.DISCUSSION...

EXPECT A SUNNY AFTERNOON NEAR THE LAKE SUPERIOR SHORELINE IN THE
ARROWHEAD TODAY. THE WINDS WILL BE VERY LIGHT AND VARIABLE AROUND THE
PROPOSED BURN TIME, BUT LIGHT SOUTHEAST TO EAST WINDS AROUND 5 MPH
WILL DEVELOP DURING THE MID TO LATE AFTERNOON. TEMPERATURES, AS WELL
AS RELATIVE HUMIDITY, WILL BE TRICKY TODAY DUE TO THE WINDS COMING
OFF THE LAKE. MY BEST GUESS IS THAT THERE WILL BE STILL BE SOME WARMING
THROUGH EARLY THIS AFTERNOON DUE TO THE NEGLIBLE WINDS. THE TEMPERATURE
MAY EVEN PEAK A LITTLE ABOVE 60, BUT I THINK THE TEMPERATURE WILL BEGIN
TO DECREASE LATER THIS AFTERNOON WHEN THE WINDS OFF THE LAKE BEGIN TO
DEVELOP. PLEASE BE PREPARED FOR EVEN HIGHER TEMPERATURES AND LOWER
HUMIDITY IF THE WINDS DO NOT KICK IN QUICKLY ENOUGH OR DO NOT HAVE THE
EXPECTED COOLING EFFECT.
