AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE HUNTSVILLE AL
616 PM CDT MON JUL 16 2012

.UPDATE...
FOR 00Z TAFS

&&

.DISCUSSION...
/ISSUED 249 PM CDT MON JUL 16 2012/
LATEST WATER VAPOR IMAGERY AND H5 RUC ANALYSIS INDICATE A CLOSED LOW
ACROSS THE PACIFIC NORTHWEST...WITH BROAD ANTICYCLONIC FLOW ACROSS
THE REMAINDER OF THE NORTHERN CONUS. IN THE SOUTHEAST...MID
LEVEL FLOW IS VERY ILL-DEFINED...SAVE FOR A RETROGRADING SHORTWAVE
TROUGH NEARING THE GEORGIA COASTLINE. ASSOCIATED WITH A SHORTWAVE
DEPARTING FROM THE NORTHEAST STATES...MOISTURE NEAR THE APPALACHIANS
LEAD TO MORNING CONVECTIVE DEVELOPMENT...WITH SCATTERED CONVECTION
ONGOING ACROSS THE CWFA. ITS ANOTHER HOT AND HUMID DAY...WITH
TEMPERATURES AS HIGH AS THE MIDDLE 90S AND DEWPOINTS IN THE UPPER
60S AND LOW 70S.

THE CONVECTION SHOULD DISSIPATE THIS EVENING...AND H5 FLOW
SUGGESTS THE GREATEST COVERAGE OF STORMS WILL BE SOUTH AND EAST OF
HERE. WITH AMPLE LOW LEVEL MOISTURE AND LACK OF APPRECIABLE SURFACE
FLOW...EXPECTING ANOTHER NIGHT OF PATCHY FOG DEVELOPMENT. SCOTTSBORO
REPORTED VISIBILITY AS LOW AS 1/4 SM...AND THE EVENING SHIFT WILL
NEED TO PAY CLOSE ATTENTION TO SEE IF THIS TREND IS AGAIN EXPECTED
TONIGHT. OTHERWISE...LOOK FOR LOWS IN THE UPPER 60S TO LOW
70S...MUCH LIKE WE HAVE SEEN THE LAST SEVERAL NIGHTS.

FOR TOMORROW...LOOK FOR ANOTHER DAY OF DIURNALLY DRIVEN SHOWERS AND
THUNDERSTORMS. ANY FOG THAT LINGERS PAST THE MORNING COMMUTE WILL
QUICKLY DISSIPATE...AND TEMPERATURES WILL ROCKET INTO THE UPPER 80S
AND LOW 90S BY NOON. IN FACT...BY THE AFTERNOON HOURS...HEAT INDEX
VALUES WILL BE IN THE LOW TRIPLE DIGITS ACROSS MUCH OF THE AREA. IN
THIS WARM AND UNSTABLE ATMOSPHERE...SCATTERED SHOWERS ARE POSSIBLE
ANYWHERE ACROSS THE CWFA...HOWEVER THEY SHOULD BE MOST CONCENTRATED IN
THE SOUTHEAST...WHERE THE RICHEST MOISTURE WILL BE CONCENTRATED AS
THE UPPER WAVE APPROACHES THE AREA. TEMPERATURES SHOULD BE A DEGREE
OR SO WARMER THAN TODAY...WITH HIGHS IN THE LOW AND MIDDLE 90S.
TOMORROW NIGHT WILL BE SIMILAR TO TONIGHT...WITH THUNDERSTORMS
DISSIPATING IN THE EVENING...AND PATCHY FOG DEVELOPING AFTER
MIDNIGHT. LOWS WILL ONCE AGAIN BE IN THE LOWER 70S.

THE CONVECTION ON WEDNESDAY WILL AGAIN BY DIURNALLY
MAXIMIZED...AIDED BY THE REMAINS OF THE RETROGRADING SHORTWAVE. BY
THURSDAY...LOOK FOR SLIGHTLY GREATER SHOWER AND THUNDERSTORM
ACTIVITY AS MOISTURE POOLS OVER THE AREA AND H5 FLOW BECOMES
NORTHWESTERLY AHEAD OF A BUILDING RIDGE OVER THE CENTRAL PLAINS.

THE HIGHER THUNDERSTORM CHANCES WILL CONTINUE ON FRIDAY AS A
SHORTWAVE TROUGH AND TRAILING COLD FRONT APPROACH THE AREA.
ULTIMATELY...THE MAIN SHORTWAVE WILL STAY NORTHEAST OF THE
CWFA...HOWEVER A RELATIVE MAXIMUM IN MID LEVEL WINDS AND THE HIGH
LOW LEVEL MOISTURE WILL CONTRIBUTE TO GREATER STORM COVERAGE...ALONG
WITH AN ENHANCED THREAT OF STRONG GUSTY WINDS...FREQUENT
LIGHTING...AND LOCALLY HEAVY RAINFALL.

THUNDERSTORM CHANCES WILL CONTINUE THROUGH THE WEEKEND...WITH
SEASONABLE TEMPERATURES IN THE LOW AND MIDDLE 90S FOR HIGHS...AND
LOWS IN THE LOW 70S.

JLL

.AVIATION...
FOR 00Z TAFS...

CLUSTERS OF THUNDERSTORMS WILL CONTINUE THRU 01-02Z. THE STRONGER
CLUSTER OF STORMS JUST N/NE OF KHSV WILL PRODUCE GUSTY OUTFLOW
WINDS...LIGHTNING AND +RA IN THE AREA. THE CELL JUST EAST OF KMSL IS
NOT AS INTENSE...BUT WILL MAINTAIN A VCTS THRU 01Z AT THIS LOCATION.
OTRW...PREVAILING VFR IS XPCTD TNGT INTO TUE...ALTHOUGH SOME PATCHY
BR MAY OCCUR LATE TNGT AND EARLY TUE...SO HAVE MAINTAINED TEMPO MVFR
DUE TO BR FROM 09-13Z.
