.DISCUSSION...

.Short Term...Today through Wednesday.
Main forecast issues in the near term will be POPs for today.
Thunderstorm activity had dissipated this evening over the region
but activity has continued across SE Louisiana and offshore
waters. Broad upper level ridge has shifted further west. Sagging
of upper level trough over the Gulf Coast states today is
forecasted to increase upper diffluence. Will therefore have
higher than normal POPs for today with best chances over central
Louisiana and lower Acadiana region. For Wednesday...have have
highest rain chances over extreme southeast Texas and southern
Louisiana as best upper diffluence shifts over to these areas.

.Long Term...Wednesday night through Monday
Upper trough will shift a little further east on Thursday and
then lift northeast late in the week. This will allow upper ridge
to slowly build over the Southern Plains. Will therefore be
lowering POPs to the 20-30 percent range during the daytime hours
Thursday through Saturday. For next week...continued with low POPs
as per model blends. At this time...no significant heat issues are
anticipated through Saturday. For next week...preliminary
forecasts of maximum heat indices will trending to 105 to 108.




&&

.MARINE...
Upper high pressure ridge will continue over the northern Gulf
through Thursday. The ridge will shift north late this week
allowing for weak onshore flow. Outside of thunderstorm
activity...no marine hazards are expected.
