AREA FORECAST DISCUSSION

SYNOPSIS
 
 
HIGH PRESSURE ALONG WITH COOLER AND DRIER AIR TO OVERTAKE THE  
REGION TODAY AND SUNDAY. EARLY NEXT WEEK THE NEXT FRONTAL  
SYSTEM WILL APPROACH THE REGION ALONG WITH CHANCES OF SHOWERS  
AND THUNDERSTORMS.  
 

 
   
NEAR TERM /THROUGH TONIGHT/
 
 
EARLY THIS MORNING: MOSTLY DRY CONDITIONS EXPECTED THROUGH  
SUNRISE. LINGERING CLOUD COVER EXPECTED ACROSS THE SOUTHERN  
MIDLANDS AND THE CSRA. MORNING LOWS WILL RANGE FROM THE MID 60S  
IN THE NORTHERN MIDLANDS TO AROUND 70 IN THE CSRA.  
 
TODAY AND TONIGHT: MAIN COLD FRONT WILL BE SOUTH OF THE CWA  
THROUGH THE PERIOD. THERE WILL STILL BE SOME LINGERING LOW-LEVEL  
MOISTURE TO START OFF THE DAY OVER THE SOUTHERN HALF OF THE CWA  
DUE TO A WEAK ONSHORE FLOW. THESE WILL MIX OUT BY LATE MORNING,  
ALLOWING FOR A GOOD AMOUNT OF SUNSHINE. TEMPERATURES RISE INTO  
THE MID TO UPPER 80S, BUT WITH A DRIER AIRMASS ACROSS MUCH OF  
THE AREA, IT SHOULD FEEL MORE PLEASANT. SKIES SHOULD BE CLEARER  
TONIGHT. WITH A WEAKER LOW-LEVEL JET OVERNIGHT, THE LIGHTER  
WINDS AND DRIER AIR SHOULD ALLOW OVERNIGHT LOWS TO FALL DOWN  
INTO THE MIDDLE 60S FOR MOST AREAS.  
 

 
   
SHORT TERM /SUNDAY THROUGH MONDAY/
 
 
AN UNSEASONABLY DEEP UPPER LEVEL TROUGH OVER NEW ENGLAND WILL PUSH A  
COLD FRONT SOUTH OF THE CSRA AND MIDLANDS ON SUNDAY. NORTHWEST FLOW  
ALOFT WILL BRING MUCH DRIER AIR INTO THE REGION WITH DEW POINTS  
LOWERING INTO THE MID 50S TO LOWER 60S. A DOWNSLOPE FLOW  
COMPRESSION WILL OFFSET SOME OF THE H5 HEIGHT FALLS WITH HIGHS  
IN THE MID TO UPPER 80S. THE LOWER DEW POINTS WILL ALLOW LOW  
TEMPS TO DROP INTO THE MID TO UPPER 60S. A FEW SHELTERED  
LOCATIONS MIGHT DROP INTO THE LOWER 60S. LOW LEVEL MOISTURE  
GRADUALLY RETURNS TO THE REGION ON MONDAY AHEAD OF AN  
APPROACHING COLD FRONT WHICH SHOULD RESULT IN A CHANCE OF  
DIURNAL SHOWERS AND THUNDERSTORMS.  
 

 
   
LONG TERM /MONDAY NIGHT THROUGH FRIDAY/
 
 
A WEAK AND BROAD UPPER LEVEL TROUGH LINGERS OVER THE NORTHEAST  
U.S. NEXT WEEK. A FRONTAL BOUNDARY STALLED IN THE VICINITY OF  
THE CSRA AND MIDLANDS SHOULD BE THE PRIMARY FORCING MECHANISM  
FOR DIURNAL SCATTERED SHOWERS AND THUNDERSTORMS EACH DAY. BELOW  
NORMAL H5 HEIGHTS SHOULD LEAD TO BELOW NORMAL TEMPERATURES FOR  
MID AUGUST.  
 

 
   
AVIATION /06Z SATURDAY THROUGH WEDNESDAY/
 
 
BROKEN MVFR/IFR CEILINGS ARE EXPECTED TO CONTINUE THROUGH EARLY  
MORNING OVER THE CSRA TAF LOCATIONS OF AGS/DNL WHERE DEEPER  
MOISTURE STILL RESIDES. THERE WILL ALSO BE PERIODS OF THOSE  
SAME CONDITIONS AT CAE/CUB/OGB AT LEAST THROUGH 09Z. DRIER AIR  
AFTER SUNRISE SHOULD BEGIN TO IMPROVE CONDITIONS IN THE  
MIDLANDS BY 13Z, WITH THE CSRA SITES IMPROVEMENT DELAYED UNTIL  
MID-MORNING. ALL SITES VFR BY 16Z WITH PLEASANT WEATHER EXPECTED  
THE REMAINDER OF THE TAF PERIOD.  
 
EXTENDED AVIATION OUTLOOK...AFTERNOON SHOWERS AND THUNDERSTORMS  
BECOME POSSIBLE AGAIN STARTING ON MONDAY.
