Synopsis
Low pressure will maintain shower chances and cool temperatures
through mid week.

Near term until 6 pm this evening
Broad dry slot has essentially ended precipitation over most of
the region, save for a few showers as the upper level jet
strengthens across the ohio valley and a secondary cold front
approaches. Still think low chance pops cover the current
coverage.

Coverage should increase later this morning as the large upper
low pivots over the great lakes. Best focus will remain over
ohio where the cold pool and deeper moisture resides today. Dry
air will continue to be pulled into the upper trough, limiting
precip elsewhere. All being told, cooling aloft and cloud cover
should still limit high temperatures today - with values closest
to normal where peeks of Sun are possible over WV pa.

Short term 6 pm this evening through Friday
Upper trough over the eastern CONUS will continue to influence
our weather through Wednesday night, until its lifted
northeastward as the next shortwave digs over the northern
plains. At least low chances for precipitation were carried
through Thursday morning as the trough axis pivots across the
region and we resume wnw flow slight lake-trajectory. However,
building subsidence in the wake of the departing trough may
quickly end any chance for precip before temperatures are at
their coldest Wednesday night. Maintained a brief snow shower
mention in the forecast for the terrain as soundings still
indicate a small window with moisture depth just cold enough for
a few flakes.

Cold pool aloft and cloud cover will likely keep temperatures
5-10 degrees below average through Thursday, with some
moderation on Friday as brief upper level ridging southwest
flow resumes in advance of the next system.

Long term Friday night through Monday
Next trough will dig across the central CONUS and pivot toward
the region for the weekend. Models are generally handling the
scenario well, with a cold front expected Sat night Sunday.

Temperatures will likely start above average on Saturday in
strong warm advection and return to below average values by the
start of next week.

Aviation 08z Tuesday through Saturday
MVFR stratocu is expected for much of the day under an upper
trough and cold advection. Stratocu heights should return toVFR
levels by late afternoon with mixing.

A sufficiently tight pressure gradient should maintain gusty
s-sw winds.

Outlook
Upper troughing should maintain periodic restrictions through
early Thursday. Restrictions are likely with a Sat cold front.

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 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.
