FLASH FLOOD WARNING
NATIONAL WEATHER SERVICE MIDLAND TX
247 AM CDT THU AUG 7 1997

THE NATIONAL WEATHER SERVICE IN MIDLAND TX HAS ISSUED A
FLASH FLOOD WARNING EFFECTIVE UNTIL 700 AM CDT
FOR PEOPLE IN THE FOLLOWING LOCATION...

IN WESTERN TEXAS

   ...TERRELL COUNTY
 
AT 239 AM CDT... MIDLAND DOPPLER RADAR HAD ESTIMATED BETWEEN ONE AND
TWO INCHES OF RAIN HAD FALLEN OVER NORTHERN TERRELL COUNTY OVER THE
PAST TWO HOURS.  THE THUNDERSTORMS CAUSING THE HEAVY RAINFALL WILL
CONTINUE TO TRAIN ALONG AN OUTFLOW BOUNDARY OVER THE NORTHERN
PORTION OF THE COUNTY.  THIS OUTFLOW BOUNDARY WILL PUSH SLOWLY SOUTH
OVER THE NEXT SEVERAL HOURS AND CARRY THE HEAVY RAINFALL INTO THE
SOUTHERN PORTIONS OF THE COUNTY.  DUE TO THE SLOW MOVEMENT OF THIS
OUTFLOW BOUNDARY AND THE SLOW EASTERLY MOVEMENT OF THE STORMS... AN
ADDITIONAL ONE TO TWO INCHES OF RAIN CAN BE EXPECTED OVER NORTHERN
TERRELL COUNTY WITH RAINFALL TOTALS NEAR SANDERSON REACHING ONE TO
TWO INCHES BY 4 AM.

PEOPLE DRIVING ALONG HIGHWAY 349 ABOUT 9 MILES SOUTHWEST OF
SHEFFIELD SHOULD WATCH FOR WATER COVERING THE ROADWAY.

BE ESPECIALLY CAUTIOUS AT NIGHT WHEN IT IS HARDER TO RECOGNIZEd THE
DANGERS OF FLOODS 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...CORRECTED P07 POPS
NATIONAL WEATHER SERVICE MIDLAND TX
155 AM CDT THU AUG 7 1997

06Z SURFACE ANALYSIS AND 88D SHOWS STRONG COLD FRONT... AT LEAST FOR
THIS TIME OF YEAR... OVER NORTHERN BREWSTER... SOUTHERN PECOS AND
NORTHERN TERRELL COUNTIES.  GREATEST PRESSURE GRADIENT REMAINS OVER
THE PANHANDLE AND SOUTH PLAINS ATTM.  HEAVIEST RAINFALL OCCURRING
NEAR FRONTAL BOUNDARY ATTM WITH WEAKER AREA OVER NORTHERN PERMIAN
BASIN WEAKENING WITH TIME.  WV IMAGERY SHOWING NICE TROPICAL
CONNECTION OVER PORTIONS OF THE CWA.  LOW CLOUDS HAVE MADE IT TO
MIDLAND AS THEY CONTINUE SOUTHWARD.

MODELS IN GOOD AGREEMENT WITH RAINY WEATHER PATTERN OVER THE FA
NEXT 36 TO 48 HOURS AS S/W TROUGH HANGS OUT OVER THE TX PANHANDLE
NEXT 24 HOURS BEFORE SLOWLY MOVING OVER N TX BY 48 HOURS.  A SERIES
OF WEAK DISTURBANCES WILL MOVE THROUGH THE AREA AS WELL.  THIS
COMBINED WITH THE RIGHT EXIT REGION OF THE H25 JET OVER OUR
NORTHERN PORTIONS WILL PROVIDE ENOUGH UPWARD MOTION OVER THE FA TO
KEEP A GOOD CHANCE OF PRECIPITATION OVER MUCH OF THE REGION.
HOWEVER... WITH FRONT HAVING MOVED AS FAR SOUTH AS IT HAS EXPECT
MAINLY STRATOFORM PRECIPITATION OVER THE NORTHERN PORTIONS.  APPEARS
THERE MAY BE ANOTHER MAXIMA TOMORROW AS AN AREA OF GOOD QVEC CONV
CAN BE SEEN IN THE LAYER FROM H85 TO H3 ACCORDING TO ETA WITH NGM A
LITTLE SLOWER AND FRONT BEGINS TO MOVE BACK NORTH.  GIVEN EXPECTED
SLOW MOVEMENT OF THUNDERSTORMS... ABUNDANT MOISTURE (PW GREATER THAN
1.25 INCH)... AND TROPICAL CONNECTION BELIEVE A FFA MAY NEED TO BE
CONSIDERED LATER TODAY IN VICINITY OF AFOREMENTIONED FRONT...
ESPECIALLY IF IT STALLS.

TEMPERATURES REALLY GOING TO BE TOUGH THIS TIME AROUND AS CLOUD
COVER... SHRA/TSRA... AND QUASI/STATIONARY FRONT WILL ALL PLAY A
DIFFICULT ROLE.  ATTM WILL LEANING ON THE COOL SIDE OF NGM FOR HIGHS
AS AVN STILL APPEARS TO BE ON THE COOL SIDE... ESPECIALLY GIVEN ITS
14 DEGREE TEMPERATURE DEPARTURE YESTERDAY.  AS FOR LODWS... WILL KEEP
WITH PERSISTENCE WITH A TOUCH OF GUIDANCE AS CLOUD COVER SHOULD KEEP
DIURNAL VARIATION WITHIN 10 TO 15 DEGREES.
