NWS Wakefield, VA wrote its last area forecast discussion before the first event at Jun 10, 6:55 PM EST, 15 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WAKEFIELD VA 755 PM EDT WED JUN 10 2009 .SYNOPSIS... A COLD FRONT WILL APPROACH THE AREA FROM THE WEST LATER TODAY...THEN STALL OUT OVER THE REGION TONIGHT. SEVERAL DISTURBANCES WILL THEN MOVE ALONG THE STALLED OUT BOUNDARY FOR THE REMAINDER OF THE WEEK. WEAK HIGH PRESSURE WILL BUILD ACROSS THE AREA ON SATURDAY. && .NEAR TERM /UNTIL 2 AM THURSDAY MORNING/... CIRRUS CLOUDS NOW EXTENDING OVER THE REGION AHEAD OF AN AREA OF STORMS ASSOCIATED WITH A S/W MVG THROUGH THE OH VALLEY. SINCE WEVE SEEN MOCLEAR SKIES OVER THE AREA UNTIL NOW...TEMPS HAVE MADE IT UP INTO THE MID 80S AND DEW PTS ARE CURRENTLY IN THE MID TO UPR 60S. THE STATIONARY FRONT IS LOCATED WELL TO OUR NORTH...THROUGH CNTRL PA AND EXTENDS BACK INTO SOUTHERN IL. AS THE AREA OF CONVECTION OVER OH/WV (AND ASSOCIATED S/W) HEADS THIS WAY THIS EVNG...COVERAGE AND INTENSITY OF STORMS LOOKS TO INCREASE OVER CNTRL/NORTHERN VA DUE TO HEATING AS WELL AS PLENTY OF AVAILABLE MOISTURE. CAPES ARE IN THE RANGE OF 2000 TO 2500 J/KG...LIS ARE UP TO -6...BUT SHEAR IS RATHER WEAK. WOULD THEREFORE EXPECT STORMS TO BE PULSE(Y) IN NATURE...WITH DAMAGING WINDS BEING THE MAIN THREAT (ALTHOUGH WOULDNT RULE OUT IN ISOLD HAIL REPORT IN THERE). UNTIL WE SEE HOW THINGS PLAY OUT IN THE NEXT FEW HRS...HAVE CAPPED POPS OVER THE PIEDMONT BLO LIKELY. THINK THAT THE GREATER THREAT RESIDES NORTH OF OUR CWA IN N VA AT LEAST THROUGH THE EARLY EVNG HRS. WITH LOSS OF HEATING AND AS S/W MVS OFFSHORE...MOST STORMS SHOULD START TO DIMINISH LATE EVNG THROUGH MIDNIGHT...ALTHOUGH WOULDNT BE SURPRISED TO SEE A FEW ONGOING SHRA UP IN NORTHERN AREAS CLOSER TO THE FRNTL BNDRY ESP IF WE GET A LOT OF OUTFLOWS STILL OUT THERE FROM EVNG STORMS. OUR INLAND VA COUNTIES ARE IN A SLIGHT RISK TONIGHT...AND WILL MENTION WIND/HAIL THREAT IN HWO. HEAVY RAIN ALSO A CONCERN WITH SLOW MVG STORMS AND DUE TO THE FACT THAT SOME AREAS HAVE ALREADY SEEN VERY HEAVY RA IN THE PAST WEEK. && .SHORT TERM /2 AM THURSDAY MORNING THROUGH SATURDAY NIGHT/... ON THURS...FRNTL BNDRY PUSHES FURTHER SOUTH TOWARDS THE AREA AND ANOTHER (STRONGER S/W) MVS TOWARDS THE REGION AS WELL (SHOULD BE MVG JUST NORTH OF US). THEREFORE EXPECT DECENT TSRA COVERAGE IN THE AFTN/EVNG HRS. CAPES UP TO 2500 J/KG...LIS AGAIN AROUND -6 AND EVEN MORE MOISTURE EXPECTED...SO SVR STORMS WILL BE A GOOD POSSIBILITY (DAMAGING WINDS AND HAIL MAIN THREATS...SOME BETTER SHEAR EXPECTED BUT NOT ENOUGH TO INCLUDE TORNADO THREAT AT THIS POINT). BNDRY HANGS OUT OVER THE AREA ON FRI...WITH UPR IMPULSES RIDING ALONG IT ALOFT. WILL THEREFORE MAINTAIN CHANCE POPS AGAIN ON FRI AFTN...BUT TOO UNCERTAIN TO SAY WHETHER ONE LOCATION WILL SEE HIGHER CHANCES THAN ANOTHER AT THIS POINT (WILL DEPEND ON TRACK OF IMPULSES AND LOCATION OF FRONT BY THAT TIME). ON SAT IT LOOKS LIKE THE FRONT SHOULD BE JUST TO OUR SOUTH IN THE CAROLINAS SO OUR POPS SHOULD BE SLIGHTLY LOWER (BUT STILL CHANCE IN THE SOUTH CLOSER TO THE BNDRY). KEPT TEMPS RELATIVELY CONSISTENT THURS THROUGH SAT...REMAINING WARM AND MUGGY UNTIL FRONT PUSHES SOUTH OF THE AREA. && .LONG TERM /SUNDAY THROUGH WEDNESDAY/... RATHER UNSETTLED WX CONDITIONS FOR SAT NGT INTO AT LEAST ERLY TUE...AS MID LVL ZNL FLO WILL MAINTAIN A FRNTL BNDRY JUST S OF THE AREA WITH WAVES OF LO PRES MOVNG ALNG IT AND OFF THE CST. THIS WILL RESULT IN SLGT (20) TO SML (30) CHCS FOR SHRAS OR TSRAS ACRS THE REGION. HI PRES WITH DRIER AIR WILL THEN BLD IN FM THE NW FOR LATER TUE THRU WED. MAX TEMPS WILL GENERALLY RANGE FM THE UPR 70S TO MID 80S THRU THE PERIOD. MIN TEMPS WILL RANGE THRU THE 60S TO NR 70 SUN THRU TUE MORNG...AND IN THE UPR 50S TO UPR 60S WED MORNG. && .AVIATION /00Z THURSDAY THROUGH MONDAY/... CURRENT RADAR IMAGERY SHOWS SCT SHRAS AND ISLTD TSTMS SLOWLY MOVING INTO THE WESTERN PORTION OF THE CWA. A WEAK RIDGE IS HELPING TO SLOW THEIR FORWARD PROGRESS AND THE SHRAS/TSTMS ARE EXPECTED TO WEAKEN WITH THE LOSS OF DAYTIME HEATING. LEFT CB IN FOR RIC AS REMNANTS GET THERE LATER THIS EVENING. MAIN CONCERN OVERNIGHT WILL BE PATCHY FOG. LIFR CIGS (AND POSSIBLY VIS) WILL DEVELOP OVERNIGHT AT SBY. EXPECT CIGS AT RIC TO DROP TO IFR BY 08Z AS MOISTURE FROM THE REMNANT SHRAS WILL HELP TO SATURATE THE LOWER LVLS. ESLWHERE...EXPECT TO SEE MVFR AS PATCHY FOG DEVELOPS DUE TO RADIATIONAL COOLING. CIGS AND VIS WILL LIFT SHORTLY AFTER SUNRISE RETURNING TO VFR CONDS LATE MORNING ACROSS THE FA. VFR CONDS EXPECTED THROUGH THE WEEKEND. LOCAL MVFR/IFR CONDS DUE TO SCT SHRAS/TSTMS THROUGH FRI AS SEVERAL UPR LVL DISTURBANCES MOVE ALONG A SLOWLY MOVING FRONTAL BOUNDARY THAT WILL BE MAKING ITS WAY ACROSS THE REGION. && .MARINE... NO HEADLINES IN THE SHRT TERM TNGT THRU FRI. LGT AND VARIABLE WNDS THIS EVENG/TNGT WILL BECOME SE OR S DURING THU AND INCRS TO 10 TO 15 KT.
