Area Forecast Discussion
National Weather Service Wilmington OH
1108 AM EDT Fri Jul 7 2017

.SYNOPSIS...
A cold front from the northwest will bring the likelihood for
showers and thunderstorms today into tonight. High pressure will
follow the front, providing dry weather for Saturday and
Sunday. Another cold front is forecast to sag south from the
Great Lakes on Monday and Tuesday, with more showers and
thunderstorms possible.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
Severe Thunderstorm Watch 401 in effect until 5 PM EDT this
afternoon across central Ohio and Indiana.

Main update to morning package was to the PoPs as showers and
thunderstorms have already developed across northern Indiana and
are pushing southeast. Earlier this morning another complex of
showers and thunderstorms pushed east across the area and left a
outflow just southeast of Columbus (as seen on GOES R). The
showers and thunderstorms currently in Indiana will likely dive
southeast and follow the old out flow. ML Cape out ahead of the
showers and thunderstorms are around 1500 to 2500 J/kg with
around 20 to 30 kts of SFC - 3km and SFC - 6km shear. The better
shear remains further northwest near the upper level support.
Latest high res guidance has struggled catching on with the
latest trends with the HRRRX seeming to try and catch on.
Current thinking is for current complex of showers and
thunderstorms over northern Indiana to dive southeast and
weaken. More redevelopment is then forecasted on the western
edge and is forecasted to push south towards Cincinnati this
afternoon into evening.

The surface cold front will then trail behind this evening.
Secondary development along the cold front looks less likely
given the convection that looks likely to have occurred out
ahead of the front. New zones already out.

Prev Discussion->
Patchy fog has developed over ground that is moist after recent
rainfall. Have issued SPS for reduced visibilities through 9
am. Though visibilities seem to be improving a bit as drier air
works in from the west, will continue to monitor for possible
NPW.

Once fog burns off by mid morning, the chance for showers and
thunderstorms will increase with daytime heating, especially
this afternoon as a cold front approaches from the northwest.

As thunderstorms become likely by late afternoon, some storms
could reach severe limits in an environment containing moderate
instability and ample wind fields. Severe weather may be more
prevalent in northern locations where stronger winds will
further enhance storm organization.

High temperatures in the mid 80s will be around normal.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SATURDAY/...
Cold front will be over the southern part of the CWA this
evening, before traveling across the Ohio River tonight.
Thunderstorms, some possibly severe, will continue early
tonight in southern counties, until daytime instability wanes,
and frontal forcing diminishes.

For Saturday, an area of high pressure is forecast to move in on
a northwest flow aloft, bringing mostly sunny and dry weather.

Cold advection will allow below normal highs in the upper 70s.

&&

.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...
Northwest flow with surface high pressure building across the region
Sunday. This high will provide dry weather with highs generally in
the lower 80s.

Southerly flow on the back side of the high will result in an
increase in moisture. Will show chance pops for thunderstorms Monday
with the best chance across the north, closer to an east-west
oriented frontal boundary. Temperatures will be a little warmer with
highs Monday from the lower 80s north to the mid 80s south.

The chance for showers and thunderstorms will increase Tuesday and
Wednesday as the front drops south across the region toward mid
week. Highs Tuesday and Wednesday will be generally in the mid 80s.
Model solutions differ on timing but show a wave pushing through the
Great Lakes Thursday and the front slipping south of the Ohio River
by the end of the week. Uncertainty increases due to model solution
spread but this front will keep the threat of showers and
thunderstorms in the forecast. Temperatures look to continue close
to normal with highs generally in the mid 80s Thursday and
Friday.

&&

.AVIATION /15Z FRIDAY THROUGH TUESDAY/...
FG/BR that formed in humid air following rainfall has begun to
decrease. Wind above calm advecting somewhat drier air from the
west is mitigating the situation.

Once lingering BR burns off by around 14z, expect VFR through
the daylight hours. However, thunderstorms are forecast to
develop ahead of a cold front, affecting TAF sites mainly late
in the afternoon and into the evening as the front travels
across TAF sites. Winds from the west will gust close to 20
knots during the afternoon.

Convection will diminish tonight as the front drops south of TAF
sites and daytime heating decreases. BR may reduce visibilities
early Saturday morning in residual low level moisture behind
the front. Expect VFR at CVG after 12z Saturday with northwest
winds.

OUTLOOK...No significant weather is expected.
