Marine Weather and Tide Forecast for Atlantic Beach, NC

KEY MESSAGES
1) Dry with record heat possible rest of this week.

2) A strong and mostly moisture starved cold front will move through the area Friday evening. Drastically cooler and drier weather behind the front, along with gusty N-NW winds which could bring a period of dangerous marine conditions and minor coastal impacts.

DISCUSSION
KEY MESSAGE 1...High pressure builds in from the west through most of this week with sunny skies. Building hts as upper ridge strengthens sends temps soaring through the 80s and nearing 90 for some interior locales (record high climate section below).
A back door front moves into nrn parts of ENC later Thur, but quickly retreats north by early Friday with another surge of swrly flow ahea of much stronger front. No moisture with the backdoor front, and only temporary reductions in temps for nrn 1/3 of ENC.

KEY MESSAGE 2...The aforementioned much stronger cold front will sweep through ENC Friday night, and good model agreement with this system. Front still appears moisture stared due to it's very fast movement and no connection to the Gulf. Strong forcing is associated with it however, so a skinny line of showers may drop only a few hundredths at best for most areas in the span of less than an hour Fri evening. Coolest and driest airmass for the fall season thus far builds in behind this front with temps taking a nosedive with highs in the 60s and lows in the 40s (inland) and 50s (beaches).

With this strong front, winds rapdidly inc from the NW Fri evening with a short period of gales for most of the waters and sounds, and would bring a sharp increase in high seas especially on Sat as the winds turn northerly and persist to near gales on the coastal waters. Minor coastal impacts could occur too, though short duration of strongest winds may act to limit more appreciable impacts. It's still too soon for specifics on coastal flooding potential.
