SYNOPSIS
WINDS WILL SETTLE THIS AFTERNOON AS HIGH PRESSURE BECOMES
SITUATED OVER THE AREA THROUGH FRIDAY NIGHT BEFORE A POWERFUL
ARCTIC FRONT PLUNGES ACROSS THE WATERS SATURDAY. THIS VERY STRONG
FRONT WILL BRING STRONG WINDS AND GUSTS ACROSS THE WATERS SATURDAY
WHICH WILL STRENGTHEN TO GALE-FORCE SATURDAY NIGHT AS A LOW
PRESSURE ORGANIZES AND DEEPENS QUICKLY OFF THE COASTAL CAROLINAS.
THERE WILL BE A LOW CHANCE OF A MIX OF RAIN AND SNOW SHOWERS
ACROSS THE WATERS SATURDAY NIGHT AS MOISTURE WRAPS AROUND THE LOW
AND THIS MAY LEAD TO OCCASIONAL PERIODS OF LOW VISIBILITY. HIGH
PRESSURE WILL BUILD FROM THE WEST AND OVER THE WATERS DURING THE
EARLY AND MIDDLE PART OF NEXT WEEK.
