AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE HUNTSVILLE AL
826 PM CDT TUE JUL 17 2012

.UPDATE...
EVENING UPDATE.

&&

.DISCUSSION...
TEMPERATURES ACROSS THE TENNESSEE VALLEY ARE CURRENTLY IN THE LOWER
TO MIDDLE 80S...WHICH IS RIGHT ON TRACK WITH THE HOURLY TEMPS AS OF
01Z. ISOLATED SHOWERS AND STORMS CONTINUE TO DEVELOP AND QUICKLY
FIZZLE OUT AS OUTFLOW BOUNDARIES ARE SPRAWLED ACROSS THE AREA IN THE
WAKE OF RECENTLY DISSIPATED CONVECTION. EXPECT THAT THIS TREND WILL
CONTINUE FOR A COUPLE MORE HOURS WITH A WEAK UPPER LOW TO THE SOUTH
AND EAST OF THE AREA...AND THE CURRENT FORECAST HAS THIS TREND
THROUGH MIDNIGHT...WHICH LOOKS FINE. AFTER MIDNIGHT...AMPLE MOISTURE
IN PLACE ALONG WITH CLEARING SKIES WILL LIKELY LEAD TO PATCHY FOG
DEVELOPMENT...WHICH IS ALSO INCLUDED IN THE CURRENT FCST...SO NO
CHANGES ARE NECESSARY WITH THIS UPDATE.

WILL FRESHEN WORDING IN ZONES AND RESEND THEM SHORTLY.

.AVIATION...
/ISSUED 627 PM CDT TUE JUL 17 2012/
FOR 00Z TAFS...
VFR CONDITIONS AT BOTH TERMINALS MAY TEMPORARILY DROP TO MVFR WITH
ISOLATED SHOWERS/STORMS IN THE VICINITY THROUGH 18/03Z.
OTHERWISE...A FEW CLOUDS AOA 5KFT MAY LINGER THROUGH THE NIGHT WITH
AT LEAST PATCHY FOG DEVELOPING BY DAYBREAK TOMORROW MORNING. VSBYS
MAY DIP BETWEEN 4-5SM BETWEEN 18/10-12Z...BUT WILL IMPROVE AS FOG
DISSIPATES BY 18/14Z. SHOWERS AND STORMS WILL DEVELOP AGAIN DURING
THE LATE MORNING/EARLY AFTERNOON HRS TOMORROW...LINGERING THROUGH THE
END OF THE TAF PERIOD.

12

&&

.PREV DISCUSSION...
/ISSUED 352 PM CDT TUE JUL 17 2012/
LATEST WATER VAPOR IMAGERY AND H5 RUC ANALYSIS INDICATE A CUT OFF
LOW NEAR NORTHERN CALIFORNIA...BROAD CYCLONIC FLOW NORTH OF THE
GREAT LAKES...AND A LARGE AREA OF RIDGING ACROSS MUCH OF THE
REMAINING CONUS. ACROSS NORTHERN FLORIDA/GEORGIA...A VORT MAX IS
SLOWLY PUSHING WESTWARD INTO THE SOUTHEAST STATES. THIS TUTT LOW HAS
AIDED THUNDERSTORM DEVELOPMENT ACROSS MUCH OF SOUTH ALABAMA AND
GEORGIA THIS AFTERNOON...BUT SO FAR...DEVELOPMENT ACROSS THE CWFA
HAS BEEN VERY LIMITED. WITHOUT ANY PRECIPITATION...TEMPERATURES HAVE
BEEN ABLE TO CLIMB VIRTUALLY UNIMPEDED /SAVE FOR A SCATTERED CU
FIELD/. THE 3PM TEMPERATURE FROM MSL WAS A TOASTY 97
DEGREES...HOWEVER THE AIR MIXED SUFFICIENTLY THERE TO KEEP THE HEAT
INDEX AT A BALMY 103.

FOR THIS EVENING...OPTED TO GO ON THE LOW SIDE FOR THUNDERSTORM
CHANCES GIVEN THE LIMITED DEVELOPMENT THUS FAR AND THE LACK OF
APPRECIABLE UPPER LEVEL SUPPORT. HOWEVER THERE ARE PLENTY OF LOW
LEVEL BOUNDARIES MOVING TOWARD THE AREA FROM NEARBY STORMS...AND
GIVEN THE WARM ATMOSPHERE...COULD STILL SEE DEVELOPMENT THROUGH
SUNSET. SOUNDINGS SUGGEST THE STRONGEST STORMS COULD BE CAPABLE OF
THE TYPICAL SUMMERTIME THREATS...GUSTY WINDS...FREQUENT LIGHTNING
AND LOCALLY HEAVY RAINFALL. AFTER THE THUNDERSTORM THREAT ENDS THIS
EVENING...THE ATMOSPHERE WILL REMAIN WARM AND MOIST...SO PATCHY FOG
IS EXPECTED TOWARD DAYBREAK IN THE FAVORED LOCATIONS. LOOK FOR
TEMPERATURES IN THE LOW 70S...WITH SLIGHTLY WARMER TEMPERATURES IN
THE HIGHER TERRAIN.

FOR TOMORROW AND THURSDAY...LOOK FOR DIURNALLY ENHANCED
THUNDERSTORMS BOTH DAYS WITH HIGHS IN THE LOW AND MIDDLE 90S FOR
MOST LOCATIONS. THE TUTT LOSES INTENSITY TOMORROW...BUT WITH A WEAK
APPROACHING LOW LEVEL WAVE...SCATTERED THUNDERSTORMS ARE STILL
EXPECTED TO DEVELOP BY LATE IN THE MORNING AS TEMPERATURES CLIMB.
CONVECTION WILL LINGER THROUGH THE EVENING...BEFORE DEVELOPING AGAIN
THURSDAY MORNING. EXPECTING SLIGHTLY GREATER COVERAGE ON THURSDAY AS
MOISTURE POOLS ACROSS THE AREA AHEAD OF AN APPROACHING WEAK FRONTAL
BOUNDARY. ANY OF THE STORMS ON BOTH WEDNESDAY AND THURSDAY WILL BE
CAPABLE OF GUSTY WINDS...FREQUENT LIGHTNING...AND LOCALLY HEAVY
RAINFALL.

THE HIGHEST RAINFALL CHANCES OF THE FORECAST WILL COME ON FRIDAY AS
THE SURFACE FRONT SAGS ACROSS THE AREA. WITH PWATS SURPASSING 2.0
INCHES AND SHEAR REMAINING WEAK...THE STRONGEST STORMS MAY PRODUCE
STRONG/DAMAGING WINDS ALONG WITH LOCALIZED FLASH FLOODING AND
FREQUENT LIGHTING. ALONG WITH THE HIGHER THUNDERSTORM
COVERAGE...LOOK FOR TEMPERATURES TO RUN A FEW DEGREES COOLER ON
FRIDAY AS COMPARED TO TODAY.

MODELS ADVERTISE THE FRONT STALLING ACROSS/NEAR CENTRAL ALABAMA FOR
MUCH OF THE WEEKEND AND INTO EARLY NEXT WEEK...SO HAVE SHOWN A
NORTH-SOUTH GRADIENT TO PRECIPITATION CHANCES FOR MUCH OF THE
PERIOD. THESE WILL BE DIURNALLY ENHANCED WITH TEMPERATURES IN THE
LOWER AND MIDDLE 90S EXPECTED.
