AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE JACKSON MS
1001 PM CDT MON NOV 23 2009

.DISCUSSION...CLOUDS ARE CONTINUING TO TRY AND BREAK UP FROM
SOUTHWEST TO NORTHEAST ACROSS THE FORECAST THIS EVENING...BUT IT`S
BEEN TO LITTLE OR NO AVAIL AS THEY`VE REDEVELOPED IN MOST PLACES.
WHERE THEY HAVEN`T REDEVELOPED THROUGH...THE COMBINATION OF THE
CLEARING SKIES...LIGHT WINDS...AND DAMP GROUND CONDITIONS HAS LEAD
TO THE DEVELOPMENT OF SOME PATCHY FOG OVER CENTRAL AND SOUTHERN
PORTIONS OF THE AREA.  HOWEVER...THE FOG POTENTIAL IS EXPECTED TO
SHIFT FURTHER EAST OVER EAST AND SOUTHEAST MISSISSIPPI THROUGH THE
OVERNIGHT HOURS AS WINDS BEGIN TO PICK UP ACROSS WESTERN PORTIONS OF
THE AREA DUE TO A FRONTAL SYSTEM APPROACHING THAT AREA FROM THE WEST.

WITH CLOUDS REDEVELOPING ACROSS MUCH OF THE AREA...I`VE RAISED LOW
TEMPERATURES IN SEVERAL PLACES TONIGHT PARTICULARLY IN THE EAST.
OTHER THAN THIS...ALONG WITH SOME MINOR TWEAKS TO SKY COVER AND
HOURLY GRIDS AS A RESULT OF CURRENT TRENDS...THE REMAINDER OF THE
FORECAST LOOKS IN DECENT SHAPE.  NO OTHER ADJUSTMENTS WILL BE MADE
TO THE FORECAST AT THIS TIME.

UPDATED PRODUCTS ARE SHIPPING.

.AVIATION...LOOK FOR VFR CEILINGS TO PREVAIL AT MOST SITES THROUGH
MUCH OF THE NIGHT.  HOWEVER...PATCHY GROUND FOG OVER PORTIONS OF
CENTRAL AND SOUTH MISSISSIPPI THIS EVENING COULD BRIEFLY REDUCE
VISIBILITIES TO MVFR STATUS.  A COLD FRONT WILL PUSH CLOSER TO
WESTERN PORTIONS OF THE AREA OVERNIGHT.  THIS WILL CAUSE WINDS TO
PICK UP A BIT IN THAT AREA WHICH WILL BEGIN TO HAMPER FOG
DEVELOPMENT THERE AFTER MIDNIGHT.  WITH CLEAR AND LIGHTER WINDS
EXPECTED FURTHER EAST THOUGH...OFF AND ON MVFR VISIBILITIES WILL BE
POSSIBLE AFTER MIDNIGHT ACROSS MAINLY EAST AND SOUTHEAST
MISSISSIPPI...WITH IFR/LIFR VISIBILITIES POSSIBLE BY DAY BREAK
TUESDAY MORNING.  ANY FOG THAT DEVELOPS TONIGHT SHOULD DISSIPATE IN
MOST LOCATIONS BETWEEN 14-15Z TUESDAY.  AFTER THAT...LOOK FOR MORE
BROKEN STRATUS TO DEVELOP TUESDAY AHEAD OF THE BEFORE MENTIONED COLD
FRONT AS IT MOVES WEST TO EAST ACROSS THE AREA TUESDAY AFTERNOON
INTO TUESDAY NIGHT.  A FEW SHOWERS...ESPECIALLY IN THE NORTH WILL BE
POSSIBLE WITH THE COLD FRONT AS IT PUSHES THROUGH TUESDAY.

.JAN WATCHES/WARNINGS/ADVISORIES...
MS...NONE.
LA...NONE.
AR...NONE.
