A tropical wave is near the Yucatan Peninsula & will move steadily northwest emerging over the Bay of Campeche later Wed. into Thu.  From there the disturbance will turn north then northeast along a cold front diving southeast into the Western Gulf.  At this point, it looks like weak low pressure will evolve then move quickly northeast by Fri. into Sat. along the front to the Central Gulf Coast.  It does not appear that this low will have enough time to significantly develop but something to keep an eye on.
