Synopsis
Above normal temperatures will persist across the ohio valley
through Monday ahead of a cold front. The cold front will bring
showers and thunderstorms on Tuesday, then drier and cooler air
moves in for the rest of the week.

Near term until 6 am Monday morning
Just some mid and high clouds across the region this evening.

But a disturbance in illinois will track into the area
overnight. This will bring some additional clouds and may result
in a few showers primarily across northern counties.

Temperatures will remain warm and have bumped up lows just a
bit.

Short term 6 am Monday morning through Monday night
Expectation is for any nocturnal upstream convection to have
dissipated by the time it would make it into the CWA early
Monday, although it's not out of the question lingering showers
make it into the far northwest cwa. Either way, some high
clouds will be left behind for Monday morning. More cumulus are
expected by afternoon as well, and therefore have started to
trend the sky forecast upward a little for Monday, and it's
possible that much of the CWA could wind up more partly cloudy
than mostly sunny for Monday. In addition, latest guidance
suggests the potential for convective development in the
afternoon early evening mainly across the northwest portion of
the cwa. Larger scale forcing is still best well northwest of
the cwa, but moisture looks better and models suggest sufficient
cape to generate a few cells as long as any capping erodes.

Maxima will rise into the upper 80s, perhaps even hitting 90 in
a few spots. Factoring in dewpoints in the mid 60s will yield
heat index values into the mid 90s on Monday.

Much of any convective activity on Monday would likely
dissipate after the Sun sets, but as a cold front approaches
will continue with very low pops across the northwest corner of
the CWA late at night.

Long term Tuesday through Sunday
The main focus for the long term period will be the potential for
severe weather and flash flooding on Tuesday. Thunderstorms will
begin to move into northwestern portions of the forecast area
Tuesday morning. In addition cannot rule out some isolated
convection along and just southeast of interstate 71 during the late
morning and into the afternoon hours. These storms will have a
damaging wind and hail potential.

As the line of storms across northwestern portions of the forecast
area move towards the southeast it will encounter a better
environment with higher, although not substantial, CAPE values.

Expect the main threat with the line to be damaging winds with
locations northwest of dayton having the lowest threat and a higher
threat along and just southeast of interstate 71. With the flow
orientation believe that the wind threat south of the ohio river
will be a little less, however isolated damaging winds will still be
possible. With the orientation of flow and the potential for the
multiple rounds of thunderstorms, flash flooding will also be a
concern generally southeast of interstate 71. The cold front will
move through Tuesday night. This will be followed by cooler and
drier conditions for several days.

With good CAA Wednesday and Thursday increased cloud cover
substantially with CU expected to develop during the day on both of
these days. Expect less cloud cover on Friday and Saturday as we
lose the caa. Temperatures Wednesday through Saturday will
generally be in the 70s across most locations.

Another system begins to approach for Sunday so there will be an
increase in cloud cover and precipitation chances will begin to move
back into the region. Temperatures will also be slightly warmer on
Sunday with waa.

Aviation 02z Monday through Friday
As a disturbance pushes into and through the area between 06z
and 15z there will be a scattered to broken deck around 5-6kft
and possibly a few showers. This disturbance will likely
minimize visibility restrictions, although there is some
possibility at kluk. Once this disturbance passes, expect few to
scattered cumulus to remain through the rest of the TAF period
with cirrus over the top. Winds will be light tonight and become
south southwest up to 10 kt during the day.

Outlook... Thunderstorms are likely Tuesday into Tuesday
evening.

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.
