The episode as NWS LWX wrote it up.
Prolonged event impacted the Mid-Atlantic. Southwest flow aloft overriding northeast flow at the surface from departing high pressure led to snow spreading over the region initially. Low pressure formed and organized over the Gulf of Mexico, eventually pushing off to the northeast and impacting the region on the 15th. As the cold air wedge was eroded away from this low, warming at all levels led to the snow transitioning to sleet and ice for most of the area.
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 Feb 14, 2:40 PM EST, 6 hours 20 minutes earlier.
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC
240 PM EST SUN FEB 14 2016
.SYNOPSIS...
ARCTIC HIGH PRESSURE OVERHEAD THIS AFTERNOON WILL MOVE OFF TO THE
EAST TONIGHT. LOW PRESSURE WILL IMPACT THE REGION MONDAY THROUGH
TUESDAY BRINGING SIGNIFICANT WINTRY PRECIPITATION. HIGH PRESSURE
BUILDS FOR THE MIDDLE AND LATTER PART OF THE WEEK.
&&
.NEAR TERM /THROUGH TONIGHT/...
ARCTIC HIGH PRESSURE WILL MOVE OFF TO THE EAST TONIGHT AND A
LONGWAVE TROUGH WILL CONTINUE TO DEVELOP OVER THE CENTRAL CONUS.
SHORTWAVE ENERGY ROTATING AROUND THE TROUGH WILL CAUSE LOW
PRESSURE TO DEVELOP OVER THE GULF COAST STATES.
WARM AND MOIST AIR FROM THE ATLANTIC AND GULF OF MEXICO WILL
OVERRUN THE ARCTIC AIR IN PLACE...RESULTING IN INCREASING CLOUDS
THIS EVENING. SNOW WILL OVERSPREAD THE AREA FROM SOUTHWEST TO
NORTHEAST LATE TONIGHT. NORTHEAST MARYLAND MAY REMAIN DRY FOR MOST
OF THE NIGHT DUE TO DRIER AIR.
&&
.SHORT TERM /MONDAY THROUGH WEDNESDAY/...
THE LOW WILL CONTINUE TO DEVELOP OVER THE GULF COAST STATES MONDAY
WHILE WARM AND MOIST AIR OVERRUN THE COLDER AIR IN PLACE. THIS
WILL CAUSE SNOW TO CONTINUE ACROSS THE AREA THROUGH MIDDAY WITH 2
TO 5 INCHES OF SNOW EXPECTED ACROSS MOST LOCATIONS. SNOW WILL
CHANGE OVER TO SLEET AND FREEZING RAIN AS WARMER AIR WORKS ITS WAY
IN ALOFT. THE CHANGE OVER TIME WILL OCCUR DURING THE AFTERNOON
HOURS FOR MOST LOCATIONS...BUT SNOW MAY HOLD ON A BIT LONGER NEAR
THE MASON-DIXON LINE AND IN THE ALLEGHENY HIGHLANDS.
WARMER AIR WILL CONTINUE TO WORK ITS WAY IN ALOFT MONDAY EVENING
CAUSING THE MAIN PTYPE TO BE FREEZING RAIN. LATEST GUIDANCE
CONTINUES TO SHOW THE LOW MOVING UP WEST OF THE APPALACHIANS LATER
MONDAY NIGHT INTO TUESDAY MORNING. THIS WILL CAUSE ENOUGH WARM AIR
TO WORK ITS WAY INTO THE AREA FOR PRECIPITATION TO CHANGE OVER TO
RAIN. EXACT CHANGEOVER TIMES TO RAIN ARE STILL A BIT
UNCERTAIN...BUT THE CURRENT FORECAST LEANS TOWARD THE GUIDANCE
THAT IS SLOWER IN ERODING THE COLD AIR. LOW-LEVEL COLD AIR CAN BE
TOUGH TO SCOUR OUT SINCE IT REMAINS TRAPPED NEAR THE SURFACE. ICE
ACCUMULATIONS WILL RANGE FROM LESS THAN ONE-TENTH OF AN INCH SOUTH
AND EAST OF WASHINGTON AND BALTIMORE...TO AROUND ONE-TENTH OF AN
INCH NEAR WASHINGTON AND BALTIMORE...TO AROUND A QUARTER INCH FOR
THE FAR NORTHERN AND WESTERN SUBURBS OF WASHINGTON/BALTIMORE AND
FOR LOCATIONS WEST OF THE BLUE RIDGE MOUNTAINS.
PRECIPITATION WILL BE LOCALLY HEAVY LATE MONDAY NIGHT THROUGH
MIDDAY TUESDAY AS THE LOW AND ITS UPPER-LEVEL SHORTWAVE PASS
THROUGH THE AREA. THE COMBINATION OF LOCALLY HEAVY RAINFALL AND
MELTING SNOW MAY CAUSE LOCALIZED FLOODING ISSUES. PRECIPITATION
AMOUNTS AROUND ONE INCH ARE POSSIBLE LATE MONDAY NIGHT INTO MIDDAY
TUESDAY.
PRECIPITATION WILL FINALLY TAPER OFF LATER TUESDAY AS THE LOW
MOVES AWAY FROM THE AREA.
ANOTHER UPPER-LEVEL DISTURBANCE WILL PASS THROUGH THE AREA TUESDAY
NIGHT. A FEW RAIN/SNOW SHOWERS ARE POSSIBLE. PRECIPITATION AMOUNTS
SHOULD BE LIGHT AND ANY SNOWFALL ACCUMULATION SHOULD BE LIGHT AS
WELL AND CONFINED MAINLY TO THE RIDGES AND FOR LOCATIONS
ALONG/WEST OF THE ALLEGHENY FRONT. HIGH PRESSURE WILL BUILD
TOWARD THE REGION WEDNESDAY...BRINGING DRY AND SEASONABLE
CONDITIONS.
&&
.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
THE MAIN UPPER LEVEL TROUGH OF LOW PRESSURE WILL SLIDE OFFSHORE THE
EAST COAST LATE WEDNESDAY NIGHT AND EARLY THURSDAY MORNING. BROAD
HIGH PRESSURE WILL MOVE IN FROM THE WEST AND DOMINATE THE REGION
THURSDAY THROUGH FRIDAY. A REINFORCING SHOT OF COLD AIR WILL BE
USHERED IN BY THIS RIDGE OF HIGH PRESSURE.
THE AREA OF HIGH PRESSURE WILL PUSH OFFSHORE TO ALLOW FOR A LIGHT TO
MODERATE SOUTHWEST FLOW TO DEVELOP ACROSS THE REGION FRIDAY NIGHT. AT
THE SAME TIME...A COLD FRONT WILL DRAG ALONG THE LOWER GREAT LAKES
AND OHIO VALLEY FROM A STORM SYSTEM OVER EASTERN CANADA. THROUGH
THE PERIOD FRIDAY NIGHT AND SATURDAY...THIS COLD FRONT WILL MOVE
ACROSS THE MID-ATLANTIC REGION AND BRING A CHANCE FOR SOME RAIN
SHOWERS. THERE ARE STILL DISCREPANCIES ON THE STRENGTH AND LOCATION
OF THE MAIN UPPER LEVEL TROUGH OF LOW PRESSURE THAT WILL BE
RESPONSIBLE FOR PUSHING THE SURFACE COLD FRONT THROUGH THE REGION.
THE GFS MODEL IS STILL FASTER WITH THE COLD FRONT THAN THE EUROPEAN
MODEL AT THIS TIME. TIMING ON PRECIPITATION FRIDAY NIGHT AND SATURDAY
COULD COINCIDE WITH LOW TEMPERATURES BELOW FREEZING TO PRODUCE SNOW
AT THE ONSET. AS OF NOW...WE HAVE A CHANCE FOR SOME RAIN SHOWERS.
HIGH PRESSURE WILL BUILD INTO THE REGION BRIEFLY SATURDAY NIGHT. THE
NEXT LOW PRESSURE SYSTEM SHOULD SCOOT EASTWARD ACROSS THE TENNESSEE
VALLEY INTO THE MID ATLANTIC REGION SUNDAY...BRINGING A CHANCE FOR
RAIN SHOWERS. WITH THIS LOW...THE GFS TENDS TO BE QUICKER THAN THE
EUROPEAN MODEL WITH MOVING THE LOW INTO THE MID ATLANTIC REGION.
&&
.AVIATION /19Z SUNDAY THROUGH FRIDAY/...
VFR CONDITIONS THROUGH THIS EVENING. SNOW WILL OVERSPREAD THE
TERMINALS LATE TONIGHT INTO MONDAY MORNING. SNOW WILL CHANGE OVER
TO SLEET AND FREEZING RAIN MONDAY AFTERNOON AND EVENTUALLY ALL
FREEZING RAIN MONDAY EVENING. WARMER AIR WILL WORK ITS WAY INTO
THE AREA...CAUSING PRECIPITATION TO CHANGE TO RAIN LATE MONDAY
NIGHT INTO TUESDAY. THE EXACT TIMING OF THE CHANGE OVER TO RAIN IS
STILL UNCERTAIN AT THIS TIME. SNOWFALL ACCUMULATIONS AROUND 2 TO 5
INCHES ARE EXPECTED WITH AROUND ONE-TENTH OF AN INCH OF ICE FROM
FREEZING RAIN ACROSS MOST OF THE TERMINALS. PERHAPS AROUND A
QUARTER INCH AT KMRB. IFR/SUBIFR CONDITIONS ARE EXPECTED ONCE THE
SNOW BEGINS LATE TONIGHT INTO TUESDAY MORNING.
CONDITIONS WILL IMPROVE LATER TUESDAY AND HIGH PRESSURE WILL BUILD
OVERHEAD WEDNESDAY.
VFR CONDITIONS WEDNESDAY NIGHT AND THURSDAY. WINDS NORTHWEST
AROUND 5 KNOTS WEDNESDAY NIGHT. WINDS BECOMING NORTH 5 KNOTS
THURSDAY.

HIGH PRESSURE WILL MOVE EAST OF THE WATERS TONIGHT. LOW PRESSURE
WILL APPROACH THE WATERS MONDAY BEFORE PASSING THROUGH LATE MONDAY
NIGHT INTO TUESDAY. A SMALL CRAFT ADVISORY MAY BE NEEDED FOR
PORTIONS OF THE WATERS LATE MONDAY NIGHT AND TUESDAY.
HIGH PRESSURE WILL BUILD TOWARD THE WATERS DURING THE MIDDLE
PORTION OF THE WEEK.
NO MARINE HAZARDS EXPECTED WEDNESDAY NIGHT AND THURSDAY.
