What forecasters said that day
The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Blacksburg, VA wrote its last area forecast discussion before this severe thunderstorm warning went out at May 13, 10:53 AM EDT, 3 hours 47 minutes earlier.
Area forecast discussion, May 13, 10:53 AM EDT, 3 hours 47 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BLACKSBURG VA 1053 AM EDT FRI MAY 13 2011 .SYNOPSIS... A NEARLY STATIONARY FRONTAL BOUNDARY ACROSS THE CENTRAL AND SOUTHERN APPALACHIANS WILL LINGER ACROSS THE AREA INTO TONIGHT. THIS FRONT WILL BE CAUGHT UP TO BY A STRONG LOW PRESSURE AREA AND COLD FRONT THIS WEEKEND. THE FRONT MOVES EAST OF THE AREA SUNDAY WITH COOLER WEATHER EXPECTED EARLY NEXT WEEK. && .NEAR TERM /THROUGH TONIGHT/... MAIN ISSUE FOR THIS MORNING WILL BE THE AFFECT OF CLOUD COVER ON TEMPERATURES FOR LOCATIONS EAST OF THE BLUE RIDGE. EXPECT THAT THE NORTH CAROLINA PIEDMONT AND MUCH OF SOUTHSIDE VIRGINIA WILL REMAIN SOCKED WITH LOW CLOUDS THROUGH MOST OF THE DAY...AND HAVE THEREFORE LOWERED AFTERNOON HIGHS BY SEVERAL DEGREES TO THE UPPER 60S TO LOW 70S. THIS MAY STILL NOT BE ENOUGH FOR SOME LOCATIONS. CONVERSELY...LOW CLOUD COVER IS ERODING WEST OF THE BLUE RIDGE... ESPECIALLY ACROSS THE MOUNTAIN EMPIRE REGION AND THE NEW RIVER VALLEY. HEATING TAKING PLACE THIS MORNING IS ONCE AGAIN PRIMING THE ATMOSPHERE FOR MORE SHOWER AND THUNDERSTORM ACTIVITY THIS AFTERNOON AND EVENING. AS WITH YESTERDAY EVENING...EXPECT THAT A FEW THUNDERSTORMS WILL AGAIN BE SEVERE...WITH LARGE HAIL AND PERIODS OF VERY HEAVY RAIN AS THE MAIN THREATS. .PREVIOUS DISCUSSION... GOING WITH RADAR/SAT TRENDS EARLY THIS MORNING FOLLOWED BY A BLEND OF THE CMC/GFS/ECMWF. THE 00Z GFS APPEARS TO QUICK WITH THE UPPER SYSTEM ACROSS THE CENTRAL PLAINS THIS MORNING BUT HIGHLIGHTS SOME QPF ALONG THE BLUE RIDGE WHICH FITS THE OTHER MODELS CONVERGENCE PATTERN WITH A LIGHT SE FLOW. THE PATTERN OF THE UPPER RIDGE WITH A STALLED OUT WEAK BOUNDARY ACROSS THE CENTRAL/SRN APPS THIS MORNING WILL REMAIN THIS MORNING BUT A STRONGER UPPER VORT CUTTING ACROSS THE OHIO VALLEY WILL BREAK THE RIDGE DOWN SOME WITH THE UPPER LOW PUSHING EAST INTO THE MID MISSISSIPPI VALLEY THIS EVENING. FOR EARLY THIS MORNING WE ARE DEALING WITH DENSE FOG ACROSS PORTIONS OF SW VA/SE WV AND NW NC AS SOME CLEARING ABOVE THE BL HAS SET THIS UP WELL...WITH WET GROUND. AREA OBSERVATIONS HAVE FLUCTUATED BETWEEN 1/4SM TO 1SM+...SO ATTM...WILL NOT HAVE A DENSE FOG ADVISORY BUT KEEP THE SPECIAL WEATHER STATEMENT GOING. THE FOG AND LOWER CLOUDS WILL BE SLOWER TO CLEAR IN THE EAST AGAIN THIS MORNING BUT WE SHOULD SEE A TRANSITION TO MORE SOUTH- SOUTHWEST FLOW ABOVE 925 MB WHICH SHOULD LIFT THE CIGS HIGHER THAN THURSDAY. THE SHORTWAVE TRAVERSING KY THIS MORNING WILL HELP INITATE CONVECTON TOWARD MID TO LATE MORNING IN THE WEST WHILE NW FLOW FURTHER EAST AND WEAK WAVE COULD BRING SCT SHRA/TSRA TO AREAS EAST OF ROANOKE. GIVEN THIS FACTOR AND BETTER UPPER LEVEL LIFT...WILL HAVE HIGHER POPS TODAY...WITH HIGH CHANCE TO LIKELYS. PWATS WILL REMAIN VERY HIGH...AND WILL HAVE TO MONITOR ANY ORGANIZED CONVECTION AND TRAINING POTENTIAL FOR FLASH FLOOD CONCERNS. ATTM...WILL MENTION FFA THREAT IN THE HWO AS TOO EARLY ON WHERE THIS SETUP WILL BE. LOWEST FFG AND AREAS OF CONCERN WOULD BE ALONG AND WEST OF THE BLUE RIDGE...ESPECIALLY THE NEW RIVER VALLEY AND GREENBRIER VALLEY. SHOULD SEE TEMPS SIMILAR TO THURSDAY IN THE WEST...ALTHOUGH NOT QUITE AS WARM IN BLF AS EXPECT MORE CLOUDS/CONVECTION EARLIER TODAY. SHOULD ALSO BREAK THE WEDGE OUT EAST AND WARM THINGS UP INTO THE LOWER TO MID 70S. TONIGHT...WILL KEEP POPS IN THE HIGH CHANCE TO LIKELY AS UPPER DIFLUENCE INCREASES AHEAD OF UPPER LOW. LOWS TONIGHT WILL BE AGAIN MILD WITH MAINLY UPPER 50S TO MID 60S. && .SHORT TERM /SATURDAY THROUGH MONDAY NIGHT/... A COLD FRONT WILL CROSS SAT NIGHT...AND SOMEWHAT DRIER AND COOLER AIR WILL ARRIVE INTO SUNDAY. STORMS WILL BE NUMEROUS AS THE FRONT APPROACHES SATURDAY AND ALREADY HARD HIT AREAS IN TERMS OF WATER MAY HAVE WATER PROBLEMS SATURDAY. SHOWERS AND THUNDERSTORMS MAY NOT BE AS WIDESPREAD NOR AS STRONG EARLY NEXT WEEK AS WHAT HAS BEEN OBSERVED DURING MUCH OF THIS WEEK. DESPITE THIS...COLD POOL ALOFT AND PROXIMITY OF UPPER LOW WILL BE RESPONSIBLE FOR SCATTERED SHOWERS EVEN WITH A THICK CEILING IN PLACE. PWATS ARE MUCH LOWER SUNDAY AND ESPECIALLY MONDAY...SO SOME OF THE LIKELY POPS NEAR THE END OF THE SHORT TERM MAY NEED TO BE LOWERED. HOWEVER...CURRENT 0Z GFS HAS A SHRTWV PASSING RIGHT OVER THE CWA ON MONDAY...WHEREAS THE OLD ECMWF TOOK THIS SAME DISTURBANCE SOUTH AND WEST OF THE REGION. THE ECMWF SOLUTION WOULD SUGGEST SMALLER CHANCES FOR PRECIP. SOME IMPRESSIVELY CHILLY AIR FOR THIS TIME OF YEAR FALLS INTO KY AND TN JUST TO OUR WEST. THE OP GFS ALLOWS THIS COLDER AIR TO MAKE BETTER EASTWARD PROGRESS INTO OUR REGION...BUT WILL CONTINUE TO FOLLOW THE ECMWF WHICH HAS BEEN MORE ACCURATE WITH THIS REGIME OVER THE PAST SEVERAL DAYS. && .LONG TERM /TUESDAY THROUGH THURSDAY/... OMEGA BLOCK OVER THE ROCKIES WILL BECOME A REX BLOCK WITH HIGHER HEIGHTS JUST SOUTH OF HUDSON BAY NORTH OF A CLOSED LOW OVER THE EAST CENTRAL CONUS...THE STACKED LOW THE FOCUS FOR OUR WEATHER FOR MOST OF THE WEEK. BOTH THE ECMWF AND THE GFS DUMP ADDITIONAL DISTURBANCES INTO THE CLOSED UPPER LOW...RESULTING IN PERIODS OF TIME WHERE THE RAIN CHANCES WILL BECOME HIGHER DURING THE 4 DAY PERIOD. ATTM IT APPEARS THE GREATEST THREAT FOR PRECIP AND HIGHEST QPF WILL BE EARLY IN THE WEEK...ESPECIALLY MONDAY AND TUESDAY...WHEN THE LOW IS PRACTICALLY OVHD...THEN A DECREASING TREND AS THE UPPER LOW FILLS AND DRIFTS SLOWLY NORTHWARD FOR THE LATTER HALF OF THE WEEK. TEMPERATURES ARE EXPECTED TO REMAIN RELATIVELY COOL MONDAY...TUESDAY...AND WEDNESDAY DUE TO THE ABUNDANT CLOUD COVER AND SHOWERS...THEN BEGIN THE TRANSITION TO WARMER NUMBERS FOR THE LATTER HALF OF THE WEEK. && .AVIATION /15Z FRIDAY THROUGH TUESDAY/... AVIATION CONCERNS EARLY WILL BE LOW CIGS/VSBYS AT ALL SITES BUT BLF. THE MODEL SOUNDINGS AND TRENDS SUGGEST IMPROVEMENTS TO VFR AT LWB/BCB SOONER IN THE 14-16Z TIME FRAME...WITH ROA/LYH/DAN SCOURING OUT OF THE MVFR OR WORSE RANGE MIDDAY TO EARLY AFTN. OTHER FOCUS WILL BE ON CONVECTION AND HOW WIDESPREAD IT WILL BE. MODELS SUGGEST AT LEAST 50 PERCENT COVERAGE OF STORMS THIS AFTN INTO THE EVENING BUT PLACEMENT AND TIMING IT IS STILL TOO EARLY FOR ADDING THUNDER TO THE TAFS. WILL SEE SOME SHOWERS AROUND THIS MORNING NEAR BLF/LWB WITH A BETTER THREAT THIS AFTN. HAVE SHOWERS REDUCING VSBYS TO MVFR/IFR AFTER 20Z WITH CIGS DROPPING TO LOW END VFR INTO MVFR RANGE. STARTING THIS EVENING...MODELS KEEP THE RAIN SHOWERS AND STORMS AROUND...ALTHOUGH THE FASTER GFS SHUNTS PRECIP FURTHER EAST OVERNIGHT. WILL LEAN TOWARD A SLOWER SOLUTION BUT WILL SEE IFR CIGS/VSBYS OVERNIGHT AT MOST LOCATIONS. CONFIDENCE IS HIGH ON SUB VFR LATE TONIGHT GIVEN HIGH MOISTURE CONTENT IN THE LOW LVLS. THE SLOW MOVING UPPER LOW ACROSS THE MISS VALLEY WILL MOVE TO THE EAST INTO THE WEEKEND BUT KEEPING THE AREA WITH A DAMP/CLOUDY PERIOD WITH CIGS VARYING FROM MVFR/VFR DURING THE DAY AND VSBYS/CIGS STAYING LOWER AT NIGHT. THIS SLOW MOVING UPPER SYSTEM IS EXPECTED TO STALL ACROSS THE REGION INTO EARLY NEXT WEEK KEEPING THE THREAT OF SHOWERS AND STORMS AROUND ALONG WITH POTENTIAL FOR MVFR OR WORSE CIGS/VSBYS. && .RNK WATCHES/WARNINGS/ADVISORIES...
