.PREV DISCUSSION... /ISSUED 337 PM CDT MON SEP 22 2014/

DISCUSSION...A COLD FRONT HAS PUSHED TO AROUND THE I-10 CORRIDOR
THIS AFTERNOON AND A FEW SHOWERS ARE NOTED AHEAD OF THE BOUNDARY.
BEHIND THE FRONT, A COOLER AND DRIER AIRMASS IS FILTERING IN. LOW
TEMPS TUE AND WED MORNINGS WILL BE 5 TO AROUND 10 DEGREES LESS
THAN THIS PAST MORNING`S LOWS WITH AFTERNOON HIGHS MOSTLY IN THE MID
80S. THE FRONTAL BOUNDARY WILL GRADUALLY STALL ACROSS THE NORTHERN
GULF KEEPING SHOWER CHANCES ACROSS THE COASTAL WATERS AND
SOUTHWARD INTO EARLY FRIDAY. BY THE END OF THE WEEK A DISTURBANCE
ALOFT WILL MOVE INTO THE SOUTHERN PLAINS ALLOWING LOW PRESSURE TO
DEVELOP ALONG THE STALLED FRONTAL BOUNDARY IN THE NORTHERN GULF.
THE FRONTAL WAVE IS EXPECTED TO MOVE NORTHEAST INTO THE NORTHERN
GULF COAST DURING THE WEEKEND. THERE ARE UNCERTAINTIES REGARDING
WHERE THIS LOW WILL TRACK AND HOW MUCH PRECIP WILL SPREAD ACROSS
THE CWA. AT THIS TIME HIGHER RAIN CHANCES CAN BE EXPECTED ACROSS
THE SE HALF OF THE CWA WITH LOWER CHANCES TOWARD THE EAST TX LAKE
REGION. THIS WILL ALSO AFFECT THE HIGH TEMP FORECAST FOR THE WEEKEND
AND COULD EASILY PUSH HIGHS DOWN SEVERAL DEGREES IF RAIN CHANCES
BECOME HIGHER WITH THE FRONTAL LOW FARTHER WEST THAN CURRENTLY
INDICATED.

MARINE...A MODERATE OFFSHORE FLOW WILL OCCUR TONIGHT BEHIND A
COLD FRONT. SMALL CRAFT SHOULD EXERCISE CAUTION THROUGH TUESDAY
MORNING IN THE GULF WATERS. A LIGHT TO MODERATE EAST FLOW WILL
THEN CONTINUE THROUGH THE WEEK WITH WINDS POSSIBLE INCREASING
SOMEWHAT AGAIN DURING THE COMING WEEKEND AS LOW PRESSURE FORMS
ALONG THE STALLED FRONTAL BOUNDARY AND MOVES CLOSE TO AREA.
