Synopsis
High pressure builds into the area, resulting in drier and warmer weather. The first of a series of weather systems will approach the area late Saturday. Expect unsettled weather through much of the first half of next week.

Short Term - Today through Saturday
Morning fog and low stratus has developed in much of the lowlands. This will begin to scatter out once the sun rises with mostly clear skies by this afternoon. High pressure will remain over the area for Friday, giving us one more warm and sunny day before unsettled weather makes its return. Saturday is still expected to be nice, just not as sunny and warm as Friday. A The first of a series of weather systems will make its approach later Saturday, with rain moving in after sunset.

Long Term - Sunday Through Wednesday
Rain will continue to move through the area late Saturday night/early Sunday morning. There is a bit of a shortwave disturbance associated with this system that may be enough to produce some convection offshore, but anything that forms will be rather weak as the atmosphere becomes stable aloft. Since we are now officially in autumn it is only appropriate that the next weather system approaches the same day as one leaves. This second system is on the stronger side and models are in agreement that it will bring widespread rain and high mountain snow to the area. Unsettled weather will remain in place until at least mid week. This unsettled weather pattern will keep showers in the area including the potential for some thunderstorms. Welcome to fall.

Marine
