For the next two days, New England will be sandwiched between two systems: a coastal storm to the east and a cold front to the west. The coastal storm will pass New England well offshore, sending only some clouds into eastern New England for the most part. The exception will be far eastern Maine, where the edge of the shield of rain may swipe Washington County. The cold front will push through New England Saturday late afternoon through Sunday morning, bringing a round of showers.
Friday will be the last completely dry day for the entirety of New England as these systems remain well to the east and west of the region. As the coastal storm passes through the outer Gulf of Maine, it will create rough seas with large waves and rip currents impacting the southern New England coast. A high surf advisory is in effect through Saturday evening for the Massachusetts coast. This will be the extent of impacts from this storm.
This storm is still being monitored by the National Hurricane Center as it may briefly become a subtropical storm. The NHC currently gives the storm a 20% chance of developing into a tropical or subtropical system. This doesn’t change anything or heighten concerns, it’s just an interesting development.
