EARLY AFTERNOON RADAR IMAGERY SHOWS ISOLATED TO SCATTERED RAIN
SHOWERS DEVELOPING OVER PORTIONS OF THE BRAZOS VALLEY AND THE
PINEY WOODS IN ASSOCIATION WITH A SHORTWAVE IMPULSE EMBEDDED
WITHIN SOUTHWESTERLY FLOW ALOFT ALONG WITH DAYTIME HEATING AND
SUFFICIENT INSTABILITY. WE WILL KEEP RAIN CHANCES BETWEEN 20-40
PERCENT OVER THESE AREAS THROUGH THE REMAINDER OF THE AFTERNOON
AND MUCH LOWER AROUND 10% NEAR THE COAST. ISOLATED TO SCATTERED
CONVECTION SHOULD DIMINISH BY EARLY THIS EVENING. THE SOUTHWESTERLY
FLOW PATTERN ALOFT WILL PERSIST ACROSS SOUTHEAST TEXAS THROUGH
THE END OF THE WEEK, WHILE LIGHT TO MODERATE ONSHORE FLOW PREVAILS
AT THE SURFACE. WARM AND HUMID CONDITIONS WILL CONTINUE EACH DAY
UNDERNEATH PARTLY TO MOSTLY CLOUDY SKIES. RAIN CHANCES WILL
OVERALL REMAIN VERY LOW WITH LITTLE IN THE WAY OF FORCING EXPECTED
THROUGH FRIDAY, THOUGH ISOLATED SHOWERS OR THUNDERSTORMS COULD
CLIP OUR FAR NORTHERN COUNTIES ON WEDNESDAY.
AN UPPER LEVEL TROUGH IS EXPECTED TO MOVE ACROSS THE CENTRAL
PLAINS AND THE UPPER MIDWEST ON SATURDAY. AN ASSOCIATED COLD FRONT
MAY APPROACH OUR FORECAST AREA BY SATURDAY AFTERNOON AND EVENING
ALONG WITH AN INCREASED CHANCE OF SHOWERS AND THUNDERSTORMS

CONTINUE INTO THE DAY SUNDAY BEHIND THE FRONTAL PASSAGE.
NORTHEASTERLY WINDS ARE EXPECTED TO INCREASE SATURDAY NIGHT INTO
SUNDAY BEHIND THE COLD FRONT, ESPECIALLY OVER THE OFFSHORE WATERS.
