AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BLACKSBURG VA
227 PM EDT THU AUG 9 2007
.SYNOPSIS...
A COLD FRONT WILL PUSH THROUGH OUR PERSISTENT AREA OF HIGH
PRESSURE ON FRIDAY. ISOLATED TO SCATTERED SHOWERS AND STORMS WILL
ACCOMPANY IT. COOLER AND LESS HUMID CONDITIONS WILL BE COMMON
THROUGH THE WEEKEND.
&&
.NEAR TERM /THROUGH FRIDAY/...
NOT A LOT OF CHANGE TO GOING FORECAST WITH YET ANOTHER WARM/MUGGY
OVERNIGHT SIMILAR TO THE PAST FEW GIVEN MOIST DEW POINTS AND RIDGING
OVERHEAD. BEST SUPPORT FOR CONVECTION MAINLY ACROSS THE NORTH/NE
THIS EVENING UNDER PASSING S/W AND MCS REMNANT. HOWEVER SOME LIFT
MAY TEND TO INTERACT WITH WEAKNESS ACROSS THE PIEDMONT PER NAM BUT
IFFY IN DEEP WESTERLY FLOW. OTRW WILL RUN WITH MAINLY ISOLATED POPS
EARLY TONIGHT SINCE LOTS OF SHALLOW INSTABILITY AROUND UNDER DRY AIR
WITH LIMITED UPPER SUPPORT. NEXT UPSTREAM PREFRONTAL S/W AXIS WILL
HEAD QUICKLY SE OVERNIGHT REACHING THE WESTERN SLOPES LATE. THIS MAY
BRING ANOTHER BAND OF WEAKENING CONVECTION IN LATE SO KEEPING 20/30
POPS NW LATE. WILL AGAIN FOLLOW CLOSER TO MUGGY MET LOWS WITH MOST
IN THE 70S OVERNIGHT.
UPSTREAM COLD FRONT SHOULD JUMP INTO A WELL PRONOUNCED LEE TROF EAST
OF THE BLUE RIDGE FRIDAY. WITH WELL MIXED/DEEP W/NW FLOW MOISTURE
APPEARS QUITE SHALLOW ALONG THE FRONT AS BEST LIFT SHIFTS INTO NC.
SINCE STILL LOTS OF HEATING ONGOING IN HIGH THETA-E ENVIRONMENT WONT
PULL POPS ENTIRELY EXCEPT EASTERN SLOPES GIVEN DOWNSLOPE. OTRW
THINKING 20 TO POSSIBLY 30 POPS WESTERN SLOPES WHERE MODELS HAVE
BEST RH. 850 MB TEMPS A BIT COOLER FRIDAY IN RESPONSE TO LOWERING
HEIGHTS AND NW FLOW. HOWEVER EXPECT DOWNSLOPE WARMING TO LIKELY
BOOST HIGHS BACK CLOSE TRIPLE DIGITS PIEDMONT BUT A BIT DRIER WHICH
SHOULD PRECLUDE MUCH OF AN ADVISORY THREAT. OTRW BUMPED UP HIGHS
WELL INTO THE 80S MOUNTAINS AND MID/UPPER 90S EAST ALTHO STILL BELOW
QUITE WARM MAV MOS.
&&
.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/...
FRIDAY EVENING THERE STILL MAY BE SOME HIT OR MISS SHOWERS AND
STORMS IN THE MOUNTAINS...AND IN THE FAR SOUTHEAST UNTIL SHORTLY
AFTER SUNSET. FROM PAST THAT POINT WE WILL CARRY A DRY FORECAST
THROUGH THE WEEKEND AS RELATIVELY COOLER AND DRIER AIR MOVES INTO
BEHIND THE FRONT. READINGS FOR HIGHS AND LOWS SHOULD BE AT...OR
SLIGHTLY BELOW...NORMAL CONDITIONS FOR THIS TIME OF THE YEAR.
&&
.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
WHILE THE UPPER RIDGE WILL MAKE A BIT OF AN ATTEMPT TO BUILD BACK
OVER THE REGION BY EARLY NEXT WEEK...ITS INFLUENCE WILL NOT BE AS
STRONG HAS WHAT HAS BEEN EXPERIENCED THIS CURRENT WEEK. THE RESULT
WILL BE A PREDOMINATE NORTHWEST FLOW ALOFT ACROSS THE REGION
ALLOWING FOR A BETTER POTENTIAL OF WEAK FRONTS TO DIP EITHER INTO
OR THROUGH THE REGION...ALONG WITH THUNDERSTORM COMPLEXES IN THE
OHIO VALLEY TO PROGRESS INTO MAINLY WESTERN PARTS OF THE REGION.
WILL BE FOLLOWING HPC/S SOLUTION REGARDING THIS SCENARIO. THIS
EQUATES TO ISOLATED THUNDERSTORM POTENTIAL MONDAY THROUGH TUESDAY
WITH ONE WEAK COLD FRONT MOVING THROUGH THE REGION. AND THEN AGAIN
ON THURSDAY ISOLATED TO SCATTERED STORMS ARE EXPECTED WITH ANOTHER
FAST MOVING WEAK COLD FRONT. TEMPERATURES NEXT WEEK LOOK TO BE
WITHIN 2 TO 3 DEGREES EITHER SIDE OF NORMAL...BOTH FOR THE HIGHS
AND LOWS.
&&
.AVIATION /18Z THURSDAY THROUGH TUESDAY/...
THERE WILL BE ISOLATED THUNDERSTORMS THIS AFTERNOON IN THE
MOUNTAINS AND ACROSS THE NORTH. HEAVY RAIN WITH THESES STORMS
WOULD CREATE MVFR TO IFR VISIBILITIES...BUT THE CHANCE IS TOO LOW
TO INCLUDE IN THE BODY OF THE TAFS EXCEPT FOR LWB AND BLF WHERE
WILL INCLUDE VCTS OR TEMPO MENTION. OTRW VFR IN PERIODS OF BKN
4-6K CU WEST AND SCT CU OUT EAST. STORMS MAY PERSIST INTO EARLY
THIS EVENING BEFORE FADING OVERNIGHT WITH LOSS OF HEATING. COULD SEE
ANOTHER COMPLEX OF STORMS MAY A RUN AT LWB LATE TONIGHT BUT TOO
IFFY TO INCLUDE. AGAIN LOOKING AT PATCHY FOG/HAZE LATE TONIGHT
WITH IFR/LIFR AT LWB PENDING DEGREE OF DEBRIS CLOUDS. OTRW MAINLY
VFR...OCNL MVFR LYH/DAN TOWARD 12Z.
THE CHANCE OF SHOWERS AND THUNDERSTORMS REMAINS FRIDAY AND FRIDAY
EVENING WITH A FRONT. HOWEVER GIVEN DEEPENING WEST/NW FLOW EXPECT
ONLY ISOLATED COVERAGE AT BEST DURING THE VALID TAF PERIOD INTO
FRIDAY AFTERNOON. MAY SEE MORE LOW CLOUDS NW PER UPSLOPE FLOW
BEHIND THE FRONT OTRW VFR. THE FRONT WILL BE SOUTH OF THE FORECAST
AREA BY SATURDAY MORNING. DRY...VFR WEATHER IS EXPECTED THROUGH
THE WEEKEND INTO EARLY NEXT WEEK.
