WHAT TO KNOW

  • More showers are expected for tonight, the sky remains cloudy and temperatures generally in the 60s.
  • Monday through Thursday is mainly dry, but mostly cloudy and cool.
  • A coastal storm will bring a risk of coastal flooding during high tide starting Wednesday through next weekend. Heavy rain and gusty wind is possible but the timing and track of this storm is still uncertain as of Sunday evening's forecast.

Early Work Week

The Monday morning commute will be overcast with an isolated shower, but the rest of the day will be dry with peeks of sunshine. Morning temperatures will be just shy of 60, with afternoon highs near 70. It will be cooler than average, but Monday will be the mildest day of the week.
Tuesday and Wednesday are much cooler, with mostly cloudy skies and a stray shower possible. Highs are in the low to mid-60s, with a strong breeze from the east at 15 to 20 mph.

Tracking a coastal storm

A coastal storm could develop later this week and bring a stronger east breeze to the area starting on Thursday. There could be minor to moderate coastal flooding during the high-tide time starting Thursday. It's too early as of Sunday evening's forecast to say what, if any impact the storm will have on the area, but there is the potential for it to bring heavy rain and gusty wind to the island as early as Friday or perhaps into next weekend. This storm could remain out to sea. Check back with the News 12 Storm Watch Team for updates.
