AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON WV
414 PM EDT THU JUL 19 2007
.SYNOPSIS...
A COLD FRONT MAKES ITS WAY THROUGH OVERNIGHT LATE TONIGHT...YIELDING
TO HIGH PRESSURE THIS WEEKEND. A RIDGE OF HIGH PRESSURE RETURNS
THREE H WEATHER NEXT WEEK.
&&
.NEAR TERM /THROUGH FRIDAY/...
KEEPING BUSY...SO KEEPING OUR DISCUSSIONS BRIEF THIS AFTERNOON.
FRONT MOVING SSE FROM NORTHERN INDIANA AND NORTHERN OHIO AT 20Z.
STILL PASSING DURING THE 06Z TO 12Z PERIOD...WITH LEFTOVER MOISTURE
EXITING FRIDAY.
SEVERE THREAT...DUE TO 30 TO 35 KNOT FLOW AT 5 THSD FT AGL...ALONG
WITH THE BOUYANCY GENERATED BY THE UPSTREAM HEATING...HIGHER DEW
POINTS...PLUS APPROACHING SUPPORT ALOFT.
STILL CONCERNED ABOUT TRAINING OF SHOWERS. IF REPETITIVE SHOWERS HIT
THE SAME SMALL STREAM BASIN...SOME FLASH FLOODING IS POSSIBLE
OVERNIGHT. YET...IT WOULD TAKE 2.5 TO 3 INCHES IN 3 HOURS OF RAIN IN
3 HOURS OR LESS...FOR SMALL STREAM FLASH FLOODING. 850 MB DEW
POINTS WERE 17C AT 12Z UPSTREAM. THE FLASH FLOOD WATCH IS FOR THE
ENTIRE CWA EXCEPT OUR PERRY AND MORGAN COUNTIES.
STILL GOOD INFLOW FROM CENTRAL KY AND TN INTO THE OHIO VALLEY
CONVECTION LATE THIS AFTERNOON TO HELP FEED OUR EVENING CONVECTION.
NO MAJOR CHANGES MADE TO THE DRYING ON FRIDAY. SOME FOG COULD
FORM IN THE COOLER AIR FOR LATE FRIDAY NIGHT.
&&
.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY NIGHT/...
THE CASE FOR THE PAST SEVERAL DAYS...IS STILL THE KEY...
THE UPPER AIR TROF IN THE DRIER AND FRESHER AIR FOR SATURDAY AND
SUNDAY. EVEN THOUGH THE AIR IS RELATIVELY DRY...THINKING ENOUGH
SUPPORT FROM THE UPPER AIR TROF...TO ADD SOME ISOLATED SHOWERS FOR
SATURDAY IN THE MOUNTAINOUS COUNTIES.
WILL LEAVE THE POSSIBILITY OF ANY SHOWERS ON SUNDAY FURTHER E...OUT
OF OUR CWA.
&&
.LONG TERM /MONDAY THROUGH THURSDAY/...
THE TROUBLESOME UPPER AIR TROF SHOULD BE TO OUR EAST AT START OF
EXTENDED PD. WITH WEAKENING MID AND UPPER FLOW...A WEAK SE LOW
LEVEL FLOW MAY DEVELOP. WILL ADD SOME SLIGHT CHANCE POPS FOR
DAYTIME CONVECTION IN THE UPSLOPE AREAS. DO NOT SEE ANY
SIGNIFICANT FRONTS. OTHERWISE...SAME TRENDS AS PREVIOUS
DAYS...WITH AFTERNOON TEMPERATURES HEATING UP WITH TIME.
&&
.AVIATION /20Z THURSDAY THROUGH TUESDAY/...
THUNDERSTORMS WILL CONTINUE TO DEVELOP ACROSS SOUTHEAST OH...KY AND
SOUTHERN HALF OF WV THIS AFTERNOON. THERE IS A THREAT FOR SEVERE
STORMS TO AFFECT HTS...CRW...AND BKW. HOWEVER...DUE TO THE LOW
CONFIDENCE OF WHERE A SEVERE STORM WILL MOVE...HAVE INCLUDED TEMPOS
WITH STRONG GUSTY WINDS UP TO 36 KNOTS ALONG WITH
THUNDERSTORMS...INCLUDING IFR CEILINGS AND VISIBILITIES. THE STORM
ACTIVITY SHOULD LAST THRU TONIGHT AS A COLD FRONT WILL MOVE SOUTH
TRIGGERING ADDITIONAL STRONG STORMS.
PKB...CKB...AND EKN WILL ALSO EXPERIENCE STRONG STORMS WITH GUSTY
WINDS AND IFR VISIBILITIES AND CEILINGS...BUT SEVERE THREAT IS LOWER
THERE.
THE MAIN SEVERE THREAT WILL BE DAMAGING WINDS AND SMALL HAIL.
THE WEATHER WILL IMPROVE AT MOST SITES AFTER 04Z AT PKB...HTS AND
CRW...AND AFTER 06Z AT CKB...EKN AND BKW AS THE COLD FRONT MOVES ON
THROUGH.
AVIATION OUTLOOK...IFR TO LIFR CONDITIONS ARE STILL POSSIBLE IN LOW
CLOUDS AND FOG EARLY FRIDAY AS FRONT DEPARTS....ESPECIALLY CRW...EKN
AND BKW. THE LOW CLOUDS AND DENSE FOG WILL GIVE WAY TO VFR
CONDITIONS IN DRIER AIR FOR FRIDAY AFTERNOON. DENSE FOG PER
RADIATIVE COOLING IS POSSIBLE EARLY SATURDAY MORNING.
