.SYNOPSIS...
Waves of low pressure will result in more rounds of showers and
storms, bringing the prospects for heavy rain and potential flooding
into the weekend.

&&

.NEAR TERM /UNTIL 6 AM FRIDAY MORNING/...
Widespread showers and some embedded thunderstorms will persist
through the overnight with locally heavy rain possible. Mesoscale
guidance suggests a bulk of the heaviest precipitation is likely to
fall from I-70 on south with the highest totals possibly near the
Ohio River through daybreak. Isolated rainfall totals upwards of 2
inches are likely across southern Ohio and northern Kentucky. Some
flooding issues may start to develop tonight given the high
rainfalls totals expected tonight falling on already saturated
ground. The main areas of concern will be smaller creaks and rivers
along with some isolated flash flood problems.

This rainfall is being driven by anomalously high PWATs overlapping
with strong ascent and frontogenesis along the nose of a nocturnally-
enhanced LLJ parked across southern Ohio/northern Kentucky. This
round of widespread rainfall will contribute to the flood risk
increasing through the end of the week.

&&

.SHORT TERM /6 AM FRIDAY MORNING THROUGH FRIDAY NIGHT/...
Friday morning, showers and some thunderstorms are likely ongoing,
especially closer to the Ohio River. Throughout the mid-morning and
into the afternoon, a deepening ridge will begin to push the better
low-level jet stream forcing northward. How the front and associated
rainfall evolves throughout the period is a bit uncertain as
convective/mesoscale processes offset the northward push of the
broader synoptic flow. Eventually, perhaps as late as Friday evening,
the synoptic flow prevails, especially farther to the west as surface
low pressure deepens over the mid Mississippi River Valley. New
convective development forms to the west of the local area, spreading
southeastward into the Ohio Valley Friday evening into Friday night.

If the convective processes can remain established into the
afternoon, warm and moist air attempting to move northward will
encounter surface outflow boundaries and/or the lingering front,
initiating additional thunderstorms. This situation would increase
the potential for localized flash flooding and heavier rainfall. For
now, the WPC DAY 2 ERO Slight Risk is appropriate, but a locally
higher threat may develop based on this scenario.

Severe threat Friday night remains marginal with the more rich
surface moisture and warm temperatures struggling to advect
northward along with meager mid-level lapse rates. So while plentiful
shear is present, the thermodynamic environment is not conducive for
surface based convection through the overnight.

By the close of the short term period, a corridor of thunderstorms is
likely to be occurring over the area, with uncertainty on the exact
placement. Due to the saturation of soils and elevated streams, flooding
and flash flooding will be a concern heading into Saturday morning.

&&

.LONG TERM /SATURDAY THROUGH THURSDAY/...
The surface boundary will be situated just off to our northwest
Saturday morning with our area mainly in the warm sector. The
boundary will begin to sag down across our area Saturday into
Saturday night as the final wave of low pressure moves east along it.
This will lead to one last round of decent rainfall, mainly Saturday
afternoon into Saturday night. It looks like 1 to 2 inches, with
locally high amounts may be possible with this last batch of pcpn.
This may represent the best chance for flooding/flash flooding
through this longer event, as streams will already be running high by
this point. We will likely end up with a decent temperature gradient
on Saturday with highs ranging from the mid 60s northwest to the low
80s in our far southeast.

The boundary will push off to our southeast through the day on
Sunday as an upper level trough settles in across the Great Lakes
region through mid week. This will lead to below normal temperatures
through the rest of the long term period, with the coolest day
looking to be on Tuesday when daytime highs will only be in the low
to mid 40s.

Some mid level short wave energy moving through the trough will lead
to some lower end chances for showers, particularly Monday afternoon
into Monday night and then again Wednesday night into Thursday.
Thermal profiles may be cool enough Monday night to allow for some
snow to mix in with the showers.

&&

.AVIATION /01Z FRIDAY THROUGH TUESDAY/...
Widespread showers and thunderstorms continue through the TAF
period. For this rest of this evening and overnight, showers and
some thunder is are forecast at all the sites. Lowering MVFR and IFR
ceilings accompany the rain. For Friday, showers and storms may be
more focused along and near the Ohio River with KCVG and KLUK being
primarily impacted through the day. MVFR and IFR ceilings persist
across the sites with the unsettled setup in place.

Light northerly winds develop overnight. Winds veer to the northeast
and eventually the east on Friday.

OUTLOOK...Periods of showers and thunderstorms will occur into
Sunday morning. This will result in MVFR/IFR conditions from time to
time.
