...STRONG WINDS AND HIGH WAVES TO CONTINUE INTO MONDAY...

.EAST FLOW WILL GRADUALLY BECOME SOUTHEAST TONIGHT AS DEEPENING LOW
PRESSURE PUSHES A WARM FRONT THROUGH THE AREA. DURING THIS TIME
FRAME...EXPECT STEADILY INCREASING WIND SPEEDS WHICH WILL ALLOW
WAVES TO BUILD. AS THIS LOW PASSES INTO THE NORTHERN GREAT LAKES
MONDAY...WINDS REMAIN GUSTY AND VEER TO THE SOUTH AND THEN SOUTHWEST
AS A COLD FRONT SWEEPS AROUND THE BASE OF THE EXITING LOW PRESSURE.
SMALL CRAFT ADVISORIES WILL CONTINUE INTO MONDAY. WHILE A FEW GUSTS
MAY APPROACH GALE FORCE...THE MARINE LAYER LOOKS TO BE FAIRLY STABLE
WHICH WILL LIMIT THIS POTENTIAL. WINDS WILL SUBSIDE TO SOME EXTENT
FROM MONDAY NIGHT INTO TUESDAY AS THE LOW STALLS NEAR JAMES BAY AND
BEGINS TO SLOWLY WEAKEN.
