The episode as NWS LWX wrote it up.
The passage of a cold front and upper-level trough helped to trigger thunderstorms across northeastern Maryland on the third. Strong winds above the surface combined with high humidity at mid-levels caused damaging winds to mix down to the surface.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC
324 PM EDT SUN JUN 3 2012
.SYNOPSIS...
AN UPPER TROUGH WILL DRIFT EAST FROM THE GREAT LAKES TO NEW
ENGLAND THROUGH MONDAY...THEN PERSIST THROUGH WEDNESDAY NIGHT.
SEVERAL SHORTWAVES WILL ROTATE AROUND THE TROUGH...BRINGING
CHANCES OF SHOWERS AND BELOW NORMAL TEMPERATURES TO THE MID-
ATLANTIC STATES DURING THIS TIME. HIGH PRESSURE IS FORECAST TO
BUILD IN LATE IN THE WEEK AND OVER THE WEEKEND.
&&
.NEAR TERM /THROUGH MONDAY/...
AS OF 19Z...OCCLUDED LOW CENTERED OVER GEORGIAN BAY ONTARIO PER
WATER VAPOR IMAGERY. THE TROUGH OFF OF THIS LOW EXTENDS SOUTHEAST
ACROSS NEW ENGLAND AND INTO THE NORTH ATLANTIC.
SHORTWAVE ENERGY ROUNDING THIS TROUGH IS CURRENTLY MOVING THROUGH
PA...WITH A LINE OF SCATTERED THUNDERSTORMS IN ADVANCE ACROSS NEW
JERSEY. SOUTH OF THERE ACROSS LWX IS A GOOD CU FIELD WITH 700-1000
J/KG SBCAPE WITH NEAR NIL CIN. SCATTERED SHOWERS ARE DEVELOPING IN
THE WLY FLOW GUSTING TO AROUND 20 MPH. EXPECT AT LEAST ISOLATED
THUNDERSTORMS ACROSS MOST OF THE AREA BY THE LATE AFTERNOON. THE
BOUNDARY LAYER IS FAIRLY DRY...SO GUSTY DOWNDRAFTS/BURSTS ARE THE
MAIN THREAT. OTHERWISE THESE WILL BE PICTURESQUE HIGH-BASED CELLS.
EXPECT RAINFALL TO BE LESS THAN A QUARTER OF AN INCH.
TONIGHT...CONVECTIVE ACTIVITY CONTINUES THROUGH THE EVENING AND
POSSIBLY WELL INTO TONIGHT DEPENDING ON SHORTWAVE ACTIVITY AROUND
THE TROUGH. ONCE DIURNAL HEATING IS LOST THE COVERAGE AND INTENSITY
OF THUNDERSTORMS WILL DECREASE. MIN TEMPS MID 50S INLAND...UPR 50S
TO LOW 60S IN THE URBAN/NEAR SHORE ENVIRONS.
MONDAY...THE OCCLUDED LOW OVER THE ERN GREAT LAKES FILLS AS IT
DRIFTS EAST. MORE SHORTWAVE ENERGY IS EXPECTED TO PUSH SOUTH ACROSS
THE CENTRAL MID ATLANTIC. THE FORECAST IS DIURNALLY BASED
AGAIN...BUT PVA FROM AHEAD OF A SHORTWAVE COULD WARRANT AN EARLIER
ONSET. LOW LEVEL COLD AIR ADVECTION AND GREATER MORNING CLOUD COVER
WILL LIMIT TEMPERATURES A FEW DEGREES FROM TODAY. EXPECT MAX TEMPS
IN THE MID 70S...LOWER 70S UP ALONG THE MASON-DIXON...PERHAPS 80F
DOWN BY CHARLOTTESVILLE.
&&
.SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY NIGHT/...

CALMER CONDS OVNGT.
THE PTTN WON/T CHG MUCH FOR TUE-WED. CUTOFF H5 LOW OVER THE CNDN
MARITIMES WL HV SPOKES OF ENERGY ROTATING THRU CWFA...ANY OF WHICH
CAN INVIGORATE PCPN. BHD EACH SURGE...A BUBBLE OF COOLER MID LVL
TEMPS WL STEEPEN LAPSE RATES. SO WHILE MOST OF THE PCPN WL BE
DIURNALLY DRIVEN...THAT WON/T BE THE WHOLE STORY. CNVCTV INDICIES
NOT THAT IMPRESSIVE...SUGGESTING WL HV MORE OF A SHRA VS TSRA
THREAT...BUT WUD XPCT INVERTED V SNDGS SUGGESTING GUSTY WNDS AND
SMALL HAIL NONETHELESS. S/WV TROF AXIS A LTL MORE DEFINED WED...AND
WL INCL SCHC TSRA THEN.
PRETTY GOOD TEMP CONSISTENCY AMONGST MOS OFFERINGS-- MIN-T IN/NEAR
THE 50S...AND MAXT UPR 60S-LWR 70S.

.LONG TERM /THURSDAY THROUGH SUNDAY/...
WL HV A GRDL PTTN CHG END OF WK INTO THE WKND...AS THE TROF AXIS
PUSHES INTO ATLC AND THE L/WV RDG BLDS. SCT DIURNAL SHRA MAY HOLD ON
FOR ONE MORE DAY THU. AFTER THAT THERE SHUD BE ENUF SUBSIDENCE FOR
DRY WX...ALTHO CU MAY BUBBLE UP AGN FRI. AS HGTS RISE...LOOKING FOR
TEMPS TO WARM AS WELL. DEWPT RECOVERY WL BE A LTL SLOER. BY THE
WKND...TEMPS ABV CLIMO W/ MOSUN SKIES.

.AVIATION /20Z SUNDAY THROUGH FRIDAY/...
SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS ARE EXPECTED LATE THIS
AFTERNOON THROUGH THE EVENING WITH WESTERLY WINDS GUSTING UP TO 20

SHOWERS AND SLIGHTLY POSSIBLE THUNDERSTORMS MONDAY AS A LOW MOVES
EAST TO NEW ENGLAND. ONSET TIMING SHOULD BE EARLIER THAN TODAY. NWLY
FLOW GUSTING 20 TO 25 KT STARTING MID MORNING.
ISOL-SCT SHRA TUE-WED...EACH POSING A GUSTY WIND AND SMALL HAIL
THREAT. HWVR...AREAL CVRG MAY PRECLUDE IMPACT AT AIRFIELDS.

STARTING AT 6AM. SHOWERS WILL AGAIN HAVE THE POTENTIAL MIX DOWN
HIGHER GUSTS. GIVEN WIND FIELD IN THE LLVLS...SMWS MAY BE NEEDED OR
AN UPGRADE TO A GALE WRNG IF COVERAGE OF SHOWERS BECOMES HIGH ENOUGH.
