947 AM EST TUE FEB 28 2017

...WEST WINDS TO INCREASE ...

.SOUTH TO SOUTHEAST FLOW WILL INCREASE TODAY IN ADVANCE OF AN
APPROACHING LOW PRESSURE SYSTEM. RELATIVELY STABLE CONDITIONS
SUGGEST THAT WIND GUSTS SHOULD TOP OUT AROUND 25 KNOTS DURING THE
DAY OVER LAKE HURON. THIS PRIMARILY SOUTHERLY DIRECTION WILL ALSO
MINIMIZE WAVE CONCERNS OVER THE NEARSHORE WATERS. THE LOW PRESSURE
WILL SLOWLY TRACK THROUGH THE CENTRAL GREAT LAKES LATE TONIGHT INTO
WEDNESDAY.

STRONGER NORTH WINDS WILL DEVELOP AS THIS SYSTEM MOVES TO THE EAST,
AND WHILE A FEW GALE FORCE GUSTS WILL BE POSSIBLE OVER THE OPEN
WATERS OF LAKE HURON WEDNESDAY INTO WEDNESDAY NIGHT, IT APPEARS THAT
GUSTS TO AROUND 30 KNOTS WILL BE A MORE COMMON OCCURRENCE. GIVEN
THIS FACT, WILL HOLD OFF ON A GALE WATCH WITH THIS FORECAST AND
ALLOW THE MODEL SOLUTIONS TO BETTER DEFINE LOW PRESSURE STRENGTH AND
POSITION. WINDS WILL QUICKLY DIMINISH ON THURSDAY AS HIGH PRESSURE
BEGINS TO ENCROACH ON THE AREA. THIS HIGH WILL THEN BUILD ACROSS THE
AREA FRIDAY AND FRIDAY NIGHT.
