AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC
930 PM EDT FRI APR 4 2014
.SYNOPSIS...
A STATIONARY FRONT OVER THE VIRGINIA PORTION OF THE CHESAPEAKE
BAY WILL DRIFT NORTH THIS EVENING AS A WARM FRONT. A COLD FRONT
WILL MOVE EAST ACROSS THE REGION TONIGHT WITH HIGH PRESSURE THEN
BUILDING THROUGH SATURDAY NIGHT. A LOW PRESSURE SYSTEM WILL AFFECT
THE AREA MONDAY WITH A COLD FRONTAL PASSAGE LATE MONDAY NIGHT INTO
TUESDAY. HIGH PRESSURE WILL BUILD TO THE SOUTH TUESDAY NIGHT
THROUGH THURSDAY WITH THE NEXT A COLD FRONT APPROACHING BY THE END
OF NEXT WEEK.
&&
.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...
AS OF 01Z...FRONT IS EITHER STATIONARY OR HAS RETROGRADED SOUTH IN
RECENT HOURS. THIS MAY LIFT NORTH THROUGH MIDNIGHT...BUT THE COLD
FRONT WILL OVERTAKE THE COLD AIR DAMMING SOON. THE COLD FRONT HAS
PUSHED THROUGH CLARKSBURG WV WITH WEST GUSTS OF 38 KT. OUR WIND
ADVISORY CRITERIA IS 40 KT...BUT WITH THE LOW LIFTING NORTH FROM
GEORGIAN BAY...THE GRADIENT IS EXPECTED TO BE INSUFFICIENT FOR
WIND HEADLINES TONIGHT (EVEN FOR THE RIDGES). DEWPOINTS BACK OVER OHIO
ARE IN THE MID 30S...SO TEMPERATURES WILL DROP ENOUGH FOR SOME
SNOW FLAKES OUT THERE LATE TONIGHT. HOWEVER...ONLY A DUSTING ACCUM
(GENERALLY LESS THAN TWO TENTHS) IS EXPECTED OVERNIGHT (AFTER ALL
THE TEMPERATURE IS STILL 52F AT 2800 FT IN OAKLAND, MD).
THE COLD FRONT WILL CROSS THE CWA NOW THROUGH ABOUT 06Z WITH BALT-
WASH AREA GUSTS LIMITED TO AROUND 20 MPH DUE TO LOWER TEMPERATURES
FROM ONSHORE FLOW. HOWEVER...PLACES LIKE LURAY THAT ARE STILL 70F
SHOULD SEE GUSTS AROUND 30 MPH.
LOWS RANGING FM THE MU30S IN THE HIGHLANDS TO MID 40S FOR MOST OF
THE AREA EAST OF THE BLUE RIDGE.
&&
.SHORT TERM /6 AM SATURDAY MORNING THROUGH 6 PM SATURDAY/...
HIGH PRES BUILDS INTO THE AREA CREATING PLSNT WX TO START THE
WKND. TOO BAD DC CHERRY BLOSSOMS AREN'T ON TAP TO OPEN THIS WKND -
W/ SO MUCH COLD WX THESE PAST FEW MONTHS THESE ARE STILL LISTED AT
STAGE 3 OF 6 IN THE BLOOM PROCESS...WHICH IS SLOWER THAN THE
LATEST PEAK LOOM LISTED ON THE NPS PAGE - APR 9 IN 2005. BUT THE
FESTIVAL ISN'T UNTIL NEXT WKND SO HOPEFULLY THINGS WL WORK OUT.
HIGHS ARE XPCTD TO BE IN THE LM60S. NW WINDS 15-20 MPH.
.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...
AFTER A WINDY SATURDAY...WINDS WILL DROP OFF QUICKLY INTO THE EVE
HRS - AS WILL TEMPS. THE RELATIVELY LOW DEWPOINTS WILL ALLOW TEMPS
TO DROP DOWN INTO THE 30S FOR OVERNIGHT LOWS...SUBFREEZING VALUES
ACROSS THE MASON-DIXON LINE AND THE APLCNS. A SFC HIGH WILL MAKE ITS
WAY OVER THE AREA THRU THE DAY ON SUN. THE CENTER WILL TRACK OVER
THE NRN PORTIONS OF THE REGION...KEEPING A COOL NLY COMPONENT TO THE
SFC FLOW AND KEEPING OUR TEMPS MODERATED IN THE 50S THROUGHOUT THE
DAY.
ANOTHER LOW PRESSURE SYSTEM WILL DEVELOP QUICKLY LATE SUN INTO MON
OVER THE TX GULF COAST REGION/LOWER MS VLY...AS AN UPPER TROUGH
DIVES DOWN ACROSS THE SRN ROCKIES. THE TROUGH WILL PICK UP THE
SYSTEM AND MOVE IT DIRECTLY NE AND OVER THE APLCNS. PRECIP WILL
SPREAD QUICKLY UP EITHER SIDE OF THE MTN RANGE...SPREADING THE
HEAVIER BATCHES UP THE ERN SEABOARD AND OTHER LOCALIZED BATCHES OVER
THE UPPER MIDWEST DURING THE DAY ON MON.
THE SYSTEM WILL BECOME MORE COMPLEX AS A SECONDARY LOW DEVELOPS
ROUGHLY JUST SOUTH OF THE CWA AND FROM THE LEE OF THE APLCNS. THE
TRACK OF THE LOW WILL DETERMINE WHERE THE HEAVIER BATCHES OF PRECIP
PROPAGATE AND HOW THE UNSTABLE THE ATMOS WILL BE AHEAD OF THE
PASSAGE. ATTM...GUIDANCE MOST GUIDANCE MEMBERS STILL BISECTING THE
AREA FROM SW-TO-NE WHICH IS LARGELY INCONSEQUENTIAL FOR OUR
IMMEDIATE AREA IN TERMS OF CONVECTION. A GENERAL 0.5-1.0" OF RAIN
COULD COME OUT OF THE SYSTEM FOR OUR AREA W/ LOCALLY HIGHER AMOUNTS.
ONLY LIMITED INSTABILITY W/ THE SYSTEM'S PASSAGE BUT PLENTY OF LOW
LEVEL SHEAR...AS THERE TYPICALLY IS W/ AN EARLY SPRING SYSTEM AND
ONE W/ THIS TYPE OF TRACK.
MONDAY NIGHT THROUGH FRIDAY/...
INTENSIFYING LOW PRESSURE WILL MOVE NORTH UP THE WESTERN SLOPES
OF THE APPALACHIANS AND INTO THE EASTERN GREAT LAKES REGION MONDAY
NIGHT. ASSOCIATED PRECIPITATION WILL LIKELY END FROM SOUTHWEST TO
NORTHEAST DURING THE EVENING. MARGINALLY COLD AIR ON THE BACKSIDE
OF THE DEPARTING LOW COULD CAUSE A MIX WITH SNOW SHOWERS OVER THE
RIDGETOPS ALONG THE ALLEGHENY FRONT AFTER MIDNIGHT.
THE UPPER-LEVEL TROUGH AXIS WILL PIVOT ACROSS THE REGION
TUESDAY...WITH UPSLOPE RAIN SHOWERS POSSIBLE DURING THE DAY AS THE
BOUNDARY LAYER WARMS...POSSIBLY MIXING WITH SNOW AGAIN TUESDAY
EVENING BEFORE ENDING OVERNIGHT. ELSEWHERE...A GENERAL WEST TO
NORTHWEST FLOW IS EXPECTED WITH PASSING CLOUDS DURING THE AFTERNOON.
TEMPERATURES WILL DROP TO SEVERAL DEGREES BELOW NORMAL LEVELS
TUESDAY NIGHT THROUGH WEDNESDAY NIGHT AS COOL HIGH PRESSURE
APPROACHES FROM THE WEST. THIS HIGH WILL MOVE OFF THE MID-ATLANTIC
COAST LATER IN THE WEEK SETTING UP A MODERATING SOUTHWESTERLY RETURN
FLOW WITH WARMER TEMPERATURES EXPECTED. A COLD FRONT WILL APPROACH
FROM THE NORTH FRIDAY AFTERNOON BUT AT THIS TIME DOES NOT APPEAR TO
HAVE MUCH IN THE WAY OF MOISTURE TO WORK WITH.
&&
.LONG TERM /SATURDAY NIGHT THROUGH FRIDAY/...
&&
.AVIATION /01Z SATURDAY THROUGH WEDNESDAY/...
MVFR/IFR CIGS IN NERN MD/BALTIMORE RAISE TO VFR ONCE SHOWERS TO
THE WEST COME THROUGH. VFR CONDS XPCTD OVRNGT AND SAT W/ NW WINDS
GUSTING AROUND 25 KTS.
HIGH PRESSURE OVR THE AREA SUN...DROPPING OFF WINDS FOR ABOUT A
DAY...THEN PUSHES OFF THE COAST - JUST AHEAD OF ANOTHER LOW PRES
SYSTEM. THE NEXT STORM SYSTEM WILL MOVE THRU ALL-DAY MON...W/ RAIN
STARTING IN THE MRNG AND LINGERING THRU LATE EVE. A COLD FRONT
WILL SWING ACROSS THE REGION LATE IN THE DAY...W/ SOME GUSTY
CONDITIONS ALONG AND E OF THE I-95 CORRIDOR - NEAR WHERE THE SFC
LOW IS EXPECTED TO TRACK.
SUB-VFR CIGS/VSBYS LIKELY MON NIGHT IN RAIN...ESPECIALLY IN THE
EVENING. SOUTHERLY WINDS 10 TO 15 KNOTS IN THE EVENING BECOME
WESTERLY OVERNIGHT AROUND 10 KNOTS. VFR CONDS AND WESTERLY TO
NORTHWESTERLY WINDS ARE EXPECTED TUESDAY.

.MARINE...
ONSHORE FLOW WILL BECOME WLY THEN NWLY AND GUSTY LATE TONIGHT
THROUGH SATURDAY. 25 KT GUSTS COMMON ON THE WATERS DURING DAYLIGHT
SATURDAY. SCA MAY NEED TO START EARLY...BUT FOR NOW 6AM SEEMS
FINE.
LIGHT WINDS ON SUN AS HIGH PRESSURE MOVES DIRECTLY OVER THE REGION
W/ A RETURN ONSHORE FLOW BUILDING OVER THE CHES BAY DURING THE
FIRST-HALF OF THE DAY ON MON. THIS MARINE FLOW WILL LIKELY STAY IN
PLACE UNTIL A COLD FRONT PUSHES THRU THE AREA LATE MON EVE...QUICKLY
TURNING SFC WINDS BACK TO WLY AND PERIODICALLY W/IN SCA RANGE.
SCA CONDITIONS ARE POSSIBLE MONDAY EVENING IN SOUTHERLY FLOW
AHEAD OF LOW PRESSURE. GUSTY WESTERLY FLOW BEHIND LOW PRESSURE
WILL LIKELY EXCEED SCA CONDITIONS TUESDAY. SUB-SCA CONDITIONS ARE
LIKELY IN HIGH PRESSURE MID-WEEK. SCA CONDITIONS POSSIBLE AGAIN
LATE IN THE WEEK AHEAD OF AN APPROACHING COLD FRONT.
