The radar
The Roanoke radar (KFCX), 142 km from the middle of the area, began a volume at 22:04 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.
Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.
Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.
The nearest sounding before it
Roanoke, VA (KRNK), launched 12:00Z, 10.0 hours before the alert went out and 73 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

HTSWhat 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 Baltimore/Washington wrote its last area forecast discussion before this severe thunderstorm warning went out at May 22, 3:18 PM EDT, 2 hours 43 minutes earlier.
Area forecast discussion, May 22, 3:18 PM EDT, 2 hours 43 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC 318 PM EDT TUE MAY 22 2012 .SYNOPSIS... LOW PRESSURE WILL PERSIST OVER THE MID ATLANTIC THROUGH THURSDAY. HIGH PRESSURE IS THEN EXPECTED FOR THE SOUTHEASTERN AND MID ATLANTIC STATES THROUGH THE MEMORIAL DAY WEEKEND...BRINGING MUCH ABOVE NORMAL TEMPERATURES. && .NEAR TERM /THROUGH WEDNESDAY/... EXPECT THE UPTICK IN SHOWERS/THUNDERSTORMS TO CONTINUE ACROSS THE CWA THROUGH THE REST OF THE AFTERNOON. INITIALLY...THE WESTERN HALF OF THE CWA WILL BE MOST AFFECTED...BUT EXPECT ADDITIONAL DEVELOPMENT FURTHER EAST AS A CONVERGENT AXIS SHIFTS EVER-SO-SLIGHTLY/SLOWLY TO THE EAST THROUGH THE EVENING HOURS /AND CAPE INCREASES/. ONGOING ACTIVITY MAY EXHIBIT SLIGHT EASTWARD PROPAGATION AS WELL...DESPITE WEAK STEERING FLOW. THIS IS ALSO IMPLIED BY THE LAST SEVERAL RUNS OF THE HRRR. 12Z KIAD RAOB INDICATED THAT PRECIPITABLE WATERS HAVE COME DOWN OVER THE LAST 24 HOURS...1.20 INCHES. THIS IS LIKELY DUE TO SOME MID-LEVEL DRYING...BUT THE LOW LEVELS REMAIN MOIST. THIS COMBINED WITH SLOW MOVEMENT OF STORMS AND POSSIBLE WARM RAIN PROCESSES MEANS THAT CONVECTION WILL POSE A HEAVY RAINFALL THREAT THIS AFTERNOON AND EVENING...WHICH COULD LEAD TO ISOLATED FLASH FLOODING MAINLY NEAR THE HIGHLANDS AND LOCATIONS THAT RECEIVED HEAVY RAINFALL/FLASH FLOODING LAST NIGHT /SUCH AS PRINCE WILLIAM AND LOUDOUN COUNTIES IN VIRGINIA/. HIGHEST COVERAGE OF CONVECTION SHOULD OCCUR THROUGH MID EVENING...AND EXPECT CONVECTION TO BEGIN TO DIMINISH LATER THIS EVENING BUT WITH A TROUGH/LOW LEVEL BOUNDARY REMAINING OVER THE CWA WILL CONTINUE A LOW CHANCE OF SHOWERS AFTER MIDNIGHT ACROSS THE CWA. THERE MAY ALSO BE PATCHY FOG LATE. ON WEDNESDAY...EXPECT A NEAR REPEAT PERFORMANCE WITH A LINGERING TROUGH IN PLACE AND MOIST LOW LEVELS. INITIATION MAY BE SLIGHTLY EARLIER...BUT LIKE TODAY THE HIGHEST COVERAGE WILL FAVOR AFTERNOON AND EVENING /FOR LIKELY POPS/. AM WORRIED THERE MAY ALSO BE A MORE WIDESPREAD RISK FOR HEAVY RAINFALL/FLASH FLOODING AND A FLASH FLOOD WATCH COULD BECOME NECESSARY. FOR TEMPERATURES STAYED CLOSE TO MOS TONIGHT...AND THEN FAVORED THE COOLER MET MOS ON WEDNESDAY GIVEN EXPECTED CLOUDS AND SHOWERS. && .SHORT TERM /WEDNESDAY NIGHT THROUGH THURSDAY NIGHT/... THE UPPER LOW OVER THE MID ATLANTIC IS PROGGED TO FILL AND DRIFT NORTHEAST WED NIGHT THROUGH THUR NIGHT PER LATEST GFS/ECMWF GUIDANCE. REMNANT COOL AIR ALOFT WILL STILL BE SIGNIFICANT ENOUGH FOR DIURNALLY DRIVEN THUNDERSTORMS...DYING OUT WEDNESDAY EVENING...THEN FIRING AGAIN THURSDAY AFTERNOON. PWATS OF 1.2 TO 1.5 INCHES...SBCAPE 1500 TO 2000 J/KG...AND MINIMAL BULK SHEAR SUGGEST SLOW MOVING GARDEN VARIETY THUNDERSTORMS. ANY FLOODING CONCERN WILL DEPEND ON COVERAGE/INTENSITY OF WEDNESDAY ACTIVITY...BUT LOOKS TO BE QUITE ISOLATED AT BEST FOR THURSDAY. WITH SELY FLOW EXPECT TEMPERATURES ABOUT 10 DEGREES ABOVE NORMAL...MINS IN THE LOW TO MID 60S AND MAX TEMPS THURSDAY IN THE LOW TO MID 80S /DEPENDENT ON CLOUD AND PRECIP COVERAGE/. && .LONG TERM /FRIDAY THROUGH TUESDAY/... A RIDGE BUILDS FROM THE SERN US...EXPANDING INTO THE MID ATLANTIC /PER GFS/ECMWF GUIDANCE/ FRIDAY CONTINUING THROUGH MEMORIAL DAY. THIS WILL ENABLE A STRONG WARM AIR ADVECTION WITH NEAR RECORD TEMPERATURES INTO THE REGION BY SATURDAY. STAYED CLOSE TO HPC GUIDANCE WHICH CAME IN WARMER...MAX TEMPS LOW TO MID 90S SATURDAY THROUGH MONDAY. A TROUGH CROSSES THE GREAT LAKES/ST LAWRENCE VALLEY FRIDAY NIGHT AND SATURDAY WHICH SHOULD CAUSE ACTIVE WEATHER IN PA. GUIDANCE KEEPS THIS NORTH OF THE MASON-DIXON FOR NOW...AND THE STRENGTH OF THE RIDGE /590DAM AT 500MB/ SHOULD KEEP AT LEAST MOST OF THE LWX CWA ON THE WARM SIDE. DEWPOINTS CURRENTLY PROGGED TO BE MORE MID/UPR 60S WHICH WOULD PRODUCE HEAT INDICES ONLY A FEW DEGREES ABOVE THE MAX TEMP /THUS MID TO UPR 90S HEAT INDICES EXPECTED/. BOOSTED WORDING IN THE HWO FOR HEAT...PARTICULARLY CONSIDERING THE HOLIDAY WEEKEND. && .AVIATION /19Z TUESDAY THROUGH SUNDAY/... BACKED OFF ON CONVECTIVE POTENTIAL BY A COUPLE OF HOURS AT THE HUBS DURING THE 18Z TAF CYCLE. CHO/MRB WOULD BE AFFECTED FIRST...THEN ADDITIONAL DEVELOPMENT AND/OR SLOW EASTWARD PROPAGATION OF EXISTING ACTIVITY MAY AFFECT THE HUBS CLOSER TO 21Z THROUGH THE 00Z/01Z TIME FRAME. WITH LOW LEVEL MOISTURE REMAINING...EXPECT STRATUS AND PERHAPS ALSO FOG TO DEVELOP OVERNIGHT. PERIOD OF IFR IS EXPECTED INTO EARLY/MID MORNING WEDNESDAY BEFORE SCATTERED TO NUMEROUS THUNDERSTORMS WILL BE DEVELOPING AGAIN BY WEDNESDAY AFTERNOON. DIURNAL THUNDERSTORMS WEDNESDAY EVENING...THEN AGAIN THURSDAY/EVENING. ISOLATED IFR IN HEAVIEST RAINFALL. FOG POSSIBLE LATE NIGHTS SHOULD CLEARING OCCUR...PARTICULARLY AT AREAS WITH SIGNIFICANT RAINFALL. SELY FLOW THURSDAY INTO THE WEEKEND. HOT HIGH PRESSURE THIS WEEKEND WITH ISOLATED AFTERNOON THUNDERSTORMS AT MOST. && .MARINE... FAIRLY WEAK WIND REGIME IN PLACE OVER THE WATERS...WITH AN EAST/SOUTHEAST WIND GENERALLY 10 KT OR LESS THROUGH WEDNESDAY. THUNDERSTORMS MAY AFFECT THE WATERS THIS EVENING...AND THEN AGAIN WEDNESDAY AFTERNOON/EVENING. SELY FLOW 10 TO 15 KT WEDNESDAY NIGHT...INCREASING TO AROUND 20 KT THURSDAY...A SMALL CRAFT ADVISORY IS EXPECTED...PROBABLY LESS THEN FRIDAY /NO SCA EXPECTED/. FLOW BECOMES SWLY THEN THIS WEEKEND...WITH SUB SCA HEADLINE FLOW. && .TIDES/COASTAL FLOODING... HIGH TIDE THIS EVENING IS THE LOWER OF THE NEXT TWO...AND LOOKS TO REMAIN BELOW MINOR TIDAL FLOODING THRESHOLDS. HOWEVER WITH 1/2 TO 1 FOOT ANOMALIES...THE WEDNESDAY MORNING HIGH TIDE CYCLE WILL BE SUSCEPTIBLE TO MINOR FLOODING ESPECIALLY AT LOCATIONS SUCH AS ANNAPOLIS AND ALEXANDRIA. A COASTAL FLOOD ADVISORY MAY BECOME NECESSARY. A MINOR COASTAL FLOOD THREAT WILL CONTINUE INTO THIS WEEKEND AS SOUTHEASTERLY FLOW CONTINUES THROUGH FRIDAY...SLOWLY BECOMING SLY THROUGH THE WEEKEND. && .LWX WATCHES/WARNINGS/ADVISORIES...
