/ISSUED 635 AM EST THU FEB 27 2020/  
 
SHORT TERM /TODAY THROUGH FRIDAY/...  
 
A STRONG SHORT WAVE WAS MOVING EAST OF THE GREAT LAKES/OH VALLEY  
THIS MORNING. WRAP AROUND FROM THIS SYSTEM WAS GIVING MUCH OF NORTH  
AND WEST GA CLOUDS...WITH ISOLATED SNOW FLURRIES IN THE FAR NORTH.  
EXPECT THE FLURRIES TO DISSIPATE BY AROUND SUNRISE. CLOUDS SHOULD  
SCATTER LATER THIS MORNING. COLD AIR ADVECTION WITH GUSTY NORTHWEST  
WINDS WILL KEEP TEMPERATURES TODAY IN THE 40S AND 50S. WINDS  
WILL DIMINISH BY AFTERNOON. ANOTHER FAST MOVING SHORT WAVE WILL MOVE  
ACROSS THE OH/TN VALLEY AREA ON FRIDAY. POPS RETURN TO NORTH GA BY  
SUNRISE FRIDAY...AND THIS WILL GIVE US ANOTHER CHANCE FOR A WINTRY  
MIX OF PRECIPITATION FROM SUNRISE FRIDAY THROUGH THE LATE MORNING.  
QPF AMOUNTS ARE LOW WITH THIS SHORT WAVE AND ANY SNOW ACCUMULATIONS  
SHOULD BE MINIMAL. EXPECT LESS THAN AN INCH AT HIGHER ELEVATIONS.  
FRIDAY MORNING.

LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...  
 
THE LONG TERM PERIOD STARTS ON FRIDAY EVENING WITH A LONG WAVE  
TROUGH TRAVERSING ACROSS THE EAST COAST. NORTHWESTERLY FLOW ALOFT  
WITH MINOR SHORTWAVE PERTURBATIONS AT THE BASE OF THE TROUGH WILL  
BRING A CHANCE OF WINTRY PRECIPITATION TO THE NORTHERN PARTS OF THE  
CWA, ENDING ON SATURDAY MORNING. WITH LIGHTER QPF GUIDANCE AMOUNTS,  
SNOW ACCUMULATIONS SHOULD BE LIMITED TO THE NORTH GEORGIA MOUNTAINS  
AND SHOULD REMAIN LESS THAN AN INCH, WITH LOCALLY HIGHER AMOUNTS AT  
THE HIGHER ELEVATIONS. THERE IS ALSO THE POTENTIAL FOR PATCHY BLACK  
ICE ACROSS PORTIONS OF FAR NORTHERN GEORGIA WHERE ANY RAIN/SNOW THAT  
DOES FALL MAY FREEZE OVERNIGHT.  
 
MOVING INTO THE LATTER PARTS OF THE WEEKEND, HIGH PRESSURE MOVES  
INTO THE SOUTHEAST WITH SLIGHT RIDGING ALOFT BRINGING IN A PERIOD OF  
DRY WEATHER THROUGH SUNDAY. BY MONDAY, THIS SURFACE HIGH SHOULD MOVE  
OUT OF THE CWA WITH AN INCREASE IN POPS DUE TO SHORTWAVE WAVE  
PERTURBATIONS IN A BRIEF RIDGE.  
 
MID LEVEL SOUTHWESTERLY FLOW RETURNS TO THE CWA ON TUESDAY AHEAD OF  
A DEEP TROUGH OVER THE GREAT PLAINS. MODELS ARE CURRENTLY SHOWING  
DISCREPANCIES FOR THIS SYSTEM AS THE GFS IS HINTING AT THE  
DEVELOPMENT AND THE CONTINUATION OF A MID-LEVEL CUT-OFF/NEAR CUT-OFF  
LOW WHILE THE ECMWF HAS THE LOW DEVELOPING, BUT IS THEN ABSORBED  
INTO THE TROUGH. AS THE SYSTEM PROGRESSES EASTWARD,A SURFACE LOW  
COULD DEVELOP NEAR THE OHIO RIVER VALLEY ON WEDNESDAY, BRINGING IN  
SOUTHWESTERLY FLOW AND INCREASED POPS TO THE CWA AHEAD OF THE  
APPROACHING COLD FRONT. THUNDER WAS ADDED TO GRIDS FOR THIS SYSTEM  
DUE TO CAPE VALUES APPROXIMATELY 300 J/KG ACROSS CENTRAL GEORGIA.  
THE COLD FRONT SHOULD MOVE OUT OF THE AREA ON THURSDAY TO END THE  
EXTENDED FORECAST PERIOD.
