Synopsis for coastal waters from surf city north carolina to south santee river south carolina out to 20 nautical miles.. High pressure will expand across the western atlantic today through the weekend. The remnant low of former tropical storm beta will move northeast along a developing warm front, bringing modest onshore winds and a chance of showers. A cold front will approach from the west late Monday.

Area Forecast Discussion National Weather Service Wilmington NC 723 AM EDT Thu Sep 24 2020

SYNOPSIS. Temperatures will warm and humidity will increase as high pressure pushes offshore. Moisture from the remnants of Beta will increase rain chances from late tonight through Saturday morning. Mainly dry for the remainder of the weekend with temps above normal through Monday. A cold frontal passage with scattered showers late Mon will bring temps back to normal. A more powerful cold front will push across midweek next week followed by below normal temps.

NEAR TERM /THROUGH FRIDAY/. Former Tropical Storm Beta is located across Mississippi. Dense mid and high clouds extend east and northeast of the low and cover the Carolinas this morning. The south edge of these clouds may actually lift through part of our area later today, allowing a few hours of sunshine to develop south of a developing warm front. Southerly low level flow developing behind departing high pressure now well offshore will advect dewpoints in the 60s back across the area today. Afternoon cumulus clouds developing near the coast won't be able to grow substantially as there is still a solid inversion in place around 6500-7000 feet AGL that will cap these clouds off. GFS and NAM MOS highs have run a couple degrees too warm the last two days, so I'm going to undercut them slightly today with forecast highs of 77-80, warmest near the Santee River inland from the coast.

Mid and upper level moisture should continue to deepen with time tonight, and some light showers could break out as early as 10 pm west of I-95, but more likely after midnight as it will take time to erode lingering dry air between 850-700 mb left from the strong upper ridging of the past few days. Widespread isentropic lift (strongest at 305K-310K) should develop within the deepening moisture on Friday, joined by upright convection during the afternoon as CAPE grows to around 1000 J/kg. Precipitable water values rising to 2.0 inches and the potential for training storm cells argue for at least some potential flood threat developing Friday, especially inland. 0-1km helicity growing toward 200 m^2/s^s even implies the potential for rotation and a possible tornado threat. As a consequence, WPC has collaborated a Day 2 'slight risk' for excessive rainfall across our area, and SPC has us outlooked in a 'marginal risk' for severe weather Friday.

SHORT TERM /FRIDAY NIGHT THROUGH SATURDAY NIGHT/. Rain chances with isolated tstorms will peak Fri night thru Sat morning. This associated with moisture associated with Beta remnants pushing off to the NE, with Beta remaining NW of the FA, aided by a mid-level s/w trof. The other pcpn process will come from isentropic lift and a frontal boundary draped NE-SW across portions of the FA. Have increased the QPF for this pcpn time-line based on the 2 pcpn processes along with the latest WPC Guidance and portions of the FA now in Marginal/Slight categories for excessive pcpn thru Sat morning. Look for improving sky conditions Sat aftn and night with Max temps Sat aftn likely to eclipse 80 most locations as subsidence aloft in the wake of the upper s/w trof dominates thru Sat night. This seen with RH GFS model time height series for various locations across the FA. The NAM, not preferred, continues to be slower than the GFS/European with the ejection of the mid-level s/w trof eastward and thus the slower end to the pcpn by late Sat. Min temps each night will run atleast a Cat (5+ degrees) above normal.

LONG TERM /SUNDAY THROUGH WEDNESDAY/. Mid-level ridging and weak sfc high pressure will dominate Sun with what's left of the front from Sat pretty much dissipating altogether by Sun. Should see a good dose of insolation with highs being fcst on the hier side of guidance, ie. mid 80s. Weak sea breeze boundary may be enough for low chance POPs for showers and maybe an isolated tstorm Sun aftn. Otherwise, the next chance for convection will come on Mon as the flow aloft really begins to sharpen and amplify southward. A sfc cold front is poised to push thru Mon night, and will be accompanied by 20 to 30 POPs in the form of showers. Enough instability will become avbl to include isolated/slight chance for tstorms during the day Monday along a pre-frontal trof. The lagging mid-level closed low over the Gulf Coast States will open up and get pulled off to the NE by the expanding westerlies aloft. This may enhance pcpn activity well ahead of this front Mon, ie. along a sfc pre-frontal trof, more-so than what guidance is dictating. Otherwise, after FROPA Mon night, look for subsidence and drying thruout the atm column thru Tue. CAA will not be a factor until a much stronger cold frontal passage, albeit a dry one, during Wed. In it's wake, finally some CAA as Canadian High pressure drops SSE-ward from Central Canada in response to the longwave and deep upper trof becoming the dominate feature across the U.S. east of the Mississippi River Valley.

AVIATION /12Z THURSDAY THROUGH MONDAY/. VFR conditions will continue for the 12Z TAF period. Increasing moisture from the west will lead to cirrus thickening into a mid-level cloud deck during the day. Some low level moisture arriving during the afternoon should lead to a scattered to occasionally broken 3500-4500 foot AGL deck of cumulus along the coast, but a sharp temperature inversion should cap these clouds off around 7000 feet AGL. After 03Z, light rain chances may begin to increase inland for the KFLO and KLBT airports, but with VFR conditions continuing.

Extended Outlook . Spotty MVFR conditions Friday and Saturday due to scattered showers and isolated thunderstorms.

MARINE. Today through Friday . High pressure is centered midway between the South Carolina coast and Bermuda, and should strengthen over the next couple of days as it moves farther out to sea. The remnant low from former Tropical Storm Beta is located over Mississippi and will move into the southern Appalachians Friday. Falling pressures today across the interior coastal plain along a developing warm front will cause wind directions to back from southwest this morning to southeast by this evening. Wind speeds 10 kt or less today should increase to 10-15 kt tonight into Friday. Scattered showers and a few thunderstorms are expected Friday.

Friday Night through Monday . Moisture associated with the passage of Beta remnants and a coastal front/trof that develops just onshore prior to Fri night, will result in scattered showers and tstorms Fri night thru late Sat morning. This will also tighten the sfc pg with SSE-S winds around 15 kt with gusts up to 20 kt Fri night thru midday Sat. The gradient will relax late Sat thru Sun with the Atlantic sfc ridge axis dropping south of the waters. This will veer winds to the SW Sat night thru Sun and with a relaxed sfc pg, windspeeds will run 5 to 10 kt. Ahead of a cold front Mon, the sfc pg will tighten, resulting in SW winds increasing to near 15 kt. Seas will peak at 3 to 4 ft Fri night into Sat then subside to 2 to occasionally 3 ft Sat night thru Sun. With increasing SW winds Mon, look for seas to range between 2 and 4 ft. For the most part wind driven waves at 4 to 6 second periods will dominate the seas. However, a slowly dissipating inverted sfc trof, moving along the periphery of Atlantic High, will reach off Florida East Coast Mon. It may be enough to generate a 7 to 9 second period ESE swell that infiltrates the area waters later Sun into Mon.

ILM WATCHES/WARNINGS/ADVISORIES. SC . None. NC . Coastal Flood Advisory from 3 PM this afternoon to 6 PM EDT this evening for NCZ107. MARINE . None.
