clouds are gradually clearing from west to east as yesterday`s cold
front tracks east. increasing clouds tonight as a shortwave
drops in from minnesota. while dew points are only in the
upper-20s, temperatures falling tonight into the 30s will help
narrow the gap, while pacific moisture advection and ample
forcing aides in a quick moistening of the profile. a cold
column could bring a couple of snow flakes. otherwise, a quick
dose of rain late tonight through the morning commute from west
to east is expected.
for the remainder of monday, the main vorticity maximum lies across
central michigan, likely keeping any lingering precipitation
north of our forecast area. cold high pressure sets up over the
great lakes monday night when lows will tumble well into the
20s; our coldest night of the week. the michigan state extension
office indicates a few fruit varieties could be susceptible to
these lows in the mid- 20s. back to 1990, our median last
28 degree hard freeze is april 11- 20. so, through that lens,
this cold is still within the bounds of climatology.
high pressure is overhead tuesday resulting in the coldest high
temperatures of the week; low-to-mid 40s. this shifts east by
wednesday in response to strong low pressure developing over the
canadian rockies. warm air advection quickly ramps up and we`ll be
in the 60s and 70s midweek.
we`ll keep a close eye on what could be a wet pattern late week. the
aformentioned low pressure sends a cold front through the midwest
that stalls against a strong southeast us ridge. the combination of
gulf moisture advection and the stalled front could spawn additional
heavy rain. the magnitude of the high pressure will be critical in
potentially steering this rain farther north out of the forecast
area.

clearing skies will be temporary this evening before a
disturbance pushes southeast over the area and increasing
clouds. cigs will lower between 09z and 11z mon and increase
chances of light rain showers with lowering of the vsbys in the
showers through 12z to 15z mon. as the disturbance moves
eastward out of the area some lake induced cloudiness should
remain through 18z mon when vfr cigs return. northwest winds
will remain gusty with gusts up to 25 kts through the taf
