(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus62 kilm 171535 afdilm area forecast discussion national weather service wilmington nc 1135 am edt Sat aug 17 2019 Synopsis Unsettled weather will last into the weekend as a stalled front weakens along the coast. A slight drying trend on Monday will give way to an active weather pattern with scattered showers and thunderstorms each day next week while temperatures remain near normal. Update (9:01 am edt) rest of today Latest model soundings have atmospheric precipitable water around 2.4 inches, which is very close to the daily MAX based on climatology from charleston, sc observed sounding analysis. Wilmington airport (ilm) set a daily precipitation record yesterday at 3.04 inches, and the synoptic setup with the stationary frontal boundary has not changed from 24 hours ago. All that said, the main update this morning to the forecast is to add the mention the locally heavy rainfall likelihood today. Heavy rainfall could result in localized minor flooding and ponding of water across poor drainage and low lying areas. Near term through Sunday Latest sfc analysis shows a stalled frontal boundary just west of the fa and a very disorganized sfc pressure pattern. Not much change in the pattern today from yesterday... With transient shortwave energy aloft in conjunction with high low mid-level moisture profiles leading to periods of moderate to heavy rain. Best chance again is near the coast as shortwaves pass along and just off the coast. Maintained mention of localized minor flooding and ponding of water in the hazardous weather outlook. Thunderstorms also likely but severe weather is not expected. Looks to be a gradient in high temps today... Highs only in the low mid 80s east due to more precip and cloud cover, up to the upr 80s far western areas. The rain shifts offshore tonight, with chances for patchy fog increasing inland. Low temps in the low mid 70s. Best moisture axis shifts offshore into Sunday, but with the weak frontal boundary still in the vicinity have chance pops (30-50%) through the day. QPF amounts will be lower than those of today. High temps in the upr 80s to lwr 90s most areas. Short term Sunday night through Monday night Deeper moisture seemingly has to give way to dry air as seen on water vapor imagery this morning to both the east and west. Guidance appears to show this although not to the extent currently. This will keep pops a bit lower Sunday night but daytime heating and the mixing warrants good chance pops Monday. Temperatures will be very similar to past days with highs in the upper 80s and lower to middle 90s with lows well into the |
70s. The highs will be highly dependent on the extend of the moisture. Long term Tuesday through Friday Deep moisture remains in place for the most part with intervals of drier air perhaps. There will seemingly be periods of lower pops but extended panels differ on timing. Long story short some semblance of pops are in the entire forecast. More amplitude toward the end of the period along with an approaching front increase the forcing with the moisture. Really no change in the temperature forecast. Aviation 18z Saturday through Thursday As of 18z... Deep moisture in place with convection expected through much of the forecast period. Brief periods of low visibilities in the heavy rain, but lasting less than ten minutes for the most part. Tonight, a tropical low tracks up the coast, with increasing chances for heavy rain. Ceilings and visibilities will be ifr in many areas. The low will track northward and winds will swing around to northwest on the backside of the low. This will probably shut off the precip at last. Extended... An active summer period with increased moisture and the threat for MVFR ifr conditions from afternoon and evening thunderstorms each day. Morning low stratus and fog will produce MVFR ifr conditions this weekend into next week. Marine A stationary frontal boundary remains inland today with SW flow over the waters. Expect mainly 10-20 kt sustained winds, with gusts up to 25 kt. With guidance trending up both in terms of winds and seas, have gone ahead and hoisted a small craft advisory through tonight. Winds diminish a bit to only 10-15 kt Sunday. Seas 3-5 ft this weekend, with a few 6 footers out 20 nm possible. Expect a wave direction out of the south, 6-7 second period. Summer or late summertime pattern remains unchecked through the work week. This means southeast to southwest winds of 10-15 knots for the most part. An approaching front late in the period may increase speeds and has the outside chance of leasing to a synoptic wind shift but guidance remains mixed. Significant seas will be the standard 2-4 feet.
