Aviation Scattered showers and storms are moving inland from
the coast this morning. This convection can be expected to produce
lower vis and ceilings. Storms are also expected to linger through
the period for the i-10 corridor terminals. Winds will generally
be light and onshore today.

synopsis...

the latest ua analysis and WV imagery shows currently centered
over the southeast la coast, while GOES 16 experimental tpw and
00z soundings around the area show precip water values around 1.9
to 2 inches. Not surprisingly, the regional radar mosaic shows
sctd showers and tstms developing along the coast and over the
coastal waters early this morning. Meanwhile, weak high pres
continues to ridge over the southeastern us and northern gulf of
mexico resulting in very light near calm winds acrs the area.

discussion...

the upper low will continue to retrograde over the northwest gulf
coast through Sunday. Increased instability and lift associated
with the low will allow sctd showers and tstms to develop over
the area this morning, especially along and south of i-10. Convection
will increase some during the aftn as activity spreads inland.

Showers and storms are expected to remain generally sctd today,
but with precip water around 2 inches, storms will be capable of
producing locally heavy downpours and high rain rates which could
result in localized flood problems. Showers and tstms will
decrease during the evening with the loss of daytime heating, then
develop again on Sunday with sctd to numerous showers and storms
expected. Daytime temperatures today and Sunday will be a few
degrees cooler than the past few days with aftn highs expected to
range from the upper 80s to lower 90s, and will be dependent on
shower cloud coverage.

By Monday, rain chcs begin to dwindle as the upper trough weakens
and shears out and upper ridging begins to build back over the
area. Ridging aloft looks to more or less remain over the region
through the week, resulting in just a slight chc of showers or
storms each day as deeper moisture gets pushed east of the region.

However, this also means daytime temperatures will warm back into
the lower to middle 90s, with corresponding aftn heat index
values ranging from 102 to 107 through the latter part of the week.

marine...

light south to southwest winds and low seas will prevail for the
next several days as high pres remains over the gulf of mexico.

Lower pres aloft will move westward today through Sunday, helping
to enhance shower and TSTM chcs over the area, with coverage
expected to be highest this morning and again late tonight
into early Sunday morning. Shower and TSTM chcs will diminish by
Monday with limited rain chcs remaining through the week as high
pres in the mid and upper levels builds back over the area.

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.
