8/26/2020 The 7 day forecast is taking about 5 seconds to load but it will eventually load. NOAA is still working on it. 8/18/2020 NOAA continues to have trouble. Wind guest will occasionally be left off graphs. I am working with NOAA to resolve the issue. 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.. A weak pressure pattern will give way to increasing south winds ahead of a cold front. Marine visibility may be reduced in occasional heavy rain. The front will cross the coast early Wednesday, followed by cooler and drier high pressure for the remainder of the period. Advisory marine conditions are likely Tuesday night through early Wednesday.

Area Forecast Discussion National Weather Service Wilmington NC 1038 PM EDT Mon Sep 28 2020
SYNOPSIS. Increased rain chances through Tuesday night, with brief break possible midday Tuesday, ahead of a cold front. High pressure in wake of this front, will bring cooler and drier air through the remainder of the period into next weekend.
UPDATE. The coastal flood advisory for inland New Hanover was cancelled due to falling water level on the Cape Fear River.
NEAR TERM /THROUGH TUESDAY NIGHT/. Rain chances will increase through most of the period though a small decrease/break in the action may be slated for midday- afternoon Tuesday. Back to the very near term; there is an area of disturbed weather heading towards southern zones likely a small batch of coincident WAA and PVA. It is fairly well initialized by guidance and there is fair agreement that it should at least partially fizzle out as it encounters less low level baroclinicity. Towards the latter half of tonight rain chances ramp up along the coast especially NC as this is where the theta-E ridge appears to set up. And while these showers may be of moderate intensity at times they will still be lacking in deep layer forcing. In fact the overall coverage is still expected to wane towards midday. Later Tuesday afternoon attention then shifts to the west as a strongly forced convective line approaches. This line likely hits southern zones right around dark so it will be a bit challenged to encounter much SBCAPE. Models have quite a bit of QPF however, likely a testament to not only some lingering MLCAPE as well as the strength of the forcing due to the vigor of the incoming mid level trough. The entire area remains outlooked for a Marginal Risk by SPC. WPC indicates slight for excessive rainfall save for Marginal at the coast as most areas away from the beaches are at 200-300 percent normal QPF for the last 2 weeks.
SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/. Cold front will be making its way out of the area early Wednesday, with lingering rain possible in the morning before conditions dry considerably later in the day. Air column remains pretty dry Wednesday night into the weekend. Westerly winds develop behind the front at the surface, with a deep 500mb trough developing over the eastern US early Thursday. A second moisture limited cold front slated to move through the area Thursday night through early Friday that will usher in cooler weather for the weekend. Highs Wednesday in the low to mid 70s and in the upper 70s Thursday, with low temps mid to upper 50s.
LONG TERM /FRIDAY THROUGH MONDAY/. Front moves offshore early Friday with cool high pressure building in at the surface behind it, with upper trough still dominating the eastern US. 850 temps drop Friday night and temps 5 to 10 degrees below normal expected for the long term period, with highs between 70 and 75 degrees and lows in the low 50s. Most of the area expected to remain dry for the long term, with precipitable water values hovering around half an inch. Exception is slight chance pops along the coast late Sunday through Monday as some models are indicating a coastal low could form and move up the coast bringing some light rain.
AVIATION /03Z TUESDAY THROUGH SATURDAY/. High confidence for lower ceilings, visibilities, and chances for rain for all terminals over the next 24 hours. IFR tonight improving to MVFR/VFR by Tuesday afternoon.
Extended Outlook . Patchy fog possible each overnight and dissipating by mid morning. Showers become numerous through Wednesday with intermittent IFR possible. VFR late this week through the weekend.
MARINE. Through Tuesday night . Still pretty quiet but southerly winds will increase in speed heading into tonight probably less due to any change in surface gradient but rather a slight strengthening and better vertical aligning of the flow off the surface. The building wind will be more pronounced on Tuesday as both a cold front approaches to tighten the gradient and the deeper layer wind fields start to pick up ahead of an approaching shortwave. This system will be moderately strong and as it continues to draw nearer Tuesday night conditions should deteriorate to Advisory levels late in the day or at night with regard to seas even as wind speeds appear to fall a bit short of criteria. Six foot seas also do not appear to materialize over all zones. Given the marginal/spotty nature have not hoisted SCA just yet hoping that another model cycle will yield more insight as to when/where it will be needed.
Wednesday through Saturday . Conditions will be improving quickly early Wednesday as front moves across the coastal waters. West winds 10-15 kt Wednesday and Wednesday night weaken Thursday and become southwesterly under 10kts ahead of a second, but dry, cold front Thursday night. NW winds under 10 kts Friday strengthen to northerlies 10-15 kts on Saturday with tightened pressure gradient around inland surface high. 4-6 ft seas early Wednesday will subside to 2-4 ft by Wednesday evening, with 2-3 ft seas in place for Thursday through Saturday. Seas combination of a 1-3 ft SE swell and a diminishing S wind wave, with N wind wave building on Saturday.
