(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus62 kilm 220029 afdilm area forecast discussion national weather service wilmington nc 829 pm edt Wed aug 21 2019 Synopsis Isolated showers and thunderstorms, will likely become more numerous in the days ahead, as a front approaches the coast late week, and stalls into the weekend. The increases in clouds and rain chances, should bring cooler daytime temperatures this weekend and early next week. Update No earth-shaking changes made to the forecast, only tweaks to pop values into the overnight period. Near term through Thursday night Low-level water vapor and mosaic radar overlays show outflow intrusion could spark a shower or TSTM from red springs to elizabethtown, particularly as the remnant sea breeze boundary slips beneath the line of convection over central nc dropping ese presently. Outflows could still spark convection near and west of i-95. Guidance continues to indicate another round of shras tstms Thursday aftn, and handled this with a 30% over all inland locations as there's quite a bit of spread as to what areas receive rainfall. No severe weather or flooding anticipated. High temps will range from the upr 80s at the coast to then low mid 90s inland, with heat indices peaking in the 100-104 deg range. Typical nocturnal decrease of precip then into Thursday night, with low temps in the mid 70s. Short term Friday through Saturday night Elongated mid-level ridging over the southern CONUS will be suppressed by 5h trough moving across the great lakes and the northeast late in the week. Bermuda high and piedmont trough tandem will once again lead to diurnal convection fri. However, coverage may actually start to increase Fri night into Sat as a slow moving cold front drops into the area. Front is being pushed south by the 5h trough passing to the north. Shallow nature of the mid-level trough means the front arrives with minimal push and ends up stalling in the region sat. Deep moisture and the stalled front sat and Sat night help ramp up shower and thunderstorm coverage as the week ends. Coverage will decrease somewhat Sat night with the loss of heating, but low level convergence and development of weak wave along the stalled front will keep convection going overnight. Temperatures above to well above climo Fri and Fri night will run closer to climo on Sat due to an increase in both clouds and coverage of convection. Lows Sat night end up a little above climo. Long term Sunday through Wednesday Flat mid level pattern next week keeps the stalled front in the area sun into Mon before high to the north helps push it southeast. Weak surface wave starts to develop over or just off the coast of the southeast Mon into tue. The weak low then drifts northeast, but confidence in its movement is low. Regardless of the location of the low it appears first half of next week will be marked by an extended period of scattered to widespread showers and thunderstorms. -deep moisture, surface boundary, and heating will generate widespread showers and thunderstorms Sun and mon. |
-flooding potential increases Sun and Mon with storm motion under 5 kt and warm cloud layer around 14k ft. -rainfall chances decrease Tue and Wed as the boundary moves farther offshore and mid-level dry air increases. -highs slightly below climo Sun will be near climo mon-wed with lows above climo through wed. Aviation 00z Thursday through Monday PredominantlyVFR this TAF period as typical summertime pattern continues. Outside of a possible stray shower or two this evening, mostly clear skies through tomorrow morning with a few passing high clouds. Scattered cumulus tomorrow afternoon, with chance of summertime thunderstorms later tomorrow afternoon. No fog concerns this TAF period with elevated s-sw winds due to tightened pressure gradient across the area. Winds 5-10 kts overnight, increasing to around 10 kts tomorrow afternoon with enhanced winds at coastal sites with sea breeze. Extended... MainlyVFR thru Fri with brief MVFR ifr periods each day due to aftn evening convection and fog and or stratus around daybreak. A cold front will drop south and stall across the region late Fri thru mon. This will lead to an increase in tsra coverage with MVFR ifr conditions possible at any time of the day or night. Marine Sub-small craft advisory conditions continue this week with bermuda high pressure offshore and a typical piedmont trough inland. Expect s SW winds of 10-15 kt, up to 15-20 kt during the evening hours. Seas 2-3 ft, occasionally up to 4 ft over nc area waters. This will mainly consist of a 4-5 second ssw 2-3 ft wind wave and a 10 second se 1-2 ft swell. Bermuda high will maintain 10 to 15 kt southwest flow Fri into fri night. A cold front arrives early Sat with wind field becoming light and variable Sat into sun. Front pushes a little farther south sun with northeast flow around 10 kt setting up. Northeast flow around 10 kt continues Mon as weak high pressure builds in from the north. Seas around 3 ft Fri drop closer to 2 ft Sat and Sun before northeast flow builds seas closer to 3 ft on mon. Southwest wind wave around 5 seconds weakens Sat Sun as southeast swell around 9 seconds starts to become more noticeable. Northeast wind wave may start to develop on mon, depends how quickly the front pushes south and how strong northeast flow ends up. Ilm watches warnings advisories Sc...

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. |
