Severe Thunderstorm Warning 103, NWS Louisville, KY

Area Forecast Discussion
National Weather Service Louisville KY
256 AM EDT Tue May 9 2023

.Short Term...(Today and tonight)
Issued at 238 AM EDT Tue May 9 2023

A cold front will exit southern Kentucky early this morning, pushing
any lingering showers and storms out of the state. Low level
moisture manifesting itself in low clouds from Illinois to Ohio
overnight will move southward into the Ohio Valley this morning,
gradually lifting and scattering this afternoon. With a north breeze
and falling dew points, it should feel quite pleasant outside with
afternoon highs in the 70s.

Tonight high pressure will build southward from the Great Lakes and
supply us with mostly clear skies and a light northeast breeze.
Temperatures will tumble into the lower 50s and upper 40s. There may
be some fog development right along rivers and streams in the more
sheltered valleys, but dry air and a light but steady northeast
breeze should prevent widespread fog.

&&

.Long Term...(Wednesday through Monday)
Issued at 256 AM EDT Tue May 9 2023

Wednesday and Wednesday night high pressure over the Great Lakes
will slide southeastward to the East Coast, keeping our weather dry.
Went a bit below guidance for dew points Wednesday afternoon with
good mixing. As we get into the late week, return flow will set up
with increasing warmth and moisture along with chances of
showers/storms, especially during the afternoon and evening hours
each day. This weekend a cold front will approach from the west,
further supporting the idea of scattered shower/storm chances. Could
see some briefly strong pulsers, especially Friday and Saturday, in
very unstable but weakly sheared atmosphere. Afternoon highs will be
in the 80s with morning lows only in the 60s.

&&

.Aviation...(06Z TAF Issuance)
Issued at 125 AM EDT Tue May 9 2023

A cold front stretched out along the Ohio River will advance
southward to the Tennessee line during the pre-dawn hours, gradually
pushing showers and storms south. Low clouds, some of which have
already developed from northern Illinois to northern Ohio, will fill
in behind the front for several hours this morning before lifting to
VFR this afternoon and possibly scattering out. Tonight high
pressure expanding from the Great Lakes into the Ohio Valley will
provide aviators with clear skies and a light northeast breeze.
