Aviation
06z TAF discussion:
widespread rain showers & low flight categories, with a mix of
ifr- lifr ceilings & MVFR visibilities, are expected through today.

Some areas have already started to see some lowering of ceilings,
with widespread rain showers ongoing for areas across central &
eastern TAF sites. Some areas in the southeast are only seeing
some light rain, but more moderate rain showers & lifr ceilings &
lower visibilities are possible over the next several hours. Some
storms & vcts are possible into the afternoon, mainly across mei,
pib & hbg. Expect ceiling improvements in the delta TAF sites of
glh & gwo toVFR conditions by mid-late afternoon (i.E.

19-21z).Elsewhere, MVFR flight categories & light rain showers & a
few storms will linger well into the afternoon, while into the
early evening after 27 03-04z at mei, pib & hbg. Winds will mainly
be southerly around 5-10mph, with some higher gusts near 15mph
near gtr, mei, pib & hbg. Winds will become light overnight & more
low ceilings & flight categories are possible again tonight. Dc

Discussion
Showers continue this evening for portions of the area. Activity
is expected to continue through the overnight out ahead of an
approaching shortwave trough. Lows will mainly be in the lower to
middle 70s. As for the forecast, made some minor adjustments to
the pops for this evening into the overnight based on latest radar
and model guidance. 27
prior discussion below:
this afternoon through tomorrow:
the current short-term forecast continues to unfold generally as
anticipated this afternoon. The one exception is that there has been
less than anticipated coverage of showers and thunderstorms across
the western half of our forecast area (northeast la, southeast
ar, and western ms). Looking at satellite imagery, there may be
some influence of drier air beginning to wrap around the mid-level
circulation associated with a shortwave approaching from our
northwest. Otherwise, increased moisture being advected northward
from the gulf of mexico has helped shower and thunderstorm
activity across the eastern half of mississippi be efficient at
rainfall production this afternoon. Some 2 to 4 inch rainfall
amounts have been reported so far from choctaw county this
afternoon, and looking at dual-pol data there have been a few
storms with estimated 4 to 6 inch per hour rainfall rates at
times.

Synoptic scale lift ahead of the approaching shortwave trough axis
will help showers and possibly a few thunderstorms to continue
through the overnight hours and into tomorrow morning. Areas along
and east of interstate 55 have the best chance for seeing rainfall
through mid-morning, with chances decreasing throughout the day
tomorrow as the trough axis pushes east of the forecast area. Given
the last few days of heavy rain scattered around the same areas
seeing rain today (and threat for heavy rain through tomorrow
morning), we will continue to highlight a limited threat for flash
flooding in our hwo for the pine belt area northward through the
golden triangle area through tomorrow. Drier air should begin to
edge into the delta by tomorrow afternoon, and clearing skies will
allow for daytime heating to warm those areas up to around 90
degrees. Nf
Monday night through Wednesday:
rain chances will decrease Monday night in the wake of the
departing surface low upper disturbance. However, this break will
be short lived as a cold front approaches the area on Tuesday.

Guidance is hinting at some possibility of a remnant MCS moving
into the area early in the day Tuesday, though there is some
disagreement on exactly what if any portions of the forecast area
this would impact. Regardless of whether there is activity in the
morning, a surge of deep moisture ahead of the front will aid in
plentiful convective coverage in the afternoon. Before and outside
of any rain, the combination of warmth and humidity may lead to
heat indices in the 100-105 range, but the potential for early
convection to disrupt heating casts too much doubt to warrant
mentioning heat stress in the hwo graphics.

The front will make slow progress across the region, with
scattered storms remaining possible overnight Tuesday night into
Wednesday. However, during the day Wednesday we should begin to
see decreasing rain coverage from the north as a drier airmass
finally advects into the region.

Thursday through next Sunday: for the end of the week, it will
feel much more pleasant thanks to a noticeably drier airmass
behind the cold front. Morning lows in the 60s will be common
through the weekend. Even with daytime highs remaining seasonable,
this will be a much nicer version of temperatures in the 90s. As
the airmass gradually modifies, moisture will slowly tick back
upward over next weekend, with isolated to scattered storms
becoming possible again by Sunday. Dl

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.
