Synopsis
A warmer and more humid airmass will work into the region on
southerly winds as low pressure in the northern great lakes
region drapes a cold front southwest towards texas on Friday.

Showers and thunderstorms will be on the increase as this front
approaches the ohio valley and washes out early Saturday. The
passage of an upper level trough axis will shunt any available
moisture to the east Saturday evening, ending and thunderstorm
activity in the region.

Near term until 6 pm this evening
Increased temperatures from consshort for today closer to
guidance values. This would give high temperatures in the middle
to upper 80s. Winds have already started to gust and expect
increased wind gusts for this afternoon into the early evening
hours with some wind gusts upwards of 25 to 35 mph. These winds
will also help bring in the warmer temperatures. There will be
two primary areas of thunderstorm development today. The
southeast is expected to have some thunderstorm development
first and already see CU development on satellite. Additional
thunderstorms will form later and move into northwestern
portions of the forecast area. Cannot rule out an isolated
damaging wind gust with the thunderstorm activity today, but not
expecting widespread severe weather.

Short term 6 pm this evening through Sunday night
Storms will become more numerous on Friday and particularly
overnight as the cold front stretches out as it tries to pass
southeast but ultimately gets washed out over the CWA early
Saturday. High pressure builds in from the west and upper level
energy rotating through the larger scale trough will help shunt
any lingering moisture to the east for a rapid improvement and a
drier latter half of the weekend. Temperatures will never get
the benefit of the passage of a cold front and be near seasonal
normals, but dewpoints on Sunday will be in the lower 60s versus
the less comfortable upper 60s found through Saturday.

While some models are still keeping the boundary over the region
early enough on Sunday to consider some chance of showers or
isolated thunderstorm early in the day southeast of the i-71
corridor, current forecast has limited this even further in
favor of the high pressure in the upper midwest pushing in drier
air.

Long term Monday through Wednesday
We should then dry out Sunday night into Monday. However,
several mid level short waves will push east across the area
through mid week. This will lead to additional chances of
showers and thunderstorms at times through the remainder of the
long term period. Highs Tuesday and Wednesday will be in the mid
80s.

Aviation 14z Thursday through Monday
Expect cirrus blowoff from the convection out west to continue
to drift ewd today, keeping a bkn ceiling. Meanwhile, scattered
cu will develop later this morning as moisture increases in the
broad sly flow. Majority of the models keep convection to the
northwest of the region. A few of the cam's develop showers
across SE oh NE ky. Even if these develop the tafs should remain
dry. Sfc pressure gradient increases today, and will support
wind gusts of 20 to 25 kt.

The gusts should taper off with sunset around 00z this evening
and bkn CIGS from cirrus will continue overnight. Convection
should start to fire tomorrow morning, so added a vcsh to the
cvg extended taf.

Outlook... Thunderstorms possible at times from Friday into
Saturday night and again Monday.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
