AND A DRYLINE FROM THE WEST...STRONG GUSTY SOUTH WINDS OCCURRED
ACROSS WEST CENTRAL TEXAS ON THE 5TH. PEAK WIND GUSTS REACHED
52 MPH AT ABILENE AND 45 MPH AT SAN ANGELO. A LINE OF THUNDERSTORMS
MOVED EAST INTO THE BIG COUNTRY. STRONG WINDS FROM THESE STORMS

DURING THE MIDDLE PART OF THE MONTH...THE UPPER LEVEL HIGH
PRESSURE SYSTEM SHIFTED INTO THE SOUTHWESTERN STATES...AND
WEST CENTRAL TEXAS WAS SITUATED ON THE EASTERN PERIPHERY OF
THIS SYSTEM. WITH THIS PATTERN AND A NORTHWEST FLOW ALOFT
INTO THE REGION...THUNDERSTORM COMPLEXES AFFECTED PARTS OF WEST
CENTRAL TEXAS ON SEVERAL OCCASIONS. ON THESE OCCASIONS...THE
STORMS TYPICALLY DEVELOPED ACROSS THE REGION FROM NORTHEASTERN
NEW MEXICO AND THE TEXAS AND OKLAHOMA PANHANDLES INTO WESTERN
KANSAS. AFTER THESE STORMS DEVELOPED DURING THE AFTERNOON AND
EVENING HOURS...THEY ORGANIZED INTO CLUSTERS OR COMPLEXES AND
THEN TRACKED SOUTH AND SOUTHEAST TOWARD WEST CENTRAL TEXAS.

A MORE WIDESPREAD SEVERE WEATHER EVENT WITH STRONG WINDS

A THUNDERSTORM COMPLEX MOVED SOUTH AND SOUTHEAST ACROSS
ROUGHLY THE NORTHERN HALF OF WEST CENTRAL TEXAS...AND
SCATTERED STORMS OCCURRED FARTHER TO THE SOUTH. WINDS OF 60
TO 70 MPH OCCURRED ACROSS THE BIG COUNTRY. THIS CAUSED SOME

A PEAK WIND GUST OF 49 MPH OCCURRED AT THE SAN ANGELO REGIONAL
AIRPORT WHEN THE LEADING EDGE OF THIS THUNDERSTORM COMPLEX
ARRIVED SHORTLY AFTER MIDNIGHT. HEAVY RAINFALL CAUSED FLOODING
OF SOME HIGHWAYS IN JONES COUNTY AROUND STAMFORD.

SHOWERS AND STORMS CONTINUED INTO THE EARLY MORNING HOURS OF
THE 20TH ACROSS SOUTHERN SECTIONS OF WEST CENTRAL TEXAS. FOR
THIS EVENT...WITH THE EXCEPTION OF CROCKETT COUNTY...RAINFALL
TOTALS WERE MOSTLY IN THE RANGE OF ONE HALF INCH TO 1.5 INCHES

JUNCTION. LOCALIZED RAINFALL AMOUNTS WERE OVER AN INCH.
FROM THE 22ND THROUGH THE 27TH...A HIGH PRESSURE SYSTEM
ALOFT REMAINED OVER NORTHERN MEXICO AND NEW MEXICO. THIS
SYSTEM WAS THE PREVAILING WEATHER INFLUENCE ON WEST CENTRAL
TEXAS WITH MOSTLY DRY CONDITIONS AND TEMPERATURES SLIGHTLY
ABOVE NORMAL.

BY THE 28TH...A CHANGE IN THE FLOW PATTERN ALOFT ALLOWED A
WEAK COLD FRONT TO APPROACH WEST CENTRAL TEXAS FROM THE
NORTH. THE APPROACH AND ARRIVAL OF THE FRONT...COMBINED
WITH A SLOW MOVING UPPER LEVEL DISTURBANCE TO BRING SHOWERS
AND THUNDERSTORMS TO MUCH OF WEST CENTRAL TEXAS. THESE
OCCURRED FROM THE LATE AFTERNOON OF THE 28TH THROUGH THE
29TH. A THUNDERSTORM PRODUCED A WIND GUST TO 60 MPH IN
HASKELL COUNTY ON LATE AFTERNOON OF THE 28TH (3 MILES WEST OF

FLOODED LOW WATER CROSSINGS IN SOUTHERN CROCKETT COUNTY. THE
FRONT STALLED ACROSS CENTRAL SECTIONS OF WEST CENTRAL TEXAS...
THEN EVENTUALLY DRIFTED SOUTH TOWARD INTERSTATE 10 ON THE 30TH.
THE PRESENCE OF THIS FRONT...COMBINED WITH THE INFLUENCE OF A
WEAK UPPER LEVEL DISTURBANCE TO THE WEST...RESULTED IN
ADDITIONAL SHOWERS AND SCATTERED THUNDERSTORMS ON THE 30TH.
THIS ACTIVITY OCCURRED ACROSS THE REGION SOUTH OF INTERSTATE 20.

FOR THE LAST 3 DAYS OF THE MONTH...THE AREA SOUTHEAST OF A LINE
FROM JUNCTION TO SAN SABA...ALONG WITH MOST OF THE BIG
COUNTRY...RECEIVED LESS THAN ONE HALF INCH OF RAIN FOR THIS
EVENT. TOTAL RAINFALL AMOUNTS IN THE 1 TO 3 INCH RANGE WERE

CENTRAL TEXAS. SCATTERED POCKETS ACROSS THE NORTHERN
