Area forecast discussion, Feb 24, 11:29 AM EST, 2 hours 12 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC
1129 AM EST THU FEB 24 2011
.SYNOPSIS...
LOW PRESSURE WILL APPROACH THE REGION TONIGHT AND THEN MOVE
ACROSS THE MID ATLANTIC ON FRIDAY. HIGH PRESSURE RETURNS FOR
SATURDAY. A WARM FRONT WILL LIFT TO THE NORTH OF THE AREA ON
SUNDAY...THEN A COMPLEX LOW PRESSURE AREA WILL IMPACT THE REGION
ON MONDAY.
&&
.NEAR TERM /THROUGH TONIGHT/...
SFC ANLYS SHOWS LOW PRES OVR N TX W/ A WARM FNT XTNDG ACROSS TN.
RAFL ASSO W/ THE FNT HAS ENTERED SW VA...AND WL BE MAKING ITS WAY
E AND N AS THE AFTN PROGRESSES. IT APPEARS THE AXIS OF HVST PCPN
WL MOVE N OF THE MASON-DIXON LN OVRNGT. TEMPS IN THE CWA WL PRBLY
CLIMB AFTR MDNGT.
DUE TO XTNSV CLD CVR HV DROPPED FCST HIGHS IN CENTRAL SHEN VLLY FM
M50S TO U40S.
PRVS DSCN...
THE HIGHEST QPF AMOUNTS TNGT ARE ACROSS THE POTOMAC HIGHLANDS AND
IN WRN MD WHERE UP TO AN INCH OF RAINFALL IS POSSIBLE. QPF AMOUNTS
DROP DOWN TO A HALF INCH OR LESS DURING THE TNGT PERIOD FROM I-95
SOUTH AND EAST.
WINDS WILL BECOME GUSTY AT HIGHER ELEVS LATE TNGT AS A 60-70 KT
SWLY LOW-LEVEL JET APPROACHES. NOCTURNAL BOUNDARY LAYER WILL LIMIT
MIXING OF THE STRONG WINDS DOWN TO THE SFC...BUT GUSTS TO 30 MPH
WILL BE POSSIBLE ACROSS THE RIDGE TOPS.
&&
.SHORT TERM /FRIDAY/...
MANY QUSTNS EXIST FOR FRI - WL RW/TRW BE OCCURRING THAT COULD
BRING STRONG WINDS DOWN TO THE SFC AHD OF THE FNT? HOW WINDY WL IT
BE IN THE HRS POST FNTL? MDLS ARE PORTRAYING A 3-6 HR PD FRI AFTN
OF HIGH WINDS BEHIND THE FNT. WE HV A HIGH WIND WTCH IN EFFECT. AS
A GNRL RULE THE ISSUANCE OF A HIGH WIND WRNG/WIND ADVSRY IS A 1ST
PD (<12 HRS) EVENT BUT CAN BE ISSUED UP TO 24 HRS IN ADVANCE IF
CONFIDENCE IS HIGH. WE'VE HAD A MRNG CONFERENCE...AND AHD OF THE
FNT...ON STRAIGHT SWRLY WINDS...REACHING THESE LVLS IS XTRMLY
DIFFICULT...ESPECIALLY IN THE WINTER. REGARDING THE RW/TRW
SCENARIO I DON'T FEEL CONFIDENT ENOUGH AT THIS TIME - I'D LK TO BE
A LTL CLOSER TO THE EVENT. POST FNTL - I'VE SEEN PLENTY OF
SITUATIONS WHERE WE THOUGHT THE STRONGEST WINDS WOULD BE
IMMEDIATELY POST FNTL AND THE STRONG PRES SURGE ENDED UP NOT
HAPPENING FOR SVRL HRS AFTR. THESE ARE ALL THINGS TO THINK
ABT...BUT IN NEXT FEW HRS I CAN'T ENVISION CHANGING THE WATCH -
ONLY THING I MIGHT CHG IS TO ADD THE COUNTIES NOT CURRENTLY IN THE
WTCH.
PRVS DSCN...
WARM FRONT WILL BE NORTH OF THE MASON DIXON LINE TO START
FRIDAY...PLACING THE CWA IN A WARM SECTOR. THIS WILL HAVE LIKELY
LIFTED THE INITIAL AREA OF HEAVY RAIN TO THE NORTH OF THE
CWA...HOWEVER ANOTHER AREA OF SHOWERS WILL BE COMING IN FROM THE
WEST CLOSER TO A COLD FRONT. AT 12Z...LOW PRESSURE IS EXPECTED TO BE
SOMEWHERE NEAR THE NORTHERN WEST VIRGINIA PANHANDLE...WITH A COLD
FRONT TRAILING SOUTH THROUGH THE APPALACHIANS. STRONG LOW LEVEL
SOUTHWESTERLY JET /70+ KNOTS AT 850 MB FROM THE NAM/GFS/ WILL BE IN
PLACE AHEAD OF THE COLD FRONT...WHICH WILL ENHANCE SHEAR ACROSS THE
REGION. IN ADDITION...IN THE WARM SECTOR...MODELS CONTINUE TO
FORECAST LOW AMOUNTS OF CAPE. THEREFORE...WILL HAVE A CHANCE OF
THUNDERSTORMS FOR AREAS EAST OF THE BLUE RIDGE THAT HAVE THE
POTENTIAL TO TRANSPORT GUSTY AND PERHAPS DAMAGING WINDS TO THE
SURFACE INTO AFTERNOON. OUTSIDE OF CONVECTION...THERE IS ALSO THE
POTENTIAL FOR STRONG WINDS TO OCCUR WITH AND BEHIND THE FRONTAL
PASSAGE. FOR THIS REASON...WILL ISSUE A HIGH WIND WATCH FOR A LARGE
PORTION OF THE CWA FOR THE POSSIBILITY OF 50 KNOT GUSTS.
&&
.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
HIGH PRESSURE BUILDS IN FROM THE WEST FRIDAY NIGHT AND SATURDAY.
WIND GUSTS WILL GRADUALLY ABATE FRIDAY NIGHT...WITH DRY CONDITIONS
THROUGH SATURDAY.
HIGH PRESSURE MOVES OFF THE COAST SATURDAY NIGHT...ALLOWING A WARM
FRONT TO MOVE NORTH THROUGH THE REGION SUNDAY. WEAK LIFT WILL
PROVIDE A SMALL CHANCE OF RAIN FOR NORTHWEST AREAS. BUT MOST PLACES
WILL REMAIN DRY UNTIL LATE SUNDAY NIGHT AND MONDAY WHEN ANOTHER AREA
OF LOW PRESSURE APPROACHES FROM THE WEST AND DRAGS A COLD FRONT
THROUGH ON MONDAY. GUSTY WINDS AND COOLER CONDITIONS WILL OCCUR IN
THE WAKE OF THE FRONT ON TUESDAY.
&&
.AVIATION /18Z THURSDAY THROUGH TUESDAY/...
ALTHO XTNSV CLD CVR TDA SKIES XPTCD TO RMN IN THE VFR CAT. LGT RA
XPCTD AT CHO/IAD/MRB BY LATE AFTN.
STRONG 925/850 MB JET FROM THE SOUTHWEST WILL BE ONGOING FRIDAY
MORNING...AND WILL PRODUCE NON-CONVECTIVE LOW LEVEL WIND SHEAR
AROUND 50 KNOTS AT 2K FT. SHOWERS WILL BE ONGOING...WITH ASSOCIATED
FLIGHT RESTRICTIONS. HAVE MEDIUM TO HIGH CONFIDENCE IN IFR
CONDITIONS TO START FRIDAY MORNING. FRONT WILL SWIFTLY MOVE THROUGH
THE REGION FROM WEST TO EAST FRIDAY AFTERNOON. THERE MAY BE RW/TRW THAT
TRANSPORT STRONG GUSTY WINDS TO THE SURFACE AT THE HUBS AS
WELL. AS THE COLD FRONT PASSES AND DIRECTLY BEHIND IT SHOWERS
WILL END AND CIGS/VSBYS WILL IMPROVE BUT A WIND SHIFT TO THE
NORTHWEST WILL OCCUR AND WINDS 40-50 KNOTS MAY MAKE IT TO THE
SURFACE. GUSTS WILL GRADUALLY ABATE IN THE EVENING.
HIGH PRESSURE BUILDS IN FOR SATURDAY...THEN MOVES EAST ON SUNDAY.
THE NEXT WEATHER MAKER WILL BRING A CHANCE OF RAIN SUNDAY NIGHT INTO
MONDAY. GUSTY WINDS LOOK TO OCCUR AGAIN TUESDAY BEHIND THIS SYSTEM.
&&
.MARINE...
THE CWF WAS RESENT TO REDUCE THE AREA THAT WAS IN A STORM WRNG FRI
AFTN TO A GALE. CONFIDENCE IS MUCH HIGHER IN THE LATTER.
REGARDLESS MARINERS SHOULD PLAN TO VACATE THE WATERS FRI AFTN. IF
CONDITION WARRANT THERE IS STILL TIME TO REISSUE THE STORM WRNG
LATER. THE GALE WAS XTND THRU TO MDNGT.
SCA IN EFFECT THIS AFTN AND EVE FOR AREAS OF THE
MAIN STEM CHSPK BAY AND LOWER TIDAL POTOMAC THAT ARE PRONE TO SLY
CHANNELING WITH GUSTS TO 20 KT EXPECTED. A STRONG SW JET JUST OFF
THE SFC WILL APPROACH LATE TNGT. SCA EXPECTED ACROSS ALL MARINE
ZONES DURING THE OVNGT/ERY MRNG HRS.
SMALL CRAFT ADVISORY WILL CONTINUE FRIDAY MORNING. STRONG LOW LEVEL
JET WILL BE IN PLACE...BUT THE BRUNT OF THE SOUTHWEST WINDS WILL
HAVE A HARD TIME MAKING IT TO THE SURFACE. HOWEVER...SHOWERS AND
POSSIBLY A THUNDERSTORM MAY CONVECTIVELY TRANSPORT GUSTY WINDS LATER
IN THE MORNING/AFTERNOON AND THEN A COLD FRONT PASSES BY AND EXPECT
STRONG WINDS TO BETTER MIX DOWN.
HIGH PRESSURE BUILDS IN SATURDAY FOR LESS WIND...THEN MOVES OFF
THE COAST SUNDAY. NEXT FRONT MOVES THROUGH MONDAY...WITH GUSTY
WINDS BEHIND IT FOR TUESDAY.
&&
.HYDROLOGY...
AXIS OF HEAVIEST RAINFALL TOTALS IS FORECAST TO RESIDE JUST
NORTHWEST OF THE LWX HSA. LATEST TOTAL QPF INCLUDING TONIGHT AND
FRIDAY SUGGESTS AROUND 1 INCH OF RAIN ACROSS THE METRO AREAS...WITH
MORE TO THE WEST AND PERHAPS UP TO 1.5 INCHES OVER THE HIGHLANDS.
OBVIOUSLY...ANY CONVECTION COULD BRING DOWN LOCALLY HIGHER AMOUNTS
AND THIS COULD RESULT IN MINOR PROBLEMS. BUT ON THE
WHOLE...WIDESPREAD FLOODING IS NOT EXPECTED. DUE TO RECENT DRY
WEATHER...STREAMS WERE RUNNING LOWER THAN NORMAL.
