AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC
257 PM EST WED JAN 20 2016
.SYNOPSIS...
AN UPPER-LEVEL DISTURBANCE WILL PASS THROUGH THE AREA THIS
EVENING. CANADIAN HIGH PRESSURE WILL BUILD IN OVERNIGHT THROUGH
THURSDAY NIGHT. HIGH IMPACT WINTER STORM EXPECTED TO AFFECT THE
REGION FRIDAY THROUGH SATURDAY NIGHT. HIGH PRESSURE BUILDS FOR
EARLY NEXT WEEK WITH IMPROVING CONDITIONS.
&&
.NEAR TERM /THROUGH THURSDAY/...
AN UPPER-LEVEL DISTURBANCE AND ITS ASSOCIATED COLD FRONT OVER THE
OHIO VALLEY LATE THIS AFTERNOON WILL PASS THROUGH OUR AREA
TONIGHT. MOST OF THE FORCING IS ALONG AND AHEAD OF THE SHORTWAVE
ENERGY...AND LATEST GUIDANCE CONTINUES TO SUGGEST THAT THE FORCING
WILL BE JUST STRONG ENOUGH TO OVERCOME LOW-LEVEL DRY AIR CURRENTLY
IN PLACE. THIS MEANS THAT A PERIOD OF SNOW IS LIKELY THIS
EVENING...ESPECIALLY ACROSS CENTRAL VIRGINIA AND FOR LOCATIONS
NEAR AND EAST OF THE BLUE RIDGE MOUNTAINS. ANY SNOW WILL BE
LIGHT...BUT WITH COLD PAVEMENT TEMPERATURES SLIPPERY CONDITIONS
ARE LIKELY DURING THE EVENING RUSH. A WINTER WEATHER ADVISORY IS
IN EFFECT FOR THE WASHINGTON METROPOLITAN AREA INTO SOUTHERN
MARYLAND AND THE VIRGINIA PIEDMONT FOR LIGHT SNOW ACCUMULATIONS
AROUND THE RUSH HOUR.
THE UPPER-LEVEL DISTURBANCE AND COLD FRONT WILL MOVE AWAY FROM THE
AREA OVERNIGHT AND A REINFORCING SHOT OF COLD AIR IS EXPECTED
AHEAD OF HIGH PRESSURE OVER THE OHIO VALLEY. MIN TEMPS WILL RANGE
FROM THE SINGLE DIGITS AND TEENS IN THE ALLEGHENY HIGHLANDS TO THE
LOWER AND MIDDLE 20S IN DOWNTOWN WASHINGTON AND BALTIMORE.
HIGH PRESSURE WILL BUILD OVERHEAD THURSDAY...BRINGING DRY AND
SEASONABLY COLD CONDITIONS DESPITE SUNSHINE.
&&
.SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY NIGHT/...
LOW PRESSURE IN THE SOUTHERN STREAM OF THE JET WILL INTENSIFY AS
IT TRACKS THROUGH THE GULF COAST STATES THURSDAY NIGHT. HIGH
PRESSURE WILL BUILD BUILD OVER NEW ENGLAND AND THE SURFACE RIDGE
AXIS WILL EXTEND INTO OUR AREA. CLOUDS WILL INCREASE WELL AHEAD OF
THE STORM SYSTEM...BUT IT SHOULD REMAIN FAR ENOUGH FOR DRY
CONDITIONS TO PERSIST.
THE LOW WILL TRACK INTO THE TENNESSEE FRIDAY AND COASTAL LOW
PRESSURE WILL DEVELOP OFF THE SOUTHEAST COAST. THIS SYSTEM WILL
CUTOFF...CAUSING LOW PRESSURE TO INTENSIFY AND TRACK SLOWLY DURING
THIS TIME. PLENTY OF COLD AIR WILL CONTINUE TO FILTER ITS WAY IN
FROM THE NORTH DUE TO HIGH PRESSURE OVER NEW ENGLAND. SNOW IS
EXPECTED TO OVERSPREAD THE AREA FROM SOUTHWEST TO
NORTHEAST...FIRST DURING THE MORNING AND MIDDAY HOURS ACROSS
CENTRAL VIRGINIA AND THEN LATER IN THE AFTERNOON OR EARLY EVENING
HOURS ACROSS THE WASHINGTON AND BALTIMORE METROPOLITAN AREAS INTO
NORTHERN MARYLAND.
THE COASTAL LOW WILL SLOWLY MOVE UP THE MID-ATLANTIC COAST FRIDAY
NIGHT THROUGH SATURDAY WHILE THE CUTOFF UPPER-LEVEL LOW ROTATES
THROUGH OUR AREA. LATEST GUIDANCE CONTINUES TO BE IN GOOD
AGREEMENT AS FAR AS INTENSITY AND THE TRACK OF THIS SYSTEM...WHICH
PUTS OUR CWA IN A FAVORABLE ZONE FOR A PROLONGED PERIOD OF
MODERATE TO HEAVY SNOW FRIDAY NIGHT THROUGH SATURDAY. LEANED
FORECAST TOWARD AN ENSEMBLE BLEND FOR QPF AND SNOWFALL TOTALS
THROUGH SATURDAY. THE MOST LIKELY SNOWFALL ACCUMULATION FORECASTS
ARE AROUND 1 TO 2 FEET THROUGH SATURDAY. WANT TO EMPHASIZE THAT
ALTHOUGH GUIDANCE IS IN GOOD AGREEMENT...ANY SMALL SHIFT IN THE
TRACK OF THIS SYSTEM WILL HAVE A SIGNIFICANT IMPACT ON THE
FORECAST. THE LOW WILL BE QUITE STRONG GIVEN THE BAROCLINIC ZONE
BETWEEN THE OCEAN AND COLD AIR OVER LAND AND THE POTENT DYNAMICS
AND DIFLLUENCE FROM THE UPPER-LEVEL LOW. THIS MEANS THAT WINDY
CONDITIONS ARE EXPECTED. THE STRONGEST WINDS SHOULD BE NEAR AND
EAST OF THE WASHINGTON AND BALTIMORE METROPOLITAN AREAS. A
BLIZZARD WATCH IS IN EFFECT FOR THESE AREAS AND A WINTER STORM
WATCH IS IN EFFECT ELSEWHERE. WINDS HAVE THE POTENTIAL TO BE QUITE
STRONG...AROUND 50 KNOTS NEAR THE WESTERN SHORE OF THE BAY.
THE COMBINATION OF HEAVY SNOW...BLOWING SNOW AND GUSTY WINDS WILL
CAUSE A VERY DANGEROUS SITUATION FRIDAY THROUGH SATURDAY. PLEASE
TAKE THE NECESSARY STEPS TO AVOID HAVING TO TRAVEL IF POSSIBLE
DURING THIS TIME.
THE LOW WILL FINALLY MOVE OFF THE COAST SATURDAY NIGHT AND SNOW
SHOULD GRADUALLY TAPER OFF DURING THIS TIME. ADDITIONAL SNOWFALL
ACCUMULATIONS ARE LIKELY BEFORE SNOWFALL ENDS. GUSTY WINDS ALONG
WITH BLOWING AND DRIFTING SNOW WILL CONTINUE OVERNIGHT.
&&
.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
HIGH PRESS BUILDS IN ON SUN. SOME SNOW SHOWERS MIGHT STILL LINGER
TO THE EASTERN HALF OF THE CWA... BUT THAT SHOULD BE CLEARING
THROUGH THE DAY. DRY CONDITIONS EXPECTED THROUGH TUE BEFORE THE
NEXT SYSTEM IMPACTS OUR AREA. ECMWF IS DRIER THAN GFS FOR THIS
SYSTEM... KEEPING PRECIP OVER OUR WESTERN COUNTIES. HIGH TEMPS
WILL BE IN THE 30S SUN THRU MON... INCREASING TO THE 40S TUE AND
WED. LOW TEMPS WILL BE INCREASING FROM THE TEENS SUN NIGHT TO THE
20S MON AND TUE NIGHT.
&&
.AVIATION /19Z WEDNESDAY THROUGH MONDAY/...
AN UPPER-LEVEL DISTURBANCE WILL LIKELY BRING A PERIOD OF LIGHT
SNOW TO THE TERMINALS THIS EVENING. THE BEST CHANCE WILL BE
BETWEEN 22 AND 03Z. HAVE MVFR CONDITIONS IN THE TAFS BUT IFR
CONDITIONS ARE POSSIBLE DURING THIS TIME. VFR CONDITIONS WILL
RETURN BEHIND THIS SYSTEM THROUGH THURSDAY NIGHT.
A MAJOR WINTER STORM WILL IMPACT THE TERMINALS BEGINNING FRIDAY.
SNOW WILL OVERSPREAD KCHO DURING THE MORNING OR MIDDAY HOURS AND
THEN THE REST OF THE TERMINALS DURING THE AFTERNOON OR EARLY
EVENING HOURS. SNOW WILL BE HEAVY AT TIMES THROUGH SATURDAY
EVENING BEFORE TAPERING OFF OVERNIGHT. SUBIFR CONDITIONS ARE
EXPECTED DURING THIS TIME ALONG WITH GUSTY WINDS.
HIGH PRESSURE WILL RETURN FOR SUNDAY AND MONDAY.
&&
.MARINE...
A COLD FRONT WILL PASS THROUGH THE WATERS TONIGHT. NORTHWEST WINDS
WILL INCREASE BEHIND THE FRONT TOWARD MORNING. A SMALL CRAFT
ADVISORY IS IN EFFECT FOR THE WATERS LATE TONIGHT THROUGH MIDDAY
THURSDAY. WINDS WILL DIMINISH AS HIGH PRESSURE RETURNS THURSDAY
AFTERNOON INTO THURSDAY NIGHT.
STRONG LOW PRESSURE WILL DEVELOP OFF THE SOUTHEAST COAST LATE
FRIDAY AND IT WILL SLOWLY TRACK UP THE MID-ATLANTIC COAST THROUGH
SATURDAY EVENING. NORTHEAST WINDS WILL INTENSIFY DURING THIS TIME.
A GALE WARNING WILL LIKELY BE NEEDED FOR THE WATERS FRIDAY NIGHT
AND STORM FORCE WINDS ARE POSSIBLE SATURDAY INTO SATURDAY NIGHT.
THE LOW SHOULD MOVE AWAY FROM THE WATERS LATE SATURDAY NIGHT
THROUGH SUNDAY. WINDS WILL GRADUALLY DIMINISH DURING THIS
TIME...BUT HEADLINES WILL LIKELY BE NEEDED. HIGH PRESSURE WILL
BUILD OVER THE WATERS SUNDAY NIGHT INTO MONDAY BEFORE ANOTHER COLD
FRONT AND ITS ASSOCIATED LOW PRESSURE POSSIBLY IMPACT THE WATERS
DURING THE MIDDLE PORTION OF NEXT WEEK.
&&
.TIDES/COASTAL FLOODING...
WATER LEVEL ANOMALY REMAINS ONE FOOT BELOW ASTRONOMICAL PREDICTION
FROM STRONG NWLY FLOW LAST NIGHT. WATER LEVELS WILL SLOWLY RETURN TO
NORMAL THROUGH THURSDAY.
UNCERTAINTY REMAINS WITH THE COASTAL FLOODING POTENTIAL FRIDAY AND
SATURDAY AS A NOR'EASTER MOVES ACROSS SERN VA. THE PROLONGED NELY
FLOW SHOULD RAISE WATER LEVELS ABOVE NORMAL...PARTICULARLY FOR
SOUTHERN MD WATERS (SOUTH OF ANNAPOLIS). MINOR COASTAL FLOODING IS
POSSIBLE FOR CALVERT AND ST MARYS COUNTY. THERE IS A FULL MOON
SATURDAY...SO IT WILL NOT TAKE MUCH TO CAUSE MINOR FLOODING.
NELY GALES FRIDAY NIGHT THROUGH SATURDAY WILL CAUSE BATTERING WAVES.
ALONG THE WESTERN SHORE OF THE BAY WHICH COULD CAUSE SOME INUNDATION
AS WELL AS PIER DAMAGE.
