Update
For 12z tafs.

Near term (today)
issued at 347 am cdt Mon oct 15 2018
the forecast area is in between a building ridge centered across fl,
and an amplified, positively tilted trough moving into the great
lakes. A lingering boundary to our northwest will continue to bring
showers this morning, with higher pops across NW al and southern
middle tn (much like yesterday). As the sfc low scoots east of the
great lakes, it will pull the associated cold front southeast into
the region later this afternoon. Ahead of the front, there will be
some isentropic lift and winds will become southerly, increasing
showers to become scattered areawide with the increase of moisture
and temps. Cannot rule out a rumble of thunder so included isolated
thunder chances in for this afternoon. Daytime highs reaching the
upper 70s (maybe 80 degrees), will be the warmest in the forecast
package. The front will move through fairly quick and behind the
front, winds will become northwesterly and increase to ~10mph with
gusts ~15mph.

Short term (tonight through Wednesday night)
issued at 347 am cdt Mon oct 15 2018
northwesterly winds will filter in cooler air behind the front,
getting overnight lows down into the lower 50s across NW al and
southern middle tn and into the upper 50s across NE al. Precip
chances will linger into tonight, but become more isolated later
tonight.

On Tuesday, the front will be south of the forecast area but we will
still be in between the ridge to our southeast and a trough to our
north. The southwesterly flow aloft will stream disturbances into
the tn valley and combined with isentropic lift, precip chances will
increase through the day. Kept a slight chance of rain going in early
Wednesday to accommodate the discrepancy between the GFS that clears
out the precip faster than the ecmwf. Conditions will be dry, and
cooler, by Wednesday afternoon with decreasing cloud cover. Daytime
highs will be in the mid 60s and overnight lows will dip into the
upper 40s as skies become mostly clear.

Long term (Thursday through Sunday)
issued at 347 am cdt Mon oct 15 2018
upper level ridging will in place over the SE north american domain
on Thursday. This ridge will weaken somewhat during the course of the
remainder of the week, as troughing in the northern stream begins to
sharpen during the weekend. The amplification of the trough in part
will be caused by an upper disturbance speed MAX moving across
british columbia Wed thu, merging with energy ejected from an upper
low over the intermountain west. There was reasonable inter-model
agreement from the gfs, ecmwf, canadian into next Sunday regarding
their respective forecasts of the 500mb level. At the surface, high
pressure layered over the ohio valley will move eastward, resulting
in NE winds on Thursday becoming east, then SE on Friday. This will
gradually bring additional lower level moisture across the southeast
conus and rain chances - just in time for the weekend.

The deterministic models were good agreement with rain chances late
Friday and on Saturday. Following them, have lower end rain chances
starting Friday afternoon for our tennessee counties and along the
far northern alabama border region. Better chances for showers are
expected Friday night and Saturday morning, as a cold front pushes in
a nw-se manner across the forecast area. Post frontal showers
occurring north of the boundary will gradually end from north to
south as colder and drier air slowly filters in. Although there was
shear preceding accompanying the front, not enough instability was
present, therefore kept thunder out of the forecast.

Daily high temperatures in the extended will trend below seasonable
norms. Highs on Thu Fri will range in the upper 60s to around 70,
below average highs of around 74. Highs in the mid 60s Saturday will
cool to around 60 on Sunday. Night time lows above normal Thursday
and Friday nights (around 50) will cool into the mid 40s for Saturday
night. Lows nearing 40 look possible Sunday night, with a few upper
30s in those normally colder spots.

Aviation (for the 12z tafs through 12z Tuesday morning)
issued at 612 am cdt Mon oct 15 2018
vfr conditions will start off the TAF period. As a cold front pushes
into the area, ~18 19z CIGS will fall into lower MVFR category
(1500-2000ft) and vcsh begins. Northerly winds will increase behind
the front ~10kts, showers taper off, and CIGS remain in MVFR,
however will not rule out the chance they fall into ifr temporarily.

Most models agree that CIGS will remain low-end MVFR til the end of
the TAF period, but they do not agree on timing for rainfall to
return so kept a mention of rain returning out for this taf
issuance.

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.
