NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
949 AM EDT SUN APR 19 2015

...STRENGTHENING EAST WINDS TO BRING BUILDING WAVES...

.HIGH PRESSURE CENTERED OVER THE ONTARIO AND QUEBEC BORDER HAS
SET UP EASTERLY FLOW ACROSS THE REGION. THIS FLOW WILL INCREASE
TODAY AS LOW PRESSURE DEEPENS AND LIFTS TOWARD THE GREAT LAKES
FROM THE SOUTH. SMALL CRAFT ADVISORIES HAVE BEEN ISSUED FOR ALL
NEARSHORE ZONES AS GUSTY WINDS BUILD WAVE HEIGHTS ALONG THE
SHORELINES NOW INTO EARLY MONDAY. THOUGH SOME GUSTS MAY APPROACH
GALE FORCE...THE MARINE LAYER LOOKS TO BE FAIRLY STABLE WHICH WILL
LIMIT THIS POTENTIAL. AFTER STALLING A BIT OVER THE REGION
TONIGHT...THE LOW WILL LIFT NORTHWARD TO NEAR JAMES BAY BY MONDAY
NIGHT. THIS WILL ALLOW WINDS TO GRADUALLY RELAX THROUGH THE DAY
MONDAY.
