...FLASH FLOOD WATCH IS CANCELLED...

The Flash Flood Watch for portions of Indiana, Northern Kentucky,
and Ohio has been cancelled. The threat for additional flash
flooding has ended. However, high water lingers from earlier heavy
rainfall.

What forecasters said that day

The local office's own words before this flash flood watch went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Wilmington, OH wrote its last area forecast discussion before this flash flood watch went out at Apr 28, 10:30 AM EDT, 1 hour 14 minutes earlier.

Area forecast discussion, Apr 28, 10:30 AM EDT, 1 hour 14 minutes before
Area Forecast Discussion
National Weather Service Wilmington OH
1030 AM EDT Fri Apr 28 2017

.SYNOPSIS...
High pressure will move east early today. A frontal boundary will
develop into the region this afternoon and linger near the area
into Sunday, causing unsettled weather through the weekend. Cooler
temperatures will filter in behind the front next week.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
A developing warm front will lift north across the Tennessee
Valley through this afternoon, possibly pushing north into
southern portions of our fa through this evening. There remains
some uncertainty among the models as to how far north this
boundary will make it and as a result where the heavy rain and
severe threat will set up later today into tonight.

Along and south of the boundary, good instability will develop
through this afternoon. A weak mid level short wave will move
east across the Ohio Valley this afternoon and this may help
initiate convection along the boundary. With good shear
profiles along the boundary, severe storms with some rotators
would be possible later this afternoon into this evening along
and south of the boundary with training storms and potential
flash flooding too. Farther to the north of the boundary, the
storms will be more elevated, leading to primarily a hail
threat heading into this evening.

The synoptic models are generally farther north than the
higher-res cams, with the last several runs of the HRRR keeping
the focus generally south of our FA. It does appear the the
highest severe threat will be south of the Ohio River, possibly
over into far south central Ohio. This is also the area that
would seem most prone to flash flooding but with the synoptic
models much farther north with their swath of heavy rain later
tonight, there remains quite a bit of uncertainty as to where
the heaviest rain threat will be. We may eventually need a
flash flood watch across parts of the area but prefer to see
what the 12Z runs show to see if the flood threat can be more
fine tuned.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SATURDAY/...
Warm front nearly parallel to the upper flow will remain in the
region tonight, lifting to Northwest Ohio. As isentropic lift
intensifies under a strengthening upper jet, showers will become
widespread in northwestern locations, while showers will be
much less prevalent in the southeast farther from the boundary.
Convective development will be enhanced by ample short wave
energy and moisture advection traveling along the slow moving
boundary. Thunderstorms will be possible in a zone of elevated
CAPE near the front, and some storms may reach severe limits.
Models indicate favorable wind shear profiles above an
inversion layer that suggest large hail as the main threat.

Showers and a few thunderstorms will continue mainly across
northern locations on Saturday. Activity should show a
diminishing trend by Saturday evening when the frontal forcing
is forecast to lift toward Lake Erie.

With the area mainly in the warm sector, temperatures will
exhibit a warming trend. Highs will range from the upper 60s
north, up to the mid 80s south.

&&

.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...
Warm and moist southwest flow aloft will lead to an active weather
pattern this weekend into early next week. Surface warm front to
lift north through ILN/s FA Saturday night. Best forcing associated
with low level jet/instability and moisture to our west. Therefore,
will limit pops to chance category with the best chance northwest.

Upper level low to develop over the Central Plains and then lift
northeast into the Upper MS Vly Monday. On Sunday the best forcing
and lift to our west with ILN/s FA in the warm sector. Will limit
pops to chance across the western counties. Temperatures look to be
10 to 15 degrees above normal, with highs Sunday ranging from 80
northwest to the upper 80s southeast.

Model solutions generally similar with strong cold front pushing
east into ILN/s western counties by 12Z Monday and then sweeping
east across the FA early. Due to strong front expect widespread
convection to develop but instability is marginal. PW/s increase to
above 1.5 inches, so heavy rain rates will be likely but
precipitation will be progressive with front east of ILN/s by early
afternoon. 850 mb winds of 45-50 kts will persist in the wake of the
front in CAA pattern. Momentum transfer technique suggest surface
wind gusts of 40 mph likely. Will continue to highlight this threat
in the HWO product. Temperatures will be turn cooler with highs
Monday from the mid 60s west to the mid 70s east.

Deep upper level low to track ene through the Great Lakes Monday
into Tuesday. Will keep chance pops of a shower across the north
into early Tuesday. Temperatures will be a little below normal, with
highs ranging from near 60 northwest to the upper 60s southeast.

Mid/upper level flow backs with moisture increasing Wednesday acrs
the far south and then across the entire FA Thursday. Model
solutions differ on moisture placement Thursday with GFS keeping
main moisture east. Have favored a Canadian/Ecmwf blend with best
pops in the east Thursday but spreading pcpn chances across the
entire area. Wednesday's highs look to range from the lower 60s
northwest to the upper 60s southeast. Thursday looks even cooler
with highs of 60 to 65.

&&

.AVIATION /14Z FRIDAY THROUGH TUESDAY/...
Period starts dry under weak high pressure giving mainly mid
and high clouds. BR will reduce visibility at LCK early in the
forecast, with MVFR ceilings at LCK and CMH. Once early morning
BR and low clouds dissipate, conditions will then deteriorate
slowly as a warm front develops. Clouds will thicken and lower
while ceilings remain VFR through the afternoon and evening,
and showers may occur by evening at western sites in increasing
moisture and lift associated with the warm front. MVFR
conditions may eventually accompany the showers late in the
forecast period as the boundary layer nears saturation. Added
VCTS to all TAFs, with further refinement likely in later
forecasts. Surface winds from the southeast will stay under 10
knots during the early part of the forecast. Speeds around 10
knots out of the south are expected later in the forecast with
the showers. Wind shear is expected to develop for a few hours
late in the forecast.

OUTLOOK...MVFR ceilings and visibilities with a chance of
thunderstorms are possible Saturday, Sunday night and Monday.
Wind gusts to 35 kt possible Sunday into Tuesday.
