AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEWPORT/MOREHEAD CITY NC
105 PM EST WED MAR 3 1999

THINGS GETTING BUSY HERE...SO WILL ISSUE DISCUSSION A BIT EARLY.
WILL NEED TO KEEP A MENTION OF EVENING SHOWERS/TSTMS PERIOD TO
ACCOUNT FOR ANY LEFTOVER CONVECTION OVER EXTREME ERN NC.
OTHERWISE...COLDFRONT WILL MOVE THRU THE AREA OVERNIGHT WITH HI PRES
BECOMING RE-ESTABLISHED. NGM HANGS ONTO SOME WRAP-AROUND MOISTURE
OVERNIGHT...ESPECIALLY THE NRN SECTIONS...WHILE THE ETA DRIES THINGS
OUT NICELY. GIVEN THE EXTENT OF UPSTREAM CLOUDINESS ON VIS
SATPIX...MIGHT WANT TO HANG ONTO MORE CLOUDINESS OVER OUR NRN ZONES.

FOR TEMPS...ETA-BASED LCL SCHEME MUCH COOLER TONIGHT THAN NGM MOS...WHICH
MAKES SENSE GIVEN THAT NGM HOLDS ONTO MORE MOISTURE OVERNIGHT. WILL
SPLIT THE DIFFERENCE FOR THE MINS. REMAINING MAX/MIN TEMPS ARE
FAIRLY CLOSE TO LCL SCHEME AND WILL STAY CLOSE.

FOR THE COASTAL SECTIONS...BOUNDARY LAYER WIND FIELDS...ESPECIALLY
FROM THE ETA/NGM HAVE BEEN OVERDONE OF LATE. WILL MAINTAIN CURRENT
FCST OF STRONG SMALL CRAFT ADVISORY TONIGHT WITH VEERING AND
DIMINISHING WINDS/SEAS BY THURS AFTERNOON.
