Showers contracting offshore with the fdevelopment of the land breeze.

Showers possibly redeveloping with solar heating fromafternoon and showers increase further overnight as an upper level trough approaches the region, the slight chance of a thunderstorm as well with the upper level cold pool.

Showers ease by Saturday morning as the upper level trough moves east, still possible showers throughout the weekend with the moist onshore flow, the passage of a trough on Sunday.

Areas of fog are possible early today, Saturday and Sunday with the radiational cooling of moist low level air.

A cold front moves over the region on Monday leading to further showers, further showers in the cold air mass behind the front, likely clearing by Tuesday night as the ridge of high pressure builds slightly to the south.
