The episode as NWS LWX wrote it up.
A strong cold front pushed across the Mid Atlantic on the evening of June 8th. Ahead of the front, temperatures measured in the mid to upper 90s and dew points around 70, creating a heat index above 100. This warm and unstable airmass allowed scattered showers and thunderstorms to develop over northern and central Virginia during the afternoon and continued through the evening. Some of these storms became severe, producing large hail and damaging winds that downed trees and power lines.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC
301 PM EDT FRI JUN 8 2007
.SYNOPSIS...
A COLD FRONT WILL CROSS THE AREA LATE TONIGHT. HIGH PRESSURE WILL
BUILD BACK OVER THE REGION THROUGH THE MIDDLE OF NEXT WEEK.
&&
.NEAR TERM /THROUGH TONIGHT/...
ATMOS IS HOT AND VERY UNSTABLE WITH SURFACE-BASED CAPE OF AROUND
2500 J/KG AND LIFTED INDEX OF -5C. ISOLD STORMS ALREADY
DEVELOPING W OF THE BLUE RIDGE MTNS AND EXPECT THEM TO INCREASE IN
CVRG THRU THE AFTERNOON AND EARLY EVENING. ISOLD PULSE SVR IS THE
MAIN THREAT WITH THESE STORMS.
LINE OF STORMS EXTENDING FROM OH TO TN WILL MOVE INTO THE FAR WEST
AFTER 00Z. UNCERTAINTY REMAINS AS TO WHETHER THIS LINE CAN SUSTAIN
ITSELF AS IT CROSSES THE MTNS. MOST LIKELY SCENARIO IS FOR STORMS
TO HAVE DISSIPATED BY MIDNIGHT WITH LOSS OF HEATING AND UPPER LVL
SUPPORT PASSES TO THE NORTH.
&&
.SHORT TERM /SATURDAY/...
NICE DAY IN STORE WITH LOWERING HUMIDITIES AND CLEARING SKIES AS
HIGH PRES BUILDS. TEMPS STILL VERY WARM IN THE UPPER 80S BUT
NOTICEABLY DRIER AIR.
&&
.LONG TERM /SATURDAY NIGHT THROUGH FRIDAY/...
1018 HPA HIGH PRES CENTERED OVER THE GREAT LAKES SAT NIGHT WILL
REMAIN NEARLY STATIONARY ON SUNDAY...AND KEEP NORTHERLY WINDS OVER
THE AREA ON SUN. THE 12Z NAM GFS AND 09Z SREF SHOW ON SUN A WEAK UPR
LEVEL DISTURBANCE MOVING SW FROM THE GREAT LAKES AND BRUSHING OVER
THE NE PORTION OF THE CWA DURING SUN AFTERNOON. THE 12Z NAM ACTUALLY
HAD SOME PRECIP OVER THE CHES BAY ON SUN...BUT FEW OF THE SREF
ENSEMBLES HAVE MUCH MOISTURE.
MDLS IN BASIC AGREEMENT ON KEEPING OMEGA PATTERN OVER NORTH AMERICA
WITH TROUGHS ALONG BOTH COASTS AND THE RIDGE OVER THE CENTRAL
PORTION OF THE CONTINENT. MODEL TIMING OF THE BREAKDOWN OF THIS
PATTERN TOWARD THE END OF THE PERIOD STILL HAS SOME QUESTIONS. THE
12Z GFS BRINGS A UPPER LEVEL DISTURBANCE COMING OVER THE RIDGE AXIS
ON WED AND RACING DOWN THE EASTERN SEABOARD ON THUR BEFORE TAKING UP
A POSITION OVER LONG ISLAND ON FRI AND SAT. SOME CHANCES FOR PRECIP
FOR LATE IN THE PERIOD...WED-FRI...BUT WILL BE DEPENDENT ON DETAILS
OF UPPER LEVEL FEATURES THAT AT THIS POINT ARE STILL TOO UNCERTAIN
TO PIN DOWN. REGARDLESS...THE PATTERN LOOKS ALITTLE UNSETTLED TOWARD
THE END OF THE WEEK.
