.SYNOPSIS...
An upper level low pressure system will push slowly east across
the Tennessee and Kentucky through Tuesday, bringing rain
showers to the region. High pressure and drier conditions will
return for mid week. Cooler than normal high temperatures will
persist through the end of the week.

&&

.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
Scattered to numerous showers will continue to pivot across the
region and then diminish in coverage for the overnight hours.
Clouds and easterly winds will keep temperatures from falling
much from early evening readings.

&&

.SHORT TERM /6 AM TUESDAY MORNING THROUGH TUESDAY NIGHT/...
On Tuesday, the center of the upper low will lift into eastern KY. A
rain band will lift northeast through the portions of the area
in the morning, before coming scattered by afternoon. Below
normal temperatures are expected on Monday as highs will be in the
upper 50s to lower 60s.

Tuesday night the upper low pulls off into the Appalachians.
Drier air will begin to work in from the west, but there will
be a lingering chance of showers.

&&

.LONG TERM /WEDNESDAY THROUGH MONDAY/...
High pressure will settle over the Ohio Valley on Wednesday with the
next chance for rain occurring late Friday and Friday evening as an
upper level trough moves towards the east coast.  Another surface
high will build behind it on Saturday with a return to southerly
flow and warmer air advection occurring Sunday into next week.

Temperatures will be muted through Saturday with highs in the upper
50s to lower 60s, then rise into the 60s and 70s for early next
week. Overnight lows in the upper 30s to lower 40s will occur until
the warmer daytime temperatures early next week inhibit nighttime
dropoffs.

Any lingering rain on Wednesday or the period of showers expected on
Friday should be relatively light in nature.

&&

.AVIATION /00Z TUESDAY THROUGH SATURDAY/...
Showers will continue to rotate across the region early in the
period. These could bring a temporary period of MVFR conditions,
except at the Columbus terminals which should remain VFR. As
showers diminish tonight, VFR will prevail. However, another
surge of showers will spread north into the region towards or a
little after 12Z. It appears that this will lower conditions to
MVFR initially, but moistening of the low levels will eventually
cause ceilings to drop to IFR. These IFR ceilings will persist
through the end of the TAF period even as precipitation
diminishes again late.

OUTLOOK...IFR ceilings and MVFR visibilities will likely
continue Tuesday night into Wednesday morning.
