.Forecast Update...

No significant forecast updates this evening. Skies remain clear,
and temps have dropped into the low to mid 50s in most places. A
handful of locations that have seen at least briefly calm winds have
quickly dipped into the 40s. The forecast lows in the mid 30s for
Wednesday morning are on track.

.Short Term...(This evening through Wednesday)
Issued at 230 PM EDT Tue Oct 23 2018

Strong sfc high over the Upper Midwest will build into the Great
Lakes by late Wednesday, with low-level cold advection as the main
player in the Ohio Valley. Light north winds tonight will keep temps
from bottoming out completely, but we will still run solidly below
normal for late October, with lows generally in the mid/upper 30s.
Low-level winds come around to NE by Wed afternoon, holding max
temps 10-15 degrees cooler than today even under full sunshine.

.Long Term...(Wednesday night through Tuesday)
Issued at 225 PM EDT Tue Oct 23 2018

The long term period will be characterized by cool and periodic wet
weather as the region is influenced by upper level troughing. Rain
chances could return as soon as Thursday evening to southern KY as
an area of low pressure skirts along the Gulf Coast states, and
isentropic lift north of the low aids in the development of
precipitation. Most of Friday is looking to be being completely wet
and soggy for all of southern Indiana and central Kentucky. We'll
begin to see some breaks in the rain Saturday as the low departs to
the northeast, but a strong shortwave diving in from the northwest
will bring another round of showers Sunday and Monday.

.Aviation...(00Z TAF Issuance)
Issued at 718 PM EDT Tue Oct 23 2018

VFR weather is expected throughout this TAF period with mainly clear
skies. The low levels of the atmosphere look a bit too dry to
support fog at the terminals early Wednesday. Any fog should be
limited to river valleys. Expect a light north breeze around 5 kts
overnight, becoming northeast Wednesday morning. Winds will increase
to 7-10 kts after 14z.
