lake effect clouds amid cyclonic flow departing the eastern great
lakes are showing some signs of breaking up. rising heights and a
subtle backing of the low-level flow should slowly chip away
the cloud deck for at least a couple peeks of sun late this
afternoon. decreasing clouds set us up for, in the context of
this mild fall, a very cold night. lows will tumble toward freezing
(away from the lake) as high pressure settles over illinois.
light wind to start the evening may set the stage for frost, but
then surface wind increases prior to daybreak in response to a
low pressure streaking across ontario. we`re now past the
climatological growing season; therefore, no frost/freeze
headlines.
breezy but dry on sunday as the aformentioned low passes to our
north. forecast soundings show strong flow in the low-levels but poor
mixing to the surface. this keeps wind gusts in check,
generally from the west at 25 to 30 mph. cool northwest flow
behind this dry frontal passage restarts lake effect clouds
which persist into monday morning.
broad northwest flow through the great lakes offers times of breezy
conditions for the week ahead, while a building ridge over the
central us results in a slight warming trend through wednesday
afternoon. given limited moisture transport, little to no rain is in
the forecast. our best chance for any rainfall is not until late
wednesday and thursday when a fairly deep trough approaches.
even so, this may be a glancing blow as low pressure from the
mississippi valley favors rain toward the ohio valley, shunted
south by an incoming great lakes trough. this trough sets up
lake effect precipitation, primarily west of our area.

mvfr to vfr conditions are expected at the terminals this
period, with an exiting low pressure trough heading eastward and
incoming surface high. persistent ovc/bkn skies will become
gradually more sct/few through the early evening, potentially
clearing completely at times. nw-wnw winds will shift to the
w-sw overnight into sunday, with gusts up to around 24kts during
the daytime hours.
