(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus62 kilm 180136 afdilm area forecast discussion national weather service wilmington nc 836 pm est Sun feb 17 2019 Synopsis Damp conditions can be expected overnight as a warm front lifts to the north, accompanied by areas of fog and mist. A cold front will stall south of the area late Monday, and meander across the carolinas much of the upcoming week, leading to periods of light and moderate rain in the week ahead. High pressure may bring a dry day this Tuesday. Near term through Monday night As of 836 pm Sunday... Forecast rain chances and mosaic radar trends remain in good sync presently and no major changes were needed. Expect atypical temperatures overnight, rising through the night, 10 deg f or better in spots, as a warm front lifts across the area. The warm front was positioned across southern sc to central ga this mid-evening, migrating north. Although rain chances will trend higher overnight, overall amounts in the rain buckets to remain minimal. Patchy fog to plague inland sites, and also the coast into early Monday, as ascending dewpoints traverse cooler inshore waters. As of 609 pm Sunday... No significant adjustments were needed, only change was to bring patchy fog across the coastal zones as the potential for sea fog increases into early Monday, as dewpoints rise in an onshore flow over the chilled ssts. As of 3 pm Sunday... Ample cloud cover in place as south-southwest low-level flow overspreads a very shallow ridge in place across the carolinas. The ridge will lose its influence this evening allowing a warm front to move across the area. Low temperatures tonight will occur early as temperatures rise overnight. Best rainfall chances will occur farther inland and QPF will be limited, generally less than a tenth inch most locations tonight into Monday, before some clearing occurs and isentropic glide becomes neutral. A cold front will shift off the coast Monday afternoon, but cold air is lacking with FROPA and highs Monday will be well above normal. This thinking is in line with the favored warmer ece mav highs for Monday. Ridge building in from the oh valley Monday night will allow lows to drop into the upper 30s northern and western areas to the lower 40s at the coast and southern zones. Short term Tuesday through Wednesday night As of 330 pm Sunday... The 1st half of Tue will remain primarily dry but unfortunately an increase in overrunning type cloudiness as a wedge sets up. Ridging with cold air funneling southward will dominate tue. Models have backed off on the pops for daytime Tue but will continue to carry a low chance especially further inland. By and during wed, the source of the cold air, ie. The center of the high, is progged to move off new england. Thus expect a partial breakdown of this wedge which will allow the inverted sfc trof or coastal front, to push onshore and inland. This is where the potential for a temp fcst bust will be at it's hiest. How far inland this trof front goes will also be a focus for precip with stratiform type pcpn north of this boundary and the more convective ie. Showery in nature, south of this boundary. Pcpn amounts for this short term period will generally run one tenth to one-quarter of an inch near the coast and one quarter to one half inch inland. Long term Thursday through Sunday As of 330 pm Sunday... The longwave pattern this period will remain relatively unchanged with a sfc frontal boundary running sw to NE from the NW gulf of mexico northeast to off the mid- atlantic states coast. The longwave pattern aloft will also remain relatively unchanged with the center of the upper high over the bahamas and a somewhat amplified upper trof across the western u.S. This scenario keeps an open moisture feed from the gulf of mexico across the fa. In addition, weak vorts rotating around the base of the amplified western u.S. Upper trof, will track NE and pass and remain far enough inland from the ilm cwa from any direct influence. Nevertheless, isentropic lift ie. Overrunning, will dominate the production of clouds and stratiform type pcpn for the ilm cwa. Models indicate Thu will be the "driest" day of the long term period. And in addition, the mildest or warmest, depending if temps make it into the 60s or 70s. Models indicate a possible breakdown of this longwave pattern that could put an end to this wet regime. But given 7 |
days out, will not jump on the band wagon as of yet but will back down on the pops and decrease the cloudiness some. Aviation 02z Monday through Friday As of 0z... .Sub-vfr conditions across the area, with ifr lifr and less than 5mi vsby inland and MVFR along the coast. Look for conditions to remain sub-vfr through tomorrow afternoon, before a cold front pushes through the area around 18z and lifts the low level cloud deck. At inland terminals, look for ifr ceilings to persist though tomorrow morning, possibly lifr at times, with MVFR fog likely early morning. Ifr should lift to MVFR in the morning before clearing toVFR around 17z. Llws also briefly forecasted between 6 and 8z at flo and lbt when a 40kt jet develops around 2 kft. Coastal terminals will be a little trickier. Currently MVFR, on the border of ifr. Most likely will be repeat of last night where coastal sites oscillate between the two categories. Have forecasted a decline into ifr overnight as a warm front makes its way into the area, and then improving to low MVFR in the morning, before clearing toVFR around 18 19z. Potential for sea fog overnight, especially at the myrtles, and so have included decreased visibilities to account for this. Best rain chances will be inland overnight, but will remain light and scattered and so have just included vcsh at flo and lbt. Extended outlook...VFR likely Tuesday. Unsettled weather Wednesday through Friday with MVFR ifr lifr conditions possible at times. Marine Tonight thru Monday night as of 609 pm Sunday... Ese waves every 10-11 seconds and shorter period E wind-seas prevailed, mixed with s-sse waves every 5-6 seconds. As a warm front lifts north overnight, mist and fog could reduce visibility after midnight, through daybreak Monday. No tstms, but drizzle and occasional light rain will keep marine conditions damp. No significant changes this update. As of 3 pm Sunday... The surface ridge currently across the carolinas will weaken as the old front lifts northward. The flow will veer around from the current northeasterly direction to the south- southwest overnight. The flow will increase as well, likely to just below small craft thresholds by daybreak Monday. By Monday afternoon winds will veer to an offshore direction as a cold front begins to push offshore. The pressure gradient behind the cold front is weak initially and light northerly flow is expected by Monday evening. However a surge will increase north- northeast winds across the waters Monday night with an increased potential for small craft conditions developing. Seas of 3-5 ft are likely late tonight into Monday morning, before subsiding Monday afternoon and early evening. Seas will increase again with the aforementioned surge arriving Monday night. Tuesday thru Friday... Tuesday will be highlighted by a wedge setting up shop across the carolinas with an inverted sfc trof or coastal front taking shape just offshore and parallel to the coastline. The sfc pg will tighten to the point where winds will surpass sca thresholds and in turn, significant seas will also build to and above SCA thresholds. Northeast to east wind waves will dominate the sig. Seas with 4 to 6 second periods common. East of the coastal trof, SE to S winds will be busy and add to the mix especially when the coastal trof front gets pulled onshore by wed. The sfc pg will continue to remain tightened with winds 15 to 25 kt with few gusts up to 30 kt especially east of the coastal front. Winds and seas will finally abate and subside- some Thu into Fri due to a brief lull in the passage of mid- level S W trofs or vorts. The frontal boundary may drop back southward during Friday and could result in winds backing to the ne with seas remaining in the 3 to 5 ft range. Ilm watches warnings advisories Sc... None. Nc...
