Big changes for the Saturday forecast as instead of staying separate, the upper-level low (ULL) partially captures the surface low and pulls it in and rides it inland up the coast. Rain will overspread the area from SE to NW with the wind quickening up in the afternoon.

For Sunday the surface low departs and the ULL edges a little east. Most models have a good part of the day rain free with activity not picking up until late in the afternoon.  I think once it does, much more of  the area will be involved

Showers and thunderstorms will be around Monday and Tuesday . Unsettled weather continues Wednesday.  Wednesday night into Thursday, a cold front brings increased showers and thunderstorms.

It finally looks like things quiet down Friday and into next weekend.
