MOISTURE NOW
PUSHING OVER CWA FROM THE PRESIDIO AREA. ALTHOUGH AIRMASS OVER CWA
IS CLEARLY TROPICAL...ENOUGH BREAKS TODAY CAUSED A TRANSITION FROM A
STRATIFORM PRECIPITATION EVENT TO A CONVECTIVE EVENT. HOWEVER WITH
LOWER LAYERS STILL SATURATED...HOLES WILL CLOSE IN ONCE AGAIN
TONIGHT WITH DIURNAL COOLING.

AS FOR MODELS...DID GLANCE AT THE ETA. APPEARS LOW-LEVEL MOISTURE
(SURFACE THROUGH 700 MB) WILL HANG IN THROUGH 48 HOURS.
HOWEVER...ETA DOES INDICATE DRYING MOVING IN FROM THE NORTHWEST IN
THE 24-48 HOUR PERIOD. THIS APPEARS RESONABLE BASED ON CURRENT WV
LOOP INDICATING A DRY SLOT OVER SOUTHERN AZ. WITH WHITE SANDS
PROFILER CLEARLY INDICATING WESTERLIES ABOVE 500 MB...UPPER-LEVEL
DRYING POSSIBLE.

LOOKING AT KMAF WSR-88D...COVERAGE IN THE SOUTHWEST APPEARS TO BE ON
THE INCREASE. AFTER COORDINATION WITH THE LBB TEAM...HAVE DECIDE TO
UP POPS FOR THAT PORTION OF CWA. OTHERWISE...NO OTHER CHANGES.

AS USUAL...RECEIVED OUTSTANDING SUPPORT...GUIDANCE...AND INPUT FROM
LBB TEAM!
