PUBLIC INFORMATION STATEMENT
NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX
220 PM CDT THU MAY 17 2012

       ...THE FIRST FIVE MONTHS OF 2012 BRING MUCH NEEDED RAIN
                     TO MUCH OF SOUTHEAST TEXAS...

LOCALLY HEAVY RAIN FELL OVER PARTS OF SOUTHEAST TEXAS DURING THE FIRST
HALF OF THE MONTH. AREAS FROM RICHMOND TO SOUTH HOUSTON TO TEXAS CITY
RECEIVED RAINFALL IN EXCESS OF FOUR INCHES LAST WEEKEND WITH ADDITIONAL
RAIN EARLIER THIS WEEK. THE FREQUENT AND AT AT TIMES HEAVY RAIN OF 2012
HAS STOOD IN STARK CONTRAST TO THE DROUGHT OF 2011. THE FOUR MONTH PERIOD OF
FEBRUARY...MARCH...APRIL AND MAY OF 2011 WAS ONE OF THE DRIEST PERIODS ON
RECORD AND IT WAS THE FIRST TIME IN RECORDED HISTORY THAT THE CITY OF
HOUSTON ENDURED FOUR CONSECUTIVE MONTHS WITH RAINFALL BELOW AN INCH.
COMPARED TO 2011...2012 HAS BEEN THE YEAR OF PLENTY. MOST LOCATIONS HAVE
RECEIVED RAINFALL IN 2012 THAT IS AT LEAST TEN INCHES GREATER THAN RAINFALL
RECEIVED THROUGH THE END OF MAY IN 2011. THE COMMUNITY OF RICHMOND HAS
REPORTED 35.35 INCHES OF RAIN THUS FAR IN 2012. LAST YEAR...RICHMOND ONLY
RECORDED 3.99 INCHES OF RAIN BY THE END OF MAY. THAT IS A DIFFERENCE OF
31.36 INCHES OF RAIN. THE 30 YEAR CLIMATE NORMALS SUGGEST THAT RICHMOND
SHOULD RECEIVE 17.02 INCHES OF RAIN BY THE END OF MAY. IT APPEARS THAT
WHEN IT COMES TO RAINFALL ACROSS SOUTHEAST TEXAS...IT IS FEAST OR FAMINE.
OTHER LOCATIONS ACROSS SOUTHEAST TEXAS THAT HAVE SEEN RAINFALL DIFFERENCES
BETWEEN 2011 AND 2012 GREATER THAN 20 INCHES INCLUDE HOUSTON HOBBY AIRPORT
AND THE CO-OP SITE AT HOUSTON WESTBURY.

BELOW IS A TABLE CONTAINING RAINFALL DATA FOR SEVERAL COMMUNITIES ACROSS
SOUTHEAST TEXAS THAT SHOWS THE DIFFERENCE BETWEEN 2011 AND 2012. THE
RAINFALL DIFFERENCE BETWEEN YEARS IS TRULY REMARKABLE.

LOOKING AHEAD...IT APPEARS THAT UPPER LEVEL RIDGING WILL DEVELOP AND EXPAND
OVER SOUTHEAST TEXAS THROUGH THE END OF THE MONTH. RAIN CHANCES WILL DWINDLE
AND HEAT WILL RETURN. THE RAINS OVER THE FIRST FIVE MONTHS OF THE YEAR HAS
HELPED TO REPLENISH AREA RIVERS AND RESERVOIRS. OVERALL...SOUTHEAST TEXAS IS
IN REASONABLY GOOD SHAPE TO HANDLE AN EXTENDED DRY PERIOD SHOULD ONE DEVELOP.
