Synopsis

A strong area of high pressure will remain in place to our north through the remainder of the week leading to a prolonged period of onshore flow. A strong coastal low will then develop in the Atlantic Thursday and intensify as it lifts northward into this weekend. Small Craft Advisories will likely be needed for much of the Friday through Saturday time period, and a few low-end gale gusts can't be ruled out.
