(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus62 kilm 180540 afdilm area forecast discussion national weather service wilmington nc 140 am edt Sun aug 18 2019 Synopsis A front will meander across the carolinas through Monday before slowly weakening into a surface trough. A cold front will move in from the northwest on Friday and will stall along the coast. Numerous showers and thunderstorms will continue through Sunday before the storm coverage becomes more scattered Monday through Saturday. Update Forecast appears to be in good shape. Rain is likely over for the western half of the area. Meanwhile areas along the coast will have rain return after this brief lull as low pressure currently over savannah river moves up the coast. 18z WRF hits the CAPE fear region pretty hard and kltx storm total rainfall shows this has been where the heaviest rain has occurred thus far. Short fused flood advisories appear likely overnight-but cannot rule out ff watch should upstream convection start congealing towards the WRF solution. Near term through Monday Main concern for the next 36 hours is the potential for heavy rain in developing showers and thunderstorms. Stationary front positioned over the carolinas has remained unchanged in position from 24 hours ago and is expected to change very little into Sunday with plenty of atmospheric moisture present, leading to humid conditions with chances for showers and thunderstorms mainly along and east of i-95, with coastal areas along the highway 17 corridor having an increased chance for precipitation. Model forecasts are in good agreement and confidence is high for showers and thunderstorms to produce heavy rain at times with the potential for minor flooding, especially for low lying or poor drainage locations, if storms continue to pass over the same areas. Cloud cover along the stationary boundary will lead to a lack of sunshine at times with cooler weather. Patchy fog is possible with abundant moisture and high relative humidities overnight tonight and into Sunday morning. Afternoon highs through Sunday afternoon will be near to slightly below average for this time of year in the mid to upper 80s and just above 90 in some locations. Short term Monday night The frontal boundary that has focused the precipitation the last few days will weaken to a trough, and the deeper moisture will be shunted off the coast. At the surface, southwest winds will continue with a sea-breeze developing late Monday morning and continue into the evening. The precipitable water falls from +2" to 1.75" and the models are indicating convection to continue but be more scattered in coverage. Monday appears to have the smallest chance of showers and thunderstorms for the week. High temperatures will range from the middle 90s west of interstate 95 to the mid and upper 80s at the beaches. Lows on Monday night will fall to the lower 70s inland to the middle 70s at the coast. Long term Tuesday through Saturday The region will continue to stay in the break of the 500 mb high-pressure ridge through the period. At 850 mb, streamlines show southwest flow continuing and below 2.5km a sea-breeze develops each day. The precipitable waters that were ~1.75"on Monday will rebound |
to more normal values which are just above 2". Models continue to show a chance of showers and thunderstorms each day. As a frontal boundary approaches the area on Friday and stalls across the area on Saturday an increase in coverage of thunderstorms is likely. High temperatures this period will range from the lower 90s inland to mid to upper 80s at the beaches Tuesday through Friday. Saturday will be slightly cooler with highs in the upper 80s inland and middle 80s at the immediate beaches. Low temperatures will be from the lower 70s west of interstate 95 to the middle 70s in the coastal counties. Aviation 06z Sunday through Thursday Tropical low pressure system will ride northward along a stationary front stalled just onshore early this morning. This will pull an area of showers and thunderstorms offshore by later this morning, as the stationary front will slide offshore and NW winds behind this front will usher in slightly cooler air and morning stratus. Expect MVFR ifr across much of the area, improving toVFR soon thereafter. With the front positioned slightly offshore, there should only be a few clouds around this afternoon with a couple of isolated storms along the sea breeze. Extended... Moisture will move back in on Monday leading to enhanced chances of rain and morning stratus br. Afternoon showers and storms possible through much of the extended period along with morning stratus br. Marine Main concern for the next 36 hours is developing thunderstorms offshore, as well as concerns for small craft with gusts up to 25 kts at times. Waves out of the south to southwest at significant heights of 4 to 6 feet at 7 seconds through tonight decreasing to 3 to 5 feet Sunday. Light swell from the southeast around 10 seconds. Southwest winds for the next 36 hours from the southwest between 5 and 15 mph with gusts approaching 25 kts at times, especially during the afternoon. Showers and thunderstorms likely as a stationary front inland allows for unstable weather. Waves and winds could be locally higher in thunderstorms. Monday through Thursday the coastal waters will continue be on the north side of the bermuda high. The surface high-pressure field's orientation will allow for southwest winds 10 knots or less with a southerly wind developing close to the coast as the sea-breeze develops through early Friday with an increase in winds to 10 to 15 knots late Friday into Saturday as a frontal boundary approaches the coast and stalls. Seas are expected to be 3 feet on Monday and 2 to 3 feet Tuesday through Thursday. Wave components will be a southwest wind-wave between 2 and 3 feet and a southeast swell around 1.5 feet through the period. Ilm watches warnings advisories Sc... None. Nc... None. Marine...

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program. |
