.SYNOPSIS...
A slow moving front and low level moisture will lead to areas of
dense fog this morning. Low pressure and another cold front will
move through tonight into Sunday morning. Considerably colder air
will move into the region with rain changing to snow Sunday. A chance
for snow will continue into Monday bringing the potential for the
first light snow accumulations of the season.

.NEAR TERM /THROUGH TONIGHT/...
6:15 AM update...
Drier air has slowly advected into the western portion of the dense
fog advisory. This has resulted in an improvement to the widespread
dense fog. Therefore, have removed a tier of counties across the west
from the dense fog advisory.

Previous discussion...
In between systems today with mid level energy and robust short wave
digging southeast from the northern Plains into the Mid MS River
Valley by evening. Ahead of this system - weak low level flow,
stalled front, and abundant low moisture has led to the development
of areas of fog. Dense fog was reported generally along and east of
I-71. The fog is affecting travel - so have continued a dense fog
advisory until mid morning.

After the fog and stratus improves this morning expect WAA mid and
high level clouds to pivot thru the area ahead of the next system.
High temperatures to range from the lower 50s north to the lower 60s
south.

&&

.SHORT TERM /SUNDAY/...
A short wave over the Mid MS River Valley head more east tonight
across the Ohio Valley. A compact surface low will track along a
stalled east-west front, with the model solutions continuing to
take this low from east central Indiana acrs central Ohio overnight.

Expect widespread rain along and north of the low track. Lessor chances
of rain further south along the trailing cold front. Lows tonight
range from the mid 30s northwest to the lower 40s southeast.

Short wave and associated surface low may still be near central Ohio
Sunday morning will quickly move off to the east. Lingering system pcpn
looks to end thru the morning. Early highs drop as low level CAA
develops. Rain will likely mix with and chance to snow across the
north prior to diminishing. Flow off the lakes and low level CAA will
likely lead to showers into the afternoon with a mix and change over
to snow across all but the far southeast. Due to a warm ground and
daytime temperatures falling into the mid and upper 30s - do not
expect much in any accumulation thru the afternoon.

&&

.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
Mid-level low will dig south from the Upper Midwest into the Lower
Ohio Valley Sunday night, then further southeast into the Tennessee
Valley on Monday. Very cold temperatures aloft will follow the path
of the closed low center, with shallow instability represented on CWA
forecast soundings on Monday. This will likely bring periods of snow
showers. Can`t rule out minor/temporary accumulations Sunday
night... however solar insolation and lingering warm ground
temperatures will keep this from occurring to any significant extent
during the daytime hours on Monday.

Temperatures will be well below normal Sunday night through Monday
night, with a hard freeze occurring both nights. Gusty northwest
winds will produce apparent temperatures in the teens at night and
in the 20s Monday and most of Tuesday.

The upper low will begin to pull away to the east toward midweek,
allowing highs to return to around 40 on Tuesday and the 50s on
Wednesday through Friday. We will likely see a decreasing trend in
sky cover starting Wednesday.

&&

.AVIATION /11Z SATURDAY THROUGH WEDNESDAY/...
Weak low level flow, stalled front, and abundant low moisture has
led to the development of areas of fog and stratus. Low IFR
conditions with dense fog and stratus was reported at KLUK, KILN,
KCMH, and KLCK - with MVFR conditions at KCVG. Drier air was keeping
KDAY VFR. Expect these conditions to improvement thru mid morning
with sunshine and continued advection of some drier air.

After the fog and stratus improves this morning expect WAA mid and
high level clouds to pivot thru the area ahead of the next system.

Rain to move into the region late tonight ahead of an approaching
low pressure system. Have a mention of light rain after 08Z into the
west with MVFR ceilings and visibilities developing late and
overspreading all TAF sites early Sunday.

OUTLOOK...MVFR ceilings and visibilities are likely Sunday with IFR
ceilings possible. MVFR ceilings will likely linger into Monday.
