DISCUSSION
ISSUED AT 955 PM EST SUN JAN 4 2026
DEW POINTS HAVE JUMPED UP 5 TO 10 DEGREES OVER THE PAST 24 HOURS
AND ARE NOW SITTING NEAR 70. THIS INCREASE IN MOISTURE IS
ASSOCIATED WITH A DYING FRONT THAT PUSHED INTO THE KEYS ARE TODAY.
A FEW SHOWERS WERE EVIDENT ACROSS THE BROADER THROUGH THE DAY AND
EVENING, BUT HAVE REMAINED WELL AWAY FROM THE ISLAND CHAIN. WINDS
HAVE SHIFTED NORTHEASTERLY BUT REMAIN QUITE WEAK.
EXPECT WINDS TO REMAIN LIGHT AND LOOSELY NORTHEASTERLY THROUGH THE
OVERNIGHT PERIOD AS HIGH PRESSURE, CENTERED OFF THE ATLANTIC COAST
MOVES FURTHER OUT TO SEA. ESSENTIALLY NO SIGNIFICANT SHIFT IN
AIRMASS IS EXPECTED AND OVERNIGHT LOWS WILL RANGE BROADLY IN THE
MID 60S WITH VERY LITTLE IN THE WAY OF DEW POINT DEPRESSION.
STABLE CONDITIONS WILL PERSIST WITH GOOD DRYING HOLD ON THROUGH
THE LOWER AND MID LEVELS. THIS ALONG WITH PALTRY FORCING WILL KEEP
RAIN CHANCES OUT OF THE FORECAST FOR OVERNIGHT.
MARINE
ISSUED AT 955 PM EST SUN JAN 4 2026
