AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC
432 AM EDT MON OCT 29 2012

.SYNOPSIS...

HURRICANE SANDY IS APPROXIMATELY 390 MILES SOUTHEAST OF WASHINGTON
D.C. THE STORM IS FORECAST TO MOVE CLOSER TO THE COAST TODAY...AND
MOVE INLAND ACROSS SOUTHERN NEW JERSEY TONIGHT. 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 DURING THE SECOND HALF OF
THE WORK WEEK.

&&

.NEAR TERM /TODAY/...

06Z IAD SNDG IS IN.

HISTORIC WEATHER OVER THE NEXT 36 HOURS FOR THE CENTRAL MID ATLANTIC
AS SANDY MAKES LANDFALL. FOR A CONCISE SUMMARY OF THREATS AND THEIR
IMPACTS PLEASE SEE THE LATEST SPECIAL WEATHER STATEMENT ON
SANDY...SPSLWX. THERE IS A LINK TO THIS IN BIG RED LETTERS AT THE
TOP OF OUR WEBPAGE... WEATHER.GOV/LWX.

AS OF 08Z...THE CENTER OF HURRICANE SANDY IS MOVING QUICKLY TO THE
NORTH. IT IS NORTH OF CAPE HATTERAS AND PRETTY MUCH EVEN WITH THE
NC/VA BORDER. CONVERGENT WIND IS STILL APPARENT ACROSS THE LWX CWA
WITH NORTH-NORTHWESTERLY FLOW WEST OF I-95 AND NORTH-NORTHEASTERLY
EAST. THIS HAS KEPT THE HEAVY BANDS MOSTLY EAST OF THE WRN SHORE OF
THE BAY. LIGHT TO MODERATE RAIN WILL CONTINUE ACROSS THE REST OF THE
CWA THROUGH THE MORNING. SNOW IS ONGOING ABOVE ABOUT 3500 FT /KHSP
IS 34 AND MODERATE SNOW/. WHETHER THIS STAYS COLD/SNOW THROUGH THE
DAY IS A QUESTION...BUT ANY ACCUMULATIONS WOULD BE AT THE EXTREME
POINTS. TRUE ACCUMULATIONS ARE EXPECTED TO BEGIN AT LOWER ELEVATIONS
/SAY ABOVE 3000 FT/ THIS EVENING WHERE THE BLIZZARD WARNING IS IN
EFFECT.

SANDY WILL MAKE HER NORTHWEST THEN WEST TURN BEFORE MAKING
LANDFALL OVER SOUTHERN NEW JERSEY AS A POTENT POST-TROPICAL STORM
THIS EVENING. A COMBINATION OF THE POST-TROPICAL TRANSITION AND
TURN OF SANDY WILL BRING HEAVY RAIN BANDS MAINLY OVER THE NORTHERN
2/3 OF THE CWA. PLEASE PAY ATTENTION TO AREAL AND RIVER FLOOD
WARNINGS ISSUED THROUGH THIS EVENT. SEVERAL INCHES...PARTICULARLY
IN URBAN AREAS WILL BE QUITE IMPACT FULL.

&&

.SHORT TERM /TONIGHT/...

WORST OF THE WORST FOR LWX. THE WESTWARD INLAND TRACK OF
SANDY THEN MUDDIES WITH THE 00Z ECMWF/GFS ALONG THE MASON-DIXON LINE
AND THE 00Z NAM NORTH OF HARRISBURG PA. WIND DIRECTION PLAYS
DIRECTLY INTO THE LOCATION OF THE LOW CENTER. ONLY THING OF
CERTAINTY WIND WISE FOR TONIGHT WAS TO BACK FLOW TO WLY EARLIER...IN
THE EARLY MORNING TIMEFRAME. WIND GUSTS STILL EXPECTED IN EXCESS OF
60 MPH WITH 70 MPH CERTAINLY POSSIBLE...PARTICULARLY NORTH FROM DC.
WILL HAVE TO WATCH FOR WESTERLY FLOW LIMITING PRECIP LATE TONIGHT.

&&

.LONG TERM /TUESDAY THROUGH SUNDAY/...

WE ARE CONCERNED BECAUSE THE MDLS ARE IN CONSENSUS REGARDING THE CUTOFF
LOW STALLING OVR CENTRAL MD TUE. HVY RAINS WILL EXACERBATE THE FLD
THREAT. AN XCLNT HYDRO SXN IS BLO.

THERE RMNS PTNTL FOR A PROLONGED UPSLOPE SNOW IN THE FAR WEST. MAIN
FOCUS SHOULD BE ON IMPACTS...WHICH LOOK TO BE SIGNIFICANT. IT'S
PRETTY AMAZING TO SEE THAT JUST LAST YR - OCT 29/30...A NOR'EASTER
BROUGHT HVY WET SNOW FM THE HIGHER ELEVS OF ERN W.V./WRN MD TO NEW
ENGLAND. THIS CAUSED SIGNIFICANT POWER OUTAGES IN THE NERN U.S.
FEAR IS THIS IMPACT WL HAPPEN AGN. METEOROLOGICALLY THIS STORM IS
SOMEWHAT UNCHARTERED TERRITORY...AND SNOWFALL AMTS ARE DIFFICULT
TO GET AN EXACT HANDLE ON. ELEVATION LOOKS TO BE A KEY FACTOR. FOR
NOW WE ARE LOOKING AT 2000 FT AS BEING THE KEY HGT. IN HIGHLAND CO
THE TOWN OF MONTEREY IS AT 2900 FT. DRIVING N TO PENDLETON CO THE
ELEVATION IN FRANKLIN IS 1800 FT - THIS COULD LEAD TO BIG
DIFFERENCES IN TOTALS FOR TOWNS JUST 21 MILES APART.

THE THREAT OF UPSLOPE SNOW CONTINUES THRU MUCH OF THE WK...PROBABLY
INTO THURSDAY. 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.

E OF THE MTNS...2ND HALF OF THE WK 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 /09Z MONDAY THROUGH FRIDAY/...

CIGS NEAR IFR THROUGH THE DAY WITH LOWERING VSBYS AS HEAVIER RAIN
SPREADS WEST ACROSS THE TERMINALS MIDDAY INTO TONIGHT. WLY FLOW MAY
RAISE CIGS INTO MVFR LATE TONIGHT INTO TUESDAY AS PRECIP CONTINUES.
WINDS MOST IMPACT FULL WITH NLY GUSTS INCREASING ABOVE 30 KT THIS
MORNING...QUICKLY INCREASING TO NWLY 45 TO 50 KT BY LATE THIS
AFTERNOON. POSSIBLE NW 55 KT GUSTS TONIGHT NORTH FROM KDCA.

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...

HURRICANE WIND WARNING...PARTICULARLY FOR NW WINDS GUSTING 50 TO
POSSIBLY 65 KT THIS AFTERNOON AND EVENING GOING DOWN THE BAY. STORM
WARNING FOR MID AND UPR TIDAL POTOMAC WITH GUSTS UP TO 55 KT
TONIGHT.

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...

WE HV 5-9 INCHES OF RAIN 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...

NORTHERLY FLOW INCREASING THROUGH THE DAY. NORTHERN PART OF THE BAY
WILL SEE BLOW OUT THROUGH THIS EVENING...BEFORE THE QUICKLY SURGING
BACK UP THE BAY TUESDAY MORNING. WILL DROP THE COASTAL FLOOD
ADVISORY FOR ANNE ARUNDEL AND NORTH FOR TODAY...THEN CONTINUE THE
COASTAL FLOOD WARNING FOR LATE TONIGHT THROUGH TUESDAY NIGHT.

METROPOLITAN AREAS, INCLUDING THE MARYLAND PORTION OF THE
CHESAPEAKE BAY, TIDAL POTOMAC RIVER, MARYLAND FROM THE WESTERN
