URGENT - MARINE WEATHER MESSAGE
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
403 AM EDT THU JUL 28 2016

...GUSTY AND PERSISTENT NORTHEAST WINDS TODAY THROUGH FRIDAY WILL
ALLOW WAVES TO BUILD...

.HIGH PRESSURE EXPANDING ACROSS THE NORTHERN GREAT LAKES TODAY WILL
FORCE A COLD FRONT INTO SOUTHWEST LOWER MI AND NORTHERN OHIO BY THE
END OF THE DAY. THE EXPECTED DEVELOPMENT OF WEAK LOW PRESSURE ALONG
THIS FRONT AND BUILDING HIGH PRESSURE ACROSS THE NORTHERN GREAT
LAKES WILL SUPPORT INCREASING NORTH-NORTHEASTERLY WINDS ACROSS THE
LAKES TODAY. GIVEN THE FETCH AND RELATIVELY WARM WATER TEMPERATURES,
THESE WINDS WILL BECOME RATHER GUSTY ACROSS SAGINAW BAY AND THE
SOUTHERN BASIN OF LAKE HURON. THE EXPECTED WINDS AND BUILDING WAVES
REMAIN SUPPORTIVE OF SMALL CRAFT ADVISORY CONDITIONS FOR THE
NEARSHORE WATERS OF LAKE HURON. THERE WILL BE SOME SLIGHT WEAKENING
OF THE NORTHEAST GRADIENT ON FRIDAY AS THE FRONTAL BOUNDARY AND WEAK
LOW PRESSURE SYSTEM SLIDES TO THE MID ATLANTIC. HOWEVER, THERE IS
STILL LIKELY TO BE SOME GUSTY WINDS OVER THE WARM NEARSHORE WATERS
OF LAKE HURON. FURTHER WEAKENING OF THE GRADIENT OVER THE WEEKEND
WILL SUPPORT REDUCED WIND SPEEDS AND WAVE HEIGHTS AND MORE
FAVORABLE BOATING CONDITIONS.
