The episode as NWS LWX wrote it up.
A weak cold front moved through the region and stalled over the area. Convergence along the boundary led to heavy showers. A few breaks in the clouds led to an increase in instability and thunderstorms that produced heavy rain in activity.

AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC 248 PM EDT MON JUN 17 2013 .SYNOPSIS... A WEAK COLD FRONT APPROACHING FROM THE NORTH WILL STALL OVER THE MID ATLANTIC THROUGH TUESDAY...THEN MOVE SOUTH OF THE REGION EARLY WEDNESDAY. AN AREA OF LOW PRESSURE WILL TRACK SOUTH OF THE AREA TUESDAY NIGHT. HIGH PRESSURE WILL RETURN FOR THE REMAINDER OF THE WEEK. && .NEAR TERM /THROUGH TUESDAY/... COLD FRONT REMAINS LOCATED OVER THE LOWER GREAT LAKES THIS AFTERNOON...HOWEVER A SURFACE TROUGH AND OTHER SMALLER MESOSCALE BOUNDARIES WERE OBSERVED OVER THE CWA. SCATTERED SHOWERS AND THUNDERSTORMS WERE INITIATING ALONG/NEAR THESE BOUNDARIES EARLY THIS AFTERNOON. PER MOST GUIDANCE...BELIEVE THE BULK OF THE ACTIVITY WILL BE LOCATED FROM NORTHEAST MARYLAND SOUTHWARD THROUGH CENTRAL AND SOUTHERN MARYLAND AND INTO CENTRAL VIRGINIA. THIS IS WHERE CHANCE POPS FOR SCATTERED CONVECTION WILL RESIDE DURING THE AFTERNOON...WITH ONLY ISOLATED ACTIVITY FURTHER TO THE NORTHWEST. DESPITE THE PRESENCE OF SURFACE BOUNDARIES...LARGER SCALE FORCING IS FAIRLY WEAK AND INSTABILITY APPEARS TO BE ON THE WEAK SIDE TOO WITH MODIFIED 12Z SOUNDING REVEALING ONLY ABOUT 1000 J/KG. SPC MESOANALYSIS PAGE INDICATES A LITTLE MORE THAN THAT BUT AM NOT EXPECTING WIDESPREAD SEVERE ACROSS THE CWA. PERHAPS A COUPLE CELLS WIND UP PULSING UP AND BECOMING STRONG ENOUGH TO PRODUCE LOCALLY GUSTY WINDS DURING THE AFTERNOON. MOST ACTIVITY SHOULD WEAKEN/DIMINISH IN THE EVENING...WITH ANY LINGERING ACTIVITY LIKELY ACROSS THE EXTREME SOUTHERN PORTION OF THE CWA. COLD FRONT WILL ALSO START TO SINK SOUTHWARD INTO PENNSYLVANIA TONIGHT BUT IT LOOKS LIKE ACTIVITY NEAR THAT BOUNDARY WILL REMAIN TO THE NORTH TONIGHT. BOUNDARY LOOKS TO RESIDE OVER THE CWA ON TUESDAY. CLOUDS AROUND THE BOUNDARY MAY HINDER DESTABILIZATION SOME...BUT MODELS SUGGEST 1-2K J/KG OF CAPE AND WITH THE BOUNDARY OVERHEAD EXPECT SCATTERED THUNDERSTORMS. IF SHEAR WINDS UP BEING A LITTLE BETTER...THEN A FEW STORMS COULD PRODUCE LOCALLY DAMAGING WIND GUSTS. && .SHORT TERM /TUESDAY NIGHT THROUGH WEDNESDAY/... BOUNDARY IS FORECAST TO STALL OUT JUST SOUTH OF THE CWA TUESDAY NIGHT/WEDNESDAY. BOTH NAM/GFS INDICATE A WAVE OF LOW PRESSURE RIDING ALONG THE FRONT...SPILLING SOME SHOWERS TO THE NORTH INTO THE CWA. BUT THE MODELS DISAGREE WITH TIMING...WITH THE GFS BEING FASTER AND FAVORING A MOSTLY DRY WEDNESDAY WHILE THE NAM INDICATES SHOWERS. GIVEN TIMING UNCERTAINTY...AND BLENDING THE ECMWF IN THE MIX HAVE FOCUSED HIGHEST POPS ACROSS THE CWA TUESDAY NIGHT BUT CONTINUE CHANCE POPS INTO THE FIRST PART OF WEDNESDAY. WILL HAVE TO FINE TUNE TIMING AS WE GET CLOSER. && .LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/... HIGH PRESSURE BUILDS IN TO END THE WEEK...THEN MOVES OFFSHORE OVER THE WEEKEND. EXPECT DRY CONDITIONS MUCH OF THE TIME HOWEVER ISOLATED DIURNAL THUNDERSTORMS MAY BE POSSIBLE OVER THE HIGHER TERRAIN FRIDAY INTO THE WEEKEND. THERE MAY ALSO BE A SHORTWAVE SOMETIME LATE SUNDAY INTO MONDAY WHICH COULD BRING A CHANCE OF THUNDERSTORMS TO THE ENTIRE CWA. NEAR NORMAL TEMPERATURES AT THE END OF THE WEEK COULD MODERATE A LITTLE ABOVE CLIMO OVER THE WEEKEND INTO THE FIRST PART OF NEXT WEEK. && .AVIATION /18Z MONDAY THROUGH SATURDAY/... WILL HAVE SCATTERED THUNDERSTORMS DEVELOPING DURING PEAK HEATING ALONG A TROUGH THIS AFTERNOON. BUT GIVEN LOW CONFIDENCE IN DIRECT IMPACT AT INDIVIDUAL SITES HAVE FOCUSED ON VCTS IN TAFS ATTM. IF BASED ON RADAR IT APPEARS ANY TERMINAL WILL HAVE MORE DIRECT IMPACT...AMENDMENTS WILL BE ISSUED. COLD FRONT SAGS SOUTHWARD TONIGHT INTO TUESDAY. EXPECT MORE SCATTERED CONVECTION TUESDAY AND PERHAPS EVEN INTO WEDNESDAY UNTIL HIGH PRESSURE PUSHES THE FRONT FAR ENOUGH SOUTH FOR DRY WX. && .MARINE... NO SCA FLAGS EXPECTED IN THE NEXT 24 HOURS WITH RELATIVELY WEAK GRADIENT. WILL HAVE TO WATCH LOCALLY GUSTY WINDS IN THUNDERSTORMS THIS AFTERNOON AND AGAIN TUESDAY. COLD FRONT MAKES IT WAY SOUTHWARD ACROSS THE WATERS ON TUESDAY...WITH A WAVE OF LOW PRESSURE RIDING ALONG THE FRONT TUESDAY NIGHT OR WEDNESDAY. HIGH PRESSURE BUILDS FOR THE END OF THE WEEK. && .LWX WATCHES/WARNINGS/ADVISORIES... DC...NONE. MD...NONE. VA...NONE. WV...NONE. MARINE...NONE. && BPP
