Area Forecast Discussion National Weather Service Newport/Morehead City NC 724 AM EDT Wed Apr 8 2020

SYNOPSIS. A series of weak disturbances will move across the area into Thursday with a mainly dry cold front pushing through the area late Thursday. Cooler high pressure fills in late in the week before a stronger frontal system impacts the region Sunday into early next week.

NEAR TERM /UNTIL 6 PM THIS EVENING/. As of 710 AM Wednesday . Skies are clear across the CWA at daybreak with temperatures in the mid 60s. Leading edge of convective complex is weakening west of the Richmond, VA area and should dissipate before reaching our area. With subsidence ahead of the oncoming front today, expect generally sunny skies. Coupled with the SW wind flow, temperatures should warm well into the 80s away from the coast, as thickness values support some mid/upper 80s inland this afternoon. The convective complex is likely to refire later in the afternoon over our far northern tier and move south toward the coast during the evening hours, but for the bulk of the MHX CWA, dry conditions are expected through at least late afternoon.

SHORT TERM /6 PM THIS EVENING THROUGH 6 AM THURSDAY/. As of 355 AM Wednesday . With temperatures pushing well into the 80s, especially inland, CAPE values as high as 1500 J/kg will characterize the pre-storm environment ahead of convective complex associated with a surface trough diving south into the region by early evening. Almost all of the high-resolution models produce a broken line of convection in the evening, gradually ending by midnight or so. Biggest question is coverage of convection and have kept PoPs in the 20-30 percent range for the evening, with the higher values over the northern tier. A few strong wind gusts and hail may accompany the stronger storms and SPC has the entire CWA in the Marginal Threat zone. Once precipitation ends after midnight, lows will drop into mainly the lower 60s with leftover convective debris clouds likely.

LONG TERM /THURSDAY THROUGH TUESDAY/. As of 330 AM Wed . A few showers and thunderstorms are possible Thursday ahead of a cold front that will cross the area later in the day. Drier and cooler conditions are then on tap for Friday into Saturday. The next storm system will impact the area Sunday into Monday with high pressure returning thereafter.

Thursday through Saturday . What remains of a convective line that will move across central VA Wednesday night could reach NE NC Thursday morning, prompting a few showers and thunderstorms to develop within the modest band of pre-frontal moisture convergence over the area. Though the best forcing is expected before peak heating, 1000+ J/kg could still be in place, and a few of the storms could become strong to severe, with damaging wind gusts and hail possible. Drying occurs immediately ahead of the cold front, which will cross the area with little fanfare beyond a wind shift through the later afternoon and early evening. Low level thickness values support highs returning into the mid to upper 80s, with a few locations reaching 90 not out of the question, ahead of the front Thursday afternoon.

High pressure building into the area behind the front will keep dry conditions in place Friday and Saturday, with temps below normal both days. Efficient radiational cooling is expected Friday night, with lows dipping into the 30s, and the potential for frost away from the beaches Saturday morning.

Sunday through Monday . Longer range guidance continues to converge on the solution of a potent H5 shortwave lifting from the south central US across the Midwest Sunday, with the associated complex surface low crossing the Tennessee Valley and riding up the Appalachian Mountains through Monday. This will likely result in a warm front crossing the area Sunday, with strong WAA on the back of a 50+ kt LLJ Sunday night into Monday. Given this wind profile and the potential for instability to quickly build, severe weather is a concern Sunday into Monday, as are strong gradient winds, especially along the coast. Details of the severe threat will be refined in the coming days, but currently carrying the threat for thunderstorms Sunday through Monday in the official forecast.

Current expectation is that a cold front will move through Monday, with generally dry conditions behind it for Tuesday. However, upper level heights could continue to fall, and dry conditions are not a guarantee Monday night into Tuesday as broad lift could occur across the region. Regardless, much cooler temps are expected Tuesday through the middle of next week.

AVIATION /11Z WEDNESDAY THROUGH SUNDAY/. Short Term /through 12Z Thursday/ . As of 710 AM Wednesday . Skies are clear across the region at daybreak and should remain that way into the afternoon, although some cirrus blowoff from convective system in Virginia may effect areas near the Virginia border this morning. The convective complex may refire during the late afternoon and early evening and move south and impact the TAF sites, mainly between 00z and 03z or so. Still too much question in terms of any convective coverage to include in TAFs at this time, and will simply indicate scattered cumulus clouds in the 50-80 foot range.

Long Term /Thursday through Sunday/ . As of 330 AM Wed . VFR prevails through Saturday. A prolonged period of flight restrictions and LLWS is possible beginning Sunday as a strong frontal system impacts the area.

MARINE. Short Term /through Tonight/ . As of 715 AM Wednesday . W/SW winds currently on the coastal waters, with gusts to 27 knots at Diamond Buoy, 25 knots at the buoy 30 miles south of New River Inlet, but mostly 15 knots or less elsewhere. Seas are in the 3-6 foot range. SW winds will remain gusty today into this evening, before subsiding in the wake of surface trough with scattered convection later this evening and overnight. However, seas will remain rough and SCA's continue in effect on the coastal waters south of Oregon Inlet until 2 AM Thursday.

Long Term /Thursday through Sunday/ . As of 330 AM Wed . Breezy southwesterly flow prevails through Thursday afternoon ahead of a cold front that will cross the waters Thursday evening. Winds shift abruptly to breezy NW behind the cold front, then gradually wane into Friday as cooler high pressure builds in. A strong frontal system will impact the area beginning Sunday, bringing the potential stronger winds.

Seas of 4-6 ft prevail Thursday in mainly southerly windswell, with seas subsiding gradually Thursday night into Saturday as the windswell fades. Seas increase quickly beginning later Sunday as the next strong frontal system begins to impact the area.

TIDES/COASTAL FLOODING. As of 3 AM Wed . A perigean spring tide will bring elevated tidal levels today through the end of the week. Minor inundation of very low lying areas is possible around the times of primarily the evening high tide cycles, especially near inlets and along the beaches south of Cape Lookout Tuesday, then across all of eastern NC Wednesday into late week.

MHX WATCHES/WARNINGS/ADVISORIES. NC . None. MARINE . Small Craft Advisory until 2 AM EDT Thursday for AMZ152-154- 156-158.

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.
