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. |

Area Forecast Discussion National Weather Service Wilmington NC 536 PM EST Fri Jan 22 2021
SYNOPSIS. Building high pressure will bring a drying and cooling trend into the weekend. Another low pressure system will bring clouds and occasional rain on Monday, followed by another system later in the week.
NEAR TERM /THROUGH SATURDAY NIGHT/. Forecast soundings show a drying in the low to mid levels through evening but cirrus level moisture lingering until 00z. Thereafter deeper layer drying occurs as surface boundary sinks off to our south in zonal flow for completely clear sky for much of the night. CAA ongoing but in a very tempered fashion resulting in fairly seasonable lows. Cloudless sky to continue Saturday but with slightly bolstered CAA behind a weak shortwave. Pair this with weak mixing and temperatures take a chilly turn to the tune of about a category/5 degrees. Good but not idealized radiational cooling Saturday night (possibly a few knots of wind as well as a few predawn clouds AOA 3 km) should support low temperatures that are 5 degrees cooler than tonight's lows.
SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/. Considerable changes from the beginning of the short term period, early Sunday morning, to the end of the period, later Monday. Initially cold high pressure will be overhead providing ideal radiational conditions for a cold start, below freezing for most areas. The high will drift offshore as a complex frontal system takes shape to the southwest and moves across Monday afternoon. Guidance has shifted ever so slightly to the main forcing and precipitation shield southward so pops have been incrementally increased. Highs will go from the lower 50s Sunday to the lower to middle 60s Monday with lows Monday morning in the lower 40s or so.
LONG TERM /TUESDAY THROUGH FRIDAY/. Changeable conditions for the extended period as well as a cold front associated with the system Monday moves across late Tuesday. Before this a very warm day is in store Tuesday with most if not all areas seeing highs in the 70s. Even the laggard SuperBlend guidance is on board now but grudgingly still cooler than the guidance from the global models. Temperatures Wednesday and Thursday revert quickly to near or below normal. Finally a system with varying solutions moves across Thursday. Maintained the chance pops for this time.
AVIATION /00Z SATURDAY THROUGH WEDNESDAY/. VFR for area terminals over the next 24 hours with light south winds shifting to the northwest. Occasional gusts possible to 15-20kts Saturday afternoon ending after sunset.
Extended Outlook . VFR through Sunday. Worsening flight conditions expected Monday with rain, low clouds, and periodically reduced visibility. Another system mid to late week will bring reduced flight conditions.
MARINE. Through Saturday Night . A N to NW cold advection regime tonight, something that can often be supportive of advisory-worthy conditions in the cool season. And while a small portion of the forecast zones may deteriorate that far late tonight/Saturday morning it appears to be quite a bit less than over half of the 20nm zones, meaning no flags at this time. The evening/overnight crew can certainly reassess. Interestingly later Saturday despite a stronger sense of cool advection the overall gradient weakens allowing for a continuation of sub-advisory conditions, though less experienced mariners may well wait for a quieter day. The gradient and resulting winds will already commence an abating trend Saturday night. Sunday through Wednesday . A northeast flow initially will quickly transition to a return/onshore flow later Sunday as high pressure moves offshore. Later Monday into the day Tuesday a more significant southwest flow develops. This flow could see speeds in a 20-25 knot range for a period of time. This will allow seas to possibly build into headline criteria as well. By midweek an offshore flow is back in place which serves to dampen the seas also.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program. |
