Short term (today through Wednesday)
An active pattern is expected across the southern tier of u.S.

States over the next few days with a series of shortwave troughs
moving east to east-southeast through the southern plains into the
southeast states. The most potent shortwave trough will move out
the southern plains into the lower mississippi valley and central
gulf coast region today and push east of the forecast area on
Tuesday. Upper level divergence is well noted on water vapor
imagery ahead of the shortwave, and the models continue to
indicate much of the forecast area will remain in the divergent
area through Tuesday. High precipitable water values near to
excess of 2 inches should be widespread over the forecast area
during the afternoon today. Organized clusters and lines of
thunderstorms from yesterday left surface boundaries that will
help focus early convective activity this morning, mainly in
coastal areas, then the approaching shortwave trough will increase
coverage of showers and thunderstorms from the west and inland
with the seabreeze in the afternoon. Typical moderate to high
instability from daytime heating and the high moisture content
will lead to numerous thunderstorms and many will produce frequent
lightning and heavy rainfall. Movement should keep most of the
heavier short term rainfall rates in the 1 to 2 inch per hour
range, however localized areas where more stationary or repetitive
bands set up could see some 3 to 4 inch amounts through the day.

Severe thunderstorms are not expected due to the very moist column
that is expected from the lower to mid levels of the atmosphere,
however strong winds may occur with more organized clusters and
lines, especially where storms are moving faster or where there
are colliding boundaries.

The stronger shortwave trough should move through early Tuesday,
however additional minor shortwaves may move through in west-
northwest flow. Another convective complex may move through the
region, and showers and thunderstorms should be numerous over most
land areas with scattered showers and thunderstorms expected
offshore. Gusty winds and heavy downpours will again be possible
with scattered to numerous thunderstorms. Deep layer moisture
content will be decreasing over the far inland areas Tuesday and
over more of the forecast area on Wednesday as slightly drier air
works into the area from the north and west, however additional
low amplitude shortwave troughs moving through in the relative
fast mid level flow will support continued elevated chances of
showers and thunderstorms on Wednesday (40 to 50%).

Long term (Thursday through Sunday)
Another low amplitude shortwave trough over the gulf coast states
associated with a stronger shortwave trough moving through the
ohio valley on Thursday will continue to support the typical
diurnal development of scattered showers and thunderstorms. A
subtropical ridge should then expand out of the tropical atlantic
into the gulf of mexico and central to eastern gulf coast Friday
and Saturday, so a drier and warmer pattern is likely to return
with only a 20 to 30% during peak heating hours. The ridge does
move east on Sunday the westerlies aloft become active again
across the southwest and south central u.S. Into the lower
mississippi valley, so rain chances may rise again over at least
western areas near the atchafalaya river. 22 td

Aviation widespread convection expected through the afternoon
and evening hours with tempo groups at all terminals.VFR
conditions will prevail outside of any thunderstorm activity
through the period for all terminals. Light south winds expected
expect higher in and around any thunderstorms that occur this
afternoon and evening.

Marine
A series of upper level waves will move across the region through
mid week keeping scattered thunderstorms in the forecast. Southerly
flow will continue through the forecast period as surface high
pressure sits of the atlantic southeastern coast. Showers and
thunderstorms expected to increase in coverage on Monday and Tuesday
while synoptic winds will decrease. Southerly winds expected to
increase late week as gradient tightens and surface high builds
westward into the northeastern gulf. Chances of showers and storms
will decrease by the end of the week as ridging builds in over the
area.

Decision support
Dss code: blue.

Deployed: none.

Activation: none.

Activities: flood warnings continue along the mississippi and
atchafalaya rivers.

Decision support services (dss) code legend green = no weather
impacts that require action.

Blue = long-fused watch, warning, or advisory in effect or high
visibility event; marginal risk severe or excessive rain.

Yellow = heightened impacts with short-fused watch, warning or
advisory issuances; radar support for slight risk severe or
excessive rain.

Orange = high impacts; enhanced risk severe; nearby tropical
events; hazmat or other large episodes.

Red = full engagement for moderate to high risk of severe and or
excessive rain; direct tropical threats; events of national
significance.

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.
