AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
326 PM CDT MON JUN 7 2010

.DISCUSSION...SHORT TERM(TONIGHT THROUGH WEDNESDAY) ISOLATED SHRA/
TSRA FORMING NEAR THE STALLED FRONTAL BOUNDARY THAT EXTENDED FROM
THE MS COAST-KSHV LINE. STORMS ATTEMPTING TO DRIFT NWD BUT RUNNING
INTO MUCH DRIER REGIME SO NOT EXPECTING MUCH ADDITIONAL COVERAGE
THROUGH THE EVENING HOURS. MEANWHILE...A 1018MB SURFACE HIGH CENTER
MOVING FROM NERN MS ACROSS THE TN VALLEY TONIGHT. TONIGHT WILL SEE OUR
MOST PLEASANT WEATHER CONDITIONS FOR THIS WEEK AS LOWS HEAD INTO THE
MID 60S ERN MS TO AROUND 70F IN NERN LA.  A STRAY STRONG TSRA MAY
BE SEEN BRIEFLY IN OUR SRN MOST LA PARISHES LATE THIS AFTERNOON BUT
WILL NOT MENTION IN HWOJAN SINCE PROBABILITIES SO LOW.

THE UPSTREAM MCS DISSIPATED IN AR WITH MINIMAL CLOUD DEBRIS DRIFTING
INTO OUR NWRN CWFA. OTHER THAN A FEW CIRRUS...EXPECT MOSTLY CLEAR
OVERNIGHT SKIES WITH TEMPS DROPPING OUT RATHER QUICKLY. THE FRONT
SHOULD BEGIN EDGING NWD SLOWLY LATE TONIGHT AND IT COULD REACH NEAR A
KHBG TO KHEZ TO KELD LINE TOWARD MORNING. THE SERN PART OF THE FRONT
SHOULD BUDGE VERY LITTLE WHILE THE NWRN PORTION OF THE BOUNDARY IS
PROGGED TO LIFT MORE QUICKLY INTO OUR DELTA COUNTIES TUESDAY MORNING
WITH THE HUMID AIR MASS RETURNING TO MUCH OF THE REGION W OF I-55 FOR
TUESDAY AFTERNOON. THIS WILL BRING HEAT INDEXES BACK INTO THE 100F TO
105F RANGE FOR THOSE LOCATIONS WHILE ERN MS REMAINS MORE TOLERABLE
FOR A SECOND DAY. AFTERNOON POPS SHOULD HOLD IN THE ISOLATED CATEGORY
UNTIL WEDNESDAY WHEN THE MID LEVEL RIDGE WEAKENS SOMEWHAT ALLOWING A
SRN TX CUTOFF LOW TO DRIFT TOWARD THE ARKLATEX AND OZARKS.

FOR TUESDAY NIGHT...EXPECT THE FRONT TO CONTINUE PIVOTING CLOCKWISE
AND MOVING SLOWLY EWD TO A POSITION ROUGHLY ALONG HIGHWAY 45 BY EARLY
WEDNESDAY. THE ENTIRE CWFA SHOULD BE BACK IN THE TROPICAL JUICE WITH
PWATS BACK NEAR 2 INCHES FOR WEDNESDAY AFTERNOON. WILL HAVE TO WATCH
THE HEAT INDEX FACTOR HEADING THROUGH THE SECOND HALF OF THE WEEK AS
LOW TEMPS SHOULD BE CREEPING CLOSER TO THE 73-75F RANGE AND THOSE
AFTERNOON INDICES PUSH 105F. /40/

&&

PREV DISCUSSION...LONG TERM(THURSDAY THROUGH MONDAY)...THE BERMUDA
RIDGE WILL BE FIRMLY IN PLACE ACROSS THE SOUTHEAST CONUS...WITH VERY
LITTLE CHANGE IN THE PATTERN EXPECTED THROUGH THE BEGINNING OF NEXT
WEEK. 500MB HEIGHTS WILL BE RUNNING ABOVE 590DM THROUGH THE PERIOD...
CONDUCIVE TO ABOVE NORMAL TEMPERATURES FOR THIS TIME OF YEAR.
AFTERNOON HIGHS WILL CONSISTENTLY RISE INTO THE LOW-MID 90S...AND
OVERNIGHT LOWS WILL STRUGGLE TO GET NEAR/BELOW THE 70 DEGREE MARK.
DEW POINTS IN THE AFTERNOONS WILL MIX INTO THE UPPER 60S/LOW 70S EACH
AFTERNOON...AND COUPLED WITH THE WARM SURFACE TEMPERATURES WILL
PROVIDE PLENTY OF DIURNAL INSTABILITY FOR AFTERNOON SHOWER AND
THUNDERSTORM DEVELOPMENT.

A WEAK COLD FRONT WILL APPROACH NORTHERN MS ON WED AFTERNOON...AND
LOOKS TO STALL NORTH OF THE CWA BEFORE WAVING BACK TO THE NORTH ON
THURS. THE BOUNDARY PROXIMITY WILL KEEP SHOWER/THUNDERSTORM CHANCES
GOING NORTH OF I-20 WED NIGHT. A CUT-OFF UPPER LOW WILL PASS TO OUR
WEST THURS PROVIDING SOME ADDITIONAL SYNOPTIC LIFT TO KEEP
SHOWER/THUNDERSTORM CHANCES GOING INTO THURSDAY NIGHT AS WELL. SOME
OF THE GFS CONVECTIVE PARAMETERS/VERTICAL TOTALS 27C+...STEEP SFC-
750MB LAPSE RATES- INVERTED V SOUNDING/LOOK FAVORABLE FOR MICROBURSTS
HOWEVER THE SAME PARAMETERS LOOKED FAVORABLE FOR DIFFERENT DAYS LAST
NIGHT SO CONFIDENCE IN THE SPECIFICS IS LOW.

GFS MOS HIGHS/LOWS SEEMED VERY REASONABLE AND ONLY MADE A FEW
ADJUSTMENTS TOWARD GFS ENSEMBLE GUIDANCE. THE WARM TEMPERATURES
COUPLED WITH THE ABUNDANT SURFACE MOISTURE WILL KEEP HEAT INDICES
EACH AFTERNOON NEAR 100 DEGREES THROUGH THE WEEK. /BK/

&&

.AVIATION...
DRIER AIR CONTINUES IN PLACE OVER OUR NRN AND ERN CWFA. THIS SHOULD
KEEP VFR CONDITIONS PREVAILING AT MOST SPOTS. THERE COULD BE A STRAY
STORM DURING EARLY EVENING FARTHER TO THE SW WHERE A STALLED FRONTAL
BOUNDARY RESIDES. AT THIS TIME LOOKS LIKE MOST ALL TAF SITES WILL NOT
BE AFFECTED AND KHEZ WOULD BE MOST AFFECTED BUT WILL LEAVE VCTS IN
THE KHBG TAF FOR THE SMALL POSSIBILITY OF A STORM SNEAKING IN WITH A
LATE SEA BREEZE IN THAT AREA. IN ANY STORM...VIS AND CEILINGS COULD
BE REDUCED TO MVFR TO IFR STATUS. OTHERWISE...VFR CONDITIONS TO
CONTINUE THROUGH TUESDAY. WINDS WILL REMAIN GENERALLY FROM THE E TO
SE AROUND 5-8KTS OR LESS BECOME MORE SLY LATE TUESDAY. /28/
