AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
255 PM CDT THU MAY 7 2009
.SHORT TERM...ANOTHER DAY OF STORMS IS ON TAP FOR THE ARKLAMISS
REGION. PLENTY OF MOISTURE EXISTS OVER THE CWFA THIS AFTERNOON WITH
DEWPOINTS IN THE LOWER 70S FOR MOST LOCATIONS. TEMPERATURES HAVE
BEEN WARMING WITH HIGHS TODAY GETTING TO THE MIDDLE TO UPPER 80S.
SOUNDINGS SHOW DECENT INSTABILITY OVER THE CWFA. THESE FEATURES WILL
COMBINE TO ALLOW FOR SHOWERS AND THUNDERSTORMS THIS AFTERNOON.
CURRENT RADAR IMAGERY IS SHOWING ISOLATED SHOWERS POPPING UP ACROSS
THE CWFA. THESE SHOULD INTENSIFY OVER THE NEXT FEW HOURS. THERE IS A
POSSIBILITY FOR STRONG TO SEVERE STORMS THIS AFTERNOON WITH DAMAGING
WINDS AND HAIL BEING THE PRIMARY CONCERN. ACTIVITY SHOULD BEGIN TO
DIMINISH THIS EVENING TO GIVE A QUIET NIGHT OVER THE ARKLAMISS
REGION AS WE LOSE HEATING.
THE OVERNIGHT HOURS SHOULD BE QUIET WITH SKIES THAT WILL BE TRYING
TO CLEAR. STRATUS WILL BEGIN TO DEVELOP DURING THE EARLY MORNING
HOURS ON FRIDAY. TEMPERATURES OVERNIGHT WILL STILL BE SOMEWHAT WARM
WITH UPPER 60S TO LOWER 70S EXPECTED. HAVE REMAINED PRETTY MUCH
WITH GUI FOR LOW TEMPERATURES TONIGHT.
FRIDAY SHOULD BE MUCH QUIETER TO GIVE THE ARKLAMISS REGION A NICE
BREAK FROM ACTIVITY. THE ATMOSPHERE IS EXPECTED TO BE A LITTLE
DRIER WITH DEWPOINTS IN THE 60S. THERE ALSO LOOKS TO BE A BETTER
CAP OVER THE REGION WITH WARMER LOW LEVEL TEMPERATURES. THIS SHOULD
KEEP THE AREA DRY DURING THE DAY AND THROUGH THE EVENING FRIDAY. ONE
THING TO NOTE FOR FRIDAY IS THAT A TIGHTENING PRESSURE GRADIENT IS
GOING TO GIVE GUSTY WINDS FOR PORTIONS OF THE ARKLAMISS REGION. THE
DELTA REGION AT LEAST SHOULD SEE WINDS OF 15 TO 25 MPH WITH HIGHER
GUSTS UP TO 30 MPH. THEREFORE A LAKE WIND ADVISORY HAS BEEN ISSUED
FOR THE DELTA REGION FROM AROUND 10 AM FRIDAY THROUGH 7 PM FRIDAY
EVENING.
FOR FRIDAY NIGHT AND ESPECIALLY INTO SATURDAY THERE WILL BE
A DISTURBANCE MOVING NORTH OF THE AREA THAT SHOULD BEGIN TO BRING
CONVECTION BACK TO THE CWFA. THIS SHOULD BEGIN TO AFFECT
NORTHWESTERN PORTIONS OF THE CWFA LATE FRIDAY NIGHT INTO EARLY
SATURDAY MORNING AS THE BOUNDARY BEGINS TO SINK SOUTH TOWARD THE
CWFA. BY SATURDAY THIS BOUNDARY IS EXPECTED TO MOVE SOUTH INTO THE
ARKLAMISS REGION TO BRING SHOWER AND THUNDERSTORM ACTIVITY TO AT
LEAST THE NORTHERN HALF OF THE CWFA. THE BOUNDARY IS EXPECTED TO
STALL OVER NORTH MISSISSIPPI MOVING INTO THE REMAINDER OF THE
WEEKEND. THIS SHOULD KEEP RAIN CHANCES OVER AT LEAST THE NORTHERN
HALF OF THE CWFA THROUGH THE WEEKEND.
THE REMAINDER OF THE FORECAST REMAINS UNCHANGED. APPLICABLE
PORTIONS OF THE PREVIOUS LONG TERM DISCUSSION FOLLOWS. /14/
.LONG TERM...NO BIG CHANGES WERE MADE TO THE FORECAST. GUIDANCE POPS
AND TEMPS WERE GOOD FOR THE MOST PART. MADE SOME SMALL ADJUSTMENTS TO
THE POPS...MAINLY TO LOWER VALUES ACROSS THE SOUTH THROUGH THE
WEEKEND.
WITH ZONAL FLOW ALOFT AND NOTHING TO REALLY PUSH THE BOUNDARY OUT OF
THE AREA...IT HANGS ACROSS NORTH MISSISSIPPI THROUGH MAYBE MIDDAY
MONDAY. CLOUDS AND RAIN WILL KEEP THE NORTHERN HALF OF THE CWA
COOL AND SOUTHERN HALF PRETTY WARM. HIGHS WILL BE NEAR 90 FOR AREAS
ALONG THE HIGHWAY 84 CORRIDOR SUNDAY. A SHORT WAVE MOVES ACROSS THE
UPPER MIDWEST MONDAY AND FINALLY PUSHES THE BOUNDARY SOUTH AND EAST.
THE TAIL END OF THE BOUNDARY SEEMS TO STALL ALONG THE COAST AND
EXTENDS BACK INTO THE ARKLATEX. HIGH PRESSURE DROPS INTO THE EAST
AND BRINGS SOME COOLER DRIER AIR. TEMPERATURES MAY FALL INTO THE
LOWER TO MID 50S BY TUESDAY MORNING. OTHERWISE...HIGH TEMPERATURES
WILL REMAIN ABOVE NORMAL. THE MODELS SHOW THE BOUNDARY REMAINING OVER
THE SOUTHWEST PORTIONS OF THE CWA AND EVENTUALLY SHIFTING EAST INTO
AREA BEFORE BEING PULLED OUT OF THE CWA. LEFT SLIGHT CHANCE VALUES IN
FOR TUESDAY AFTERNOON AND EVENING. DOES NOT LOOK MUCH INSTABILITY
WILL BE AVAILABLE WITH THE BOUNDARY AS IT EXITS THE AREA...SO KEPT
THUNDER IN THE AFTERNOON AND JUST RAIN IN THE EVENING. GUIDANCE CAME
IN WITH SOME SMALL VALUES FOR WEDNESDAY AND THURSDAY OPTED TO LEAVE
THE AREA DRY. THE RIDGE BUILDS INTO THE NORTHERN GULF LATE WEDNESDAY
AND MAINTAINS THROUGH THE END OF THE NEXT WEEK. LOOKING FOR THE RIDGE
TO KEEP THE AREA DRY FOR THE MOST PART. CAN NOT RULE OUT AN ISOLATED
SHOWER OR THUNDERSTORM...SO LEFT 10-15 PERCENT POP VALUES IN FOR
WEDNESDAY AND THURSDAY. RETURN FLOW SHOULD BRING PLENTY OF WARM AND
MOIST AIR INTO THE REGION...SO RAIN CHANCES MAY RETURN NEXT WEEKEND
WITH ANOTHER BOUNDARY APPROACHING FRIDAY.
&&
.AVIATION...SCT-BKN BASES FROM 2-4 THOUSAND FEET WILL CONTINUE
THROUGH THE AFTERNOON WITH BKN DECKS ABOVE IN DEEP MOISTURE IN PLACE
ACROSS THE REGION. SCT SHOWERS/TSTMS WILL CONTINUE THROUGH THE
AFTERNOON WITH THE POTENTIAL FOR ISOLATED SEVERE STORMS WITH
DAMAGING WIND AND LARGE HAIL. SHOWERS AND THUNDERSTORMS WILL
DECREASE IN COVERAGE BY 7 PM WITH ACTIVITY ENDING ACROSS THE REGION
AROUND 10 PM. WIDESPREAD IFR CIGS WILL REDEVELOP AFTER MIDNIGHT WITH
GENERALLY OVC CIGS BELOW 1000 FT AND AREAS OF MVFR VSBYS IN FOG FROM
3-5MILES. VSBYS WILL CLEAR AND CIGS LIFT TO VFR BY MID MORNING WITH
SCT...LOCALLY BKN CLOUDS...ABOVE 4 THOUSAND FEET. GUSTY SOUTHWEST
WIND WILL DEVELOP DURING THE AFTERNOON. WIND SPEEDS WILL BE HIGHEST
OVER THE MS DELTA REGION WITH SUSTAINED WIND SPEEDS FROM 15 TO 25
MPH WITH HIGHER GUSTS.
