AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
507 AM EST SUN DEC 6 2009
.SHORT TERM /TODAY THROUGH TUESDAY/...
HIGH PRESSURE CENTERED OVER TN/KY THIS MORNING WILL SLIDE EAST TO
THE NEAR THE MID-ATLANTIC COAST EARLY MONDAY...CONTINUING TO NOSE
INTO THE CAROLINAS AND GEORGIA THROUGH THAT TIME. FAST AND NEARLY
ZONAL UPPER LEVEL WSW FLOW ALOFT OVER MUCH OF THE EASTERN CONUS.
THIS WILL KEEP HIGH CIRRUS RACING OVERHEAD AND A QUICK PROGRESSION
OF DISTURBANCES PASSING THROUGH THE AREA. THE NEXT H2 125 KT JET
STREAK/H5 VORT MAX COUPLET PASSES THROUGH GEORGIA ON MONDAY...
WITH WARM/MOIST ADVECTION OVER TOP THE HIGH BRINGING A FEW LIGHT
SHOWERS BACK TO OUR AREA ON MONDAY. THE NEXT TROUGH PUSHING INTO
THE PACIFIC COAST CHANNELS A MERGED NORTHERN/SOUTHERN STREAM INTO
A POWERFUL 160 KT JET CROSSING THE SOUTHERN ROCKIES ON TUESDAY.
.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
THAT UPPER LEVEL SYSTEM SPAWNS LEE CYCLOGENESIS WITH A RAPIDLY
DEEPENING SURFACE LOW TRACKING FROM OKLAHOMA TO MICHIGAN BY
WEDNESDAY. AHEAD OF THIS SYSTEM...GLOBAL MODELS/ENSEMBLES DEPICT A
WARM FRONT LIFTING NORTHWARD ACROSS THE SOUTHEASTERN STATES AND
GEORGIA TUESDAY NIGHT WITH GULF MOISTURE SURGING INTO OUR AREA.
LIMITED INSTABILITY MAY BE OFFSET BY THIS STRONGLY DYNAMIC SYSTEM
TO BRING SOME SEVERE THUNDERSTORM POTENTIAL...ESPECIALLY GIVEN THE
IMPRESSIVE SHEAR TUESDAY NIGHT INTO EARLY WEDNESDAY. HEAVY RAIN IS
A BETTER CERTAINTY WITH RAINFALL AMOUNTS LOOKING TO BE AT LEAST IN
THE 1-2 INCH RANGE. THE COLD FRONT SHOULD SWEEP THROUGH GEORGIA ON
WEDNESDAY...WITH A MODIFIED CANADIAN AIRMASS ARRIVING IN ITS WAKE.
THAT COOL HIGH WILL PASS OVERHEAD THURSDAY AND FRIDAY BEFORE WE
REPEAT THE CYCLE WITH ANOTHER DISTURBANCE ARRIVING ON SATURDAY.

.AVIATION...
HIGH PRESSURE OVER THE AREA SHOULD KEEP VFR CONDITIONS THOUGH THE
TAF PERIOD. WINDS ARE OUT OF THE NW THIS MORNING BUT THEY SHOULD
TURN TO THE NE AND EVENTUALLY THE EAST AS THE HIGH PRESSURE RIDGE
MOVES EAST INTO THE MID ATLANTIC STATES THIS EVENING. NO
PRECIPITATION OR RESTRICTIONS TO VSBYS EXPECTED. THE MODELS ARE
TRYING TO SHOW SOME RETURN MOISTURE FROM THE ATLANTIC LATE TONIGHT
WHICH MAY BRING SOME MID LEVEL STRATUS IN OVER THE STATE. IF THIS
HAPPENS SHOULD NOT SEE CLOUDS BELOW 5000FT AS THE LOWER LEVELS STAY
DRY.
