Hail in Louisiana, May 8, 2006

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SHREVEPORT LA
522 PM CDT MON MAY 8 2006

.DISCUSSION...

QUICK UPDATE TO ADD SEVERE THUNDERSTORM WATCH 308 FOR ALL OF
NORTHERN LOUISIANA UNTIL 11 PM. MOST OF THE THREAT WILL BE ACROSS
NORTH CENTRAL/NORTHEAST LOUISIANA OVER THE NEXT COUPLE OF HOURS.
HOWEVER...SOME ISOLATED CONVECTION IS TRYING TO FORM ALONG THE
OUTFLOW BOUNDARY ACROSS NORTHWEST LOUISIANA AND ADJACENT AREAS OF
EAST TEXAS. STORMS SHOULD HAVE A HARDER TIME MAINTAINING THEM...AS
AREA OF SUBSIDENCE SHOULD BE OVERSPREADING THE AREA IN WAKE OF
WEAK SHORTWAVE CAUSING THE CONVECTION ACROSS NORTH CENTRAL
LOUISIANA.

UPDATE ALREADY OUT.

.PREV DISCUSSION... (ISSUED 259 PM CDT MON MAY 8 2006)

DISCUSSION...

WATER VAPOR IMAGERY SHOWS A SOUTHERN STREAM TROUGH OVER SE OF
BAJA...W/MORE OR LESS ZONAL FLOW OVER THE CENTRAL CONUS.  CLOSER TO
HOME...A STATIONARY FRONT BORDERS THE SOUTHERN ZONES UNDER A
CAP...WHILE A SHORTWAVE HAS SPAWNED CONVECTION MOVING THROUGH THE
NORTHERN CWA.  NOT REAL SURE AT THIS POINT IF CAP WILL BUST BY MAX
AFTERNOON HEATING...AND AT THIS POINT WILL LEAVE LOW ORDER POPS IN
THE NORTHERN ZONES TO ACCOUNT FOR THE EXITING SHORTWAVE.  CONVECTION
IN THE NORTHERN CWA HAS PRODUCED ONLY DIMES SO FAR...AND WILL NOT
MENTION ANYTHING SEVERE.  ALSO...IN CENTRAL TEXAS SURFACE OBS SHOW A
DRYLINE HAS SHARPENED UP AGAINST THE CAPROCK.  THIS FEATURE IS
PROGGED TO MERGE W/A COLD FRONT AND APPROACH THE 4-STATE AREA
TUESDAY AS THE NEXT SHORTWAVE MOVES THROUGH.  W/RETURN FLOW TO
CONTINUE OVERNIGHT...PUMPING SFC DEWPTS TO 70F OR BETTER BY
MORNING...AIRMASS AHEAD OF THE FRONT/DRYLINE WILL BE
PRIMED...W/PROGGED AFTERNOON SBCAPES OF 4000-5000 J/KG.  IN LIEU OF
THIS...WILL GO AHEAD AND MENTION POSSIBILITY OF SEVERE ACTIVITY
TUESDAY AND TUESDAY NIGHT.  OTHERWISE...WILL TAPER DOWN POPS THROUGH
WEDNESDAY EVENING...AND KEEP THE FORECAST DRY UNDER NW FLOW ALOFT
THROUGH SATURDAY MORNING.  SATURDAY AFTERNOON...BOTH THE NAM AND GFS
ADVERTISE A FAIRLY STRONG SHORTWAVE TO APPROACH THE AREA.  THE GFS
GENERATES THE SIGNATURE QPF BOMB...BUT SO DOES THE NAM.  THIS SHOULD
PROVIDE FOR A WET WEEKEND...AND EXIT NW-SE MONDAY.  FOR
TEMPS...PROGS INDICATE AT OR NEAR CLIMATOLOGY...AND GUIDANCE SEEMS
REASONABLE.
