SYNOPSIS...
SOME MINOR IMPROVEMENT IN DROUGHT CONDITIONS OCCURRED OVER PARTS OF
SOUTHEAST DURING THE LAST HALF OF JULY. THE PERSISTENT UPPER LEVEL
RIDGE RESPONSIBLE FOR THIS SUMMERS RECORD HEAT AND DROUGHT SHIFTED
WEST. THIS ALLOWED A WEAK UPPER LEVEL TROUGH TO RETROGRADE INTO
TEXAS. THE UPPER TROUGH BROUGHT SOME SLIGHTLY COOLER TEMPERATURES A
BRIEF RAINY PERIOD BEGINNING AROUND JULY 16TH AND CONTINUING THROUGH
JULY 26TH. EVEN THOUGH RAIN RETURNED...MANY LOCATIONS ARE STILL
SUFFERING THROUGH ONE OF THE DRIEST PERIODS IN RECORDED HISTORY.

COLLEGE STATION ENDURED 56 CONSECUTIVE DAYS WITHOUT RAIN. THIS TIES
THE LONGEST SUCH STREAK IN RECORDED HISTORY.

THE DROUGHT HAS BEEN MADE SIGNIFICANTLY MORE HARSH DUE TO EXCESSIVE
HEAT THAT HAS PLAGUED SOUTHEAST TEXAS SINCE EARLY JUNE. THE AVERAGE
JULY HIGH TEMPERATURE AT COLLEGE THROUGH JULY 29TH HAS BEEN 101.1
DEGREES. 23 DAYS DURING JULY HAVE REACHED OR EXCEEDED 100 DEGREES AT
EASTERWOOD FIELD. SO FAR THIS SUMMER...THE TEMPERATURE HAS REACHED
OR EXCEED 100 DEGREES 34 TIMES. THE AVERAGE HIGH TEMPERATURE IN
HOUSTON HAS BEEN 97.0 DEGREES. AT HOBBY AIRPORT...THE AVERAGE HIGH
TEMPERATURE IN JULY HAS BEEN 96.2 DEGREES. THE NORMAL HIGH
TEMPERATURE IN HOUSTON IN JULY IS 93.6 DEGREES AND IN COLLEGE
STATION IS 95.6 DEGREES. THE AVERAGE MONTHLY TEMPERATURE FOR THE
PRIMARY CLIMATE SITES HAS REMAINED AT A TORRID PACE. JULY 2009 WILL
EITHER BE THE WARMEST OR SECOND WARMEST JULY EVER RECORDED FOR
HOUSTON AND COLLEGE STATION. HERE ARE THE FIVE WARMEST JULY AVERAGE

COUNTRY SEE...HTTP://WWW.DROUGHT.UNL.EDU/DM/MONITOR.HTML.

AGRICULTURAL IMPACTS...
THE LATEST SOIL MOISTURE ANOMALY GRAPHIC FROM THE CLIMATE PREDICTION
CENTER SHOWS SEVERELY DRY SOIL CONDITIONS OVER ALL OF SOUTHEAST
TEXAS. THE JULY 7TH TEXAS A & M TEXAS CROP AND WEATHER REPORT
INDICATED THAT CATTLE PRODUCERS WERE AGGRESSIVELY CULLING COW HERDS
AND MARKETING CALVES EARLY. THE CONDITION OF CORN AND SORGHUM
CONTINUED TO DETERIORATE. POND LEVELS CONTINUE TO DROP. FOR MORE
INFORMATION...SEE HTTP://AGNEWS.TAMU.EDU (ALL LOWER CASE).

HYDROLOGIC IMPACTS...
RECENT RAINFALL HAS HELPED TO REPLENISH AREA RESERVOIRS BUT THE
INTENSE HEAT AND STRONGER WINDS HAVE INCREASED EVAPORATIVE EFFECTS
AND LAKE LEVELS HAVE FALLEN SLIGHTLY SINCE THE LAST DROUGHT
STATEMENT.

LAKE TEXANA                       61 PERCENT

FIRE DANGER IMPACTS...
A HIGH FIRE DANGER EXISTS OVER SOUTHEAST TEXAS. HIGH RELATIVE
HUMIDITY VALUES WILL ALLOW FOR SOME RECOVERY AT NIGHT BUT EXTREME
DAYTIME TEMPERATURES...AVERAGING 4 TO 6 DEGREES ABOVE NORMAL WILL
INCREASE THE FIRE WEATHER THREAT. DRY GROUND FUELS WILL ALSO
INCREASE THE THREAT FOR WILD FIRES.

AS OF JULY 29TH...RAINS FROM LAST WEEK HAVE HELPED TO IMPROVE THE
KEETCH-BYRAM DROUGHT INDICES OVER THE EASTERN HALF 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 (07/29/2009):

OUTLOOK...
RAIN IS FALLING ACROSS THE NORTHERN HALF OF THE REGION THIS MORNING.
MOST AREAS NORTH OF HIGHWAY 105 RECEIVED BETWEEN A HALF AND ONE INCH
OF RAIN WITH A FEW LUCKY SPOTS IN THE BRAZOS VALLEY PICKING UP CLOSE
TO TWO INCHES OF RAIN. A WEAK BOUNDARY WILL GRAZE THE REGION ON
FRIDAY BRINGING ANOTHER CHANCE OF RAIN. THE FIRST WEEK OF AUGUST
LOOKS TO BE UNSEASONABLY WARM AND DRY AS UPPER LEVEL RIDGING
DOMINATES AREA WEATHER.

THE NEXT DROUGHT INFORMATION STATEMENT WILL BE BE ISSUED ON OR
AROUND AUGUST 6 2009.
