.DISCUSSION...
CURRENT SYNOPTIC SET UP ACROSS THE U.S. IS ONE OF SHALLOW UPPER
TROUGHING OVER THE GREAT BASIN WITH AMPLIFIED RIDGING ACROSS THE
EASTERN THIRD OF THE COUNTRY. AT THE SURFACE...DEEP WESTERN PLAINS
PRESSURES (AS LOW AS 988 MB)...IN RELATION TO U.S. SOUTHEASTERN
HIGH PRESSURE...HAS CREATED A SUPER TIGHT INLAND PRESSURE GRADIENT.
TRANSLATION IS FOR ANOTHER DAY (OR TWO) OF PRIMARILY AFTERNOON
SUSTAINED WINDS RANGING AROUND 15-25 KNOTS...GUSTING TO NEAR 30
KNOTS. THUS...THE MAIN SHORT TERM STORY WILL BE LATE MORNING
THROUGH AFTERNOON HIGH WIND. A WIND ADVISORY WILL BE IN EFFECT
FOR COUNTIES ALONG AND WEST OF THE I-45 CORRIDOR FROM 16-00Z.

LITTLE CHANGE IN DAY-TO-DAY WEATHER FOR THE REMAINDER OF THE MONTH.
PARTIALLY CLOUDY MORNINGS WILL SCATTER OUT TO MID-DAY CUMULUS OR
MOSTLY SUNNY AS MORNING MINIMUM TEMPERATURES IN THE MEAN LOWER 70S
GRADUALLY WARM INTO THE AVERAGE INTERIOR LOWER 90S (COASTAL MIDDLE
80S) BY 19-20Z. AS WINDS DIE DOWN THROUGH THE HOLIDAY WEEKEND...WITH
SIMILAR 85H UPPER TEEN-LOWER 20C TEMPS AND THICKNESS VALUES IN THE
UPPER 570'S...DIURNAL MAX TEMPS MAY COME IN A DEGREE OR TWO HIGHER
THAN IN PREVIOUS DAYS. ALTHOUGH OVERALL MOISTURE WILL REMAIN WELL
BELOW NORMAL THROUGH THE PERIOD (1-1.25 INCH PWAT IS UNDER THE 25
PERCENTILE CURVE)...LOWER LEVEL MOISTURE TRAPPED UNDER WARMING
MID-LEVELS OVER SUBSEQUENT DAYS OF SUBSIDENCE (FROM THE EXPANSION
OF A MONSTER RIDGE CENTERED OVER THE LOWER MS VALLEY) WILL MAKE
FOR MORE OPPRESSIVE HEAT AND HUMIDITY. A LONG DURATION ONSHORE
FETCH WILL KEEP DEW POINTS PUMPED UP INTO THE AVERAGE UPPER 60S TO
LOWER 70S...MIXING OUT TO THE LOW-MID 60S NORTH OF CITY. VERY LOW
(TO NIL) RAIN CHANCES THROUGH THE MEMORIAL DAY WEEKEND. AS MENTIONED
IN EARLIER AFDS...THERE WILL BE A SLIGHT INCREASE IN EARLY WEEK
POPS PER MINUTE LOWERING OF THE HEIGHT FIELD (RELATIVELY WEAKER
RIDGING)...ALONG WITH EARLY DAY SEA-TO-LAND SPEED SHEAR WITHIN A
HIGHLY-MOIST AND HEATED LOWER 4K FT LAYER. 31

&&

.MARINE...
MODERATE TO STRONG ONSHORE FLOW WILL PERSIST TODAY AND TONIGHT AND
POSTED SCA'S ACROSS ALL THE WATERS WITH A TIGHT PRES GRADIENT IN
PLACE. HIGHER SEAS OFF THE COAST WILL PRODUCE LARGER THAN NORMAL
SURF ALONG AREA BEACHES TODAY AND FRIDAY...WHICH SHOULD PROBABLY BE
NOTED FOR ANY EARLY HOLIDAY WEEKEND BEACH GOERS (HIGHER SURF
TYPICALLY COINCIDES WITH HIGHER RISK OF RIP CURRENTS ESP NEAR PIERS
AND JETTIES). WINDS/SEAS WILL GRADUALLY SUBSIDE OVER THE WEEKEND AND
INTO EARLY NEXT WEEK AS THE GRADIENT RELAXES. 47

&&

.AVIATION...
MVFR CIGS ACROSS THE NW 1/3 TO 1/2 OF SE TX SHOULD LIFT INTO VFR
TERRITORY BY MID TO LATE MORNING. SRLY WINDS WILL BECOME GUSTY
DURING THAT TIME FRAME AS WELL WITH SOME GUSTS ABOVE 25KT A FAIRLY
DECENT BET WEST OF I-45 THIS AFTN. EXPECT MVFR CIGS TO FILL BACK IN
OVERNIGHT AND MAY EXTEND A BIT CLOSER TO THE METRO TERMINALS.  47
