313 PM EDT MON APR 28 2008
.SYNOPSIS...
A COLD FRONT WILL MOVE OFF THE ATLANTIC COAST OVERNIGHT. AN UPPER

&&
.NEAR TERM /TONIGHT/...
CONVECTIVE LINE HAS DEVELOPED ACROSS I-95 AS ADVERTISED...PUSHING
20-30KT GUSTS OUT AHEAD OF THE LINE AND WORKING IT/S WAY E/WRD
ACROSS THE VA PORTION OF I-95 AND LOWER SRN MD. SHOULD BE MOVING
ACROSS THE BAY THRU THE LATE AFTN HRS. HELICITY VALUES STILL
CONCERNING...W/ STRONG LOW LEVEL CONVERGENCE AND DIRECTIONAL SHEAR
IN THE LOWEST 1KM. THE LOCALIZED STRENGTH OF THE CONVERGENCE THO
WILL ONLY BE FAVORABLE FOR VERY SHORT LIVED SPIN-UPS IN THE LINE
AS IT MOVES E/WRD.
SFC ANALYSIS LOWS SEVERAL SFC LOW PRESSURE AREAS ACROSS THE ERN
SEABOARD AS THE INITIAL UPPER TROF AXIS DEAMPLIFIES AND IS ABSORBED
NE/WRD INTO THE APPROACHING/DEEPENING UPPER TROF BACK TO THE WEST.
THE SFC BRNDY WHICH IS JUST WEST OF I-95...TRACKING INTO THE REGION
AND DRYING OUT AREAS TO THE WEST FAIRLY QUICKLY. THE SUBSIDENCE
BEHIND THE FRONT WILL CONT TO DRY OUT THE MID ATLNC THRU THE EARLY
EVNG HRS...W/ THE FRONT SLIDING OFF THE COAST BY LATE TONIGHT.
OVERNIGHT...WINDS WILL BEGIN TO INCR OUT OF THE NW AND THE OVC LOW
CLOUDS WILL CONT TO SCATTER W/ LITTLE MORE THAN A FEW MID DECKS
STREAMING ACROSS THE REGION...AHEAD OF THE STRONG UPPER TROF AXIS.
&&
.SHORT TERM /TUESDAY AND TUESDAY NIGHT/...
COLD FRONT WILL HAVE MOVED OFF THE EASTERN SEABOARD BY TUESDAY
MORNING. HIGH PRESSURE WILL BEGIN TO BUILD IN FROM THE WEST.
HOWEVER...THE MAIN 500MB TROUGH AXIS WILL SWING THROUGH THE CWFA
DURING THE DAY...ACCOMPANIED BY STRONG SHORTWAVE ENERGY.
THE SURFACE WILL BE QUITE STABLE...HOWEVER MID LEVEL LAPSE RATES
WILL STEEPEN CONSIDERABLY AS THE TROUGH MOVES OVERHEAD. HAVE KEPT
THE MENTION OF SCATTERED/CHANCE OF SHOWERS IN THE GRIDS. THE CHANCE
OF PRECIPITATION WILL WANE IN THE AFTERNOON AS THE STRONG MID LEVEL
FORCING MOVES OFFSHORE.
EXPECTING A GOOD CU FIELD DURING THE DAY TOMORROW AS THE UPPER
SYSTEM MOVES THROUGH. HOWEVER...SKIES SHOULD BEGIN TO CLEAR SOMETIME
BEFORE MIDNIGHT. TOMORROW NIGHT STILL LOOKS BE BE ABOUT 7 TO 10
DEGREES BELOW NORMAL FOR LOW TEMPERATURES. THE POTENTIAL FOR FROST
STILL EXISTS FOR AREAS WEST OF THE INTERSTATE 95 CORRIDOR.
HOWEVER...AN INCREASE IN CLOUDINESS COULD IMPEDE THE DEVELOPMENT OF
FROST. WILL CONTINUE TO MENTION IN THE HWO.
&&
.LONG TERM /WEDNESDAY THROUGH MONDAY/...
THE REMAINDER OF THE WEEK IS EXPECTED TO BE QUIET...WITH THE NEXT
FRONTAL BOUNDARY TO ARRIVE DURING THE WEEKEND.

ABOVE 3 KFT. VFR CIGS/VSBYS ARE ANTICIPATED FOR THE REMAINDER OF THE
WEEK.

.MARINE...
THE IMMEDIATE CONCERN IS THE SQUALL LINE OF BRIEF INTENSE TSTM
ACTIVITY MOVING ACROSS LOWER SRN MD...REACHING THE CNTRL/SRN BAY BY
4-6PM...ALSO THE CROSSING TIME. GUSTY WINDS AND PSBLE WATERSPOUTS AS
THE LINE CROSSES. PLENTY OF LOW LEVEL SPIN IN THE ATMOS TO ALLOW
PORTIONS OF THIS LINE TO DEVELOP BRIEF WALL CLOUDS AND PSBLE
TORNADIC ACTIVITY. SCA ALSO IN EFFECT UNTIL LATE TONIGHT...SO
MARINERS SHOULD REMAIN ON LAND AS THIS LINE PROGRESSES.
OVERNIGHT...THE LOW PRESSURE SYSTEM WILL SLIDE OFF THE ATLNC COAST
W/ LIGHT WINDS RETURNING...UNTIL TUES MRNG.
LEFT THE SCA HEADLINE INTACT FOR TUESDAY. NORTHERLY SURGE BEHIND THE
FRONT HAS THE POTENTIAL TO PRODUCE WIND GUSTS OVER 18 KT. HIGH
PRESSURE WILL BUILD OVERHEAD DURING THE NIGHTTIME...SO SHOULD NOT
HAVE TO EXTEND THE HEADLINE ANY FURTHER.
