DURING MOST OF SEPTEMBER...HOT AND DRY CONDITIONS PREVAILED IN WEST

WHEN THE HIGH PRESSURE SYSTEM WAS CENTERED DIRECTLY OVER THE REGION.

HURRICANE RITA MADE LANDFALL ON THE GULF COAST NEAR THE TEXAS/
LOUISIANA STATE BORDER EARLY ON THE 24TH...BEFORE MOVING SLOWLY
NORTHWARD. THIS TROPICAL SYSTEM WAS TOO FAR AWAY FROM WEST CENTRAL
TEXAS TO BRING ANY RAINFALL TO THE AREA.

TIME...TEMPERATURES OVER 100 DEGREES WERE RECORDED ACROSS AREAS OF
WEST CENTRAL TEXAS. THESE WERE AMONG THE HOTTEST TEMPERATURES FOR

SOUTHWARD ACROSS WEST CENTRAL TEXAS ON THE EVENING OF THE 28TH.
GUSTY NORTH WINDS BEHIND THIS FRONT GENERATED BLOWING DUST AT A FEW
LOCATIONS. ABILENE RECORDED A PEAK WIND GUST OF 40 MPH. THE PASSAGE
OF THIS FRONT BROUGHT AN END TO THE UNUSUALLY HOT CONDITIONS. HIGH
PRESSURE WITH AN APPRECIABLY COOLER AIRMASS SETTLED INTO THE REGION
ON THE 29TH INTO THE 30TH. TEMPERATURES DROPPED INTO THE 50S FOR
LOWS ACROSS MOST OF WEST CENTRAL TEXAS ON THE 30TH. THESE WERE THE

AFTERNOON AND NIGHTTIME HOURS OF THE 30TH...AS A STRONG UPPER LEVEL
DISTURBANCE MOVED ACROSS OKLAHOMA. A SEVERE STORM PRODUCED GOLFBALL
SIZE HAIL IN NORTHWESTERN HASKELL COUNTY...AROUND ROCHESTER AND
OBRIEN. IN ADDITION...A PEANUT ELEVATOR WAS BLOWN DOWN IN ROCHESTER.

LONGWORTH TO ANSON TO FORT GRIFFIN. SOME LOCATIONS IN THIS AREA
RECEIVED RAINFALL AMOUNTS OF ONE HALF TO ONE INCH...WITH LOCALIZED
HIGHER AMOUNTS.
