Marine Weather and Tides
Version 3.4 |
12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed. 10/9/2019 Updated the Marine Zones. 9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. |

Synopsis for coastal waters from surf city north carolina to south santee river south carolina out to 20 nautical miles.. High pressure will remain well offshore, and drift farther away through the period. A weak front will stall along the coast late tonight, while high pressure rebuilds off the mid-atlantic coast late in the week.

Area Forecast Discussion National Weather Service Wilmington NC 245 PM EDT Mon Jul 13 2020
SYNOPSIS. A few strong storms are possible through the afternoon into the evening. A ridge of high pressure will follow, building over the area through the week, maintaining hot and humid weather along with a few afternoon showers and thunderstorms. Storms could increase in coverage again during the weekend.
NEAR TERM /THROUGH TUESDAY NIGHT/. Scattered showers/tstms have initially focused near a weak trough/frontal boundary across the Pee Dee, but remain widely scattered elsewhere across the forecast area. A shortwave will push the boundary to the east through late afternoon, and expect most of the convection to die off after sunset, although a few rogue storms may hold on a few hours longer. There remains a risk for damaging wind gusts with the stronger storms. Dewpoints should fall a couple of degrees overnight behind the boundary, and low temps are expected to range from roughly 72 inland to 76 at the beaches. Geopotential heights will begin to rise across the area Tuesday as a ridge axis builds across the Tennessee River Valley. This will allow temps to once again surge into the low- mid 90s, and will also keep showers/tstms fairly isolated.
SHORT TERM /WEDNESDAY THROUGH WEDNESDAY NIGHT/. Heat will be the primary concern Wednesday afternoon with a ridge building aloft yielding another day with a heat index in the upper 90s into the lower 100s. Prospects for convection exist but will generally remain isolated, especially during the afternoon and evening with the sea breeze providing some lift. Otherwise weak surface ridging from the north will maintain control of the weather.
LONG TERM /THURSDAY THROUGH MONDAY/. Typical summer weather through the end of the week and into the weekend with high pressure setting up far off the NC coast by Saturday. This area of high pressure will reside off the NC coast through Sunday and Monday as well. A band of the subtropical ridge will be in place over the area Thu and Fri limiting convection to isolated chances each afternoon and evening. However, the subtropical ridge is shown to consolidate across the Central Plains Saturday and Sunday with a weakness developing overhead. As a result, diurnal convection is expected to become widely scattered to scattered with a little better support aloft.
AVIATION /18Z MONDAY THROUGH SATURDAY/. A fairly typical summer day with convection firing along the sea breeze boundary and inland trough this afternoon. Went with VCTS at this time, however thunder at the coastal terminals will be a decent bet between 19-22Z. Some ground fog possible tonight, particularly where any heavy rain may have fallen.
Extended Outlook . Brief MVFR/IFR conditions possible in scattered diurnal convection, however coverage should be 20 percent or less each day.
MARINE. Through Tuesday night . With a weak trough remaining just inland overnight, SW winds of 10-15 kt will prevail. The boundary may push just far enough to result in a wind shift to the N-NE Tuesday morning, but speeds would be 10 kt or less in weak gradient. Speeds will remain less than 10 kt through the afternoon, as the direction veers around to the SSE by late in the afternoon. The surface pressure field will remain weak across the waters Tuesday night. Winds speeds will be 10 kt or less, and generally out of the SE.
SE swells will remain the dominant wave, and are peaking today. They will subside to 3 feet tonight and 2 feet by Tuesday night, at a period of 6 seconds.
Otherwise, a very weak surface ridge from the north will affect the waters Wednesday and Thursday with light winds during that time. The ridge axis will become oriented nearly E-W as the center of high pressure takes residence off the NC by the end of the week. As a result the period of light onshore flow is expected to veer to a S-SW direction and increase a notch by the weekend. Seas will generally be in the 2-3 ft range and will be comprised of a weak east-southeast swell and weak higher frequency southeast wave which gradually becomes
