...MODERATE TO HEAVY RAIN EXPECTED ACROSS SOUTH TEXAS LATE TONIGHT
THROUGH TUESDAY ALONG WITH MUCH COLDER TEMPERATURES THIS WEEK...

A STRONG COLD MOVED THROUGH SOUTH TEXAS EARLIER THIS MORNING...
AND WILL USHER IN COLDER TEMPERATURES AND WIND FOR TODAY ALONG
WITH A BRISK NORTH WIND. TEMPERATURES WILL LIKELY HOLD STEADY IN
THE 50S TODAY...AND EVEN SLOWLY FALL IN SOME AREAS. LIGHT RAIN
WILL BE POSSIBLE TODAY THROUGH THIS EVENING AMOUNTING GENERALLY
FROM A TRACE UP TO 1/2 OF AN INCH.

AN APPROACHING UPPER LEVEL SYSTEM WILL RESULT IN INCREASING
COVERAGE AND INTENSITY OF RAINFALL ACROSS SOUTH TEXAS FROM
SOUTHWEST TO NORTHEAST AFTER MIDNIGHT TONIGHT THROUGH TUESDAY
MORNING. WIDESPREAD RAIN AND ISOLATED THUNDERSTORMS WILL OCCUR
DURING THE DAY TUESDAY AS THE UPPER LEVEL STORM SYSTEM MOVES
ACROSS SOUTH TEXAS. THE RAIN WILL BE HEAVY AT TIMES...ESPECIALLY
IN THE COASTAL BEND. PRECIPITATION WILL END QUICKLY FROM WEST TO
EAST EARLY TUESDAY EVENING. MORNING LOWS ON TUESDAY WILL BE IN THE
UPPER 40S WITH HIGHS ON TUESDAY ONLY IN THE LOW TO MID 50S.

TOTAL RAINFALL AMOUNTS FROM TODAY THROUGH TUESDAY EVENING ARE
GENERALLY EXPECTED TO BE 1 TO 3 INCHES ACROSS SOUTH TEXAS. LOCAL
AMOUNTS COULD EXCEED 4 INCHES ALONG THE COAST. ALL OF THIS RAIN
WILL CAUSE RISES IN RIVERS AND CREEKS...ESPECIALLY OVER THE
GUADALUPE RIVER BASIN SOUTH OF VICTORIA AND THE COPANO CREEK.
SINCE THE GUADALUPE RIVER AND COPANO CREEK ARE RUNNING ABOVE
NORMAL...THE RAINFALL COULD RESULT IN THE RIVER AND CREEK REACHING
MINOR FLOOD STAGE BY MID WEEK. HEAVY RAIN MAY ALSO CAUSE URBAN AND
SMALL STREAM FLOODING ACROSS THE COASTAL BEND.

CLEARING IS EXPECTED WEDNESDAY ACROSS SOUTH TEXAS...SETTING UP
NEAR FREEZING CONDITIONS FOR INLAND LOW-LYING AREAS THURSDAY AND
FRIDAY MORNINGS. AREAS NEAR THE IMMEDIATE COAST COULD DROP INTO
THE MID 30S TO LOWER 40S.
