A warm surge Monday, then cooler with two separate impactful systems expected this week…

A mix of clouds and sun to begin Monday, and turning unseasonably warm on the opposite side of a warm front. Clouds will increase later in the day, then showers arrive during the evening and evolve into a steady rainfall overnight…which could be heavy at times.

Low pressure responsible for the rain Monday night will sit and spin off the coast on Tuesday with periods of rain likely…which again could be heavy at times, and tapering to showers later in the day and overnight. Morning clouds on Wednesday will give way to partial clearing, then partly cloudy Wednesday night and Thursday in between systems. The next system and is likely to arrive toward the end of the week with more showers and periods of rain possible, centered around Friday as the main show, with lingering showers on Saturday. Breezy conditions will also be possible with that low as it crosses over or nearby. The low pulls away on Sunday with improving conditions expected, but still an isolated shower possible until it does so.
