Area forecast discussion, Apr 10, 3:42 PM EDT, 1 hour 42 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
342 PM EDT FRI APR 10 2015

.SHORT TERM /TONIGHT THROUGH SATURDAY NIGHT/...
DRIER AIRMASS POISED TO ENTER THE NORTHWEST CORNER OF THE STATE AT
THIS TIME...HOWEVER AMPLE MOISTURE REMAINS IN PLACE AHEAD OF THE
FRONT AND TEMPERATURES ACROSS NORTH GEORGIA HAVE SEEN AT LEAST A BIT
OF A RECOVERY FROM EARLIER PRECIPITATION. BETTER CHANCES FOR THUNDER
THE REST OF THE AFTERNOON AND INTO THE EVENING REMAIN ACROSS CENTRAL
GEORGIA WHERE INSTABILITY HAS MANAGED TO REACH MODERATE LEVELS.
SBCAPE 1000-1500J/KG WITH MUCAPE 1000-2000J/KG ACROSS CENTRAL
GEORGIA IS MORE THAN AMPLE FOR A FEW STRONG TO MARGINALLY SEVERE
STORMS. SHEAR REMAINS WEAK BUT NOT ALTOGETHER LACKING...AND I DO NOT
ANTICIPATE ANY WIDESPREAD TORNADO THREAT. INSTABILITY EBBS SOMEWHAT
ACROSS CENTRAL GEORGIA OVERNIGHT AND ACTIVITY ALONG AND AHEAD OF THE
FRONT IS EXPECTED TO WEAKEN AND BECOME LESS WIDESPREAD THROUGH THAT
PERIOD. FRONT WASHES OUT ALONG OR SOUTH OF THE FORECAST AREA
SATURDAY WITH DIMINISHING PRECIPITATION CHANCES CONFINED TO THE
EXTREME SOUTHERN FRINGES OF THE AREA. DRY CONDITIONS EXPECTED
AREAWIDE BY LATE IN THE DAY SATURDAY THROUGH SATURDAY NIGHT AS
RELATIVE DRY HIGH PRESSURE BUILDS INTO THE STATE.

20

.LONG TERM /SUNDAY THROUGH FRIDAY/...
STILL SOME DISCREPANCIES BETWEEN THE ECMWF AND GFS IN THE LONG
TERM. ECMWF LIFTS THE MOISTURE BACK NORTH ON SUNDAY WHILE THE GFS
KEEPS IT SOUTH OF THE CWA. HAVE COMPROMISED IN THE MIDDLE WITH
PUSHING SOME PRECIP BACK INTO THE SOUTHERN PORTIONS OF CENTRAL
GEORGIA. BY MONDAY THOUGH...AN UPPER LEVEL LOW TRACKS ACROSS TX
AND THE FLOW ACROSS THE SE BECOMES SW...WITH PLENTY OF GULF
MOISTURE BEING PUMPED INTO THE CWA. THERE ARE A FEW SHORTWAVES IN
THE FLOW THAT MOVE THROUGH EARLY IN THE WEEK AND THIS IS ONE OF
THE TIMES THE MODELS ARE ACTUALLY IN AGREEMENT WITH WIDESPREAD
SHOWERS AND THUNDERSTORMS THROUGH MID WEEK. DISCREPANCIES RETURN
MORE FOR LATE IN THE WEEK WITH THE GFS MUCH QUICKER TO CLEAR OUT
THE LATE WEEK FRONT THAN THE ECMWF. FOR NOW...HAVE TRENDED TOWARDS
THE ECMWF WITH LEAVING CHANCE POPS IN THE FORECAST.

.AVIATION...
18Z UPDATE...

WIDE MIXTURE OF IFR TO VFR CONDITIONS CONTINUE ACROSS THE FORECAST
AREA AT THIS TIME. I EXPECT MVFR CONDITIONS TO PREDOMINATE THROUGH
AROUND 02-06Z ACROSS THE NORTH AND THROUGH 12Z ACROSS THE SOUTH. VFR
CONDITIONS EXPECTED AT ALL LOCATIONS BY 12-14Z SATURDAY. SCATTERED
SHOWERS AND ISOLATED TO SCATTERED THUNDERSTORMS THROUGH 00Z ACROSS
THE NORTH WITH SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS
THROUGH 04Z ACROSS THE SOUTH. ISOLATED SHOWERS AND THUNDERSTORMS ARE
LIKELY TO LINGER ACROSS THE EXTREME SOUTHERN END OF THE FORECAST
AREA PAST 12Z. SOUTHWEST TO WEST WINDS 6-12KTS...BECOMING MORE
NORTHWESTERLY BY 00Z. WIND SPEEDS DIMINISH SOME OVERNIGHT...BECOMING
GENERALLY 6KT OR LESS MOST AREAS.
