.DISCUSSION...
Key Message 1)

A mid level shortwave passing thru the Great Lakes this morning
will help carve out a larger scale trough across the eastern US.
This will result in a northwest flow pattern across the Ohio Valley.
At the surface a weak cold front will pass thru ILN/s FA this
evening. The air mass has very limited moisture - so no pcpn is
expected.


At
the same time, a midlevel anticyclone will remain in place across the
western US. This pattern will favor northwesterly flow across much
of the eastern half of the country, in turn supporting reinforcing
shots of cooler air.

A modest drop in temperatures will follow for a couple of days as
surface high pressure of Canadian origin builds in from the
northwest behind the front. This high departs to the east by midweek
and allows for returning southerly flow , allowing somewhat warmer
air.

Another cold front will push into the area later Wednesday into
Thursday. However, moisture will still be limited, so rain is not
expected.

Model solutions indicating a warm up late in the week into next
weekend as a mid level ridge builds into the region. Rain chances
increase for the second half of next weekend as a system approaches
from the south.

.AVIATION /06Z SUNDAY THROUGH THURSDAY/...
Weak high pressure and a dry air mass was leading to VFR conditions
with only some high level clouds. Light winds and mainly clear skies
will lead to the potential for some river valley fog overnight. Have
MVFR to IFR vsby and celling restrictions at KLUK.

Fog improves quickly after sunrise with VFR conditions thru the
remainder of the TAF forecast.

OUTLOOK...No significant weather is expected.
