AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SHREVEPORT LA
1210 AM CDT TUE APR 21 2015

.AVIATION...
FOR THE 21/06Z TAFS...VFR CONDITIONS SHOULD PREVAIL THROUGH THE
TAF PERIOD BUT CLOUD COVERAGE IS EXPECTED TO GRADUALLY INCREASE
AND CIGS SHOULD GRADUALLY LOWER. VERY LIGHT WINDS WILL GRADUALLY
VEER TO THE SOUTHEAST BY SUNRISE BUT SPEEDS SHOULD REMAIN AROUND
10 KTS OR LESS. A FEW ISOLATED SHOWERS COULD DEVELOP AFTER
21/18Z...ESPECIALLY ALONG AND NORTH OF I-20...BUT CHANCES ARE TOO
LOW TO MENTION IN THE TAFS. /09/

.PREV DISCUSSION... /ISSUED 913 PM CDT MON APR 20 2015/

DISCUSSION...
FORECAST FOR THE MOST PART IS PRETTY MUCH ON TRACK. SFC RIDGING
CONTINUES TO EDGE INTO THE REGION FROM THE WEST ALLOWING WINDS TO
DECOUPLE QUICKLY WITH MOST SITES NEAR CALM AS OF 02Z. HOURLY TEMP
GRIDS ARE REALLY CLOSE TO ACTUAL VALUES BUT DEWPOINTS GRIDS ARE A
TAD HIGHER ACROSS OUR SOUTHERN ZONES THAN WHAT WAS FORECAST. ALSO
IR IMAGERY SHOWS THAT HIGH CLOUDS CONTINUE TO STREAM IN FROM THE
WEST.

FOR THE UPDATE...HAVE BEEFED UP CLOUD COVER A LITTLE MORE ALONG
AND SOUTH OF THE I-20 CORRIDOR OVERNIGHT. FEEL LIKE THIS MOISTURE
SHOULD BE THIN ENOUGH NOT TO HAMPER OVERNIGHT TEMPS. HIGH CLOUDS
ACROSS THE OK/TX PNDL ASSOCIATED WITH WEAK DISTURBANCE WILL HEAD
OUR WAY OVERNIGHT AS WELL WITH THIS MOISTURE LIKELY NOT MAKING IT
INTO OUR NORTHERN ZONES UNTIL NEAR OR SHORTLY AFTER SUNRISE.

UPDATED ZONE PACKAGE OUT SHORTLY...13.
