HAZARDOUS WEATHER OUTLOOK
Issue Date: 110 PM CDT SAT OCT 11 2008
Expiration: 115 PM CDT SUN OCT 12 2008

THIS HAZARDOUS WEATHER OUTLOOK IS FOR THE EXTREME SOUTHERN TEXAS
PANHANDLE...SOUTH PLAINS AND ROLLING PLAINS.

.DAY ONE...THIS AFTERNOON AND TONIGHT

CONVECTIVE

THUNDERSTORMS ARE EXPECTED THIS AFTERNOON AND TONIGHT ESPECIALLY
WEST OF INTERSTATE 27. THE BEST CHANCE FOR SEVERE THUNDERSTORMS
WILL BE OVER THE EXTREME SOUTHWEST PANHANDLE AND WESTERN SOUTH
PLAINS WHERE HIGH SHEAR VALUES WILL INTERACT WITH MARGINAL CAPE
AND ABUNDANT LOW LEVEL MOISTURE. THE MAIN THREATS WILL BE LARGE
HAIL AND ISOLATED TORNADOES.

FLOODING

HEAVY DOWNPOURS WILL LIKELY DEVELOP TONIGHT AS LARGE SCALE ASCENT
INCREASES OVER THE SOUTH PLAINS. EXCESSIVE RUNOFF WILL CAUSE AREAS
OF LOW LYING AND POOR DRAINAGE FLOODING. LOCALIZED FLASH FLOODING
MAY BE A CONCERN BY SUNDAY MORNING ESPECIALLY OVER WESTERN
SECTIONS.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY

ADDITIONAL SHOWER AND THUNDERSTORM DEVELOPMENT CAN BE EXPECTED
SUNDAY AND MONDAY AS REMNANTS FROM HURRICANE NORBERT MOVE OVER THE
SOUTH PLAINS. HEAVY RAINFALL AND THE POTENTIAL FOR FLOODING WILL
BE THE MAIN THREATS.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION MAY BE REQUIRED ACROSS THE WESTERN SOUTH PLAINS
AND SOUTHWEST PANHANDLE LATE THIS AFTERNOON AND EVENING.

SPECIAL WEATHER STATEMENT
Issue Date: 633 AM CDT SAT OCT 11 2008
Expiration: 400 PM CDT SAT OCT 11 2008

...HEAVY RAINFALL POSSIBLE ACROSS THE SOUTH PLAINS AND SOUTHERN
TEXAS PANHANDLE SATURDAY THROUGH TUESDAY...

THE COMBINATION OF A STRONG UPPER LEVEL STORM SYSTEM OVER THE
WESTERN UNITED STATES AND TROPICAL MOISTURE ASSOCIATED WITH A
DECAYING EASTERN PACIFIC HURRICANE WILL RESULT IN PERIODS OF HEAVY
RAINFALL FOR THE AREA THROUGH THE WEEKEND. IN ADDITION...A COLD
FRONT IS EXPECTED TO MOVE SOUTH ACROSS THE REGION MONDAY
BRINGING AN ADDITIONAL FOCUS FOR HEAVY RAINFALL INTO EARLY NEXT WEEK.

ALTHOUGH IT IS TOO EARLY TO PINPOINT EXACTLY WHERE THE HEAVIEST
RAINFALL MAY OCCUR...WIDESPREAD RAINFALL AMOUNTS OF 1 TO 3 INCHES
WILL BE POSSIBLE ACROSS MOST OF THE SOUTH PLAINS AND SOUTHERN
PANHANDLE BY LATE TUESDAY. SOME LOCATIONS COULD EASILY SEE RAIN
TOTALS IN EXCESS OF 4 INCHES GIVEN THE PROLONGED NATURE OF THIS
EVENT. LOCATIONS OFF THE CAPROCK ARE EXPECTED TO GENERALLY SEE
LESSER AMOUNTS BUT THIS COULD CHANGE IF THE SYSTEM WERE TO SPEED
UP OR THE AXIS OF MOISTURE SHIFT EAST.

ALTHOUGH WIDESPREAD FLOODING IS NOT EXPECTED AT THIS TIME THE
LIKELIHOOD OF EXCESSIVE RUNOFF WILL INCREASE AS THUNDERSTORMS
REDEVELOP AND MOVE OVER THE SAME AREA. AS FORECASTS BECOME MORE
CLEAR AS TO WHERE AND WHEN THIS MAY HAPPEN...A FLOOD WATCH WILL BE
CONSIDERED.
