SYNOPSIS...
A PERSISTENT UPPER LEVEL RIDGE OF HIGH PRESSURE OVER SOUTHEAST TEXAS HAS
SHUNTED STORM SYSTEMS TO THE NORTH AND WEST OF SOUTHEAST TEXAS. THE
LAST SIGNIFICANT RAIN TO AFFECT THIS AREA OCCURRED DURING APRIL. THE
RIDGE INTENSIFIED EARLY LAST WEEK. THE STRONGER RIDGE HAS PRODUCED
UNSEASONABLY WARM TEMPERATURES...EXCEEDING 100 DEGREES AT TIMES.
RAINFALL HAS BEEN VIRTUALLY NON-EXISTENT. ON JUNE 24TH...HOUSTON
RECORED A HIGH TEMPERATURE OF 104 DEGREES WHICH IS THE HIGHEST
TEMPERATURE EVER RECORDED FOR THE MONTH OF JUNE. COLLEGE STATION AND
HUNTSVILLE ALSO RECORDED BRUTALLY HIGH TEMPERATURES ON THE 24TH...
REGISTERING 105 AND 106 DEGREES RESPECTIVELY.

CURRENTLY...HOUSTON INTERCONTINENTAL AIRPORT HAS GONE 31 CONSECUTIVE
DAYS WITHOUT MEASURABLE RAIN. THE DRIEST STRETCH OF WEATHER EVER
RECORDED FOR HOUSTON WAS BACK IN 1904. THERE WAS NO MEASURABLE RAIN
BETWEEN JANUARY 8 1904 AND FEBRUARY 16 1904 - 40 DAYS! BELOW IS A
TABLE WITH THE DRIEST PERIODS ON RECORD

OTHER COMMUNITIES ACROSS SOUTHEAST TEXAS HAVE SUFFERED A SIMILAR
FATE. COLLEGE STATION...HUNTSVILLE AND CONROE HAVE NOT RECORDED
MEASURABLE RAINFALL DURING JUNE. ANGLETON...BAY CITY AND EDNA HAVE

BELOW IS A TABLE WITH THE ANNUAL RAINFALL...NORMAL RAIN AND THE
PERCENT OF RAIN WHICH FELL IN MARCH AND APRIL AND THE PERCENT OF THE
ANNUAL RAINFALL WHICH FELL DURING THE LAST TWO WEEKS OF APRIL. THE
VALUE IN PARENTHESES IS THE INCHES OF RAIN MEASURED DURING THE
RESPECTIVE TIME PERIODS.

DON`T BE DECEIVED BY THE ANNUAL DEPARTURE FROM NORMAL. A WHOPPING 86
PERCENT OF THE 2009 ANNUAL RAINFALL FELL IN MARCH AND APRIL AND 55
PERCENT OF THE ANNUAL RAINFALL FELL DURING THE LAST TWO WEEKS OF
APRIL. ONLY 0.40 INCHES OF RAIN HAS FALLEN AT INTERCONTINENTAL
AIRPORT SINCE APRIL 29TH. THE RAIN IN APRIL HELPED TO RECHARGE AREA
RESERVOIRS...BUT THE DROUGHT LAST FALL COUPLED WITH THE EARLY SUMMER
DROUGHT IS LEAVING YARDS AND FARMS PARCHED. WITH NO OR VERY LIMITED
RAIN CHANCES EXPECTED FOR THE NEXT SEVEN DAYS...DROUGHT CONDITIONS
WILL WORSEN. HOUSTON HOBBY AIRPORT ENDURED IT`S WETTEST APRIL IN
RECORDED HISTORY AND YET STILL SUFFERS A RAINFALL DEFICIT FOR THE
YEAR BECAUSE EVERY OTHER MONTH OF THE YEAR HAD BELOW NORMAL RAINFALL.

AS OF JUNE 25 2009...THE U.S. DROUGHT MONITOR INDICATED THAT
EXCEPTIONAL DROUGHT CONDITIONS WERE AFFECTING PARTS OF JACKSON AND
BURLESON COUNTIES. EXTREME DROUGHT CONDITIONS WERE AFFECTING PARTS
OF MATAGORDA AND BRAZOS COUNTIES. SEVERE DROUGHT CONDITIONS WERE
AFFECTING PARTS OF WHARTON...COLORADO...FORT BEND...BRAZORIA...
GRIMES...MADISON...WALKER AND HOUSTON COUNTIES. MODERATE DROUGHT
CONDITIONS WERE IMPACTING PARTS OF TRINITY...MONTGOMERY...HARRIS...
WALLER...AUSTIN...GALVESTON AND CHAMBERS AND WASHINGTON COUNTIES.
ABNORMALLY DRY CONDITIONS COVERED THE REMAINDER OF SOUTHEAST TEXAS.
CONDITIONS WILL LIKELY DETERIORATE OVER THE NEXT WEEK.

FOR FURTHER CLARIFICATION...SEE EITHER (ALL LINKS IN LOWER CASE)
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 EXCESSIVELY TO ABNORMALLY DRY SOIL CONDITIONS OVER ALL
OF SOUTHEAST TEXAS. THE JUNE 24TH TEXAS A & M TEXAS CROP AND WEATHER
REPORT INDICATED THAT CROPS CONTINUE TO SUFFER FROM THE HEAT AND
DROUGHT WITH THE EXCEPTION OF RICE. CORN YIELDS ARE EXPECTED TO BE
LOW. COASTAL GRASSES WERE BROWN. SECOND HAY CUTTINGS WERE LIMITED.
IRRIGATED GRASS FIELD WERE STILL GREEN BUT WITH LIMITED GROWTH.
LIVESTOCK PRODUCERS REQUIRED SUPPLEMENTAL FEED. POND LEVELS CONTINUE
TO DROP. FOR MORE INFORMATION...SEE HTTP://AGNEWS.TAMU.EDU (ALL
LOWER CASE).

HYDROLOGIC IMPACTS...
RAINFALL NORTH OF THE REGION HAS ALLOWED RIVERS TO STAY NEAR BANKS.
THIS HAS ALLOWED AREA RESERVOIRS TO STAY NEAR CAPACITY.

     WATERSHED                   CAPACITY

LAKE LIVINGSTON                  100 PERCENT
LAKE CONROE                       97 PERCENT
HOUSTON COUNTY LAKE               96 PERCENT
LAKE HOUSTON                      98 PERCENT
LAKE SOMERVILLE                   86 PERCENT
LAKE TEXANA                       66 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 6 TO 8 DEGREES ABOVE NORMAL WILL
INCREASE THE FIRE WEATHER THREAT. DRY GROUND FUELS WILL ALSO
INCREASE THE THREAT FOR WILD FIRES.

AS OF JUNE 24TH...THE HIGHEST KEETCH-BYRAM DROUGHT INDICES (600 TO
700) WERE LOCATED OVER JACKSON...BRAZORIA...MONTGOMERY LIBERTY AND
BURLESON COUNTIES. KBDI VALUES BETWEEN 500 AND 600 COVER THE
REMAINDER OF SOUTHEAST TEXAS. (SEE THE LINK...ALL LOWER CASE
HTTP://WEBGIS.TAMU.EDU/TFS/ KBDI_DAILY/ KBDICOUNTY.PNG). INDICES
WILL LIKELY INCREASE THIS WEEK IF BELOW NORMAL RAINFALL CONTINUES.

RESTRICTIONS/ACTIONS...
ACCORDING TO THE TEXAS FOREST SERVICE WEB SITE ON JUNE 24 2009...
(HTTP://TFSFRP.TAMU.EDU/WILDFIRES/DECBAN.PNG)...A BURN BAN IS IN
EFFECT FOR MADISON...WALKER...LIBERTY...CHAMBERS...GALVESTON...
MATAGORDA...BRAZORIA...HARRIS...AUSTIN...BRAZOS...HOUSTON...POLK...
SAN JACINTO...WHARTON AND COLORADO COUNTIES. WATER RESTRICTIONS ARE
IN EFFECT FOR SOME COMMUNITIES INCLUDING PEARLAND...THE
WOODLANDS...CONROE...BAYOU VISTA...SUGARLAND AND LA MARQUE.

RESIDENTS SHOULD REMAIN VIGILANT WHEN DOING ANY OUTDOOR ACTIVITIES
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...
A PERSISTENT AND STRONG UPPER LEVEL RIDGE OF HIGH PRESSURE WILL
REMAIN ANCHORED OVER THE SOUTHERN PLAINS AND TEXAS. THIS FEATURE
WILL CONTINUE TO SHUNT WEATHER MAKERS TO THE WEST AND NORTH OF
SOUTHEAST TEXAS. TEMPERATURES WILL AVERAGE 5 TO 7 DEGREES WARMER THAN
THE CLIMATOLOGICAL NORMALS FOR THIS TIME OF YEAR. RAIN CHANCES WILL BE
VERY LOW. THE PLACEMENT OF THE UPPER RIDGE WILL DETERMINE WHEN RAIN
WILL RETURN TO SOUTHEAST TEXAS. AT THIS TIME...IT APPEARS THAT THE
UPPER RIDGE WILL EXERT INFLUENCE OVER TEXAS WEATHER THROUGH THE END
OF JUNE. RAIN CHANCES WILL REMAIN LOW AND TEMPERATURES WILL REMAIN
ABOVE SEASONAL NORMALS.

THE NEXT DROUGHT INFORMATION STATEMENT WILL BE BE ISSUED ON OR AROUND
JULY 1 2009.
