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.

Area Forecast Discussion National Weather Service Wilmington NC 953 AM EST Thu Feb 27 2020
SYNOPSIS. Cooler and drier air will move into the area today bringing below- normal temperatures and breezy conditions through the weekend. Warm and humid conditions return early next week with increasing rain chances by mid-week.
UPDATE. Gusty NW winds continue this morning with forecast on track for sunny, cool and breezy day.
NEAR TERM /THROUGH FRIDAY/. The cold front is now well offshore and breezy west winds are advecting significantly chillier and drier air across the Carolinas. Wind gusts earlier this morning reached 38 mph in Florence, 32 mph in Myrtle Beach, and 31 mph in Wilmington. A dry atmospheric column should allow full sunshine today. Insolation will battle it out with cold advection and highs are expected to reach 52-55 degrees. Relative humidity values of 25-30 percent are expected by mid afternoon.
High pressure near the Texas Gulf coast will push a ridge axis across the Carolinas tonight. Winds will become light overnight with very good radiational cooling expected. Lows should fall to around freezing, except in the typical cold spots across pocosins and swamps of Pender, Bladen, and Brunswick counties where upper 20s are expected. This will be another night where advanced plant grow spurred by the very warm temperatures in January and early February may create problems for local agricultural interests. The ridge will shift offshore Friday and southwest winds should again become gusty during the day, with highs in the mid-upper 50s.
SHORT TERM /FRIDAY NIGHT THROUGH SATURDAY NIGHT/. A shortwave moving through the area on Friday night will lead to the development of widespread cloud cover, especially over NC. NW winds will increase as the shortwave moves through the area also. These two parameters will come together and keep low temperatures in the mid-30s overnight Friday into Saturday morning. Moisture is limited to the mid-levels and dry air near the surface will limit any precipitation although a few areas of sprinkles cannot be ruled out. Skies clear during the day on Saturday as the longwave trough overhead moves off to the east. Winds will continue into the afternoon while weakening in intensity over the area. High pressure previously stationed over the central Gulf of Mexico will slowly move overhead on Saturday night.
LONG TERM /SUNDAY THROUGH WEDNESDAY/. Sunday morning will likely be the coldest of the next 7 days with clear skies and dry conditions. Temperatures are likely to bottom out near 30. High pressure and clear skies dominated on Sunday. High pressure moves offshore on Monday and southerly flow returns bringing with it warm, moist air. This will lead to an increase in cloud cover on Monday night and SW winds. Upper-level pattern comes in-line with with the surface winds and deep layer moisture advection should lead to increased rain chances during the day on Tuesday, especially to the north and west of the area. The apex of this upper-level ridge will push eastward on Wednesday and bring the deep-layer moisture closer to the area. This will lead to increased rain chances Tuesday night into Wednesday. Warm air will surge northward on Thursday ahead of a cold front leading a developing low pressure system expected to develop over the central US. A lot will depend on the timing, intensity, and location of this low pressure system in future model runs, but the general trend seems likely. Warm and moist air returns early next week while rain chances and above-normal temperatures increase through mid-week.
AVIATION /14Z THURSDAY THROUGH MONDAY/. VFR conditions are here to stick around throughout the TAF period. West-northwest winds could gust to 20-25 knots through the early afternoon before tapering off. No low-level wind shear concerns to speak of. Lighter winds tonight.
Extended Outlook . A little shortwave moving through overnight Friday into Saturday morning will lower ceilings, but still remain in VFR. Next flight restrictions should occur sometime in the middle of next week.
MARINE. The cold front is now well offshore and breezy west winds will continue throughout the day. Wind gusts reached 37 knots out at the Frying Pan Shoals buoy, 35 knots in Southport, and 27 knots at Myrtle Beach overnight. Wind speeds should begin to die down by early afternoon and the Small Craft Advisory will end at 1 PM.
High pressure centered along the Texas Gulf coast will extend a ridge axis eastward and across the Carolinas tonight. This ridge will move offshore Friday, allowing winds to back to the southwest and increase to 15-20 knots during the day. At this time it appears Small Craft Advisory conditions won't develop although sea heights will build by 1-2 feet during the day.
Upper-level shortwave will move through the area Friday night into Saturday. This will cause a surge in offshore winds speeds at 15-20 knots with gusts to 25-30 knots. Seas will respond to near Small Craft Advisory levels, but largely 3-5 feet with an occasional 6. High pressure builds into the area Saturday night into Sunday and dominates the weather pattern through Monday. Increasing southerly winds develop on Monday night as the high pressure moves out to sea and warm, moist air returns to the area. Winds continue to increase through the middle of next week as the high stays stationed off to the east and low pressure develops over the central US. Small Craft conditions are likely to develop with such a consistent fetch of SSW winds. The exact timing is far from being nailed down, but look for marine conditions to begin deteriorating Tuesday through the remainder of the week.

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.
