.DISCUSSION...
SKIES ARE SUNNY ACROSS ALL OF SOUTHEAST TEXAS EARLY THIS AFTERNOON WITH
SURFACE HIGH PRESSURE CENTERED OFF TO OUR NORTHWEST. HIGH TEMPERATURES
SO FAR TODAY ARE IN THE LOWER TO MID 70S...SOME 5 TO 10 DEGREES BELOW
NORMAL FOR EARLY MAY. A SHORTWAVE CURRENTLY IN THE VICINITY OF THE TX/OK
PANHANDLE WILL MOVE ACROSS OUR AREA OVERNIGHT AND EARLY TOMORROW MORNING
AND WILL ONLY GIVE PARTS OF OUR AREA SOME CLOUDS. THE CURRENT WESTERN
FLOW ALOFT SHIFTS TO THE NORTHWEST BEHIND TONIGHT`S SHORTWAVE...AND
THIS UPPER LEVEL FLOW PERSISTS THROUGH THE END OF THE WEEK AS RIDGING
MOVES VERY SLOWLY EASTWARD ACROSS THE STATE. AT THE SURFACE...HIGH PRESSURE
STAYS IN CONTROL OF THE AREA AS IT TOO WORKS VERY SLOWLY EASTWARD ACROSS
THE STATE RESULTING IN A CONTINUATION OF COOL NIGHTS AND MILD/WARM DAYS.
A PATTERN CHANGE IS STILL ON SCHEDULE TO BEGIN OVER THE WEEKEND AS THE
SURFACE HIGH MOVES OFF TO THE EAST AND THE UPPER FLOW SWINGS BACK AROUND
TO THE SOUTHWEST. LOOK FOR GRADUALLY WARMING TEMPERATURES (ESPECIALLY
OVERNIGHT LOWS) AND GRADUALLY INCREASING CLOUDS IN RESPONSE TO STRENGTHENING
ONSHORE WINDS. THE FORECAST HAS VERY LOW RAIN CHANCES IN OUR FAR WEST
AND FAR NORTHWEST COUNTIES BEGINNING SUNDAY AFTERNOON FOLLOWED BY INCREASING
RAIN CHANCES AREAWIDE (HIGHEST NORTHWEST AND LOWEST SOUTHEAST AND OFF
THE COAST) FOR THE FIRST HALF OF NEXT WEEK AS DISTURBANCES RIDE ALONG
THE SOUTHWEST FLOW ALOFT.  42

.MARINE...
CENTRAL UNITED STATES HIGH PRESSURE EXPANDING DOWN INTO THE WESTERN
GULF WILL MAINTAIN A LIGHT OFFSHORE WIND OVER THE NEXT FEW DAYS. THE
EASTERN MOVEMENT OF THIS HIGH INTO THE EASTERN THIRD OF THE COUNTRY
WILL INITIATE A RETURN FLOW ON FRIDAY. LOWERING PRESSURES IN THE LEE
OF THE ROCKIES OVER THE WEEKEND WILL STRENGTHEN ONSHORE WINDS TO
POSSIBLE CAUTION LEVELS BY SUNDAY. THE LOCAL BAY AND NEARSHORE SEA
STATE WILL GENERALLY BE CALM...SLIGHTLY MORE CHOPPY DURING THE
AFTERNOON HOURS. THROUGH THE WORK WEEK...AVERAGE SEA HEIGHTS WILL
RANGE IN THE 1 TO 3 FOOT RANGE. 31
