SURFACE BOUNDARY REMAINS STALLED ACROSS THE EASTERN SECTION OF THE
CWA...SITUATED RUFFLY FROM AROUND BOY020 SOUTHWESTWARD THRU
SOUTHEAST WILLACY COUNTY ON INTO MEXICO JUST WEST OF BROWNSVILLE.
SOME CONVECTION STARTING TO FIRE ALONG THE BOUNDARY...WITH MORE
HEADED OUR WAY FROM MEXICO...QUICKLY APPROACHING THE RIO GRANDE IN
HIDALGO COUNTY. LOOKS LIKE SOME LIFTING BEING PROVIDED BY WEAK UPPER
IMPULSE PROGGED TO MOVE NORTHEAST THRU THE AREA LATE THIS EVENING
AND EARLY TONIGHT. RUC SHOWING THE UPPER LOW TO MOVE SLOWLY EASTWARD
AND OPEN UP A BIT AS IT WEAKENS BY TOMORROW MORNING. THIS GOES ALONG
WITH GUIDANCE FROM THIS MORNING. BY 12Z...MAIN UPPER SHORTWAVE
EXPECTED FROM AROUND FORT WORTH DOWN THRU DEL RIO...WITH NOT MUCH
EXPECTED HERE. BUT WITH THIS BOUNDARY HANGING AROUND...SOMETHING
COULD CROP UP JUST ABOUT ANYTIME. RUC ACTUALLY SHOWS BOUNDARY MOVING
JUST OFFSHORE DURING THE NIGHT...WHICH WOULD PLAY HAVOC WITH
TEMPERATURE AND WIND FORECAST. FOR NOW...THINK WILL HOLD OFF ON
MAKING ANY SIGNIFICANT CHANGES...EXCEPT FOR UPPING MINIMUMS.

CWF...NOTHING MUCH HAPPENING AT BOY020...HOWEVER IF FRONT DOES MOVE
EAST AND/OR SOUTH OVERNIGHT...COULD SEE WINDS BUMP UP QUICKLY.
CANNOT SEE WHERE I CAN DO MUCH FOR NOW THO GIVEN UNCERTAINTY OF
MOVEMENT OF BOUNDARY.

TEXAS LYING IN THE COOL AIR.  WITH TEMPERATURES IN THE 50S AND
WIDESPREAD LIGHT TO MODERATE RAIN...A DAMP AND COOL EVENING LIES

CAUTION IS ADVISED AT LOW  WATER CROSSINGS OR OTHER LOW LYING
AREAS...WHERE SOME FLOODING COULD DEVELOP.

AVERAGE RAIN AMOUNTS OF ONE HALF TO 2 INCHES IS POSSIBLE...AND SOME
ISOLATED AREAS...WERE HEAVY RAIN ORGANIZES WELL...MAY RECEAIVE 2 TO
4 INCHES OF RAIN.  AS A RESULT...FLOODING IS STILL POSSIBLE THROUGH
TONIGHT.

A FLASH FLOOD WATCH MEANS FLOODING IS POSSIBLE WITHIN THE
WATCH AREA.  HEAVY RAIN MAY CAUSE THE RAPID RISE OF STREAMS
AND RIVERS...FLOODING LOW LYING AREAS AND LOW WATER CROSSINGS.
OVER FLATTER TERRAIN THE RAINS MAY CAUSE PONDING WHICH MAY
FLOOD LOW LYING AREAS AND LOW ROADWAYS.

PERSONS IN OR NEAR THE WATCH AREA ARE URGED TO CHECK PREPAREDNESS

CROSS AREAS WHERE WATER COVERS THE ROADWAY!

BE ESPECIALLY CAUTIOUS AT NIGHT WHEN IT IS HARDER TO RECOGNIZE THE
DANGERS OF FLOODS AND FLASH FLOODS. IF FLASH FLOODING IS OBSERVED...
ACT QUICKLY. MOVE UP TO ESCAPE FLOOD WATERS. DO NOT STAY IN AREAS
SUBJECT TO FLOODING WHEN WATER BEGINS RISING. IT IS VERY DIFFICULT
AT NIGHT TO TELL HOW MUCH WATER IS ON ROADS. MOTORISTS SHOULD NOT
DRIVE THROUGH WATER OF UNKNOWN DEPTH.
