Area forecast discussion, Jun 23, 9:40 AM EST, 4 hours 25 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BLACKSBURG VA 1040 AM EDT WED JUN 23 2004 .SHORT TERM (THIS AFTERNOON)... TODAY/S FORECAST WITH CATEGORICAL POPS FOR ALL AREAS AT SOME POINT TODAY LOOKS RIGHT ON TRACK. WEAK SFC FRONT HAS MOVED SLIGHTLY FURTHER SOUTHEAST THIS MORNING AND IS NOW ACROSS SRN WV. A WEAK SHORT WAVE IS GENERATING A LARGE AREA OF SHOWERS THAT WILL BE MOVING ACROSS MOST OF THE NRN 2/3 OF THE CWA LATE MORNING INTO EARLY AFTERNOON. MEANWHILE...THE SERN 1/3 OF THE CWA...MAINLY NW NC AND SOUTH SIDE VA...IS GETTING SOME HEATING AND WILL BE MORE UNSTABLE WHEN THIS AREA OF SHOWERS IS MOVING IN THIS AFTERNOON- I EXPECT TO SEE THUNDERSTORMS BY THEN. THAT AREA IS UNDER A SLIGHT RISK OF SEVERE THUNDERSTORMS...WITH MAINLY UNIDIRECTIONAL WINDS THAT ARE STRENGHTENING WE COULD SEE ORGANIZED LINES OF CONVECTION WITH A THREAT OF WIND DAMAGE OR HAIL. HAVE MADE SOME ADJUSTMENTS TO THE WEATHER TIMING...AND LOWERED MAX TEMPS WHERE THE PRECIP IS ALREADY OCCURRING. NO OTHER SIGNIFICANT CHANGES TO THE FCST. JJ PREVIOUS DISCUSSION BELOW SHORT TERM (THROUGH THURSDAY NIGHT)... WEAK FRONT SITUATED FROM NE KY INTO WRN WVA THE MAIN PLAYER TODAY AS IT SLOWLY FOLDS SWD INTO THE CWA THIS AFTN. LIFT ALONG THE FRONT TO BE ENHANCED BY WAVE OF LOW PRES PROGGED TO RIDE UP THE BOUNDARY LATER ON IN RESPONSE TO RIGHT REAR OF SPEED MAX PASSING THRU THE OHIO VALLEY. QUESTION IS HOW FAR S 85H FRONT WILL GET AND DEGREE OF DEEP CONVECTION ESPCLY OVER THE W WHERE FFG VALUES REMAIN RATHER LOW. BOTH ETA/GFS SUGGEST BEST LIFT/FOCUS ALONG/W OF THE WRN SLOPES EARLY ON ALONG 85H THETA-E GRADIENT...THEN JUMPING EWD TO E OF THE BLUE RIDGE THIS AFTN WHERE BETTER SHOT AT SVR WIND POTENTIAL LOOKS TO OCCUR AS WAVE/INSTAB TAKES SHAPE. APPEARS FFG ENOUGH TO HANDLE AVERAGE QPF OF ABOUT AN INCH OFF GUIDANCE BUT CONCERN WITH SHORT LINES OF TRAINING TSRA PER UNIDIRECTIONAL SW FLOW ALOFT/DIFFLUENCE ALOFT AND TROPICAL PWATS. GIVEN LOW CONFIDENCE IN ANY ONE AREA SEEING ENOUGH TO CAUSE MORE THAN LOCALIZED FLOODING...WILL OPT AGAINST A FFA TODAY AND INCLUDE HEAVY RAIN MENTION IN ZFP/SPS. OTRW POPS INCREASING FROM W TO E THRU THE AFTN WITH MOST EVENTUALLY REACHING LIKELY/CAT SCENARIO LATER. TEMPS GNRLY CLOSE TO MAV ESPCLY E WHERE SHOULD SEE SOME SUN THIS MORNING. WAVE MOVES E THIS EVENING ALLOWING FOR A QUICK SHOT OF DRY ADVECTION BEHIND COLD FRONT DROPPING S INTO THE CAROLINAS. ETA APPEARS QUITE FAST IN EJECTING SHRA OUT OF THE E AROUND MIDNGT...SO WILL CONT TO HOLD AT LEAST A LOW CHC INTO THE EARLY MORNING HOURS AFTER SOME EARLY LIKELYS SE TIER. DRIER AND SOMEWHAT LESS HUMID AIR IN STORE THU AS WEAK RIDGE SLIDES EWD BEHIND EXITING S/W EARLY THU. THINK MOST SHRA GONE BY DAYBREAK THU SO WILL PULL CHCS AND GO PARTLY/MSTLY SUNNY WITH SOME CU/CI ARND. TEMPS STILL QUITE WARM HOWEVER GIVEN DOWNSLOPE AND MORE INSOLATION ON THU. && LONG TERM (FRIDAY THROUGH TUESDAY)... UPPER TROFFINESS TO REMAIN ACTIVE EARLY ON AS DRY REPRIEVE IN SHORT ORDER AHEAD OF NEXT UPSTREAM S/W TROF AND BACKING FLOW BY FRI. THIS SHOULD AGAIN ALLOW RESIDUAL DEEP RH TO THE S TO SPILL BACK NWD FRI BEFORE NEXT COLD FRONT CATCHES UP ON SAT. ETA/CANADIAN AGAIN FASTER WITH INIT SLUG OF MOISTURE SO WILL UP/ADD POPS TO ALL ZONES FRI AND CONT CHCS FRI EVENING THRU SAT AS FRONT MOVES THRU. LOOKS LIKE SIMILAR TO THE LAST FRONT THAT RH WILL GET SHUNTED S ON SUNDAY WITH THE GFS HINTING THAT SURFACE RIDGING MAY BE ENOUGH TO HOLD POPS S INTO EARLY WEEK. SINCE THIS HAS BEEN HARD TO DO ALL SEASON...PLAN TO JUST CUT NRN ZONES BACK TO SLIGHT CHCS MON/TUE WHILE LEAVING DIURNAL COVERAGE S UNCHANGED. MAY ALSO UP TEMPS AHEAD OF THE FRONT SAT AND EARLY WEEK PENDING SUNSHINE OTRW NEAR SEASONAL LEVELS EXPECTED. && AVIATION... EXPECT CONDITIONS TO APPROACH MVFR TOWARDS DAYBREAK...WITH RNK HAVING THE BEST CHANCE OF SEEING ANY RAINFALL BY 12Z. CURRENT VFR CLOUDS WILL BE LOWERING TOWARDS MVFR BY MORNING...WITH AREAS OF PATCHY MVFR FOG ALSO BEING ENCOUNTERED. FRONTAL SYSTEM MOVING TOWARDS THE CWA WILL CONTINUE TO SPREAD MOISTURE AND LOWER CLOUDS ACROSS THE ENTIRE CWA TODAY. AREAS THAT RECEIVE RAINFALL TODAY WILL HAVE BEST CHANCE FOR MVFR FOG FORMATION AFTER 00Z TONIGHT. && .RNK WATCHES/WARNINGS/ADVISORIES... NC...NONE. VA...NONE. WV...NONE. && AVIATION: 16 SHORT TERM: 16 LONG TERM: JH
