Damaging Wind in Louisiana, June 18, 2013

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
341 PM CDT TUE JUN 18 2013

.SHORT TERM...
SCATTERED CONVECTION ACROSS THE AREA NOW. THE DRAPING FRONT IS
CURRENTLY BETWEEN THE HWY 82 AND THE I-20 CORRIDORS.
INSTABILITY-WISE...THERE DOESN'T SEEM TO BE ENOUGH TO ALLOW THE
FORMATION OF STRONGER OR WIDESPREAD STORMS DESPITE THERE BEING HIGH
PWS AND PLENTY OF MOISTURE. THE MENTION OF HEAVY RAINFALL WAS
THEREFORE TAKEN OUT OF THE HWO FOR THIS EVENING. THE FRONT SHOULD BE
NEAR THE I-20 CORRIDOR SOMEWHERE AROUND SUNSET AND SO THE MAJORITY
OF THE RAINFALL SHOULD BE CONFINED TO AREAS SOUTH OF THAT.

A SHORTWAVE CURRENTLY OVER WESTERN LOUISIANA WILL BE TRAVELING
SOUTHEASTWARD THIS EVENING AND OVERNIGHT AND SO POPS WILL REFLECT
CHANCES FOR CONTINUED STORMS. THE FRONT WILL CONTINUE TO DROP DOWN
AND SETTLE ALONG THE COAST WEDNESDAY AND THEN EVENTUALLY FADE OUT
WEDNESDAY NIGHT OR THURSDAY. CHANCES FOR SHOWERS AND STORMS ALONG THE
STALLED FRONT IN OUR SOUTHERN COUNTIES EXISTS AGAIN TOMORROW. THE
CLOUDS TODAY BROUGHT SOME RELIEF IN TEMPERATURES BUT OTHERWISE THIS
FRONT WILL HAVE NO AFFECT ON OUR TEMPS THE NEXT DAY OR TWO AND THEY
WILL BE BACK TO NORMAL TOMORROW. PATCHY FOG WILL BE LIKELY IN AREAS
THAT DON'T RECEIVE RAIN OVERNIGHT AND WHERE THE CLOUD COVER HAS
CLEARED OUT...MOSTLY IN THE NORTHERN COUNTIES. THURSDAY SHOULD BE HOT
BUT RELATIVELY QUIET THEN AS AN UPPER RIDGE EXPANDS INTO THE PLAINS
AND HIGH PRESSURE BUILDS INTO THE SOUTH. /10/

LONG TERM...THURSDAY THROUGH NEXT TUESDAY...A SURFACE BOUNDARY
WILL RESIDE JUST SOUTH OF THE FORECAST AREA THURSDAY INTO
FRIDAY...WHILE UPPER RIDGING BUILDS OVER THE LOWER MISSISSIPPI RIVER
VALLEY.  THIS WILL ALLOW A SLIGHT DRYING OF OUR AIRMASS AND AT
PRESENT...AT LEAST A COUPLE OF DAYS TO DRY OUT AS FAR AS RAINFALL IS
CONCERNED.

THIS DOESN'T LOOK TO LAST LONG THOUGH AS BOTH RAIN CHANCES AND THE
HUMIDITY LOOK TO RETURN DURING THE WEEKEND AND HANG ON INTO THE NEW
WORK WEEK.  A PIECE OF UPPER LEVEL ENERGY LEFT BY A DEPARTING UPPER
TROUGH OVER THE EAST COAST...IS FORECAST TO MEANDER ABOUT ALONG THE
NORTH CENTRAL GULF COAST.  THIS FEATURE...COMBINED WITH DAYTIME
HEATING AND AMPLE MOISTURE OVER THE FORECAST AREA...LOOKS TO AID IN
THE DEVELOPMENT OF CONVECTION EACH AFTERNOON THROUGH THE REMAINDER
OF THE PERIOD...ESPECIALLY ACROSS EAST AND SOUTHEAST MISSISSIPPI.

AS FAR AS TEMPERATURES ARE CONCERNED...GUIDANCE SUGGESTED HIGHS AND
LOWS LOOK REASONABLE.  HIGHS EACH AFTERNOON WILL RANGE IN THE LOW TO
MID 90S...WHILE LOWS EACH NIGHT GENERALLY RANGE FROM THE MID 60S TO
AROUND 70. /19/

&&

.AVIATION...
WITH THE EXCEPTION OF GLH-GWO SCATTERED TO NUMEROUS TSTMS WL MOVE
ACROSS THE AREA THIS AFTN AND EVNG. OUTSIDE OF TSTM AREAS...VFR CONDS
WL PREVAIL. THE TSTM ACTIVITY WL DECREASE THIS EVNG. MVFR/IFR
CEILINGS/FOG WL BE POSSIBLE BY 10Z ACROSS CNTRL AND SOUTH WHERE A
WEAK COLD FRONT WL RESIDE. CONDS SHOULD IMPROVE BY 15Z. VFR CONDS
SHOULD PREVAIL AT MOST SITES WEDNESDAY WITH SCATTERED AFTN AND EVNG
TSTMS ACROSS THE HWY 84 CORRIDOR. /22/
