Synopsis
Upper level low digs into the tennessee valley and brings chances of
showers and storms, tapering off on Friday. Additional disturbances
provide precipitation chances over the weekend.

Near term through Thursday
As of 905 pm Wednesday...

not much change except for trying to time pops in the 0-6 hr
range.

As of 215 pm Wednesday...

upper low continues to dig into the mid mississippi valley with
energy rotating into the CWA in the cyclonic flow. The weak
instability has been overcome enough to get embedded convection
within a stratiform rain shield, making the severe threat
rather tricky given the directional shear profiles. Expecting
more convection to fire in the dry slot in the wake of this
shield where clearing has taken place. Wind and hail threat
exists as well.

Take the pops down considerably tonight in this drier air after
frontal passage from south to north with the absence of the
heating. As the low continues to rotate into the northeast,
additional embedded waves will be the source of forcing in the
cold pool aloft heading into Thursday. There will also be a low
level jet streak across the southern CWA which will help with
some of the organization of the convection, but just in the
general thunderstorm area from the SPC guidance.

Short term Thursday night through Saturday night
As of 350 pm Wednesday...

upper level low will move off to the northeast Thursday night and
Friday, with showers pulling out of the area. Models are fairly
consistent with a disturbance then moving through Friday night into
Saturday, providing additional showers, with thunderstorms possible
by Saturday afternoon.

Long term Sunday through Wednesday
As of 350 pm Wednesday...

models show a disturbance moving across the area Saturday night or
Sunday. Depending on the timing of this disturbance, could see some
decent CAPE for Sunday afternoon. Will need to keep an eye out for
the possibility of hail.

Models then diverge a bit with the timing of a cold front for early
next week. This leads to a low confidence forecast for the timing of
precipitation Monday and Tuesday, in addition to temperatures during
this time frame.

By Wednesday, cooler air from an upper level trough should be over
the area with a few showers not out of the question.

Aviation 03z Thursday through Monday
As of 1050 pm Wednesday...

showers throughout the area. Definitely an MVFR type of night
however ifr is not out of the question. In fact, becoming more
concerned that satellite imagery shows clearing towards khts
which could lend to forming some fog, but very difficult to tell
in this upper low controlled air mass. Basically expect crummy
flying conditions next 24 hours.

Forecast confidence and alternate scenarios through 00z
Friday...

forecast confidence: low
alternate scenarios: timing of shra could vary. Amendments
likely. Post thunderstorm environments tonight may vary from
forecast.

Experimental table of flight category objectively shows consistency
of WFO forecast to available model information:
h = high: TAF consistent with all models or all but one model.

M = medium: TAF has varying level of consistency with models.

L = low: TAF inconsistent with all models or all but one model.

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.
