Discussion
After an active period of rain and flash flooding across portions
of the mid state, we are finally reaching the conclusion of
today's heavy rainfall. The good news is we will be largely dry
for about the next 18 to 20 hours. Unfortunately, the advertised
rainfall for Thursday afternoon through early Sunday is still on
schedule. Moisture will meander back into our southern counties
mid day to early afternoon tomorrow before overspreading all of
middle tennessee by early Friday morning. At the surface, a warm
front will be making slow northward progress through the day on Friday
and looks to effectively slow or stall out over north alabama and
southern tennessee Friday evening into Saturday morning.

Depending on where the front slows and or stalls Friday into
Saturday, flash flooding concerns will certainly ramp up as
rainfall tracks over many locations that are already very
saturated. Wpc QPF has ticked upward based on latest model
guidance, and an additional 2 to 4 inches of rainfall Thursday
through Sunday morning is expected. The axis of heaviest
accumulations will, again, largely depend on the west-to-east
orientation and speed of Friday's warm front.

With waves of rain continuing Friday into Saturday, our attention
turns to the west to a digging, longwave trough over the
southwestern us. A low pressure system is anticipated to develop
and work northeast across the midwest Saturday morning and early
afternoon. In response at the surface, a cold front will develop
and work eastward into western tennessee by mid day. Showers and
thunderstorms will be developing ahead of this front, and with
just enough instability and decent wind shear, we will be
monitoring the potential for a few severe storms Saturday
afternoon evening. Once the front pushes through the mid state
late Saturday into early Sunday, we will be through and done with
the rain. Next week looks to start dry, before low end rain
chances return mid week.

Temperatures will be near to slightly above normal levels, with
the exception of Saturday... When highs will surge into the low
70s. All in all, be prepared for additional rain, flooding
concerns, a few strong to severe storms Saturday, and then a
welcomed drying out to start the new week.

Aviation
00z TAF discussion.

Showers have mainly moved off to the east, so CIGS should slowly
improve overnight. Ifr MVFR CIGS can be expected at
kckv kbna kmqy, with some ifr MVFR fog possible at all terminals.

Cigs should becomeVFR for kckv kbna kmqy by late morning
Thursday, with MVFR CIGS continuing for kcsv possibly through the
first half of the day, and winds look to be northeasterly around
5 to 10 knots Thursday. Winds overnight will go from
southerly southwesterly in the evening to northwesterly northerly
during the overnight hours at around 5 to 10 knots.

Ohx watches warnings advisories
Flash flood watch until 6 pm cst this evening for clay-
cumberland-fentress-overton-pickett-putnam.

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.
