DISCUSSION...
QUIET SOUTHEAST TEXAS WEATHER WILL CONTINUE FOR THE NEXT SEVERAL DAYS.
THE STORM SYSTEM ORGANIZING TODAY IN/AROUND THE MISSOURI/ILLINOIS BORDER
(AND EVENTUALLY BECOMING A BIG TIME NORTHEASTERN U.S. SNOW STORM) WILL
DRAG A WEAK FRONTAL BOUNDARY ACROSS OUR AREA TODAY AND WILL SHIFT THE
WINDS TO THE WEST-NORTHWEST AND NORTHWEST. IT COULD GET A LITTLE ON
THE BREEZY SIDE BEHIND THE BOUNDARY. NO SIGNIFICANT COOLING IS ANTICIPATED
BEHIND THIS BOUNDARY...AND TEMPERATURES WILL ACTUALLY BE GRADUALLY WARMING
AS WE HEAD ON INTO TUESDAY AND WEDNESDAY. WINDS WILL COME BACK AROUND
TO THE SOUTH ON WEDNESDAY...BUT THIS ONSHORE FLOW WILL NOT LAST VERY
LONG AS OUR NEXT COLD FRONT MOVES THROUGH ON THURSDAY. THERE WILL BE
COOLER TEMPERATURES BEHIND THIS FRONT AS HIGH PRESSURE BUILDS INTO THE
AREA. NEXT WEEKEND...OUR EYES WILL TURN TOWARD THE SLOWLY ORGANIZING
MID/UPPER LEVEL LOW OUT WEST OFF THE BAJA PENINSULA. UNCERTAINTIES
EXIST WITH THE EVOLUTION AND PROGRESS OF THIS SYSTEM...SO FOR NOW
WILL CONTINUE TO INDICATE A COOL AND CLOUDY TO MOSTLY CLOUDY WEEKEND
WITH GRADUALLY INCREASING RAIN CHANCES.  42

MARINE...
TODAY`S GULF WESTERLIES WILL STRENGTHEN TO SCEC LEVELS FURTHER
OFFSHORE AS THE PRESSURE GRADIENT TIGHTENS BETWEEN A WESTERN TEXAS
HIGH AND A MIDWESTERN LOW PRESSURE SYSTEM. THE EVENING PASSAGE OF A
DRY COLD FRONT WILL MAINTAIN MODERATE WINDS WHILE VEERING WESTERLIES
MORE NORTHERLY THROUGH MONDAY MORNING. RESPONDING GULF SEA HEIGHTS
WILL INCREASE BY AN AVERAGE FOOT OR SO THROUGH MONDAY. EARLY WEEK
NORTH TO WEST BREEZES WILL TURN ONSHORE BY MID-WEEK AS A HIGH
PRESSURE CELL ADVANCES EASTWARD ACROSS THE GULF. ANOTHER DRY COLD
FRONTAL PASSAGE LATE THURSDAY NIGHT INTO FRIDAY MORNING WILL VEER
WINDS AROUND TO NORTHEAST TO CLOSE OUT THE WORK WEEK. 31
