The episode as NWS LWX wrote it up.
An isolated flooding incident occurred in Fairfax County due to locally heavy rain.
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 Jun 27, 2:10 PM EST, 3 hours 5 minutes earlier.
Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 310 PM EDT Thu Jun 27 2019 .SYNOPSIS... High pressure will remain overhead through Friday before moving offshore Saturday. A cold front will pass through Sunday into Sunday evening before high pressure returns for Monday. High pressure will move offshore for the middle portion of next week. && .NEAR TERM /THROUGH TONIGHT/... Surface high pressure remains atop the forecast area this afternoon. However, a subtle mid level impulse has assisted terrain circulations, acting upon modest instability (MLCAPE near 1000 j/kg) to produce widely scattered thunderstorms across western and central portions of the area...not just confined to the ridge tops. CAMs have primarily captured the midday activity, with a suggestion there may be a secondary uptick late this afternoon-early this evening. Based upon satellite and radar trends, that may be initiating at this time. Even though MLCAPE not excessively high, low-level lapse rates are sizeable (8-9C/km)...which is to be expected with temperatures near 90F. Consequently, storms have the potential to bust through a fairly dry atmosphere (in a deep-layer sense) without shear. Any mature storms, while sparse, have the potential to produce severe hail or damaging winds...as has already happened in the southeastern corner of Augusta County. This local severe weather risk has been added to the Hazardous Weather Outlook. Activity should dissipate by sunset or soon thereafter as forcing and heating are both lost. Dewpoints will increase by a degree or two, making for a slightly muggier night and increasing the potential for patchy fog. Will emphasize the river valleys. Low in the 60s, except 70-75 downtown DC/Baltimore. && .SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/... The ridge axis will slide offshore Friday into Saturday, which will increase surface-850 mb temperatures as well as humidity. Precipitation Friday does not look as organized as it did in yesterday's guidance runs. However, believe that instability may be a pinch higher than today. It would need to be to overcome possible warm advection. Consequently will not adjust PoPs; forecasting scattered late-day coverage Blue Ridge west. Heights lower Saturday as a cold front drops south across Pennsylvania. While that may aide thunderstorm development, the westerly flow may negate it. The compressional warming may make this the warmest day of the stretch, but heat index values should still remain below criteria. Forecast still carries a 20-30 percent chance in the afternoon, with storms potentially dropping south through the evening. Highs will be in the lower- mid 90s. && .LONG TERM /SUNDAY THROUGH THURSDAY/... A frontal boundary will be in the vicinity of our region on Sunday. There remains some uncertainty on the timing of the backdoor front moving through our region. The models range from the front moving through on Saturday too it moving through on Sunday. The main effect of this difference is whether showers and thunderstorms will be possible on Sunday. Behind the frontal passage, temperatures should drop as winds become more northwesterly leading to cooler and drier air being transported into our region. Weak high pressure will build into our region through Tuesday morning. Another backdoor front is forecast to approach from our north sometime late Tuesday into Wednesday. At this time there remains a lot of uncertainty on the timing and how widespread showers and thunderstorms will be as this front moves through our region. Temperatures will trend back up into the upper 80s to low 90s by the middle of next week. && .AVIATION /18Z THURSDAY THROUGH TUESDAY/... There is a possibility for a stray shower/thunderstorm affecting the CHO/MRB this afternoon/early evening, producing brief flight restrictions. Threat too limited to include in TAFs; will address via amendments...as was done with CHO earlier this afternoon. The increased humidity will make patchy early morning fog more likely. Will be carrying MVFR at CHO/MRB early Friday, and it'll be possible again early Saturday. Local/brief thunderstorms may once again be a factor Friday-Saturday afternoon/early evening as well. Periods of mid to high level clouds will be possible on Sunday as showers and thunderstorms are potential. Brief periods of subVFR conditions are possible. Mostly clear skies expected on Monday with light winds out of the northwest. VFR conditions expected at this time. && .MARINE... Winds on the water will be light tonight through Friday night. Onshore flow will dominate in this regime this afternoon and tonight. Flow will become more south/southwest Friday, although onshore flow may once again prevail late in the day. By Saturday, westerlies will increase but do not believe that we'll reach Small Craft thresholds. Showers and storm will be potential over the waters on Sunday with winds generally out of the west to northwest. Winds could gust over 18 knots leading to the need for Small Craft Advisories Winds will become light out of the northwest on Monday. Small Craft Advisories may be need early on Monday. && .LWX WATCHES/WARNINGS/ADVISORIES... DC...None. MD...None. VA...None. WV...None. MARINE...None. && SYNOPSIS...
