DISCUSSION...
LOCAL 12Z SOUNDING SHOWED JUST A NARROW SATURATIOIN LAYER AROUND
H8...OTHERWISE DRY CONDITIONS WERE NOTED THROUGH THE COLUMN THANKS
TO A BUILDING RIDGE ALOFT. GUESS A STRAY SHOWER OR TWO CANNOT BE
RULED OUT WITH THAT LIMITED MOISTURE AND A DEVELOPING AFTERNOON
SEA BREEZE...BUT DO NOT SEE ENOUGH DEVELOPMENT TO WARRANT CHANGING
OUR CURRENT POP-FREE FORECAST. ELSEWHERE TWEAKS WERE MINOR AT MOST

FOR THE 12Z TAF PACKAGE.

AVIATION...
VFR IS EXPECTED TO PREVAIL. DRY AIR WILL CONTINUE TO LIMIT CLOUD
COVER AND CONVECTION...WITH HIGH PRESSURE AT THE SFC RESULTING IN
LIGHT AND VARIABLE WINDS. AN ISOLATED -SHRA/TSRA OR TWO ALONG THE
SEA BREEZE IS POSSIBLE...ESPECIALLY ACROSS SOUTH CENTRAL LA...BUT
COVERAGE/PROBABILITY TOO LOW TO MENTION AT ACADIANA TERMINALS.

PREV DISCUSSION... /ISSUED 351 AM CDT TUE JUN 2 2015/

DISCUSSION...
BEAUTIFUL MORNING ACROSS THE REGION AS A WEAK FRONTAL
BOUNDARY SETTLED ACROSS THE COASTAL AREAS OF LOUISIANA AND
SOUTHEAST TEXAS. DRIER AIR CONTINUED TO FILTER SOUTHWARD
OVERNIGHT WITH MID TO UPPER 60S DEWPOINT AIR EXTENDING ALL
THE WAY INTO THE MARINE WATERS. TEMPERATURES WERE VERY
COMFORTABLE IN THE UPPER 60S TO NEAR 70.

THE WEAK FRONTAL BOUNDARY SHOULD MEANDER TODAY ALONG THE COAST
BEFORE DISSIPATING ON WEDNESDAY. MEANWHILE...IN THE THE UPPER
LEVELS...OUR REGION WAS SANDWICHED BETWEEN A TROUGH OF LOW
PRESSURE OVER THE EASTERN UNITED STATES AND A RIDGE OF HIGH
PRESSURE ACROSS THE SOUTH CENTRAL UNITED STATES. THIS PATTERN IS
EXPECTED TO CONTINUE ALL WEEK. WHAT A RELIEF IT! WE NEED SOME
SERIOUS DRYING TIME AND LOOKS LIKE WE WILL GET IT.

AS WE MOVE INTO THE WEEKEND...ENOUGH MOISTURE SLOWLY WORKS BACK
INTO THE REGION BY SUNDAY AS THE UPPER LEVEL RIDGE TO OUR WEST
RETROGRADES ALLOWING FOR WEAK DISTURBANCES TO PASS OVER THE AREA
SUNDAY AND AGAIN MONDAY. THE PROBABILITY OF RAIN WILL REMAIN LOW
AND THEREFORE WE ACTUALLY HAVE A GREAT 7 DAY FORECAST PACKAGE ON
HAND. THIS WOULD BE AN EXCELLENT TIME TO CATCH UP ON YARD WORK AND
FIX THAT LEAKY ROOF.

06

MARINE...
HIGH PRESSURE OVER THE GULF WATERS WILL RESULT IN LIGHT WINDS
VARYING BACK AND FORTH FROM NORTHERLY TO SOUTHERLY AND DIRECTIONS IN
BETWEEN. SEAS WILL REMAIN LOW IN THIS WEAK WIND REGIME.
