AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON WV
246 PM EDT SUN JUL 13 2014

.SYNOPSIS...
COLD FRONT MOVES IN THIS EVENING/TONIGHT...AND MOVES THROUGH
MONDAY MORNING. THIS BRINGS STRONG...HEAVY THUNDERSTORMS. A
STRONGER COLD FRONT MOVES THROUGH EARLY TUESDAY MORNING. QUITE
COOL MID WEEK.

&&

.NEAR TERM /THROUGH MONDAY/...
CONVECTIVE WATCH IN PLACE OVER THE BULK OF SOUTHEAST OHIO WITH A
FEW COUNTIES IN NORTH CENTRAL WEST VIRGINIA. CONVECTION HAS FIRED
ALONG A LINE OF CONVERGENCE FROM NORTHWEST PENNSYLVANIA THROUGH
SOUTHWEST OHIO AND SOUTHERN INDIANA. THIS IS JUST AHEAD OF THE
COLD FRONT THAT WILL BE MOVING SOUTH AND LOSING SPEED INTO THIS
EVENING AND TONIGHT.

THE BETTER DYNAMICS ARE CLEARLY TO THE NORTH OF THE AREA...WITH A
30-40KT LOW LEVEL JET AND A BULK SHEAR 0-6KM MAX THROUGH THE
WATCH AREA AT 40KTS. STILL HAVE PLENTY OF LOW LEVEL INSTABILITY
WITH INCREASING LAPSE RATES THANKS TO DEWPOINT INCREASES AND
HEATING RESPECTIVELY.

ROUNDS OF CONVECTION WILL AFFECT THE BULK OF THE LOWLANDS AND INTO
THE NORTHEAST MOUNTAINS THROUGH TONIGHT. WITH PWAT VALUES AROUND 2
INCHES...MAYBE A TOUCH HIGH ON THE BIASED NAM...BUT HIGH
NONETHELESS...PRECIPITATION AMOUNTS WILL NOT BE ABLE TO BE
IGNORED. THE CULPRIT FOR THIS TONIGHT WILL BE A SURFACE WAVE ALONG
THE FRONT. WE ARE INCLUDED FOR THE DAY 1 EXCESSIVE RAINFALL...SEE
THE NAM DEPICTING POCKETS OF THETA E CONVERGENCE IN THE LOW LEVELS
THROUGH TONIGHT. TRAINING PRECIPITATION OR MULTIPLE ROUNDS OF
STORMS WILL BE THE KEY FOR ANY ISOLATED FLOODING PROBLEMS. NO
WATCH HOWEVER BECAUSE OF THE DRY CONDITIONS OVER THE LAST 2-3
WEEKS. LOTS OF ROOM IN THE GROUND AND CREEKS AND RIVERS FOR
RAINFALL. BUT RAINFALL RATES MAY TRUMP THAT AS WELL.

&&

.SHORT TERM /MONDAY NIGHT THROUGH THURSDAY NIGHT/...
AMPLIFYING UPPER TROUGH OVER THE EASTERN HALF OF THE U.S. WILL DRIVE
A STRONG COLD FRONT ACROSS THE AREA MONDAY NIGHT AND TUESDAY
MORNING...WITH THE FRONT EXITING THE MOUNTAINS BY AFTERNOON. THE
MODELS HAVE COME INTO GOOD AGREEMENT WITH THE TIMING OF THE
FRONT...AND ENDING THE WIDESPREAD CONVECTION QUICKLY BEHIND THE
FRONT. WE LOOK FOR WIDESPREAD SHOWERS AND THUNDERSTORMS PRECEDING
THE FRONT...ENDING FROM WEST TO EAST DURING TUESDAY. EXPECT ONLY
LINGERING SHOWERS IN THE MOUNTAINS BY TUESDAY AFTERNOON WITH THE AID
OF UPSLOPE NORTHWEST FLOW AND COLD ADVECTION BEHIND THE FRONT.
HOWEVER...THESE WILL END LATER IN THE DAY TUESDAY AS MUCH DRIER AND
MUCH COOLER CANADIAN AIR FLOWS INTO THE REGION...COMPLIMENTS OF
STRONG CANADIAN HIGH PRESSURE RIDGING SOUTHWARD FROM CENTRAL CANADA.
THEREAFTER...CANADIAN HIGH PRESSURE WILL BRING DRY CONDITIONS WITH
WELL BELOW NORMAL TEMPERATURES TUESDAY NIGHT THROUGH THURSDAY...WITH
HIGHS IN THE 70S AND LOWS IN THE 50S.

&&

.LONG TERM /FRIDAY THROUGH SUNDAY/...
BY FRIDAY THE UPPER TROUGH LIFTS OUT AND THE FLOW BECOMES MORE
ZONAL. THERE WILL BE A WARMING TREND BACK INTO THE 80S WITH
INCREASING HUMIDITIES BY FRIDAY...AS THE SURFACE HIGH SHIFTS EAST
AND SOUTHEASTERLY FLOW BRINGS LOW LEVEL MOISTURE BACK. THUS...THERE
WILL ALSO BE A CHANCE OF A SHOWER OR STORM MAINLY IN THE MOUNTAINS
FRIDAY. FOR THE WEEKEND...ALL DEPENDS ON A WEAK UPPER TROUGH THAT
THE MODELS FORECAST TO MOVE INTO THE OHIO VALLEY...WITH NO SURFACE
REFLECTION. THERE IS ENOUGH MODEL CONSENSUS TO KEEP A CHANCE OF
CONVECTION IN THE MOUNTAINS FOR THE WEEKEND...AND A SLIGHT CHANCE IN
THE LOW LANDS. IN ANY CASE...IT WILL BE VERY WARM AND HUMID AGAIN.

&&

.AVIATION /19Z SUNDAY THROUGH FRIDAY/...
WELL...THIS IS ONE OF THOSE EXTRAORDINARILY DIFFICULT SET OF TAFS
TO DELIVER WITH THE ATTEMPTS OF BEING AS DETERMINISTIC AS POSSIBLE
WITHOUT BROAD BRUSHING THE ENTIRE FORECAST WITH TSRA WHICH HELPS
NO ONE.

CONVECTIVE WATCH CURRENTLY IN EFFECT FOR THE PKB TERMINAL. PRIMARY
THREATS ARE WIND GUSTS...ALTHOUGH HAIL CANNOT BE RULED OUT.

THERE IS A COLD FRONT APPROACHING...AND WITH DEWPOINTS AND
INSTABILITY ON THE RISE...AN EXTENSIVE THUNDERSTORM FORECAST HAS
BEEN ISSUED. WILL SEE COVERAGE OF SHOWERS AND STORMS INCREASE
THROUGH THE EVENING...WITH A SURFACE WAVE OF LOW PRESSURE RIDING
ALONG THE COLD FRONT THAT WILL BE IN THE OHIO VALLEY BY THIS
TIME. IT WILL BE HOLDING UP ITS PROGRESS...KEEPING HIGH CHANCES
FOR CONVECTION GOING THROUGH THE NIGHT. THIS IS WHERE THERE WERE
EFFORTS TO KEEP THE TSRA AT A RELATIVE MINIMUM SO AS NOT TO HAVE
12 STRAIGHT HOURS OF TSRA IN THE TAFS. UNFORTUNATELY...COULD NOT
LEAVE THE MENTION OUT...SO THE VCTS/CB WORDING WAS USED.

USED SOME EARLY ON CLUES FOR THE FIRST FEW HOURS...WITH A COUPLE
OF TEMPO GROUPS OVER THE NEXT 3 HOURS FOR PKB AND CKB WITH A LINE
ALREADY MOVING WEST TO EAST TOWARDS THESE TERMINALS. ALSO HAVE
SOME CELLULAR CONVECTION PEPPERING THE MOUNTAINS...SO NEED VCTS
FOR BKW RIGHT NOW.

COMPLICATING THE MATTER IS THAT BREAKS IN THE CONVECTION AND
TERMINALS THAT RECEIVE RAIN THAT COULD GO DOWN TO IFR FOG...EVEN
IN CLOUDS. THIS WILL BE ESPECIALLY TRUE FOR EKN AND CRW. SIMPLY
CANNOT ACCOUNT FOR THAT IN PREVAILING CONDITIONS.

IN THE END...LIKELY GOING TO NEED SOME AMD AND TEMPOS OVER THE
NEXT 12-18 HOURS.

CURRENTLY...DIURNAL MIXING IS BRINGING NON CONVECTIVE WINDS OUT
OF THE SOUTHWEST TO 25KTS. THUNDERSTORMS ASIDE...THESE SHOULD
SUBSIDE AFTER 22Z.

FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 18Z MONDAY...

FORECAST CONFIDENCE: MEDIUM ON WEATHER...LOW TO MEDIUM ON TIMING.

ALTERNATE SCENARIOS: TIMING OF TSRA WILL BE PROBLEMATIC. MAY HAVE
SOME FOG TONIGHT. AMD AND TEMPOS WILL BE NEEDED.
