...DENSE FOG OVER THE WATERS THROUGH TONIGHT...

.LIGHT TO MODEST SOUTHERLY WINDS ARE ADVECTING VERY MOIST AIR ATOP
THE COLD LAKE SURFACE, RESULTING IN DENSE MARINE FOG ACROSS LAKE

A CHANCE FOR SOME GALE FORCE WIND GUSTS. GUSTY WINDS WILL THEN ENSUE
FRIDAY NIGHT INTO SATURDAY AS THE SYSTEM LIFTS NORTHEAST OF THE
REGION, WITH AGAIN A CHANCE FOR SOME GALE FORCE GUSTS.
