An upper-level disturbance triggered a few showers and thunderstorms. There was enough instability from a hot and humid air mass for a few thunderstorms to produce damaging wind gusts and large hail across the western portion of the state.

The episode as NWS LWX wrote it up.
An upper-level disturbance triggered a few showers and thunderstorms. There was enough instability from a hot and humid air mass for a few thunderstorms to produce damaging wind gusts and large hail across the western portion of the state.
The local office's own words before the first event, 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 the first event at Jul 3, 1:45 PM EST, 3 hours 28 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC 245 PM EDT TUE JUL 3 2012 .SYNOPSIS... A FRONTAL BOUNDARY ACROSS CENTRAL VIRGINIA WILL SLOWLY MOVE NORTHWARD THROUGH THE AREA. AN UPPER LEVEL DISTURBANCE WILL TRACK NORTH OF THE AREA WEDNESDAY. HIGH PRESSURE WILL RETURN FOR THE LATTER PART OF THE WEEK. && .NEAR TERM /THROUGH WEDNESDAY/... WARM FRONT WAS LIFTING NORTH TOWARD THE MASON DIXON LINE THIS AFTERNOON. DEWPOINTS ARE STILL RELATIVELY LOW ACROSS THE CWA...BUT AS LOW LEVEL WINDS SHIFT TO THE SOUTH EXPECT DEWPOINTS AND PRECIPITABLE WATER VALUES TO CREEP UP THROUGH THE EVENING. GIVEN INITIAL DRY AIR AND SOME WARMING GOING ON ALOFT...EXPECT CONVECTION TO HOLD OFF THROUGH AT LEAST MID-AFTERNOON. AT 17Z...ISOLATED STORMS WERE BEGINNING TO DEVELOP OVER THE SOUTHERN APPALACHIANS...AND A COMPLEX OF THUNDERSTORMS THAT WAS OVER NORTHEAST OHIO THIS MORNING WAS MOVING INTO NORTHWEST PENNSYLVANIA. LATER THIS AFTERNOON...SIMILAR TO WHAT IS OCCURRING ACROSS THE SOUTHERN APPALACHIANS...ISOLATED STORMS MAY POP UP OVER THE HIGHER TERRAIN. HOWEVER...EXPECT MUCH OF THE REST OF THE CWA TO REMAIN DRY WITH PARTLY SUNNY SKIES DUE TO CIRRUS FROM MCS DEBRIS. IF THAT MCS HOLDS TOGETHER...THEN IT LIKELY WILL BRING AT LEAST SCATTERED THUNDERSTORMS ACROSS THE CWA THIS EVENING. EVEN IF IT WEAKENS...ADDITIONAL STORMS MAY RE-FIRE ALONG ITS BOUNDARY AS MOISTURE INCREASES THIS EVENING. THIS IS DEPICTED BY THE HRRR. THERE OBVIOUSLY REMAINS SOME UNCERTAINTY WITH THE EVOLUTION OF THIS PARTICULAR SYSTEM...SO HAVE KEPT POPS IN THE CHANCE CATEGORY THIS EVENING. IN ADDITION...SOME MODEL GUIDANCE INCLUDING THE NAM...GFS AND LWX WRF-ARW INDICATES THAT A CLUSTER OF THUNDERSTORMS...POSSIBLY AN MCS...MAY APPROACH OR MOVE INTO THE CWA OVERNIGHT. THIS MAY BE SOMEWHAT AFFECTED BY WHAT OCCURS EARLIER THIS EVENING...AND THUS THERE ARE INHERENT UNCERTAINTIES. WILL CONTINUE CHANCE POPS OVERNIGHT. ON WEDNESDAY...ATMOSPHERE WILL BE MOIST AND UNSTABLE. CAN/T RULE OUT SOME ONGOING CONVECTION AT THE START OF THE DAY...BUT MOST GUIDANCE SUGGEST THE CWA WOULD BE DRY DURING THE LATE MORNING/EARLY AFTERNOON BEFORE SCATTERED THUNDERSTORMS DEVELOP. LEE TROUGH AND MID-LEVEL SHORTWAVE APPEAR TO BE SUFFICIENT TRIGGERS. SOME OF THE STORMS MAY BE SEVERE WITH LARGE HAIL AND DAMAGING WIND GUSTS. CLOUDS WILL HAVE AN IMPACT ON HOW WARM IT GETS ON WEDNESDAY. CURRENT FORECAST IS FOR MID 90S...AND WITH HIGHER HUMIDITY THAN TODAY IT WILL FEEL EVEN HOTTER. EAST OF THE BLUE RIDGE...HEAT INDEX VALUES ARE FORECAST TO BE AROUND 100 DEGREES. && .SHORT TERM /WEDNESDAY NIGHT/... AN UPPER-LEVEL DISTURBANCE WILL PASS THROUGH IN THE NORTHWEST FLOW ALOFT. WARM AND HUMID CONDITIONS WILL PERSIST DURING THIS TIME. HIGH AMOUNTS OF INSTABILITY ALONG WITH FORCING FROM THE UPPER-LEVEL DISTURBANCE WILL CAUSE A CHANCE FOR SHOWERS AND THUNDERSTORMS...MAINLY DURING THE EVENING. ANY T-STORMS THAT DO DEVELOP WILL HAVE THE POTENTIAL TO PRODUCE DAMAGING WIND GUSTS DUE TO HIGH AMOUNTS OF INSTABILITY. THE HEAT AND HUMIDITY WILL ALSO BE A THREAT FOR PEOPLE VENTURING OUTDOORS WEDNESDAY EVENING. HEAT INDICES WILL BE IN THE 80S AND 90S ACROSS MOST AREAS DURING THIS TIME. && .LONG TERM /THURSDAY THROUGH TUESDAY/... UPPER-LEVEL HIGH PRESSURE OVER THE MIDWEST WILL EXTEND EAST TOWARD THE MID-ATLANTIC THURSDAY AND FRIDAY. SUBSIDENCE ASSOCIATED WITH THIS SYSTEM WILL PRODUCE UNUSUALLY HOT CONDITIONS. HUMIDITY WILL ALSO REMAIN HIGH AS THE LOW-LEVEL FLOW CONTINUES TO CIRCULATE AROUND HIGH PRESSURE THAT EXTENDS FROM THE ATLANTIC OCEAN INTO THE SOUTHERN CONUS. HEAT INDICES NEAR OR ABOVE 100 DEGREES ARE EXPECTED ACROSS MANY LOCATIONS THURSDAY AND FRIDAY. A HEAT ADVISORY MAY BE NEEDED FOR PORTIONS OF THE AREA DURING THIS TIME. MOST LOCATIONS WILL REMAIN DRY SINCE SUBSIDENCE FROM THE UPPER-LEVEL HIGH WILL PROVIDE A STRONG CAPPING INVERSION. THE ONE EXCEPTION MAY BE ACROSS THE CENTRAL SHENANDOAH VALLEY INTO THE POTOMAC HIGHLANDS THURSDAY AFTERNOON WHERE AN ISOLATED T-STORM CANNOT BE RULED OUT. THE UPPER-LEVEL RIDGE WILL FLATTEN OUT A BIT SATURDAY AS SHORTWAVE ENERGY PASSES BY TO THE NORTH. THIS WILL ALLOW FOR A BOUNDARY TO APPROACH THE AREA SATURDAY NIGHT INTO SUNDAY. HOT AND HUMID CONDITIONS WILL PERSIST THROUGH THE WEEKEND...BUT THE BOUNDARY WILL BRING AN INCREASING CHANCE FOR SHOWERS AND T-STORMS. THE BOUNDARY MAY STALL OUT NEAR THE REGION DURING THE EARLY PORTION OF NEXT WEEK...CAUSING UNSETTLED CONDITIONS. && .AVIATION /19Z TUESDAY THROUGH SUNDAY/... MAIN CHALLENGE REVOLVES AROUND THUNDERSTORM POTENTIAL THROUGH WEDNESDAY. THERE REMAINS UNCERTAINTY REGARDING EVOLUTION OF THUNDERSTORM CLUSTERS AND ASSOCIATED TIMING. FOLLOWING RECENT HRRR RUNS...HAVE INSERTED VCTS/CB ACROSS MOST TAF SITES THIS EVENING AS UPSTREAM MCS MOVES SOUTHEAST WITH TIME...POSSIBLY BUILDING SOUTHWARD. SOME GUIDANCE REVEALS THAT ADDITIONAL THUNDERSTORMS MAY BE POSSIBLE LATE TONIGHT...BUT LOW CONFIDENCE PRECLUDED INCLUSION IN 18Z TAFS. LEE TROUGH AND MID-LEVEL SHORTWAVE WILL BRING A CHANCE OF THUNDERSTORMS BY WEDNESDAY AFTERNOON. VFR CONDITIONS ARE EXPECTED MOST OF THE TIME WEDNESDAY NIGHT THROUGH SUNDAY. SCATTERED T-STORMS ARE POSSIBLE WEDNESDAY EVENING AND T-STORMS WILL BE CAPABLE OF PRODUCING GUSTY WINDS AND HAIL. DRY CONDITIONS ARE EXPECTED THURSDAY AND FRIDAY ACROSS MOST OF THE TERMINALS. AN APPROACHING BOUNDARY WILL BRING INCREASING CHANCES FOR SHOWERS AND THUNDERSTORMS DURING THE WEEKEND. && .MARINE... REST OF THE AFTERNOON SHOULD BE DRY ACROSS THE WATERS...BUT WILL HAVE TO WATCH FOR THE POTENTIAL OF SCATTERED THUNDERSTORMS THIS EVENING WHICH COULD PRODUCE GUSTY WINDS. A CHANCE OF THUNDERSTORMS WILL CONTINUE INTO WEDNESDAY...PARTICULARLY IN THE AFTERNOON AND EVENING. WINDS ARE EXPECTED TO REMAIN BELOW SCA CRITERIA FOR MOST OF THE EXTENDED PERIOD. SCATTERED T-STORMS WEDNESDAY EVENING WILL BE CAPABLE OF PRODUCING GUSTY WINDS AND HAIL. A BOUNDARY WILL APPROACH THE WATERS DURING THE WEEKEND...BRINGING AN INCREASING CHANCE FOR SHOWERS AND T-STORMS. && .LWX WATCHES/WARNINGS/ADVISORIES... DC...NONE. MD...NONE. VA...NONE. WV...NONE.
