NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
354 AM EDT SUN JUN 25 2017

...WESTERLY WINDS GUSTING AROUND 25 KNOTS TODAY...

.AN INCREASE IN WINDS IS EXPECTED TODAY AS THE PRESSURE GRADIENT
TIGHTENS BETWEEN A TROUGH OF LOW PRESSURE TRACKING THROUGH NORTHERN
LAKE HURON AND HIGH PRESSURE BUILDING INTO THE PLAINS AND TENNESSEE
VALLEY. THE STRONGEST WINDS WILL BE LOCATED OVER LAKE ST CLAIR AND
WESTERN LAKE ERIE, WHERE GUSTS SHOULD REACH ABOUT 25 KNOTS. A SMALL
CRAFT ADVISORY REMAINS IN EFFECT FOR THESE LAKES TODAY. ANOTHER
ROUND OF GUSTY WINDS LOOKS TO DEVELOP MONDAY AS ANOTHER AREA OF LOW
PRESSURE TRACKS THROUGH NORTHERN MICHIGAN. THIS COULD AGAIN
NECESSITATE SMALL CRAFT ADVISORIES. OFFSHORE WESTERLY FLOW WILL
LIMIT WAVE GROWTH EACH DAY. THERE IS ALSO A SLIGHT CHANCE FOR
THUNDERSTORMS TODAY AND MONDAY AS THE AIRMASS REMAINS UNSTABLE. HIGH
PRESSURE EXPANDING INTO THE GREAT LAKES WILL THEN BRING SOUTHERLY
FLOW AND DRY WEATHER FROM LATE MONDAY NIGHT INTO WEDNESDAY EVENING.
