Discussion
A weak high pressure system is in place over our area and is
expected to persist through Monday. In general, this will lead to
warmer and drier conditions overall. However, southerly winds are
enhancing the presence of moisture and lifting in the atmosphere.

Also, upper level divergence will enhance the uplift in the
atmosphere. These conditions will lead to the development of
afternoon thunderstorms through Monday.

Beginning Tuesday through Thursday next week, a weak low pressure
frontal system is expected to move through our area. This system
will likely enhance rainfall chances next week, especially Tuesday
and Wednesday. The persistent southerly to southeasterly winds
will enhance the lifting in the atmosphere leading up to this
event. In addition, there will likely be some directional shear in
the environment, enhanced by the southeasterly winds. The amount
of buoyancy in the environment should also be average to high due
to the enhancement of the CAPE by the abundant moisture
availability. The dynamic forcing created by the frontal system
will help to develop showers and storms along and ahead of the
frontal forcing region. Some of these storms could be severe given
the diurnal considerations, compressional heating for more
efficient initiation. Main concerns will be stronger downburst
winds and possible squall conditions. General model consensus
shows that the front is expected to slow down and stall for a day
or two near the louisiana and mississippi gulf coastlines. If this
occurs, the precipitation amounts could be higher and flash
flooding could be possible. More details about this possibility
would be more apparent closer to the event.

After Thursday of next week, the normal weather pattern is
expected to dominate and conditions will return to near normal as
the frontal influences diminish over time. Msw

Aviation
Lingering isolated convection to dissipate with sunset over the
region withVFR cavok conditions expected overnight. Generally
repeat of convective onset predominantly on lake breeze boundaries
mainly after 17z Saturday. Rr 24

Marine
Continuation of steady state onshore flow to persist for much of the
forecast period. A weak frontal boundary is expected to stall near
the coast but should have little impact aside from potentially
higher thunderstorm coverage near shore by middle of next week.

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.
