.DISCUSSION...
KEY MESSAGE 1)
Areas of fog will develop through the predawn hours, especially in
the river valleys across our south and east. The fog will burn off
through mid morning, with quieter conditions expected through the
rest of the day.

Some mid level energy moving across the Great Lakes tonight will
help deepen the trough over the region through the day on Saturday as
a secondary short wave pivots through the mid Ohio Valley Saturday
into Saturday night. As we destabilize ahead of this, MLCapes will
push into the 1500-2000 J/KG range through the afternoon on Saturday.
As a result, expect scattered shower and thunderstorm development as
we head into the afternoon, with this activity shifting east across
our area through late afternoon and early evening. Increasing mid
level flow will allow for marginal deep layer shear of 20-30 knots,
so a few strong to severe storms will be possible Saturday afternoon
into early evening. The main threat will be isolated damaging wind
gusts, but some cooler air moving in aloft may also support some hail
in the stronger updrafts.

&&

.AVIATION /04Z FRIDAY THROUGH TUESDAY/...
Expect areas of fog to continue to develop through the predawn
hours, mainly affecting the more favorable locations of KLUK, KILN
and KLCK, where some IFR conditions will be possible. Depending on
how widespread the fog becomes, we could see a period of MVFR cigs
linger into mid morning as the fog lifts. Otherwise, expect mainly
just some sct-bkn VFR CU from late morning through the afternoon.
Skies will clear heading into this evening with some areas of fog
again possible late tonight.

OUTLOOK...Thunderstorms possible Saturday afternoon and evening.
