AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
215 PM CDT THU OCT 11 2001

...TWO PERIODS OF STRONG TO SEVERE THUNDERSTORMS ARE EXPECTED ACROSS
THE FORECAST AREA THE NEXT SEVERAL DAYS...FOLLOWED BY AN EXTENDED
PERIOD OF COOL AND DRY WEATHER...

PERIODS OF RAIN AND THUNDERSTORMS...SOME SEVERE WITH STRONG WINDS
LARGE HAIL...AND POSSIBLY A TORNADO...WILL BE ONGOING INTO THE
EVENING HOURS TONIGHT. A 500 MB TROUGH EXTENDS SOUTHWARD FROM
MINNESOTA INTO THE TEXAS PANHANDLE. AHEAD OF THIS TROUGH...A SURFACE
FRONTAL BOUNDARY IS NEARLY STATIONARY FROM SOUTHERN ILLINOIS
SOUTHWARD INTO EASTERN TEXAS. NUMEROUS SHOWERS AND THUNDERSTORMS
HAVE DEVELOPED IN THE WARM UNSTABLE AIR AHEAD OF THIS FRONTAL
BOUNDARY. SEVERAL TORNADO WATCHES HAVE ALREADY BEEN ISSUED. TORNADO
WATCHES COVER THE ENTIRE FORECAST AREA. THE MISSISSIPPI PORTION OF
THE WATCH IS VALID TILL 6 PM WITH ARKANSAS COUNTIES AND LOUISIANA
PARISHES WEST OF MISSISSIPPI IN A TORNADO WATCH TILL 3 PM. EXPECT
THIS STRONG THUNDERSTORM ACTIVITY TO CONTINUE TO PROGRESS
EAST-NORTHEASTWARD INTO THE EVENING HOURS. AT THIS POINT...BELIEVE
THE BEST SEVERE THREAT INTO THIS EVENING WILL MAINLY BE WEST OF A
COLUMBUS TO PHILADELPHIA TO COLUMBIA...MISSISSIPPI LINE...BUT THE
ENTIRE FORECAST AREA IS UNDER A TORNADO WATCH. THE STRONGEST
RAINFALL ACTIVITY SHOULD BE EAST OF THE AREA BY LATE TONIGHT...WITH
MINIMAL CHANCES OF RAIN DURING THE DAY ON FRIDAY.

THE ETA AND AVN MODELS ARE IN DECENT AGREEMENT THROUGH 00Z SATURDAY.
THEN...THE AVN IS MUCH FASTER TO MOVE A STRONG 500 MB TROUGH
EASTWARD. THE AVN IS ALSO SIGNIFICANTLY FASTER IN MOVING A SURFACE
LOW NORTHEASTWARD INTO NORTHEAST TEXAS BY 06Z SATURDAY. SINCE THE
AVN FORECAST IS MORE CONSISTENT WITH PREVIOUS MODEL RUN...WILL STICK
WITH THIS MODEL FORECAST FOR THIS ZONE PACKAGE. USING AVN MODEL
FORECAST...BELIEVE STRONG THUNDERSTORMS WILL MOVE ACROSS THE
FORECAST AREA FROM LATE FRIDAY NIGHT INTO SATURDAY AHEAD OF THE
SURFACE FRONT. THE 300 MB JET PATTERN SHOULD ALSO PRODUCE GOOD UPPER
LEVEL DIVERGENCE TO FURTHER ENHANCE DEVELOPMENT OF STRONG
THUNDERSTORMS FROM FRIDAY NIGHT INTO SATURDAY. MOST OF THE RAINFALL
SHOULD BE EAST OF THE FORECAST AREA BY SATURDAY EVENING. FOR FRIDAY
NIGHT/SATURDAY RAINFALL EVENT...WILL KEEP MENTION OF SEVERE OUT OF
FORECAST AT THIS TIME DUE TO TIME AND LOCATION UNCERTAINTIES FOR
THIRD AND FOURTH PERIOD. HOWEVER...DO BELIEVE A SIGNIFICANT SEVERE
WEATHER SITUATION IS DEVELOPING BEGINNING FRIDAY NIGHT.

FOR TEMPERATURES...THE DIURNAL RANGE OF TEMPERATURES SHOULD BE
LIMITED THE NEXT SEVERAL DAYS DUE TO PLENTIFUL CLOUDINESS IN THE
MOIST LOW LEVEL SOUTHERLY FLOW. WILL STICK CLOSEST TO NGM MOS
GUIDANCE SINCE I THINK THE WARMER MINIMUMS ARE MORE LIKELY THE NEXT
TWO NIGHTS. EXPECT MINIMUM TEMPERATURES AROUND 50 DEGREES TO PREVAIL
BY SATURDAY NIGHT ACROSS THE ENTIRE FORECAST AREA.

QPF...00Z FRI - 00Z SAT...EXPECT MAIN PRECIPITATION AREA TO SHIFT
INTO EASTERN MISSISSIPPI BY THIS EVENING WITH 24 HOUR QPF AMOUNTS OF
1 TO 1.5 INCHES IN EASTERN SECTIONS...MAINLY DURING THE NIGHT
TONIGHT. GENERALLY EXPECT LESS THAN ONE FOURTH OF AN INCH OF
ADDITIONAL RAINFALL TONIGHT IN ARKANSAS COUNTIES AND LOUISIANA
PARISHES WEST OF THE MISSISSIPPI RIVER.

.EXTENDED FORECAST...
HIGH PRESSURE WILL DOMINATE WX OVER CENTRAL PORTION OF COUNTRY. DRY
DAYS WITH COOL NIGHTS EXPECTED THROUGH MID WEEK. TEMPERATURES SHOULD
BE SLIGHTLY BELOW NORMAL.

.PRELIM NUMBERS...
JAN 068/083/070/074  +277
