NATIONAL WEATHER SERVICE LAKE CHARLES LA
853 PM CDT SUN APR 20 2014

.UPDATE...A WEAK TROF WILL APPROACH FROM THE WEST TONIGHT,
BRINGING A LIGHT SOUTHERLY FLOW AND SOME MOISTURE NEAR THE SURFACE.
THIS MOISTURE SHOULD BE SUFFICIENT FOR THE FORMATION OF PATCHY
GROUND FOG LATER TNITE...WHICH IS ALREADY IN THE FORECAST. ONLY
CHANGE WAS A TWEAK LOWER ON TEMPS MAINLY AROUND LFT.

AVIATION...
VFR FLIGHT WX THRU THE EVE HOURS WITH FOG DEVELOPING THRU THE
OVERNIGHT HOURS CONTG THRU SR. MID LVL CLOUD SHIELD TO THE WEST
IS EXPECTED TO MOVE IN TWRDS MIDNIGHT.

PREV DISCUSSION... /ISSUED 341 PM CDT SUN APR 20 2014/

DISCUSSION...
A RIDGE AT THE SURFACE AND A LOFT IS MAKING FOR A VERY NICE EASTER
AS FAR AS THE WEATHER GOES WITH WARM AND MILD TEMPERATURES...LOW
RELATIVE HUMIDITY AND PLENTY OF SUNSHINE. ONLY ISSUE OVER THE NEXT
24 HOURS WILL BE THE POSSIBILITY OF SOME PATCHY FOG JUST BEFORE AND
AFTER SUNRISE...AS LIGHT WINDS AND MAINLY CLEAR SKIES MAY BE
ENOUGH TO HELP AIR TEMPERATURES NEAR THE OVERNIGHT DEW POINT
READINGS.

UPPER LEVEL RIDGING WILL BREAK DOWN ENOUGH ON LATE MONDAY INTO
TUESDAY THAT A WEAK PACIFIC COLD FRONT WILL MOVE DOWN INTO THE
REGION AND STALL NEAR I-10...AS UPPER LEVEL SUPPORT MOVES OFF TO
THE NORTHEAST. ENOUGH LIFT AND MOISTURE AROUND TO ALLOW FOR A
SLIGHT CHANCE AND LOW END CHANCE POPS WITH THIS FEATURE.
HOWEVER...TEMPERATURES FOR THE MOST PART WILL NOT BE AFFECTED.

SOUTHERLY WINDS WILL RETURN ON WEDNESDAY AND PERSIST THROUGH THE
REMAINDER OF THE WEEK AS HIGH PRESSURE WILL BE LOCATED EAST OF THE
REGION...AND LOW PRESSURE WILL FORM OVER THE SOUTHERN PLAINS.
THESE SOUTHERLY WINDS WILL HELP BRING WARM OVERNIGHT LOWS WITH
NEAR SEASONAL SPRING DAYTIME HIGHS. BY THE END OF THE WEEK...UPPER
LEVEL RIDGING AGAIN BREAKS DOWN WITH A MORE ACTIVE SOUTHWEST FLOW
ALOFT. THE SOUTHWEST FLOW ALOFT WILL BRING ACROSS A SERIES OF
DISTURBANCES THAT MAY BRING ABOUT A SMALL CHANCE FOR SHOWERS AND
STORMS INTO THE WEEKEND.

RUA

MARINE...
SURFACE RIDGE WILL HOLD OVER THE COASTAL WATERS THROUGH MONDAY.
THIS WILL KEEP LIGHT WINDS AND LOW SEAS IN PLACE. A WEAK FRONT
WILL STALL NORTH OF THE COASTAL WATERS ON TUESDAY. A FEW SHOWERS
AND STORMS MAY DEVELOP WITH THIS SYSTEM. HOWEVER...WINDS AND SEAS
SHOULD REMAIN LIGHT. AN INCREASE IN ONSHORE FLOW AND SOME INCREASE
IN SEAS WILL TAKE PLACE BY THE MIDDLE TO LATTER PART OF THE WEEK
AS LOW PRESSURE DEVELOPS IN THE SOUTHERN PLAINS AND INCREASES THE
PRESSURE GRADIENT OVER THE NORTHWEST GULF OF MEXICO.
