AREA FORECAST DISCUSSION...UPDATE
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
630 PM EDT FRI MAR 27 2015

.EARLY EVENING UPDATE...
STRONG UPPER TROUGH WITH ABUNDANT VORT MAX ENERGY IS APPROACHING THE
STATE AND CURRENTLY SPREADING ABUNDANT MID LEVEL CLOUDINESS INTO
NORTH AND WEST CENTRAL GA. RADAR SHOWS SOME LIGHT RETURNS IN NORTH
AL & FAR NW GA... SO CANNOT RULE OUT A FEW SPRINKLES OF LIGHT RAIN
THROUGH THE EVENING AS THE UPPER TROUGH AXIS MOVES ACROSS THE STATE.
HAVE UPDATED ZONES TO SPREAD CLOUDS A BIT FURTHER SOUTH INTO PARTS
OF CENTRAL GA THIS EVENING AND ADDING WORDING FOR A SLIGHT CHANCE OF
LIGHT RAIN FOR MOST OF NORTH GA THROUGH THE EVENING. THE CLOUDS AND
WINDS MAY HINDER SOME AREAS FROM REACHING FREEZING TONIGHT... BUT
TOO EARLY TO TWEAK THAT JUST YET AS CLOUDS ARE EXPECTED TO SCATTER
BY MORNING WITH PLENTY OF COLD AIR ADVECTION STILL ON TAP FOR
TONIGHT. WILL CONTINUE TO MONITOR THINGS CLOSELY... BUT HOLDING ONTO
THE FREEZE WARNING AS POSTED FOR NOW. /39


.SHORT TERM /TONIGHT THROUGH SATURDAY NIGHT/...
/ISSUED AT 327 PM EDT FRI MAR 27 2015/
BASE OF SHORT WAVE WILL BE ROTATING ACROSS NORTHERN PORTIONS OF
FORECAST AREA THROUGH THIS EVENING. ONLY WEAK ECHO RETURNS NOTED
TO THE WEST... AND NAM/ECMWF/SREF IN AGREEMENT AND NOT AS BULLISH
AS GFS BRINGING LIGHT RAIN ACROSS. DEEP NORTHWEST FLOW WILL
PROVIDE DRY CONDITIONS ACROSS AREA TOMORROW AND SUNDAY...WITH GOOD
COLD AIR ADVECTION. MAIN FORECAST CONCERN IS FREEZING TEMPERATURES
TOMORROW MORNING AND AGAIN SUNDAY MORNING. HAVE EXPANDED FREEZE
WARNING TO INCLUDE MUCH OF NORTH AND CENTRAL GEORGIA INCLUDING
ATLANTA AND ATHENS. THE FREEZE WATCH FOR SUNDAY NOW ENCOMPASSES
AREA JUST NORTH OF COLUMBUS AND MACON. HAVE GONE AHEAD AND
INCLUDED NORTHEAST GA IN WATCH AND WARNING DUE TO HOW COLD THE
TEMPERATURES ARE EXPECTED TO GET. TECHNICALLY THE FREEZE PROGRAM
WILL NOT START UNTIL APRIL 15TH...BUT WANTED TO MAKE SURE ANY
TENDER VEGETATION OR PETS WERE ACCOUNTED FOR.


ATWELL


.LONG TERM /SUNDAY THROUGH FRIDAY/...
/ISSUED AT 327 PM EDT FRI MAR 27 2015/
INCREASED THE POPS ON SUNDAY NIGHT THROUGH TUESDAY WITH THE NEXT
SYSTEM AS BOTH MODELS ARE COMING INTO BETTER AGREEMENT. MODELS
