.DISCUSSION...
KEY MESSAGE 1...

A large expansive trough departs the region into early next week.
Before it does so, weak disturbances within the trough will provide
chances for showers tonight and continued cloud cover into Sunday
night. Due to the cloud cover forecast, the diurnal temperature curve
was flattened from the baseline NBM, making the daytime highs a bit
cooler today and Sunday and the nighttime lows slightly warmer.
Forecast soundings are very dry in the mid and upper levels tonight,
but a weak disturbance dropping south out of the Great Lakes may
provide enough forcing. Low-level lapse rates remain steep given the
constant cold air advection, supporting these low level showers. The
coverage of showers should be pretty scattered tonight, with most
locations dry to start Sunday morning.

High pressure builds over the region Monday, helping to erode away
any remaining moisture and low-level cloud cover by the afternoon.
Temperatures climb back into the 50s, which is much closer to
seasonal normals. The same high pressure shifts to the east of the
region midweek, supporting additional warming across the area. Above
normal temperatures then persist through the end of the week.

A weak trough may move through the Great Lakes and upper Midwest on
Thursday, but at this time, conditions look too dry to allow for any
renewed chances of rainfall.

&&

.AVIATION /18Z SATURDAY THROUGH WEDNESDAY/...
Cloud coverage has expanded across the area, providing low-end VFR to
MVFR CIGs to all sites. MVFR CIGs persists for most locations this
afternoon before climbing back to VFR. A weak system brings the
chance for showers and periodic MVFR CIGs, but given the lower
probability, held off mention in the TAF. Cloud cover linger into
Sunday, with primarily low-end VFR CIGs expected. Resumed MVFR CIGs
for the northern most sites (DAY/CMH/LCK).

Winds remain persistent out of the northwest throughout the period,
generally between 10-13kts. Occasional gusts to 20 knots are possible
at times, but infrequent enough to keep mention out of the TAF.

OUTLOOK...No significant weather expected.
