Synopsis
High pressure building in from the north will cool temperatures back to normal through Sunday before most of next week turns warm again. Only minor rain chances could materialize late next week.

Near Term - Through Saturday
The furthest-west reaches of surface high pressure over the Atlantic will keep SWrly low-level flow in place through early this evening, except for southerly winds on the ocean side of the sea breeze. As a cold front approaches from the northwest tonight, a diffuse pressure gradient will result in light and variable or calm winds for the vast majority of the night. While this setup would normally result in widespread fog potential, increasingly thick high-level clouds associated with the front will overspread the area, limiting radiational cooling. Still, at least some mist should manage to develop over fields and near water bodies overnight. However, mid- level clouds arriving with and behind the cold front itself late in the night should further limit radiational cooling and may even cause temps to rise a degree or two, keeping fog largely at bay. Northerly winds will take over behind the front initially before becoming northeasterly by late morning as high pressure transiting across the Great Lakes takes control. Expect overnight lows to be well-above normal with the cloud cover and warm dew points limiting temps to the low 60s.

On Saturday, expect mixed clouds and sun along with somewhat cooler temps as cooler and drier air spills in from the north. A north- south temperature gradient can be expected with mid-70s north and temps topping out around 80F south.

.SHORT TERM/SATURDAY NIGHT THROUGH SUNDAY NIGHT/... High pressure to our north through the period, with an increasing ridge axis developing. The resulting Cold Air Advection will be weak keeping the nigheights above climo and daytime highs only elevated a few degrees above normal.

Long Term - Monday Through Friday
The high to our north will only slowly progress eastward early in the period turning NE winds to E and then SE by midweek. This will push the deviations above climo even higher while the overhead mid level ridge keeps measurable rain out of the forecast. At some point non-measurable showers could materialize but this seems more likely late in the week as the mid level ridge both weakens and moves offshore.

Marine
Through Saturday... Weak southerly flow around offshore high pressure and 2-3 ft southeasterly swells through tonight will be replaced by northeasterly flow on Saturday behind a cold front. Expect wind speeds to pick up to around 15 kts Saturday afternoon and seas to begin rising as wind waves build in addition to the continued southeasterly swell.

Saturday night through Wednesday... High pressure nosing in from the north in a cool season-looking pattern early in the period. The gradient will be tight enough for some advisory-worthy 6 ft seas but given that it's later Sunday have held off on SCA (Small Craft Advisory) for now esp since there's a bit of uncertainty regarding both timing and whether or not the headline is needed for all zones. Heading into the midweek period the flow will both veer and weaken as the surface high progresses east and it's ridge axis into the Carolinas retreats. The NE to E long fetch will allow for swell energy to coexist with the wind waves, likely also modifying the timing and spatial extent of the need for the advisory.
