Area Forecast Discussion National Weather Service Wilmington NC 107 AM EST Sat Feb 22 2020

SYNOPSIS. Low pressure offshore from the Carolina coasts this morning will further intensify as it accelerates away from the mainland this afternoon through Saturday. Cold and dry Canadian high pressure will build in and dominate this weekend. A warm front will lift across the area early Monday bringing milder temperatures through Tuesday. A cold front will push across the region late Tuesday with cold and dry high pressure following for the mid week period.

UPDATE. No big changes necessary with the 10pm update . a Small Craft Advisory remains in effect until 7am.

NEAR TERM /THROUGH SUNDAY/. Below normal temps and clear skies to dominate through Saturday night. High pressure at the surface builds in by tomorrow and remains overhead throughout the near term period, with precipitable water values remaining less than 0.2". Current lingering clouds over coastal SE NC counties will clear out by early this evening. Main story will be how low temps will get tonight. ECM and GFS MOS guidance have lows dropping to low 20s tonight with decoupling at the surface. Other guidance, such as the RAP, HRRR, and NAM, keep a shallow mixed layer at the surface due to elevated boundary winds, with lows staying in the upper 20s/near 30 degrees. Best chance for decoupling will be for our far NW and N areas as the pressure gradient relaxes overnight and BL winds begin to weaken towards morning. Leaning more towards the warmer, but still freezing, solution for most of our area, but have only raised lows a couple of degrees as there's still a chance could see lows drop fast overnight. Beyond that, highs Saturday will be in the low to mid 50s, with lows Saturday night dropping to just below freezing.

SHORT TERM /SUNDAY NIGHT THROUGH MONDAY NIGHT/. High pressure continues to allow dry weather for Sunday with temperatures warming as southerly winds return to the Carolinas. A warm approaches the region Monday and brings high temperatures back into the 60s with increasing chances for rain. With little to no instability, no thunder is expected. Plenty of atmospheric moisture will be available, and moderate to heavy rain at times as front passes Monday night. Early indications show between 0.25" and 0.50" of rain expected Monday.

LONG TERM /TUESDAY THROUGH FRIDAY/. Cold frontal passage in the Tuesday/Wednesday timeframe will bring continued chances for light to moderate rainfall across the region. Warm air sector ahead of the front could see afternoon high temperatures rise into the upper 60s to near 70 for some locations, which is about 10 degrees above normal for late February. After the frontal passage, a return to dry conditions can be anticipated late next week with afternoon high temperatures returning to the low to mid 50s, which is slightly below normal.

AVIATION /06Z SATURDAY THROUGH WEDNESDAY/. VFR conditions expected throughout the 24 hr TAF Issuance Period. The broad center of cold and dry Canadian high pressure will become entrenched across the Southeast States today thru Sun. No cloudiness expected other than occasional thin jet stream cirrus. Winds generally N-NE around 6 kt becoming calm by dusk today. Coastal terminals may see a brief E-SE 5 kt wind this aftn before calm conditions set in after sunset.

Extended Outlook . VFR will persist through Sunday as the center of the high slowly moves off the Carolina coasts. Potential flight restrictions will increase early next week due to a WFP slated for Mon and a CFP late Tue.

MARINE. Today through Saturday Night: Small Craft Advisory conditions likely tonight into early tomorrow morning. North winds around 25kts with gusts in the low 30s over the next few hours will decrease into tonight, with winds around m15 kts gusts to 20 by morning and N winds less than 10 kts by late tomorrow afternoon through Saturday night. Seas 5 to 7 ft tonight decrease to 4-5 ft Saturday and lower further to 3-4 ft Saturday night, predominantly an 11s easterly swell.

Saturday Night through Friday: Quiet conditions for Sunday and Monday with waves around 2 to 3 feet from the east around 10 to 12 seconds. Waves steadily increase into Tuesday as the next series of fronts approach the offshore waters. Waves 4 to 7 feet possible with continued light easterly swell around 10 to 12 seconds and wind waves from the south at between 6 and 8 seconds Tuesday through the end of next week. The next chances for small craft concerns would be early to the middle of next week.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
