POLK COUNTY IS ABNORMALLY DRY DUE TO AN ANNUAL RAINFALL DEFICIT.
RECENT RAINS HAVE REDUCED THE DEFICIT SIGNIFICANTLY. THE LAST TWO
DAYS (AUG 11 AND AUG 12) HAVE BEEN RELATIVELY KIND WITH SCATTERED
THUNDERSTORMS DEVELOPING EACH AFTERNOON. ANNUAL RAINFALL DEFICITS
ARE EXTREME OVER A LARGE PORTION OF SOUTHEAST TEXAS. THE RECENT RAIN
HAS BEEN VERY WELCOME AND HELPFUL BUT THERE IS A LONG WAY TO GO
BEFORE RAINFALL RETURNS TO NORMAL LEVELS AND DROUGHT CONDITIONS EASE.

BELOW IS A BRIEF DESCRIPTION OF EACH DROUGHT CLASSIFICATION:

D4 EXCEPTIONAL DROUGHT - EXCEPTIONAL OR WIDESPREAD CROP/PASTURE LOSS
   A SHORTAGE OF WATER IN RESERVOIRS AND STREAMS CREATING
   A WATER EMERGENCY.

D3 EXTREME DROUGHT - MAJOR CROP OR PASTURE LOSSES. WIDESPREAD WATER
   SHORTAGES AND RESTRICTIONS.

D2 SEVERE DROUGHT - CROP OR PASTURE LOSSES LIKELY. SOME WATER
   SHORTAGES COMMON AND SOME WATER RESTRICTIONS IMPOSED.

D1 MODERATE DROUGHT - SOME DAMAGE TO CROPS AND PASTURES. RESERVOIRS OR
   WELLS LOW. VOLUNTARY WATER RESTRICTIONS IMPOSED.

D0 ABNORMALLY DRY - SHORT TERM DRYNESS. PLANT GROWTH SLOWS. MINOR
   WATER DEFICITS.

HTTP://WWW.DROUGHT.UNL.EDU/DM/DM_STATE.HTM?TX.S OR FOR THE ENTIRE
COUNTRY SEE...HTTP://WWW.DROUGHT.UNL.EDU/DM/MONITOR.HTML.

AGRICULTURAL IMPACTS...
THE LATEST SOIL MOISTURE ANOMALY GRAPHIC FROM THE CLIMATE PREDICTION
CENTER SHOWS MODERATELY DRY SOIL CONDITIONS OVER THE EXTREME EAST
AND NORTHEAST WITH SEVERELY DRY SOIL CONDITIONS OVER THE SOUTHWEST
PORTION OF SOUTHEAST TEXAS. THE AUGUST 11TH TEXAS A & M TEXAS CROP
AND WEATHER REPORT INDICATED THAT RECENT RAINS HAVE HELPED SOME
PASTURES RECOVER BUT ADDITIONAL RAIN WAS NECESSARY TO SUSTAIN
GROWTH. LIVESTOCK WERE DOING CONSIDERABLY BETTER AND POND LEVELS HAD
RISEN OVER EASTERN AND NORTHEASTERN PARTS OF THE REGION.

FOR MORE INFORMATION...SEE HTTP://AGNEWS.TAMU.EDU (ALL LOWER CASE).

HYDROLOGIC IMPACTS...
RIVER LEVELS HAVE REMAINED NEAR NORMAL LEVELS OVER THE NORTHERN AND
EASTERN PORTIONS OF THE REGION. AREA RESERVOIRS WERE NEAR CAPACITY
OVER THE EAST AND WELL BELOW NORMAL OVER THE WEST.

     WATERSHED                   CAPACITY

LAKE SOMERVILLE                   75.8 PERCENT
LAKE TEXANA                       59.0 PERCENT

FIRE DANGER IMPACTS...
RECENT RAINS IN LATE JULY HAVE REDUCED THE FIRE WEATHER THREAT BUT
THE AREA HAS BEGUN TO DRY AGAIN. A MODERATE TO HIGH FIRE DANGER
PERSISTS OVER THE SOUTHWEST HALF OF THE AREA. DUE TO HEAVIER RAIN
OVER THE NORTHEAST HALF OF THE REGION...THE BURN BAN PREVIOUSLY IN
EFFECT FOR POLK COUNTY HAS BEEN LIFTED. HIGH RELATIVE HUMIDITY
VALUES WILL ALLOW FOR SOME RECOVERY AT NIGHT BUT EXTREME DAYTIME
TEMPERATURES...AVERAGING 3 TO 4 DEGREES ABOVE NORMAL WILL INCREASE
THE FIRE WEATHER THREAT.

AS OF AUGUST 13TH...RECENT RAINS HAVE HELPED TO IMPROVE THE
KEETCH-BYRAM DROUGHT INDICES OVER PARTS OF SOUTHEAST TEXAS. KBDI
VALUES REMAINED NEAR CRITICAL VALUES OVER FAR WESTERN COUNTIES DUE
TO TEMPERATURES ABOVE 100 DEGREES AND THE LACK OF RAINFALL. BELOW IS
A TABLE WITH KBDI VALUES (08/04/2009):

WHICH INVOLVE FIRE OR SPARKS...BY MAKING SURE WATER IS QUICKLY
AVAILABLE IF AN UNWANTED FIRE OR SMOLDERING BEGIN. FINALLY...
MOTORISTS SHOULD NOT DISCARD LIGHTED CIGARETTES FROM THEIR VEHICLES.

OUTLOOK...
WEAK UPPER LEVEL RIDGING OVER THE SOUTHEAST UNITED STATES WILL
EXTEND INTO SOUTHEAST TEXAS OVER THE WEEKEND. DIURNALLY DRIVEN
SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE FRIDAY AND SATURDAY.
A WEAK INVERTED TROUGH WILL APPROACH DEEP SOUTH TEXAS ON SUNDAY.
SLIGHTLY DEEPER MOISTURE ON THE EAST SIDE OF THIS FEATURE WILL BRING
ADDITIONAL SHOWERS AND THUNDERSTORMS TO THE REGION SUNDAY AND
MONDAY. THE APPROACH OF A LONG WAVE TROUGH WILL BRING ADDITIONAL
RAIN CHANCES FOR MUCH OF NEXT WEEK. IS IT A DROUGHT BUSTER? PROBABLY
NOT. WILL IT ALLEVIATE SOME OF THE SHORT TERM DROUGHT EFFECTS? FIRST
GUESS IS PROBABLY YES.

THE NEXT DROUGHT INFORMATION STATEMENT WILL BE ISSUED ON OR AROUND
AUGUST 20 2009.
