AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SHREVEPORT LA
456 AM CDT FRI APR 19 2013

.DISCUSSION...
A 1024MB HIGH IS OVER FAR NORTH TEXAS WITH NORTHWEST WINDS ACROSS
THE SOUTHERN PLAINS AND LOWER MISS VALLEY. WE HAVE LOADED IN THE
NAM WINDS FOR TODAY AND MAY OCCASIONALLY BE CLOSE TO LAKE WIND
CRITERIA...BUT THIS APPEARS TO BE FAIRLY LOCALIZED. THE COLD FRONT
IS ALL BUT ACROSS LA WITH STATIONS FAR DOWN RIVER STILL SW. THE
COLD FRONT EXTENDS ALONG THE GULF COAST AND TURNS UP TO NEAR
MOBILE AND HAS YET TO CROSS MUCH OF EASTERN AL. AS FAR AS OUR
AREA...LOTS OF CLOUDS AND A STUBBORN CAP KEPT THE SEVERE WEATHER
IN CHECK. ONE LSR IN UNION CO AND RAINFALL TOTALS GENERALLY FROM
A HALF INCH TO INCH AND SOME BETTER THAN AN INCH.

OUR CURRENT TEMPERATURES ARE IN UPPER 30S NORTH OF I-30 AND AT
LONGVIEW WITH LOTS OF LOWER 40S ELSEWHERE. THE WARMEST READINGS
ARE IN MONROE AND LUFKIN WHICH WERE BOTH AT 45 LAST HOUR. WE WILL
SOON BOTTOM OUT BETTER THAN 10 DEGREES BELOW AVERAGE AND AS THE
HIGH PRESSURE SYSTEM MOVES IN TODAY...WITH LIGHT WINDS AND EVEN
LOWER DEW POINTS...THIS TIME TOMORROW MAY BE CLOSE TO ANOTHER 10
DEGREES COLDER. EXPECT SOME LIGHT FROST (PROTECT TENDER VEGES) AND
PERHAPS SOME PATCHY FOG WILL BE POSSIBLE AS A LIGHT SOUTHERLY WIND
LIFTS IN BEHIND THE EXITING HIGH PRESSURE. A GOOD DAY OF DRYING
SHOULD LIMIT DENSE FOG. DESPITE THE ABUNDANT SUNSHINE TODAY...HIGHS
TODAY WILL BE CHILLY FOR MID APRIL WITH THE COLD AIR ADVECTION
CONTINUING...BUT A SHIFT IN THE WINDS WILL REBOUND SATURDAY
AFTERNOON/S READINGS BACK TO AROUND ROOM TEMPERATURE.

SKIES ARE CLEARING WITH STILL SOME LOW CLOUDS STILL DRAPED OVER
THE WARMER READINGS FROM LUFKIN TO MONROE. THE RETURN FLOW OFF THE
GULF WILL FEED INTO OUR NEXT SYSTEM EARLY IN THE NEW WORK WEEK
WITH SHOWERS AND THUNDERSTORMS BACK IN OVER THE AREA FOR TUESDAY
THEN CLEARING OVERNIGHT FOR THE MOST PART. HIGH PRESSURE WILL
AGAIN KEEP THE MERCURY BELOW AVERAGE THROUGH MID WEEK. MAV/MEX
NUMBERS ARE REASONABLE ACROSS THE BOARD AND HAVE BEEN BLENDED INTO
THE FORECAST. /24/

&&

.AVIATION...
VFR FLIGHT CATEGORIES...WITH MOSTLY CLEAR SKIES OR HIGH THIN
CIRRUS...WILL PREVAIL ACROSS THE FOUR STATE REGION THROUGH THE END
OF THE TERMINAL FORECAST PERIOD ENDING AT 20/12 UTC. A TIGHT
PRESSURE GRADIENT BETWEEN SURFACE HIGH PRESSURE OVER NORTH TEXAS AND
SURFACE LOW PRESSURE OVER THE GREAT LAKES REGION...WILL RESULT IN
NORTHWEST WINDS OF 10 TO 15 KNOTS WITH OCCASIONAL HIGHER GUSTS TO 20
TO 25 KNOTS FROM AROUND 19/14 UTC TO 19/23 UTC FOR SOME PARTS OF
EAST AND NORTHEAST TEXAS INTO SOUTH ARKANSAS AND NORTH LOUISIANA. AS
THE SURFACE HIGH SHIFTS EAST INTO EAST AND NORTHEAST TEXAS DURING
THE LATE AFTERNOON...THE PRESSURE GRADIENT RELAXES AND WINDS BECOME
LIGHT AND VARIABLE AFTER 20/00 UTC. /06/
