NWS Wilmington, NC wrote its last area forecast discussion before the first event at Jun 10, 9:18 AM EST, 1 hour 42 minutes earlier.
Area Forecast Discussion National Weather Service Wilmington NC 1018 AM EDT Sun Jun 10 2018 .SYNOPSIS... Scattered showers and thunderstorms today will form along and just inland from the coast, associated with weak low pressure moving into Cape Fear. Rain chances will increase Monday into Tuesday, as moisture increases and a cold front drops into the area. A trough of low pressure inland, will maintain shower and thunderstorm chances each day. Low pressure will deepen off the NC coast late next week. && .NEAR TERM /THROUGH TONIGHT/... As of 10 AM Sunday...Weak surface wave/trough moving up the coast today will enhance low level convergence across coastal NC. Anticipate showers and possibly a few thunderstorms developing during the next few hours as temps warm into the mid 80s. Dry air aloft will start spreading in from the west- northwest today, which may keep the bulk of the convection closer to the coast. Storms that do develop will be capable of producing significant rainfall given storm motions around 5 kt. Highs today will range from mid 80s along the coast to lower 90s inland. && .SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/... As of 343 PM Sunday...A 'wet early week' may aptly describe this period as both low-level convergence and precipitable water increase across NE SC and SE NC, as surface low pressure helps pool these features into the area. NCEP SREF Plume data shows dewpoints in the low 70s, and MUCAPE rising as high as 2500 j/kg Monday afternoon. GFS ensemble QPF plumes show several solutions of 1 inch plus rain amounts Monday afternoon through Tuesday AM in this window, PWATs may crest 2.00". The partial downslope wind flow Monday will bring temperatures into the 90s in many spots. Upper support may arrive from previous convection with MCV induced omega a good possibility, plenty CAPE to tap. The SPC has painted a 'marginal risk' that includes the Carolinas Monday. A stalled frontal boundary will help focus additional convection for Tuesday as well. Outflows, rain-cooled air, less downslope, and a cold front, will all help a bring a cooler daytime Tuesday compared to a very warm Monday. && .LONG TERM /WEDNESDAY THROUGH SATURDAY/... As of 300 PM Saturday...Weak mid-level pattern fluctuating between progressive and limited troughing for much of next week will transition to ridging for Fri and Sat. Deep tropical moisture lingers over the area into Fri with precipitable water ranging from 1.7 to 2 inches. Late in the week there starts to be significant disagreement with the location of mid-level features between the GFS and ECMWF. ECMWF has the 5h ridge firmly in place over the Southeast while the GFS has the center of the ridge farther north and west. The difference would be higher precip chances for the local area if the GFS is correct. However, given that the GFS is an outlier will trend the later parts of the forecast in the direction of the drier ECMWF/CMC solutions. Most solutions also show a backdoor cold front crossing the area late in the period, but given the time of year a clean frontal passage seems unlikely. However, it is something to keep an eye on. Temperatures will remain above climo through the period. && .AVIATION /14Z SUNDAY THROUGH THURSDAY/... As of 12Z...At KFLO/KLBT there is good confidence vsbys will improve to VFR by 13Z, but cigs will likely not improve to VFR until 13-14Z. Except for low confidence MVFR cigs from 14-16Z, there is good confidence of VFR for the remainder of the day with no precipitation at KFLO/KLBT. Coastal terminals through 14Z will be VFR. Showers will be developing by 14Z with best coverage near KILM. Will indicate tempo MVFR cigs all coastal terminals 14-17Z, with tempo SHRA at KILM/KCRE. IFR would be most likely KILM as will be a thunderstorm during this time. The sea breeze will kick in at KMYR/KCRE 16-17Z but possibly not until early afternoon at KILM due to the convection. Will continue VCSH into early afternoon, best confidence KILM. Convection becomes more isolated as the afternoon progresses as drier air moves in from the NW. KFLO/KLBT may have a better chance of convection during the evening. VFR this evening and overnight all terminals, except KFLO/KLBT which will have the threat of MVFR vsbys in fog by the pre-dawn hours. Extended Outlook...VFR with tempo MVFR associated with showers/isolated thunderstorms through Thur. Best chances for convection will be Mon evening and Tue. && .MARINE... NEAR TERM /THROUGH TONIGHT/... As of 10 AM Sunday...Light winds this morning will increase to around 10 kt for the afternoon with direction becoming southerly as weak surface wave moves across and then north of the area. Seas will range from 2 to 3 ft today. SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/... As of 343 AM Sunday...S-SW winds 11-16 kt this period with gusts at times to 20 kt, as low pressure generally remains inland of the waters. Variability in wind speed and direction can be expected Monday night, as a wave of low pressure rides NE along the coast. Showers and TSTMS will be out and about, some may be strong Monday. Radar updates are encouraged if venturing out. Gerling- Hanson wave vector plots show SSW waves 2-3 ft every 5-6 seconds to dominate spectrum, mixed with weak SE swell and a moderate S-SW chop. LONG TERM /WEDNESDAY THROUGH THURSDAY/... As of 300 PM Saturday...Bermuda High off the coast through the period will maintain southwest flow. Piedmont trough sets up Wed and Thu with a daily increase in southwest flow like in response to the trough. Speeds a solid 15 kt Wed and Thu. Seas will build to 3 to 4 ft in response to increasing southwest flow. && .ILM WATCHES/WARNINGS/ADVISORIES... SC...None. NC...None. MARINE...None. && NEAR TERM...III SHORT TERM...MJC LONG TERM...III AVIATION...MRR
