The episode as NWS LWX wrote it up.
A wave of low pressure moved across the Mid-Atlantic region along a frontal boundary. Warm and moist air moved into the region while strong winds aloft led to thunderstorm development. Heavy rain led to flooding across the Mid-Atlantic region.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC
1031 AM EST WED FEB 3 2016
.SYNOPSIS...
A COLD FRONT WILL APPROACH THE AREA TODAY BEFORE PASSING THROUGH
TONIGHT. A WAVE OF LOW PRESSURE DEVELOPS ALONG THE BOUNDARY
THURSDAY BEFORE PASSING BY WELL TO OUR EAST THURSDAY NIGHT INTO
FRIDAY. HIGH PRESSURE WILL RETURN FOR FRIDAY AFTERNOON INTO
SATURDAY. COASTAL LOW PRESSURE WILL PASS BY WELL TO OUR SOUTH AND
EAST SUNDAY. ANOTHER LOW PRESSURE SYSTEM MAY IMPACT THE AREA EARLY
NEXT WEEK.
&&
.NEAR TERM /THROUGH TONIGHT/...
LIGHT RAIN OCCURRING ALONG AND WEST I-95 CORRIDOR THIS MORNING.
SFC ANALYSIS SHOWING WARM FRONT EXTENDING SOUTH OVER EASTERN
WV...AND SPREADING WELL SOUTH OF THE AREA WITH THE COLD FRONT
STILL BACK OVER THE OH RIVER VALLEY. WEAK WIND FLOW HAS KEPT THE
WARM FRONTAL PASSAGE...AND LATEST THINKING IS IT WILL OCCUR THIS
AFTN WITH THE LLJ FINALLY NUDGING EAST. WITH THE LACK OF THE
FRONTAL PASSAGE...TEMPS HAVE BEEN SLOW TO WARM. HAVE BACKED OFF
ON HIGHS A FEW DEGREES...ESP OVER NORTHERN PORTIONS OF THE CWA.
HAZARD CONCERNS...FLOODING...GUSTY WINDS...AND THUNDERSTORMS.
SPARSE OBS AROUND THE POTOMAC HIGHLANDS SHOWING THAT WHILE WINDS
ARE GUSTING...NOT REACHING ADVISORY LVLS ANY MORE AS THE LLJ IS
PUSHING EAST. ALLOWED THE WIND ADVISORY TO EXPIRE AT 10 AM TO
REFLECT THIS CURRENT TREND. NOW CONCERNING WINDS FOR THIS
AFTN...GENERALLY SEEING A STABLE AIRMASS IN PLACE...RESTRICTING
MUCH INCREASE IN WINDS. BETTER CHC FOR GUSTING WINDS EASTERN HALF
OF THE CWA WHERE MEAGER INSTABILITY WILL BE PSBL LATER IN THE DAY
IN THE WAKE OF THE WARM FRONT. HOWEVER...ANY HEAVIER RAIN SHOWER
OR TSTM WILL BE CAPABLE OF MIXING DOWN THE STRONGER WINDS
ALOFT...AND AS SUCH...BETWEEN 19-02Z COULD SEE BRIEF GUSTS
BETWEEN 30-40 KTS.
FLOOD WATCH REMAINS IN EFFECT FOR THE NORTHERN HALF OF THE CWA TO
ACCOUNT FOR A COUPLE OF ISSUES...URBAN/SMALL STREAM FLOODING WITH
THE HEAVIER RAIN COUPLED WITH SNOWMELT AROUND THE DC/BALT METRO
AREAS...AND RIVER FLOODING BACK OVER CENTRAL MD/EASTERN WV
PANHANDLE. PLEASE REFER TO THE HYDRO SECTION FOR MORE DETAILS.
LASTING...FOR PCPN TIMING AND TSTM THREAT...LIGHT RAIN CONTINUING
THRU MIDDAY...WITH THE HEAVIER RAIN EXPECTED THIS AFTN. LACK OF
UPPER LVL FORCING SUGGESTING THEN THE BEST CHC FOR THE HEAVIER
RAIN COMES WITH THE COLD FRONT PASSAGE LATER TODAY. A WEAK VORT
MAX PASSING THIS EVENING COULD ENHANCE THE PCPN OVER SOUTHERN MD.
MORNING HI-RES MODELS SHOWING A LINE ORGANIZING RIGHT ALONG THE
FRONT LATE AFTN/EVENING TIME PERIOD WITH THE PCPN TAPERING OFF
QUICKLY IN THE WAKE. AS FOR SVR...WEAK FORCING...WEAK LAPSE
RATES...LACK OF SFC BASED CAPE SUGGEST NO SVR THREAT...HOWEVER
WILL MAINTAIN TSTM MENTION BASED UPON NEGATIVE SHOWALTER INDICES
GENERALLY DC METRO AND SOUTH THRU THIS EVENING. AS PREVIOUSLY
MENTIONED...ANY HEAVIER SHOWER/TSTM COULD BRING DOWN GUSTY WINDS.
&&
.SHORT TERM /TONIGHT THROUGH FRIDAY NIGHT/...
HEAVIEST AND MOST WIDESPREAD RAIN SHOULD BE EXITING THE REGION BY
03Z...HOWEVER ACTUAL BAROCLINIC ZONE IS HELD UP IN CONTINUED DEEP
SOUTHWEST FLOW. THUS WILL SEE CONTINUED RAIN SHOWER CHANCES
OVERNIGHT...ESPECIALLY ACROSS SOUTHEASTERN ZONES. SOME PATCHY FOG
ALSO POSSIBLE. WITH DEVELOPING WESTERLY FLOW...MAY SEE SOME
UPSLOPE RAIN/SNOW SHOWERS DEVELOP TOWARDS MORNING ALONG THE
ALLEGHENY FRONT. LOWS IN THE 30S/40S.
FRONTAL ZONE STILL SLOW TO MOVE EASTWARD ON THURSDAY/THURSDAY
NIGHT SO HAVE KEPT CHANCES IN FOR SOUTHEASTERN MARYLAND. MORE
PRONOUNCED NORTHWEST FLOW WILL BE DEVELOPING SO ALSO HAVE CHANCES
FOR UPSLOPE RAIN/SNOW SHOWERS ALONG THE ALLEGHENY FRONT. WILL BE
LOOKING AT HIGHS IN THE 40S TO LOW 50S.
HIGH PRESSURE WILL FINALLY BUILD INTO THE REGION ON FRIDAY WITH
SKIES CLEARING. WILL SEE NEAR NORMAL TEMPERATURES WITH HIGHS IN
THE 40S FOR MOST.
&&
.LONG TERM /SATURDAY THROUGH TUESDAY/...
A POTENTIALLY ACTIVE WEATHER PATTERN MAY SETUP FOR THE
PERIOD...BUT UNCERTAINTY IN THE DETAILS REMAINS HIGH THIS FAR OUT.
A POTENT UPPER-LEVEL RIDGE OF HIGH PRESSURE WILL DEVELOP OVER THE
WESTERN CONUS AND THIS WILL ALLOW FOR A STRONG UPPER-LEVEL TROUGH
TO CARVE OUT OVER THE CENTRAL AND EASTERN CONUS. SHORTWAVE ENERGY
DIVING INTO THE TROUGH WILL ENHANCE THE CHANCE FOR COASTAL STORMS
TO DEVELOP WHILE COLDER AIR REMAINS IN PLACE.
FOR SATURDAY...HIGH PRESSURE WILL REMAIN OVERHEAD BRINGING DRY AND
SEASONABLY CHILLY CONDITIONS. HOWEVER...COASTAL LOW PRESSURE WILL
LIKELY DEVELOP SATURDAY NIGHT OFF THE SOUTHEAST COAST AS SHORTWAVE
ENERGY IN THE SOUTHERN STREAM OF THE JET DIGS DOWN AND INTERACTS
WITH THE BAROCLINIC ZONE ALONG THE COAST. IT DOES APPEAR THAT THIS
SYSTEM WILL DEVELOP TOO LATE TO HAVE A SIGNIFICANT IMPACT ON OUR
WEATHER. THAT IS BECAUSE MORE SHORTWAVE ENERGY WILL BE DIVING INTO
THE CENTRAL CONUS...ALLOWING THIS SYSTEM TO PUSH FARTHER EAST THAN
NORTH. THIS WOULD KEEP THE LOW TOO FAR TO OUR SOUTH BUT THIS WILL
HAVE TO BE MONITORED SINCE IT IS STILL SEVERAL DAYS OUT.
THE SYSTEM DIVING INTO THE CENTRAL CONUS SUNDAY MAY DEVELOP INTO A
COASTAL LOW DURING THE EARLY PORTION OF NEXT WEEK. LATEST
DETERMINISTIC GFS AND ECMWF SHOW THIS HAVING A BETTER CHANCE OF
IMPACTING OUR AREA. THE GEFS MEAN SHOWS A STRONG UPPER-LEVEL TROUGH
OVERHEAD WHICH WOULD ALSO SUPPORT THE POSSIBILITY OF A COASTAL LOW.
CONFIDENCE IS HIGH FOR A HIGH AMPLITUDE PATTERN WITH A POTENT UPPER-
LEVEL TROUGH OVERHEAD SATURDAY THROUGH TUESDAY...BUT THE DETAILS AND
TIMING OF THE SHORTWAVE ENERGY ARE HIGHLY UNCERTAIN WHICH LEADS TO A
LOW CONFIDENCE FORECAST. HOWEVER...AS OF NOW IT APPEARS THAT
SATURDAY AND SUNDAY WILL TURN OUT DRY AND SEASONABLY CHILLY. A
COASTAL STORM MAY BRING THE CHANCE FOR WINTRY PRECIPITATION TO THE
AREA EARLY NEXT WEEK.
&&
.AVIATION /15Z WEDNESDAY THROUGH SUNDAY/...
CONDITIONS DROPPING QUICKLY THIS MORNING WITH RAIN MVG INTO THE
REGION WITH LIFR-IFR BEING REPORTED AT ALL TAF SITES. EXPECTING
THE DIMINISHED CONDITIONS TO PERSIST THRU 17-19Z. WINDS LESS THAN
10 KTS AT THE SFC...WITH 45-50 KTS AT 2KFT.
FOR THIS AFTN...LOW-MOD CONFIDENCE ON THE CIGS/VIS. GUIDANCE
SUGGESTS IMPROVEMENT TO MVFR IF NOT VFR FOR THE AREA OUTSIDE OF
THE CONVECTIVE ACTIVITY. ALONG THE COLD FRONT...A LINE OF HEAVIER
SHOWERS TO ISO TSTM COULD BRING CONDITIONS DOWN TO IFR. HAVE
INCLUDED IN TEMPOS IN 15Z ISSUANCE TO REFLECT TIMING. WINDS HAVE A
BETTER CHC OF GUSTING KCHO/KDCA/KBWI/KMTN...WITH STRONG WINDS
STILL EXPECTED AT 2 KFT THRU THE AFTN...35-45 KTS.
SHOWERS WILL TAPER OFF LATER THIS EVENING AND TONIGHT. THERE MAY
BE LINGERING AREAS OF LOW CEILINGS AND VISIBILITIES...BUT SHOWING
A GENERAL IMPROVEMENT FOR NOW. WINDS WILL TURN WEST-NORTHWESTERLY
BY THURSDAY MORNING.
WIDESPREAD VFR WILL DEVELOP FOR THURSDAY AND FRIDAY...PERSISTING
INTO SATURDAY AND SUNDAY. LOW PRESSURE MAY IMPACT THE TERMINALS
EARLY NEXT WEEK. DETAILS ARE HIGHLY UNCERTAIN AT THIS TIME.
&&
.MARINE...
MARGINAL SCA CONDITIONS ON THE MIDDLE CHESAPEAKE BAY THIS
MORNING...EXPECTING TO INCREASE THRU THE DAY. SMALL CRAFT
ADVISORY REMAINS IN EFFECT THROUGH TODAY AND INTO THIS EVENING
WITH GUSTS UP TO 25-27 KNOTS. HAVE ALSO KEPT LINGERING SCA ON THE
CHESAPEAKE BAY AND LOWER TIDAL POTOMAC FOR TONIGHT.
RAIN IS ALSO EXPECTED TODAY...WITH THE POSSIBILITY FOR ISOLATED
THUNDERSTORMS THIS AFTERNOON/EVENING. LOCALLY HIGHER GUSTS MAY
ACCOMPANY SOME OF THE HEAVIER STORMS...WITH SMW POTENTIALLY
NEEDED.
WINDS WILL SLACKEN ON THURSDAY MORNING...BUT AN ADDITIONAL SCA MAY
BE NEEDED THURSDAY NIGHT INTO FRIDAY WITH DEVELOPING NORTHWEST
FLOW.
HIGH PRESSURE WILL BUILD OVER THE WATERS LATER FRIDAY AND SATURDAY.
LOW PRESSURE WILL LIKELY STAY WELL SOUTH AND EAST OF THE WATERS
SUNDAY THROUGH SUNDAY NIGHT. THE GRADIENT MAY BE ENOUGH FOR WIND
GUSTS TO APPROACH SCA CRITERIA THOUGH. ANOTHER COASTAL LOW MAY
IMPACT THE WATERS EARLY NEXT WEEK. TIMING AND DETAILS REMAIN
UNCERTAIN THIS FAR OUT.
&&
.HYDROLOGY...
TEMPERATURES ARE STARTING OFF THE DAY IN THE 40S WITH RAIN
OVERSPREADING THE AREA. TO THE WEST OF THE DIVIDE...TEMPERATURES ARE
IN THE MID 50S...AND THAT AIRMASS WILL EVENTUALLY GET TO MOST IF NOT
ALL OF THE AREA. WHILE THE WARMEST TEMPERATURES AND HIGHEST
DEWPOINTS WILL BE IN THE AREA WHERE THE SNOWPACK IS ALREADY GONE...
CONDITIONS WILL BE FAVORABLE TO MELT MUCH OF THE REMAINING SNOW.
SMALL STREAMS HAVE HAD THE OPPORTUNITY TO RECEDE A BIT FROM THE
CRESTS ON MONDAY...WHILE LARGER STREAMS CONTINUE TO STEADILY RISE.
PARTIAL ICE BLOCKAGES MAY STILL BE A FACTOR...ESPECIALLY IN THE
EASTERN WV PANHANDLE AND NORTHERN MARYLAND. ICE WAS ALSO REPORTED
MOVING DOWN THE MIDDLE POTOMAC YESTERDAY BUT IT DOES NOT APPEAR IT
IS CAUSING A SUBSTANTIAL BLOCKAGE AT THIS TIME.
CONFIDENCE IS NOW HIGH FOR AT LEAST SOME FLOOD POTENTIAL DUE TO THE
COMBINATION OF SNOWMELT AND RAIN OF AROUND ONE INCH IN MOST AREAS.
THE HIGHEST RISK AREA IS IN THE FAR EASTERN WV PANHANDLE AND
NORTHERN MD...BUT SOME URBAN FLOODING AND POTENTIALLY SIGNIFICANT
PONDING OF WATER IS POSSIBLE IN THE URBAN CORRIDOR ESPECIALLY DUE TO
PLOW-PILE-COVERED STORM DRAINS.
RIVER FLOOD WARNINGS ARE CURRENTLY IN EFFECT FOR THE CACAPON AND
OPEQUON FOR FLOODING LATER TODAY AND TOMORROW. A RIVER FLOOD WATCH
WAS ISSUED FOR THE MAINSTEM SHENANDOAH YESTERDAY AND FOR THE
MAINSTEM POTOMAC FROM WILLIAMSPORT TO LITTLE FALLS THIS MORNING.
WATCHING THE REMAINING TRIBUTARIES AND THE UPPER TIDAL POTOMAC BUT
CONFIDENCE IS NOT HIGH ENOUGH YET FOR A WATCH IN ANY OF THOSE AREAS.
&&
.TIDES/COASTAL FLOODING...
SOUTHERLY FLOW WILL INCREASE TODAY WHICH WILL CAUSE TIDAL
ANOMALIES TO INCREASE. GUIDANCE CONTINUES TO SHOW MINOR FLOODING
LATER THIS AFTERNOON AND EVENING ACROSS THE NORTHERN PORTION OF
THE CHESAPEAKE BAY NEAR BOWLEYS QUARTERS AND HAVRE DE GRACE.
BALTIMORE AND ANNAPOLIS ARE CLOSE...BUT GUIDANCE CONTINUES TO SHOW
WATER LEVELS JUST BELOW MINOR FLOODING THRESHOLDS. A NORTHWEST
FLOW WILL DEVELOP LATE TONIGHT INTO THURSDAY. TIDAL ANOMALIES WILL
DROP DURING THIS TIME.
