AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
1057 PM CDT THU APR 24 2014

.UPDATE...THE FORECAST WAS GOOD FOR TONIGHT. MADE A FEW ADJUSTMENTS
TO ADD SEVERE AND HEAVY RAIN WORDING FURTHER EAST. LOOKS LIKE THINGS
WERE CALMING DOWN...WITH ONE SEVERE STORM STILL MOVING THROUGH THE
EASTERN ZONES. HOWEVER SHOWERS AND THUNDERSTORMS WILL LINGER FOR A
WHILE LONGER. THE MAIN BOUNDARY WAS JUST MOVING INTO WEST
MISSISSIPPI...WITH A LINE OF SHOWERS. THE DEWPOINTS WERE FALLING
QUICKLY BEHIND THE BOUNDARY...ALTHOUGH THE TEMPS WERE STILL IN THE
60S ACROSS ARKANSAS. LOOKS LIKE VALUES WILL FALL SLOWLY TONIGHT...SO
ADJUSTED THE HOURLY VALUES. WITH WINDS STILL OUT OF THE SOUTH FOR
MOST OF THE CWA...WILL LIKELY NEED TO RAISE OVERNIGHT LOWS. CLOUDS
WERE SPREADING ACROSS THE AREA...MODELS SHOW THEM PASSING.

&&
.AVIATION...SHOWERS AND THUNDERSTORMS WILL CONTINUE FOR GTR FOR THE
NEXT HOUR...MAYBE A LITTLE LONGER. OTHERWISE...LOOK FOR A SLIGHT
CHANCE OF SHOWERS AND THUNDERSTORMS AS A BOUNDARY MOVES THROUGH THE
REGION. WINDS WILL SHIFT AND INCREASE BEHIND THE BOUNDARY. CEILINGS
MAY FALL TO MVFR RANGE FROM 6-12Z FOR JAN/HBG/MEI. THERE MAY ALSO BE
SOME PATCHY FOG. WITH CLOUDS LINGERING FOR GLH/GWO/GTR...MAY NOT SEE
AS MUCH FOG IN THOSE AREAS. WINDS MAY GUST BRIEFLY FOR GLH/GWO
OVERNIGHT.
