Friday and Saturday are looking sunny with warm temperatures, a weak cold front moves onshore from the Northwest on Saturday night into Sunday morning with cloudy conditions and some isolated showers. The surface ridge builds back on Monday with some lingering cloud, but improving by the afternoon. Tuesday into next Friday is looking nice with warm seasonable temperatures and mostly sunny skies. Keep an eye on the next  low to our North.
