Synopsis
A warm front pushes in late Thursday, ahead of a system that
will cross Thursday night and Friday. High pressure builds in
for Sunday.

Near term /through Thursday/
As of 127 pm Wednesday...

clouds have been much slower to clear than previously thought.

However, they are now clearing, especially from the north and
west.

The clouds should continue to clear during the evening hours.

Clouds will then begin to increase across portions of the
mountains by late tonight, as winds turn easterly ahead of an
area of low pressure.

The low pressure system will continue to approach the area
Thursday, with a warm front expected to push into the region
from the southwest during the afternoon.

Expect precipitation chances will increase on Thursday.

However, the models differ about the onset of the precipitation
chances.

Latest 12 utc NAM suggests that much of the area should remain
dry with some low precipitation chances developing in the
mountains. Latest 12 utc GFS is much faster with precipitation
chances across much of our NE ky and SE oh counties by daybreak.

The precipitation chances will then spread across the remainder
of the area during the day.

Previous forecast indicated a trend which was a compromise of
these models and see no reason to make any wholesale changes to
that forecast.

Short term /Thursday night through Saturday night/
As of 330 am Wednesday...

active, but progressive pattern continues with a broad low
pressure system crossing Friday. System spacing is buffered by
a day or two on both sides. This tends to allow excess precip to
evacuate the area making water issues less likely. Stuck in a
pattern that keeps trekking systems' low pressure centers over
oh/wv, so healthy doses of precip continue with each system
keeping FFG low, but difficult to pull out specifics as slight
variations in track equate to a different forecast.

High pressure builds Saturday, but thick, residual low level
moisture may keep -dz around.

Long term /Sunday through Tuesday/
As of 330 am Wednesday...

more of the same, continued parade of similar type systems and
phasing with large breaks in between.

Aviation /18z Wednesday through Monday/
As of 127 pm Wednesday...

low clouds continue to erode with much of the region still
experiencing MVFR cigs. Conditions should rapidly improve with
most locations havingVFR conditions by 23 utc.

An area of low pressure will approach the area tonight. In
response, northeasterly winds will turning easterly then
southeasterly overnight. With the southeast flow, clouds and
maybe some light rain or drizzle should redevelop along the
eastern slopes tonight with some MVFR to ifr in the mountains.

As low pressure system continues to approach on Thursday, expect
chances for showers will spread across southeast ohio, northeast
kentucky and the western half of west virginia by 18 utc. There
could also be a few thunderstorms.

Much of the area will seeVFR conditions with MVFR to ifr
conditions still possible in the mountains
forecast confidence and alternate scenarios through 18z Thursday...

forecast confidence: medium.

Alternate scenarios: clouds could be slower to erode this
afternoon. Showers and ifr conditions could be more prevalent in
the mountains than thought.

Experimental table of flight category objectively shows consistency
of WFO forecast to available model information:
h = high: TAF consistent with all models or all but one model.

M = medium: TAF has varying level of consistency with models.

L = low: TAF inconsistent with all models or all but one model.

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.
