AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE JACKSON MS
920 AM CDT FRI JUL 4 2008

.UPDATE...LATEST SATELLITE IMAGERY SHOWS NORTHWEST FLOW REGIME WITH A
SERIES OF SHORT WAVES. JET MAXES ASSOCIATED WITH THE SHORTWAVES WERE
STAYING NORTH OF THE REGION. A COMPLEX WAS NOTED OVER NORTHERN
ARKANSAS...WHICH HAD SENT AN OUTFLOW BOUNDARY INTO THE NORTHWEST DELTA
REGION. ISOLATED SHOWERS AND THUNDERSTORMS ARE EXPECTED TO DEVELOP ACROSS
THE NORTH FOR THIS AFTERNOON. ALSO TO THE SOUTH ISOLATED SHOWERS AND THUNDERSTORMS
WERE OFF THE COAST. EXPECT SOME SEA BREEZE ACTIVITY TO DEVELOP
ACROSS THE SOUTH...BUT LOW LEVEL SOUTHWEST FLOW MAY LIMIT HOW FAR
INLAND IT GOES. DO NOT EXPECT ANYTHING IN THE SOUTH UNTIL ABOUT MID
AFTERNOON. AREA SOUNDINGS THIS MORNING SHOWS THAT WE HAVE LOST OUR
INVERSION WITH SOME LIMITED LAPSE RATES. PRECIPITABLE WATER HAS
INCREASED FROM 1.2 TO AROUND 1.4 INCHES...WHICH IS TOO DRY FOR ANY
MORNING ACTIVITY. PRECIPITABLE WATER AT KLIX WAS NEAR 1.8 INCHES.
OUR SOUNDING SHOWED LIGHT WESTERLY FLOW IN THE LOW TO MID
LEVELS...WHICH WILL CONTINUE OUR 1.4 INCHES OF PRECIPITABLE WATER
FROM THE WEST. RUC AND SHORT RANGE MODELS SHOWS THE BEST COVERAGE IN
THE NORTH AND SOUTH FOR THIS AFTERNOON. THIS WAS ALSO AGREED WITH BY
THE LOCAL WRF ENSEMBLES. STILL EXPECT PLENTY OF SUNSHINE TO WARM
TEMPS QUICKLY INTO THE LOWER 90S FOR THIS AFTERNOON. VERTICAL AND
CROSS TOTALS WILL ONLY BE INTHE LOWER TO MIDDLE 20S...BUT AN
ISOLATED STRONG STORM IN THE NORTH...MAINLY AND ALONG AND NORTH OF
THE HIGHWAY 82 CORRIDOR WILL NOT BE OUT OF THE QUESTION. SO WITH
THIS IN MIND WILL TAKE OUT MORNING POPS AND WEATHER GRIDS AND KEEP
CURRENT POPS FOR THIS AFTERNOON. KEEP FORECAST AS WRITTEN WITH THE
BEST POPS NORTH AND SOUTH WITH HIGHS IN THE LOWER 90S./17/

&&
.AVIATION...DISCUSSION COMING AT 18Z.
&&

./PREVIOUS DISCUSSION...330 AM CDT FRI JUL 4 2008/

.SHORT TERM...TODAY THROUGH SATURDAY...STILL LOOKING FOR BETTER RAIN
CHANCES ACROSS MORE OF OUR AREA GOING INTO THE WEEKEND. LATEST
SURFACE ANALYSIS PLACES A QUASI-STATIONARY FRONTAL BOUNDARY ACROSS
THE OZARKS AND THE MISSOURI BOOTHEEL. EARLIER CONVECTION ALONG THIS
BOUNDARY HAS SENT AN OUTFLOW BOUNDARY SOUTH TOWARD OUR CWA AND
ISOLATED SHOWERS AND THUNDERSTORMS WERE STILL DEVELOPING JUST
NORTHWEST OF BOLIVAR COUNTY. THIS ACTIVITY MAY MOVE ACROSS OUR
NORTHERN TIER ZONES LATER THIS MORNING. OTHERWISE...BEST CHANCES FOR
RAIN WILL OCCUR LATER THIS AFTERNOON AND EVENING DUE TO HEATING.
MOISTURE WILL GRADUALLY INCREASE TODAY AND SATURDAY. LAST TWO JAN
SOUNDINGS HAD A PW NEAR AN INCH AND A QUARTER. MOST SITES WERE
REPORTING DEW POINTS IN THE MID TO UPPER 60S EARLY THIS MORNING.
WITH SURFACE RIDGING JUST OFF THE GULF COAST LOW LEVEL SOUTH TO
SOUTHWEST FLOW WILL WORK TO INCREASE LOW LEVEL MOISTURE. SURFACE DEW
POINTS WILL BE BACK IN THE LOWER 70S SATURDAY AND PWS WILL BE BACK
ABOVE AN INCH AND A HALF. FOR TODAY...BEST RAIN CHANCES WILL BE IN
THE SOUTH WITH THE SEA BREEZE AND IN OUR NORTH DUE TO THE CLOSE
PROXIMITY OF THE FRONTAL BOUNDARY. THE MAV GUIDANCE POPS WERE A
LITTLE TOO LOW FOR THE NORTHERN HALF OF THE CWFA TODAY AND AMONG THE
LOWEST ENSEMBLE MEMBERS...SO HAVE GONE ABOVE GUIDANCE POPS TO
INCLUDE ISOLATED WORDING AT LEAST IN OUR CENTRAL ZONES. LOCAL WRF
ENSEMBLE RUNS DID SHOW ISOLATED CONVECTION ACROSS MOST OF THE AREA
TODAY AS WELL. MODELS STILL PROG SEVERAL SHORTWAVES DEEPENING THE
UPPER TROUGH OVER THE NORTHEAST CONUS IN THE SHORT TERM. THIS WILL
HELP THE FRONTAL BOUNDARY SAG CLOSER TO OUR CWFA THROUGH SATURDAY.
THE NAM BRINGS THE BOUNDARY THE FARTHEST SOUTH INTO OUR CWA SATURDAY
BUT THE BOUNDARY IS EXPECTED TO STALL ALONG AND NORTH OF HIGHWAY 82
BEFORE DISSIPATING SUNDAY. MUCH OF THE ACTIVITY WILL DISSIPATE THIS
EVENING IN THE SOUTH BUT ACTIVITY IS EXPECTED TO LINGER THROUGH THE
NIGHT IN THE NORTH. SCATTERED CONVECTION IS EXPECTED AREAWIDE
SATURDAY. INCREASED CLOUDS AND RAIN CHANCES SHOULD HOLD MOST SITES
IN THE UPPER 80S SATURDAY BUT AFTERNOON HIGHS SHOULD TOP OUT IN THE
LOWER 90S THIS AFTERNOON. OVERNIGHT LOWS WILL BE CLOSE TO NORMAL
TONIGHT. GUIDANCE TEMPS WERE CLOSE AND MAV GUIDANCE WAS GENERALLY
ACCEPTED. /22/

.LONG TERM...SATURDAY NIGHT THROUGH FRIDAY...THE AREA WILL CONTINUE
TO BE UNDER NORTHWESTERLY FLOW ALOFT THROUGH THE WEEKEND UNTIL THE
FLOW BECOMES LESS AMPLIFIED BY THE BEGINNING OF THE WORK WEEK.
SEVERAL IMPULSES ARE EXPECTED TO MOVE THROUGH THE FLOW TOWARD THE
AREA DURING THE LONG TERM PERIOD.  THE BOUNDARY COMBINED WITH DECENT
MOISTURE AND INSTABILITY WILL KEEP SHOWER AND THUNDERSTORM ACTIVITY
LINGERING OVER THE ARKLAMISS REGION INTO AT LEAST SATURDAY EVENING
WITH SOME ISOLATED ACTIVITY POSSIBLE DURING THE OVERNIGHT HOURS. THE
REMNANTS OF THE BOUNDARY WILL AGAIN COMBINE WITH DECENT MOISTURE OF
PWATS APPROACHING 1.9 INCHES TO GIVE ANOTHER DECENT CHANCE FOR RAIN
FOR MUCH OF THE REGION.  THE BOUNDARY WILL BEGIN TO WASH OUT OVER
THE CWFA BY SOUTHERLY FLOW ON SUNDAY AND INTO THE BEGINNING OF THE
WORK WEEK. FOR THE WORK WEEK ACTIVITY SHOULD BECOME MORE TYPICAL OF
SUMMERTIME WITH MOST OF THE CONVECTION IN THE AFTERNOON BEING A
RESULT OF THE SEA BREEZE.  OVERALL HAVE REMAINED RATHER CLOSE TO GUI
POPS THROUGH THE LONG TERM AND FOR AT LEAST THE WORK WEEK HAVE SHOWN
A DIURNAL TREND TO CONVECTION.

TEMPERATURES THROUGH THE EXTENDED PERIOD WILL CONTINUE TO BE NEAR
CLIMATOLOGY WITH LOWER 90S FOR HIGHS AND LOWER 70S FOR LOWS EXPECTED
FOR THE ARKLAMISS REGION.  ENSEMBLE GUI IS IN DECENT AGREEMENT FOR
THE REGION WITH TEMPERATURES.  HAVE REMAINED WITH GUI THROUGH THE
LONG TERM FOR TEMPERATURES. /14/
