Area Forecast Discussion National Weather Service Newport/Morehead City NC 925 PM EDT Fri Aug 7 2020

SYNOPSIS. A weak frontal boundary will linger well inland through tomorrow as a weak trough continues near the coast. The front will finally push offshore on Sunday with high pressure building in from the north.

NEAR TERM /UNTIL 6 AM SATURDAY MORNING/. As of 925 PM Fri . The line of strong storms over the coastal plain produced flooding across northern Duplin County where 4-5 inches of rain fell in a couple of hours time early this evening. In the past hour the storms have shown a weakening trend and have become more scattered in nature. Expect a continued weakening trend through 4Z when storms should dissipate with the loss of heating. Late tonight, we expect additional development over the coastal waters and coastline as the upper trough moves closer to the area. Expect lows once again in the low to mid 70s inland, and the upper 70s along the coast.

SHORT TERM /6 AM SATURDAY MORNING THROUGH 6 PM SATURDAY/. As of 250 PM Fri . Axis of the broad upper trough will be about overhead tomorrow, with some shortwave energy passing through as well. This will result in a similar day to the last few, with scattered to widespread areas of convection and heavy rainfall. Expecting good heating in the morning, which should lead to a strong sea breeze, which will likely help initiate convection fairly close to the coast, and propagate inland through the afternoon. Other, more scattered storms should fire inland as well. Similar severe and heavy rainfall parameters will continue with MUCAPE values possibly exceeding 3500 J/kg, though shear will be slightly less . only around 15 kts, with PWATs remaining at or above 2". This could lead to an isolated strong to severe storm, though the bigger threat looks to be heavy rainfall given recent rains.

LONG TERM /SATURDAY NIGHT THROUGH FRIDAY/. As of 300 PM Friday . Ridging aloft begins to build across the region Sunday, while at the surface typical NC weather pattern develops as an inland trough forms and high pressure offshore.

Saturday night . Persistent upper level trough pushes offshore Saturday night, as a weak stationary boundary finally moves eastward towards ENC Saturday night. Models continue to show good agreement with the boundary moving eastwards as a weak cold front late Saturday night into early Sunday morning with continued scattered shower and thunderstorm chances overnight.

Sunday through Friday . The persistent trough aloft will finally transition to a ridge Sunday leading to a W/NW flow briefly Sunday and Monday as high pressure builds in from the north . leading to limited coverage of showers and thunderstorms. Then the ridge builds further, resulting for the wind flow to become SW as the surface high transitions offshore. Typical NC weather pattern sets up Tuesday through most of the week with inland though at the surface and surface high extending over the region . leading to additional showers and thunderstorms.

In general during this period, expect high temperatures to be in the upper 80s to lower 90 inland, while along the coast temps will range in the mid to upper 80s. Overnight lows will be mainly in the low to mid 70s inland and upper 70 to around 80 degrees along the coast.

AVIATION /01Z SATURDAY THROUGH WEDNESDAY/. Short Term /through Saturday/ . As of 645 PM . A line of thunderstorms will impact the TAF sites through 3Z, then expecting focus for additional precipitation to shift to the coast overnight. While low stratus clouds and patchy fog have been occurring the past several early mornings, today's guidance was not sending out a strong signal for this occurring overnight. However, based on persistence and little change in the very moist airmass and expected radiational cooling, will forecast a period of MVFR conditions after 9Z. These conditions should improve to VFR by 14Z. Scattered thunderstorms will again be a concern in the afternoon and early evening Sat.

Long Term /Friday night through Monday/ . As of 145 PM Friday . VFR conditions continue through the TAF period, except during the early morning hours as fog/low stratus is expected to develop and during diurnally driven convection which can bring brief sub-VFR cats.

MARINE. Short Term /Through Tomorrow/ . As of 925 PM Friday . Good boating conditions will continue through tomorrow with winds out of the S 10 kts or less and seas 2-3 ft. However, isolated to scattered showers and thunderstorms will be a threat across the waters tonight and tomorrow morning.

Long Term /Friday through Monday/ . As of 300 AM Thursday . Good boating conditions continues through next week. Expect SW winds around 10 or less knots with winds shifting to the W/NW early Sunday morning as a cold front is approaching the coastal waters. Winds will become NE Sunday morning and will generally return southerly by Sunday afternoon and continue through the period. Seas will generally be 1-3 ft through the period.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
