AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
336 PM EDT FRI JUL 2 2010

.SHORT TERM /TONIGHT THROUGH SUNDAY NIGHT/...
CURRENT RADAR LOOP SHOWS SOME ISOLATED SHOWERS SLOWLY DISSIPATING AS
THEY MOVE WESTWARD IN THE EASTERLY FLOW. THERE IS A LARGE HIGH
PRESSURE RIDGE CENTERED OVER THE EASTERN GREAT LAKES STATES WITH A
LARGE MOISTURE PLUME EXTENDING FROM CENTRAL TX...ACROSS THE GULF OF
MEXICO...ACROSS CENTRAL FL AND OUT INTO THE ATLANTIC. THIS RIDGE IS
EXPECTED TO ROTATE SOUTHEASTWARD AND BECOME CENTERED OVER THE
CAROLINAS BY 12Z SAT. THIS SHOULD KEEP THE DEEP TROPICAL GULF
MOISTURE SOUTH OF OUR AREA THROUGH THE WEEKEND. WITH THIS RIDGE
BUILDING INTO THE SOUTHEASTERN STATES...THE AIR MASS BECOMES
REMARKABLY DRY AND STABLE THROUGH INDEPENDENCE DAY. LIS NEARING +10
SAT AND PWS DROPPING TO LESS THAN 1.0 INCH. WITH ALL THIS
SAID...HAVE DECIDED TO TAKE POPS COMPLETELY OUT OF THE FORECAST
THROUGH THE WEEKEND. AS FOR TEMPS...MAV/MET NUMBERS VERY CLOSE
SHOWING HIGHS RUNNING 3-5 DEG BELOW SEASONAL NORMS THROUGH SUN.
850MB TEMPS IN THE +12C TO +14C RANGE SHOULD SUPPORT THIS.

.LONG TERM /MONDAY THROUGH FRIDAY/...
MAIN PROBLEM IN THE LONG TERM IS WHEN WILL THE RIDGE BREAK DOWN AND
ALLOW DEEPER GULF MOISTURE TO MOVE IN. THE UPPER LEVEL RIDGE SHOULD
CONTINUE AT LEAST THROUGH MON/TUE WITH THE SURFACE RIDGE MOVING OFF
SHORE TUE. IF THIS OCCURS THE DEEPER MOISTURE SHOULD BEGIN MOVING
BACK INTO MS/AL/GA BY TUE/WED. WILL CONTINUE WITH KEEPING THE AREA
DRY THROUGH TUE...BRINGING IN SLIGHT CHANCE/CHANCE POPS WED-FRI.
TEMPS AND HUMIDITY QUICKLY RETURN TO NEAR NORMAL LEVELS BY TUE-WED.
PWS INCREASE TO ABOVE 1.5 INCHES WITH SFC WINDS VEERING FROM NE TO
SE. BACK TO HIGHS IN THE LOW TO MID 90S AND LOWS IN THE 70S.
