Service.

.DISCUSSION...
Clouds build throughout the day on Sunday as the warm front of an
approaching low pressure slowly moves over us throughout the day and
evening. While southerly flow will initially be light early in the
day, expect it to pick up Sunday through Monday as the low approaches
from the Northern Plains towards western Lake Superior. While the
forecast calls for min RHs down around 40 percent, I wouldn`t be
surprised if we get down into the 30 percents given the soils. Expect
highs in the 50s on Sunday to give way to the lower 60s by Monday as
the warm front moves in. There could be some issues with ventilation
as the warm front goes through the area, with a strong inversion
setting up over the lower portions of the atmosphere by Monday. The
inversion over the area will be weakest on Sunday, when the effects
of the departing high pressure will still be felt. Rain showers and
thunderstorms could begin to impact the spot late Monday, and could
potentially continue on-and-off throughout the overnight hours. The
cold front could potentially bring a line of showers and
thunderstorms over the area early Tuesday morning before drier and
cooler weather is seen behind it.
