...Updated Aviation Discussion...

.Short Term...(This evening through Monday night)
Issued at 228 PM EDT Sun Sep 24 2017

Surface analysis reveals a near stationary 1023mb surface high in
western New York that is influencing the weather in the lower Ohio
River Valley region. Surface obs are picking up on a subtle boundary
across southern Kentucky where some surface convergence is
occurring. A quick look at visible satellite reveals some agitated
cumulus along that boundary that are trying to develop into
thunderstorms. Regional radars show very little in the way of echo
returns, but expect activity to pick up here shortly as peak heating
occurs. Rest of the region north of that boundary should remain dry
and warm this afternoon.

Expect another mild evening with patchy fog in the usual river
valleys and low lying areas. Tomorrow`s weather will be nearly
identical to today, except that the whole region should remain dry
as capping in the low-to-mid levels increases.

.Long Term...(Tuesday through Sunday)
Issued at 235 PM EDT Sun Sep 24 2017

Hot and dry weather will continue into Wednesday before a cold front
ushers in a more fall-like airmass. The fropa on Wednesday still
looks to be mainly dry due to limited moisture, with the best chance
for any measurable precipitation in southern Indiana. Another
reinforcing shot of cooler air will arrive over the weekend, and
keep daytime highs around or just under the 70 degree mark.


.Aviation...(00Z TAF Issuance)
Issued at 654 PM EDT Sun Sep 24 2017

Showers and storms across southern KY will continue to quickly
dissipate in the next hour.  Scattered mid-high level cloudiness
will remain for a while, but should clear out by 25/02-03Z.  For the
overnight period, high pressure will remain in control yielding
mostly clear skies and light winds.  Locally dense fog will be
possible again at the usual fog prone areas.  The outlook for Monday
is for VFR cigs/vsbys with light winds.
