AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE JACKSON MS
932 PM CDT WED SEP 23 2009

.DISCUSSION...SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS CONTINUE
TO DRIFT NORTH ACROSS THE FORECAST AREA THIS EVENING.  WHILE THE
ACTIVITY HAS DISSIPATED A BIT IN INTENSITY...SOME POCKETS OF HEAVY
RAIN DO CONTINUE TO FALL OVER PORTIONS OF THE AREA.  AS A RESULT...
SOME LOCALIZED AREAS COULD SEE SOME RAINFALL RATES ON THE ORDER OF
1-2 INCHES IN JUST AN HOURS TIME.  THIS WILL LIKELY CAUSE SOME
PONDING OF WATER ON ROADS...AS WELL AS IN LOW LYING AND POOR
DRAINAGE AREAS.

WHILE MUCH OF THE ACTIVITY IS EXPECTED TO CONTINUE TO SLOWLY
DISSIPATE THROUGH THE LATE EVENING HOURS...A STALLED FRONT IS
ORIENTED NORTH TO SOUTH IN MY WEST NEAR THE MISSISSIPPI RIVER.
BECAUSE OF THIS...THE BETTER RAIN CHANCES THROUGH THE OVERNIGHT
HOURS WILL BE ACROSS AREAS ALONG AND WEST OF THE INTERSTATE 55
CORRIDOR.

THE FORECAST LOOKS IN PRETTY GOOD SHAPE FOR TONIGHT.  I WILL MAKE
SOME MINOR ADJUSTMENTS TO THE HOURLY GRIDS AS A RESULT OF CURRENT
TRENDS.  UPDATED PRODUCTS WILL BE SHIPPED MOMENTARILY.

&&

.AVIATION...A COMBINATION OF SCATTERED CONVECTION...STRATUS...AND
FOG THROUGH THE NIGHT WILL KEEP MVFR/IFR CEILINGS AT MOST LOCATIONS
THROUGH THE OVERNIGHT HOURS.  CONVECTION AND FOG WILL ALSO KEEP A
VARIETY OF VISIBILITIES ACROSS THE AREA TONIGHT AS SITES FOR THE
MOST PART THROUGH THIS EVENING WILL REMAIN VFR...BUT BRIEFLY DROP TO
MVFR/IFR STATUS WHERE CONVECTION IS OBSERVED.  THROUGH THE NIGHT
THOUGH...WITH FOG EXPECTED TO DEVELOP AT MOST LOCATIONS...
VISIBILITIES WILL FALL TO MVFR/IFR STATUS.  THIS WILL ESPECIALLY BE
THE CASE AT LOCATIONS ALONG AND EAST OF INTERSTATE 55...KJAN...
KGTR...KMEI...AND KHBG...WHERE VISIBILITIES AND CEILINGS COULD FALL
TO LIFR STATUS AROUND SUNRISE THURSDAY MORNING.  BOTH CEILINGS AND
VISIBILITIES WILL IMPROVE THROUGH THE MORNING HOURS THURSDAY.
HOWEVER...SCATTERED CONVECTION WILL AGAIN BE POSSIBLE AT ALL TAF
SITES THROUGH THE AFTERNOON AND EVENING HOURS THURSDAY.
