AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAKE CHARLES LA
436 AM CDT WED APR 23 2014

.DISCUSSION...
A DENSE FOG ADVISORY WILL REMAIN IN EFFECT THROUGH THE MORNING AS
PATCHY RADIATIONAL FOG IS FORMING ACROSS SETX AND SWLA. SEVERAL
SITES HAVE ALREADY DROPPED TO BELOW ONE QUARTER MILE IN
VISIBILITY. EXPECT BY 9AM SUNRISE WILL CAUSE THE FOG TO DISSIPATE.
AS THE UPPER LEVEL RIDGE BEGINS TO MOVE IN TODAY WINDS WILL BEGIN
TO SHIFT AROUND FROM NORTH TO SOUTH BY THIS AFTERNOON LEADING TO
MODERATE ONSHORE RETURN FLOW. THE HIGH PRESSURE SHOULD STAY IN
PLACE UNTIL THE WEEKEND. AN UPPER LEVEL DISTURBANCE WILL MOVE
INTO THE PLAINS TOMORROW BUT SHOULD STALL OUT TO THE NORTH OF THE
FORECAST AREA. THIS HIGH PRESSURE WILL ALLOW FOR OUR TEMPS TO STAY
A FEW DEGREES ABOVE NORMAL THROUGH THE WEEKEND.

BEST CHANCE FOR RAIN IN THE FORECAST WILL BE IN THE EXTENDED.
MODELS ARE IN AGREEMENT THAT A STRONG LOW PRESSURE SYSTEM WILL
DEVELOP OVER THE ROCKIES OVER THE WEEKEND AND MOVE ACROSS THE
CENTRAL PLAINS SOME TIME EARLY NEXT WEEK. THE ASSOCIATED COLD
FRONT LOOKS TO BE QUITE STRONG AND WILL BRING A DECENT CHANCE FOR
SHOWERS ALONG WITH QUITE COOL TEMPERATURES. HOWEVER TIMING OF THE
SYSTEM STILL REMAINS INEXACT. THE ECMWF BRINGS THE FRONT IN MONDAY AND
PUSHES THROUGH MONDAY EVENING WHEREAS THE GFS IS ABOUT 12 HOURS
SLOWER AND DOESN`T CLEAR THE FRONT THROUGH THE FORECAST AREA UNTIL
TUESDAY MORNING. EITHER WAY EXPECT MUCH COOLER MIN TEMPS TUESDAY
EVENING BEHIND THE FRONT.
