AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
717 AM EDT TUE JUL 14 2015

.PREV DISCUSSION... /ISSUED 338 AM EDT TUE JUL 14 2015/

SHORT TERM /TODAY THROUGH WEDNESDAY/...
MCS CURRENTLY ACROSS EASTERN INDIANA AND NORTHERN KY WILL CONTINUE
TO PUSH OFF TO THE SE INTO THE CAROLINAS EARLY THIS MORNING. THE HI-
RES MODELS ARE PROGGING THIS COMPLEX TO WEAKEN AS IS DROPS
SOUTH...BUT A FEW OF THE STORMS COULD BRUSH FAR NORTHEAST GA DURING
THE FIRST PART OF THE MORNING.

THE MAIN SHOW IS STILL PROGGED FOR THE EARLY EVENING AND OVERNIGHT
HOURS. UNTIL THEN...CONVECTION SHOULD REMAIN MOSTLY
UNORGANIZED...BUT POSSIBLY FOCUSING ALONG A LEE TROUGH SITUATED
ACROSS THE EASTERN AND SOUTHERN PORTIONS OF THE CWFA. POPS ACROSS
NORTHERN GA REMAIN LOW FOR MUCH OF THE DAY...WHILE SCT POPS ARE
NECESSARY ACROSS THE SOUTHERN HALF OF THE OUTLOOK AREA.

A SECOND MCS IS PROGGED TO DROP SOUTH IN THE FLOW LATER THIS
AFTERNOON AND BEGIN IMPACTING NORTHERN GA RIGHT BEFORE 00Z. THE
MODELS HAVE BEEN VERY CONSISTENT WITH AN MCS DEVELOPING/IMPACTING
THE CWFA...BUT HAVE CONTINUED TO STRUGGLE WITH THE TIMING OF THE
FEATURE. EVEN THE HI-RES MODELS TEND TO HAVE DIFFICULTY RESOLVING
THE TIMING OF THESE FEATURES. SINCE THE HRRR DOESN'T GO FAR
ENOUGH...HAVE RELIED ON THE WRF FOR GENERAL TIMING. ALSO...HAVE
PLACED LIKELY POPS WHERE THE MCS IS MOST LIKELY GOING TO
IMPACT...BUT THEY MAY HAVE TO BE ADJUSTED ONCE THE FEATURE DEVELOPS
AND BEGINS TO PROPAGATE.

THE POTENTIAL FOR SEVERE WEATHER WILL INCREASE AS THE EVE/OVERNIGHT
MCS AFFECTS THE AREA. MID LEVEL LAPSE RATES ARE PRETTY STEEP FOR
THIS TIME OF YEAR...PLUS SOME PRETTY DECENT SHEAR WILL ACCOMPANY THE
MCS. DAMAGING WIND GUSTS AND LARGE HAIL WILL CERTAINLY BE THE
PRIMARY MODES OF SEVERE WEATHER...BUT ISOLATED TORNADOES WILL ALSO
BE POSSIBLE WITH THE DECENT SHEAR VALUES.

THE POTENTIAL FOR SEVERE WEATHER WILL EXIST AGAIN ON WEDNESDAY. THE
SURFACE TROUGH SITUATED ACROSS THE EASTERN AND SOUTHERN PORTIONS OF
THE FORECAST AREA SHOULD PROVIDE THE MAIN FOCUS FOR ANY CONVECTIVE
ACTIVITY. WITH THE UNSTABLE AIRMASS IN PLACE AND A NICE INVERTED V
IN THE SOUNDINGS...DAMAGING WIND GUSTS WILL BE POSSIBLE WITHIN ANY
SEVERE THUNDERSTORMS THAT DEVELOP. ALSO...FORECAST SOUNDINGS ARE
SHOWING SOME STEEP MID LEVEL LAPSE RATES...SO WOULDN'T COMPLETELY
RULE OUT HAIL.

HAVE GONE AHEAD AND ISSUED ANOTHER HEAT ADVISORY FOR SOUTHERN
PORTIONS OF THE CWFA. HEAT INDICES AROUND 105 DEGREES WILL BE
LIKELY. THERE IS POTENTIAL FOR ANOTHER HEAT ADVISORY WITHIN THE SAME
AREA ON WEDNESDAY AFTERNOON.

NLISTEMAA

LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/...
WEAK COLD FRONT AND PREFRONTAL TROUGH WILL BE MOVING INTO/OVER THE
AREA WEDNESDAY NIGHT WITH THE MAIN UPPER TROUGH BEGINNING TO MOVE
OFFSHORE THE EAST COAST. HIGHEST POPS WILL BE SHIFTING TO CENTRAL GA
WHERE SOME POTENTIAL FOR SEVERE STORMS MAY LINGER DURING THE EVENING...
POSSIBLY THE OVERNIGHT HOURS.

OTHERWISE HIGH PRESSURE RIDGE ALOFT BUILDS SOME OVER THE AREA ON
THURSDAY WITH THE CENTER REMAINING TO THE WEST. THIS PATTERN CONTINUES
THROUGH THE WEEKEND WITH JUST SOME WEAKENING OF THE UPPER RIDGE ON MONDAY.
THIS WILL ALSO WEAKEN/DIMINISH THE NW FLOW ALOFT AND SHORT WAVE
POTENTIAL OVER THE CWA...ALLOWING FOR A VERY DIURNAL NATURE TO ANY
SHOWERS AND THUNDERSTORMS.

TEMPERATURES FOR THE MOST PART WILL BE A COUPLE TO A FEW DEGREES ABOVE
NORMAL DURING THE LONG TERM PERIOD.

BDL

.AVIATION...
12Z UPDATE...
SCT/ISOLD CONVECTION POSSIBLE DURING THE AFTERNOON...BUT POP
CHANCES ARE TOO LOW TO MENTION AT THE NORTHERN TERMINAL SITES. HI-
RES MODELS CONTINUE TO SHOW THE BEST CHANCE FOR THUNDERSTORMS IS
IN THE EARLY EVENING/OVERNIGHT HOURS AS A THUNDERSTORM COMPLEX
DROPS SOUTH FROM THE TN/OH VALLEYS.WENT A LITTLE WIDE WITH THE
PROB30 GROUP...BUT CURRENT INDICATIONS ARE THAT THE BEST TIME FOR
THUNDERSTORMS SHOULD BE 01Z TO 04Z. WINDS WILL REMAIN ON THE WEST
SIDE BUT FREQUENT GUSTS TO 15-20KT WILL BE POSSIBLE THIS AFTERNOON
AND TOMORROW.

//ATL CONFIDENCE...12Z UPDATE...
MED CONFIDENCE ON CONVECTION...HIGH CONFIDENCE REMAINING
ELEMENTS.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF NORTH AND
CENTRAL GEORGIA.

ISOLATED TO SCATTERED SEVERE THUNDERSTORMS ARE EXPECTED OVER NORTH
AND MUCH OF CENTRAL GEORGIA...THIS AFTERNOON AND TONIGHT.

WEATHER HAZARDS EXPECTED...

UPPER LEVEL DISTURBANCES WITHIN THE NORTHWEST FLOW ALOFT
WILL ALLOW FOR THUNDERSTORMS TO DEVELOP. SOME STORMS WILL BECOME
SEVERE WITH THE GREATEST THREAT OVER NORTH GEORGIA. DUE TO THE NATURE
OF THE DISTURBANCES ALOFT...2 ROUNDS OF SEVERE STORMS WILL BE
POSSIBLE...MOST SO FOR NORTH GEORGIA.

SEVERE THUNDERSTORMS WILL BE POSSIBLE ON WEDNESDAY FOR CENTRAL AND
PORTIONS OF NORTH GEORGIA WITH DAMAGING WINDS AND FREQUENT LIGHTNING
BEING THE PRIMARY HAZARDS. LARGE HAIL AND HEAVY RAINFALL WILL ALSO
BE POSSIBLE. THERE WILL BE A CHANCE OF THUNDERSTORMS FOR MAINLY
CENTRAL GEORGIA ON THURSDAY AND ACROSS THE AREA FRIDAY THROUGH MONDAY.

.SPOTTER INFORMATION STATEMENT...
