AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAKE CHARLES LA
953 PM CDT WED APR 23 2014

.UPDATE...
HIGH PRESSURE OVER THE NORTHERN GULF IS ALLOWING FOR MOISTURE TO
MOVE INLAND OVER SOUTHEAST TEXAS AND SOUTHERN LOUISIANA THIS
EVENING. ANOTHER BEAUTIFUL DAY TODAY SAW TEMPERATURES CLIMB INTO
THE 80S UNDER SUNNY SKIES AFTER THE FOG BURNED OFF THIS MORNING.
THE FRONT THAT WAS TO OUR SOUTH HAS MOVED BACK NORTHWARD AND
EXTENDS FROM SOUTHEAST OKLAHOMA INTO SOUTH-CENTRAL MISSISSIPPI
THIS EVENING.

MODELS ARE HINTING AT MORE FOG ON TAP TONIGHT WITH SOME AREAS
FALLING BELOW ONE MILE TOWARDS SUNRISE. TEMPS EXPECTED TO RANGE
FROM THE MID TO UPPER 60S AT THE COAST TO NEAR 60 ACROSS THE LAKES
REGION OF SOUTHWEST TEXAS AND CENTRAL LOUISIANA. ANOTHER FRONT
LOOKS TO APPROACH FROM THE NORTHWEST BY EARLY FRIDAY MORNING
BEFORE STALLING OVER THE COASTAL WATERS. NOT LOOKING FOR ANY REAL
CHANCE AT PRECIP AND TEMPS WILL NOT SHOW MUCH VARIATION...BUT
DRIER AIR WILL SET IN FOR FRIDAY. THE HIGH PRESSURE WILL MOVE
QUICKLY OFF TO THE EAST WITH RETURN FLOW ON SATURDAY MORNING.
RETURN MOISTURE WILL MOVE UP FROM DEEP SOUTH TEXAS AND INTO
EASTERN TEXAS BY EARLY SUNDAY MORNING. THIS WILL ESTABLISH A
DEEPER MOISTURE PROFILE WITH THE CHANCE FOR SOME SHOWERS SUNDAY
AFTERNOON/EVENING TIME-FRAME. CHANCES FOR SHOWERS AND
THUNDERSTORMS WILL CONTINUE INTO MONDAY AS ANOTHER FRONT THIS TIME
STRONGER WILL PUSH THROUGH THE REGION. TEMPERATURES WILL COOL ON
TUESDAY WITH WEDNESDAY MORNING SEEING TEMPS STARING OUT IN THE LOW
50S CENTRAL LOUISIANA WITH MID 50S DOWN ALONG THE I-10 CORRIDOR.
