(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus62 kilm 191903 afdilm area forecast discussion national weather service wilmington nc 303 pm edt Mon aug 19 2019 Synopsis Bermuda high and piedmont trough, typical of summertime, will persist into Friday. Showers and thunderstorms will be possible each afternoon and evening. A cold front will move into the area Friday then stall for the weekend. The front will be accompanied by an increase in unsettled weather. Near term through Tuesday night Despite moderate to strong surface-based instability this afternoon (li of -6 to -8c), dry air aloft has largely prohibited the vertical extent of cumulus, and subsequent development of showers and tstms. Some clustering of CU is occurring along the sea breeze boundary in horry and georgetown counties, portions of the pee dee region, as well as along the norther borders of bladen and pender counties, so these areas may see an isolated shower or TSTM before the afternoon is done. Otherwise, expect the late afternoon through overnight to be relatively quiet, with lows falling slowly into the mid 70s inland upper 70s coast. Widely scattered showers over the ocean overnight may scrape the shore after midnight, but confidence is too low to warrant adding small pops along the coast at this time. Deeper moisture will work its way across the forecast area in southwest flow aloft during the overnight hours. Surface-based instability will once again be plentiful, so shower and tstms activity should have an easier time developing than it has had today. Short term Wednesday through Thursday night Break in the mid-level ridge over the southeast during the period will allow for diurnal convection Wed and thu. The sea breeze and piedmont trough will be the main features, however guidance is showing a weak 5h shortwave riding up the west side of the ridge over the western atlantic late Wed into thu. This feature could lead to convection continuing well into Wed night before post wave subsidence and loss of surface based instability brings an end to convection after midnight. Not sold on it yet as the GFS has been inconsistent with it and the ec keeps it farther inland and weaker. Regardless of the feature or not, deep moisture will increase from wed to Thu which, combined with diurnal instability, will lead to an increase in storm coverage. Shower and thunderstorm coverage wed will be around 30% with potential for twice that (or more) come thu afternoon. Not going quite that high yet, but did increase pop a bit thu. Highs will be slightly above climo while lows will be well above climo. Long term Friday through Monday A cold front will move into the area late in the week and stall across the area over the weekend. The mid-level trough pushing the front south slips off the mid-atlantic coast sat, leaving the front hanging in the carolinas. Surface and mid-level high building in from the north-northwest eventually shift the boundary south, but not until next week. |
-widespread showers and thunderstorms Fri through mon. Stalled front may maintain convection well after sunset. -localized flooding could be a concern in areas that experience multiple rounds of heavy rain. -high temperatures near climo Fri will drop below climo sat through mon. -lows will be near to above climo. Aviation 19z Monday through Saturday ExpectVFR conditions to dominate through the valid TAF period. A lingering surface trough inland and sea breeze nearer the coast may spawn isolated storms this afternoon into the evening. Coverage should be limited so this is accounted for in the terminals with vcts. There is a small chance for MVFR ifr stratus or fog at inland terminals tonight but development of that will depend on debris clouds left from any convection that forms. Have left out of terminals ATTM due to low confidence in occurrence. Extended... MainlyVFR each day through Thursday. Exceptions... Brief MVFR ifr from tstorms each aftn thru early evening... And MVFR ifr from early morning fog and or low stratus each day mainly for the inland terminals. For Friday and Saturday, longer term MVFR ifr conditions possible as chances for showers and storms ramp up but vfr conditions should still be predominant. Marine Seabreeze-enhanced winds of around 15-18 kt will continue into the evening near shore. Otherwise, bermuda high is the main synoptic feature on the map in the near term, and will yield south-southwest winds of 10-15 kt overnight. There will be a small chance for isolated showers tstms developing overnight, however any development should die off once the morning sea breeze circulation kicks in on Tuesday. Southerly winds around 15 kt will persist on Tuesday. Seas will be comprised of southerly 2-3 ft waves around 4 seconds, and a 1-2 ft southeast swell at 9-10 seconds. Bermuda high and piedmont trough will maintain south to southwest flow through the end of the week. Speeds will vary from around 10 kt overnight and in the morning increasing to near 15 kt with higher gusts in the afternoon and evening. Seas 2 to 3 ft in the morning will build closer to 3 ft with occasional 4 ft late in the afternoon evening in response to the increase in winds. Seas will be dominated by a south to southwest wind wave, around 4 seconds, with some southeast swell component around 10 seconds developing late in the week. Ilm watches warnings advisories Sc...
