Area forecast discussion, Apr 30, 7:38 AM EDT, 5 hours 44 minutes before

AREA FORECAST DISCUSSION...UPDATED FOR AVIATION
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
738 AM EDT SAT APR 30 2016

.SHORT TERM /TODAY THROUGH SUNDAY/...
WEAK FRONT VICINITY OF NORTH GA TODAY SHOULD GRADUALLY PUSH NORTH
THROUGH TONIGHT AS A WARM FRONT. THIS COULD PROVIDE A FOCUS FOR
THUNDERSTORM DEVELOPMENT SO HAVE CONTINUED WITH THE BEST POPS FOR
NORTH WITH LOWER POPS CENTRAL. THE FORECAST AREA REMAINS UNDER A
MOIST AND UNSTABLE AIR MASS THROUGH THE PERIOD. FOCUS FOR
THUNDERSTORMS ON SUNDAY SEEMS NOT AS OBVIOUS...HOWEVER THE MODELS
HINT AT A WAVE CROSSING THE STATE TONIGHT AND SUNDAY. SO CHANCE POPS
LOOK OKAY FOR SUNDAY. THE MAIN SURFACE FRONT GRADUALLY WORKS ITS WAY
INTO THE MS RIVER VALLEY BY SUNDAY. MAV/MET TEMPS LOOK OKAY BUT
CIRRUS FROM LOWER MS VALLEY STORMS COULD AFFECT THE MAX TEMPERATURES
TODAY.

41

.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
PERSISTENT ACTIVE PATTERN AND MOISTURE ADVECTION WILL REMAIN
OVER THE STATE INTO THE EXTENDED PERIOD. EXPECT CHANCE TO GOOD
CHANCE POPS THROUGH MID TO LATE WEEK AS A SERIES OF DISTURBANCES
IMPACT THE REGION. INITIALLY LOW PRESSURE OVER THE OHIO VALLEY
WILL LIFT TO THE NE...LEAVING A BOUNDARY DRAPED ACROSS THE STATE.
MONDAY AND TUESDAY SHOWERS AND THUNDERSTORMS WILL BE FOCUSED
ACROSS PORTIONS OF THE STATE AS WEAK UPPER LEVEL ENERGY PULSES
INTERACT WITH THE BOUNDARY. BY MID WEEK...A DEEPENING CLOSED LOW
WILL DROP INTO THE ARKLATEX AREA EARLY WEDNESDAY AND SWEEP THROUGH
THE REGION WEDNESDAY INTO THURSDAY...WITH THE SURFACE FEATURE
STRENGTHENING OVER SOUTHERN GEORGIA AND THE CAROLINAS. FOR
NOW...POPS TAPER OFF QUICKLY INTO WEDNESDAY AFTERNOON AND
EVENING...AND THIS MAY BE A LITTLE OPTIMISTIC. UNCERTAINTY WITH
THE POSITION OF BEST POPS AND THE OVERALL ENVIRONMENTAL STABILITY
STILL EXIST...AND THE POTENTIAL FOR STRONG STORMS CANNOT BE RULED
OUT. UPSTREAM CONVECTION DEVELOPING ALONG THE NORTHERN GULF COAST
WILL STILL BE A BIG PLAYER IN HOW MUCH PRECIP IS RECEIVED ACROSS
THE AREA.

BEHIND THIS SYSTEM...HIGH PRESSURE MOVES INTO THE STATE...KEEPING
DRY AND COOLER CONDITIONS ACROSS THE AREA INTO MOTHERS DAY
WEEKEND.
