An upper level disturbance will move through the region on
Saturday bringing showers and thunderstorms to the region. High
pressure will then be in place for Sunday and Monday. A cold
front will approach the region on Tuesday bringing a return of
precipitation to the area.

Near term until 6 am Saturday morning
A cold front will approach the region from the west tonight. Mid
clouds currently over mo il will stream into the ohio valley
overnight, and showers with a few thunderstorms will be possible
before daybreak in the northwest underneath a digging h5
trough. Showers and thunderstorms will be advected in from the
west, so there should be ample upstream notice of their specific
time of arrival in the region. A number of models are dry with
this feature, so a hedge to lower pops may be necessary with
future updates. Increased min temps by a degree or two given the
expected cloud cover increasing overnight.

Short term 6 am Saturday morning through Saturday night
A decent upper level disturbance will move through the region on
Saturday. The limiting factor with this system will be that
there is not a lot of moisture with this system, however given
the support with this system and model agreement, increased
precipitation chances across northern portions of the region.

Precipitation chances will be less along and south of the ohio
river. It looks like there will be an initial round of
precipitation that works through the area Saturday morning,
then there will also be the potential for additional
thunderstorm development across extreme eastern portions of the
forecast area with daytime heating during the afternoon. There
is some instability during the day therefore went with a chance
thunderstorm mention as well. Cannot rule out an isolated
damaging wind gust or large hail across extreme eastern portions
of the forecast area with the afternoon development, however
the more likely scenario would be small hail and some gusty

Went close to conshort for highs which is close to the cool
side of guidance values. With extensive cloud cover expected
with this system and the timing of this system, believe that
most locations will be limited to the upper 70s to low 80s.

Locations along and south of the ohio river where there will be
less cloud cover and precipitation will see potentially higher
temperatures around the middle 80s.

Winds will pick up during the afternoon as the system begins to
pass through and some wind gusts around 20 mph outside of
thunderstorms will again be possible. Winds will quickly
diminish during the evening hours and cloud cover will begin to
decrease. This will allow for temperatures to drop down into the
upper 50s to low 60s across the area.

Long term Sunday through Friday
Models are in good agreement that a surface high pressure will be
centered over the region Sunday morning. This will bring mostly
sunny skies and seasonable temperatures in the mid to upper 80s.

The center of the high will pull east of the region Sunday night,
allowing a little of a return flow for Monday eclipse day. There
should be some cumulus development in this flow, but the clouds
shouldn't spoil the viewing. Kept the forecast dry, but there is a
model or two that pops a shower on Monday.

A more substantial chance of rain will develop Tuesday into Tuesday
night as cold front swings through the great lakes and ohio valley
ahead of a strong h5 S w. 12z models are a little slower with the
system on Tuesday, so adjusted the timing back. The best chance of
thunderstorms will looks like Tuesday afternoon into Tuesday night.

Upped pops to likely to cover this system.

Behind the front Wednesday, a cooler and drier airmass will begin to
settle in for the later half of the week.

Aviation 00z Saturday through Wednesday
A weak surface cold front combined with a stronger upper level
digging trough will bring the threat of showers and possibly a
few thunderstorms to the region and TAF sites Saturday morning.

Several models are showing this feature to cross through the
area dry, so the forecast has hedged towards a narrower timing
of showers and lowered the chances slightly. Even if this comes
out to be an improper swing of the forecast, conditions outside
of any shower activity will beVFR through the forecast period.

Showers and storms that do develop tomorrow morning will likely
only see an ever so brief reduction with CIGS and vsbys in the
MVFR category.

Sky cover will rapidly clear tomorrow afternoon as northwest
winds usher in drier air and downward motion on the back side of
the upper level trough helps to dissipate any lingering cloud

Outlook... Thunderstorms are possible on Tuesday.

These have not been checked for accuracy and in many cases have not even been read by anyone associated with I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at 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.
