Area forecast discussion, Oct 28, 3:51 PM EDT, 4 hours 49 minutes before
AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC
351 PM EDT SUN OCT 28 2012
.SYNOPSIS...
HURRICANE SANDY REMAINS ABOUT 500 MILES SOUTHEAST OF WASHINGTON D.C.
THE STORM IS FORECAST TO CURVE TOWARD THE COAST ON MONDAY...AND MOVE
INLAND NEAR THE JERSEY SHORE MONDAY NIGHT. THE POST-TROPICAL CYCLONE
WILL THEN SLOWLY TRACK INLAND INTO PENNSYLVANIA. THIS LARGE STORM
WILL BRING SIGNIFICANT IMPACTS TO THE ENTIRE REGION THROUGH MIDWEEK.
CONDITIONS WILL IMPROVE FOR THE SECOND HALF OF THE WORK WEEK.
&&
.NEAR TERM /UNTIL 6 AM MONDAY MORNING/...
SANDY IS STILL EXPECTED TO MOVE TO THE NORTHEAST TONIGHT...
POSITIONED WELL OFF THE COAST OF SOUTHEAST VIRGINIA BEFORE SWINGING
BACK TO THE NORTHWEST MONDAY AND MONDAY NIGHT AND MAKING LANDFALL
ALONG THE JERSEY SHORE EARLY TUESDAY. PLEASE CONTINUE TO REFER TO
THE LATEST ADVISORIES FROM THE NATIONAL HURRICANE CENTER FOR UPDATES
TO THE POSITION/TRACK OF SANDY.
RAIN HAS BEEN ALIGNED ALONG THE EASTERN SHORE OF MARYLAND THROUGH
MUCH OF THE DAY WITH LITTLE WESTERN MOVEMENT. THE EXPECTATION IS FOR
THIS AREA OF RAIN TO SHIFT TO THE WEST THROUGH THE EVENING...AND FOR
ADDITIONAL RAIN TO DEVELOP TO THE WEST OF THIS EXISTING AREA OF
RAINFALL. RAIN WILL INITIALLY BE ON THE LIGHT SIDE...BUT AFTER
MIDNIGHT MODERATE TO LOCALLY HEAVY BANDS WILL START TO BECOME
APPARENT. WINDS WILL ALSO CONTINUE TO INCREASE THROUGHOUT THE
NIGHT...LIKELY REACHING 40 TO 45 MPH PRIOR TO DAYBREAK.
&&
.SHORT TERM /6 AM MONDAY MORNING THROUGH WEDNESDAY/...
AT THE START OF MONDAY...THE CENTER OF SANDY IS FORECAST TO BE
AROUND 400 MILES EAST-SOUTHEAST OF WASHINGTON. HOWEVER...AS WE
HAVE BEEN STRESSING...THIS IS AN EXPANSIVE STORM AND SO CONDITIONS
/WHICH ARE ALREADY BREEZY WITH RAIN SPREADING WEST OVER THE BAY/
WILL CONTINUE TO DETERIORATE DURING THE DAY MONDAY...AND KEEP
GOING DOWNHILL AFTER THAT. ALL THE DETAILS OF THE FORECAST ARE IN
OUR GRAPHICAL AND TEXT FORECAST PRODUCTS...BUT JUST AS A SUMMARY
OF WHAT TO EXPECT:
RAINFALL/FLOODING...WILL BE DISCUSSED IN HYDROLOGY SECTION BELOW.
FLOOD THREAT IS SIGNIFICANT SO PLEASE REFER TO THAT.
WINDS...WE ARE ALREADY GUSTING TO 30 MPH AT TIMES IN SPOTS...AND
THAT WILL BE CONTINUING TO INCREASE. WE ARE EXPANDING THE HIGH
WIND WARNING TO START AT 8 AM MONDAY IN ALL AREAS...THOUGH IN SOME
OF THE WESTERN VALLEYS IT MAY STILL BE CLOSER TO NOON. A PROLONGED
PERIOD OF POWERFUL AND DANGEROUS WINDS IS EXPECTED...LASTING
LIKELY WELL INTO TUESDAY BEFORE GRADUALLY SUBSIDING. THIS
PROLONGED PERIOD OF WINDS WILL DO DAMAGE AND CREATE POWER OUTAGES.
SNOWFALL...YES...SNOWFALL. WE RAISED A WINTER STORM WATCH THIS
MORNING FOR HIGHLAND/PENDLETON AND WESTERN GRANT/MINERAL. WE WILL
RETAIN IT BECAUSE THERE IS SOME QUESTION WHETHER WE WILL BE FAR
ENOUGH AWAY FROM THE CENTER TO ALLOW THE COLD AIR TO GET IN TO OUR
FORECAST AREA. BUT IF IT IS COLD ENOUGH...THE POTENTIAL IS THERE FOR
HEAVY SNOW...AND HEAVY SNOW COMBINED WITH STRONG WINDS. EAST OF
THE WESTERN FRONT...THE SNOW THREAT IS EXTREMELY LOW.
TIDAL/COASTAL FLOODING...WILL BE DISCUSSED IN TIDAL/COASTAL SECTION
BELOW. THIS THREAT IS VERY COMPLEX SO REFER TO THAT SECTION FOR A
DETAILED DISCUSSION.
BOTTOM LINE...THIS IS A VERY DANGEROUS STORM WHICH WILL AFFECT
THE ENTIRE AREA REGARDLESS OF WHERE THE STORM CENTER IS. PLEASE
REFER TO THE SUITE OF HAZARDOUS WEATHER BULLETINS/WARNINGS FOR
EVEN MORE INFORMATION ABOUT THE IMPENDING STORM. ALSO PLEASE TAKE
THIS THREAT VERY SERIOUSLY...THIS IS GOING TO CREATE SIGNIFICANT
DISRUPTIONS OVER THE NEXT COUPLE DAYS. BE PREPARED TO AT LEAST
HUNKER DOWN FOR A WHILE...AND BE PREPARED FOR SOME SERIOUSLY
CHALLENGING CONDITIONS.
&&
.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
THE MAIN WEATHER STORY IN THE EXTENDED IS THE POTENTIAL FOR A
PROLONGED UPSLOPE PERIOD IN THE FAR WEST. WHILE THE INTENSITY OF
SUCH AN EVENT WOULD BE ABSOLUTELY NOTHING COMPARED TO THE EARLY PART
OF THE WEEK...IT KEEPS THE LIGHT PRECIP MACHINE TURNED ON...PROBABLY
THROUGH THURSDAY OR FRIDAY. THERE IS A SMALL RISK OF PRECIPITATION
MAKING IT EVEN BEYOND THE WESTERN FRONT INTO THE REST OF THE
HIGHLANDS...MAYBE EVEN UP TO THE BLUE RIDGE.
FOR EVERYONE ELSE...THE EXTENDED PERIOD WILL BE THE CALM AFTER THE
STORM. TEMPERATURES WILL BE 5 TO 10 DEGREES BELOW NORMAL THROUGHOUT
THE PERIOD...WITH HIGHS MAINLY IN THE 50S IN LOWS IN THE UPPER 30S
TO AROUND 40.
&&
.AVIATION /20Z SUNDAY THROUGH FRIDAY/...
NORTH/NORTHEAST WINDS WILL CONTINUE TO INCREASE OVER THE NEXT 24
HOURS...WITH SIGNIFICANT IMPACT FROM WINDS EXPECTED BEGINNING
MONDAY. EXPECT THE HUBS TO HAVE SUSTAINED WINDS ON MONDAY OF 25 TO
35 KT WITH GUSTS REACHING 45 TO 50 KT. SIMILAR OR STRONGER GUSTS ARE
EXPECTED MONDAY NIGHT INTO TUESDAY.
RAIN WILL TILT NORTHWEST...MAKING IT TO THE HUBS LATER THIS EVENING
AND SPREADING ACROSS THE ENTIRE AREA OVERNIGHT. THERE IS SOME
UNCERTAINTY REGARDING THE ONSET OF IFR OR LOWER CONDITIONS. THINKING
WAS THAT GUIDANCE WAS BRINGING THEM IN TOO EARLY...AND HAVE DELAYED
SEVERAL HOURS.
SEVERE IMPACTS ON AVIATION THROUGH TUESDAY WITH LOW CLOUDS...EXTREME
WINDS...AND HEAVY RAIN. CONDITIONS WILL SLOWLY IMPROVE TUESDAY NIGHT
AND NO IMPACTS TO AVIATION ARE EXPECTED FOR THE SECOND HALF OF THE
WEEK AT THE MAJOR TERMINALS.
&&
.MARINE...
WITH THE AFTERNOON PACKAGE...THE HURRICANE FORCE WIND WARNING IS NOW
IN EFFECT FOR THE ENTIRE MARYLAND CHESAPEAKE BAY AND ALL THE VARIOUS
INLETS...AND FOR THE LOWERMOST PORTION OF THE TIDAL POTOMAC RIVER.
IN THIS AREA...GUSTS OF 65 KNOTS ARE POSSIBLE MONDAY AND MONDAY
NIGHT. THE UPPER/MIDDLE TIDAL POTOMAC RIVER REMAINS UNDER A STORM
WARNING. BOTH OF THESE WARNINGS ARE IN EFFECT THROUGH TUESDAY.
WINDS REACHING/EXCEEDING SCA CRITERIA WILL CONTINUE ACROSS THE
MARINE AREA THROUGH AT LEAST WEDNESDAY...AND I ACTUALLY HAVE WIND
GUSTS MEETING SCA CRITERIA IN AT LEAST A PORTION OF THE WATERS
THROUGH MOST OF THE FORECAST PERIOD. HIGH PRESSURE COULD BUILD IN
AND WEAKEN THE WIND FIELDS BY NEXT WEEKEND.
&&
.HYDROLOGY...
THE LATEST RAINFALL PROJECTIONS HAVE COME IN HIGHER...AND WE WILL
NOW SAY THAT 5-9 INCHES OF RAIN IS POSSIBLE IN THE I-270 CORRIDOR
THROUGH THE DC METRO AREA AND DOWN THROUGH SOUTHERN MARYLAND.
AMOUNTS COULD BE EVEN HIGHER CLOSE TO THE BAY. 3-5 INCHES OF RAIN IS
EXPECTED IN THE NORTHERN HIGHLANDS AND RAPPAHANNOCK BASIN...WITH
LOWER AMOUNTS OF JUST 1-3 INCHES IN THE STAUNTON/WAYNESBORO/
CHARLOTTESVILLE/HARRISONBURG AREAS.
OUR RAINFALL PROJECTIONS HAVE OVER AN INCH OF RAIN PER SIX HOUR
PERIOD FOR 24 HOURS IN THE AREA WHERE THE HEAVIEST RAIN IS
ANTICIPATED. SOME FLASH FLOODING WOULD OCCUR IF MORE THAN THIS IS
EXPECTED...AND IS ALSO POSSIBLE WITH LOWER AMOUNTS IN AREAS WHERE
FALLEN LEAVES /OR PERHAPS OTHER WIND-DRIVEN DEBRIS/ MAY CLOG
DRAINAGE SYSTEMS. THESE FACTORS ALSO APPLY FOR LONGER-DURATION
STREAM FLOODING...WHICH IS LIKELY TO BE SIGNIFICANT AND LENGTHY...
EVEN ON STREAMS THAT ARE USUALLY FAST TO RISE AND FALL.
THE FLOOD THREAT BEGINS LATE TONIGHT. THE SMALLER STREAM AND URBAN
FLOOD THREAT CONTINUES THROUGH TUESDAY. THEN WE TURN ATTENTION TO
THE RIVER FORECAST LOCATIONS. AT THIS TIME...FIVE OF THOSE POINTS
/CONOCOCHEAGUE...MONOCACY...OPEQUON...SENECA...AND ANTIETAM/ ARE
FORECAST TO GO TO FLOOD. WE HAVE BEEN INCLUDING THAT IN THE FLOOD
WATCH BUT WARNING DECISIONS WILL LIKELY COME TONIGHT OR TOMORROW IF
THE FORECASTS HOLD...WHICH SO FAR...THEY HAVE.
IF EVERYTHING PLAYS OUT AS FORECAST...THE CREST MAY NOT GET DOWN TO
LITTLE FALLS UNTIL FRIDAY OR SATURDAY.
&&
.TIDES/COASTAL FLOODING...
THE TIDAL SITUATION IS VERY COMPLEX AND EVEN A LITTLE BIT CONFUSING.
BUT WILL TRY TO BREAK IT DOWN HERE. TIDAL ANOMALIES HAVE BEEN
BUILDING AND ARE IN THE 1 TO 2.5 FT RANGE ALREADY. THE LAST HIGH
TIDE WAS FAIRLY LOW AND THEREFORE WE DID NOT MEET CRITERIA...BUT
THIS ONE WE STAND A GOOD CHANCE. ADVISORY REMAINS OUT FOR ALEXANDRIA
AND THE ENTIRE WESTERN BAY AND LOWER TIDAL POTOMAC.
AS THE NORTHERLY/NORTHWESTERLY WINDS INCREASE...WE SHOULD BLOW OUT
THE HIGH WATER IN MOST OF OUR TIDAL REGION LATE TONIGHT AND
TOMORROW. AT THIS POINT THOUGH...WE WILL LEAVE THE EXISTING
ADVISORY IN PLACE UNTIL THE BLOWOUT STARTS. IT CAN ALWAYS BE
CANCELLED WHEN IT BEGINS.
ONCE THE STORM MOVES INLAND...WINDS WILL TURN OUT OF THE SOUTH LATE
MONDAY NIGHT THROUGH TUESDAY NIGHT AND STILL BE QUITE STRONG. THIS
WILL PUSH WATER UP THE BAY AND TIDAL POTOMAC...AND AT THAT TIME THE
TIDAL FLOOD THREAT MARKEDLY INCREASES. HAVE RAISED A COASTAL FLOOD
WARNING FROM MIDNIGHT MONDAY NIGHT THROUGH TUESDAY NIGHT. MODERATE
FLOODING IS POSSIBLE. A MAJOR FLOOD IS NOT EXPECTED AT THIS POINT.
THE WIND FIELD BEYOND TUESDAY NIGHT IS MUCH MORE UNCERTAIN...SO IT
IS NOT YET CLEAR WHETHER WE WILL REMAIN ELEVATED...GRADUALLY DROP...
OR PERHAPS BLOW OUT YET AGAIN.
