AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC
219 PM EDT WED SEP 17 2014

.SYNOPSIS...
HIGH PRESSURE WILL BUILD TOWARD THE EAST COAST THROUGH TONIGHT. A
WEAK COLD FRONT WILL PASS THROUGH THE AREA THURSDAY AND HIGH
PRESSURE WILL RETURN FOR FRIDAY AND SATURDAY. ANOTHER COLD FRONT
WILL PASS THROUGH THE AREA SUNDAY NIGHT INTO MONDAY.

&&

.NEAR TERM /THROUGH THURSDAY/...
HIGH PRESSURE WILL CONTINUE TO BRING DRY AND SEASONABLE CONDITIONS
TO THE AREA LATE THIS AFTERNOON. THE HIGH WILL SLOWLY BUILD EAST
TOWARD THE COAST TONIGHT WHILE A WEAK COLD FRONT APPROACHES FROM
THE OHIO VALLEY AND WESTERN PENNSYLVANIA. A LIGHT SOUTHERLY FLOW
AND SOME MORE CLOUD COVER WILL ALLOW MILDER CONDITIONS COMPARED TO
TUESDAY NIGHT. MIN TEMPS WILL RANGE FROM THE MID TO UPPER 40S
ALONG THE ALLEGHENY HIGHLANDS TO NEAR 60 IN WASHINGTON AND
BALTIMORE.

A WEAK COLD FRONT WILL PASS THROUGH THE REGION THURSDAY. THERE
WILL BE SOME INSTABILITY DUE TO A SOUTHERLY FLOW AHEAD OF THE
BOUNDARY...BUT FORCING AND MOISTURE WILL BE LIMITED. A COUPLE
SHOWERS ARE POSSIBLE...BUT PRECIPITATION AMOUNTS WILL BE LIGHT AND
MOST AREAS WILL END UP DRY. MAX TEMPS WILL RANGE FROM THE 60S IN
THE MOUNTAINS TO THE MIDDLE 70S NEAR WASHINGTON AND BALTIMORE.

&&

.SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY/...
THE COLD FRONT WILL DROP TO OUR SOUTH THURSDAY NIGHT BEFORE
STALLING OUT OVER THE SOUTHEASTERN CONUS FRIDAY THROUGH SATURDAY.
HIGH PRESSURE WILL BUILD INTO NEW ENGLAND THURSDAY NIGHT THROUGH
FRIDAY BEFORE MOVING OFF THE COAST SATURDAY. THE SURFACE RIDGE
AXIS WILL REMAIN OVER THE REGION DURING THIS TIME.

THE RIDGE AXIS SHOULD REMAIN CLOSE ENOUGH TO BRING DRY CONDITIONS
TO THE AREA DURING THIS TIME BUT CLOUDS MAY HANG AROUND DUE TO AN
ONSHORE COMPONENT TO THE LOW-LEVEL FLOW...ESPECIALLY ACROSS THE
SHENANDOAH VALLEY INTO THE POTOMAC HIGHLANDS. AN EAST TO NORTHEAST
FLOW FRIDAY WILL CAUSE MAX TEMPS TO BE BELOW CLIMO...BUT WINDS
SHOULD TURN TOWARD THE SOUTHEAST SATURDAY ALLOWING FOR WARMER
CONDITIONS.

&&

.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
HIGH PRESSURE WILL REMAIN WEDGED SOUTHWARD BETWEEN THE APPALACHIAN
MOUNTAINS AND EAST COAST SATURDAY NIGHT...KEEPING DRY CONDITIONS IN
THE REGION.

A COLD FRONT WILL MOVE FROM THE EASTERN GREAT LAKES TO THE EAST
COAST SUNDAY AND SUNDAY NIGHT. THERE IS A CHANCE FOR SHOWERS ALONG
THE FRONT WEST OF THE BLUE RIDGE SUNDAY AND IN ALL AREAS SUNDAY
NIGHT. UPPER LEVEL SUPPORT SHOULD PIVOT NORTHEAST INTO EASTERN
CANADA BY SUNDAY NIGHT...THE FRONT COULD STALL ACROSS THE DELMARVA
PENINSULA AND TIDEWATER OF VIRGINIA BRIEFLY.

A REINFORCING PUSH OF UPPER LEVEL ENERGY MONDAY SHOULD PUSH THE
FRONT OFFSHORE BY LATE MONDAY. HIGH PRESSURE WILL GRADUALLY BUILD
INTO THE REGION MONDAY NIGHT THROUGH WEDNESDAY TO ALLOW FOR THE NEXT
PUSH OF COLDER AIR.

&&

.AVIATION /18Z WEDNESDAY THROUGH MONDAY/...
A WEAK COLD FRONT WILL APPROACH THE TERMINALS TONIGHT BEFORE
PASSING THROUGH THURSDAY. VFR CONDITIONS AND LIGHT WINDS ARE
EXPECTED MOST OF THE TIME...BUT PATCHY BR IS POSSIBLE LATE TONIGHT
INTO EARLY THURSDAY AND A STRAY SHOWER CANNOT BE RULED OUT
THURSDAY AFTERNOON.

HIGH PRESSURE WILL RETURN FOR FRIDAY AND SATURDAY...BRINGING MORE
VFR CONDITIONS. VFR CONDITIONS SATURDAY NIGHT THROUGH SUNDAY WITH
LIGHT AND VARIABLE WINDS.

&&

.MARINE...
HIGH PRESSURE WILL SLOWLY BUILD TOWARD THE COAST TONIGHT AND A
WEAK COLD FRONT WILL PASS THROUGH THE WATERS THURSDAY. AN ISOLATED
SHOWER IS POSSIBLE THURSDAY AFTERNOON. HIGH PRESSURE WILL BUILD
TOWARD THE WATERS THURSDAY NIGHT AND FRIDAY. A PRESSURE SURGE WILL
CAUSE NORTH-NORTHEAST WINDS TO INCREASE. A SMALL CRAFT ADVISORY IS
IN EFFECT FOR THE MARYLAND CHESAPEAKE BAY AND LOWER TIDAL POTOMAC
RIVER LATE THURSDAY NIGHT THROUGH FRIDAY MORNING.

THE FLOW WILL TURN TOWARD THE SOUTHEAST LATER FRIDAY THROUGH
SATURDAY. WINDS MAY BE CLOSE TO SCA CRITERIA AT TIMES...BUT GUSTS
HAVE BEEN CAPPED AT 15 KNOTS FOR NOW SINCE THE GRADIENT IS
EXPECTED TO WEAKEN A BIT.

NO MARINE HAZARDS SATURDAY NIGHT. SMALL CRAFT ADVISORIES ARE
POSSIBLE SUNDAY WITH AN AREA OF LOW PRESSURE NEAR THE TIDEWATER OF
VIRGINIA AND THE MAIN STEM CHESAPEAKE BAY.

&&

.TIDES/COASTAL FLOODING...
HIGH PRESSURE WILL CONTINUE TO BUILD TOWARD THE COAST TONIGHT. THE
FLOW WILL TURN TOWARD THE SOUTHEAST DURING THIS TIME...CAUSING
TIDAL ANOMALIES TO INCREASE. TIDAL ANOMALIES UP TO A FOOT ABOVE
NORMAL ARE EXPECTED TONIGHT AND THIS WILL CAUSE MINOR TIDAL
FLOODING FOR SENSITIVE AREAS NEAR HIGH TIDE. A COASTAL FLOOD
ADVISORY IS IN EFFECT TONIGHT FOR THE MARYLAND CHESAPEAKE BAY
FROM ANNE ARUNDEL COUNTY THROUGH ST MARYS COUNTY.
ELSEWHERE...MINOR FLOODING IS POSSIBLE WITH THE HIGH TIDE CYCLE
LATE TONIGHT INTO EARLY THURSDAY BUT A COASTAL FLOOD ADVISORY HAS
NOT BEEN ISSUED AT THIS TIME DUE TO SLIGHTLY HIGHER THRESHOLDS.

A WEAK COLD FRONT WILL PASS THROUGH THE WATERS THURSDAY AND HIGH
PRESSURE WILL BUILD OVER NEW ENGLAND BEHIND THIS FRONT. AN
EASTERLY COMPONENT TO THE WIND IS EXPECTED TO CONTINUE DURING THIS
TIME AND IT WILL LIKELY LAST THROUGH THE WEEKEND.
THEREFORE...MINOR TIDAL FLOODING IS POSSIBLE NEAR TIMES OF HIGH
TIDE THROUGH THE WEEKEND. THE BEST CHANCE FOR MINOR TIDAL FLOODING
WILL BE DURING THE LATE EVENING AND MORNING HIGH TIDE CYCLE WHICH
IS THE HIGHER OF THE TWO.

&&

.LWX WATCHES/WARNINGS/ADVISORIES...
DC...NONE.
MD...COASTAL FLOOD ADVISORY FROM 9 PM THIS EVENING TO 4 AM EDT
     THURSDAY FOR MDZ014-017-018.

OVER CNTRL VA HAD SOME LIGHT SHOWERS ALONG IT EARLIER THIS EVE.
FAIR WX STRATUS CLOUD BATCHES HAVE BEEN COMMON ACROSS OUR REGION
DURING THE SECOND HALF OF THE DAY...WHICH ARE NOW DISSIPATING AND
WILL GIVE US A MAINLY CLEAR OVERNIGHT PERIOD.

THE ERN HALF OF THE CONUS IS ESSENTIALLY UNDER THIS LARGE UPPER

.SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/...
A WEAK COLD FRONT WILL PASS THROUGH THE REGION WEDNESDAY NIGHT

A COLD FRONT WILL MOVE FROM THE EASTERN GREAT LAKES TO THE EAST
COAST SUNDAY AND SUNDAY NIGHT. THERE IS A CHANCE FOR SHOWERS AND A
FEW THUNDERSTORMS AHEAD OF AND ALONG THE FRONT WEST OF THE BLUE

.NEAR TERM /THROUGH WEDNESDAY/...
THE MOST PRONOUNCED KINK IN THE UPPER LEVEL FLOW OF A LARGER-SCALE
UPPER TROUGH HAS BEEN WELL TO OUR SOUTH OVER THE PAST FEW HRS...
CLOSER TO THE VA/NC BORDER. THE FEATURE HAS HELPED DEVELOP SOME
CONVECTION ACROSS THE CAROLINAS...AND EVEN A WEAK FRONTAL BOUNDARY
OVER CNTRL VA HAD SOME LIGHT SHOWERS ALONG IT EARLIER THIS EVE.
FAIR WX STRATUS CLOUD BATCHES HAVE BEEN COMMON ACROSS OUR REGION
DURING THE SECOND HALF OF THE DAY...WHICH ARE NOW DISSIPATING AND
WILL GIVE US A MAINLY CLEAR OVERNIGHT PERIOD.

THE ERN HALF OF THE CONUS IS ESSENTIALLY UNDER THIS LARGE UPPER
TROUGH THAT HAS BEEN SPILLING COLD/COOL AND DRY CANADIAN AIR DOWN
INTO THE NRN HALF OF THE US FOR THE PAST COUPLE OF DAYS. THE MID-
ATLC IS NOW NEARLY ON THE BACK SIDE OF THE TROUGH AXIS...W/ HIGH
PRESSURE BUILDING IN AT THE SFC FROM THE UPPER MIDWEST. THIS WILL
CONTINUE OUR QUIET/TRANQUIL CONDITIONS THRU THE REMAINDER OF THE
WORK WEEK.

PREV DISC...
MIN TEMPS WILL RANGE FROM THE UPPER 30S OVER THE ALLEGHENY
HIGHLANDS WHERE RADIATIONAL COOLING IS EXPECTED...TO THE UPPER 50S
AND LOWER 60S IN DOWNTOWN WASHINGTON AND BALTIMORE. PATCHY FOG IS
EXPECTED OVERNIGHT...BUT IT WILL NOT BE WIDESPREAD DUE TO THE DRY
ADVECTION CURRENTLY IN PLACE.

WEDNESDAY...
HIGH PRESSURE WILL GRADUALLY SHIFT TOWARD THE COAST BUT MORE DRY
CONDITIONS ARE EXPECTED WITH MAX TEMPS SLIGHTLY BELOW CLIMO...
RANGING FROM THE 60S IN THE POTOMAC HIGHLANDS TO THE MIDDLE 70S
NEAR WASHINGTON AND BALTIMORE. A SCT-BKN CU DECK WILL DEVELOP
DURING THE LATE MORNING AND AFTERNOON HOURS...BUT CLOUDS MAY BE
MORE WIDESPREAD ACROSS PORTIONS OF CENTRAL VIRGINIA AND SOUTHERN
MARYLAND WHERE OVERRUNNING WILL CONTINUE WELL BEHIND A COLD FRONT
OVER THE SOUTHEASTERN CONUS.

&&

.SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/...
A WEAK COLD FRONT WILL PASS THROUGH THE REGION WEDNESDAY NIGHT
INTO THURSDAY. LITTLE MOISTURE OR FORCING WILL BE ASSOCIATED WITH
THE FRONT SO IT WILL HAVE LITTLE TO NO IMPACT AS IT MOVES THROUGH.
A STRAY SHOWER CANNOT BE RULED OUT...BUT ANY SHOWER COVERAGE WILL
BE QUITE LIMITED SO THE FORECAST REMAINS DRY FOR NOW. HIGH
PRESSURE WILL BUILD IN BEHIND THE FRONT FOR THURSDAY NIGHT AND
FRIDAY...BRINGING DRY CONDITIONS AND BELOW NORMAL TEMPERATURES.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
HIGH PRESSURE OVER NEW ENGLAND WILL WEDGE ITSELF SOUTHWARD BETWEEN
THE APPALACHIAN MOUNTAINS AND EAST COAST FRIDAY NIGHT THROUGH
SATURDAY NIGHT...KEEPING DRY CONDITIONS IN THE REGION.

A COLD FRONT WILL MOVE FROM THE EASTERN GREAT LAKES TO THE EAST
COAST SUNDAY AND SUNDAY NIGHT. THERE IS A CHANCE FOR SHOWERS AND A
FEW THUNDERSTORMS AHEAD OF AND ALONG THE FRONT WEST OF THE BLUE
RIDGE SUNDAY AND IN ALL AREAS SUNDAY NIGHT. BECAUSE THE INITIAL PUSH
OF UPPER LEVEL SUPPORT LOOKS TO PIVOT NORTHEAST INTO EASTERN CANADA
BY SUNDAY NIGHT...THE FRONT COULD STALL ACROSS THE DELMARVA
PENINSULA AND TIDEWATER OF VIRGINIA BRIEFLY.

A REINFORCING PUSH OF UPPER LEVEL ENERGY MONDAY SHOULD PUSH THE
FRONT OFFSHORE BY LATE MONDAY. HIGH PRESSURE WILL GRADUALLY BUILD
INTO THE REGION MONDAY NIGHT AND TUESDAY TO ALLOW FOR THE NEXT PUSH
OF COLDER AIR TO ARRIVE IN TIME FOR MIDWEEK ACTIVITIES.

&&

.AVIATION /01Z WEDNESDAY THROUGH SUNDAY/...
HIGH PRESSURE WILL REMAIN OVER THE TERMINALS THROUGH WEDNESDAY.
PATCHY BR MAY BRIEFLY REDUCE VSBYS LATE TONIGHT INTO EARLY
WEDNESDAY...ESPECIALLY ACROSS KCHO AND KMRB.

A WEAK COLD FRONT WILL PASS THROUGH THE TERMINALS WEDNESDAY NIGHT
INTO THURSDAY BEFORE HIGH PRESSURE RETURNS FOR LATER THURSDAY
THROUGH FRIDAY. VFR CONDITIONS ARE EXPECTED MOST OF THE TIME...BUT
PATCHY BR MAY BRIEFLY REDUCE VSBYS DURING THE LATE NIGHT AND EARLY
MORNING HOURS.

VFR CONDITIONS FRIDAY NIGHT THROUGH SATURDAY WITH LIGHT AND
VARIABLE WINDS AS HIGH PRESSURE HUGS THE EASTERN SEABOARD.

WINDS DIMINISH TONIGHT AS HIGH PRESSURE BUILDS OVER THE WATERS.
HOWEVER...GUSTS AROUND 15 KNOTS ARE EXPECTED ALONG THE MARYLAND
CHESAPEAKE BAY AND LOWER TIDAL POTOMAC RIVER AS NORTHERLY WINDS
CHANNEL.

HIGH PRESSURE WILL SLOWLY DRIFT EAST WEDNESDAY BEFORE A COLD FRONT
MOVES THROUGH LATE WEDNESDAY NIGHT INTO THURSDAY. THE GRADIENT

211 PM EDT TUE SEP 16 2014

.SYNOPSIS...
HIGH PRESSURE WILL BUILD OVER THE REGION THROUGH WEDNESDAY. A WEAK
COLD FRONT WILL PASS THROUGH THE AREA LATE WEDNESDAY NIGHT INTO
THURSDAY. HIGH PRESSURE WILL RETURN FOR FRIDAY AND SATURDAY BEFORE
MOVING OFF THE COAST SUNDAY.

&&

.NEAR TERM /THROUGH WEDNESDAY/...
HIGH PRESSURE BEHIND A COLD FRONT WILL CONTINUE TO BUILD TOWARD
THE REGION LATE THIS AFTERNOON. A NORTHWEST FLOW AHEAD OF IT WILL
ALLOW FOR DRY AND SEASONABLY MILD CONDITIONS ALONG WITH LOW
HUMIDITY. A SCT TO BKN CU DECK IS EXPECTED DEVELOP DUE TO THE
COLD ADVECTION.

THE HIGH WILL BUILD OVER THE REGION TONIGHT...BRINGING MORE DRY
CONDITIONS. THERE MAY BE SOME CLOUDS HUNG UP OVER CENTRAL VIRGINIA
AND SOUTHERN MARYLAND DUE TO OVERRUNNING WELL BEHIND A COLD FRONT
OVER THE SOUTHEASTERN CONUS. MIN TEMPS WILL RANGE FROM THE UPPER
30S OVER THE ALLEGHENY HIGHLANDS WHERE RADIATIONAL COOLING IS
EXPECTED...TO THE UPPER 50S AND LOWER 60S IN DOWNTOWN WASHINGTON
AND BALTIMORE. PATCHY FOG IS EXPECTED OVERNIGHT...BUT IT WILL NOT
BE WIDESPREAD DUE TO THE DRY ADVECTION CURRENTLY IN PLACE.

HIGH PRESSURE WILL GRADUALLY SHIFT TOWARD THE COAST
WEDNESDAY...BUT MORE DRY CONDITIONS ARE EXPECTED WITH MAX TEMPS
SLIGHTLY BELOW CLIMO...RANGING FROM THE 60S IN THE POTOMAC
HIGHLANDS TO THE MIDDLE 70S NEAR WASHINGTON AND BALTIMORE. A SCT-
BKN CU DECK WILL DEVELOP DURING THE LATE MORNING AND AFTERNOON
HOURS...BUT CLOUDS MAY BE MORE WIDESPREAD ACROSS PORTIONS OF
CENTRAL VIRGINIA AND SOUTHERN MARYLAND WHERE OVERRUNNING WILL
CONTINUE WELL BEHIND A COLD FRONT OVER THE SOUTHEASTERN CONUS.

&&

.SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/...
A WEAK COLD FRONT WILL PASS THROUGH THE REGION WEDNESDAY NIGHT
INTO THURSDAY. LITTLE MOISTURE OR FORCING WILL BE ASSOCIATED WITH
THE FRONT SO IT WILL HAVE LITTLE TO NO IMPACT AS IT MOVES THROUGH.
A STRAY SHOWER CANNOT BE RULED OUT...BUT ANY SHOWER COVERAGE WILL
BE QUITE LIMITED SO THE FORECAST REMAINS DRY FOR NOW. HIGH
PRESSURE WILL BUILD IN BEHIND THE FRONT FOR THURSDAY NIGHT AND
FRIDAY...BRINGING DRY CONDITIONS AND BELOW NORMAL TEMPERATURES.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
HIGH PRESSURE OVER NEW ENGLAND WILL WEDGE ITSELF SOUTHWARD BETWEEN
THE APPALACHIAN MOUNTAINS AND EAST COAST FRIDAY NIGHT THROUGH
SATURDAY NIGHT...KEEPING DRY CONDITIONS IN THE REGION.

A COLD FRONT WILL MOVE FROM THE EASTERN GREAT LAKES TO THE EAST
COAST SUNDAY AND SUNDAY NIGHT. THERE IS A CHANCE FOR SHOWERS AND A
FEW THUNDERSTORMS AHEAD OF AND ALONG THE FRONT WEST OF THE BLUE
RIDGE SUNDAY AND IN ALL AREAS SUNDAY NIGHT. BECAUSE THE INITIAL PUSH
OF UPPER LEVEL SUPPORT LOOKS TO PIVOT NORTHEAST INTO EASTERN CANADA
BY SUNDAY NIGHT...THE FRONT COULD STALL ACROSS THE DELMARVA
PENINSULA AND TIDEWATER OF VIRGINIA BRIEFLY.

A REINFORCING PUSH OF UPPER LEVEL ENERGY MONDAY SHOULD PUSH THE
FRONT OFFSHORE BY LATE MONDAY. HIGH PRESSURE WILL GRADUALLY BUILD
INTO THE REGION MONDAY NIGHT AND TUESDAY TO ALLOW FOR THE NEXT PUSH
OF COLDER AIR TO ARRIVE IN TIME FOR MIDWEEK ACTIVITIES.

&&

.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
HIGH PRESSURE WILL REMAIN OVER THE TERMINALS THROUGH WEDNESDAY.
PATCHY BR MAY BRIEFLY REDUCE VSBYS LATE TONIGHT INTO EARLY
WEDNESDAY...ESPECIALLY ACROSS KCHO AND KMRB.

A WEAK COLD FRONT WILL PASS THROUGH THE TERMINALS WEDNESDAY NIGHT
INTO THURSDAY BEFORE HIGH PRESSURE RETURNS FOR LATER THURSDAY
THROUGH FRIDAY. VFR CONDITIONS ARE EXPECTED MOST OF THE TIME...BUT
PATCHY BR MAY BRIEFLY REDUCE VSBYS DURING THE LATE NIGHT AND EARLY
MORNING HOURS.

VFR CONDITIONS FRIDAY NIGHT THROUGH SATURDAY WITH LIGHT AND
VARIABLE WINDS AS HIGH PRESSURE HUGS THE EASTERN SEABOARD.

&&

.MARINE...
HIGH PRESSURE WILL CONTINUE TO BUILD TOWARD THE WATERS THIS
AFTERNOON. A SMALL CRAFT ADVISORY REMAINS IN EFFECT FOR THE WATERS
UNTIL 5 PM...BUT IT WILL BE MARGINAL WITH WIND GUSTS NEAR 20
KNOTS. WINDS WILL DIMINISH TONIGHT AS HIGH PRESSURE BUILDS OVER
THE WATERS. HOWEVER...GUSTS AROUND 15 KNOTS ARE EXPECTED ALONG THE
MARYLAND CHESAPEAKE BAY AND LOWER TIDAL POTOMAC RIVER AS NORTHERLY
WINDS CHANNEL.

HIGH PRESSURE WILL SLOWLY DRIFT EAST WEDNESDAY BEFORE A COLD FRONT
MOVES THROUGH LATE WEDNESDAY NIGHT INTO THURSDAY. THE GRADIENT
SHOULD BE WEAK ENOUGH DURING THIS TIME FOR NO MARINE HEADLINES.
HOWEVER...A PRESSURE SURGE AHEAD OF BUILDING HIGH PRESSURE MAY
CAUSE WIND TO GUST PAST SCA CRITERIA FOR PORTIONS OF THE WATERS
THURSDAY NIGHT INTO FRIDAY. HIGH PRESSURE WILL BUILD OVERHEAD FOR
THE WEEKEND.

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC
931 PM EDT MON SEP 15 2014

.SYNOPSIS...
A COLD FRONT WILL PASS THROUGH THE REGION OVERNIGHT. HIGH PRESSURE WILL
RETURN FOR TUESDAY THROUGH WEDNESDAY BEFORE A REINFORCING COLD
FRONT MOVES THROUGH THURSDAY. HIGH PRESSURE WILL BUILD OVERHEAD
LATE IN THE WEEK.

&&

.NEAR TERM /THROUGH TUESDAY/...
CLOUD COVER WILL CONTINUE TO INCREASE OVERNIGHT AS AN UPPER
DISTURBANCE AND COLD FRONT APPROACH FROM THE WEST.
A FEW SHOWERS CANNOT BE RULED OUT AS THIS SYSTEM MOVES THROUGH.
HOWEVER...THE DYNAMICS WITH THIS SYSTEM WILL REMAIN MOSTLY TO OUR
NORTH AND THE DEEPER MOISTURE WILL BE OFF TO OUR SOUTH.
THEREFORE...ANY SHOWERS THAT DO OCCUR WILL BE LIMITED IN COVERAGE
AND BRIEF. BEST CHANCES APPEAR TO BE OVER THE POTOMAC HIGHLANDS
AND EAST OF THE BLUE RIDGE...ESPECIALLY THE BALTIMORE METRO AREA.

THE COLD FRONT WILL MOVE OFF TO OUR EAST TUESDAY AND A NORTHWEST
FLOW IS EXPECTED AHEAD OF HIGH PRESSURE BUILDING IN FROM THE
MIDWEST. MAX TEMPS MAY ACTUALLY BE A FEW DEGREES WARMER THAN TODAY
DUE TO A DEEP MIXING LAYER AND INCREASING AMOUNTS OF SUNSHINE
BEHIND THE BOUNDARY. MAX TEMPS ARE FORECAST TO REACH THE MID TO
UPPER 70S ACROSS MOST LOCATIONS...BUT COOLER IN THE MOUNTAINS.

&&

.SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/...
HIGH PRESSURE WILL BUILD OVER NEW ENGLAND TUESDAY NIGHT THROUGH
WEDNESDAY BEFORE A REINFORCING COLD FRONT PASSES THROUGH THE AREA
LATE WEDNESDAY NIGHT INTO THURSDAY.

THE HIGH SHOULD BE CLOSE ENOUGH TUESDAY NIGHT AND WEDNESDAY TO
KEEP DRY CONDITIONS IN PLACE...DESPITE AN UPPER-LEVEL TROUGH
OVERHEAD. TEMPS WILL BE A FEW DEGREES BELOW CLIMO DURING THIS TIME
DUE TO THE UPPER-LEVEL TROUGH.

THE REINFORCING COLD FRONT LATE WEDNESDAY NIGHT INTO THURSDAY WILL
BE WEAK AND LITTLE MOISTURE WILL BE ASSOCIATED WITH IT. A STRAY
SHOWER CANNOT BE RULED OUT...BUT A DRY FORECAST CONTINUES FOR NOW
SINCE COVERAGE WOULD BE LIMITED AT BEST.

&&

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
A PIECE OF ENERGY WILL TRY TO PUSH ACROSS THE REGION THURSDAY
NIGHT BUT BECAUSE OF THE LACK OF MOISTURE...WE HAVE POPS
GENERALLY LESS THAN 10 PERCENT.

HIGH PRESSURE WILL BUILD INTO THE REGION FROM THE GREAT LAKES
AREA LATE THURSDAY NIGHT THROUGH SATURDAY...KEEPING DRY
CONDITIONS IN THE REGION.

A COLD FRONT WILL APPROACH THE REGION SUNDAY AND SUNDAY
NIGHT...BRINGING A SLIGHT CHANCE OF SHOWERS AND PERHAPS A
THUNDERSTORM OR TWO.

THE MAIN UPPER LEVEL TROUGH OF LOW PRESSURE WILL MOVE THROUGH
THE REGION MONDAY...KEEPING A SLIGHT CHANCE OF SHOWERS IN THE
PICTURE DURING THIS PERIOD.

&&

.AVIATION /02Z TUESDAY THROUGH SATURDAY/...
A COLD FRONT WILL PASS THROUGH THE TERMINALS OVERNIGHT. A COUPLE
SHOWERS CANNOT BE RULED OUT...BUT MOST AREAS WILL BE DRY. FOG IS
POSSIBLE LATE TONIGHT INTO EARLY TUESDAY...BUT THE CLOUD COVER
FROM THE COLD FRONT SHOULD KEEP IT LIMITED.

HIGH PRESSURE WILL BRING MORE VFR CONDITIONS TUESDAY THROUGH
TUESDAY EVENING. PATCHY BR IS POSSIBLE OVERNIGHT TUESDAY INTO
EARLY WEDNESDAY. A COLD FRONT WILL PASS THROUGH THE TERMINALS LATE
WEDNESDAY NIGHT INTO THURSDAY...BUT THE BOUNDARY WILL BE WEAK SO
IT WILL HAVE A LIMITED IMPACT ON THE TERMINALS. HIGH PRESSURE WILL
RETURN FOR FRIDAY AND SATURDAY.

&&

.MARINE...
A COLD FRONT WILL PASS THROUGH THE WATERS OVERNIGHT. A SMALL
CRAFT ADVISORY IS IN EFFECT FOR THE WATERS BEHIND THE FRONT
TUESDAY...BUT IT WILL BE MARGINAL WITH NORTH-NORTHWEST WIND GUSTS
NEAR 20 KNOTS.

HIGH PRESSURE WILL BUILD OVER THE WATERS TUESDAY NIGHT THROUGH
WEDNESDAY BEFORE A REINFORCING COLD FRONT PASSES THROUGH LATE
WEDNESDAY NIGHT INTO THURSDAY. HIGH PRESSURE WILL RETURN FOR LATE
IN THE WEEK.

&&

.TIDES/COASTAL FLOODING...
SOUTHERLY WINDS WILL CAUSE ANOMALIES TO INCREASE TO NEAR ONE FOOT
ABOVE NORMAL. A COASTAL FLOOD ADVISORY IS IN EFFECT TONIGHT FROM
ANNE ARUNDEL TO ST MARYS COUNTIES ALONG THE WESTERN SHORE OF THE
CHESAPEAKE BAY...PRIMARILY FOR SENSATIVE AREAS.

&&
