AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
300 PM CST SUN FEB 13 2000

FROM THE CURRENT RADAR AND SATELLITE TRENDS STILL PREFER THE ETA AS
THE MODEL OF CHOICE TODAY. BOTH THE ETA AND AVN PICKED UP ON THE
STRONG SHORTWAVE THAT MOVED AROSS TEXAS THIS MORNING...BUT STILL
FEEL THE AVN IS TOO FAST WITH THE SPEED AND DEEPENING OF THE SURFACE
LOW.

CURRENTLY STRONG/SEVERE THUNDERSTORMS ARE DEVELOPING FROM WEST
TENNESSEE BACK THROUGH SOUTHWEST LOUISIANA. THE STORMS ARE RAPIDLY
MOVING TO THE NORTHEAST. PARAMETERS FROM THE MID DAY SOUNDINGS SHOW
LAPSE RATES STILL STEEP...ON THE ORDER OF 7-7.5 C/KM...SWEAT INDICES
OF 450...WITH CAPES AROUND 1000 J/KG AND LIS OF -3 TO -5. A LOOK AT
CURRENT READINGS ACROSS THE FORECAST AREA SHOWS LIS OF -6 TO -8
OVER SOUTH ARKANSAS AND NORTHEAST LOUISIANA WITH DECENT PRESSURE
FALLS ACROSS THE CWFA. FROM MODEL TIMING AND CURRENT TRENDS MOST OF
THE ACTIVITY SHOULD BE EAST OF THE AREA BEFORE MIDNIGHT.

TIME SECTIONS SHOW DRIER AIR FILTERING IN FROM THE NORTHWEST LATE
TONIGHT. BY MONDAY MORNING...SURFACE COLD FRONT SHOULD BE ACROSS THE
EXTREME SOUTHEAST PORTION OF THE STATE...WITH HIGH PRESSURE
SETTING UP OVER THE STATE DURING THE DAY MONDAY. HIGH PRESSURE
CENTER SHOULD BE TO THE NORTHEAST BY EARLY TUESDAY. LOW LEVEL FLOW
BECOMES SOUTHERLY AGAIN ON TUESDAY...BUT STRONG RIDGE SHOULD KEEP
CONDITIONS DRY MONDAY THROUGH TUESDAY...AS A WARMING TREND ENSUES.

FOR THE FIRST PERIOD WILL GO ABOVE MOS WITH AS FAR AS POPS ARE
CONCERNED. NOT MUCH CHANGE FROM TEMPS...WILL TAKE AN AVERAGE AND MAY
VARY AROUND.

QPF DISCUSSION: SWIFT-MOVING SYSTEM LIMITS POTENTIAL FOR WIDESPREAD
...EFFICIENT HEAVY RAINFALL DEVELOPMENT. EXPECT LOCALLY HEAVIER
AMOUNTS IN STRONGER STORMS...MAINLY OVER NORTHERN COUNTIES. WILL GO
ALONG WITH NCEPS TRENDS FOR TIMING. EXPECT EVENT IS OVER AROUND 06Z
MOST AREAS EXCEPT SLIGHTLY LATER OVER EASTERN ZONES (11Z). LIGHTER
AMOUNTS THIS RUN OF MODELS ARE PREFERRED AND ACCEPTABLE. WILL GO WITH
AMOUNTS AROUND ONE QUARTER INCH OVER NORTH AND ONE TENTH TO ONE
QUARTER OTHERWISE.
