AREA FORECAST DISCUSSION...UPDATED FOR AVIATION
NATIONAL WEATHER SERVICE JACKSON MS
608 AM CST WED MAR 10 2010

.SHORT TERM...TODAY AND TONIGHT...SHOWERS AND THUNDERSTORMS ONGOING
ACROSS THE EASTERN HALF OF THE CWA...GENERALLY ALONG AND SOUTHEAST
OF THE NATCHEZ TRACE(WITH ANOTHER SMALL BAND JUST TO THE NORTH OF
THE TRACE). A FEW OF THESE STORMS HAVE BECOME STRONG TONIGHT WITH
HAIL BEING THE MAIN THREAT...AND THEY ARE PRODUCING QUITE A BIT OF
LIGHTNING.

FOR TODAY...EXPECT THE EASTERN PORTIONS OF MY CWA TO CONTINUE TO SEE
THE BEST CHANCE FOR RAIN THROUGH THE DAY AS SOME WEAK
IMPULSES/FORCING MOVES THROUGH THE REGION FROM THE SOUTHWEST IN TO
ALABAMA AND LINGERS IN THE EAST. NOT EXPECTING A WHOLE LOT OF
COVERAGE IN THE WEST AS THERE SHOULD BE A BREAK BEFORE THE NEXT WAVE
OF STORMS. THIS IS ALSO SUPPORTED GENERALLY BY LOCAL WRF AND HI-RES
NATIONAL WRF MODELS. HOWEVER WITH THAT BEING SAID...AS WE GO INTO
THE AFTERNOON PERIOD...INSTABILITY WILL BE GOOD(WITH CAPE VALUES
EXCEEDING 1000J/KG) AS WELL AS LAPSE RATES/VERTICAL TOTALS OF
28-30...PLENTY OF MOISTURE(AS THE LOWER TO MID 60S DEWPOINTS HAVE
BECOME ESTABLISHED OVER THAT AREA) AND COUPLED WITH THE INFLUENCE OF
THE FAVORABLE LEFT FRONT QUAD OF A 190KT UPPER JET...ANY SORT OF
CONVECTION THAT DOES GET GOING IN THE WEST WILL HAVE THE POTENTIAL
TO BECOME STRONG TO SEVERE AS WELL AS THE CONVECTION OVER IN THE
EAST.

WHILE THERE REMAINS THE CHANCES FOR SVR WX DURING THE
AFTERNOON...THINK THE BULK OF THE ACTIVITY SHOULD WAIT A LITTLE
LATER INTO THE LATE AFTERNOON AND EVENING HOURS...CONTINUING INTO AT
LEAST THE BEGINNING OF THE OVERNIGHT AND MODELS ARE A LITTLE SLOWER
THAN THEY WERE PREVIOUSLY IN THIS REGARD. IT SHOULD BE AT THIS
PERIOD...FROM ABOUT 00Z-06Z THAT THE BEST FORCING OF THE VERTICALLY
STACKED LOW PRESSURE SYSTEM MOVES INTO THE REGION. WHILE IT WILL BE
HARD TO PINPOINT AN EXACT AREA FOR SEVERE WEATHER...SOME OF THE
BETTER HEIGHT FALLS AND ASCENT SHOULD BE IN THE NORTHWEST DELTA
REGION DURING THIS TIME...AS THIS IS CLOSER TO THE UPPER LOW SYSTEM.
IN ADDITION...THIS IS WHERE THE BEST INSTABILITY REMAINS ALONG WITH
GOOD LAPSE RATES. I ALSO THINK THAT THE SOUTHWEST PORTION OF THE CWA
MIGHT BE JUST CAPPED ENOUGH TO NOT GET AS MUCH. WHILE ALL HAZARDS OF
SEVERE WEATHER CANNOT BE RULED OUT...FEEL THAT SOME OF THE GREATER
RISK WILL COME FROM LARGER HAIL AS IT WILL REMAIN COLD ALOFT. THERE
IS A DECENT WIND THREAT TOO AS DRIER AIR PUNCHING IN FROM THE WEST
BEHIND THE COLD FRONT/BOUNDARY COULD BRING A GREATER DAMAGING WIND
THREAT. HOWEVER...DEEP LAYER SHEAR IS NOT THE BEST ALONG WITH LOWER
SR HELICITIES...AS WELL AS A LACK OF A REALLY GOOD
BOUNDARY...THIS MAY LIMIT THE TORNADO THREAT SOME BUT STILL BELIEVE
THIS IS NON-ZERO. AS FOR SVR MODE...THINK THERE IS THE POSSIBILITY
FOR SOME SUPERCELLS TO FORM LATE AFTERNOON/EARLY EVENING AND AS THE
MAIN FORCING GETS CLOSER THIS WILL LIKELY CONGEAL INTO A LINEAR
SYSTEM AS IT MOVES THROUGH THE AREA OVERNIGHT...ESPECIALLY ACROSS
THE NORTHERN SECTIONS OF THE CWA. AS FOR FLOODING...THIS IS
CERTAINLY NOT OUT OF THE QUESTION TO GET SOME LOCALIZED FLOODING BUT
WIDESPREAD FLASH FLOODING IS NOT ANTICIPATED AS CONVECTION SHOULD BE
MORE SCATTERED RATHER THAN WIDESPREAD THROUGH THE EVENT.

AS WE GET CLOSER TO THURSDAY DAYBREAK...ACTIVITY SHOULD BE MOVING
OFF TO THE EAST AND ENTERING ALABAMA. AS FOR FORECAST
DETAILS...GENERALLY FOLLOWED MAV GUI BUT DID DECREASE POPS IN THE
SOUTHWEST FOR TONIGHT AS I AM NOT SURE HOW MUCH CONVECTION CAN GET
GOING DOWN THERE BEING FARTHER AWAY FROM THE MAIN ASCENT AND ANY
CAPPING THAT CAN STICK AROUND. DID ALSO INCREASE POPS IN THE EAST
SOME TODAY AS THIS IS WHERE THE BETTER ASCENT WILL RESIDE. TEMPS
WILL REMAIN WARM AS CLOUDS AND GENEROUS WAA WILL CONTRIBUTE TO HIGHS
IN THE 70S AND LOWS IN THE UPPER 50S AND LOWER 60S. /28/

.LONG TERM...THURSDAY THROUGH SUNDAY...

SUBSIDENCE AND MUCH DRIER AIR WILL FOLLOW PASSAGE OF THE SHORTWAVE
TROUGH FOR THURSDAY...BUT LOW LEVEL COLD ADVECTION WILL LAG WELL
BEHIND AS TEMPERATURES ARE EXPECTED TO SOAR WELL INTO THE 70S BY
THURS AFTN. A CLOSED UPPER LOW OVER THE MIDWEST IS FORECAST BY ALL
MODELS TO DIG SOUTHEAST TOWARD THE TN VALLEY FRIDAY THROUGH
SATURDAY. INCREASING CYCLONIC FLOW AND SUBSTANTIAL HEIGHT FALLS WILL
BRING COOLER AIR AND CHANCES FOR LIGHT RAIN TO THE ARKLAMISS FRIDAY
THROUGH SATURDAY. HAVE CUT GFS MOS GUIDANCE TEMPERATURES BY SEVERAL
DEGREES SATURDAY WITH THE EXPECTATION FOR A STRATOCUMULUS DECK AND
LIMITED SUNSHINE. RISING HEIGHTS AND INCREASED LARGE SCALE
SUBSIDENCE WILL RESULT IN MORE SUN SUNDAY AND WARMER TEMPERATURES
CLOSER TO CLIMATIC AVERAGE.

MONDAY THROUGH NEXT WEDNESDAY...THE GFS/ECMWF/UKMET/GEFS ARE ALL IN
REASONABLE AGREEMENT IN DIGGING STRONG SOUTHERN STREAM SHORTWAVE
ENERGY SOUTHEAST ACROSS TX AND TOWARD THE GULF COAST EARLY NEXT
WEEK. THE PROSPECT EXISTS FOR A SFC LOW PRESSURE SYSTEM TO DEVELOP
IN THE NRN GULF OF MEXICO RESULTING IN COOL AND RAINY CONDITIONS...
BUT MODELS DIVERGE ON TRAJECTORY/INTENSITY OF THE SHORTWAVE TROUGH
SO CONFIDENCE IS LOW REGARDING RAINFALL INTENSITY. HAVE CUT GFS
GUIDANCE HIGH TEMPERATURES FOR TUES/WED AS THEY SEEM TOO SKEWED
TOWARD CLIMATOLOGY. /EC/

&&

.AVIATION...MVFR TO IFR CEILINGS BEING SEEN THIS MORNING AS SHOWERS
AND THUNDERSTORMS AFFECT PORTIONS OF EASTERN MISSISSIPPI. BACK TO
THE WEST...WHILE THUNDERSTORM ACTIVITY HAS QUIETED...LOW CLOUDS
REMAIN. CLOUDS SHOULD REMAIN FAIRLY LOW TODAY THOUGH MIGHT LIFT TO
AROUND 2KFT THIS AFTERNOON. THINK THE BEST RAIN CHANCES WILL STAY IN
THE EAST WITH POSSIBLE TSRA THERE AS WELL. NOT SURE THAT THEY WILL
PREVAIL SO LEFT SOME IN TEMPO GROUPS. FEEL THE WEST SHOULD HAVE A
BREAK FROM THE RAIN THROUGH MUCH OF THE DAY AND THEN ANOTHER ROUND
OF SHOWERS AND THUNDERSTORMS TONIGHT AFTER 00Z AS ANOTHER UPPER
LEVEL SYSTEM MOVES CLOSE TO THE AREA. AS THIS OCCURS FROM LATE
AFTERNOON THROUGH THE EVENING AND OVERNIGHT HOURS...THERE IS THE
POTENTIAL FOR SOME STORMS TO BE SEVERE WITH HAIL AND WIND BEING THE
MAIN THREAT.CEILINGS SHOULD DROP IN THUNDERSTORMS TO IFR AND LIFR
CATS AS WELL AS VISIBILITIES. THE RAIN SHOULD MOVE FROM WEST TO EAST
AND MOST ALL TAF SITES WILL BE AFFECTED DURING THIS TIME. MUCH OF
THE RAIN SHOULD BE OUT OF THE REGION BY AROUND 12-14Z THURSDAY. /28/

THIS HAZARDOUS WEATHER OUTLOOK IS FOR CENTRAL MISSISSIPPI...
NORTHEAST LOUISIANA...AND EXTREME SOUTHEAST ARKANSAS.

.DAY ONE...TODAY AND TONIGHT

ISOLATED STRONG THUNDERSTORMS AND POSSIBLY A SEVERE THUNDERSTORM
WILL OCCUR EAST OF THE INTERSTATE 55 CORRIDOR THIS MORNING INTO
EARLY AFTERNOON. THE PRIMARY HAZARD WITH THIS ACTIVITY WILL BE FROM
HAIL UP TO QUARTER SIZE.

SEVERE THUNDERSTORMS WILL BE LIKELY ACROSS THE ARKLAMISS REGION FOR
THIS EVENING THROUGH TONIGHT ESPECIALLY FOR LOCATIONS ALONG AND
NORTHEAST OF A BASTROP LOUISIANA...TO JACKSON...TO HATTIESBURG LINE.
THE PRIMARY HAZARDS WITH THESE THUNDERSTORMS WILL BE HAIL FROM
QUARTER TO GOLF BALL SIZE...DAMAGING WIND GUSTS IN EXCESS OF 60
MPH...ALONG WITH TORNADOES. MODERATE INSTABILITY AND INCREASING WIND
SHEAR WILL COMBINE AHEAD OF AN APPROACHING UPPER LEVEL STORM SYSTEM
TO BRING THIS THREAT FOR SEVERE WEATHER TO THE REGION.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY

THE PROBABILITY FOR WIDESPREAD HAZARDOUS WEATHER IS LOW.

.SPOTTER CALL TO ACTION STATEMENT...
THE ACTIVATION OF STORM SPOTTERS...HAM RADIO OPERATORS...AND
EMERGENCY MANAGEMENT PERSONNEL IN SUPPORT OF SEVERE WEATHER
OPERATIONS...WILL LIKELY BE NEEDED THIS AFTERNOON THROUGH TONIGHT.
