.SYNOPSIS...
Low pressure will gradually weaken as it shifts slowly
northeastward from the Appalachians through the Mid-Atlantic
states and coastal New England through Tuesday. Meanwhile, high
pressure currently centered over the western Gulf of Mexico will
expand eastward through Monday, allowing winds and seas to
diminish overnight. High pressure will be centered directly over 
our region by Sunday evening and will then gradually weaken early
in the week as it gradually moves offshore by midweek. Low
pressure will then develop over Deep South Texas towards midweek
and will move slowly eastward along the northern Gulf coast late
this week.
