AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON WV
ISSUED BY NATIONAL WEATHER SERVICE PITTSBURGH PA
903 AM EDT SUN JUL 1 2012
.SYNOPSIS...
WEAK MID LEVEL DISTURBANCES WILL TRIGGER SCATTERED THUNDERSTORMS
FOR THE NEXT SEVERAL DAYS. MEANWHILE HEAT AND HUMIDITY WILL
PERSIST THROUGH NEXT WEEK FROM THE RIDGE OF HIGH PRESSURE.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
CONVECTION UPSTREAM IS STARTING TO ENTER THE FAR WESTERN PORTIONS
OF THE FORECAST AREA THIS MORNING. THE MODELS IN GENERAL ARE
HAVING SIGNIFICANT DIFFICULTY RESOLVING THE SHORT WAVE ASSOCIATED
WITH IT...HOWEVER THE PREFERRED DEVELOPMENT SEEMS TO BE ALONG A
QUASI-STATIONARY BOUNDARY THAT EXTENDS FROM ROUGHLY CINCINNATI TO
CHARLESTON AT THE MOMENT. THE FORECAST HAS UPDATED TO INCREASE
POPS AND SKY COVER ALONG AND SOUTH OF THAT GENERAL AXIS THROUGH
THE REMAINDER OF THE MORNING INTO THE EARLY AFTERNOON HOURS. THE
REST OF THE FORECAST STILL LOOKS TO BE LARGELY ON TRACK. FRIES
PREVIOUS DISCUSSION ON HEAT AND AFTERNOON DEVELOPMENT FOLLOWS...
THE REGION WILL BE IN THE SAME PATTERN AS LAST FEW DAYS AGAIN FOR
THE AFTERNOON AND TONIGHT ON THE NORTH SIDE OF THE RIDGE...WITH
YET AGAIN ANOTHER HOT AND HUMID DAY. STRONG INSTABILITY DEVELOPING
ONCE AGAIN ALONG WITH MODERATE SHEAR AND SUFFICIENT LOW-LEVEL
MOISTURE WILL BRING THE POSSIBILITY OF AFTERNOON STORMS, WITH THE
BETTER CHANCE FOR SEVERE WEST OF THE OHIO RIVER. WITH GFS/NAM
INDICATING 850 TEMPS WARMING TO 20-22C, HIGHS WILL RANGE FROM THE
UPPER 90S ACROSS THE KY/OH/WV TRI-STATE AREA TO THE LOWER 90S
ACROSS NORTH-CENTRAL WV. ANOTHER HEAT ADVISORY IS IN EFFECT FOR
SUNDAY AFTERNOON...MAINLY FOR THE CRW- HTS VCNTY ON WEST AS HEAT
INDICES WARM INTO THE 100-105 RANGE.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH MONDAY NIGHT/...
WITH NORTHWEST FLOW CONTINUING ACROSS THE REGION...EXPECT TRAIN OF
CONVECTIVE COMPLEXES/UPPER LEVEL IMPULSES TO CONTINUE. TIMING AND
LOCATION OF EACH INDIVIDUAL COMPLEX IS VERY TOUGH. BLENDED TOWARDS
THE NAMDNG5...WHICH AT LEAST SHOWS SOME PROGRESSION OF INDIVIDUAL
SYSTEMS ACROSS THE FORECAST AREA...BUT AGAIN...CONFIDENCE IS FAIRLY
LOW IN SPECIFICS AT THIS POINT...AND FURTHER REFINEMENT WILL LIKELY
BE NEEDED AS WE HEAD INTO NEXT WEEK. WITH THE CENTRAL US RIDGE
STAYING IN PLACE...EXPECT TO SEE THE ABOVE NORMAL TEMPERATURES
CONTINUE THROUGH THE SHORT TERM...ALTHOUGH IT DOES NOT LOOK TO BE AS
HOT AS PREVIOUS FEW DAYS.
&&
.LONG TERM /TUESDAY THROUGH SATURDAY/...
UPPER RIDGE TO HOLD ON PLACE OVER CENTRAL CONUS WITH CWA STILL
POSSIBLE TO HANG ONTO 500MB FLOW...AND THUS DISTURBANCES ALOFT.
THEREFORE...PATTERN WILL LINGER FOR THE FORESEEABLE FUTURE WITH
HOT WEATHER IN PLACE...BUT CHANCES FOR SHOWERS AND STORMS.
CARRYING THE BETTER CHANCES DURING THE DAYS BUT NOT ELIMINATING
THEM AT NIGHT. NO RELIEF IN SIGHT WITH THE TEMPERATURES HOLDING IN
THE 90S FOR THE LOWLANDS AND 80S IN THE MOUNTAINS.
&&
.AVIATION /13Z SUNDAY THROUGH THURSDAY/...
SHOWERS AND ISOLATED THUNDERSTORMS DEVELOPED THIS MRNG OVER PARTS OF
SOUTHERN OHIO...TO THE NORTH OF STALLED SFC BOUNDARY...AND IN
ASSOCIATION WITH WEAK SHORTWAVE IN THE WNW FLOW ALOFT. MENTION OF
MORNING PCPN WL THUS BE INCLUDED IN HTS AND CRW TAFS IN THE FORM OF
TEMPO GROUPS.
OTHERWISE...AREAS OF MVFR...AND ISOLATED IFR IF FOG WILL QUICKLY
IMPROVE TO VFR AS THE MORNING PROGRESSES. SCATTERED THUNDERSTORMS
MAY IMPOSE MORE RESTRICTIONS THIS AFTERNOON AND THIS EVENING.
FORECAST CONFIDENCE THROUGH 00Z MONDAY...MEDIUM.
