Area Forecast Discussion National Weather Service Wilmington NC 1243 PM EDT Thu Jun 15 2017 .SYNOPSIS... Afternoon and evening showers and thunderstorms are expected across most of the area through Friday. High pressure will try to reassert itself later in the weekend, as a trough is reinforced to our west. A cold front will approach from the northwest early next week, likely increasing the coverage of showers and thunderstorms once again. && .NEAR TERM /THROUGH TONIGHT/... As of 1000 AM Thursday...The Forecast Area will be under the influence of weak subsidence in the wake of a mid-level shortwave trough which has exited the coast this morning. Considerable cloud cover have begun to erode, but the clouds earlier this morning have delayed strong heating. Given the factors above, we should not see much if any shower and thunderstorm development for the next couple hours or so. The airmass will be very similar to Wed. Precipitable water values will be near 2 inches. Mixed layer CAPE values will be between 1500 and 2500 J/kg. An inverted-V profile suggests the deepest updrafts will have the potential for strong to possibly severe wind gusts. Storm motions will be slow and with very high moisture content in the column, the potential for significant ponding is fairly high as a relatively quick 1 to 2 inches of rain in a particular community is certainly possible. In addition to residual outflow boundaries from previous convection, thunderstorms may develop along the convergent seabreeze boundary which will again be pinned relatively close to the coast. The Piedmont trough will be another boundary where convection is likely to develop. The back door cold front will remain well N of the area through the period. The greatest coverage of showers and thunderstorms is expected later this afternoon and through the first part of tonight. However, thunderstorms that develop along the seabreeze may develop by mid afternoon. 850mb temps will again be around 16C and with W/NW (downslope) mid-level flow, high temps should be similar to Wed, mainly lower 90s, although spotty mid 90s inland are expected. The beaches will be coolest, mid and upper 80s. Lows tonight will be in the lower to mid 70s. && .SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/... As of 330 AM Thursday...Unsettled conditions will persist through the short term period as a weakness or troughing remains across the southeast at the mid levels. As usual this time of year the Piedmont Trough, sea breeze and numerous boundaries will provide low level support for convection as will the precipitable water values that consistently hover around two inches. The challenge with this forecast is determining when the "highest" pops occur. Saturday seems to have a deeper southerly flow which may keep the inland trough more to the west leaving the sea breeze and residual boundaries, therefore Friday seems to be the best chance and we are maintaining high chance to likely pops with slightly lower values Saturday. Convection cannot be ruled out for the overnight periods as well. NO real surprises from a temperature perspective with highs in the upper 80s to lower 90s and overnight lows well into the 70s. && .LONG TERM /SUNDAY THROUGH WEDNESDAY/... As of 300 PM Wednesday...At 500 mb the area will be in between two ridges. One centered in the Atlantic and the other over the American southwest. The GFS and the ECMWF are similar in this pattern with the GFS showing a deeper trough Monday into Wednesday. At the surface, a frontal boundary will move into the eastern Carolinas on Tuesday and stall over the area on Wednesday. Precipitable waters are expected to be increase and approach 2 inches. Convection is possible each day with meso-scale forcing be through primary focus through early Monday. Synoptic forcing will increase with the slow moving cold front on Tuesday and Wednesday evening thought it will be in the weakening phase. Temperatures will be near normal with temperatures around 90 to middle to upper 80s at the coast. Lows will be in the low to mid 70s each day. && .AVIATION /18Z THURSDAY THROUGH TUESDAY/... As of 18Z...Typical summertime weather regime in place will yield showers and thunderstorms with the greatest coverage of convection expected mid and late afternoon through early to mid eve. Thunderstorms will be slow movers and have the potential for MVFR or lower ceilings and visibility in heavy rain. The risk for flight restrictions appears lowest at KCRE and KMYR, but will still carry a tempo group, but over a shorter duration here. The convection should dwindle late eve and overnight. Have added MVFR stratus at the coastal terminals near and after sunrise, otherwise VFR during this time. The potential for reduced visibility and ceilings in showers and thunderstorms will return Fri afternoon. Extended Outlook...The risk for flight restrictions due to mainly afternoon and eve thunderstorms will continue through the period. The probability for reduced ceilings and visibility in thunderstorms with heavy rain should be highest Fri and Sat and perhaps again Tue. && .MARINE... NEAR TERM /THROUGH TONIGHT/... As of 1000 AM Thursday...Bermuda high pressure offshore will remain the dominant feature once again today, maintaining return flow across the waters. This high will fluctuate in strength, initially weakening today before reasserting itself tonight, but this will create little change to otherwise uniform marine conditions through the period. SW winds of 10-15 kt will be gusty in the afternoon and eve hours due to the seabreeze circulation. Seas of 2 to 3 ft today will increase about a foot late day and tonight. A weak long period SE swell, on the order of 15+ seconds, is expected to arrive later today and then persist for a few days. SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/... As of 330 AM Thursday...Bermuda High Pressure will continue to be the dominate feature across the coastal waters through the period. Some enhanced low level jetting may increase winds late in the period into a range of 15-20 knots otherwise the standard south to southeast flow of 10-15 knots will suffice. Significant seas will be 2-3 feet for the most part with a possible uptick late coinciding with the increase in wind speed. LONG TERM /SUNDAY THROUGH MONDAY/... As of 300 PM Wednesday...A break between a high pressure ridge centered over the Atlantic and a high pressure ridge over the American southwest. Winds are expected to be from the south at 10 to 15 knots and seas will run around 3 feet with and increase to 3 to 4 feet by Sunday afternoon and 3 to 5 feet on Monday. && .ILM WATCHES/WARNINGS/ADVISORIES...
