Area Forecast Discussion
National Weather Service Wilmington OH
145 AM EDT Thu Jun 15 2017

.SYNOPSIS...
A warm and moist airmass will lead to an unsettled weather
pattern through the weekend. A drier and cooler airmass will
settle into the area early next week.

&&

.NEAR TERM /UNTIL 6 AM THIS MORNING/...
Line of showers and thunderstorms was moving into east-central
Indiana at 00Z. Just within the past hour or so, have observed
significantly less lightning and this adds support that this
line is weakening. Still, for at least a couple more hours,
there is the risk for strong gusty winds affecting areas of
east-central Indiana/far western Ohio. Then the risk will
diminish by late evening as suggested by most guidance,
although remnant showers may extend all the way toward central
Ohio by midnight.

Thereafter, models including high resolution guidance have
struggled with the potential for additional convection
overnight. There exists considerably higher uncertainty than
usual for a first period forecast. In this warm/moist
environment and with small scale boundaries lurking, certainly
can't rule out the risk for overnight convection (am already
seeing some new development in south central Indiana that will
likely affect our southwest CWA), however am leaning toward the
idea that any stronger/more widespread convection that develops
for the overnight would remain to the southwest of the CWA as
some of the most recent HRRR runs are suggesting.

&&

.SHORT TERM /6 AM THIS MORNING THROUGH 6 PM FRIDAY/...
Although the evolution of scattered activity in the near term
period has a degree of uncertainty to it, the consensus on
Thursday's activity is ironically a bit more focused.

Latest guidance has trended a bit slower with the weakly-defined
cold front expected to progress from west to east through the FA
during the short term period before it inevitably washes out
somewhere in the Ohio Valley. As such, trended PoPs a bit slower
for Thursday late afternoon and evening.

Destabilization will occur through the afternoon and evening
and convection will eventually develop during the heating of the
day before slowly progressing eastward through the evening. With
continued high PWATs in excess of 1.5," pockets of heavy rain,
and a corresponding localized flooding threat, will be possible.
Strongest activity will also yield a threat for locally
damaging winds. Will continue to highlight this potential in the
HWO.

With a bit less cloud cover expected through the first part of
the day on Thursday, temperatures may nudge up into the upper
80s in a few spots. Have trended highs several degrees above
guidance to account for this potential.

Drier conditions will return Thursday night as slightly drier
air moves in and best forcing most east of the FA. Slightly
cooler temperatures are expected, with lows generally in the
mid/upper 60s.

&&

.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
The immediate long term period will feature a quasi-westerly flow
pattern aloft with embedded weak disturbances rippling through this
flow from time to time Friday into Saturday. Timing of these
disturbances is somewhat problematic and whether it will coincide
with max diurnal instability. As such, will maintain a low threat
for showers/storms during this period. It will remain warm and humid
both days with highs in the upper 80s to near 90 and lows in the 60s
to around 70.

It still looks like a bona fide mid level trough will be poised to
traverse the Great Lakes and Ohio Valley Sunday into Monday. A cold
front associated with this trough will interact with a moist and
unstable airmass to bring the highest confidence/coverage for
showers/thunderstorms, particularly Sunday into Sunday night. Will
continue with likely PoPs. It will be warm again on Sunday with
highs in the mid and upper 80s.

We should begin to dry out on Monday as the front moves east.
Surface high pressure is forecast to build into the Ohio Valley
Monday night, moving east on Tuesday. Temperatures will cool back
down into the upper 70s and lower 80s with lows in the 60s.

A weak front may swing into the region on a northwest flow Tuesday
night into Wednesday, bringing the next chance for showers and
thunderstorms. Temperatures will be near seasonal normals.

&&

.AVIATION /06Z THURSDAY THROUGH MONDAY/...
Showers and thunderstorms are continuing to develop across
southern Indiana and weaken as they push east toward our area.
This is along the nose of a weak low level jet that is forecast
to shift slowly east through the pre dawn hours. As a result,
think we will continue to see this activity work slowly east
toward our western TAF sites, with the highest probability of
affecting affecting KCVG/KLUK through daybreak.

Models are trying to show an overall decreasing trend in
coverage through the day today. However, with a warm and moist
airmass in place, short wave energy pushing east across our
area and several remnant boundaries, think we will see at least
some scattered thunderstorm development later this morning and
into this afternoon. Will cover this threat with a VCTS. Any
activity should taper off through late afternoon as the short
wave moves east of our area.

OUTLOOK...Thunderstorms are possible Saturday through Sunday.
