.DISCUSSION...
/ISSUED 844 PM CDT TUE JUL 7 2015/

WHILE A SYNOPTIC SCALE RIDGE CONTINUES TO SLOWLY SHIFT WEST ACROSS
THE SOUTHEAST, THE MAIN FOCUS FOR SHOWERS AND THUNDERSTORMS HAS ALSO
SHIFTED WEST ALONG A FRONTAL BOUNDARY AND SEVERAL MID-LEVEL SHORTWAVE
TROUGHS OVERRUNNING THE BOUNDARY. THOUGH A COUPLE OF ISOLATED
SHOWERS HAVE APPROACHED THE NW PORTIONS OF AL, THE REST OF THE
FORECAST AREA HAS REMAINED DRY WITH PRIMARILY HIGH CLOUDS AS THE
`IMPACT`. GIVEN THE CLOSE PROXIMITY OF SHOWERS AND THUNDERSTORMS OVER
CENTRAL/WESTERN TN AND HI RES MODEL DATA SHOWING A WEAK VORT MAX
(PERHAPS CONVECTIVE FEEDBACK) MOVING ACROSS NW AL, WILL KEEP ISOLATED
THUNDERSTORMS STAGGERED OVER THAT AREA. OTHERWISE, MADE SOME MINOR
TWEAKS TO THE TEMPERATURE AND DEWPOINT FORECAST TO ACCOUNT FOR THE
CURRENT TREND.

IN ADDITION, ADJUSTED THE SKY COVER FORECAST TO REFLECT THE HIGH
CIRRUS CANOPY FROM THUNDERSTORMS OVER THE MS/OH RIVER VALLEYS.
HOWEVER, WHERE SOME CLOUD CLEARING OCCURS, PATCHY FOG MAY DEVELOP
NEAR RIVERS, LAKES, AND LOW-LYING VALLEYS.
