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.
