Our unsettled weather pattern will continue tonight and into Friday. Well above normal rain/thunder chances will aid in providing drought relief, as well as bringing temperatures down closer to normal thanks to increased cloudiness and shower/storm coverage. High uncertainty does remain regarding the wind forecast. Expect generally gentle to moderate NE-E breezes, but periodic wind surges will be possible.
