/ISSUED 354 AM EDT SAT OCT 21 2017/  
 
SHORT TERM /TODAY THROUGH SUNDAY/...  
 
THE SHORT TERM STARTS OFF HIGH AND DRY BUT WE FINALLY SEE SOME  
PRECIP MOVING INTO THE AREA AHEAD OF APPROACHING FRONTAL SYSTEM.  
MAIN HIGH PRESSURE RIDGE IS WEAKENING AND LOOSING ITS GRIP ON THE  
SOUTHEASTERN U.S. WE WILL SEE INCREASED CLOUD COVER OVER THE NEXT 24  
HOURS WITH SOME SHOWERS AND ISOLATED THUNDERSTORM PUSHING INTO  
THE AREA BEGINNING SUNDAY AFTERNOON/EVENING. THE INCREASED CLOUD  
COVER IS ACTUALLY COMING IN DUE TO THE MOIST EASTERLY FLOW AHEAD  
OF THE NEXT FRONTAL SYSTEM...WHICH IN NOW DEVELOPING OVER THE  
CENTRAL AND SOUTHERN PLAINS. THIS FRONTAL BOUNDARY WILL CONTINUE  
TO DEVELOP...BECOMING MORE ORGANIZED AS IT PUSHES INTO THE MS  
RIVER VALLEY SUNDAY MORNING. THE DEEPER MOISTURE ASSOCIATED WITH  
THE FRONT DOESN'T MOVE INTO WEST GA UNTIL AFTER 00Z MON. HIGH  
TEMPS SAT AND SUN STAY MAINLY IN THE 70S AND LOWER 80S WITH LOW  
TEMPS TONIGHT IN THE 50S.  
 
01  
 
LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...  
 
STILL SOME VARIATION CONCERNING TIMING/PATH/STRENGTH OF THE SYSTEM  
SWEEPING THROUGH THE REGION AT THE BEGINNING OF THE PERIOD. HOWEVER,  
EARLY MONDAY THROUGH MONDAY EVENING IS STILL LOOKING LIKE THE MOST  
LIKELY TIMEFRAME ACROSS THE FORECAST AREA. MODELS CONTINUE TO SHOW  
MINIMAL INSTABILITY, BUT STRONG DYNAMICS AND GOOD SHEAR CONTINUE TO  
POINT TO AT LEAST A SLIGHT CHANCE FOR SOME STRONG TO SEVERE  
CONVECTION DURING THE DAY MONDAY. SYSTEM MOVES EAST QUICKLY OVERNIGHT  
INTO TUESDAY MORNING, BUT SECONDARY STRONG SHORT WAVE AND MARGINAL  
RESIDUAL MOISTURE KEEPS A SLIGHT CHANCE FOR A FEW SHOWERS ACROSS THE  
FAR NORTH THROUGH THE DAY WEDNESDAY. GOOD SHOT OF COLD AIR BEHIND  
THIS SYSTEM BRINGS WELL BELOW NORMAL TEMPERATURES INTO THE STATE  
TUESDAY/WEDNESDAY, BUT MODELS ARE NOW SHOWING A PRETTY QUICK RECOVERY  
BY THE END OF THE WORK WEEK. ANOTHER QUICK MOVING SYSTEM SWEEPS IN  
FOR THE WEEKEND. MOISTURE RETURN IS NOT PROGGED TO BE SPECTACULAR,  
BUT SHOULD BE SUFFICIENT FOR AT LEAST A LOW CHANCE OF SHOWERS MOVING  
INTO THE NORTHWEST BY FRIDAY NIGHT, SPREADING ACROSS THE FORECAST  
AREA SATURDAY.
