Short term (today and tonight) Ridging between weather systems
will mark the short term. Warm temperatures of 10-12 degrees above
normal are expected, with fair weather. Light winds today will
become southerly overnight. Upslope precipitation on the nc side of
the mountains late tonight may flirt with tn mountain communities on
the state line, but will maintain the non-mention of precip.
Long term (Thursday through Tuesday) Main concern is a strong
upper trough lifting east fro the central/southern plains into the
tennessee valley Thursday and Thursday night. Strong jet streaks
will move across the upper low across the tennessee valley with
broad upper divergence across the region. The circulation around
these jets will produce strong upper forcing across the tennessee/
mississippi valleys. In response to the upper forcing, a strong
low-level jet will develop as well with 850mb winds of 50-60kts
pulling abundant moisture/instability into the tennessee valley,
especially the western and middle tennessee.
Very favorable environment for tornadoes development with good
shear and thermodynamics over the western half of tennessee
tennessee and mississippi valley with long-lived tornadoes
anticipated. Main question for the plateau and southeast tennessee
is if these tornadic supercells can make into this far east into
lesser environment. Cips analogs suggests there is a threat into
the plateau and southeast tennessee with SPC pulling a slight risk
into these areas. For the central valley, there is a threat of
damaging winds as these storms weaken with a marginal risk.
For the northern half of tennessee valley into southwest virginia,
the strong southerly low-level jet will produce downsloping
conditions limiting convection. The strong low-level jet combined
with favorable thermodyanmic conditions will set the stage for
mountain wave high winds for the far east tennessee mountains and
foothills for late Thursday through early Friday morning.
This system moves east of the area Friday morning, but wrap-around
showers will continue for the northern/eastern areas Friday
afternoon and night.
Upper ridging returns for Saturday and Sunday with the next strong
upper trough expected for Monday and Tuesday. Strong dyanmics with
this system as well with showers and storms likely.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
