Area forecast discussion, Jun 27, 9:35 PM EDT, 2 hours 14 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON WV
935 PM EDT MON JUN 27 2011

.SYNOPSIS...
COLD FRONT APPROACHES TONIGHT...THEN PASSES ON TUESDAY. HIGH
PRESSURE WEDNESDAY INTO FRIDAY WITH A WARMING TREND.

&&

.NEAR TERM /THROUGH TUESDAY/...
LOCAL HIGH RESOLUTION MODELS CONTINUE TO STRUGGLE. CONVECTION WAS
SLOWER TO GET GOING THAN INITIALLY SUGGESTED BY MODELS...BECAUSE OF
BROAD ZONE OF CONVECTIVE INHIBITION ACROSS THE CENTRAL TO NORTHERN
PART OF THE AREA. MEANWHILE...FAR SOUTHERN ZONES GOT A BRIEF LINE OF
STRONG CONVECTION EARLIER THIS EVENING AS ADVERTISED...WHERE THERE
WAS NO CONVECTIVE INHIBITION AND CAPES RANGED TO AROUND 2000 J/KG.
HOWEVER...CONVECTION NOW HAS QUICKLY FIRED TO THE WEST WITH INCOMING
SHORTWAVE...WELL AHEAD OF SURFACE FRONT...ALONG AXIS OF DEEP
MOISTURE CONVERGENCE. POPS HAVE BEEN ADJUSTED FOR THIS EARLIER
TIMING BY SEVERAL HOURS.

THESE STORMS HAVE WEAK ROTATION...YET ARE ELEVATED/HIGH BASED WITH
SURFACE-BASED CONVECTIVE INHIBITION. CEILING HEIGHTS WITH THESE
STORMS HAVE BEEN THE THOUSANDS OF FEET OFF THE GROUND...NOT
HUNDREDS. THE FORCING AND MOISTURE CONVERGENCE IS ALOFT.
HOWEVER...THE STORMS WILL BE MONITORED CLOSELY ON RADAR IN
CASE STRONGER CIRCULATIONS CAN REACH CLOSER TO THE GROUND.

DEEPER MOISTURE BEGINS TO ADVECT EAST DURING THE DAY TUESDAY...BUT
ACTUAL SURFACE FRONT WILL LAG BEHIND BY SEVERAL HOURS. EXPECTING
LINE OF SCATTERED DIURNALLY DRIVEN THUNDERSTORMS TO DEVELOP ALONG
THE FRONT...INCREASING IN COVERAGE AS THE FRONT ADVECTS EAST INTO
THE MOUNTAINS EARLY TO MID AFTERNOON.

&&

.SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY NIGHT/...
COLD FRONT MOVES OUT OF THE CWA TUESDAY NIGHT...WITH LINGERING
SHOWERS AND STORMS OVER THE EASTERN HALF OF THE CWA.  HIGH PRESSURE
THEN BUILDS IN AND WE ARE REWARDED WITH CLEAR SKIES AND DRY
WEATHER.  USED A COMBO OF GUIDANCE FOR TEMPS...AND PATTERN SHOWS A
SLOW WARMING TREND INTO THE MID 80S BY THE MIDDLE OF NEXT WEEK.

&&

.LONG TERM /FRIDAY THROUGH MONDAY/...
USED A BLEND OF THE GFS AND ECMWF FOR THE LONG TERM.  A WARM FRONT
APPROACHES FROM THE WEST ON FRIDAY...IT MAY PRODUCE A FEW SHOWERS IN
THE NORTHWESTERN PART OF THE CWA.  THEN A COLD FRONT SWINGS THROUGH
DURING THE DAY ON SATURDAY. SHOWERS AND THUNDERSTORMS MAY DEVELOP
OUT IN FRONT OF THE COLD FRONT...WITH A CHANCE OF RAIN HANGING
AROUND THROUGH SUNDAY.  THE MODELS SHOW EXTREMELY DIFFERENT
SOLUTIONS FOR MONDAY AND TUESDAY.  DECIDED TO SIDE WITH THE RAINER
ECMWF SOLUTION.  HIGH PRESSURE MOVES IN BEHIND THE COLD FRONT...AND
LOBES OF VORTICITY ROTATE AROUND THE HIGH PRESSURE.
THEREFORE...HAVE A CHANCE OF SHOWERS AND TSTORMS IN THE FORECAST FOR
MONDAY AND TUESDAY.

FOR TEMPS...WENT WITH HPCS MAX AND MINS WITH SLIGHT ADJUSTMENTS.  A
WARMING TREND IS ON TAP...WITH THE POTENTIAL OF MAX TEMPS OVER 90
FOR FRIDAY AND INTO NEXT WEEKEND.

&&

.AVIATION /02Z TUESDAY THROUGH SATURDAY/...
BATCH OF AT LEAST SCATTERED SHOWERS AND THUNDERSTORMS WILL CONTINUE
TO CROSS THE AREA THROUGH THE NIGHT WITH UPPER DISTURBANCE...AHEAD
OF INCOMING FRONT. FINAL SURFACE FRONT TUESDAY COULD HAVE ADDITIONAL
SHOWERS/THUNDERSTORMS. GENERALLY LOOKING AT MVFR CIGS AND/OR VIS
WITH SHOWERS AND VALLEY FOG OVERNIGHT. ALSO...POST FRONTAL MVFR CIGS
LASTING THROUGH MUCH OF TUESDAY MORNING. IFR NOT OUT OF THE QUESTION
IN THE MOUNTAINS...AND FOR AREAS THAT GET A GOOD AMOUNT OF RAIN
FROM INDIVIDUAL STORM CELLS.

FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 00Z WEDNESDAY...

FORECAST CONFIDENCE: MEDIUM.

ALTERNATE SCENARIOS: TIMING OF CIGS AND VSBYS WITH TSTMS COULD VARY
WITH THE COLD FRONT OVERNIGHT INTO TUESDAY.
