lake effect snow showers have diminished this afternoon with
dry air and cloud tops becoming problematic. however, two
periods of renewed les are anticipated; the first is this
evening and the second is friday night. declining multiband
snow showers this afternoon have given way to a single-band
currently hugging the eastern lake michigan shoreline. this
passes through michiana this evening ahead of a strong upper-
level trough dropping in from the hudson bay. this east- west
oriented trough results in a transient band of snow ultimately
headed for il by daybreak friday. as this evening`s band passes
through, the inland extent of snow appears to be limited,
resulting in snow accumulations confined to southern berrien and
northern la porte. residence time will be brief, yet forecast
soundings are otherwise adequate with about 6-8k ft equilibrium
levels and a saturated dendritic growth zone for most of the
profile. portions of berrien or la porte could pick up a quick
inch or two of snow (1.9" recorded this morning from a cocorahs
observer 7.4 sw of niles) before the band reaches northwest
illinois. overall, appears to be another round of nuisance lake
effect snow.
friday evening, the lake effect band sloshes back to the east most
likely impacting extreme western la porte co near/after 6pm cst
friday. forecast soundings depict a continued favorable environment
with an eql near 8k ft and a well saturated dgz. yet, given
differing solutions and uncertain timing, will hold off on any
headlines. very cold in the wake of this trough, especially outside
of any lake effect clouds. minimum wind chills friday night/saturday
morning for northwest ohio will be near -15f, thus, a cold weather
headline will be needed within the next 24 hours (held off to avoid
any school-related confusion).
arctic high pressure is entrenched over the weekend keeping
conditions cold, but a warm-up into the mid-20s begins monday
as upper- level ridging develops over the western 2/3 of the
conus. how this ridge evolves is uncertain with guidance split
on how and where low pressure develops midweek. next weekend
could feature another clipper and dose of cold air.

a single lake effect band that impacted ksbn for a few hours
has shifted east of the site as a notable meso low (southwest of
kekm) was moving se. ksbn should see vfr conditions into the
overnight hours, before upstream redevelop occurs behind a
strong west to east trough, with this band possibly clipping
ksbn before shifting west of the site for the duration of the
period.
kfwa should be largely vfr, but will need to watch movement of
the meso low over the next couple of hours for brief impacts.
