868 FXUS62 KMHX 100003 AFDMHX Area Forecast Discussion National Weather Service Newport/Morehead City NC 803 PM EDT Wed Jul 9 2025 .SYNOPSIS... Typical summertime conditions are expected today. This will be followed up by a series of upper level systems that will push across the area bringing unsettled weather through the rest of the work-week. A backdoor front approaches the area this weekend, keeping an active pattern in place. && .NEAR TERM /UNTIL 6 AM THURSDAY MORNING/... As of 8 PM Wednesday... Key Messages - Small potential for strong to severe storms to move into the coastal plain this evening All is quiet across ENC this evening, though a large complex of severe thunderstorms continues over central NC and VA. Almost all model guidance keeps this activity west of the forecast area until it weakens early tonight. However, there is still a small chance that convection makes further eastward progress than anticipated, and this would bring a threat for strong to severe storms to the coastal plain later this evening. Additional shower and thunderstorm activity may move into the area overnight or early tomorrow morning both from the west and south, but with a stable nocturnal environment, the severe threat is looking minimal to none with these storms. && .SHORT TERM /6 AM THURSDAY MORNING THROUGH 6 PM THURSDAY/... As of 215 PM Wednesday... Upper level troughing sets up as the ridge weakens, when paired with a moistening environment, sets the table for increased storm coverage tomorrow afternoon/evening. For this reason, elected to not deviate from NBM with this update. Locally heavy rainfall could result in minor flooding concerns, and gusty, sub-severe winds are possible with the strongest of storms. If the cluster of storms in the morning moves through, it is possible initiation of the afternoon convection is delayed or suppressed with subsidence and/or stable lower levels behind the initial morning convection possible. Increased cloud cover will keep highs a degree or two cooler than today, mid to upper 80s. && .LONG TERM /THURSDAY NIGHT THROUGH WEDNESDAY/... As of 0445 Wednesday...Overall, summertime pattern with SFC thermal trough inland and high anchored offshore. Upper levels have multiple troughs and/or closed lows streaming through Great Lakes and off the NE coast but at our latitude, ridging dominates offshore to the E and over WCONUS. A series of midlevel shortwave troughs will push across the region mid to late week continuing to keep the moisture influx off the Gulf at least somewhat tapped from midlevels downward across SECONUS. Typical diurnal PoP pattern unless a stronger storm cluster persists and drifts into the FA from further inland in the early overnight hours before dissipating. With high PW values, the greatest threat from the storms will be heavy rainfall. WPC currently has at least part of the FA in a marginal ERO for the remainder of the work week. Instability is what you would expect around this time of year, 2-4kJ/kg depending on what guidance you trust. Shear parameters do not look overly impressive given the departure from upper level jet(s) well to the N and offshore high expanding its effective area Ward at the end of the week. With that said, water loading of strongest updrafts could lead to some gustier wind potential should the bottom fall out of more vigorous cells. As such, SPC has parts of the FA in marginal threat for severe storms to develop. Coastal Plain is where the strongest instability and greatest convergence would line up. MaxTs in upper 80s, MinTs mid 70s. This weekend, a backdoor front slowly sags down the MidAtlantic coast but there are tons of model differences in how far and how quickly it will march Sward. This remains contingent on how much momentum gets transferred from the trough aloft exiting NECONUS and where midlevel shortwaves and potential MCSs line up. For now, keeping the backdoor front N of the area until early next week which will keep available moisture for diurnal summer time shower and tstorms in place through the weekend. && .AVIATION /00Z THURSDAY THROUGH MONDAY/... SHORT TERM /through 18z Thursday/... As of 8 PM Wednesday... Key Messages - MVFR conditions possible across the coastal plain early tomorrow morning - Convection likely tomorrow afternoon VFR conditions are present this evening with high pressure offshore. A complex of severe thunderstorms remains off the west over central NC, and has a small likelihood of making to the coastal plain, but will probably dissipate before reaching the forecast area. Ample low level moisture will be present again overnight, and may lead to the formation of low stratus as the boundary layer cools. Best chances at seeing MVFR ceilings will be across the coastal plain from 6z-12z, and there could even be some periods of IFR level stratus before sunrise. Closer to the coast, some transient periods of MVFR are possible, but conditions should remain mostly VFR. VFR conditions will be slow to return tomorrow morning as cloudbases continue to be very low with high amounts of moisture present. Eventually by mid morning, VFR conditions will return everywhere. Scattered showers and thunderstorms are possible tomorrow morning, and will likely become more numerous in the afternoon as a front approaches. LONG TERM /Thursday through Sunday/... As of 0430 Wednesday...A series of mid-level systems will push across the region mid to late week continuing to bring the threat of showers and storms with reduced flight cats. Late night and early morning fog and stratus will also be possible most mornings for areas that see meaningful rainfall. Slow moving front sags down the NE coast late weekend/early week. && .MARINE... SHORT TERM /through Thursday/... As of 8 PM Wednesday..SCAs still in place for coastal waters from Cape Lookout north, as well as the Pamlico, Croatan/Roanoke Sounds as winds remain SW 20-25 kts with gusts to 30 kts here. Winds will peak shortly early this evening, and then slowly subside by early tomorrow morning, with SCAs set to expire at 2 am. Winds tomorrow will be more of the same with SW 15-20 kts in the morning, strengthening to 20-25 kts in the afternoon, with the threat for Small Craft conditions to again develop. LONG TERM /Thursday night through Sunday/... As of 0510 Wednesday...Expect similar to above through the end of the work week, but there may be a SLIGHT downward trend in what the winds will peak at in the afternoons and evenings as the offshore high builds Wward toward the coast FRI. Cold front slowly sags down NEcoast this weekend, but for now, keep it no further S than the NC/VA border until early next week. Therefore, see above. && .MHX WATCHES/WARNINGS/ADVISORIES...
