High pressure over the gulf with significant solar radiation is causing a widespread marine layer, which is attempting to stay over land. As the sunlight diminishes tonight, the thermal gradient will reverse to begin to move the marine layer over land in force yet again. Windier conditions and some drying at the surface will mostly prevent large scale advection fog as the layer moves in. Otherwise, Wednesday looks like more of the same weather pattern, complete with a visit from the sun and large amounts of local sea breezes. .LONG TERM.../ Thursday to Sunday night / Weak high pressure over the eastern gulf and panhandle are holding in place through Friday. A short wave will move from the southwestern gulf across the southern gulf and southeast towards the Pacific Northwest by Friday morning. A larger low moves into the Bering Sea Friday and Saturday while drifting east. The associated frontal will move into the panhandle area Saturday, with main panhandle more later half of Saturday. Am not expecting any winds over 20 kt until the weekend time frame and those will be starting over the outer gulf waters. && .AVIATION...Light winds, quiet weather over next 24 hours. Not many significant concerns for aviation operations except for the Marine layer. MVFR along the coast, with VFR over most of the inner Panhandle. && .AJK WATCHES/WARNINGS/ADVISORIES...
