Detailed Forecast


Synopsis: A broad weak ridge centered over the Gulf coast and southern Panhandle region persists into the start of the week. A low pressure system moves into the East Central Gulf Monday. This low will cause southeast winds to increase along the coast as they reach the north Gulf. A tightened pressure gradient caused by troughing in Canada will also increase winds diurnally within the Inner Channels for the next few days.
