LAYER CAPE OF 1500-2000 J/KG. 500 HPA SHORTWAVE APPROACHING FROM
THE WEST SO CONVECTION WILL CONTINUE INTO THE EVENING. HEAVY RAIN
AND LOCALIZED FLOODING IS POSSIBLE WITH PRECIPITABLE WATERS UP TO
2 INCHES AND LIGHT FLOW ALOFT RESULTING IN SLOW STORM MOVEMENT.
ANOTHER SHORTWAVE PASSES TO THE NORTHWEST OVERNIGHT WITH A CHANCE
OF SHOWERS AND THUNDERSTORMS...THOUGH LESS WIDESPREAD WITH THE
LOSS OF DAYTIME HEATING. FLOW REMAINS EASTERLY AND WITH
ASTRONOMICALLY HIGH TIDES MINOR COASTAL FLOODING IS FORECAST OVER
WESTERN COASTAL AREAS. SEE COASTAL FLOODING SECTION FOR MORE INFO.
MAV/MET BLEND USED FOR TEMPS SINCE THE TWO WERE BASICALLY
IDENTICAL OVERNIGHT.

&&
.SHORT TERM /6 AM TUESDAY MORNING THROUGH WEDNESDAY NIGHT/...
A MORE POTENT 500 HPA SHORTWAVE ASSOCIATED WITH A COLD FRONT
APPROACHES DURING THE DAY TUESDAY. EAST FLOW IN THE MORNING BECOMES
MORE SOUTHERLY DURING THE DAY...AS A RESULT HIGHER INSTABILITY AND
BEST CHANCE OF CONVECTION WILL BE FROM NYC WEST. CAPE/SHEAR ARE
MODEST BUT GIVEN MOIST ENVIRONMENT...MODERATELY STRONG FORCING AND
VEERING LOW-LEVEL FLOW...COULD SEE A FEW STRONG STORMS WITH GUSTY
WINDS AND HEAVY RAIN.

GUIDANCE BY 1 FOOT TUESDAY DUE TO ITS TYPICAL HIGH BIAS IN SW FLOW.
LONG TERM...GENERALLY LOOKING AT SUB-SCA CONDITIONS WEDNESDAY
THROUGH SATURDAY...HOWEVER THERE IS A CHANCE THAT SEAS COULD REACH 5
FT ON THURSDAY AS THE GRADIENT TIGHTENS JUST A BIT AS HIGH PRESSURE
APPROACHES FROM THE WEST. THE BEST CHANCE OF ANY 5 FT SEAS
DEVELOPING WILL BE ACROSS THE FAR EASTERN WATERS...AND SHOULD NOT
LAST TOO LONG.

A COASTAL FLOOD ADVISORY REMAINS IN EFFECT FOR PORTIONS OF WESTERN
COASTLINES DUE TO ANTICIPATED MINOR COASTAL FLOODING WITH THE HIGH

NEW JERSEY ZONES AS WELL AS NORTHWESTERN SUFFOLK...SOUTHERN NEW
HAVEN AND THE TWIN FORKS WHERE DEPARTURES COULD RESULT IN MORE
