.SYNOPSIS...
A strong upper level longwave trough will cross the region as it
moves eastward today. Ahead of this, showers and some thunderstorms
will occur and spread northeast and be found generally east of the
I-71 corridor. Friday will mark the end of any rain in the region,
with little found for the remainder of the forecast.
&&
.NEAR TERM /THROUGH TONIGHT/...
Rain over nrn KY with some isolated pockets of deeper convection
producing thunder will persist, with the eastern edge making a gentle
northern push along the Scioto River. In the next few hours, the
region of rain will remain in nrn KY but then extend more ne versus
just e as it is currently found. NW of the I-71 corridor is not
necessarily dry this morning, but will be scattered in nature and
transient. Rainfall rates are exceeding 1"/hr over portions of nrn KY
where the convection is strongest, and the area near the Bracken,
Pendleton, Robertson intersection seems to have been influenced by a
weak mesovort, and an advisory has been placed for this area attm.
This area of rain will continue to see a ne movement in the cells and
precip this morning. The upper low in the l/w trough is pushing into
nw OH this afternoon. Rain will scatter out well ahead of it with
most of the CWA showing a marked decrease towards noon, and some very
light showers then evolving into passing sprinkles by early evening.
Low cloud cover and precip will keep today`s highs in the mid-upper
70s.
&&
.SHORT TERM /FRIDAY/...
Clearing overnight is expected to occur in the late evening, at least
for a few hours. If it truly clears and the boundary layer is
permitted to radiate, expect a ground level stratus deck to form,
likely leading to areas of dense fog. Overnight lows will bottom out
in the mid 50s for most locations, coolest over IN and west central
OH and warmest over KY and Scioto County.
The upper pattern should split with the stronger low and vort maxima
tracking east, splitting off of a remaining circulation to the south
that meanders further south into southern KY by late day. With the
atmosphere being worked over the past several periods, sky cover will
clear out and temperatures will rise into the upper 70s with a light
northerly/nw wind around 5-8 mph.
&&
.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
Heading into the weekend, a pesky but weak upper level low continues
to meander over the Ohio Valley and Appalachians. So despite the
ridge building over the central CONUS into the Great Lakes, the upper
level low will supply potential for clouds and even some shower
activity. Mid and upper level clouds extend throughout the area, but
any showers are limited to southern/southeast Ohio and northeast
Kentucky. High and low temperatures a few degrees above normal but
steady day to day.
Early next week, tropical activity in the western Atlantic will
interact with the upper level low, complicating its evolution. The
overall weather remains similar to the weekend with occasional
clouds with the potential for showers across far southeast portions
of the local area (southern Ohio, northeast Kentucky). Until the
tropical situation becomes more clear, confidence is low on how
quickly the upper level low clears out of the region.
Toward the end of the period, there are some hints that the central
CONUS ridge builds more firmly over the local area, settling the
Ohio River region into a renewed dry stretch.

.AVIATION /12Z THURSDAY THROUGH MONDAY/...
A mix of conditions with higher cloud bases than earlier expected are
over much of the CWA and terminals this morning. Only some of the
lower IFR and low end MVFR clouds are found and they`re scattered at
the terminals attm. Expect these low clouds to continue to enter and
thicken from west to east as it trails the more widespread light rain
found over the eastern 2/3 of CWA. A trailing edge of showers is
currently located from near Lima towards Indianapolis and will see
more scattered light shower activity fill in ahead of it as it moves
east with the mean airmass.
MVFR vsbys with only lower chances of IFR cigs are being offered at
KDAY this early morning. If the IFR cigs look to expand across the
region, then this will need to be accounted by an amendment. Guidance
had been hitting pretty hard at these lower clouds centered around
this time. There are locations close by that are being hit by these
conditions but they aren`t at the airports attm. However it works,
MVFR cigs will be found by late morning, then lift in the afternoon
and scatter out after dark.
Clearing skies should be found overnight. Fog is being noted at LUK
and ILN, with a lesser hit at CVG and DAY tomorrow morning and
CMH/LCK with slightly higher vsbys as their clearing occurs the
latest.
Wind for all the terminals today will be nnw 5-7kt during the day
and drop under 3kt after 00Z.
OUTLOOK...areas of dense fog are possible before daybreak Friday.
