AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE JACKSON MS
1115 AM CDT THU MAY 26 2011

.MESOSCALE UPDATE...MAIN FRONTAL BOUNDARY CURRENTLY EXTENDS FROM
MACON TO BUDE. EXTRAPOLATION SHOWS THIS BOUNDARY REACHING THE I-59
CORRIDOR BY AROUND 20Z...BUT IT HAS BEEN SLOWING WITH TIME AND RUC
WOULD IMPLY IT WILL TAKE MOST OF THE DAY IF NOT EVENING FOR THE
BOUNDARY TO COMPLETELY CLEAR THE AREA. STORMS ARE FORMING ALONG THE
BOUNDARY AS WELL AS IN A THETA-E AXIS RUNNING ALONG THE I-59
CORRIDOR. WOULD EXPECT THAT THE COMBINATION OF DAYTIME HEATING AND
FORCING FROM A WAVE ROTATING AROUND THE UPPER LOW AS APPARENT ON
WATER VAPOR IMAGERY WILL LEAD TO A GRADUAL INVIGORATION OF
CONVECTION THROUGH THE DAY OVER EAST CENTRAL AND SE MS. SPC
MESOANALYSIS SHOWS THAT MLCAPE VALUES HAVE ALREADY REACHED 2000-2500
J/KG AND COMBINED WITH EFFECTIVE SHEAR OF 25-30 KT WOULD EXPECT
ORGANIZED MULTICELLS AND POSSIBLE SUPERCELLS WITH THE POSSIBILITY OF
SOME REPORTS OF LARGE HAIL AND 60 MPH WINDS. TORNADO THREAT IS
MINIMAL BUT NOT ZERO GIVEN 0-1 KM HELICITY VALUES OF AROUND 150
M2/S2 OVER SE MS AND AROUND 15-20 KT OF 0-1 KM SHEAR.  HRRR IMPLIES
GREATEST SEVERE THREAT WILL BE THROUGH AROUND 21Z WITH A GRADUAL
DECREASE IN CONVECTIVE INTENSITY AFTER THAT TIME.

&&

.AVIATION...COLD FRONT ORIENTED NORTHEAST TO SOUTHWEST ALONG A KGTR
TO KJAN TO KHEZ LINE AS OF 10AM WILL CONTINUE TO SHIFT EASTWARD
THROUGH THE DAY TODAY. AHEAD OF THE FRONT...MVFR TO VFR CONDITIONS
WILL EXIST AS LOW STRATUS SLOWLY BREAKS UP. RAIN SHOWERS AND
THUNDERSTORMS WILL ONCE AGAIN BE A POSSIBILITY ALONG AND AHEAD OF
THE FRONT THIS AFTERNOON FOR SOUTHEASTERN AREAS. SOME STORMS MAY
BECOME STRONG TO SEVERE WITH DAMAGING WINDS AND HAIL AS PRIMARY
THREATS. BEHIND THE FRONT...INITIAL CLEARING WILL OCCUR BUT WRAP
AROUND MOISTURE WILL BRING IN 3-4 KFT BKN STRATUS DECK ACROSS THE
DELTA REGION LATER THIS AFTERNOON./ALLEN/

&&

.PREV DISCUSSION... /ISSUED 352 AM CDT THU MAY 26 2011/

SHORT TERM...TODAY THROUGH SATURDAY...SCATTERED THUNDERSTORMS
WILL DEVELOP ONCE AGAIN DURING THE LATE MORNING/EARLY AFTERNOON OUT
AHEAD OF A WEAK COLD FRONT THAT WILL EXTEND ALONG THE NATCHEZ TRACE
BY LUNCHTIME. THE BEST CHANCES FOR THUNDERSTORMS WILL BE ALONG THE
I-59 CORRIDOR...BUT ISOLATED STORMS WILL BE POSSIBLE EAST OF I-55.
THE GFS INDICATES THAT ML CAPES WILL RANGE FROM 2000-2500 J/KG AND
WITH LAPSE RATES UP NEAR 7.0 C/KM SOME OF THESE STORMS COULD BE
STRONG TO SEVERE THIS AFTERNOON...MAINLY EAST OF A LINE FROM
COLUMBUS TO FOREST TO MONTICELLO WITH LARGE HAIL AND DAMAGING WINDS
BEING THE MAIN RISK. MOISTURE SHOULD BE SUFFICIENT DURING THE LATE
MORNING EARLY AFTERNOON HOURS WITH A 335K THETA-E RIDGE OVER THESE
AREAS ALONG WITH PWATS UP NEAR 1.6 INCHES. THE BEST MOISTURE SHIFTS
TO THE EAST OF THE AREA DURING THE MID-LATE AFTERNOON. THE UPPER
TROUGH WILL SHIFT TO THE EAST OF THE AREA EARLY THIS EVENING ALONG
WITH THE COLD FRONT WITH MUCH DRIER AIR FILTERING BEHIND IT.

PWATS WILL FALL BELOW AN INCH BY FRIDAY ACROSS ALL OF THE AREA WITH
HIGH PRESSURE RIDGING AT THE SURFACE AND ALOFT. STRONG UPPER RIDGING
WILL CONTINUE TO BUILD OVER THE AREA ON SATURDAY AND WITH WARMING
H925/H850 TEMPERATURES HIGHS WILL CLIMB TO AROUND 90. RAISED HIGH
TEMPS A TOUCH ABOVE GUIDANCE FOR TODAY AND TOMORROW ACROSS THE
AREA...BUT STUCK WITH GUIDANCE FOR TEMPS ON SATURDAY./15/

LONG TERM...SATURDAY NIGHT THROUGH THURSDAY...FOR THE MED
RANGE/LONG TERM...IF YOU LIKE SUMMER...THEN THE EXPECTED WEATHER
PATTERN IS FOR YOU. FOR THE SECOND HALF OF THE WEEKEND...A UPPER
RIDGE WILL BEGIN TO BUILD OVER THE EASTERN CONUS. THIS UPPER RIDGE
WILL CONTINUE TO BUILD AND AMPLIFY BY MID WEEK AND BECOME A WELL
DEFINED UPPER HIGH CENTER OVER THE CENTRAL CONUS WITH HEIGHTS 594-595
DM. THIS LOOKS TO BE A STOUT UPPER RIDGE WITH UPPER HEIGHT ANOMALIES
RUNNING 2.5 STANDARD DEVIATIONS ABV THE NORM. THIS WILL RESULT IS
LITTLE TO NO PRECIP CHANCES INTO NEXT WEEK AND TEMPS WARMING TO AT
LEAST THE 90-95 RANGE. VALUES COULD GET WARMER AND WILL HAVE TO SEE
HOW THE LOW LEVELS RESPOND BEFORE GOING WARMER THAN THE ALREADY WARM
GUID VALUES. /CME/
