Synopsis
High pressure will build over the upper midwest today and move
into the ohio valley tonight. As it moves east on Wednesday,
southerly flow will bring a warming trend to the region through
the end of the week. A cold front is expected to pass to the
southeast early on Saturday.

Near term until 6 pm this evening
The center of an area of surface high pressure is currently
centered in east-central illinois, drifting east-southeastward
over the rest of the day. The iln CWA will be on the
northeastern periphery of the high, with light wnw flow a the
surface, leading to little (if any) warm advection at the
surface. 850mb temperatures actually dropped overnight, and will
remain generally steady today -- so despite a day with
plentiful sunshine, MAX temps will likely be no warmer than
yesterday (possibly a degree or two cooler).

Previous discussion >
a few lingering showers in the southeast will exit the region
before daybreak.

High pressure will bring a clearing trend and one more day of
temperatures that are about 10 degrees below normal.

Short term 6 pm this evening through Friday night
As the high moves southeast tonight, return flow will bring
slightly warmer min temps tonight than this morning's lows,
still in the lower to middle 50s. After this, the warming trend
will begin with generally clear skies Wednesday and increasing
cloud cover from the northwest Wednesday night. Temperatures
here will be closest to normal, with another jump in
temperatures Thursday. Overnight lows Thursday night will warm
to around 70 and linger there until the next front crosses on
the weekend. Daytime highs Thursday and Friday will be in the
middle 80s most locations, upper 80s possible in the south and
southeast given more sunshine and a longer period of time with
southerly flow.

Thunderstorm chances will increase on Thursday, primarily
north of the i-70 corridor as a front drapes west to east
through northern ohio. The bulk of thunderstorm activity will
lie north of the CWA but some outlying storms may skirt the
northern quarter of the CWA during the day and overnight. By
Friday, the upper level shortwave sparking most of the
development will coincide with the surface boundary. This will
move form northwest to southeast overnight, with the frontal
system passing on Saturday. Storms that do develop will have a
higher propensity of heavy rainfall from Friday into Saturday.

Long term Saturday through Monday
Have sped up the progression of the cold front on Saturday, and
this is the time that has the highest incidence of thunderstorm
activity.

With a clearing push behind the cold front late Saturday,
models have trended drier for Sunday, before warm advection
begins to bring a chance of precipitation into the area again on
Monday.

Aviation 18z Tuesday through Sunday
With high pressure in place, generally tranquil conditions are
expected through the TAF period, withVFR conditions. Scattered
cumulus clouds (4kft-5kft) have developed today, and will
dissipate by evening. Wnw winds today will shift to the SW and
become much weaker overnight. Though the air mass is dry, some
fog is expected at kluk, but will keep the forecast in the
MVFR ifr range rather than lifr.

Tomorrow, winds will shift again to the south, and will increase
in strength to around 8-12 knots (gusts are possible at kday).

Clouds should be limited to cirrus and a slight chance of some
vfr cumulus development.

Outlook... Thunderstorms are possible at times from Thursday
through Saturday.

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.
