JULY 2003 WEATHER HIGHLIGHTS...

JULY WEATHER IN WEST CENTRAL TEXAS IS NORMALLY DOMINATED BY A RIDGE 
OF HIGH PRESSURE ALOFT...AND IS NORMALY HOT AND DRY. ALTHOUGH AN 
UPPER LEVEL RIDGE OF HIGH PRESSURE TO THE NORTH AND WEST OF THE 
REGION EXERTED ITS INFLUENCE DURING MUCH OF THE MONTH...A FEW 
EXCEPTIONS TO THIS WEATHER PATTERN OCCURRED DURING THIS JULY. 

EARLY IN JULY AN UPPER LEVEL DISTURBANCE MOVED INTO THE TEXAS BIG 
BEND REGION AND ALLOWED GULF MOISTURE TO MOVE INTO WEST CENTRAL
TEXAS. THIS RESULTED IN SCATTERED SHOWERS AND THUNDERSTORMS OVER THE 
CONCHO VALLEY...HEARTLAND...NORTHERN EDWARDS PLATEAU AND NORTHWEST 
HILL COUNTRY. THE INCREASED CLOUDCOVER AND SCATTERED PRECIPITATION 
BROUGHT A PERIOD OF COOLER TEMPERATURES TO WEST CENTRAL TEXAS. 

DURING THE MIDDLE OF THE MONTH...HURRICANE CLAUDETTE MADE LANDFALL
ON THE SOUTH TEXAS COAST. A LANDFALLING HURRICANE IN JULY ALONG THE 
TEXAS COAST IS QUITE UNUSUAL. ITS REMNANTS TRACKED WESTWARD ACROSS 
SOUTHERN TEXAS INTO THE BIG BEND REGION. THIS SYSTEM BROUGHT AN 
INFLUX OF MOISTURE INTO WEST CENTRAL TEXAS. SCATTERED SHOWERS AND 
THUNDERSTORMS OCCURRED...MAINLY OVER CENTRAL AND SOUTHERN SECTIONS 
OF THE REGION. THE RAINFALL WAS LOCALLY HEAVY...AND WIDELY SCATTERED 
LOCATIONS RECEIVED ONE TO TWO INCHES OF RAIN. ONCE AGAIN THE 
INCREASED CLOUDCOVER AND SCATTERED PRECIPITATION BROUGHT A PERIOD 
OF COOLER TEMPERATURES. 

IN JULY...COLD FRONTS USUALLY STALL OR DISSIPATE WELL TO THE NORTH 
OF WEST CENTRAL TEXAS. ON THE 23RD HOWEVER...A WEAK COLD FRONT WAS 
ABLE TO MOVE SOUTHWARD ACROSS WEST CENTRAL TEXAS. THIS BROUGHT 
SCATTERED SHOWERS AND THUNDERSTORMS TO SOUTHERN SECTIONS OF THE 
REGION. STRONG THUNDERSTORM WINDS BLEW OFF PART OF A ROOF IN 
ROOSEVELT (KIMBLE COUNTY).

WIDELY SCATTERED SHOWERS AND THUNDERSTORMS OCCURRED ON THE 30TH AND 
31ST...AS A SURFACE TROUGH OF LOW PRESSURE MOVED DOWN INTO THE 
REGION. RAINFALL AMOUNTS WERE GENERALLY LESS THAN ONE QUARTER OF AN 
INCH...BUT A FEW LOCATIONS RECEIVED OVER ONE HALF INCH.
