After an isolated evening shower, surface high pressure will
bring dry weather and cool temperatures tonight. An upper level
trough swinging through the great lakes will bring a chance of
showers and thunderstorms Monday afternoon into early Tuesday.

High pressure will provide dry weather at midweek with
increasing precipitation chances toward the end of the week as
temperatures warm to near normal.

Near term until 6 am Monday morning
Pronounced troughing with embedded disturbances rotating about
the larger-scale low continues across the great lakes and ohio
valley regions. Regional obs indicated that the very weak
surface boundary that had provided initiation for isolated
showers earlier has since moved to approximately parallel to
the ohio river. The showers were diurnally-enhanced and with
sufficient significant dry air throughout the column as sampled
by the kiln 00z sounding do not expect much in the way of
additional redevelopment through the near term period. As such,
have kept the fcst dry for all areas.

Behind this frontal boundary, a very weakly-defined broad surface
high pressure will build into the fa, allowing for light winds
and mainly clear skies through the overnight period. Some
scattered ac across the north will slowly dissipate through the
near term period, with many locations beginning the day on
Monday with clear mostly clear skies.

With relatively dry air in place and mainly clear skies,
another unseasonably cool night is in store for the fa, with
lows expected to bottom out in the low mid 50s area-wide.

Short term 6 am Monday morning through Monday night
Next mid level shortwave to drop southeast, sharpening up the mean
trof over the region Monday night. 25-30kt low level jet, along
with marginal instability may lead to a few rain showers or
isold thunderstorms into the west Monday afternoon. Will limit
pops to chance category. Temperatures look to be around 10
degrees below normal with highs Monday in the lower and middle

Expect this precipitation to drop southeast across iln S fa Monday
night ahead of a surface cold front. Thunder chances will
diminish as very weak instby decreases. Cool temperatures to
drop to lows in the lower and middle 50s Monday night.

Long term Tuesday through Sunday
On Tuesday morning, large-scale troughing will remain in place over
the eastern half of the conus, with a relatively dry air mass in
place from the upper ohio valley through the mid-atlantic. Attention
over the middle ohio valley will be focused on a shortwave trough,
moving ese through the overall flow. The axis of this trough will
likely not quite be cleared through the iln CWA by 12z Tuesday, with
some chance of showers remaining in place near the ohio river and
lower scioto valley through the morning. By afternoon, with
subsidence behind the shortwave, high pressure at the surface will
begin to take hold over the region. This will be too late to allow a
significant rise in temperatures, with below normal conditions
expected, especially in central ohio.

Dry high pressure is expected to remain in control of the weather
from late Tuesday through early Thursday, influencing conditions
through the middle part of the week. With a turning of winds to the
south on Wednesday, a more appreciable warmup will begin, with
temperatures returning to the 80s.

As a more progressive pattern begins to set up for Thursday and
beyond, model differences become more pronounced, leading to lower
confidence -- especially in precipitation timing near the end of the
week and into the weekend. There is agreement that a frontal zone
will set up east-to-west across the southern great lakes beginning
early Thursday, with the iln CWA in the warm sector within solid
deep-layer southwesterly flow. As convection develops at the north
end of this warm sector, and along the frontal area, there will
eventually be some propagation downstream which should impact the
iln CWA -- likely beginning on Thursday afternoon, and then again as
additional waves of precipitation occur going into Friday. How much
of the CWA remains capped is a question, as is the exact position of
the front. However, model runs have trended a little southward with
precipitation chances, increasing the probability for storms in the
iln CWA on Thursday and Friday (especially in the northern half of
the cwa). Pops have been increased slightly through this time
period, but with little change to temperatures, as there is
confidence in continued southwesterly flow through the period. In
addition, with ample instability and at least somewhat favorable
deep-layer shear, some strong to severe storms could be possible on
Thursday and Friday.

Differences in the evolution of an upstream trough going into the
weekend will preclude more than very low confidence in the forecast
Saturday into Sunday.

Aviation 02z Monday through Friday
Diurnally-drivenVFR CU coverage will decrease early in the taf
period, yielding mainly clear skies for the overnight period.

Gusty wnw winds will also subside towards sunset, with light
winds of around 5kts expected past 01-02z through mid-morning

With the wind not expected to go completely calm, and the
presence of quite a bit of dry air in the low levels, do think
that vsby restrictions will be difficult to come by at kluk.

Past 18z Monday, increased moisture ahead of an upper-level S w
and a weakly-defined surface frontal boundary will allow for a
vfr deck to gradually overspread the terminals towards the end
of the TAF period. Although quite a bit of dry air will remain
in the lower levels, there should be enough lift associated with
the aforementioned features to generate isolated to scattered
light shra after 18-21z. Although coverage will likely remain
scattered at best, expect that activity will shift south east
through the area towards the end of the period as the front
progresses southward, eventually affecting kcvg and kluk as
well. Have held off on inclusion of a vc for now at these
terminals until placement and timing becomes a bit more focused.

Altho instby will remain quite limited, cannot completely rule
out a TS with aft eve activity Monday. This being said, have
omitted from tafs at this time until placement and coverage
becomes better defined.

Wnw winds will increase to around 10 to 12kts during the day on
Monday, with a few gusts to 20kts possible.

Outlook... Showers and thunderstorms are possible Thursday and

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.
