323am CDT Sunday September 22 2019
Ridging aloft will dominate the southeast conus and Gulf Coast states through the forecast period, although it will be suppressed to the south to some degree during the last part of the upcoming workweek before strengthening again over the region next weekend. This, along with relatively dry air, will serve to inhibit much in the way of convective development during the period. The best chance for convection will be during the last half of the workweek when the ridge weakens, but even then only isolated showers and storms can be expected. Otherwise, mostly sunny skies and above normal temperatures will be in the offing.
Tides are running around 1.5 above normal this morning along portions of the coast, but should begin to subside today after the astronomical high tide cycle this morning as the easterly winds across the coastal waters start to diminish. 11
The pressure gradient will begin weakening across the coastal waters today and especially tonight into Monday resulting in diminishing winds. The Small Craft Advisory will replaced with Exercise Caution headlines for today with this forecast package. After today, winds will become generally light and at times somewhat variable across the coastal waters into the middle of the week. 11
