SYNOPSIS
THE GRADIENT RELATED TO HIGH PRESSURE OVER THE
EASTERN U.S. THAT STRETCHES A RIDGE SW TO THE SE U.S. IS
SUSTAINING FRESH TO STRONG NE TO E WINDS AND MODERATE TO ROUGH
SEAS OVER THE NE GULF. THESE CONDITIONS WILL SPREAD WESTWARD OVER
THE REMAINDER OF THE NORTHERN GULF WATERS THROUGH LATE THU NIGHT

RATHER BROAD MID TO UPPER-LEVEL TROUGH WILL MOVE TOWARDS FLORIDA
