.DISCUSSION...
KEY MESSAGE 1)
Remnant showers and embedded thunderstorms moving across the region
will quickly pass off to the east early this morning.

Cold front extending from northwest Ohio into southern Illinois will
move across the region this afternoon. Additional showers and
thunderstorms will develop along and ahead of the boundary. The
deeper plume of precipitable water will be decreasing and shunting
off to the southeast, although values will still be quite high. And
deep warm cloud depths will remain in place, so locally heavy rain
will still be possible. Environment looks pretty marginal for any
severe, although cannot rule out a few stronger storms.

KEY MESSAGE 2)
Dew points will drop back into the 60s in the wake of Monday`s cold
front, and temperatures will fall to or a bit below normal. Moisture
will increase once again on Wednesday ahead of an approaching cold
front, although not to the degree that has been the case for much of
the past week. The front will sag through the area Wednesday night
into Thursday morning as minor impulses of energy move through the
base of a long wave trough that is slowly shift eastward. Showers and
possibly some storms could linger in southern counties into Thursday
night when a more energetic short wave move southeast into the
Tennessee Valley giving the front a stronger push south. After this
front passes, even cooler conditions will prevail through the end of
the week with highs in the mid 70s to around 80 and lows in the mid
50s to lower 60s.
