PREV DISCUSSION... /ISSUED 338 AM CDT MON SEP 28 2009/

DISCUSSION...
THIS MORNING`S MODEL RUNS (AND THE PAST SEVERAL) HAVE BEEN
CONSISTENT IN USHERING A WEAK FRONT INTO THE AREA TONIGHT INTO
EARLY TUESDAY. THE FRONT..ENTERING THE RED RIVER VALLEY TO THE
SOUTH PLAINS AT THE MOMENT..WILL PUSH SOUTH ACROSS NORTH AND CENTRAL
TEXAS TODAY..POISED ALONG OUR NORTHERN CWA BORDER BY MIDDAY. S/W
ENERGY IN THE UPPER LEVELS WILL COMBINE WITH LOW LEVEL CONVERGENCE
ALONG THE WEAK FRONTAL BOUNDARY TO PRODUCE AT LEAST A SLIGHT CHANCE
OF THUNDERSTORMS DURING THE AFTERNOON AND EVENING. A SHALLOW
OVERRUNNING PATTERN WILL BEGIN TONIGHT AS THE FRONT PUSHES THROUGH
THE ENTIRE CWA. HEAVIER AMOUNTS OF RAIN HOWEVER WILL REMAIN FOCUSED
ALONG AND JUST AHEAD OF THE FRONT OVER OUR SOUTHERN SECTIONS
TONIGHT. AS SURFACE WINDS BECOME SOUTHEAST TOMORROW AFTERNOON..
OVERRUNNING PRECIPITATION SHOULD END BUT WEAK SURFACE CONVERGENCE
AND GULF MOISTURE SHOULD BE ENOUGH FOR A SLIGHT CHANCE OF SHOWERS
AND THUNDERSTORMS OVER ALL BUT NORTHERN AND WESTERN SECTIONS.
DISTURBANCES WILL MOVE NORTHEAST OF THE CWA TUESDAY NIGHT AS
UPPER LEVEL RIDGING BUILDS IN FROM THE WEST. A WEAK WEST NORTHWEST
FLOW ALOFT AND SOUTHEAST FLOW AT THE SURFACE SHOULD RESULT IN
WIDESPREAD STRATUS DEVELOPMENT TUESDAY NIGHT. AS RIDGING ALOFT
CONTINUES WEDNESDAY WITH SOME UPPER PACIFIC MOISTURE MOVING EAST
ON THE BACKSIDE OF THE RIDGE..READINGS WILL BE AT OR SLIGHTLY
ABOVE SEASONAL NORMS. A PROGRESSIVE UPPER TROUGH ENTERING THE
SOUTHERN U.S. PLAINS THURSDAY WILL BRING ENHANCED WESTERLIES TO
THE REGION WITH ANOTHER DAY OF ABOVE NORMAL READINGS. DRIER AIR
WILL ADVECT INTO THE AREA FRIDAY AS THE PROGRESSIVE UPPER TROUGH
PULLS EAST WITH HIGHS AGAIN ABOVE NORMAL. THE SOUTHERN BRANCH
OF THE JET WILL CAUSE THE WEAK FRONT TO WAVE ALONG THE COAST
WITH SHOWERS AND STORMS OVER SOUTHEAST PORTIONS OF THE CWA FRIDAY
NIGHT. DISTURBANCES EMBEDDED WITHIN THE SOUTHERN BRANCH WILL
PRODUCE SCATTERED SHOWERS AND THUNDERSTORMS THROUGH THE WEEKEND
PERIOD.
