AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON WV
ISSUED BY NATIONAL WEATHER SERVICE PITTSBURGH PA
801 PM EDT SUN JUL 1 2012
.SYNOPSIS...
NORTHWEST FLOW CONTINUES...WITH HEAT PREVAILING AND THUNDERSTORM
CHANCES PERSISTING THROUGH THE WEEK.
&&
.NEAR TERM /THROUGH MONDAY/...
FORECAST BROUGHT TO YOU BY RLX AT PBZ. THANKS TO PBZ FOR THE
ACCOMMODATIONS.
CONVECTIVE COMPLEX ALREADY UNDERWAY NORTHWEST OF CWA IN NORTHERN
ILLINOIS/INDIANA...AND LOOKS TO BE THE PROBLEM CHILD FOR THIS
EVENING AND TONIGHT. HIGHLY UNSTABLE ENVIRONMENT GIVING CAPE OVER
4000J/KG ACROSS MUCH OF THE AREA...ALTHOUGH MAY BE A LITTLE
INFLATED WITH NAM DEWPOINT BIASES. REGARDLESS...PLENTY OF
INSTABILITY TO BE FOUND...FOR PROPAGATING MCS TOWARDS THE MIDDLE
OHIO VALLEY AND CENTRAL APPALACHIANS. STEERING WINDS ARE ABOUT
HALF THEY WERE A COUPLE DAYS AGO...AND DO NOT EXPECT AS QUICK OF A
FORWARD MOTION. BEST CAPE IN HAIL GROWTH ZONE...SO COULD SEE HAIL
THREAT ALONG WITH ANOTHER WIND THREAT. WITH THE CONVECTION ALREADY
BEGUN NORTHWEST OF HERE...THINK IT IS ONLY A MATTER OF TIME
BEFORE THE NEXT ROUND OF WEATHER FOR OUR AREA. WILL TRY TO UPDATE
AS MUCH AS POSSIBLE.
ISSUED A HEAT ADVISORY FOR MUCH OF THE LOWLANDS MONDAY. NUMBERS
MAY NOT MAKE IT TO THE 100 NEEDED IN THE HEAT INDEX...BUT FIGURE
THAT WITH MANY PEOPLE IN THE AREA WITHOUT POWER...IT IS MORE THAN
JUSTIFIED AS WEST VIRGINIA AND OHIO TRY TO GET BACK ON THEIR FEET.
LEFT THE MOUNTAIN COUNTIES AND VIRGINIA COUNTIES OUT FOR NOW WITH
LOWER TEMPERATURES.
&&
.SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY/...
KEEPING THIS SHORT... HEAT CONTINUES ALTHOUGH MAYBE A COUPLE
NOTCHES BELOW NEAR TERM VALUES...WITH THUNDERSTORM CHANCES
CONTINUING IN THE PREVAILING NORTHWEST FLOW REGIME. CANNOT LEAVE
POPS OUT DURING THE OVERNIGHT IN GOOD FAITH GIVEN THE VOLATILE
PATTERN...BUT HIGHEST CHANCES WILL BE IN THE AFTERNOON AND EVENING
HOURS EACH DAY.
&&
.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
EXTENDED FORECAST FEATURES DIFFERENCES IN MODEL GUIDANCE THAT
LEADS TO DIFFERENCES IN TIMING AND PLACEMENT OF ANY PRECIPITATION.
ALL THINGS CONSIDERED...GOING WITH HPC GUIDANCE WHICH USES A BLEND
OF THE ECMWF AND GFS. CWA STAYS ON THE EASTERN PERIPHERY OF THE
RIDGE KEEPING THE HOT TEMPERATURES IN PLACE...BUT ALSO PROVIDES SEVERAL
DISTURBANCES KEEPING THE LOW CHC POPS IN PLACE.
&&
.AVIATION /00Z MONDAY THROUGH FRIDAY/...
IMPENDING CONVECTION IN THE TAFS WITH TEMPO TSRA AND WIND
GUSTS...IN SOME CASES ABOVE 45KTS. FIGURE THIS WILL BE IN PLACE
FOR A FEW MORE HOURS BEFORE CONVECTION WANES. CLEARING EXPECTED
LATE TONIGHT WHICH WOULD BRING ANY TERMINALS THAT RECEIVE RAIN TO
LIFR CONDITIONS QUICKLY. QUESTION WILL BE BKW AND SPLIT THE
DIFFERENCE WITH IFR VIS LATE.
MORE CUMULUS EARLY MONDAY...WITH CONVECTION IN THE AFTERNOON AND
EVENING.
FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 00Z TUESDAY...
FORECAST CONFIDENCE: MEDIUM.
ALTERNATE SCENARIOS: MAY NEED TO ADJUST CONVECTION TIMING.
FOG TIMING EVOLUTION COULD VARY.
