AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEMPHIS TN
406 PM CDT THU AUG 5 2010
.DISCUSSION...
DANGEROUS HEAT WAVE WILL END BRIEFLY FRIDAY AND SATURDAY...BEFORE
POSSIBLY RETURNING SUNDAY INTO NEXT WEEK.
HEAT AND RAIN CHANCES LATE THIS AFTERNOON THROUGH FRIDAY ARE THE
BIGGEST CONCERNS.
THE BIGGEST CHANGE TO THE PREVIOUS FORECAST WAS TO REMOVE FOUR
COUNTIES IN NORTHEAST ARKANSAS OUT OF THE EXCESSIVE HEAT
WARNING...RANDOLPH...LAWRENCE...CLAY...AND GREENE.
KEPT EXCESSIVE HEAT WARNING FOR MUCH OF THE AREA THROUGH 9 PM
EXCEPT THE COUNTIES ABOVE WHERE CONFIDENT HEAT INDEX VALUES WILL
NOT EXCEED 110 DEGREES. OTHER AREAS IN THE WARNING AFFECTED BY
SHOWERS AND STORMS MAY NOT REACH 110 DEGREES...BUT AREAL COVERAGE
OF COOLER AIR AND STORMS ARE NOT GREAT ENOUGH TO COMPLETELY RULE
OUT RAINFREE AREAS FROM REACHING HEAT INDEX VALUES OF 110 DEGREES.
THROUGH MIDNIGHT...SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS
CAN BE EXPECTED. APPEARS BEST COVERAGE WILL BE NORTH MISSISSIPPI
THROUGH 7 PM...BUT ALSO EXPECT NEW DEVELOPMENT FARTHER NORTH.
LATEST SATELLITE IMAGERY DEPICTED A CLOUD BOUNDARY FROM WYNNE
ARKANSAS TO HUNTINGDON TENNESSEE LINE WHICH MAY BE A GOOD FOCUS
FOR NEW DEVELOPMENT IN THE NEXT FEW HOURS. KEPT 30 TO 50 PERCENT
FOR RAIN CHANCES ACROSS THE ENTIRE AREA. A FEW STORMS MAY BE
STRONG TO SEVERE WITH ISOLATED DAMAGING WIND GUSTS UP 60 MPH...
FREQUENT LIGHTNING...AND LOCALLY HEAVY RAINFALL WHICH COULD CAUSE
LOCALIZED FLOODING AS THE AIR REMAINS VERY MOIST WITH PRECIPITABLE
WATER VALUES NEAR 2 INCHES AND UNSTABLE WITH SBCAPE 3000-5000
J/KG. CONVECTION SHOULD WEAKEN AFTER 9 PM WITH THE LOSS OF DAYTIME
HEATING.
LATE TONIGHT...A FEW LINGERING SHOWERS AND STORMS MAY BE OVER THE
AREA. UNDER PARTLY TO MOSTLY CLOUDY SKIES...LOWS SHOULD BE IN THE
70S...COOLER THAN PAST MORNINGS DUE TO SHALLOW COOLER AIR FROM
NEARBY SHOWERS AND STORMS. THINK CLOUD COVER WILL LIMIT FOG
POTENTIAL.
FRIDAY WILL NOT BE NEARLY AS HOT NORTH OF I-40. LOWERED
TEMPERATURES NORTH OF I-40 WHERE MORE CLOUD COVER WILL KEEP HIGHS
IN THE UPPER 80S AND LOWER 90S ON THE NORTH SIDE OF SHALLOW COLD
FRONT. KEPT RAIN CHANCES TIERED FROM 10 PERCENT NEAR MISSOURI
BOOTHEEL TO 50 PERCENT OVER NORTHEAST MISSISSIPPI WHERE BEST
HEATING WILL OCCUR TO TRIGGER SHOWERS AND THUNDERSTORMS. A FEW
STRONG STORMS ARE POSSIBLE SOUTH OF A HELENA ARKANSAS TO SAVANNAH
TENNESSEE WHERE INSTABILITY WILL BE HIGHEST.
A HEAT ADVISORY MAY BE NEEDED OVER PARTS OF NORTH MISSISSIPPI
FRIDAY AFTERNOON WHERE HIGHS IN THE 93 TO 98 RANGE AND DEWPOINTS
IN THE MID 70S SHOULD ALLOW FOR HEAT INDEX VALUES IN THE 105 TO
109 RANGE. WILL LET MIDNIGHT SHIFT MAKE FINAL DECISION ON ADVISORY...
DEPENDING ON HOW CONVECTION TONIGHT AFFECTS THE LOCAL AIRMASS ON
FRIDAY.
FRIDAY NIGHT THROUGH SATURDAY NIGHT...RAINFREE AND COOLER
CONDITIONS WILL PREVAIL. MUCH DRIER AIR WITH DEWPOINTS IN THE 60S
SHOULD MOVE INTO WEST TENNESSEE. 12Z MAVMOS HIGHS IN THE LOWER TO
MID 90S SEEMED REASONABLE.
SUNDAY THROUGH NEXT THURSDAY...EXCESSIVE HEAT MAY RETURN AS
MID/UPPER LEVEL RIDGE BUILDS OVER THE AREA. ACCEPTED 12Z MEXMOS
TEMPERATURES WITH HIGHS 97 TO 102 AND LOWS MAINLY IN THE 70S. WITH
HEAT INDEX VALUES INCREASING ABOVE 105 DEGREES...AND PERHAPS 110
DEGREES...HEAT ADVISORIES AND EXCESSIVE HEAT WARNINGS MAY BE NEEDED.
CHANCES FOR RAIN APPEAR TO BE TOO SLIM TOO MENTION...EXCEPT
PERHAPS THURSDAY.
MBS
&&
.AVIATION...
18Z TAF CYCLE
MOSTLY VFR CONDITIONS TODAY WITH THE OCCASIONAL MVFR REDUCTION DUE
TO TSRA IMPACTS. WINDS WILL BE LIGHT AND OUT OF THE SOUTHWEST
AHEAD OF APPROACHING COLD FRONT. STORM CHANCES REMAIN THROUGH THE
DAY FOR ALL TAF SITES ESPECIALLY DURING PEAK DAYTIME HEATING
HOURS.
THE COLD FRONT WILL CONTINUE PUSHING SOUTHWARD THIS AFTERNOON
ACROSS THE AREA AFFECTING JBR...MKL...AND MEM. WITH THIS FRONT
WINDS WILL SHIFT TO NORTH AND CEILINGS WILL BEGIN TO DROP BELOW VFR
CONDITIONS. THE COLD FRONT WILL STALL JUST NORTH OF TUP AND
PRODUCE LIGHT AND VARIABLE WINDS THROUGH THE OVERNIGHT HOURS.
