What's New / NOTES
6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

High pressure will keep dry air and mainly clear skies over the
region through the week. Temperatures will gradually warm as
the high moves slowly east.

Near term through tonight
Quiet weather as sprawling 1028mb surface high pressure just
southeast of the forecast area continues to drift toward the
atlantic coast. 18.12z kiln sounding was anomalously dry with
tropospheric pwat at about a third of an inch... Which is about
45% of normal. Very little, if any, clouds are expected today,
with abundant sunshine allowing for some locations to push
toward a 30-35f diurnal rise, which is typical for a very dry
mid-october day. Some southerly breeze on the backside of the
high will bring some modest winds to the open areas of eastern
in western oh, with lightest winds in the scioto valley and
northeast kentucky closer to the departing high.

Tonight, added some valley fog in the far east southeast parts
of the forecast area scioto valley and associated tribs and
this may need to be expanded in further updates. Approaching
very weak dry cold front may bring enough pressure gradient to
keep things stirred up but fcst soundings still showing a very
stable boundary layer after sunset. Expect min temps tonight to
be a little warmer thanks to said gradient, though some upper
30s will still be possible in the far east southeast portions of
the area, and much warmer west where winds and perhaps a few
clouds will keep temps in the 40s.

Short term Thursday
The surface ridge axis will shift a little east into Thursday
as a dry cold front pushes east southeast into the great lakes.

Again, only a few cirrus is expected, with perhaps a few-sct
cumulus clouds developing along ahead of the frontal boundary in
our far northwest late in the day Thursday.

Southwest to west winds ahead of the front along with sunshine
will boost highs into the lower 70s.

Long term Thursday night through Tuesday
Under an amplifying mid-level ridge over the eastern half of the
conus, a sprawling area of very dry surface high pressure will be
moving slowly east on Thursday night, still maintaining control of
the weather situation over the ohio valley for another couple days.

Aside from a very weak cold front stalling out (and then returning
north) in the northern ohio valley on Thursday night into Friday,
there will be little change in the overall pattern through Friday
night. Low-level warm advection, with gradually increasing 925mb
temps, will allow for Friday to be slightly warmer than Thursday.

As confidence has increased in a more amplified pattern on Saturday,
with deep-layer flow becoming more southerly over the ohio valley,
there is greater confidence as well in temperatures being warm for
the first day of the weekend. If the forecast for MAX temps in the
middle to upper 70s verifies, it will be about ten degrees above
normal. This looks to be the warmest day of the entire forecast

On Sunday, a sharp but narrow trough will begin its progression
eastward across the mississippi valley, eventually reaching the ohio
valley at some point between then and Monday. Model timing agreement
remains somewhat sub-par with this system, and the differences are
primarily focused around the interaction between the southern end of
the trough (which may form a cut-off low) and the strong jet stream
pushing east across the northern tier of states. Unfortunately, this
time frame remains in an unstable part of the forecast cycle, with
gfs ECMWF run-to-run consistency performing poorly.

With the above in mind, pops will be kept in the chance range until
this really gets locked in a little better. As of now, the greatest
precipitation chances appear to be during the Sunday night forecast
period, possibly continuing into Monday. Once the trough and its
associated cold front pass through the area, there appears to be
potential for a larger upper trough to move into the great lakes
late on Monday and into Tuesday, which should provide two things --
much cooler temperatures and continued chances for rain.

Aviation 15z Wednesday through Sunday
Surface high pressure will extend across the ohio valley
through the TAF period.

For early this morning, river valley fog will once again be a
concern at kluk. Fog should burn off by 14z.

Otherwise, mainly clear skies are expected through the period.

Winds will increase from the south between 5 and 10 knots by 16z
then diminish after 23z.

Outlook... No significant weather expected.

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.
