AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
355 AM CDT MON JUN 4 2012

...STRONG TO SEVERE STORMS POSSIBLE NORTHEAST TODAY...

.SHORT TERM...TODAY THROUGH TUESDAY NIGHT...ACTIVE WEATHER RETURNS
TO THE AREA TODAY AND CONTINUES TUESDAY. SHORTWAVES DIVING DOWN THE
BACKSIDE OF A LARGE CLOSED LOW CENTERED OVER THE NEW ENGLAND STATES
THIS MORNING...WILL AMPLIFY THE UPPER LEVEL TROUGHING OVER OUR
REGION THROUGH THE SHORT TERM AND SEND A NEARLY STATIONARY BOUNDARY
SOUTH AGAIN AND ACROSS THE OUR CWA TUESDAY AS A WEAK COLD FRONT.
THIS BOUNDARY WILL SERVE TO FOCUS CONVECTION THOUGH THE PERIOD. AN
EARLIER MCS THAT DEVELOPED ALONG THE STALLED BOUNDARY PUT OUT AND
OUTFLOW BOUNDARY THAT HAS EDGED INTO OUR NORTHEAST MOST ZONES EARLY
THIS MORNING. A SHORTWAVE OVER THE SOUTHERN PLAINS WAS HELPING
ADDITIONAL CONVECTION DEVELOP ALONG THE BOUNDARY THAT MAY TRACK
ACROSS OUR NORTHEAST ZONES LATER THIS MORNING AS INDICATED BY SOME
HIRES MODELS. BY THIS AFTERNOON THOUGH...PWS ACROSS OUR NORTH WILL
SURGE ABOVE AND INCH AND A HALF. MID LEVEL LAPSE RATES NEAR 6.75
C/KM AND VERTICAL TOTALS NEAR 29C WILL CONTRIBUTE TO THE POTENTIAL
FOR A FEW STRONG TO SEVERE STORMS INTO THIS EVENING MAINLY ALONG AND
NORTH OF A LINE FROM GREENWOOD TO DE KALB. WIND GUSTS TO 60 MPH AND
QUARTER SIZE HAIL WILL BE THE MAIN THREATS. MOST OF THE CONVECTION
WILL WEAKEN LATER THIS EVENING BUT MODELS SHOW CONVECTION GETTING AN
EARLY START TUESDAY MORNING AND EDGING INTO OUR NORTHERN MOST ZONES
JUST AHEAD OF THE COLD FRONT BY SUNRISE. THE NAM IS THE FASTEST AND
ECMWF THE SLOWEST WITH THE FRONT DROPPING SOUTH THROUGH THE CWA
TUESDAY. THERMODYNAMIC PARAMETERS LOOK A LITTLE WEAKEN BUT STILL
INDICATE A POTENTIAL FOR STRONG TO SEVERE STORMS ALONG AND SOUTH OF
THE FRONT. WL INCLUDE MENTION OF THIS MAINLY SOUTH OF HIGHWAY 82
TUESDAY AS THE COLD FRONT IS EXPECTED APPROACHING THE CENTRAL
PORTIONS OF OUR CWA DURING THE MAXIMUM DAYTIME HEATING. DRIER AIR
WITH UPPER 50 DEW POINTS AND PWS BACK BELOW AN INCH ARE EXPECTED
ACROSS THE NORTHERN HALF OF OUR CWA BY TUESDAY EVENING. THERE ARE
INDICATIONS THAT THE FRONT WILL BE VERY SLOW TO MOVE THROUGH THE CWA
AND ONLY BE JUST SOUTH OF I-20 BY WEDNESDAY MORNING CONTINUING TO
HELP SPAWN CONVECTION THROUGH THE NIGHT ACROSS OUR SOUTHERN ZONES.
HAVE GONE ABOVE MAV POPS ACROSS THE NORTHEAST TODAY AND THE SOUTHERN
HALF OF OUR AREA TUESDAY AND TUESDAY NIGHT. /22/

.LONG TERM...WEDNESDAY THROUGH MONDAY...MODELS LOOK TO HAVE COME
INTO BETTER AGREEMENT TONIGHT WITH BRINGING THE FRONT TO AROUND THE
HIGHWAY 84 CORRIDOR BY WEDNESDAY. A SHORTWAVE WILL HELP TO ENHANCE
CONVECTION ON WEDNESDAY MAINLY ALONG AND SOUTH OF THE STALLED
FRONTAL BOUNDARY. WITH ENOUGH INSTABILITY...MOISTURE AND VERTICAL
TOTALS AROUND 26-27C...CANT RULE OUT A FEW STRONG TO SEVERE STORMS
WEDNESDAY AFTERNOON SOUTH OF THE FRONT. HIGH PRESSURE FROM THE GREAT
LAKES REGION WILL SLOWLY FILTER INTO THE NORTHERN SECTIONS OF THE
CWA. THE GFS/SREF/GFS ENSEMBLES CONTINUE TO PUSH THE FRONT FURTHER
SOUTH OF THE AREA BY THURSDAY...WHILE THE ECMWF LINGERS IT IN THE
SOUTH THROUGH THURSDAY. HAVE CONTINUED WITH THE CONSENSUS FOR THIS
FORECAST PACKAGE WITH THE FRONT MOVING THROUGH THE ENTIRE AREA BY
THURSDAY. DRIER CONDITIONS WILL PREVAIL BUT TEMPERATURES WILL STILL
BE IN THE UPPER 80S/LOWER 90S AS UPPER RIDGING BUILDS OVER THE
REGION AS WELL AS HIGH PRESSURE AT THE SFC. THE ARKLAMISS WILL
REMAIN DRY FROM ABOUT THURSDAY THROUGH SATURDAY...WHEN A SHORTWAVE
FROM TEXAS BEGINS TO SLOWLY MOVE ACROSS THE REGION. THIS WILL HELP
TO BRING RAIN CHANCES BACK TO THE AREA FROM ABOUT SATURDAY THROUGH
AT LEAST MONDAY. /28/

&&

.AVIATION...VFR CONDITIONS WERE BEING REPORTED AT ALL TAF SITES AT
09Z AND WILL PREVAIL FOR THE MOST PART THROUGH TUESDAY. HOWEVER...
THERE WILL BE AN INCREASING RISK FOR TSTM ACTIVITY IN ASSOCIATION
WITH A SOUTHWARD MOVING FRONTAL BOUNDARY LATER TODAY INTO TUESDAY.
THE GREATEST RISK WILL INITIALLY EXIST FOR THE GLH-GWO-GTR
CORRIDOR...AND SHIFT TO AREAS ALONG AND SOUTH OF THE JAN-MEI
CORRIDOR BY LATE TUESDAY AND THEN HBG BY WEDNESDAY MORNING. /22/
