.DISCUSSION...
KEY MESSAGE 1)
Some showers and isolated thunderstorms have developed near the
Interstate 71 corridor this evening. Expect some additional activity
to develop generally near this corridor and points southeast for the
evening into the first part of the night before dissipating. Already
had one report of a funnel cloud in Madison county earlier. Typically
in this environment these funnels rarely touch down and if they do
they are very weak. Some patchy fog will then be possible in river
valleys and some locations southeast of Interstate 71 overnight.
Anomalous upper level ridging extends eastward into the Great Lakes
and Ohio Valley this week while high pressure at the surface remains
over the region. Hot conditions, with highs in the lower 90s are
likely through at least Thursday. Peak afternoon heat index values
reach into the upper 90s to near 100 when factoring in dew points in
the upper 60s. The hottest day of the week will likely be Wednesday.
Borderline Heat Advisory conditions are expected the middle of this
week with dew points being the main limiting factor.
The upper level ridge starts to break the end of this week when a
low pressure system is forecast to move through the Great Lakes.
Shower and storm chances increase with this low moving into the
region this weekend and temperatures cool slightly.

.AVIATION /00Z TUESDAY THROUGH SATURDAY/...

of the activity is not near the TAF sites, cannot rule out a brief

be the potential for some fog development overnight. Have MVFR vsbys
developing at KDAY, KCMH, and KCVG. Have IFR vsbys developing at
KLCK, KILN, and KLUK. VFR conditions will return on Tuesday and some
cu will be possible. Winds will generally be light and around 10
