AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC
353 AM EDT FRI NOV 1 2013
.SYNOPSIS...
A STRONG AREA OF LOW PRESSURE OVER LAKE HURON THIS MORNING WILL
MOVE NORTHEAST INTO EASTERN CANADA WHILE ITS COLD FRONT CROSSES
THE AREA TODAY. THE FRONT WILL GRADUALLY PUSH THROUGH THE
CHESAPEAKE BAY REGION THIS AFTERNOON AND TONIGHT. AN UPPER TROUGH
MOVES THROUGH SATURDAY BEFORE HIGH PRESSURE BUILDS IN FROM THE
GREAT LAKES LATE IN THE WEEKEND. THE HIGH IS THEN EXPECTED TO MOVE
OFF THE EASTERN SEABOARD BY THE MIDDLE OF NEXT WEEK.
&&
.NEAR TERM /THROUGH TONIGHT/...
STRONG SOUTHERLY SYNOPTIC WINDS WILL GUST 25 TO 35 MPH THROUGH MID
MORNING. THIS IS A RESULT FROM A TIGHT PRESSURE GRADIENT BETWEEN A
1020 MILLIBAR HIGH OFF OF THE EAST COAST AND A 979 MILLIBAR LOW OVER
THE NORTHERN GREAT LAKES. GUSTS OVER 45 TO 55 MPH WILL BE
MORE LIKELY AT HIGHER ELEVATIONS OF THE BLUE RIDGE AND APPALACHIAN
MOUNTAINS. HENCE...THERE IS A WIND ADVISORY FOR AREAS ALONG AND WEST
OF THE BLUE RIDGE EARLY THIS MORNING. WINDS COULD STILL GUST 30-40
MPH THIS MRNG IN THE VLYS AND AREAS EAST OF THE BLUE RIDGE.
AS A COLD FRONT PUSHES TOWARD AND ACROSS OUR REGION TODAY...HEAVY
AND GUSTY SHOWERS AND PERHAPS A CLAP OF THUNDER OR TWO WILL
PROPAGATE EASTWARD. THE HEAVIEST OF RAINFALL AND WIND ASSOCIATED
WITH A QLCS LINE WILL MOVE THROUGH THE AREA THIS MORNING. RAIN
AMOUNTS WILL AVERAGE ONE QUARTER TO ONE HALF INCH WITH ISOLATED
HIGHER AMOUNTS IN THE WIDER BANDS OF SHOWERS OR ANY THUNDERSTORMS.
TEMPERATURES WILL REACH THEIR WARMEST LATE THIS MORNING OR EARLY
AFTERNOON...JUST BEFORE FRONTAL PASSAGE. HIGHS WILL BE ABOUT 10
DEGREES ABOVE NORMAL WITH MANY LOCATIONS CLOSING IN ON 70 DEGREES
ONCE AGAIN. EXPECT TEMPERATURES TO SLOWLY FALL THE REST OF THE
AFTERNOON INTO TONIGHT BUT STILL BOTTOMING OUT ABOVE NORMAL IN
MOST AREAS BY DAYBREAK ON SATURDAY.
CLOUDS AND EVEN A COUPLE OF RAIN SHOWERS MAY STILL LINGER ACROSS
EASTERN PARTS OF THE VIRGINIA PIEDMONT AND SOUTHERN MARYLAND LATER
TODAY INTO TONIGHT AS THE COLD FRONT IS EXPECTED TO STALL IN THESE
AREAS. ELSEWHERE CAN ANTICIPATE THE RAIN SHOWERS OR THUNDER ENDING
FROM WEST TO EAST DURING THE MID TO LATE MORNING HOURS IN THE WEST
AND EARLY TO MID AFTERNOON IN THE EAST.
&&
.SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/...
AMPLIFIED UPPER TROUGH WILL PROGRESS ACROSS THE ERN CONUS DURING THE
FIRST HALF OF THE WEEKEND...WITH THIS TROUGH AXIS CROSSING THE CWA
SAT NGT. BREEZY W-NW FLOW BEHIND THE DEPARTING COLD FRONT WILL BE
ACCOMPANIED BY THE ARRIVAL OF COOL CANADIAN AIR. COMBINATION OF DEEP
MIXING FROM CAA AND MID-LVL DPVA/MOISTURE WITH THE TROUGH WILL LEAD
TO INCREASING CLOUDS DURING THE DAY. SKIES MAY WIND UP BECOMING
CLOUDY ACROSS MUCH OF THE AREA DURING THE AFTN. EVEN WITH CLOUD
COVER AND CAA...MAX TEMPS WILL BE CLOSE TO NORMAL FOR THE START OF
NOVEMBER.
ONCE THE LLVL TROUGH AXIS SWINGS THRU THE MTS SAT EVE...BOUNDARY-
LAYER WINDS VEER TO NWLY AND GREAT LAKES MOISTURE ARRIVES. UPSLOPE
SHOWERS WILL LIKELY START AROUND THIS TIME. 00Z NAM/GFS BUFKIT
SOUNDINGS INDICATE THERMAL PROFILES ARE TOO WARM FOR SNOW AT THE
ONSET...THOUGH THE BOUNDARY LAYER COOLS ENOUGH FOR PRECIP TO MIX
WITH OUR CHANGE TO SNOW LATE SAT NGT AT ELEVATIONS ABOVE APPROX 2500
FT. DEPTH OF MOISTURE MAY ALSO BE TOO SHALLOW FOR ICE CRYSTALS IN
THE CLOUDS...WHICH WOULD RESULT IN JUST RAIN SHOWERS.
HIPRES BUILDS IN FROM THE GREAT LAKES ON SUN. CAA CONTINUES SUN. NW
WINDS WILL BE BREEZY AGAIN ON SUN WITH GUSTS 20-30 MPH POSSIBLE
DURING THE AFTN. MOISTURE WILL REMAIN TRAPPED UNDERNEATH THE
INVERSION ON SUN...WHICH FAVORS DEVELOPMENT OF A STRATOCU FIELD.
FCST MAX TEMPS FOR SUN ARE AROUND 10F BELOW NORMAL.
WIND FIELD BECOMES LIGHT SUN NGT WITH HIPRES NOSING SWD INTO THE
CWA. WHERE WINDS DECOUPLE...AIRMASS WILL BE ABLE TO DROP BELOW
FREEZING.
&&
.LONG TERM /MONDAY THROUGH THURSDAY/...
SFC HIPRES CENTERED OVER NEW ENGLAND MON AND THE NWRN ATLANTIC
TUE-WED IS EXPECTED TO WEDGE DOWN THE ERN SEABOARD. MEANWHILE...
RIDGE ALOFT WILL BECOME ANCHORED OVER THE SOUTHEAST COAST THRU THE
FIRST HALF OF THE WEEK. THE PROXIMITY OF THIS BLOCKING RIDGE SHOULD
KEEP THE CENTRAL CONUS STORM SYSTEM UPSTREAM OF THE REGION DURING
THIS TIME. THE NRN PERIPHERY OF THE RIDGE IS FCST TO BREAK DOWN
LATER IN THE WEEK IN RESPONSE TO THE APPROACH OF THE NRN STREAM
TROUGH. THE FIRST MENTION OF PRECIP IS WED NGT AND THU WHEN THE COLD
FROPA IS FCST TO OCCUR. THIS FAR OUT...THERE IS STILL SOME
UNCERTAINTY WITH TIMING.
&&
.AVIATION /08Z FRIDAY THROUGH TUESDAY/...
MVFR CONDITIONS EXPECTED TODAY WITH RESPECT TO GUSTY RAIN SHOWERS
MOVING ACROSS THE REGION. IFR COULD EVOLVE WITH THE HEAVIEST SHOWERS
OR ANY THUNDERSTORMS AND WOULD SEEM MORE PROBABILISTIC BETWEEN 10Z
AND 14Z. STRONG SOUTHERLY SYNOPTIC WINDS OR GUSTY WINDS IN SHOWERS
WILL GUST IN EXCESS OF 25 TO 30 KTS. LOW LEVEL WIND SHEER IS ALSO A
THREAT ESPECIALLY THIS MORNING. WINDS WILL VEER AROUND TO THE WEST
LATER TODAY AND DECREASE SOME WITH MVFR CONDITIONS BECOMING VFR BY
THIS EVENING.
VFR CONDITIONS THIS WEEKEND AND ERY NEXT WEEK. NW WINDS COULD GUSTS
15-25 KT EACH AFTN THIS WEEKEND AS HIPRES BUILDS IN FROM THE GREAT
LAKES.
&&
.MARINE...
A NWLY SURGE BEHIND THE EXITING COLD FRONT WILL REACH THE NRN AND
WRN MARINE ZONES LATE IN THE DAY SAT. ALSO...DEEPER MIXING ON LAND
WILL RESULT IN HIGHER GUSTS NEAR THE COAST. THEREFORE...ONLY ISSUED
A SCA FOR MID AND UPPER TIDAL POTOMAC RVR AND THE NRN CHSPK BAY
STARTING SAT AFTN. SCA WILL LIKELY NEED FOR PORTIONS OF THE WATERS
SAT NGT. HIPRES BUILDS IN FROM THE GREAT LAKES ON SUN. WITH A TIGHT
PRESSURE GRADIENT AND STEEP LAPSE RATES FROM CAA...ALL MARINE ZONES
WILL LIKELY NEED A SCA FOR SUN.
WINDS RELAX MON AND TUE WITH HIPRES RIDGING SWD ALONG THE ERN
SEABOARD.
&&
.TIDES/COASTAL FLOODING...
TIDAL ANOMALIES HAVE NOT RESPONDED MUCH YET TO THE STRENGTHENING SLY
FLOW OVNGT AND REMAIN ABOUT THREE-QUARTERS FOOT ABOVE ASTRONOMICAL
PREDICTION. EXPECT POSITIVE DEPARTURES TO INCREASE THIS MRNG THOUGH
AS SLY WINDS INCREASE EVEN MORE...BUT NO CONCERNS FOR COASTAL
FLOODING DURING THE NON-PREFERRED HIGH TIDE CYCLE THIS MRNG. LATEST
AVAILABLE MODEL GUIDANCE ONLY INDICATING ANNAPOLIS AT RISK FOR MINOR
COASTAL FLOOD LATE THIS AFTN-EVE...BUT CBOFS BARELY REACHES
THRESHOLD. WITH WINDS BECOMING MORE SWLY THAN S THIS AFTN AND
ASTRONOMICAL TIDES RELATIVELY LOW...HELD OFF ISSUING A COASTAL FLOOD
ADVISORY WITH CONFIDENCE TOO LOW ATTM.
BLOWOUT TIDES EXPECTED SATURDAY NIGHT AND SUNDAY IN STRONG NWLY FLOW.
