The episode as NWS LWX wrote it up.
A potent storm system crossed the region May 12th. Warm and moist air filtered in ahead of the system, bringing widespread showers and thunderstorms with heavy rain. Heavy rain began to overspread the region during the evening of the 11th and continued through the morning of the 12th. The pressure gradient with the low pressure system produced strong gusty winds across portions of northern and central Virginia during the late evening. With the ground already saturated dozens of trees and power lines fell across the region. Many roads remains closed into the afternoon of the 12th.
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 May 11, 2:01 PM EST, 3 hours 59 minutes earlier.
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC
301 PM EDT SUN MAY 11 2008
.SYNOPSIS...
A POTENT STORM SYSTEM WILL APPROACH FROM THE OHIO VALLEY THIS
EVENING...PASSING THROUGH OUR REGION OVERNIGHT. IT WILL SLOWLY
MOVE OFF THE MID-ATLANTIC COAST MONDAY. SIGNIFICANT RAINFALL IS
EXPECTED FROM THIS STORM SYSTEM WITH THE HEAVIEST RAIN EXPECTED
LATER THIS AFTERNOON THROUGH TONIGHT. HIGH PRESSURE WILL SLOWLY
BUILD IN BEHIND THIS STORM FOR TUESDAY AND WEDNESDAY. ANOTHER COLD
FRONT WILL APPROACH THROUGH THURSDAY...AND PROVIDE THE RISK OF
RAIN FOR THE END OF THE WEEK.
&&
.NEAR TERM /UNTIL 6 AM MONDAY MORNING/...
WATER VAPOR LOOP SHOWS A VIGOROUS UPPER LOW TRANSLATING EAST OVER
THE MIDWEST. A DRY SLOT IS INTRUDING OVER THE TENNESSEE VALLEY.
ACARS 400-250MB WIND OBSERVATIONS SHOW A 110-150KT CYCLICALLY CURVED
JET FROM THE PLAINS INTO THE CENTRAL APPALACHIANS. 11Z SURFACE
ANALYSIS PLACED A 985MB OCCLUDED CYCLONE IN EAST CENTRAL ILLINOIS.
THE OCCLUDED BOUNDARY EXTENDED SOUTHEAST INTO NORTHERN
ALABAMA...WITH A COLD FRONT CONTINUING SOUTHWEST ACROSS SOUTHERN
TEXAS. A WARM/STATIONARY BOUNDARY STRETCHED EAST FROM CENTRAL
ALABAMA THROUGH SOUTHERN GEORGIA. RIDGING IS OCCURRING EAST OF THE
APPALACHIANS WITH A COASTAL BOUNDARY BEGINNING TO DEVELOP ALONG THE
EASTERN CAROLINAS. A PRE-FRONTAL TROUGH WAS NOTED 50-100 MILES AHEAD
OF THE OCCLUDED BOUNDARY.
CONVECTIVE LINE AHEAD OF UPPER LOW CURRENTLY APPROACHING THE
APPALACHIANS. 09Z SREF INDICATE GREATER ELEVATED INSTABILITY ALOFT
THIS EVENING THAN THE 03Z RUN...AND GIVEN CURRENT CG ACTIVITY...HAVE
ADDED THUNDER TO THE FORECAST. THE GREATEST FLASH FLOOD RISK IS LATE
THIS AFTERNOON THROUGH THE LATE EVENING AS CONVECTIVE ACTIVITY
STRATIFIES ACROSS THE REGION. AS THE UPPER LOW PASSES OVERHEAD
OVERNIGHT...EXPECT PRECIPITATION TO PIVOT WESTWARD (NORTH OF THE
UPPER LOW)...FOCUSING ACROSS THE NORTHERN ZONES. THIS WOULD
POTENTIALLY LEAD TO A MORE PROLONGED FLOOD THREAT.
SOUTHERN EDGE OF AFOREMENTIONED CONVECTIVE LINE HAS MADE A RUN TO
THE SOUTHEAST ACROSS SOUTHERN VIRGINIA TOWARD GREATER BOUNDARY LAYER
INSTABILITY. AT THIS TIME DO NOT EXPECT NORTHWARD EXPANSION OF
SEVERE WEATHER THREAT GIVEN THE TRACK OF THE TRIPLE POINT LOW.

STRONG WNDS RETURN TMRW AS DEFORMATION AXIS SWINGS THRU AND FLOW
