AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
333 PM EDT SAT AUG 29 2015

.SHORT TERM /TONIGHT THROUGH SUNDAY NIGHT/...
THE SHORT TERM MODELS ARE IN GOOD AGREEMENT THROUGH THE PERIOD
KEEPING A MOIST AIRMASS IN PLACE. THE UPPER LEVEL LOW OVER THE
NORTHERN GULF WILL CONTINUE TO LIFT ACROSS SOUTH ALABAMA INTO
NORTHWEST GA BY SUNDAY EVENING AND NORTH OF THE FORECAST AREA
SUNDAY NIGHT. WEAK IMPULSES WILL CONTINUE TO LIFT ACROSS THE
FORECAST AREA AHEAD OF THE LOW. HIGH PRESSURE OVER THE CAROLINAS
WILL KEEP EASTERLY FLOW AT THE SURFACE. THIS WILL REINFORCE SOME
LOWER CLOUDS BY MORNING ACROSS THE AREA WITH MID LEVEL CEILINGS
EXPECTED ACROSS THE REGION. ALTHOUGH INSTABILITY WILL BE
MINIMAL...ISOLATED THUNDER WILL BE POSSIBLE AS THE IMPULSES LIFT
NORTH THROUGH TOMORROW. THE AREAS OF SHOWERS WILL CONTINUE
OVERNIGHT...WITH BEST CHANCES OVER WEST GA...BUT DO EXPECT SOME
LULLS. GUIDANCE TEMPERATURES ARE IN LINE AND HAVE TAKEN A BLEND OF
MAV/MET.

ATWELL

.LONG TERM /MONDAY THROUGH SATURDAY/...
NO MAJOR CHANGES TO THE ONGOING LONG TERM FORECAST.

THE REMNANTS OF ERIKA STILL EXPECTED TO IMPACT THE CWFA NEXT WEEK.
FOR NOW...THE SYSTEM WILL REMAIN A LOW PRESSURE TROUGH AS IT COMES
ONSHORE ACROSS THE FLORIDA PANHANDLE EARLY NEXT WEEK.

THE PERSISTENT SOUTHERLY FLOW ALOFT WILL BRING ABUNDANT MOISTURE
NORTHWARD FROM THE GULF OF MEXICO FOR MUCH OF NEXT WEEK...SO CHANCE
POPS STILL NEEDED EVERY DAY. IN ADDITION...AN UPPER TROUGH ACROSS
THE EASTERN HALF OF THE COUNTRY WILL HELP KEEP TEMPERATURES MOSTLY
IN THE 80S THROUGH THE PERIOD.

WIND SHEAR IN THE GULF IS A LITTLE WEAKER...SO SOME REGENERATION OF
ERIKA IS POSSIBLE.
