AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC
804 PM EDT MON APR 9 2012

.SYNOPSIS...
A COLD FRONT WILL PASS THROUGH THE REGION THIS EVENING. NORTHWEST
FLOW AROUND AN UPPER LOW WILL PROVIDE A PERIOD OF SEASONABLY
COOL CONDITIONS FOR THE MID-ATLANTIC REGION TUESDAY THROUGH
THURSDAY. HIGH PRESSURE WILL BUILD OVERHEAD LATE IN THE WEEK...
BEFORE MOVING OFF THE EAST COAST THIS WEEKEND.

&&

.NEAR TERM /THROUGH TUESDAY/...
HEADLINE UPDATE...CANCELLED THE GALE WRNG AND RED FLAG WRNG. SCA
IN EFFECT FOR THE WATERS OVER THE NEXT FEW HRS. WILL SEND ANOTHER
UPDATE SHORTLY FOR THE NEW RED FLAG WRNG FOR TUE...

FROM PREV DISC...
NORTHWEST WINDS HAVE GUSTED TO 35 KTS AT DULLES AIRPORT AND 35
KTS AT WASHINGTON REGAN AIRPORT. KLWX RADAR SHOWS SOME INSTABILITY
SHOWERS ALONG THE BLUE RIDGE BUT NONE OF THE RAIN APPEARS TO BE
REACHING THE GROUND. CLOUDS WILL INCREASE OVER THE AREA TONIGHT
AHEAD OF THE BOUNDARY AS IT SAGS SOUTH. W-NW WINDS OF 15 TO 30 MPH
WILL CONTINUE...WITH GUSTS UP TO 35 MPH. LIGHT SHOWERS MAY DEVELOP
LATER THIS EVENING BUT LITTLE RAIN IS EXPECTED. 'INVERTED V' TYPE
FORECAST SOUNDINGS INDICATE THE EVAPORATIVE COOLING FROM THE
PRECIPITATION ALOFT MAY JUST SERVE TO INCREASE THE WIND SPEEDS.
ADDITIONALLY DOWNSLOPING WINDS ARE POSSIBLE OFF THE BLUE RIDGE IN
THE SHENANDOAH VALLEY AND ALLEGANY FRONT.

WINDS WILL TAPER OFF THIS LATER THIS EVENING AND TONIGHT.
TEMPERATURES WILL FALL BACK TO NEAR 40 DEGREES OVERNIGHT IN THE
BALTIMORE / DC METRO AREAS. WINDS WILL KEEP BLOWING NEAR THE
WESTERN RIDGETOPS BUT THE SHENANDOAH VALLEY AND OTHER VALLEYS TO
THE LEE OF THE MOUNTAINS WILL DROP BELOW FREEZING AGAIN TONIGHT. A
FREEZE WARNING HAS BEEN ISSUED FOR THESE AREAS. BEHIND THE FRONT A
COOL NORTH TO NORTHWEST FLOW WILL PROVIDE MORE GUSTY WINDS AND A
SLIGHT CHANCE OF SHOWERS TUESDAY.

&&

.SHORT TERM /TUESDAY NIGHT THROUGH WEDNESDAY NIGHT/...
THE UPPER LOW OVER SERN CANADA WILL WEAKEN TUE NGT AND WED.
SHORTWAVE ENERGY ROTATING AROUND THE BACKSIDE OF THE LOW WILL MOVE
ACROSS THE MID-ATLANTIC STATES LATE TUE NGT INTO WED. ENHANCED
W-NW FLOW AROUND THIS FEATURE AND BEHIND A SFC COLD FRONT WILL
REINFORCE THE COLDER AIR THRU THE PERIOD.

A FREEZE WATCH HAS BEEN ISSUED FOR THE POTOMAC HIGHLANDS AND CENTRAL
SHENANDOAH VLY FOR LATE TUE NGT. EAST OF THE WATCH...5-10 MPH WINDS
SUSTAINED THRUOUT THE NGT WILL LIKELY PREVENT FROST FORMATION AND
TEMPS FROM REACHING THE FREEZING MARK.

LIFT AHEAD OF THE SHORTWAVE TROUGH...STEEPENING LLVL LAPSE RATES AND
UPSLOPE FLOW WILL SUPPORT SHOWERS ALONG THE WRN SLOPES OF THE
ALLEGHENY FRONT. FCST THERMAL PROFILES ARE EXPECTED TO BE COLD
ENOUGH FOR PRECIP TO BE SNOW ALONG THE RIDGE TOPS LATE TUE NGT
INTO WED. ACCUMULATIONS SHOULD BE LIGHT. WITH LIFT FROM THE TROUGH
AND STEEP LAPSE RATES IN THE LOWEST 10 KFT...A FEW STREAMERS FROM
THE GREAT LAKES MAY MAKE IT INTO THE NORTHERN AND WESTERN SUBURBS OF
DC AND BALTIMORE DURING THE DAY WED.

THE THREAT OF A FREEZE WILL CONTINUE INTO WED NGT FOR AREAS WEST OF
THE BLUE RIDGE.

&&

.LONG TERM /THURSDAY THROUGH MONDAY/...
THE UPPER TROUGH WILL PROGRESS OFF THE NEW ENGLAND COAST THU. NW
FLOW AROUND THE LOW WILL CONTINUE THE PERIOD OF BELOW NORMAL
TEMPERATURES THRU THU NGT. THU NGT IS THE LAST NGT WE HAVE
FREEZE CONCERNS FOR THE AREAS WEST OF THE BLUE RIDGE. FROST
ADVISORIES MAY BE NEEDED FOR THE N/W SUBURBS THU NGT UNDER A GOOD
SETUP FOR RADIATIONAL COOLING.

HIPRES OVER THE REGION WILL START TO SHIFT EWD OFF THE COAST BY LATE
FRI WHILE AN UPPER RIDGE BUILDS OVER THE ERN CONUS. SWLY RETURN
FLOW AROUND THE HIGH WILL ADVECT WARMER AIR INTO THE MID-ATLANTIC
REGION. MAX TEMPS FRI WILL BE NEAR NORMAL...POSSIBLY A FEW DEGREES
ABOVE NORMAL IF THE HIGH MOVES OFF THE COAST QUICKER THAN FCST.
ENSUING WAA PATTERN WILL CONTINUE INTO THE WEEKEND. MAX TEMPS
AROUND 70F SAT MAY FLIRT WITH 80F SUN.

A COLD FRONT WILL TRY TO APPROACH FROM THE NW SUN INTO MON...BUT MAY
HAVE A HARD TIME PROGRESSING DOWNSTREAM INTO THE BLOCKING RIDGE.
TIMING OF FROPA IS UNCERTAIN AT THIS TIME...BUT THE FRONT WILL BE
ACCOMPANIED BY CHANCES FOR SHOWERS AND STORMS.

&&

.AVIATION /00Z TUESDAY THROUGH SATURDAY/...
VFR BKN-OVC100 WITH ISOLD -SHRA AFT 22Z. SFC WNDS 29015G30KT WILL
ALSO DECREASE AFTER 22Z. IN THE VICINITY OF SHOWERS ISOLD G35KT
POSSIBLE WITH ERRATIC WIND DIRECTIONS UNTIL 22Z. WINDS TAPER OFF AFT
22Z AS VFR CONTINUES...AND VFR SKC-SCT200 EXPECTED OVERNIGHT. LLWS
POSSIBLE TONIGHT WITH 35KTS WIND 1000 FT AGL. GUSTY NW WINDS
POSSIBLE AGAIN TUESDAY WITH VFR CONDITIONS.

VFR CONDITIONS THRU THE REMAINDER OF THE WEEK. BREEZY NW WINDS
AROUND 15 KT COULD GUST 20-25 KT WED. WINDS WILL BE MUCH LIGHTER
TOWARD THE END OF THE WEEK AS HIPRES SETTLES OVER THE REGION.

&&

.MARINE...
SEE HEADLINE UPDATE AT THE TOP... SOME BATCHES OF LIGHT SHOWERS
NOT MAKING TO THE SFC OVER THE WATERS...BUT ARE PUSHING THE
GUSTIER WINDS NEAR AND ABOVE GALE CRITERIA. A FEW ISOLATED SHOWERS
MAY ALSO AFFECT THE BAY/TP LATER THIS EVENING AS A COLD FRONT
APPROACHES AND MOVES THRU DURING. NW FLOW PICKS UP AGAIN TUE. SCA
HAS BEEN ISSUED FOR ALL OF THE WATERS ON TUE.

SCA HAS BEEN EXTENDED INTO TUE NGT FOR MOST OF THE MD CHSPK BAY.
NW WINDS WILL GUST 15-20 KT DURING THIS TIME. A COLD FRONT WILL
MOVE THRU THE WATERS ERY WED. BEHIND THE FRONT...SCA CONDITIONS
ARE EXPECTED FOR ALL MARINE ZONES DURING THE DAY WED. SCA HAZARD
MAY CONTINUE FOR PORTIONS OF THE WATERS WED NGT INTO THU. WINDS
BEGIN TO DIMINISH THU NGT AND FRI AS HIPRES MOVES OVERHEAD.

&&

.FIRE WEATHER...
WE RECEIVED NEARLY A HALF DOZEN REPORTS OF BRUSH FIRES ACROSS THE
CWA YESTERDAY. 3.9 MICRON SATELLITE IMAGERY SHOWS TWO CONTINUED
INTO THE LATE MORNING...ONE NEAR THE SHENANDOAH/HARDY COUNTY LINE
AND ONE NEAR PAGE/ROCKINGHAM COUNTY. HUMIDITY HAS CREPT UP TOWARD
30 PERCENT LATE THIS AFTERNOON BUT WITH THE DRY FUELS IN PLACE OUR
RED FLAG WARNING WILL CONTINUE UNTIL 8 PM. ADDITIONAL WIND ISSUES
ARE POSSIBLE WITH A COLD FRONT THAT COULD ENHANCE GUSTY /
DOWNSLOPING WINDS...ESPECIALLY TO THE LEE OF THE BLUE RIDGE.

10-HR FUEL MOISTURE MAY RECOVER A LITTLE TONIGHT AND TUESDAY
MORNING...BUT BREEZY CONDITIONS ARE EXPECTED WITH FREQUENT WIND
GUSTS AROUND 20 TO 25 MPH AGAIN TUESDAY. DESPITE COOLER
TEMPERATURES...THERE WILL BE ENOUGH DRY AIR ADVECTION FROM THE
NORTHWEST FLOW FOR THE RELATIVE HUMIDITY TO DROP TO NEAR 30
PERCENT ACROSS MOST LOCATIONS AGAIN TOMORROW. A FIRE WEATHER WATCH
HAS BEEN ISSUED FOR TUESDAY. THE EVENT HAS BEEN WELL ADVERTISED
AND WILL WAIT FOR THE FIRST WARNING TO EXPIRE BEFORE MAKING A
DECISION ABOUT TOMORROW. OUR PARTNER AGENCIES SEEM TO BE IN FAVOR
OF ISSUING ANOTHER RED FLAG TOMORROW...ESPECIALLY IN VIRGINIA.
MARYLAND HAS BEEN QUIETER TODAY.

BREEZY CONDITIONS ARE EXPECTED TO CONTINUE WEDNESDAY...BUT COOLER
TEMPERATURES MAY KEEP THE RELATIVE HUMIDITY A BIT HIGHER COMPARED
TO RECENT DAYS.
