Tuesday will host a mostly sunny day, with some diurnal cumulus clouds expected in the afternoon. Winds will primarily be out of the south to southwest with gusts up to 15 mph. Conditions for good smoke dispersal will depend on the amount of influence from Lake Superior. Little to no influence will lead to mixing heights to a maximum of 5000ft in the afternoon, higher than forecasted. This is more likely since southwest flow tends to limit the lake`s influence. .TUESDAY... Sky/weather.........Sunny (15-25 percent). Chance of pcpn......10 percent. LAL.................1.
