Area Forecast Discussion National Weather Service Wilmington NC 1035 AM EST Sat Dec 14 2019
SYNOPSIS. Any lingering showers will move off to the northeast as wave of low pressure lifts away from area today. High pressure will build in from the northwest later this afternoon through Sunday. Southerly winds will bring warmer temperatures Monday and Tuesday, followed by increasing rain chances as another cold front crosses the area late Tuesday. Cold and dry weather will follow through the end of the week.
UPDATE. Forecast on target. Just adjusted area of lingering showers and other grids just a bit. Overall expect pcp over NC to move off to the NE and drier air to work its way in from the W-SW to E-NE through today. Water levels along the Cape Fear River will be high, but should remain just below any flood risk. SCA continues across the coastal waters for strong off shore winds and increasing seas.
NEAR TERM /THROUGH SUNDAY/. Latest sfc analysis shows a weak wave of low pressure along stalled frontal boundary over the area. Aloft, an upr-level trough and associated potent vort max are approaching the area. After a fairly dry overnight period the last few hours, chances for shras ramp back up through daybreak from west to east as the aforementioned vort max moves in from the west. Some moderate rain again possible, but not expecting any flash flooding. Also included a slight chance of thunder due to numerous lighting strikes noted off to the SW. Otherwise, just some patchy fog early this morning before the wind kicks up with and behind the pcpn. The SPS for patchy dense fog continues until 6AM. Conditions then dry out from W to E for mid/late morning, continuing for the remainder of the day. Dry wx will continue for tonight and Sun alongside decreasing clouds as sfc high pressure builds in from the W. High temps around 60 on average across the area both today and Sun.
SHORT TERM /SUNDAY NIGHT THROUGH MONDAY NIGHT/. The short term period will be mostly one of high pressure off the southeast coast. This and a developing storm system in the Mississippi Valley will keep a warm southerly flow in place. Highs Monday will be approaching 70. The storm system and or front will be near the NC/TN border by the end of the period with an increase in clouds. There could also be some light shower activity or sea fog across the waters. Lows Tuesday morning remain on the warm side well into the 50s.
LONG TERM /TUESDAY THROUGH FRIDAY/. A cold front will move across the area Tuesday. A rather quick hitting system with rainfall amounts of .25 to .50 possible. Beyond this a cold airmass will settle in for a couple of days of dry and cold conditions. Overnight lows will be the blustery middle 30s Wednesday followed by more conducive radiational conditions Thursday and Friday with lows below freezing moreso Thursday.
AVIATION /17Z SATURDAY THROUGH WEDNESDAY/. Stubborn IFR stratus will lift and scatter around TAF time. Look for gusty west winds this afternoon with falling dewpoints. Winds around 10 kts along the coast, lighter inland. A nice day in store for Sunday with VFR conditions and continued west winds.
Extended Outlook . VFR expected Sunday and Monday. Sub-VFR conditions could return Tuesday with a cold front passage. VFR Wednesday.
MARINE. A weak wave of low pressure currently tracking along a stalled frontal boundary will push off to the NE today. Behind it, CAA will increase through the day and allow for winds and seas to increase to Small Craft Advisory thresholds. The headline therefore continues as planned, ending tonight as marine conditions improve into the day Sun with sfc high pressure building in from the west. Otherwise, dense fog will continue early this morning until winds increase and a batch of rain moves in from the W later this morning.
Winds will be under transition early next week. A weak northeast flow will give way to a return south to southwesterly flow Monday and remain in place until a cold front moves across the waters overnight Tuesday into early Wednesday morning. Winds speeds during this time should be 15-20 knots max. An offshore flow will be in place Wednesday and continue through Thursday although magnitudes will be on the decrease. Regarding seas, expect 2-3 feet initially increasing to 3-6 feet during the peak of the winds Tuesday falling back in time after the front moves across.

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.
