high pressure over lake huron is drifting east in response to an
incoming upper-level trough. plenty of sunshine this afternoon with
highs in the 60s thanks to east-southeasterly flow from the departing
high pressure. tonight, clouds from the aformentioned trough will
generally pass north of the area, but perhaps some high clouds
drifting across the southern michigan state line. the trough axis
passes by sunday morning with the trailing surface cold front to
follow. this results in a 8 to 10 degree temperature difference in
the afternoon due to northwesterly flow developing off lake
michigan. downwind locations will see highs only in the 60s, while
those along and south of us 24 will see mid-70s. an absence of deep
moisture yields a rain-free frontal passage.
during this tranquil period of weather, our primary talking point
remains tuesday morning low temperatures in the 30s as high pressure
becomes centered overhead. frost remains a possibility, especially
along the southern michigan state line. otherwise, warming
thereafter with high pressure moving east once more and rising upper-
level heights and dry conditions.

no major flight concerns expected despite the passage of a cold
front sunday morning. winds will eventually shift from the
southeast to the southwest and eventually northwest by the end
of the forecast period.
