AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC
330 PM EST SAT FEB 19 2011

.SYNOPSIS...
HIGH PRESSURE WILL CONTINUE TO BUILD INTO THE MID ATLANTIC THROUGH
SUNDAY MORNING. A TROUGH OF LOW PRESSURE WILL MOVE INTO THE EASTERN
STATES MONDAY...BRINGING WELCOME RAIN SHOWERS...BEFORE CHANGING TO A
WINTRY MONDAY NIGHT. HIGH PRESSURE THEN THROUGH MID WEEK BEFORE THE
NEXT TROUGH MOVES IN FROM THE WEST LATE IN THE WEEK.
&&

.NEAR TERM /THROUGH SUNDAY/...
WNDY DAY CONTS ACRS CWFA. REF PNSLWX FOR LTST SUMMARY OF HIGH WND
GUSTS ACRS CWFA. NMRS REPORTS HV EXCEEDED 50 MPH...AND QUITE A FEW
HV REACHED WRNG CRIT OF 57 MPH. NOT ONLY ARE CONDS ONGOING ACRS
AREA...BUT H9-8 WNDS STRENGTHENING. A NEW CORE OF 70 KT AT H8 PER
NAM WL BE PIVOTING ACRS ERN CWFA 21Z-03Z. H9 INCR FM 50 TO 55 KT...
WHICH LINGERS THRU THE NGT. GFS/RUC SIMLR...ALTHO THE GFS IS THE
WEAKER OF THE 3. GRANTED VERT MOMENTUM TRANSFER WL BECOME LESS FVRBL
DUE TO BOTH DIURNAL TRENDS AND BLDG SFC HIPRES...TAKING SOME OF THE
STING OUT OF THE SITUATION...BUT THINK THAT AT LEAST BRZY CONDS WL
DOMINATE THE ERN SXN OF CWFA WELL INTO THE NGT. HWW CONTS AREAWIDE
THRU 9PM. THAT MAY NEED TO BE ADDRESSED...BY AT LEAST ADDING A WND
ADVY IF NOT AN XTNDD WRNG FOR SOME CNTYS. WL LET EVE FCSTRS HNDL
THAT AS THE TIME COMES. EVEN THO SKC...THE MIXING PROVIDED BY THE
WND WL INHIBIT RAPIDLY DROPPING TEMPS. MIN-T ON THE WARM SIDE OF MOS
ENVELOPE.

HIPRES OHD BY ELY TMRW...AND THEN THE RDG AXIS SHIFTS EWD TMRW AFTN
PERMITTING WAA/RTN FLOW. BEST ISENT LIFT SEEMS TO BE DLAD COMPARED
TO PRVS CYCLES...WHICH SEEMS REASONABLE FOR SYSTEM EVOLUTION. HV
INCRSD CLDS THRU THE DAY COINCIDENT W/ WAA BUT BACKED OFF ON POPS...
PRESERVING ONLY SCHC W OF SHEN RVR. WENT MIDPACK FOR MAXT. IF WE CAN
SEE A LTL MORE INSOLATION...THAT MAY END UP BEING ON THE COOL SIDE
ACRS CENTRL VA.
&&

.SHORT TERM /SUNDAY NIGHT THROUGH MONDAY NIGHT/...
SUNDAY NIGHT THROUGH MONDAY...LARGE SCALE RIDGING OVER THE ERN CONUS
WILL FLATTEN AS A LOW OVER SKIRTS EAST FROM THE CENTRAL PLAINS
TO ACROSS THE MID ATLANTIC AND ANOTHER A LOW DESCENDS FROM HUDSON
BAY TO NEW ENGLAND. SFC HIGH PRESSURE WILL BE SHUNTED TO EAST OF FL
SUNDAY NIGHT...ALLOWING QUITE A FETCH OF GULF MOISTURE TO STREAM
TOWARD THE MID ATLANTIC /AIDED BY THE LOW EXITING THE CENTRAL
PLAINS/. QUITE AN AIRMASS BOUNDARY WILL SETUP ACROSS THE OHIO VALLEY
AS SUBTROPICAL AIR FROM THE GOM MEETS SUB ARCTIC AIR FROM CANADA
ACROSS THE MIDWEST EAST TO THE NRN MID ATLANTIC THROUGH THIS PERIOD.
MOST OF THE ACTIVITY ASSOCIATED WITH THIS CONVERGENCE WILL BE
NORTH/WEST OF THE CWA...THOUGH FOR SUNDAY NIGHT LIKELIES WERE ADDED
TO THE FAR NW /INVOF KCBE/ AND CHANCES WERE EXPANDED SOUTH TO
INCLUDE BALT-WASH AS THE GREAT PLAINS LOW SKIRTS EAST. DOWNSLOPING
WLY FLOW...SOURCED FROM THE GULF WILL ALLOW FOR AN ABNORMALLY WARM
DAY ON MONDAY...MAX TEMPS INTO THE 70S FOR SOUTHERN PORTIONS OF THE
VALLEYS WEST OF THE BLUE RIDGE...AND THE VA PIEDMONT...MID 60S AT
LEAST FOR THE BALT-WASH METRO. QUESTIONS FOR TEMPS ON MONDAY IS
TIMING OF LOW PASSAGE TO THE NORTH AND AMOUNT OF CLOUDS DURING THE
DAY.

MONDAY NIGHT...THE LOW DESCENDING FROM HUDSON BAY WILL MOVE SOUTH
ACROSS NEW ENGLAND AND PHASE WITH THE LOW/WAVE THAT CAME FROM THE
CENTRAL PLAINS. THIS WILL DRAW COLD AIR /-5 TO -10C H85 TEMPS/ DOWN
ACROSS THE MID ATLANTIC. CONTINUED GULF MOISTURE CONVERGENCE WITH
THE TROUGH AXIS WILL PROVIDE BANDS OF RAIN TO DEVELOP ALONG THE
FRONT. AS THE FRONT SAGS SOUTH...RAPID COLUMN COOLING SHOULD ALLOW
FOR A CHANGEOVER TO A WINTRY MIX...THEN SNOW AROUND MIDNIGHT BEFORE
THE BOUNDARY/END OF PRECIP MOVES SOUTH BY EARLY TUESDAY. WITH GROUND
TEMPERATURES WARMING FROM RECENT ABOVE NORMAL AIR TEMPERATURES...ANY
SNOW LATE MONDAY NIGHT...SHOULD END UP BEING SLUSHY ON THE
GROUND...THOUGH MIN TEMPS IN THE MID 20S ARE EXPECTED NORTH.
NEVERTHELESS...THE STRONG BAROCLINIC ZONE...AS INDICATED BY ALL
GUIDANCE...SUGGESTS MESOSCALE FORCING TO PLAY AN IMPORTANT ROLE IN
PRECIP MONDAY NIGHT. AMPLE MOISTURE AND GOOD LIFT SHOULD ALLOW FOR
SOME LOCALLY HEAVY PRECIP RATES. NO SLEET OR FREEZING RAIN IN THE
GRIDS YET SINCE THE CHANGEOVER TO SNOW SHOULD BE QUICK. PLEASE
CONTINUE TO PAY ATTENTION TO THIS MONDAY NIGHT SCENARIO OVER THE
WEEKEND.
&&

.LONG TERM /TUESDAY THROUGH SATURDAY/...
TUESDAY THROUGH THURSDAY...HIGH PRESSURE MOVES SOUTH ACROSS THE
REGION AGAIN. ANY SNOW MID TUESDAY MORNING SHOULD END RAPIDLY WITH
THE BOUNDARY PUSHING SOUTH. BELOW NORMAL TEMPS TUESDAY...THEN RETURN
FLOW BRING TEMPS BACK TO NORMAL /MID 40S MAX TEMPS/ FOR
WEDNESDAY...THEN ABOVE FOR THURSDAY.

THE NEXT UPPER TROUGH MOVES EAST INTO THE ERN CONUS FRIDAY IN A
SCENARIO SIMILAR TO EARLIER IN THE WEEK. 12Z GUIDANCE TODAY SUGGESTS
RAIN FRIDAY...AND WITH A TRACK FARTHER NORTH...SNOW IS LESS LIKELY
AT THIS TIME. HOWEVER...STAY TUNED TO THAT SCENARIO AS WELL.
&&

.AVIATION /21Z SATURDAY THROUGH THURSDAY/...
POTENTIAL FOR 50 KT GUSTS CONT THRU 02Z ON GUSTY NW FLOW. AFTR 02Z
SFC WNDS WL DIMINISH BUT WNDS THRU ABT 5K FT WL INCR. THAT MAY LEAD
TO ANTHR LLWS SITUATION. TAFS DO NOT REFLECT THAT ATTM. WL NEED TO
CONSIDER AND POTENTIALLY ADDRESS THAT SHORTLY. CLDS/VSBYS WL NOT BE
FACTOR THRU VALID PD. KEEPING GUSTY WNDS THRU THE NGT-- AT LEAST 35
KT THRU 10Z...25 KT THRU 15Z-- AND THEN WNDS BLO 10 KT THRU THE DAY
TMRW.

LOW PRESSURE APPROACHES FROM THE WEST SUNDAY NIGHT...INCREASING SLY
FLOW TO 15 TO 20 KT LATE WITH MID LEVEL /VFR/ CIGS. A COLD FRONT
MOVES THROUGH MONDAY MORNING...BRINGING WLY FLOW OF AROUND 20 KT
WITH GUSTS TO 30 KT THROUGH THE DAY. CHANCES FOR RAIN SHOWERS
INCREASE THROUGH MONDAY. HEAVIER RAIN/IFR POSSIBLE MONDAY NIGHT AS
ANOTHER COLD FRONT MOVES SOUTH ACROSS THE AREA. A CHANGEOVER TO TO
SNOW IS EXPECTED MONDAY NIGHT BEFORE ENDING TUESDAY MORNING. NLY
FLOW 10 TO 15 KT WITH GUSTS TO 20 KT TUESDAY. HIGH PRESSURE/DRY
TUESDAY THROUGH THURSDAY.
&&

.MARINE...
OCNL GUSTS 45-48 KT SUPPORT SR.W ON THE WATERS ATTM. HV NOT CHGD
THAT HAZARD...KEEPING IT IN EFFECT THRU 9PM. HV MADE A FEW CHGS
THRAFTR TO STREAMLINE HEADLINES AS HIPRES BLDS...KEEPING GLW THRUT
THE NGT AND SCA FOR SVRL HRS TMRW. KEPT SCA LONGER FOR THE MD
BAY/TRIBS INCL LWR PTMC SVRL HRS LONGER DUE TO BETTER FETCH. WNDS
MIGHT DROP SOONER THAN CERTAIN HEADLINES SUGGEST...SPCLY THE
GLW...BUT AGN ATTEMPTED TO SIMPLIFY PROCESS.

LOW PRESSURE APPROACHES FROM THE WEST SUNDAY NIGHT...INCREASING SLY
FLOW TO 15 TO 20 KT WITH GUSTS TO 25 KT AFTER MIDNIGHT...A SMALL
CRAFT ADVISORY WILL BE NEEDED SUNDAY NIGHT THROUGH TUESDAY. A COLD
FRONT MOVES THROUGH MONDAY MORNING...BRINGING WLY FLOW OF AROUND 20
KT WITH GUSTS TO 30 KT THROUGH THE DAY...BRIEF GALES POSSIBLE.
ANOTHER COLD FRONT MOVES SOUTH ACROSS THE AREA MONDAY NIGHT WITH NLY
FLOW 15 TO 20 KT WITH GUSTS TO 25 KT TUESDAY. SMALL CRAFT ADVISORY
MAY NEED TO CONTINUE INTO TUESDAY NIGHT. HIGH PRESSURE/TRANQUIL
WEDNESDAY... WITH SLY FLOW THURSDAY AND FRIDAY AHEAD OF THE NEXT
SYSTEM.

.FIRE WEATHER...
INTENSE DRY GUSTY WINDS AND LOW FUEL MOISTURE HAVE CREATED AN
ENHANCED FIRE THREAT. RED FLAG CRITERIA SOLIDLY BEING MET ACROSS
MUCH OF THE AREA...W/ WIND GUSTS AVERAGING 35-45 KT BUT OCNLY UP TO
50-60 KT. RH VALUES IN THE TEENS AND 20S...BUT AS LOW AS SINGLE
DIGITS IN CENTRL VA.

NMRS HOT SPOTS EVIDENT ON 3.9U STLT...AND STREAMERS SEEN ON LWX
