DURING MOST OF THE MIDDLE OF THE MONTH...A HIGH PRESSURE SYSTEM

EXCEEDED 100 DEGREES FOR A NUMBER OF DAYS. THE HOTTEST

TO SAN ANGELO TO SONORA RECEIVED AMOUNTS BETWEEN ONE HALF AND

LATE IN THE MONTH THE UPPER LEVEL HIGH PRESSURE SYSTEM BUILT
BACK OVER TEXAS...AND BROUGHT A RETURN TO A HOT AND DRY
PATTERN. HIGH TEMPERATURES WERE IN THE 100 TO 105 DEGREE
RANGE ON SEVERAL DAYS.

DURING THE LAST FEW DAYS OF THE MONTH...THE UPPER LEVEL HIGH
PRESSURE SYSTEM WEAKENED AND SHIFTED WESTWARD TOWARD THE
FOUR CORNERS REGION. THIS ALLOWED A WEAK COLD FRONT TO MOVE
DOWN INTO WEST CENTRAL TEXAS ON THE 28TH BEFORE STALLING
AND WASHING OUT. A FEW WEAK DISTURBANCES ALSO MOVED DOWN
INTO WEST CENTRAL TEXAS...IN THE WEAK NORTHERLY FLOW ALOFT
WHICH DEVELOPED. THESE FEATURES BROUGHT SHOWERS AND
THUNDERSTORMS TO VARIOUS PART OF WEST CENTRAL TEXAS. A FEW
LOCATIONS RECEIVED OVER 2 INCHES OF RAINFALL. A NUMBER OF
OTHER LOCATIONS RECEIVED 1 TO 2 INCHES OF RAIN.
