Area Forecast Discussion National Weather Service Wilmington NC 1230 PM EDT Tue Aug 11 2020

SYNOPSIS. High pressure extending westward into the Carolinas from the central Atlantic will maintain light south winds along with seasonably warm and humid conditions. Isolated to scattered thunderstorms can be expected each day.

UPDATE. No major changes made with this update.

NEAR TERM /THROUGH WEDNESDAY/. Late summer regime represented well again today, an atmosphere weakly forced with light steering wind and precipitable water at 2" or better, could again bring excessive water woes, localized, not widespread, as pulse-type convection is slated to move slow if at all today. Low level convergence should do the trick after 16z, after-which, self perpetuating pulse convection from peripheral outflows should keep SHRA/TSRAs bubbling up through 23z, mainly the coastal interior and central corridor zones coincident with zone of favorable convergence and subsequent meso-boundaries.

Max-T right about average for August 11th/12th, while Min-T to run several degrees above average.

Wednesday brings similar conditions, new convection by afternoon, while steering flow guides storms slowly N-NNW, plenty enough column vapor to fuel storms. No significant changes in T/Td winds and RH Wednesday, the biggest change is a slightly deeper and backed S-SSE flow aloft to guide convection slowly north Wednesday.

SHORT TERM /WEDNESDAY NIGHT THROUGH THURSDAY NIGHT/. A weak upper-level ridge will take shape offshore on Wednesday night. Weak troughing and associated shortwave will make its way into the Carolinas on Thursday. Widespread thunderstorm coverage will likely result with severe weather unlikely due to the weak wind field. Given the continued energy, storms are likely to persist into the early evening. With the expected cloud cover, highs are likely to remain in the upper 80s which will be a welcome break from the typical 90+ temperatures of mid-August. Overnight lows will remain in the upper 70s to near 80 with the oppressive humidity.

LONG TERM /FRIDAY THROUGH MONDAY/. Upper-level flow will become split between two 500-mb ridges by late week. An upper-level high over the desert southwest and another ridge over the North Atlantic will provide a crevasse of weak troughing over the eastern US. Elevated thunderstorm coverage is expected on Friday with a weak shortwave approaching the area along with an associated stationary front. Upper ridge over the Atlantic will begin to break down on Saturday allowing the stationary front to slowly progress eastward. The weak frontal boundary will make its way through the area on Sunday bringing early morning showers and widespread coverage of afternoon thunderstorms. Early next week the pattern becomes more uncertain according to various model ensembles. A large blocking ridge over the western US will provide deep NW flow over the central US. While this will promote high pressure building into the region, the perturbations in the upper-flow could lead to days with elevated thunderstorm coverage. In short, an unsettled period should be expected into next week.

AVIATION /18Z TUESDAY THROUGH SATURDAY/. Convection will have less coverage today, focused mainly on the Piedmont trough. Southerly winds today, mainly less than 10 kts. Convection will wane this evening with some isolated stratus/fog toward morning.

Extended Outlook . TSTMs, isolated to scattered will continue through the period. Patches of morning fog generally between 8z-11z should be expected, or localized MVFR stratus. Winds outside of TSTMs should remain light, and southerly.

MARINE.

Through Wednesday.. Steady as she goes, the light wind field pattern continues as broad high pressure covering the central Atlantic, extends westward into the Carolinas. Isolated marine showers within our 20 nm waters will bring a low-end risk of a waterspout, or isolated cloud to water strike, through early morning before inshore subsidence caps off additional CBs. Movement of showers this morning, SSW to NNE at 15 kt. The sea spectrum includes SSW waves every 3-4 seconds, mixed with SE waves every 9 seconds, totaling 2-3 feet this period. A radar update in encouraged before venturing out as a few TSTMs are expected to be trolling the waters on occasion.

Wednesday Night through Sunday.. Typical summertime southerly winds around 10 knots due to the dominating Bermuda high. Seas will generally be 2-3 feet with no significant swell. Elevated shower and thunderstorm chances are expected through late week. A brief period of offshore winds will develop with the passage of a weak frontal boundary on Sunday and Sunday night. The front will dissipate early next week, ushering in the return southerly winds around 10 knots.

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.
