The episode as NWS LWX wrote it up.
A strong cold front pushed south across the Mid Atlantic during the afternoon of March 5th. While there was no precipitation associated with the front, strong gusty winds affected the region during the afternoon of March 5th and even into March 6th. These strong winds downed trees and power lines in Frederick County on March 6th.

HIGH PRESSURE CENTERED OVER THE GREAT LAKES WILL MOVE OVER THE AREA
AND BE CENTERED OVER THE MID ATLANTIC BY MIDNIGHT TUE NIGHT. GUSTY
WINDS THIS MORNING WILL GRADUALLY SUBSIDE THIS AFTERNOON AND RAPIDLY
SUBSIDE TONIGHT. HIGH CLOUDS WILL BEGIN TO STREAM IN LATER THIS
AFTERNOON AND GRADUALLY LOWER AND THICKEN DURING THE NIGHT.
CLIPPER DIVING DOWN WILL BRING SNOW DOWN TO THE REGION WITH SLIGHT
CHC POPS IN S MD FOR THE OVERNIGHT MON NIGHT...UP TO CATAGORICAL
POPS FOR OUR NW COUNTIES. MORE ON THAT SYSTEM IN THE LONG TERM
DISCUSSION BELOW. ANY PRECIP DURING THE OVERNIGHT WOULD BE SNOW.
FIRE CONDITIONS WILL AGAIN BE A PROBLEM TODAY WITH GUSTY WINDS AND
VERY DRY AIR. DEWPOINTS ARE FORECAST TO FALL BELOW ZERO THIS
AFTERNOON. WINDS AT THE TIME ARE EXPECTED TO BE SLIGHTLY BELOW
CRITERIA BUT CERTAINLY WILL BE ANOTHER DAY OF CAUTION WITH FIRE
CONDITIONS AFTER YESTERDAYS RED FLAG.
AVIATION /08Z-06Z/...
GUSTY SFC WINDS AROUND 30KT THIS MORNING WILL BE THE ONLY CONCERN
THROUGH THE TAF PERIOD 06Z-06Z. EXPECT VFR CONDITIONS THROUGH 06Z
WED. BETWEEN 06Z AND 12Z WED SOME LOWER CIGS AND VSBY COULD MOVE IN
WITH SNOW SHOWERS FROM THE NW.
MARINE...
STRONG SMALL CRAFT ADVISORY CONDITIONS WILL PERSIST UNTIL LATE
AFTERNOON OR EVENING. 30 KT GUSTS ARE EXPECTED THIS MORNING. WINDS
WILL RAPIDLY DIMINISH AFTER SUNSET AS THE AXIS OF THE HIGH PRESSURE
AREA MOVES THROUGH.
LONG TERM /WEDNESDAY THROUGH MONDAY/...
CLIPPER SYSTEM WILL MOVE ACROSS THE FORECAST AREA FROM NORTHWEST TO
SOUTHEAST ON WEDNESDAY...THEN OFFSHORE LATE WEDNESDAY NIGHT BEFORE
RAPIDLY INTENSIFYING. THERE IS SOME INCONSISTENCY WITH HOW FAR SOUTH
THIS CLIPPER WILL DIVE...WHICH COULD LIMIT THE SNOWFALL AMOUNTS
ACROSS THE NORTHERN TIER OF COUNTIES ON THE PENNSYLVANIA STATE LINE.
THE TIMING DISCREPANCIES REMAIN BETWEEN THE NAM AND GFS...WITH THE
GFS ABOUT 6 HOURS FASTER THAN THE NAM. THIS HAS BEEN PRETTY COMMON
WITH THE PAST FEW STORM SYSTEMS...AND EACH TIME PRECIPITATION HAS
ARRIVED FASTER. HOWEVER...THIS IS MARCH AND THIS SYSTEM WILL BE
MOVING INTO A DRIER AIRMASS. WILL LEAN MORE TOWARDS THE GFS.
HAVE ISSUED A WINTER STORM WATCH FOR THE WESTERN ZONES OF THE
FORECAST AREA...ALLEGANY COUNTY IN MARYLAND...AND
GRANT...MINERAL...AND PENDLETON COUNTIES IN WEST VIRGINIA. LOOKS
LIKE THAT REGION WILL HAVE THE BEST CHANCE OF 5 INCHES OR MORE IN
ABOUT 12 HOURS. FURTHER EAST INTO WASHINGTON DC AND
BALTIMORE...BETWEEN 2 AND 4 INCHES ARE POSSIBLE. BIG QUESTION IS
WHERE THE RAIN/SNOW MIX LINE WILL FORM DURING THE AFTERNOON. WARM
ADVECTION WEDNESDAY MORNING MAY RAISE TEMPERATURES IN THE LOWER
LEVELS ENOUGH TO CHANGE RAIN/SNOW TO RAIN IN THE FAR SOUTH.
HOWEVER...IF THE SYSTEM INTENSIFIES AS MUCH AS THE GFS IS
INDICATING...LOWER SOUTHERN MARYLAND MAY SEE MORE SNOW AND LESS OF A
MIX. WILL LET LATER SHIFTS PIN THIS DOWN MORE.
COLD HIGH PRESSURE RETURNS FOR THE END OF THE WEEK BEFORE THE NEXT
CHANCE OF PRECIPITATION THIS WEEKEND. MADE NO CHANGES TO THE GRIDS
PAST FRIDAY.
