Synopsis: A front extending from Yakutat SW into the Gulf will steadily progress eastward over the northern panhandle Thursday, increasing southerly winds. This will displace the high pressure over the southern inner channels. Low pressure develops over the NE gulf behind the front Thursday night, then tracks southward Friday, causing a shift in wind directions.
