Synopsis
Showers and thunderstorms will increase in coverage tonight
into Thursday ahead of slow-moving cold front. Precipitation
chances will diminish by Friday as drier air moves in from the
north behind the departing cold front. Surface high pressure
will build into the great lakes Friday night and Saturday,
offering cooler and drier weather. The high will move to the new
england region by Sunday. A few isolated storms may be possible
by late Sunday afternoon along and south of the ohio river as
moisture begins to return north.

Near term until 6 pm this evening
For tonight, a S WV to our west will move east into the region
late, along with a slow-moving cold front dropping southeast
into northern indiana and northern ohio. Models are not offering
a consistent solution in terms of timing and possible
convective coverage. Convection may be ongoing to our
west southwest this evening, and may move into the region
overnight, but likely weakening as it does. Have only gone with
chance pops due to uncertainty of coverage and timing. Otherwise,
mostly clear skies this evening will give way to increasing
clouds due to upstream convective debris blow off and possible
lower level clouds developing late. Lows will range from the
upper 60s to near 70.

Short term 6 pm this evening through 6 pm Thursday
On Thursday, aforementioned S WV is expected to stretch and
shear, followed by more digging energy into the southern great
lakes by afternoon and evening. This will push the cold front
very slowly to the southeast. Some low level convergence in
response to some large scale broad ascent, along with the
potential for a weak wave or two of low pressure to develop
along the boundary, will likely bring some showers and
thunderstorms to the area along and ahead of the front. Will
continue to keep pops in the likely category until timing and
coverage become more certain among the cams. Moderate
instability is expected to develop ahead of the front across the
south, and with at least some moderate deep layer shear, a few
strong to severe storms may occur. Damaging winds would be the
primary severe weather threat. This is mentioned in the hwo. In
addition, with pwats over 2+ inches, locally heavy rain will be
possible. Clouds and pcpn will keep temperatures down, although
it will continue to be humid. Highs will range from the mid 70s
north to 80 to 85 south.

For Thursday night, the front will continue slowly south. The
far northern sections will begin to dry out while showers storms
move south and become scattered in nature overnight. Lows will
range from near 60 far north to the upper 60s along and south of
the ohio river.

Long term Thursday night through Wednesday
Extended period starts with the region post-frontal, as a cold
front is forecast to be located across southern kentucky. Some
scattered convection will be possible across the southern
portions of the fa. The convection will slowly work south during
the day. The region will experience cooler temperatures with
highs only in the mid to upper 70s. A few spots in northern
kentucky might hit 80. Drier dewpoints will begin to filter in
during the afternoon.

High pressure over the upper great lakes will build into the
region Friday night. It will bring cooler and drier air to the
region for Saturday, with highs between 75 and 80 degrees.

As the high slips off to the east on Sunday, temperatures will
begin to warm. Humidity will be on the increase Sunday, with the
gfs developing some QPF Sunday afternoon. The ECMWF and
canadian keep the region dry and the forecast leans towards the
drier solution.

Southerly flow for next week will bring humid and unstable air.

This will bring the possibility of scattered showers and
thunderstorms for the first half of the work week. Highs on
Monday will be in the lower 80s Monday and will rise to the mid
80s by Wednesday.

Aviation 19z Wednesday through Monday
Dry weather should prevail across the region this afternoon into
this evening as active weather systems remain to the west and
northwest. Stratus will continue to lift into sct-bknVFR
cumulus and then will dissipate by sunset or around 00z. Winds
will generally be from the west around 10 to 15 mph.

For tonight, embedded disturbance will move east into the
region, along with a slow-moving cold front dropping southeast
into northern indiana and northern ohio. Models are not
offering a consistent solution in terms of timing and possible
convective coverage. Convection may be ongoing to our
west southwest this evening, and may move into the region
overnight, but likely weakening as it does. Have just placed
vcsh at the terminals due to uncertainty of coverage and timing.

Models continue to suggest that lower level clouds may
eventually develop toward 12z. Am not ready to hit the ceilings
low yet at this time as some of this could be affected by some
models allowing for a period of precipitation and saturation.

Thus, have kept ceilings in the MVFR category and between 2000
and 2500 feet, but certainly it could be lower depending on
convective outcome. Some local MVFR visibilities may develop
overnight as well, particularly at kluk and kiln.

On Thursday, first embedded disturbance is expected to stretch
and shear, followed by more digging energy into the southern
great lakes by afternoon and evening. This will push the cold
front very slowly to the southeast. Some low level convergence
in response to some large scale broad ascent, along with the
potential for a weak wave or two of low pressure to develop
along the boundary, will likely bring some showers and
thunderstorms to the area along and ahead of the front. Have
placed predominate -shra and a vcts at the 30 hour kcvg terminal
at this time. The airmass will be very moist, so where more
robust showers storms occur, MVFR ifr conditions or lower can be
expected.

Outlook... MVFR ceilings possible Thursday night into Friday
morning. Thunderstorms possibly lingering into Friday.

Thunderstorms possible Monday.

Thunderstorms will remain possible at times through
Friday afternoon.

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.
