Ahead of slow-moving cold front, thunderstorm activity will
increase beginning late tonight. After is passes Friday night,
rain chances will diminish as high pressure builds into the
great lakes through Saturday. Cooler and drier weather will be
found as the high moves to the new england region Sunday.
Near term until 6 am Thursday morning
Convection well SW of the CWA will continue to push SE and out
of the area of concern this evening. Models do not seem to have
a solid handle on how wx is going to play out overnight but a
reasonable solution can be gleaned, which led to the general paring
down of pops overnight. Two areas of concern will see an
increased pop later towards daybreak. One in the northwest along
the front, the second rolling east over the southern section of
the CWA with mid level S W energy riding east ahead of the upper
Observations did not seem to support any convection later this
evening as it just wasn't occurring upstream to work in. Will
continue to monitor and likely pare back some more with
subsequent updates, or possibly increase the probability later
overnight if the models align on a similar result.
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 am Thursday morning through Thursday night
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 Friday 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
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 00z Thursday through Monday
Generally clear skies with a few cirrus clouds will see
increasing clouds from the northwest given upstream activity
working in. If this does not affect the region until late, lower
stratus is favored tonight.
Showers and thunderstorms will become increasingly likely
beginning late tonight in the west, a little lull in the day,
then more likely thunderstorm activity in the afternoon with a
cold frontal passage. Generally expectingVFR conditions but
some MVFR vsbys in fog are possible between midnight and
daybreak, then shower and some thunderstorm activity will be
expected, with similar MVFR CIGS where they occur.
Shortwave energy may precede the frontal passage and limit the
amount of stronger storms in the afternoon. There is a lot of
variability in how the models are diagnosing the atmosphere
tonight and tomorrow, leading to a low confidence forecast in
timing, hence the liberal usage of vcsh and vcts.
Outlook... MVFR ceilings possible Thursday night with some
lingering thunderstorms. Thunderstorms possible Monday.

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.
