Update
For 12z aviation discussion.

Discussion
Another chilly morning across the mid state this morning with
current readings ranging from the upper 30s to mid 40s. Some
cirrus that moved over the area is shifting east, with goes-16
nighttime microphysics imagery as well as surface observations
showing patchy fog along most area rivers and lakes. This fog
which may be locally dense in some areas will continue through
14z before lifting, very similar to yesterday. Also added mention
of patchy frost to parts of the upper cumberland where
temperatures are coolest.

Otherwise, forecast remains straightforward through Saturday with
high pressure over the eastern CONUS bringing us spectacular and
dry fall weather. Although a gradual warmup is anticipated each
day, nights will remain cool with lows in the 40s and 50s with
highs only in the 60s and 70s. Have kept temps generally near a
blend of MOS guidance with minor tweaks here and there. Patchy
fog is likely along rivers and lakes once again the next couple of
nights as water temperatures remain very warm in the 70s, skies
will be mostly clear, winds will be light, and dewpoint
depressions low.

Unfortunately, the enjoyable model consensus experienced 24 hours
ago has disappeared this cycle as 00z global models are
struggling with the evolution of the large upper trough expected
to dig southward into the eastern CONUS early next week. The gfs
attempts to break off part of the upper trough into a cut off low
which would linger precip chances across middle tennessee into mid
week, while the euro remains much more progressive getting the
bulk of precip out of the area by late Monday. Given the strength
of the 100+ knot h5 jet digging into the base of the trough early
next week, a more progressive solution like the ECMWF seems more
reasonable at this point. Thus will have highest pops from Sunday
afternoon through Monday then diminishing quickly from west to
east. Nothing notable noted on forecast soundings or QPF with
this system, with just regular ol' showers and a few
thunderstorms anticipated and rainfall totals of just 0.25" to
0.50". After the current forecast period, both the GFS and ecmwf
continue to depict 850mb temperatures falling below 0c across the
area, which if it pans out would bring us the coolest
temperatures so far this month by the middle of next week.

Aviation
12z TAF discussion.

Patchy fog and low clouds once again are occuring along bodies of
water and rivers. Expect this to lift after sunrise. In the mean
csv will flirt with lifr. The fog isn t as bad at csv where it is
MVFR.

Once the fog burns off no issues are expected. Southerly winds of
5-10 kts are expected until sunset when winds will decouple and be
calm to light.

Patchy fog is expected once again overnight tonight. At this time
will go with MVFR but it could once again go down to ifr.

Ohx watches warnings advisories
None.

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.
