Short Term
Similar convective outcome as yesterday with limited convection on suppressed gulf breeze convergence zone over Terrebonne Parish, moving SE towards to coast. Once again, this will become part of the nocturnal land breeze process for the near coastal waters overnight. Still a weak surface pressure pattern with a third day of marginal stagnation for a little more haziness Friday over much of the area in the morning, then partly cloudy and warm for persistent temperatures Friday and Saturday. Rain chances should remain slightly less than normal through Sunday before trending upward.

Long Term
Surface flow becomes more onshore oriented later Sunday through much of next week to bring rain chances higher each day, mainly on sea breeze regime but somewhat enhanced by a frontolytic boundary that will be lingering and masking the sea breeze. Temperatures should be tamped by increased cloud and rain coverage during the extended period.

Marine
Continuation of light winds and low seas for the much of the period. There will be a brief period of a ground swell train with a period 8 seconds dampening out Saturday, which may provide a duration of 2-3 foot swell, but currently will indicate a significant wave 1-2 feet Saturday as the secondary period from the Yucatan Channel will aid in dampening the Florida Straits longer period swell.
