                   ...DROUGHT INFORMATION STATEMENT...

        ...DRIEST MAY 1ST THROUGH JUNE 28TH RECORDED IN HOUSTON...

            ...HIGHER RAIN CHANCES TODAY AND TUESDAY...

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 RIDGE INTENSIFIED EARLY LAST WEEK AND HAS PRODUCED UNSEASONABLY
WARM TEMPERATURES...EXCEEDING 100 DEGREES AT TIMES. RAINFALL HAS
BEEN VIRTUALLY NON-EXISTENT. ON JUNE 24TH AND AGAIN ON THE
26TH...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 106 DEGREES. THE RIDGE HAS WEAKENED SLIGHTLY
AND HAS PUSHED A BIT FURTHER WEST. THIS WILL ALLOW A WEAK BOUNDARY
TO PUSH INTO TEXAS. SHOWERS AND THUNDERSTORMS WILL DEVELOP ALONG THE
BOUNDARY THIS AFTERNOON AND EVENING AND AGAIN TUESDAY AND WEDNESDAY.
ALTHOUGH RAINFALL IS NOT EXPECTED TO BE HEAVY...ANY RAIN WILL BE
HELPFUL. THE CLOUDS WILL ALSO HELP TO RETARD HEATING SO HIGH
TEMPERATURES ARE EXPECTED TO TREND COOLER FOR A FEW DAYS.

HOUSTON INTERCONTINENTAL AIRPORT ENDURED 31 CONSECUTIVE DAYS WITHOUT
MEASURABLE RAIN. A THUNDERSTORM ON THE EVENING OF JUNE 25TH ENDED
THE DRY STREAK. 0.27 INCHES OF RAIN FELL AT THE AIRPORT. 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!

* THIS TIES FOR THE 12TH LONGEST PERIOD WITHOUT MEASURABLE RAIN.
  THE LAST TIME HOUSTON WENT 31 DAYS WITHOUT RAIN WAS FROM JULY 31
  1990 THROUGH AUGUST 30 1990.

THE PERIOD MAY 1 2009 THROUGH JUNE 28 2009 IS NOW THE DRIEST PERIOD
IN HOUSTON WEATHER HISTORY. A PALTRY 0.65 INCHES OF RAIN HAS FALLEN
OVER THE LAST 57 DAYS. THE NORMAL RAINFALL FOR THIS PERIOD IS 10.21
INCHES OR ROUGHLY 7 PERCENT OF NORMAL. BELOW IS A TABLE WITH THE
FIVE DRIEST PERIODS (MAY 1 THROUGH JUNE 26):

                    0.65 IN 2009
                    0.85 IN 1931
                    1.72 IN 1901
                    1.78 IN 1915
                    1.82 IN 1934

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
YET TO RECEIVE 10 INCHES OF RAIN THIS YEAR. MAY AND JUNE ARE
TYPICALLY TWO OF THE WETTEST MONTHS OF THE YEAR SO THIS BUILDING
DROUGHT IS OF GREAT CONCERN.

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                       96 PERCENT
HOUSTON COUNTY LAKE               95 PERCENT
LAKE HOUSTON                      97 PERCENT
LAKE SOMERVILLE                   83 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 28TH...THE HIGHEST KEETCH-BYRAM DROUGHT INDICES (600 TO
700) WERE LOCATED OVER MUCH OF THE REGION. THE COUNTIES WITH THE 600
TO 700 KBDI VALUES INCLUDE: JACKSON...BRAZORIA...MONTGOMERY...SAN
JACINTO...POLK...TRINITY...MADISON...BRAZOS...WASHINGTON...
WHARTON...WALKER...GRIMES...LIBERTY...HARRIS...BURLESON AND FORT
BEND COUNTIES. KBDI VALUES BETWEEN 500 AND 600 COVER THE REMAINDER
OF SOUTHEAST TEXAS INCLUDING: GALVESTON...CHAMBERS...MATAGORDA...
COLORADO...AUSTIN...HOUSTON AND WALLER COUNTIES. (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 28 2009...
(HTTP://TFSFRP.TAMU.EDU/WILDFIRES/DECBAN.PNG)...A BURN BAN IS IN
EFFECT FOR MADISON...WALKER...LIBERTY...CHAMBERS...GALVESTON...
MATAGORDA...HOUSTON...BRAZORIA...HARRIS...AUSTIN...BRAZOS...
POLK..SAN JACINTO...WHARTON...MONTGOMERY...WALLER... AUSTIN...
WASHINGTON...GRIMES AND COLORADO COUNTIES. CONDITIONS CONTINUE TO
DETERIORATE AND ADDITIONAL COUNTIES MAY INSTILL BURN BANS BEFORE THE
INDEPENDENCE DAY HOLIDAY. 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 HAS
SHIFTED SLIGHTLY WEST. THIS WILL ALLOW A DEEPENING EAST COAST UPPER
TROUGH AND ASSOCIATED SURFACE COLD FRONT TO MOVE INTO TEXAS. THIS
WILL ALLOW SCATTERED SHOWERS AND THUNDERSTORMS TO DEVELOP THROUGH
THE END OF THE MONTH. NOT EVERYONE WILL RECEIVE RAIN BUT AT THIS
POINT...ANY RAINFALL WILL HELP. TEMPERATURES WILL AVERAGE 3 TO 5
DEGREES WARMER THAN THE CLIMATOLOGICAL NORMALS FOR THIS TIME OF
YEAR. LONG RANGE MODELS ARE NOT IN GOOD AGREEMENT WITH CONDITIONS IN
BY THE END OF THE WEEK. AT THIS TIME...IT APPEARS THAT THE UPPER
RIDGE WILL STRENGTHEN AGAIN BY THE END OF THIS WEEK. UNSEASONABLY
WARM TEMPERATURES AND DRY CONDITIONS WILL REDEVELOP OVER SOUTHEAST
TEXAS. 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.
