Short term
Surface low from cindy now over arkansas while an upper low
remains back over northwest louisiana. This is where residual
moisture is able to develop some strong to severe thunderstorms.

As the moisture and remains of cindy get picked up in the
westerlies, the moisture along the axial bands are getting
stretched and sheared along the east side of the upper trough
north of the area. The line of sh TS will get reinvigerated today
with heating but will also begin to become more oriented east west
through Saturday as it becomes more involved with a cold front
that will be moving into the area as early as Saturday evening
before slowing to a crawl. But concurrent model runs continue to
suggest this boundary eventually making it through the area by
Monday. Basically, it will take the boundary almost 48 hours to
move from mccomb miss to the coast. Some dry air and weak
northerly winds are expected to move into the area for a short
stay late Monday through Tuesday.

Winds will slowly ease through today but they have been high
enough to keep water piled along the gulf coast preventing area
lakes from draining very fast. Water levels will continue their
slow fall through the next 24 hours. Lake levels should improve
enough today to keep water from most roadways but still expect
minor flooding of the lowest areas along the coast during high
tide today. The coastal flood advisory will remain into the
afternoon hours today but will likely be lowered as water should
be low enough after today to keep roadways dry. There are some
indications that minor coastal flooding will remain through the
weekend, but this does not make sense with wind speeds around 10
to 15 mph and enough drainage that should prevent further coastal
flooding into the weekend. For this reason, the advisory will not
be extended in time. Although, tides will remain unusually high
with no meteorological forcing to favor lower levels.

Showers with a few thunderstorms will continue to contain heavy
rainfall but should not be enough to cause more than minor issues
such as flooding of some raodways, low lying and poor drainage
areas.

Long term
Wednesday will see moisture begin to once again return to the area
with sh TS developing once again. But we should be moving into a
more summer routine with daily sh TS around.

Aviation
Primarily MVFR ceilings around fl015 this morning, occasionallyVFR.

Will carry vcsh as necessary based on radar trends early this
morning. Current hrrr output indicates most of the morning hours
should remain dry, and will hold off on any mention of vcts until
after 18z. Afternoon conditions outside of convection likely to be
bkn025-035. Most convection should dissipate near or shortly after
00z. Likely to see ceilings fall below fl020 again after 06z
Saturday. 35

Marine
Winds continue to ease back to moderate levels and will be low
enough to take SCA flags down by this afternoon. Swell will remain
around 3 feet causing a combined sea state of 5 to 8 feet through
the early afternoon. Winds are expected to remain light Saturday
through Sunday before becoming northeast around 15kt as a cold
front should edge into the northern gulf coast. Areas of sh ts
will remain through the fcast as the front is not expected to move
farther offshore.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
