SYNOPSIS

High pressure will build in from the north through the weekend with a weak inverted trough moving westward across the western Gulf of Mexico. The gradient between the two will allow for an increase in easterly winds, becoming moderate, along with increasing seas, that may lead to small craft exercise caution headlines for the coastal waters. The inverted trough will also bring a chance for showers or storms for the next couple of days.
