(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus62 kilm 231939 afdilm area forecast discussion national weather service wilmington nc 339 pm edt Fri aug 23 2019 Synopsis Scattered thunderstorms will become more numerous this weekend as a front stalls in the area. The front will linger offshore early next week. A tropical low may track north up through the offshore waters of the southeast coast early next week, lifting off to the northeast through mid week. Near term through Saturday night Somewhat organized afternoon convection well underway inland should diminish in the late afternoon and early evening hours. There should be a lull for quite sometime. Guidance shows a line of convection coming down very late from the north with the long advertised cold front. The trend has been for only a glancing blow so I lowered pops some. Still expect good coverage of showers and thunderstorms Saturday from about 1800 utc onward. The front which will be bisecting the area by then (and who knows how distorted from convection and a possible sea breeze) should be the main focus. For Saturday night the front reorganizes and slowly pushes off the coast and along with it the higher pops. Short term Sunday through Monday night Main concern this period is the approaching cold front and chances for tropical cyclone formation off the coast of the carolinas. Latest model runs have a frontal boundary that will stall near or just offshore, which will bring increased chances for rain near and along the coast, with heaviest rainfall occurring along and east of the highway 17 corridor. Confidence is increasing that there is a good likelihood that a tropical system will be ongoing by Sunday into Monday and approaching the offshore waters, which will bring increasing rough seas, increased chances for enhanced rip current activity along area beaches, and heavy rainfall that could bring minor flooding for low lying and poor drainage areas. Cool weather on tap for most locations with cool air advection behind the frontal boundary pushing into place. Expect afternoon high temperatures to be near to roughly 5 degrees below normal for late august. Long term Tuesday through Thursday Low will lift off to the northeast through mid week allowing for some drying, but looks like another front will make its way into the carolinas tues into wed. This front may stall out along or near the coast as high pressure builds in behind it. This may keep unsettled weather, especially along the coast through mid to late week. Aviation 19z Friday through Wednesday Vfr conditions continue today with possible ifr for inland TAF sites |
after 06 utc as a frontal boundary slow moves through the area and increase the low-level moisture. Ifr stratus fog is a distinct possibility at that time for inland sites and MVFR restriction of visibilities are possible around sunrise. Showers tstms will be capable of producing brief MVFR ifr. Rain chances begin to increase late tonight as cold front begins to move into region. Extended... Unsettled weather with MVFR ifr possible into Saturday with frontal system in area. Front will likely move just off the coast into Sunday but lingering moisture likely to lead to additional restrictions. Also watching potential tropical system moving NE just off the coast into early next week. Confidence low on related specifics at this time. Marine The summer time flow (a southerly component to the winds) seemingly has only a few more hours in place as a cold front will be pushing across from the north sometime Saturday. The actual arrival time is more toward the morning but wind fields are weak and will become somewhat distorted during the daytime hours via convection and possibly a sea breeze. For this evening expect southerly winds around ten knots or so. Kind of a mix Saturday but overall expect a westerly flow then northeast Saturday night. Most speeds quite light as well. Significant seas will be reflective of the winds about 2-3 feet or so. Front expected to push into the offshore waters by Sunday. Forecast is highly dependent on track and possible development of tropical low which is forecast to move up through the offshore waters of the southeast coast late Sunday through Monday. The gradient should tighten enough to produce a stiffer northerly flow and, in return, an increase in seas. As it stands now, seas 3 ft or less Sat night into early Sun will increase as low makes its closest pass, possibly within 150 miles of the carolina coast, late Sun through Monday. Wave models shows seas up over 4 ft Sun night into mon, but this forecast could change depending on low. NHC has been forecasting a greater chc of development but much uncertainty still exists. This low will lift off to the northeast Mon night into tues with an off shore flow developing. Seas will diminish heading into mid week. Ilm watches warnings advisories Sc...
