AREA FORECAST DISCUSSION  
NATIONAL WEATHER SERVICE CHARLESTON WV  
552 AM EST SAT NOV 16 2024  
   
SYNOPSIS  
 
GLOOMY SKIES PERSIST INTO THE MORNING BEFORE CLEARING OUT IN  
THE AFTERNOON OR EVENING. DRY THIS WEEKEND INTO EARLY NEXT  
WEEK. NEXT SYSTEM ARRIVES DURING THE WORK WEEK.  
 
 
   
NEAR TERM /THROUGH TONIGHT/  
 
AS OF 247 AM SATURDAY...  
 
THE CENTER OF A SURFACE HIGH PRESSURE MOVES OVERHEAD TODAY, RELAXING  
THE PRESSURE GRADIENT AND PROMOTING NEAR CALM WINDS. MEANWHILE, AN  
UPPER LEVEL RIDGE ARRIVES FROM THE WEST PROVIDING VERY DRY AIR  
ALOFT. THIS LATER SYSTEM WILL PRODUCE STRONG SUBSIDENCE, WHICH HAS  
TRAPPED LAKE-ENHANCED MOISTURE FORMING A VAST AREA OF LOW STRATUS  
ACROSS THE REGION. LIGHT DRIZZLE MAY FALL FROM SUCH CLOUD DECK  
ESPECIALLY AS MOISTURE SQUEEZES AGAINST THE MOUNTAINS UNDER  
NORTHWEST FLOW. EXPECT CLEARING SLOWLY SPREADING FROM WEST TO  
EAST ACROSS THE LOWLANDS LATE THIS AFTERNOON OR EVENING AND  
PERHAPS STAYING CLOUDY ALONG THE MOUNTAINS.  
 
AFTERNOON TEMPERATURES WILL STRUGGLE TO REACH THE UPPER 50S ACROSS  
THE LOWLANDS, RANGING INTO THE MID 40S NORTHEAST MOUNTAINS. LOWS  
TONIGHT WILL GENERALLY BY IN THE 30S, EXCEPT UPPER 20S ACROSS  
THE NORTHEAST MOUNTAINS.  
 
 
   
SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/  
 
AS OF 315 AM SATURDAY...  
 
KEY POINTS:  
* QUIET AND MILD TO CLOSE THE WEEKEND.  
* MOSTLY DRY START TO THE WORK WEEK, DESPITE THE ENCROACHMENT OF A  
FRONT.  
 
AN UPPER RIDGE AND HIGH PRESSURE WILL ALREADY BE IN PLACE OVER THE  
AREA, RESULTING IN A DRY CONCLUSION TO THE WEEKEND. SUNDAY NIGHT  
INTO MONDAY, THE RIDGE WEAKENS AND HIGH PRESSURE RETREATS AS A  
SYSTEM PASSES TO THE NORTH. A FRONT ASSOCIATED WITH THIS SYSTEM  
DESCENDS SOUTH TOWARDS THE CWA DURING THE DAY; HOWEVER, IT IS  
UNCERTAIN EXACTLY HOW FAR SOUTH THE FRONT WILL GO BEFORE ITS  
PROGRESS IS HALTED, AND THEN REVERSED, IN RESPONSE TO THE APPROACH  
OF ANOTHER SYSTEM. WHILE INCREASED CLOUD COVER IS ANTICIPATED  
WITH THIS FRONT, WIDESPREAD PRECIPITATION IS NOT. MUCH OF THE  
AREA SHOULD REMAIN DRY, THOUGH SPOTTY SHOWERS AREN'T OUT OF  
THE REALM OF POSSIBILITY.  
 
TEMPERATURES HOVER ABOVE NORMAL EARLY NEXT WEEK, WITH DAYTIME  
HIGHS RANGING FROM 50S TO MID 60S AND MUCH OF THE AREA  
EXPERIENCING LOWS IN THE 40S.  
 
 
   
LONG TERM /TUESDAY THROUGH FRIDAY/  
 
AS OF 315 AM SATURDAY...  
 
KEY POINTS:  
* SYSTEM BRINGS CLOUDS AND PRECIPITATION FOR THE MAJORITY OF THE  
WORK WEEK.  
* RAIN EXPECTED THROUGH MID WEEK.  
* WINTRY PRECIPITATION POSSIBLE LATE WEEK, AT LEAST FOR THE  
MOUNTAINS.  
 
A SYSTEM IS ANTICIPATED TO TRACK NORTHEAST OUT OF THE SOUTH-CENTRAL  
US AND INTO THE GREAT LAKES REGION. PRECIPITATION CHANCES SHOULD  
INCREASE ON TUESDAY AS THE SYSTEM BUOYS A WARM FRONT NORTH OF THE  
AREA AND THEN WARM, MOIST AIR FLOWS IN BEHIND THE FRONT. A COLD  
FRONT AND SUBSEQUENT REINFORCING FRONT SWEEP THROUGH MID WEEK WHILE  
THE PARENT LOW CONTINUES TO SPIRAL OVER THE GREAT LAKES. WINDS  
BECOME STRONG AND TEMPERATURES FALL AS COLD AIR ADVECTS INTO  
THE AREA DURING THE LATTER HALF OF THE WEEK. MEANWHILE, MOISTURE  
WRAPS AROUND BEHIND THE LOW AND CONTINUES TO SUPPORT  
PRECIPITATION THROUGH THE END OF THE LONG TERM FORECAST PERIOD.  
 
IN AND NEAR THE MOUNTAINS: THE PRECIPITATION TYPE SHOULD BE ALL  
RAIN UNTIL THE INJECTION OF COLDER AIR OCCURS MID WEEK. THIS  
SHOULD FACILITATE THE INTRODUCTION OF WINTRY PRECIPITATION BY  
THURSDAY. TEMPERATURES ARE THEN LIKELY TO REMAIN COLD ENOUGH TO  
SUPPORT SNOW OR A RAIN/SNOW MIX THROUGH THE END OF THE WEEK.  
 
LOWLANDS: RAIN PERSISTS AS THE DOMINANT PRECIPITATION TYPE NEXT  
WEEK, THOUGH A FEW SNOWFLAKES MIGHT MAKE A BRIEF APPEARANCE IN  
PORTIONS OF THE LOWLANDS EARLY THURSDAY OR FRIDAY MORNING.  
 
 
   
AVIATION /10Z SATURDAY THROUGH WEDNESDAY/

TERMINALS WILL EXPERIENCE VFR CONDITIONS UNDER 5,000 FEET CLOUD  
DECK, WHILE EKN, AND BKW MAY SEE PERIODS OF IFR CEILINGS BEFORE  
LIFTING TO VFR LATER THIS AFTERNOON OR EVENING. BRIEF PERIODS  
OF DRIZZLE WILL BE POSSIBLE ALONG THE HIGHER TERRAIN THROUGH  
15Z.
