Area Forecast Discussion National Weather Service Newport/Morehead City NC 928 PM EDT Sun Sep 27 2020

SYNOPSIS. Weak high pressure will build over the area tonight into Monday. A slow moving cold front will approach the area early this week and move through Wednesday night and early Thursday. Cooler high pressure expected to build over the area late week and next weekend.

NEAR TERM /UNTIL 6 AM MONDAY MORNING/. As of 920 PM Sun . No signif changes planned. Regional rdr shows area of precip to the W and SW just ahead of short wave. The rain is falling from mid lvls with very little reaching the ground. This precip will cross ern NC overnight with poss some light rain, however not expecting much so will cont at worst low chc pops.

Prev disc . High pressure surface and aloft was located over NC this afternoon and will persist into Monday. The widespread radiational fog and low stratus clouds from this morning have lifted into a stratocumulus deck this afternoon. Expect these clouds to dissipate early this evening with loss of heating. Overnight a shortwave will lift northeast across the area which will result in skies becoming mostly cloudy. The shortwave may produce enough lift to generate isolated to scattered showers from late evening into early Monday morning and will continue 20-30% PoPs. Overnight lows will be in the mid to upper 60s. Think increasing clouds should limit fog potential.

SHORT TERM /6 AM MONDAY MORNING THROUGH 6 PM MONDAY/. As of 305 PM Sunday . Could see some light showers Mon morning, then in the afternoon a tongue of moisture is forecast to move north into the area as the mid level trough approaches and coupled with a diurnal heating should result in scattered showers developing primarily over the southwest zones. Otherwise, expect a mix of sunshine and clouds and warm.

LONG TERM /MONDAY NIGHT THROUGH SUNDAY/. As of 330 AM Sun . Unsettled with temps near or slightly above climo through mid next week, then cooler and drier late next week.

Monday night through Wednesday . The upper flow is forecast to become more amplified next week with an Eastern upper trough deepening across the MS River Valley. The leading edge of the trough will be associated with a strong surface cold front which will move slowly across the Mid- Atlantic, producing scattered to numerous showers and thunderstorms. Models continue to converge into better agreement with the synoptic pattern and timing of the sfc features. Complex pattern expected, as cut off low develops at the base of digging trough over the TN Valley and then pivoting through the southeastern states. This feature will move through the SE US Wed inducing sfc cyclogenesis along the front in the Carolinas, then becoming vert stacked as it lifts up the Mid- Atlantic and NE coast Thu. A variety of weather impacts possible with this scenario, including heavy rain with localized flooding, and a potential severe weather threat. Details on mesoscale features have yet to be worked out, with ECM soln indicating heaviest axis of rain across the Piedmont of the Carolinas, while the GFS brings heaviest precip shield through E NC with at least several inches of storm total rainfall. Nevertheless, enough model agreement amongst global models, as well as their respective ensembles, to raise pops to 60-70% for the period later Mon night through early Wed. Temps will be warm and humid this period with highs in the lower 80s with lows in the upr 60s to low 70s.

Thursday through Saturday . Drier and cooler air will filter in behind the front late week into next weekend with troughing aloft and sfc high building in. Highs in the 70s with lows in the 50s this period.

AVIATION /02Z MONDAY THROUGH FRIDAY/. Short Term /through Monday/ . As of 620 PM Sun . Expecting a mainly VFR TAF with light winds this period as high pressure remains over the area into Mon. A shortwave moving across the area overnight could touch off a few very light showers with little of no impact. Associated mid clouds should inhibit radiational fog and low cloud development though the statistical aviation guidance is strongly indicating IFR- MVFR ceilings developing after 6Z. For now will have a brief TEMPO of MVFR conditions deep inland late. Bulk of Mon looks dry as init short wave moves offshore with sct to bkn clouds in its wake.

Long Term /Mon night through Fri/ . As of 330 AM Sun . Sub-VFR chances increase later Mon night and esp Tue and Wed as widespread showers with embedded thunderstorms affect the region ahead of a slow moving cold front. VFR and mo sunny returns by Thu.

MARINE. Short Term /through Monday/ . As of 920 PM Sunday . No changes with good boating conditions this period with light winds and seas mainly 2 to 3 ft.

Prev disc . High pressure will continue over the waters through Mon producing light winds. Southerly winds 5-10 tonight will be around 10 kt Mon with 2-3 ft seas through the period. Not expecting widespread dense fog overnight as increasing clouds should inhibit its development though the northern waters would have the best chance since clouds will be slow to move in there overnight.

Long Term /Monday night through Friday/ . As of 330 AM Sun . A cold front will slowly approach the waters Tue, likely not pushing through until mid week. S/SW 10-20 kt Tue increasing to 15-25 kt Tue night into Wed night with higher gusts. Confidence is increasing that waters will see a period of SCA conditions beginning Tue as seas respond by building 6+ ft. Conditions will begin to improve on Thu as winds become wrly and diminish, with high seas following suit.
