SYNOPSIS
 
 
HIGH PRESSURE THROUGH MONDAY. WARMING TREND WITH DISTURBANCES  
MIDDLE OF NEXT WEEK.  
 

 
   
NEAR TERM /THROUGH MONDAY/
 
 
AS OF 1245 AM SUNDAY...  
 
A HIGH PRESSURE SYSTEM WILL BRING DRY WEATHER TO THE AREA  
THROUGH MONDAY. WITH LIGHT WINDS TONIGHT, EXPECT LOWS IN THE LOW  
TO MID 40S, WITH SOME MID TO UPPER 30S IN THE NORTHERN WEST  
VIRGINIA MOUNTAINS. CAN'T RULE OUT A FEW PATCHES OF FROST IN THE  
PROTECTED VALLEYS AWAY FROM RIVERS AND CITIES IN THE NORTHERN  
WEST VIRGINIA MOUNTAINS. WITH THE GROUND FAIRLY WARM HOWEVER,  
THINK THE POTENTIAL IS TOO LIMITED FOR AN ADVISORY.  
 

 
   
SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY/
 
 
AS OF 155 PM SUNDAY...  
 
OVERALL FORECAST THINKING REMAINS GENERALLY THE SAME. MODELS  
CONTINUE TO INDICATE A CONVECTIVE COMPLEX IN NORTHWESTERLY FLOW  
MONDAY NIGHT/TUESDAY, THAT WILL MOVE SOUTHEAST THROUGH PA. THIS  
MAY BRUSH FAR NORTHEASTERN ZONES, BUT FOR THE MOST PART, LOOKS  
TO STAY OUTSIDE OF OUR AREA WITH CLOUDS MAIN EFFECT. OTHERWISE,  
HEAT AND HUMIDITY WILL SLOWLY BE ON THE INCREASE STARTING  
TUESDAY WITH SOUTHWESTERLY FLOW INCREASING. THERE IS A SMALL  
CHANCE FOR SHOWERS AND STORMS TUESDAY NIGHT AND WEDNESDAY FROM A  
PASSING DISTURBANCE TO THE NORTHEAST, OTHERWISE, MOST AREAS  
SHOULD REMAIN RELATIVELY DRY.  
 

 
   
LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/
 
 
AS OF 155 PM SUNDAY...  
 
WARM AND HUMID CONDITIONS CONTINUE TO LINGER ACROSS THE AREA FOR  
THE LONG TERM PERIOD. RIDGE BREAKS DOWN SOMEWHAT MIDWEEK, WITH A  
FRONTAL BOUNDARY SLOWLY SAGGING SOUTH TOWARDS THE AREA. THERE IS  
THE SMALL POSSIBILITY OF A STRONG STORM MID WEEK ACROSS FAR  
NORTHERN ZONES, BUT AT THIS POINT, BETTER CHANCES LOOK TO LIE  
NORTH OF THE CWA. FRONTAL BOUNDARY WILL CONTINUE TO WAFFLE NORTH  
TO SOUTH ACROSS THE AREA OVER THE REMAINDER OF THE LONG TERM  
PERIOD, WITH HOT AND HUMID CONDITIONS, ALONG WITH SHOWERS AND  
STORMS, SOME WITH HEAVY DOWNPOURS.  
 

 
   
AVIATION /23Z SUNDAY THROUGH FRIDAY/
 
 
AS OF 705 PM SUNDAY...  
 
VFR THIS EVENING WITH SOME RIVER VALLEY FOG OVERNIGHT.  
 
DIURNAL CU FIELD IS CURRENTLY DISSIPATING WITH ONLY SOME  
PASSING CI EXPECTED THIS EVENING. OVERNIGHT, AREAS OF RIVER  
VALLEY FOG MAY DEVELOP, ESPECIALLY VICINITY OF KCRW AND KEKN.  
AMOUNT OF COVERAGE OF FOG IS A LITTLE UNCERTAIN, HOWEVER, GIVEN  
THAT THERE IS CURRENTLY QUITE A BIT OF DRY AIR IN THE LOWER  
LEVELS OF THE ATMOSPHERE. EVEN IF FOG DOES DEVELOP, A QUICK  
RETURN TO VFR AND SKC SHOULD OCCUR AREAWIDE ON MONDAY.  
 
SFC WINDS EXPECTED TO BECOME CALM NEARLY AREAWIDE TONIGHT.
