AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
300 PM CST WED FEB 15 2012

...HEAVY RAIN AND SOME SEVERE STORMS POSSIBLE LATE THIS AFTERNOON
AND TONIGHT...

.DISCUSSION...SHORT TERM(TONIGHT THROUGH FRIDAY NIGHT)
THE PRIMARY CONCERNS WILL BE FOR A STORM SYSTEM THAT WILL COME OUT
OF THE SOUTHERN PLAINS THAT WILL AFFECT THE REGION FOR LATE THIS
AFTERNOON INTO THE OVERNIGHT HOURS. THE ISSUES WILL BE FOR SOME
SEVERE POTENTIAL IN THE SOUTHWEST QUARTER FOR THIS EVENING AS WELL AS
LOCALLY HEAVY RAINS. THERE WILL ALSO BE SOME STRONG STORM ISSUES IN
THE SOUTHEAST QUARTER OVERNIGHT. SECONDARY ISSUES WILL BE THE RETURN
OF RAIN FOR FRIDAY INTO FRIDAY NIGHT...FOLLOWED BY POPS AND TEMPS.

LATEST SATELLITE IMAGERY SHOWED AN APPROACHING SHORT WAVE WITH AN ASSOCIATED
CLOSED LOW OVER THE SOUTHERN PLAINS. AN ASSOCIATED MCS WITH SOME
LINE SEGMENTS WAS CROSSING WESTERN LOUISIANA. ON THE SURFACE AN AREA
OF LOW PRESSURE WAS OBSERVED OVER OKLAHOMA WITH AN ASSOCIATED WARM
FRONT PUSHING NORTHEAST FROM OKLAHOMA THROUGH LOUISIANA TO
APPROACHING SOUTHWEST MISSISSIPPI. SO EXPECT THE MCS TO START TO
AFFECT NORTHEAST LOUISIANA AND SOUTHEAST ARKANSAS LATE THIS
AFTERNOON AND SPREAD EAST ACROSS THE REGION OVERNIGHT AS THE WARM
FRONT PUSHES NORTHEAST ACROSS THE REGION. THERE WILL BE ENOUGH
SHEAR...HELICITY AND SOME INSTABILITY FOR A FEW SEVERE STORMS IN THE
SOUTHWEST QUARTER OF THE REGION OVERNIGHT..GENERALLY ALONG AND SOUTH
OF I-20 AS WELL AS ALONG AND WEST OF I-55. AS THE MCS PUSHES EAST A
FEW STRONG STORMS WILL AFFECT THE SOUTHEAST QUARTER OF THE REGION.
THE BEST FORCING WITH THIS SYSTEM WILL LIFT NORTH OF THE REGION
DURING THE NIGHT. OVER THE SOUTHWEST AREAS LINE
SEGMENTS...SUPERCELLS AS WELL AS CLUSTERS OF SEVERE STORMS WILL BE
POSSIBLE. THE MAIN RISK WILL BE HAIL...DAMAGING WINDS AND A FEW
TORNADOES IN THE SOUTHWEST. OUR CHANCES OF THUNDERSTORMS WILL
DECREASE FROM THE NORTHWEST AFTER MIDNIGHT. THE ASSOCIATED COLD
FRONT WILL BE SLOW TO MOVE THROUGH THE REGION FROM THE WEST. EXPECT
ELEVATED CONVECTION TO PUSH INTO THE WEST FOR THIS AFTERNOON...THEN
SPREAD ACROSS THE REST OF THE REGION BY THIS EVENING. EXPECT IT TO
BECOME MORE SURFACE BASE IN THE WEST AND SOUTHWEST LATE THIS
AFTERNOON BEFORE SPREADING ACROSS MAINLY THE SOUTH HALF FOR TONIGHT.
HOWEVER IF WE DO NOT REACH THE EXPECTED INSTABILITY IT IS POSSIBLE
THAT IT COULD BE MORE OF A HEAVY RAIN EVENT. IN THE CASE OF HEAVY
RAIN OPTED NOT TO GO WITH A FLASH FLOOD WATCH WITH THE MOVEMENT OF
THIS SYSTEM. COULD SEE 1 TO 3 INCH AMOUNTS POSSIBLE. MODELS TRY TO
KEEP INSTABILITY ACROSS THE REGION WITH THE SLOW FRONTAL PASSAGE ON
THURSDAY. SO KEPT LOWER CONVECTIVE POPS FOR THURSDAY. A SOUTHERN
STREAM SYSTEM COMBINED WITH A GULF LOW WILL COME TO THE REGION FROM
THE WEST...WHICH WILL HELP TO SPREAD RAIN ACROSS THE REGION FOR
FRIDAY INTO FRIDAY NIGHT. IT WILL START OUT AS LIGHT RAIN DURING THE
DAY...THEN AS ISENTROPIC LIFT INCREASES IT WILL BECOME MODERATE RAIN
ON FRIDAY NIGHT. AS FAR AS TEMPS ARE CONCERN WENT WITH A BLEND OF
GMOS AND MAV NUMBERS. AS FAR AS POPS ARE CONCERN WENT WITH CURRENT
POPS FOR TONIGHT AS WELL AS A BLEND OF MAV AND NAM GUIDANCE./17/

.PREVIOUS LONG TERM DISCUSSION...SATURDAY THROUGH NEXT WEDNESDAY
SLIGHTLY COOLER DRIER CONDITIONS WILL EXIST OVER THE
FORECAST AREA HEADING INTO THE WEEKEND.  BEGINNING FRIDAY NIGHT
THOUGH...RAIN CHANCES WILL BE ON THE INCREASE OVER THE ARKLAMISS
REGION AS A SURFACE LOW DEVELOPS OVER THE NORTHWEST GULF OF MEXICO
IN RESPONSE TO A SHORTWAVE SWINGING EAST ACROSS THE SOUTHERN
PLAINS.  THIS SURFACE LOW WILL SHIFT EAST NORTHEAST ACROSS THE NORTH
CENTRAL GULF OF MEXICO DURING THE COURSE OF THE DAY SATURDAY CAUSING
RAIN TO SPREAD ACROSS THE MAJORITY OF THE FORECAST AREA...ESPECIALLY
THE SOUTHERN PORTION OF IT.  AS THE LOW LIFTS NORTHEAST ACROSS THE
FLORIDA PANHANDLE AND INTO SOUTHERN GEORGIA SATURDAY NIGHT...RAIN
CHANCES WILL GRADUALLY COME TO AN END FROM WEST TO EAST.  CLOUDS
LOOK TO HANG AROUND INTO SUNDAY MORNING THOUGH AS THE UPPER TROUGH
CONTINUES TO SWING ACROSS THE REGION.

ONCE AGAIN...WITH NORTHERLY FLOW OVER THE CWA...COOLER CONDITIONS
WILL EXIST ON SUNDAY AS SKIES CLEAR.  AFTER A COUPLE OF RAIN-FREE
DAYS SUNDAY AND MONDAY...RAIN CHANCES JUMP BACK INTO THE FORECAST
MONDAY NIGHT AND CONTINUE THROUGH WEDNESDAY AS YET ANOTHER SERIES OF
SYSTEMS ARE POISED TO DEVELOP TO OUR WEST...AND BEGIN TO SLOWLY
SHIFT EAST TOWARDS US. /19/17

&&
.AVIATION...
VFR CONDS WILL PREVAIL THRU THE REST OF THE AFTN...ACCOMPANIED BY
SRLY/SERLY WINDS OF 8-12KTS WITH OCSNL GUSTS. A FEW SHWRS HAVE BEGUN
TO CROSS NERN LA...WITH THE BRUNT OF SHWR/TSTM ACTIVITY MOVING EAST
OUT OF WEST-CENTRAL LA. THIS AREA WILL BEGIN TO IMPACT THE ARKLAMISS
LATE THIS AFTN INTO THE EVENING HOURS WITH LGT/MOD SHRA/RA POTENTIAL
CONTINUING INTO TONIGHT. MVFR/IFR CIG MAY DEVELOP AFTER THE RAIN
STARTS...ESPECIALLY LATER THIS EVENING/OVRNGT. VSBY RESTRICTIONS
BELOW 1 MILE WILL BE LIKELY IN THE HEAVIER DOWNPOURS. A COLD FRONT
WILL BEGIN PUSHING ACROSS THE REGION AS THE RAIN DEPARTS TOMORROW
MORNING WITH WINDS SHIFTING TO THE NW IN ITS WAKE. MVFR/IFR CIGS MAY
PERSIST TOMORROW MORNING BEFORE VFR CONDS RETURN MID/LATE MORNING.
