Area Forecast Discussion National Weather Service Wilmington NC 308 PM EDT Fri Jun 12 2020 .SYNOPSIS... Unsettled weather will continue into next week with a stalled front generating daily showers and thunderstorms. Rain chances will begin to diminish late next week as high pressure weakly builds into the region. && .NEAR TERM /THROUGH SATURDAY NIGHT/... Deep mid-level dry air to the west will try to spread over the region through tonight. Along with this dry air is some weak mid level subsidence, mainly over far inland areas. Closer to the coast the front, which likely sits just off the SC coast but along the NC coast, will continue generating convection into the evening. The difference in moisture across the front is impressive with precipitable water in excess of 2 inches east of the boundary dropping under 1.4 inches over areas west of the front. Cannot completely rule out some isolated convection through early evening for inland counties, given abundant low level moisture and diurnal instability, but the aforementioned environmental factors will limit activity. Favored locations for afternoon diurnal convection would be NC counties east if the I-95 corridor. Currently there is an enhanced area of low level convergence over eastern Brunswick County and which is tapping into the deep moisture. Rainfall rates have exceed 5 inches per hour at times, but overall activity is weakening as the front shifts ever so slowly east and drier mid-level air moves closer. Nocturnal marine convection along the front is expected with showers and isolated thunderstorms occasionally moving onshore, especially for coastal NC. Front is nudged offshore by mid-level trough and surface high building south from Canada. Surface and mid-levels are really devoid of any features that would help encourage the front to move farther off the coast. Thus the boundary ends up lingering along the coast Sat and Sat night. Mid-level dry air and lack of strong forcing leads to a day that is more dry than wet for most areas. Still think there will be some convection around, especially closer to the coast (and the stalled boundary). However, a drier day compared to today is expected for most locations. Front lingers off the coast Sat night, but may start trying to move back onshore as surface to the north high migrates east across New England. On Sat temperatures will run below climo. Inland areas should end up within a few degrees of climo, but along the coast where clouds will be more substantial, highs will likely end up several degrees below climo. Lows will run near to slightly above climo, mostly due to abundant cloud cover and elevated low level moisture. && .SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/... A cold front will slide off the coast on Saturday and stall just offshore providing an axis of lift, especially near the coastal areas of NC and SC. An upper-level low will move southward during the day on Sunday as it becomes separated from the polar jet, lifting into southern Canada. Southwesterly flow around the southern extent of the disturbance will bring an elongated fetch of moisture into the Carolinas. These ingredients will combine to create an environment favorable for the development of isolated showers and storms. Soundings do not support the development of severe weather, but isolated areas of heavy downpours are possible. The cutoff low will settle over the southern Appalachians on Monday and southwest flow will continue and intensify as the height fall gradients increase over the Carolinas. Meanwhile, surface high pressure will develop over the northeastern CONUS and create a wedge of high pressure over the Mid-Atlantic region. This will lead to strong isentropic lift and the development of widespread showers. Elevated instability could help to create isolated areas of heavy downpours. Showers continue into Monday night with weak intrusion of dry air and dwindling instability leading to a significant decrease in shower coverage. && .LONG TERM /TUESDAY THROUGH FRIDAY/... Showers will likely continue on Tuesday with a slight decrease in coverage as weak dry air intrusion in the mid-levels makes its way into the area. The upper-low will begin to move away from the coast on Wednesday along with the modification of the wedge of high pressure. This will weaken our surface features and lead to a decrease in our available moisture. This slow drying trend continues into Thursday and Friday with the air mass returning to near normal temperatures. Some afternoon chances of storms along the sea breeze are possible, but otherwise, the organized rain-makers will be exiting to the NE through Friday. && .AVIATION /19Z FRIDAY THROUGH WEDNESDAY/... A cold front is hovering essentially right over the Carolina coast, bringing widespread showers and storms to the Cape Fear region. As a result, MVFR conditions dominate the coastal area, with a few brief pockets of IFR/LIFR in heavier rain. VFR is starting to make more of an appearance inland as drier air filters in behind the cold front, though a scattered cloud deck of 2500-3000ft still lingers back near KLBT and KFLO. Associated showers and storms with the front are slowly pushing out to the Atlantic. While KCRE and KMYR have dried out more recently, KILM can still expect plenty more rain over the next few hours. Widespread rain tapers off late this evening, leaving a few scattered showers behind it. MVFR still lingers throughout the overnight hours, but dry air looks to infiltrate the column more towards the end of the 18Z TAF period, bringing us back to VFR finally. Winds generally back towards the northeast tonight into tomorrow morning. Extended Outlook...Frontal boundary over the area late Friday night will provide continued pcpn chances and shifting winds. Expect daily brief periods of flight restrictions ranging from early morning fog, low stratus, and late morning and afternoon showers & thunderstorms going into the weekend and early next week. && .MARINE... Although weather over the waters will be rather unsettled through Sat night, the marine conditions do not appear to be much of a concern. The surface boundary stalled in the area will keep the pressure gradient weak into Sat. The weak gradient will keep winds, which will generally be east to southeast, under 10 kt into Sat. The front moves a little farther off the coast Sat opening the door for a period of enhanced northeast winds Sat into Sat night as the high tries to nose south. Speeds may briefly hit 15 kt late Sat before dropping back closer to 10 kt and becoming more easterly late Sat night. Seas will remain wind dominated with 2 to 3 ft in either a southeast or easterly wind wave around 5 seconds. High pressure will settle over the Northeast US and bring weak onshore winds beginning on Sunday. Onshore winds at around 10 knots will continue into early next week with a brief increase to 10-15 knots as low pressure attempts to develop on Tuesday. Waves will maintain 2-3 feet through the period, becoming 2-4 feet early next week. Winds veer and become offshore by Thursday at less than 10 knots. There is likely to be no significant swell for concern during this period. The main threat for mariners will be the chance for afternoon and evening thunderstorms each day. Dry air finally makes it into the Carolinas late next week. && .ILM WATCHES/WARNINGS/ADVISORIES... SC...None. NC...None.
