...WARMEST AUGUST ON RECORD FOR THE CITIES OF HOUSTON...COLLEGE
STATION AND GALVESTON...

...WARMEST ALL TIME AVERAGE MONTHLY TEMPERATURE FOR THE CITY OF
HOUSTON...

ANYONE WHO HAS LIVED HERE A WHILE IS AWARE THAT SUMMERS CAN BE...
AND USUALLY ARE...HOT AND HUMID. AUGUST 2010 IS ONE FOR THE RECORD
BOOKS. ALL FOUR PRIMARY CLIMATE SITES ESTABLISHED THEIR WARMEST
AVERAGE MONTHLY TEMPERATURE FOR THE MONTH OF AUGUST. BELOW IS A
LISTING OF THE FIVE WARMEST AUGUSTS FOR EACH OF THE PRIMARY
CLIMATE SITES:

       HOUSTON     COLLEGE     GALVESTON     HOUSTON
                   STATION                   HOBBY APRT

       87.7 2010   89.1 2010   87.3 2010     86.9 2010
       87.5 1962   88.5 1951   86.6 2005     86.4 1999
       87.1 1951   87.7 1962   86.5 2009     86.2 2009
       86.8 1999   87.6 2009   86.1 1999     85.9 1962
       86.8 1902   87.4 1988   85.8 1995     85.8 1951

THE MONTHLY AVERAGE TEMPERATURE WAS ALSO EITHER THE WARMEST
AVERAGE MONTHLY TEMPERATURE EVER RECORDED OR THE SECOND WARMEST
MONTHLY AVERAGE TEMPERATURE RECORDED AT ALL FOUR PRIMARY CLIMATE
SITES. HOUSTON HAS NEVER ENDURED A MONTH - ANY MONTH - AS HOT AS
AUGUST 2010. BELOW IS A TABLE WITH THE FIVE WARMEST AVERAGE MONTHLY
TEMPERATURES:

    HOUSTON        COLLEGE        GALVESTON        HOUSTON

SO...WHY THE HEAT? A PERSISTENT UPPER LEVEL RIDGE OF HIGH PRESSURE
REMAINED OVER THE SOUTHERN PLAINS SINCE THE END OF JULY. THE RIDGE
WOULD SHIFT EVER SO SLIGHTLY BUT REMAINED CLOSE ENOUGH TO SUPPRESS
RAIN CHANCES AND KEEP CLOUDS AWAY. SURFACE DEW POINT TEMPERATURES
WERE ALSO HIGHER THAN NORMAL. OVERNIGHT LOW TEMPERATURES WILL NOT
FALL BELOW THE DEW POINT TEMPERATURE SO ELEVATED DEW POINTS WILL
PRODUCED UNUSUALLY WARM OVERNIGHT LOW TEMPERATURES. DURING AUGUST
2010...OVERNIGHT LOW TEMPERATURES STRUGGLED TO FALL BELOW 80
DEGREES MOST NIGHTS. WITH WARM STARTS TO THE DAY...MAXIMUM
TEMPERATURES HAD NO TROUBLE CLIMBING ABOVE THE 30 YEAR
CLIMATOLOGICAL NORMALS. THE HIGH DEW POINTS ALSO HELPED TO PRODUCE
VERY HIGH RELATIVE HUMIDITY VALUES. THESE VALUES COMBINED WITH
VERY WARM TEMPERATURES PRODUCED HIGH HEAT INDEX VALUES...
EXCEEDING 110 DEGREES DURING THE MIDDLE AND LATTER HALF OF THE
MONTH.

THE HEAT WASN`T THE ONLY STORY OF THE MONTH. RAINFALL...OR THE
LACK THEREOF WAS ALSO A PLAYER. AUGUST WAS A VERY DRY MONTH AND
WAS ON TARGET TO BE ONE OF THE TOP FIVE DRIEST AUGUSTS ON RECORD.
HOWEVER...SCATTERED SHOWERS AND THUNDERSTORMS ON THE 30TH AND 31ST
BROUGHT SOME MUCH NEEDED RAIN TO SOUTHEAST TEXAS. GALVESTON STILL
RECORDED IT`S NINTH DRIEST AUGUST ON RECORD WITH THOSE RECORDS
DATING BACK TO 1875. DESPITE THE LACK OF RAIN...THE U.S. DROUGHT
MONITOR ONLY HAS THE NORTHEAST HALF OF THE AREA CATEGORIZED AS
ABNORMALLY DRY.
