AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
1035 PM CST THU FEB 20 2014

.DISCUSSION...SEVERE STORMS CONTINUE TO DEVELOP IN THE MOST AND
UNSTABLE AIR OVER SOUTHEAST/EAST MISSISSIPPI. DEWPOINTS WERE IN THE
LOWER TO MID 60S AND IT REMAINS UNSTABLE...SO THE RISK FOR TORNADOES
WILL CONTINUE. THE FRONT WAS STARTING TO CATCH UP TO SOME OF THE
EARLIER CONVECTION...SO MORE SEVERE STORMS WERE DEVELOPING FOR
CENTRAL MISSISSIPPI. A LARGE AREA OF RAIN HAS DEVELOPED OVER THE
WATCH AREA AND THE FLASH FLOOD POTENTIAL HAS INCREASED. HEAVY
DOWNPOURS WERE CAUSING FLOODING IN SEVERAL PLACES.

THE COLD AIR WAS STILL OVER NORTHWEST ARKANSAS AND
MAY NOT SPREAD ACROSS THE ENTIRE CWA TONIGHT. RAISED TEMPS ACROSS
THE AREA A FEW DEGREES AND TWEAKED HOURLY VALUES TO ACCOUNT FOR THE
WARMER TEMPERATURES. DRIER AIR WAS SLOWLY EASING THIS WAY...VALUES
WERE DOWN TO THE UPPER 30S IN GREENVILLE. MORE UPDATES TO
TEMPS/DEWPOINTS ARE LIKELY.

WINDS CONTINUE TO GUST ACROSS THE REGION...BUT ARE NOT QUITE
ADVISORY CRITERIA. ALTHOUGH GUSTS WILL OCCASIONALLY BE HIGHER...WILL
MAINTAIN 10 TO 20 KTS THROUGH TONIGHT.

&&

.AVIATION...THE RAIN HAS ENDED FOR GLH/GWO...SO VFR CONDITIONS SHOULD
PREVAIL THROUGH THE FORECAST PERIOD. FOR HKS/JAN...THERE WILL BE SHOWERS
AND THUNDERSTORMS THROUGH MIDNIGHT. GTR/MEI/HBG MAY HAVE RAIN THROUGH
8Z. THE WINDS HAVE DIMINISHED ACROSS THE AREA...BUT THERE MAY BE SOME
GUSTS FOR THE SITES WHERE THUNDERSTORMS WERE STILL PASSING. AFTER 12Z
VFR CONDITIONS WILL PREVAIL AT ALL SITES THROUGH 12Z SATURDAY.
