.DISCUSSION...
THE UPPER LEVEL LOW PRESSURE AREA OVER TEXAS CONTINUES TO SINK
SOUTHWARD THIS AFTERNOON WITH A NICE CIRCULATION SEEN ON SATELLITE
IMAGERY. THIS IS HELPING TO DRAW MOISTURE UP FROM THE SOUTHERN
GULF...RESULTING IN SOME SHOWERS IN THE COASTAL WATERS AND NEAR
COAST INLAND AREAS. THIS INLAND ACTIVITY SHOULD BE EXTREMELY LIGHT
IN NATURE AS IT IS ENCOUNTERING A PRETTY DRY AIRMASS. THIS ACTIVITY
WILL CONTINUE IN ADVANCE OF THE UPPER LOW WHICH IS FORECAST TO
WEAKEN AND BEGIN MOVING EASTWARD TONIGHT. ANY ACTIVITY THAT
LINGERS INTO THE DAYTIME HOURS TOMORROW SHOULD REMAIN OVER THE
GULF AS THE TROUGH MOVES OVERHEAD.
THE BEGINNING AND MIDDLE PART OF THE WEEK WILL BE DRY AS NO
SIGNIFICANT WEATHER FEATURES ARE SET TO AFFECT THE AREA. HOT AND
HUMID CONDITIONS RETURN AS SOUTHERLY FLOW PERSISTS. A COLD FRONT
SINKS SOUTHWARD TOWARD THE SOUTHEAST BUT REMAINS WELL NORTH OF OUR
AREA. A MID LEVEL RIDGE AMPLIFIES ACROSS THE MID SECTION OF THE
COUNTRY TOWARD THE END OF THE WORK WEEK WHILE THE ATMOSPHERE BECOMES
MOIST ENOUGH AND UNSTABLE ENOUGH TO INTRODUCE A CHANCE OF THUNDER
BACK IN TO THE FORECAST. THIS PATTERN HOLDS INTO NEXT WEEKEND.

CIRRUS AND ALTOSTRATUS OVER THE NEXT 24 HOURS. 24

PERHAPS SOME GUSTINESS TO 25 KNOTS WORKING TO THE SURFACE FROM THE
MORE ORGANIZED CLUSTERS. WINDS AND SEAS WILL OTHERWISE BE RATHER LOW
THROUGH MONDAY BEFORE SOUTHERLY FLOW INCREASES FOR THE MIDDLE TO
LATTER PART OF THE UPCOMING WEEK. 24
