AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSONVILLE FL
833 PM EST SUN MAR 1 2015

.UPDATE...

HIGH PRESSURE NOW JUST NORTH OF THE AREA WILL CONTINUE TO SETTLE
SOUTH INTO OUR REGION OVERNIGHT. THE ASSOCIATED WEDGE ALONG THE
COAST CURRENTLY SEPARATES MILD AIR (60S & 70S) IN THE VICINITY OF
THE I-75 CORRIDOR FROM MUCH COOLER AIR (LOW 50S) ALONG THE
ATLANTIC COAST. THE COASTAL TROUGH HAS WEAKENED AND PUSHED WELL
OFFSHORE. A MUCH WEAKER PRESSURE GRADIENT CONTINUES TO ALLOW FOR
WINDS TO DIMINISH WITH ONLY LIGHT WINDS EXPECTED TO CONTINUE
OVERNIGHT. MOIST COOL AIRMASS WILL BE FAVORABLE FOR AREAS OF FOG
OVERNIGHT WITH PATCHES OF DRIZZLE POSSIBLE AT TIMES. LOW STRATUS
CLOUDS HOWEVER SHOULD LIMIT FOG DEVELOPMENT SO CONFIDENCE IN
WIDESPREAD DENSE FOG IS NOT VERY HIGH.

TEMPERATURES WILL REMAIN NEARLY STEADY NEAR THE COAST WITH ONLY A
MINOR DROP IN TEMPS EXPECTED OVERNIGHT. MILDER OVERNIGHT TEMPS
WILL PREVAIL ACROSS THE INTERIOR OF NE FL WITH LOWS ONLY IN THE
UPPER 50S ALONG THE I-75 CORRIDOR.

&&

.AVIATION...

HIGH PRESSURE TO THE NORTH THIS EVENING...WILL PROVIDE FOR A
MOIST NORTH/NORTHEAST FLOW. THIS HIGH WILL WEAKEN AS IT SETTLES
SOUTH OVERHEAD INTO MONDAY. AS THE HIGH WEAKENS...WARM ADVECTION
WILL INCREASE FROM THE SOUTH. THIS WARM ADVECTION WILL CONTINUE
THE POTENTIAL FOR LOW CLOUDS AND FOG INTO EARLY MONDAY AS THIS
WARMER AIR ADVECTS OVER COOLER AREA WATERS.

AS A RESULT...LIFR/VLIFR ARE EXPECTED FOR TONIGHT. THE LOWERED
CONDITIONS MAY EXTEND THROUGH THE MORNING HOURS...THEN SLOWLY LIFT
INTO THE AFTERNOON.

&&

.MARINE...
WINDS CONTINUE TO DECREASE AND NORTHERLY WINDS WILL PREVAIL AT LESS
THAN 15 KNOTS OVERNIGHT. SEAS ARE ALSO SUBSIDING WITH GRAYS REEF
BUOY NOW DOWN TO 4 FEET. THE SMALL CRAFT ADVISORY FOR THE
OFFSHORE LEGS DUE TO LINGERING SEAS WILL BE ALLOWED TO EXPIRE THIS
EVENING AS SEAS CONTINUE TO SUBSIDE. THE ADVISORY WILL BE REPLACED
WITH A CAUTION STATEMENT TO ACCOUNT FOR LINGERING 4 TO 6 FT SEAS
OVER THE OFFSHORE LEGS TONIGHT.

RIP CURRENTS: HIGH RISK OVERNIGHT WITH A MODERATE RISK ON MONDAY.
