Area forecast discussion, Jul 22, 4:15 PM EDT, 2 hours 35 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON WV
415 PM EDT TUE JUL 22 2008

.SYNOPSIS...
UPPER LEVEL DISTURBANCES WILL CAUSE A CHANCE OF THUNDERSTORMS
THIS AFTERNOON AND TONIGHT. A COLD FRONT APPROACHES TONIGHT...EXITS
WEDNESDAY. HIGH PRESSURE BUILDS IN FOR THURSDAY.

&&

.NEAR TERM /THROUGH WEDNESDAY/...
18Z SFC ANALYSIS SHOWS FRONT IN PRETTY MUCH THE SAME PLACE IT HAS
BEEN OVER THE PAST 12 HOURS...NW OHIO THROUGH CENTRAL IN. LEFTOVER
DEBRIS CLOUDS FROM MORNING MCS HAS THINNED OUT NICELY PER LATEST
VIS SAT. MODELS ALL OVER THE PLACE WITH PLACEMENT OF ORGANIZED
CONVECTION...WITH GFS FOCUSING MORE ALONG THE FRONT IN CENTRAL OH.
LOCAL MODELS ALSO KEEP MOST OF CONVECTION NW OF CWA THIS
AFTERNOON. STILL EXPECT SOME CONVECTION TO FIRE OVER THE AREA THIS
AFTERNOON WITH INCREASING INSTABILITY AND LOW LEVEL CONV WITH ANY
BOUNDARIES FROM EARLIER MCS.

NAM...RUC...AND GFS BRING AN AREA OF CONVECTION THIS AFTERNOON
EASTWARD THROUGH KY...INITIATED FROM OUTFLOW BOUNDARY FROM EARLIER
MCS OVER WESTERN KY. LATEST VIS SHOWING THIS QUITE WELL...WITH
STORMS FIRING OVER SOUTH CENTRAL KY. EXPECT THIS ACTIVITY AND
ASSOCIATED MCV TO CONTINUE TO DEVELOP THROUGH THE AFTERNOON. A
MOVEMENT MORE TOWARD THE NE IS EXPECTED AS THIS AREA MOVES INTO
CWA TOWARD 00Z...AS H5 TROUGH SHARPENS. MAIN THREAT WITH
CONVECTION WOULD BE DAMAGING WIND. AS TROUGH SHARPENS...SFC FRONT
WILL BEGIN TO SAG SE...TAKING MOST OF WED TO CLEAR CWA. THIS
SPELLS ANOTHER ROUND OF CONVECTION TOMORROW AFTN WITH
FROPA...MAINLY EASTERN PORTIONS OF CWA.

CODED UP LIKELY POPS WITH MCV THIS EVENING AND EARLY TONIGHT AND
AGAIN WITH WITH FROPA ON WED. CHC POPS IN BETWEEN. FOR TEMPS
FOLLOWED CLOSE TO MET...WHICH SEEMS TO BE A GOOD COMPROMISE WITH
OTHER GUIDANCE.

&&

.SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/...
MODELS HAVE MEAN UPPER TROUGH OVER SOUTHEAST CANADA AND THE
NORTHEASTERN U.S. THIS PERIOD. BY WEDNESDAY NIGHT...MOST OF THE
EFFECTS OF THE ABOVE MENTIONED SHORT WAVE AND COOL FRONT WILL HAVE
EXITED EAST OF OUR AREA. HIGH PRESSURE WITH MUCH DRIER AND LESS HUMID
AIR WILL DOMINATE THURSDAY INTO MOST OF THE DAY FRIDAY. AIR ALOFT
NOT COOL ENOUGH AND LOW LEVEL MOISTURE NOT HIGH ENOUGH TO SUPPORT
DIURNAL POPS. TEMPS WILL BE NEAR NORMAL FOR THIS TIME OF YEAR.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
MODELS AGREE THE MEAN UPPER TROUGH OVER THE NORTHEASTERN U.S. WILL
BE MAINTAINED THIS PERIOD. WHILE A SERIES OF SHORT WAVES AND
REINFORCING SHOTS OF COOLER AIR WILL MOVE ACROSS OUR REGION THIS
PERIOD...TIMING AND EXACT TRACK OF THESE SYSTEMS THIS FAR OUT IS
DIFFICULT. HAVE CHOSEN...ALONG WITH HPC...TO FOCUS ON THE FRONTAL
BOUNDARY WHICH MEANDERS JUST SOUTH OF OUR AREA THIS PERIOD. THIS
KEEPS SOME CHANCE POPS IN THE FORECAST NEARLY EVERY DAY...ESPECIALLY
OVER THE SOUTH WHERE WAVES OF LOW PRESSURE WILL RIDE ALONG THE
FRONT. ANY SHORT WAVE/REINFORCING SHOT OF COOLER AIR TRAVERSING THE
UPPER TROUGH WILL FURTHER ENHANCE THE PROSPECTS FOR CONVECTION
ACROSS THE AREA. ONE THING IS ALMOST CERTAIN...NO HEAT WAVES OR
EXTENDED DRY PERIODS. TEMPERATURES NEAR NORMAL.
&&

.AVIATION /20Z TUESDAY THROUGH SUNDAY/...
VFR SHOULD PREVAIL THROUGH THE AFT HRS AT MOST TAF SITES. WIDELY
SCT TSRA WILL DEVELOP ACROSS THE AREA THIS AFTN...BUT LOW CHC
AND LACK OF COVERAGE PREVENT FROM MENTIONING IN TAFS.

A MCV WILL APPROACH AREA FROM KY THIS EVENING...BRINGING TSRA TO
MAINLY THE SOUTHERN AND EASTERN SITES. EXPECT MVFR IN VIS/CEILINGS
WITH THIS COMPLEX AS IT TRAVERSES ACROSS THE SOUTH AND EAST FROM
02-06Z.

SFC FRONT WILL SLOWLY CROSS THE AREA FROM THE NW THROUGH THE DAY
ON WED...CONTINUING VIS RESTRICTIONS AS CONVECTION SHOULD DEVELOP
WITH SFC HEATING.

AVIATION OUTLOOK /AFTER 18Z WEDNESDAY/... NO SIGNIFICANT WEATHER
EXPECTED.

&&

.RLX WATCHES/WARNINGS/ADVISORIES...
WV...NONE.
OH...NONE.
KY...NONE.
