AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SHREVEPORT LA
952 AM CST SAT MAR 18 2006

...NO UPDATE TO THE TEXT FORECAST IS EXPECTED AT THIS TIME...

.DISCUSSION...WATER VAPOR IMAGERY SHOWS THE LONGWAVE TROUGH OFF THE
WEST COAST HAS SLAMMED ASHORE...AND IS TRYING TO WORK ITS WAY EAST.
A SERIES OF WEAKER SHORTWAVE TROUGHS CONTINUES TO MOVE ACROSS OUR
AREA AHEAD OF THIS SYSTEM.  THESE FEATURES ARE COMBINING WITH
ISENTROPIC UPGLIDE AND LOWER CONDENSATION PRESSURE DEFICITS TO
PRODUCE RAIN OVER THE FOUR STATE REGION THIS MORNING.  THERE IS A
LITTLE BIT OF ELEVATED INSTABILITY PRESENT...BUT MOST OF THAT
REMAINS OVER NORTH TEXAS.  THE FRONT IS NOT PROGRESSING NORTHWARD AS
FAST AS I EXPECTED YESTERDAY.  SURFACE OBSERVATIONS INDICATE THE
BOUNDARY IS DRAPED ACROSS SOUTH-CENTRAL TEXAS AT MID-MORNING.

THE RAIN HAS CONTINUED OVER AREAS ALONG AND NORTH OF INTERSTATE 20
FOR MUCH OF THE MORNING...WITH A BREAK IN THE RAIN NOTED IN MANY
OTHER PLACES.  HOWEVER...IT LOOKS LIKE ROUND TWO IS ON THE WAY.
EAST TEXAS AND CENTRAL LOUISIANA MAY SEE RAIN BEFORE NOON...WITH
MOST PLACES IN SHREVEPORT-BOSSIER CITY NOT SEEING RAIN UNTIL ABOUT
NOONTIME.

BOTH THE GRIDDED AND TEXT FORECASTS APPEAR TO BE REFLECTIVE OF THE
ONGOING AND FORECAST WEATHER CONDITIONS.  AS SUCH...I DO NOT FEEL AN
UPDATE IS NEEDED AT THIS TIME.

TEXAS...SOUTHWEST ARKANSAS...NORTHWEST...AND NORTH CENTRAL LOUISIANA.

NO HAZARDOUS WEATHER IS EXPECTED AT THIS TIME.

A SERIES OF DISTURBANCES WILL CONTINUE TO BRING WIDESPREAD RAIN...
ALONG WITH SCATTERED THUNDERSTORMS...TO THE FOUR STATE REGION
THROUGH TONIGHT.  ANY OF THE THUNDERSTORMS COULD PRODUCE OCCASIONAL
CLOUD TO GROUND LIGHTNING AND WIND GUSTS TO 30 MILES AN HOUR.

THERE IS A RISK OF SEVERE THUNDERSTORMS MONDAY OVER THE FOUR STATE
REGION.  DAMAGING WINDS IN EXCESS OF 60 MILES AN HOUR AND HAIL

FORECAST TO MOVE INTO THE PLAINS MONDAY...PUSHING A COLD FRONT
INTO OUR REGION...AND RESULT IN THE DEVELOPMENT OF A LINE OF
THUNDERSTORMS.  WITH AMPLE INSTABILITY AND JET STREAM DYNAMICS...SOME
OF THE THUNDERSTORMS COULD BE SEVERE.

.SPOTTER INFORMATION STATEMENT...
ACTIVATION OF EMERGENCY MANAGERS...SKYWARN NETWORKS...AND STORM
SPOTTERS...SHOULD NOT BE NEEDED TODAY OR TONIGHT.
