AUGUST 2006 WEATHER HIGHLIGHTS...

THE DOMINANT WEATHER FEATURE FOR MOST OF AUGUST (UNTIL THE
LAST WEEK) WAS A HIGH PRESSURE SYSTEM ALOFT...WHICH REMAINED
SITUATED OVER THE SOUTHERN PLAINS AND TEXAS. THIS RESULTED
IN PERSISTENT HOT AND DRY CONDITIONS ACROSS THE REGION. THE
RAINFALL COVERAGE FROM ANY SHOWERS AND STORMS WAS SPOTTY. A
THUNDERSTORM WIND GUST OF 46 MPH WAS RECORDED AT THE SAN
ANGELO REGIONAL AIRPORT ON THE EVENING OF THE 2ND.

A SIGNIFICANT AND MUCH NEEDED RAIN EVENT OCCURRED LATE IN THE
MONTH. THE HIGH PRESSURE SYSTEM ALOFT WEAKENED AND MOVED TO
THE EAST...ALLOWING FOR A MOISTURE INCREASE ACROSS THE REGION.
THIS COMBINED WITH THE PRESENCE OF WEAK SURFACE BOUNDARIES
SET THE STAGE FOR NUMEROUS SHOWERS AND THUNDERSTORMS. THESE
OCCURRED FROM THE 26TH TO 28TH. DURING THAT TIME...RAINFALL
TOTALS OF 1 TO 3 INCHES OCCURRED ACROSS MOST OF WEST CENTRAL
TEXAS. POCKETS OF 3 TO 5 INCH RAINFALL TOTALS OCCURRED ACROSS
THE BIG COUNTRY...CONCHO VALLEY AND INTO SCHLEICHER COUNTY...
AND ALSO ALONG A 30-MILE WIDE BAND FROM CHRISTOVAL TO
BROWNWOOD. THIS HEAVY RAINFALL CAUSED SOME MINOR FLOODING AT
SCATTERED LOCATIONS...MAINLY IN THE AREAS MORE PRONE TO
FLOODING.

THIS WAS THE MOST SIGNIFICANT RAIN EVENT TO AFFECT THE AREA
SINCE OCTOBER OF LAST YEAR.
