.DISCUSSION...
A LIGHT LAKE BREEZE OFF OF LAKE SUPERIOR WILL DEVELOP AROUND THE
NOON HOUR. THE BURN LOCATION IS EXPECTED TO REMAIN ON THE COOL
SIDE OF THE LAKE BREEZE WITH LIGHT SOUTH TO SOUTHWEST WINDS AND
NEAR STEADY OR POSSIBLY FALLING TEMPERATURES THROUGH THE
AFTERNOON. THE LAKE BREEZE WILL ALSO BRING INCREASING RELATIVE
HUMIDITY VALUES THROUGH THE AFTERNOON. THE FULL EFFECT OF THE LAKE
BREEZE ON THE BURN IS SOMEWHAT DIFFICULT DUE TO THE LIGHT WINDS
KEEPING THE TRANSITION ZONE FROM COOL MARINE AIR TO WARMER/DRYER
INLAND AIR CONFINED TO ONLY A FEW MILES INLAND FROM LAKE SUPERIOR.
