AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAKE CHARLES LA
1209 PM CDT TUE MAR 22 2016

.AVIATION...SCATTERED TO BROKEN STRATOCU WITHIN VFR CAN BE
EXPECTED TODAY. WINDS WILL REMAIN SOUTHERLY AND GUSTY BETWEEN
HIGH PRESSURE RIDGING ACROSS THE SOUTHEAST CONUS...AND LOW
PRESSURE DEEPENING OVER THE PLAINS. WINDS WILL DIMINISH THIS
EVENING...WHILE STRATOCU WILL SLIP DOWN TO WITHIN MVFR.

&&

.PREV DISCUSSION... /ISSUED 957 AM CDT TUE MAR 22 2016/

UPDATE...
NO SIGNIFICANT CHANGES TO THE GRIDS AT THIS TIME. SOUTHERLY WINDS
WILL BE BREEZY TODAY AS LOW FORMS EAST OF THE ROCKIES. THE
SOUTHERLY WINDS WILL HELP BRING IN LOW LEVEL MOISTURE AND
SCATTERED TO BROKEN CLOUDS UNDER THE CAP.

RUA

PREV DISCUSSION... /ISSUED 658 AM CDT TUE MAR 22 2016/

DISCUSSION...
FOR 12Z TAF ISSUANCE.

AVIATION...
SATELLITE IMAGERY/SFC OBS INDICATE STRATOCU BEGINNING TO MOVE IN
FROM THE GULF...PRIMARILY ACROSS THE SWRN SITES ATTM...AND EXPECT
THIS TO TREND TO CONTINUE ACROSS THE REMAINDER OF THE AREA WITH
SRLY FLOW IN PLACE. SPEAKING OF WHICH A TIGHTENING GRADIENT IS
PROGGED AS HIGH PRESSURE MOVES FARTHER EAST AND IS REPLACED BY LOW
PRESSURE OVER THE PLAINS...AND WIND SPEEDS EXCEEDING 10 KNOTS IS
EXPECTED THROUGH THE AFTERNOON AT ALL SITES. WITH LOW-LEVEL
MOISTURE CONTINUING TO INCREASE EXPECT MVFR CEILINGS TO DEVELOP
AFTER SUNSET...LINGERING THROUGH TONIGHT.

25

PREV DISCUSSION... /ISSUED 317 AM CDT TUE MAR 22 2016/

DISCUSSION...HIGH PRESSURE HAS SHIFTED EAST OF THE AREA OVER THE
PAST SEVERAL HOURS AND IS NOW LOCATED OVER THE NORTH CENTRAL GULF
SOUTH OF THE MISSISSIPPI DELTA. WITH THE RIDGE CENTERED EAST OF
THE AREA WINDS HAVE BECOME SOUTHERLY ALBEIT VERY LIGHT. THIS HAS
ALLOWED TEMPERATURES TO REMAIN SEVERAL DEGREES HIGHER THAN 24 HRS
AGO AND WILL SERVE TO INCREASE TEMPS AND MOISTURE THROUGH THE
NEXT FEW DAYS.

AN UPPER DISTURBANCE OVER THE WESTERN STATES WILL CONTINUE MOVING
EAST TODAY AND WEDNESDAY. LOW PRESSURE WILL DEVELOP IN THE CENTRAL
PLAINS AHEAD OF THE DISTURBANCE AND SERVE TO TIGHTEN THE PRESSURE
GRADIENT LOCALLY INCREASING THE SOUTH FLOW. THIS WILL HELP TO INCREASE
MOISTURE AND TEMPS AHEAD OF THE NEXT FRONT THAT WILL ARRIVE LATE
WED INTO THU. WHILE THE BEST DYNAMICS LOOK TO REMAIN NORTH OF THE
REGION A FEW STORMS MAY BECOME STRONG. INSTABILITY LOOKS MODEST
AT BEST AS DOES THE LLJ, HOWEVER WITH A FAVORABLE JET POSITION AND
PWATS RUNNING 1.25 TO 1.5 SCATTERED TO NUMEROUS STORMS CAN BE
EXPECTED.

BEHIND THE FRONT COOLER TEMPS WILL RETURN WITH TEMPS RUNNING
SLIGHTLY BELOW CLIMO AVERAGES. DRY WX WILL PERSIST THROUGH
FRIDAY, HOWEVER ANOTHER COLD FRONT CAN BE EXPECTED DURING THE
WEEKEND THAT WILL PRODUCE ANOTHER CHANCE FOR RAIN AND
THUNDERSTORMS.

MARINE...THE GRADIENT WILL TIGHTEN TODAY AS HIGH PRESSURE MOVES
AWAY TO THE EAST AND LOW PRESSURE DEVELOPS OVER THE PLAINS. A
SMALL CRAFT ADVISORY WILL BE NEEDED TONIGHT FOR PORTIONS OF THE
COASTAL WATERS. WINDS WILL REMAIN ELEVATED INTO WEDNESDAY AHEAD OF
A COLD FRONT. THE FRONT WILL MOVE THROUGH THURSDAY WITH MODERATE
TO STRONG NORTH WINDS BEHIND THE BOUNDARY AS HIGH PRESSURE BUILDS
IN.
