Given warm temperatures and light southerly winds expected on Monday a lake breeze is expected to form off Lake Superior and there is some uncertainty on the inland extent of this lake breeze in the afternoon. At this time, expect the lake breeze to get held up just north of the burn area allowing for light southerly winds to prevail, but if this lake breeze boundary reaches a few more miles inland it could result in variable winds or winds switching from light southerly to light northerly in the afternoon. Mixing to 5 kft will allow for good smoke dispersion and could allow for drier dew points and lower RHs in the afternoon as well. Expect min RHs around 25% over the burn area. Southeast winds will be increasing Monday night into Tuesday in advance of a low pressure approaching from the Plains. Showers from this system are expected to reach the burn area mainly in the afternoon on Tuesday. .MONDAY... Sky/weather.........Sunny (10-20 percent). Patchy fog early in the morning.
