AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON WV
330 PM EDT THU AUG 9 2007
.SYNOPSIS...
AN UPPER DISTURBANCE WILL FIRE OFF THUNDERSTORMS THIS EVENING...
PARTICULARLY IN SOUTHEAST OHIO AND NORTHERN WEST VIRGINIA. A WEAK
COOL FRONT WILL MOVE SOUTHEAST LATE TONIGHT AND EARLY FRIDAY. HIGH
PRESSURE BUILDS IN FOR THE WEEKEND.
&&
.NEAR TERM /THROUGH FRIDAY NIGHT/...
STARTING TO SEE THE SALT AND PEPPER STORMS LIGHTING UP THE 88D IN
THIS UNSTABLE AIRMASS. NONE SEVERE YET...BETTER
FORCING/ORGANIZATION STILL LIES TO THE NORTH.
STILL BELIEVE THAT MORE ORGANIZED SEVERE THREAT WILL NOT ARRIVE
UNTIL AROUND 00Z AND AFTER...AS VORT CENTER OVER INDIANA APPROACHES
THE OHIO RIVER. SHOULD STILL BE ENOUGH INSTABILITY...EVEN AFTER
SUNSET...TO PRODUCE LARGE AND WET STORMS. PRIMARY SEVERE THREAT
WILL LIKELY BE WIND DAMAGE FROM WET DOWNBURSTS...WITH DEEP WESTERLY
FLOW ALOFT. FREEZING LEVEL/WBZ HEIGHTS TOO HIGH FOR MUCH HAIL.
STORMS WILL ALSO PRODUCE FREQUENT CLOUD TO GROUND LIGHTNING STRIKES
AND TORRENTIAL DOWNPOURS.
MAIN PUSH OF CONCENTRATED SHRA/TSRA WILL LIE ALONG OUR NORTHERN
BORDER...ALONG PERSISTENT SURFACE BOUNDARY AND OUTFLOW FROM MORNING
MCS. KEPT LIKELY POPS IN THIS AREA. LESSER POPS TO THE SOUTH.
THIS AREA WILL NOT GET ACCESS TO THE LOW LEVEL FORCING FURTHER
NORTH...AND FORCING ALONG APPROACHING FRONTAL BOUNDARY LATER AT
NIGHT WILL BE MUCH WEAKER.
FRONT WILL BE MEANDERING THROUGH AREA AT 12Z. THIS WILL LIKELY BE
ONE OF THOSE SITUATIONS WHERE THE FRONT WILL MOVE THROUGH ALOFT
TONIGHT...BUT REQUIRE DAYTIME MIXING TO HOP INTO THE MOUNTAINS AT
THE SURFACE. KEPT LOW CHANCE POPS EAST OF CRW/PKB ON FRIDAY FOR
SCATTERED ACTIVITY THAT MANAGES TO SURVIVE THE NIGHT...AS WELL AS
DAYTIME CONVECTION. IN ANY CASE...RAINS SHOULD BE DONE BY 00Z AS
FRONT EXITS AND DRIER AIR IS ABLE TO MIX IN. FRIDAY NIGHT LOOKS
QUIET AND MORE COMFORTABLE. DENSE FOG...AT LEAST IN VALLEYS...IS A
POSSIBILITY.
KEPT RECENT PATTERN OF USING MET TEMPS AT NIGHT AND A MET/MAV BLEND
DURING THE DAY.
&&
.SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/...
MODELS SHOW THE UPPER HIGH CENTER BUILDING OVER THE CENTER OF THE
NATION THIS WEEKEND. DEVELOPING NORTHWEST FLOW ALOFT WILL ALLOW SOME
MINOR COOLING FOR THIS WEEKEND BEHIND THE FRIDAY FRONT. STILL...MOST
OF THE COOLER AIR WILL REMAIN NORTH AND EAST OF OUR AREA...WITH
TEMPERATURES STILL ABOVE NORMAL THIS WEEKEND...AROUND 90 DEGREES.
MORE IMPORTANTLY...MUCH DRIER AIR WILL FLOW IN AS HIGH PRESSURE
BUILDS SOUTH AND EAST FROM THE UPPER MIDWEST. WITH THE DRIER
AIR...IT WILL FEEL MORE COMFORTABLE..AND EVEN A BIT COOLER AT NIGHT
DUE TO THE DRIER AIR. EVEN SO...MAV TEMP GUIDANCE CONTINUES TO LOOK
A BIT TOO WARM ON DAYTIME TEMPS...AND TOO COOL ON NIGHT TIME TEMPS.
TOOK A BLEND OF THE MAV AND MET.
&&
.LONG TERM /MONDAY THROUGH THURSDAY/...
MODELS IN GOOD AGREEMENT ON THE STRONG AND WARM UPPER HIGH CENTERED
OVER THE CENTER OF THE NATION THROUGH THIS PERIOD. WE WILL BE IN
NORTHWEST FLOW ALOFT AROUND THE HIGH...SO THAT ONE WEAK FRONT MAY
DROP INTO OUR NORTHERN AREAS LATE MONDAY BEFORE DISSIPATING...AND
ANOTHER ON THURSDAY. STILL...WE WILL BE TOO CLOSE TO THE UPPER HIGH
FOR ANY SIGNIFICANT PRECIP WITH THESE FRONTS. THUS...MOST OF OUR
AREA REMAINS DRY THROUGH THIS PERIOD WITH TEMPERATURES ABOVE
NORMAL...BUT NOT AS HOT AS THE CURRENT HEAT.
&&
.AVIATION /18Z THURSDAY THROUGH TUESDAY/...
CONDITIONS ACROSS MOST OF THE REGION REMAINED IN THE VFR/MVFR
CATEGORY. HOWEVER...EKN AND OTHER FAVORED MOUNTAIN VALLEY LOCATIONS
HAD BECOME IFR/LIFR WITH FOG AND ASSOCIATED LOW CLOUDS.
THE FOG AND LOW CLOUD SHOULD DISSIPATE SHORTLY AFTER SUNRISE WITH
CONDITIONS IMPROVING TO VFR ACROSS THE ENTIRE AREA.
EXPECT THUNDERSTORMS WILL ONCE AGAIN DEVELOP DURING THE LATE MORNING
AND EARLY AFTERNOON HOURS ACROSS SOUTHEAST OHIO AND NORTHERN WEST
VIRGINIA...WITH THE RAIN CHANCES INCREASING SOUTHWARD WITH TIME.
IFR CONDITIONS ARE POSSIBLE NEAR THESE STORMS...WITH VFR CONDITIONS
EXPECTED ELSEWHERE.
THUNDERSTORMS SHOULD DECREASE IN AREAL COVERAGE AFTER SUNSET. A
COLD FRONT AND ASSOCIATED THUNDERSTORMS WILL THEN PUSH SOUTHEAST
INTO THE REGION TONIGHT. ONCE AGAIN...IFR CONDITIONS WILL BE
POSSIBLE NEAR THESE STORMS.
OUTSIDE OF STORMS...THERE MAY BE A FEW AREAS IN THE MOUNTAINS WHERE
CONDITIONS DETERIORATE INTO THE IFR CONDITION.
AVIATION OUTLOOK 12Z FRIDAY THRU MONDAY...THE BEST CHANCE FOR
THUNDERSTORMS...AND IFR CONDITIONS...WILL LIE ACROSS EASTERN WEST
VIRGINIA FRIDAY MORNING AS A COLD FRONT PUSHES THROUGH.
