Area Forecast Discussion National Weather Service Newport/Morehead City NC 358 PM EDT Sun Aug 9 2020

SYNOPSIS. A front will linger near the area, dissipating by Monday. High pressure building in from the Atlantic then takes control through the rest of the week.

NEAR TERM /THROUGH TONIGHT/. As of 345 PM Sun . Rather stagnant upper air pattern this afternoon with a very weak shortwave pivoting over the western Carolinas but otherwise very weak flow overhead. At the surface, a stalled front continues to meander across the CWA and is currently along or just north of the Pamlico River.

Before sunset . Typical summertime pattern continues with the most robust convection firing along the seabreeze, with weaker convection along or north of the stalled boundary. Expect coverage to gradually expand inland with ongoing boundary collisions with an isolated stronger storm or two possible in an environment of 2500 J/kg MLCAPEs. Gusty winds are the primary threat.

Tonight . Front will dissipate overnight with convection gradually waning. Given the convective trends over the past couple nights extended mentionable PoPs to around 03z. Skies gradually clear overnight with winds potentially decoupling. Patchy fog is possible especially for areas that will receive rainfall this afternoon. Lows again remain in the low to mid 70s, upper 70s to around 80 beaches.

SHORT TERM /MONDAY/. As of 355 PM Sun . Similar pattern to today with front completely dissipating allowing for weak southwesterly flow across the region. CAMs are a bit more aggressive on coverage tomorrow, which is possible as the shortwave to our west gradually approaches the region. On the other hand drier air/subsidence will continue to remain a factor aloft. Opted to keep similar PoPs to today with the seabreeze once again being the primary convective initiator. Low-level thicknesses change little with highs again climbing to around 90.

LONG TERM /MONDAY NIGHT THROUGH SUNDAY/. As of 345 AM Sunday . Seasonable weather on tap through the long term period, with only minor day to day variability owing to subtle changes in the upper level pattern and strength of low level WAA.

Broad upper ridging over the southern US begins to break down Monday as shortwave energy pushes across the Midwest, with a more pronounced weakness aloft developing mid to late week. In the lower levels, continued SW flow on the periphery of the Bermuda high will keep ample low level moisture in place through the period, with storm trends following mainly diurnal patterns, with the greatest threat for thunderstorms coming each afternoon along and ahead of the sea breeze. Waning upper level subsidence and weak surface troughing gradually strengthening inland through the week allow for greater storm coverage each day (~50% POP by Thu/Fri), and would be expected to initiate convection earlier in the day with less capping in place. While ample moisture and instability will be present, shear will be meager with 0-6 km bulk shear generally around 10 kt or less limiting the severe threat. Still, cannot rule out stronger storms producing isolated wind damage and heavy rainfall producing localized flooding. Temps will generally continue to be near normal, with convection being the primary culprit for deviations from normal.

AVIATION /20Z SUNDAY THROUGH FRIDAY/. Short Term /through 18Z Monday/ . As of 145 PM Sunday . Cu field around FL030 but coverage is limited. VFR conditions this afternoon outside of tstorms that are firing along the coast and could bring brief periods of sub- VFR cats. Regional terminals are expected to have scattered tstorms later in the day beginning around 21Z. With calming winds overnight, patchy fog is expected in the footprint of rainfall this afternoon/evening; MVFR visibilities were added to the early morning hours. Tomorrow winds will be light, predominantly out of the S/SW.

Long Term /Monday night through Thursday/ . As of 145 PM Sun . Typical summertime pattern through the period with light winds and diurnally enhanced convection each day. Pred VFR conditions expected outside of showers and thunderstorms and patchy early morning fog and/or stratus.

MARINE. Short Term /Through Monday/ . As of 400 PM Sun . Favorable boating conditions continue for the period. Front is draped over the Pamlico River with easterly winds over the Northern OBX, southerly winds elsewhere at 5-10 kt. Buoys show seas of 1-2 ft. Front dissipates tonight with southerly flow overspreading all waters at around 10 kt, with weaker winds during the morning hours. Seas reach no higher than 2 feet.

Long Term /Monday night through Thursday/ . As of 330 AM Sunday . Good boating conditions continue through much of the long term. Expect S to SW winds around 10 kt into mid week, with gusts to around 15 kt each afternoon as the sea breeze develops and differential heating tightens the gradient a bit locally. The Bermuda high begins to strengthen offshore mid to late week with southerly winds increasing to 10-15 kt with gusts up to 20 kt late Wednesday and Thursday. Seas persist around 2 ft through Tuesday, then build to 2-3 ft Wednesday and Thursday.
