Update
For 06z tafs.

Near term (rest of tonight)
issued at 910 pm cdt Sat jul 21 2018
quiet evening across the tennessee valley as dry air (very evident on
the latest goes-16 water vapor imagery) continues to filter into the
area in wake of a cold front that has currently shifted into
georgia. In response, dewpoints have actually dropped into the upper
60s in many spots -- with a few mid 60s readings noted across
southern middle tennessee. This drier air will mean an end to the
thunder threat for the remainder of the night -- as the best moisture
(and any real forcing) is displaced to the south and east of the
region. The broad upper-low (centered over the mid-atlantic coast is
sending a few weak shortwaves into the spine of the central southern
appalachians. However, the mean flow (along with the better
moisture) will keep this activity displaced over tn nc ky. Thus,
other than a very rogue shower, it will be a dry night over the
region.

In addition, this drier air will also make for a mostly clear night
and some cooler overnight low temperatures (thanks to a slightly
drier boundary layer). A set-up for decent radiational cooling is in
place tonight, so long as winds remain weak or decouple after
midnight. Thus, overnight lows in the 65 to 70 degree range will be
fairly common, though a few urban areas may stay a degree or two
higher. The forecast remains on track, with only minor tweaks needed.

Short term (Sunday through Sunday night)
issued at 238 pm cdt Sat jul 21 2018
during the day on Sunday, expect the storm system currently over
indiana and the great lakes region to push southwest towards the
area. This should increase pops again, especially in the afternoon
and early evening hours east of i-65 and in southern middle
tennessee. Based on overall lift associated with this system, think
40 to 70 percent chances of showers is appropriate. Thunderstorms
should be more isolated in nature with lower instability and not as
much wind energy available. Still should see some thunderstorms and
some decent rainfall, with pwats remaining around 1.6 inches. This
activity should become more scattered in the evening hours, before
becoming isolated after midnight.

Long term (Monday through Saturday)
issued at 238 pm cdt Sat jul 21 2018
an anomalous upper low will be cut off and centered over the
southeast on Monday with broad upper ridging over much of the western
us and midwest. This pattern will persist through at least Friday.

Atlantic moisture will be wrapping around the low so the east-
northeast flow over the area will help usher in continued moisture.

The continued shortwaves wrapping around the low combined with
afternoon heating will provide the area with scattered to numerous
showers and thunderstorms every afternoon through Friday with the
highest coverage in the eastern half of the area. It's still hard to
say where the gradient will end up of the highest lowest rainfall
amounts as any minor shift in the low will affect it. For now, will
keep the superblend likely pops in the east and chance in the west.

Have lingered some pops overnight each night and that will be refined
as we get closer to the event.

The cut off low finally dissipates as another low develops north of
mi with a broad trough dipping south towards alabama Friday night. A
front will develop back to the west and will move south through the
area by Saturday afternoon. Given how far north the lift will be,
the front will generally weaken dissipate as it approaches with just
a slight wind shift to the west and scattered thunderstorms
accompanying it.

High temperatures on Monday may actually feel "cool" dare I say with
highs in the lower to middle 80s. As the upper low dissipates through
the week, heights rise again and a slow warming trend will begin. By
Friday and Saturday, highs will be back to around 89 to 91 degrees.

Lows through the week will be in the middle 60s to lower 70s.

Aviation (for the 06z tafs through 06z Sunday night)
issued at 1213 pm cdt Sat jul 21 2018
vfr conditions will be the predominant flight category at each
terminal through the period. A mostly clear sky will prevail for the
remainder of the night, before clouds increase later this morning
and afternoon. Sct bkn decks around 4 kft are expected, with vcsh
possible at each site between 20-00z. This activity will wane with
the setting sun, but mid-level clouds will remain through the period.

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.
