Special Weather Statement, NWS Wilmington, OH

Area Forecast Discussion
National Weather Service Wilmington OH
815 PM EDT Sun Jul 16 2017

.SYNOPSIS...
A cold front dropping south through the Great Lakes will bring
a slight chance of showers and thunderstorms to the region
tonight into the early part of the the work week. Temperatures
will be near normal for the next couple of days, then a gradual
increase in heat and humidity is expected going into the second
half of the work week.

&&

.NEAR TERM /UNTIL 6 AM MONDAY MORNING/...
Scattered convection has developed in an axis of moisture
convergence along a cold front and moved into west central Ohio.
Near term guidance suggests that this activity will persist
through the evening while only making slight southward progress
as the boundary weakens. Have increased PoPs in the northwest
counties this evening and then allowed it to fizzle overnight.
Looks like there will be river valley fog again.

&&

.SHORT TERM /6 AM MONDAY MORNING THROUGH MONDAY NIGHT/...
By Monday morning the upper s/w will be east of the region, but
a sfc trof will be lingering across the ern zones. As the
atmosphere heats up, there should be enough convergence for some
scattered cells to pop. Chance PoPs look sufficient at this
time. Highs will range from around 80 in the nw, to the mid 80s
in the south.

A few storms could linger into the evening hours, but overall
expect Monday night be dry, with lows in the lower to mid 60s.

&&

.LONG TERM /TUESDAY THROUGH SUNDAY/...
The long term will be a summertime pattern with warm and humid
conditions for much of the time period.  Tuesday will be the coolest
day with high temperatures expected to be in the low to mid 80s. A
diffuse washed out frontal boundary will be in place at the start of
the long term therefore some patchy fog will be possible Tuesday
morning.

With a weak frontal boundary in the vicinity Tuesday afternoon
cannot rule out an isolated shower or storm along and south of the
Ohio River.  Moisture should be limited however and remain primarily
south of the region.  Due to this limited precipitation chances to a
slight chance.

The heat and humidity will be on the increase for Wednesday with
southwesterly flow.  Temperatures Wednesday through Sunday are
expected to generally be in the middle 80s to low 90s.  Heat index
values across portions of the area will be in the middle 90s to
around 100.  With some uncertainty with clouds and convection will
leave heat index values out of the hazardous weather outlook at this
time, however will continue to monitor as the week progresses.

The area will be in northwest flow aloft for Wednesday through
Saturday.  During this time expect multiple disturbances to work
down into the region in the northwest flow.  Although there will be
off and on chances for precipitation, Friday night looks to be the
best chance for shower and thunderstorm activity.  Additional
thunderstorm chances will be present for Sunday with unstable
airmass.

&&

.AVIATION /00Z MONDAY THROUGH FRIDAY/...
Convection northwest of the region will likely diminish before
reaching KDAY. Otherwise VFR will prevail through the early part
of the TAF period. A weak boundary will sag to near KDAY to
KCMH. Along and north of this it appears low ceilings will
develop. Enough uncertainty to keep those ceilings out of the
TAFs at this time. Most locations will likely see visibility
restrictions develop late tonight. KLUK will be LIFR in river
valley fog. Otherwise only expect MVFR restrictions.
Visibilities will improve after 12Z. Additional showers and
thunderstorms may develop in the afternoon and affect
KCVG/LUK/KILN.

OUTLOOK...Thunderstorms are possible Friday.
