...BRIEF GALES EXPECTED OVER CENTRAL LAKE HURON LATE TOMORROW...

.VERY LIGHT WINDS AROUND TODAY AS HIGH PRESSURE WILL BE IN CONTROL.

HURON BY 00Z FRIDAY...BUT THE DURATION IS IN QUESTION...AND NOT
SURE IF THEY WILL LAST 3 HOURS OR MORE. NONE-THE-LESS....ELECTED TO
ISSUE A GALE WATCH TO COVER THIS POSSIBILITY. THE COLD AIRMASS
STREAMING IN THURSDAY NIGHT WILL ALLOW FOR JUST A SLOW DECREASE IN
THE NORTHWEST WINDS...AS THE WANING PRESSURE GRADIENT IS OFFSET BY

LIFTING INTO THE REGION FRIDAY WILL FLIP THE WINDS TO THE
SOUTHWEST/SOUTH BY FRIDAY EVENING...WITH GUSTS OF 25 TO 30 KNOTS
EXPECTED OVER MUCH OF LAKE HURON BEFORE MILDER AIR AND GREATER
STABILITY ARRIVES OVER THE WEEKEND.
