Area Discussion for - Wilmington, NC

      (on/off)   Help   NOTE: mouseover dotted underlined text for definition

Fxus62 kilm 170539 afdilm area forecast discussion national weather service wilmington nc 1239 am est Thu jan 17 2019 Synopsis Cold high pressure will move offshore Thursday while weak low pressure on its heels brings a few showers early Friday. Strong low pressure passing west and north of the area this weekend will bring warming, and a good chance of rain Sunday as a cold front crosses the coast. Cold air will return early next week as canadian high pressure dives into the carolinas. Near term through today As of 10 pm Wednesday... Previous forecast remains on track; no major changes necessary with this update. Previous discussion... As of 300 pm Wednesday... Elongated ridge axis offshore overnight will be absorbed by second, larger area of high pressure extending south from the great lakes region. Gradient will remain weak with light to calm surface winds overnight. Flow just above the surface will be from the southwest, which will lead to a slight increase in low level moisture. Fog may become an issue early Thu due to good radiational cooling and the slight bump in moisture. Weak warm advection will lead to a slight bump in lows overnight with temps ranging from upper 20s to mid 30s. Larger high pressure centered to the north shifts east on thu, with low-level flow becoming southerly during the day. Gradient remains light, keeping flow weak, but there will be a definite shift to a warm advection regime tomorrow. Weak shortwave and resulting surface low emerging from the central plains will lift northeast, across the ky and oh valleys during the day. Associated cold front approaches from the west late in the day, accompanied by increasing moisture. Moisture will still be lacking however. Forecast soundings keep precipitable water well below 1 inch through tomorrow evening and subsidence layer around 800 mb will be tough to overcome. At this point do not anticipate much in the way of showers through the end of the period and will keep precip chances under 20% through thu. Highs will be near to slightly above climo on the back of increasing warm advection, mid to upper 50s. Short term tonight through Friday night As of 352 pm Wednesday... Massive vortex around northern ontario will help propel a short-wave ripple in the h5 flow across the coast late Thursday night. A brief period exists Thursday evening where enhanced column moisture and convergence could bring showers, with little measurable rainfall expectation. The system carries little cold air advection and overall the system does not disrupt a warming trend, but may delay it a bit as a weak cold front briefly dips across SE nc on Friday. Long term Saturday through Wednesday As of 352 pm Wednesday... Warming temperature trend prevails this weekend, bringing maximums well into the 60s, about 10 degrees above mid january normals. Pre-frontal, warm air advection Saturday will transition into frontal passage Sunday, in morning and off the coast in early afternoon. Will retain slight chance of a TSTM Sunday because the low-level convergence and dynamical support aloft should work in concert, and for what it may contribute, near maximum diurnal warmth in FROPA closer

to the coast. In question remains available instability. Frigid air invades again as canadian high pressure swoops into the carolinas. As the cold high approaches, we probably should expect widespread 20s next Tuesday morning, isolated teens. Aviation 06z Thursday through Monday As of 06z... A very weak surface trough is moving across the area otherwise skies are mostly clear and winds light to calm. Some fog has already formed and expect mostly MVFR br off and on mostly on toward daybreak.VFR conditions will develop shortly thereafter. Extended outlook... MainlyVFR until Saturday and into Sunday when MVFR conditions are possible in showers Saturday and due to cigs Sunday.VFR Monday. Marine Near term through Thursday ... as of 300 pm Wednesday... High pressure over the waters tonight will be absorbed by larger high centered over the great lake early thu. Gradient will remain weak into Thu afternoon, keeping speeds 10 kt or less. Direction will initially be from the north but as the high to the north shifts east, Thu afternoon, southerly flow will develop. Period ends with south to southwest flow over the waters, however speeds will remain under 10 kt. Seas will remain 2 ft or less through the period with an east- southeast swell being dominant. Short term Thursday night through Friday night ... as of 352 pm Wednesday... A cold front late Thursday night will bring winds from SW to W into Friday but no advisories expected as winds remain 15 kt with a few gusts up to 20 kt. Showers late Thursday night may enhance gusts locally, briefly. Because winds will be mainly offshore and swell has faded, wave heights will remain low this period. Long term Saturday through Monday ... as of 352 pm Wednesday... Worsening marine conditions can be expected beginning late in the day as a strong cold front approaches the waters, and SE winds mount to 20-25 knots Saturday night. As balmy gulf stream air encounters cool inshore waters, we may see sea fog late Saturday into Sunday along with rough and hazardous wave action. By Sunday s-ssw waves of 4-8 ft every 8-9 seconds will dominate waters. Sw-w winds Sunday will turn to NW Sunday night as cold air dives in, and advisories flags will continue. Ilm watches warnings advisories Sc... None. Nc... None. Marine... None. Synopsis... 08 near term... Iii mas short term... Mjc long term... Mjc aviation... Shk marine...

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.
