Synopsis
Unsettled weather will return for the remainder of the week as
an upper-level disturbance moves slowly across the ohio valley.

Near term through Wednesday night
An approaching shortwave will result in light and scattered
shower development this evening south of i-70... With coverage
gradually spreading further north as the night progresses and
the very dry lower levels begin to saturate.

Scattered precipitation remains a possibility through Wednesday
as a deep upper trough continues east towards the forecast
area... Becoming more widespread by early Wednesday evening as
moisture increase further and the upper trough axis moves moves
over the ohio river valley providing more favorable dynamics.

Temperature on Wed will see little difference to those today, as
insolation may be limited by clouds but cloud cover overnight
will limit radiational cooling effects and provide a warmer
initial state.

Short term Thursday through Friday night
A strong upper-level low pressure system will meander from the
central plains into the ohio valley late in the week, leading to
a persistent active weather pattern through the end of the week.

Although air temperature will decrease slightly into the upper
60s owing to cloud cover, cold air aloft associated with this
low is expected to provide a modest increase in instability thu
and fri, which will increase the chances for more-vigorous
convection, especially as the low-level wind flow veers to more
of a wly component.

Long term Saturday through Tuesday
The slow-moving upper low will advance newd by Friday night,
and an upper ridge will take hold briefly. Quiescent conditions
will be relatively short-lived as the mid-level ridge axis
progresses quickly ewd. The net effect will be a return to deep
swly flow aloft for the weekend. This will bring gulf moisture
toward the area again, resulting in increasing temperature and
humidity and increasing convective chances at least through
memorial day.

Aviation 00z Wednesday through Sunday
Vfr conditions are expected through the evening as only high
clouds build into the area. The coastal low pressure system will
begin to spread light rain into the area tonight, but no
visibility restrictions are expected. Ceilings may begin to fall
to near MVFR near daybreak Wednesday.

Wind will remain light and from the east-southeast through the
period.

Outlook
Restrictions are likely late Wed thru Thu and are possible thu
night thru Sat with crossing low pressure.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
