Area Forecast Discussion National Weather Service Wilmington NC 945 PM EDT Thu Jun 4 2020

SYNOPSIS. Moisture from the south will begin to fuel scattered showers and thunderstorms through Sunday. A cold front will cross the coast late Sunday, bringing slightly cooler air into the region Monday and Tuesday, with lower chances for showers and storms. Rain chances increase by midweek as temperatures rise.

UPDATE. Latest radar shows development of showers and thunderstorms tonight have been slow. Adjusted timing of precipitation further into the overnight. Otherwise no major changes to the forecast tonight.

NEAR TERM /THROUGH FRIDAY NIGHT/. One more dry aftn expected today before rain chances increase for the remainder of the week. Moisture in both low and mid levels increases this evening from S to N, and in tandem with increasing mid-level shortwave energy approaching the area from the SW, will lead to a good chance of shra/tstms especially over coastal areas overnight through Fri morning. After potentially a brief break later in the morning/midday Fri, with sfc dewpoints above 70 and weak troughing aloft, environment is favorable for scattered aftn TSTMs. Not expecting any severe wx due to weak parameters like shear. Chances for rain then diminish through Fri night.

SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/. The mid levels will feature a modest trough in place which has an attendant cold front. This front will push south and east offshore slowly through the period. The front will get active on a daily basis with good chance pops Saturday and more modest values Sunday. Highs will be in the middle to upper 80s Saturday cooling slightly Sunday with overnight lows just a notch or two above normal.

LONG TERM /MONDAY THROUGH THURSDAY/. A highly amplified Omega pattern develops at the mid levels through the period as what remains of Cristobal meshes with a mid level trough across the upper Mississippi Valley. A deep cutoff low will develop in the Atlantic leaving a sharp ridge in between the aforementioned features. At the surface high pressure anchored by the sharp ridge will be in control most of the period from the northeast. The first couple of days should be dry then pops inch back into the forecast as the long since passed front drifts back to the north possibly reinforced late by a front from a passing trough. Temperatures will be a little on the cool side with the northeast flow but overall not much deviation from normal.

AVIATION /02Z FRIDAY THROUGH TUESDAY/. VFR for much of the next 3 hours, then moisture increasing from the south will help bring VCTS/VCSH and CB after closer to 03Z for SC terminals and 06z for NC terminals. MVFR ceilings possible as chances increase for thunderstorms and vicinity CB. Lingering MVFR may continue after sunrise, but VFR returns Friday afternoon.

Extended Outlook . Increasing moisture will bring thunderstorms Friday afternoon through mid week with varying flight restrictions.

MARINE. SSW flow continues tonight through Fri night with high pressure anchored well offshore. Speeds in the 10-15 kt range increase to 15- 20 kt Fri, with occasional gusts up to 25 kt especially over the NC coastal waters. No swell component anticipated during this timeframe, with just persistent 2-3 ft 4-5 second S waves tonight increasing to 3-5 ft at 5-6 seconds Fri into Fri night.

A southwest flow on the higher end of a 10-15 knot range will be in place Saturday and into early Sunday ahead of a front. The front will basically drift across the waters Sunday leading to erratic winds but still mostly southwest. Finally a northeast to mostly easterly flow will develop and persist into next week. The prolonged nature of the southwest fetch early may allow some six foot seas to develop across the outer waters thus representing the highest values of the period. Otherwise 2-4 feet seas will suffice.

ILM WATCHES/WARNINGS/ADVISORIES. SC . Beach Hazards Statement from 6 AM EDT Friday through Friday evening for SCZ054-056. NC . Beach Hazards Statement from 6 AM EDT Friday through Friday evening for NCZ106-108. Coastal Flood Advisory until midnight EDT tonight for NCZ107. MARINE . None.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

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