Area Forecast Discussion National Weather Service Wilmington NC 735 PM EDT Mon Jul 6 2020

SYNOPSIS. Showers and thunderstorms will increase in coverage Tuesday through Thursday as low pressure across Georgia moves to the South Carolina coast. This low could acquire some tropical characteristics as it slides offshore and away from the area Thursday and Friday, while thunderstorm chances linger into the weekend as a front stalls across the area.

UPDATE. Blended high-res guidance looks well initialized against radar imagery showing rather widespread shower activity across southern South Carolina into Georgia. This activity should spread gradually northward tonight, reaching as far north as Lumberton, Whiteville, and Wilmington around or shortly after daybreak Tuesday. For this update, I have increased PoPs across South Carolina and delayed the timing of this wave of showers to match radar trends. No significant changes to temperatures or winds.

NEAR TERM /THROUGH TUESDAY NIGHT/. GOES-EAST satellite shows the low-pressure area over southern Georgia. This low has helped bring a couple of bands of showers and thunderstorms into South Carolina and to a lesser extent into southeast North Carolina with drier air aloft. The 12 UTC NAM, GFS, and ECMWF all show the low slowly wandering toward the Carolina coast and nearing the Cape Fear Wednesday night. The NAM is the strongest with most of the precipitation remaining off the coast, but the consensus is for heavier rain along the coast. The 12 UTC, GFS Ensemble probabilities have slightly lower on the probabilities of > 2? along the coast that the 06 UTC run. Therefore, the confidence that the low-pressure will pass over the area is high but confidence is low on the exact location for the heaviest rain. WPC shows the possibility of 2 to 4? of precipitation over the coastal counties with less inland. Currently, they are showing a marginal risk of flash flooding. A Flash Flood Watch may have to be issued later, but the confidence at this time is low.

With the cloud cover and rain, maximum temperatures are expected to be in the 82 to 84F range. Lows will range from the lower 70s inland to the middle 70s at the coast.

SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/. Low pressure over the Southeast US will slowly move northward toward the Carolinas on Wednesday and Thursday. A large shield of onshore flow and precipitation ahead of the low will advect a warm, tropical air mass over the area. Showers and isolated thunderstorms appear very likely on Wednesday, especially at peak heating. This system currently looks very disorganized in overall structure, so off and on precipitation is likely with heavy downpours having the potential to cause localized flooding. Shower chances continue overnight Wednesday into Thursday. On Thursday, we may see more scattered coverage in shower activity as the low ingests some slightly drier air. During the afternoon, peak heating should allow for the development of widespread showers and thunderstorms. Overnight, the low pressure will become absorbed in the upper-level flow ahead of a developing upper-level trough and race out of the area toward the northeast. With the departing low, a weak stationary front will stall over the area and be the focus for shower activity on Thursday evening.

LONG TERM /FRIDAY THROUGH MONDAY/. A weak frontal boundary will remain in the area with the exit of the low pressure system on Friday. This will be the focus for thunderstorm activity during the afternoon and remain in the area through the weekend. During this time we will return to our typical summer pattern with highs around 90 and afternoon storms possible. The upper-level trough and stationary front will hang around through early next week as shower and thunderstorm chances linger.

AVIATION /23Z MONDAY THROUGH SATURDAY/. Two cloud decks exist this evening: clouds at 2000-3000 feet consists of scattered to occasionally broken stratocumulus with thickening altostratus to cirrostratus aloft at 15k-25kft. Low pressure across interior Georgia will lift an area of showers north across the eastern Carolinas overnight, leading to better chances of MVFR ceilings developing beneath the precipitation. TEMPO shower chances are in the current TAF beginning by 06Z at FLO and MYR, spreading north to ILM by 10Z. Widespread showers and embedded t-storms with MVFR ceilings are expected during the day Tuesday as deep Gulf moisture will be brought north around the low.

Extended Outlook . Low pressure to track across the Carolinas during the mid-week period, and eventually up the Eastern Seaboard and across the NE States by the upcoming weekend. Expect widespread MVFR/IFR conditions late Tuesday night through Thursday night.

MARINE. With the low-pressure area slowly moving from southern Georgia this evening to the coastal Carolinas by early Wednesday, the winds will be from the south to south-southwest and running only 10 to 15 knots with seas of 2 to 3 feet and increasing by sunrise Wednesday. The wavewatch is showing an east-southeast swell of 1.5 feet every 8 to 9 seconds.

Low pressure currently over central Georgia will slowly move NE toward the NC/SC coast by Wednesday. This low pressure may develop into a tropical low on Wednesday or Thursday, but given the position of the low (over land), any development would be limited to a spin off low and any impacts should be well east or northeast of the area. Winds will remain 10-15 knots out of the SW through the majority of the period with little to no significant swell. This disturbance will bring showers and thunderstorms for the majority of the week as the low exits on Friday. A stalled front will remain in the area as the low progresses toward the North Atlantic next weekend bringing continued chances of thunderstorms. The stalled front may lead to an increase in the gradient winds next weekend as high pressure attempts to build from the west and an upper-level trough sits over the eastern US.

TIDES/COASTAL FLOODING. Minor coastal flooding is likely tonight along the lower Cape Fear River. Minor flooding is expected to occur between 10 PM and 1 AM. The current forecast is for the river level to peak at 5.8 feet around midnight.

ILM WATCHES/WARNINGS/ADVISORIES. SC . None. NC . Coastal Flood Advisory from 10 PM this evening to 1 AM EDT Tuesday for NCZ107. MARINE . None.
