Updated for 06z aviation discussion

Aviation
06z TAF discussion:
widespread showers continue to move southeast across the arklamiss
delta region at late evening and will continue to move through the
rest of the area overnight into Thursday morning as a cold front
pushes across. As the rain moves in, MVFR conditions will be seen
as ceilings and visibilities lower. The majority of the rain and
the frontal boundary will clear most TAF sites by mid morning
Thursday, however, lingering showers will be seen around gwo and
gtr as the core of the system moves across there. Conditions will
improve from the west after 27 00z. 26

Discussion
Made a few minor tweaks to the short-term forecast to account for
latest trends in guidance, but overall forecast remains on track.

Did remove the mention of thunderstorms for most of the area
tonight and tomorrow, as elevated instability is minimal and any
thunder is expected to be extremely isolated. Drier and cooler
weather expected tomorrow in the wake of the upper trough and
associated surface cold front. Nf
prior discussion below:
mostly clear skies have provided a rather pleasant afternoon with
temperatures generally in the middle to upper 70s, right around
average for late april. However, thick cirrus clouds are already
increasing from the west ahead of a well-defined upper wave over
oklahoma. This system is producing a widespread band of rain across
the red river valley into much of arkansas, and this activity will
overspread most of the forecast area later this evening and
overnight as the upper wave tracks into mississippi through sunrise.

A limited period of return southerly flow ahead of this system will
limit instability and moisture return so that any thunderstorms
will be isolated and weak, and rainfall amounts should generally
be around a half inch or less. A few locations in northern
mississippi may see rainfall amounts approach an inch, but these
amounts should generally remain north of the forecast area. As a
result, most area rivers that are in or near flood stage should
see little impact from tonight's rainfall.

Most precipitation should exit the area into alabama by early
Thursday morning, although cold air advection and weak low-level
instability behind the upper wave will likely result in some
scattered showers redeveloping tomorrow afternoon particularly
across northern portions of the forecast area. A second upper wave
will swing through the region on Friday with another round of
showers and a couple of weak thunderstorms possible through the
afternoon, but rainfall amounts should be generally light.

Persistent northwesterly flow heading into early next week will
provide dry weather through the weekend and into early next week
while temperatures remain near or slightly below normal. The next
appreciable chance for precipitation will arrive Tuesday and
Wednesday ahead of a large upper trough encompassing much of the
western and central u.S. Most indications at this time are than any
strong storms or widespread heavy rainfall should stay north and
west of the forecast area.

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.
