The episode as NWS LWX wrote it up.
A strong cold front swung through the Mid-Atlantic. Surge of cold air advection immediately and then again after the frontal passage resulted in two rounds of strong winds, one with a squall line that formed along the front and another more pro-longed with the synoptic flow.

50 KTS. THE 00Z SNDGS ARE INTERESTING - IAD SHOWS SOMEWHAT OF AN
INVRTED V WHILE PBZ IS QUITE MOIST TO ALMOST 400 MB.
COLD FRONT WL CROSS THE LWX CWA LATE THIS EVE/SHORTLY AFTR MDNGT.
HIGH WIND WARNING FOR NRN TIER OF COUNTIES IN MD (INCLUDING
BALTIMORE METRO) AND ALL COUNTIES WEST FROM THE BLUE
RIDGE/CATOCTIN MTN. 50 KT ARE ONLY IN THE GRIDS FOR HIGHER
ELEVATIONS WEST OF THE BLUE RIDGE...BUT NO ELEVATION WAS MENTIONED
IN THE NPWLWX BECAUSE OF THE LIKELY SURGE WITH THE COLD FRONT AND
OCCASIONAL GUSTS TO 50 KT (UP TO 60 MPH) IN THE TRAILING COLD AIR
ADVECTION. LEFT A WIND ADVISORY FOR THE DC METRO WHERE GUSTS LOOK
TO GENERALLY BE IN THE MID 40S FOR KNOTS (UP TO 50 MPH). SHOULD
THOSE GUSTS IN DC BE A LITTLE HIGHER THEN A HIGH WIND WARNING
WOULD BE NECESSARY. ALSO LEFT PORTIONS OF CENTRAL VA OUT OF THE
WIND ADVISORY BASED ON CLIMATOLOGY FOR COLD FRONT FROM THE WEST
WIND EVENTS.
EXPECT A SQUALL WITH THE FRONT...WITH SNOW ELEVATIONS QUICKLY
DROPPING TO ABOUT 700 FT AND ALL RAIN BELOW. ANY MEASURABLE SNOW
LOOKS TO BE ABOVE 1000 FT AND AN INCH OR TWO LOOKS TO BE RELEGATED
TO THE TYPICAL UPSLOPE AREAS WEST FROM THE ALLEGHENY FRONT.

LOW 50S S.

THE HIGH SIDE OF MIN-T GNDC. BELIEVE MOS IS GIVING TOO MUCH CREDIT
TO RADL COOLING.
LOPRES WL RIDE ALONG THIS BNDRY...AND WL EITHER BE CROSSING NE MD OR
PASSING JUST N OF THERE /LIKE METRO PHILLY/ BY MIDDAY MON. THIS WL
BE DRAGGING ANOTHER MEANINGFUL CDFNT ACRS THE CWFA MON AFTN. BEST
CHC AT PCPN WL BE COINCIDENT W/ THE FNT...AND HV LKLY POPS FOR THE
AFTN TIMEFRAME. GIVEN THE ISENT LIFT AHD OF IT THO...AM NOT
DISCOUNTING THE CHC DURING THE MRNG...SPCLY N OF SHD-DCA-NAK.

.LONG TERM /TUESDAY THROUGH SATURDAY/...
HIGH PRESSURE WILL BUILD INTO THE REGION TUESDAY AND TUESDAY
NIGHT...BRINGING IN COOLER AND DRIER AIR WHICH WILL LEAD TO MUCH
BELOW NORMAL TEMPERATURES...NEARLY 15 TO 20 DEGREES BELOW NORMAL.
COLD TEMPERATURES AND DRY AIR WILL LINGER WEDNESDAY AS HIGH PRESSURE
MOVES OFF OF THE COAST. A MODEST SOUTHERLY FLOW WILL DEVELOP DURING
THE DAY INTO WEDNESDAY NIGHT.
THE CHANCE OF RAIN SHOWERS AND PERHAPS A RUMBLE OF THUNDER OR TWO
RETURNS WEDNESDAY NIGHT WITH A BETTER CHANCE OF RAIN SHOWERS AND
THUNDERSTORMS THURSDAY AS A COLD FRONT APPROACHES WITH GOOD UPPER
LEVEL ENERGY SUPPORT.
THE THREAT FOR ADDITIONAL RAIN SHOWERS OR THUNDERSTORMS WILL LINGER
THURSDAY NIGHT AND FRIDAY WITH ADDITIONAL UPPER LEVEL ENERGY MOVING
INTO THE REGION.
HIGH PRESSURE WILL PUSH INTO THE REGION FRIDAY NIGHT AND SATURDAY
BEHIND THE STRONG UPPER LEVEL TROUGH. ANOTHER RUSH OF COLDER AND
DRIER AIR WILL FOLLOW.
THERE IS LITTLE CONFIDENCE AT THIS TIME THAT BOTH THE EUROPEAN AND
GFS MODEL TRY TO SNEAK ANOTHER UPPER LEVEL DISTURBANCE INTO THE
REGION FRIDAY NIGHT AND SATURDAY BEFORE THE HIGH REACHES US. FOR
NOW...WE WILL HOLD OFF ON POPS UNTIL THERE IS BETTER CONFIDENCE AS
TO HOW STRONG THE UPPER LEVEL TROUGH IS IN OUR REGION.
