536 FXUS62 KMHX 030702 AFDMHX Area Forecast Discussion National Weather Service Newport/Morehead City NC 302 AM EDT Thu Jul 3 2025 .SYNOPSIS... Cloudy and foggy start to the day will give way to more typical scattered showers and thunderstorms as frontal boundary stalls over the area. High pressure builds in from the west through the holiday weekend with the frontal boundary stalling off the Southeast coast. && .NEAR TERM /THROUGH TODAY/... As of 300 AM Thurs... Key messages: - Risk of low stratus and fog to start Thursday morning. - Lower coverage of showers and storms this afternoon and evening, although risk of iso flash flooding remains. Latest analysis shows broad troughing persisting over the mid- Atlantic and northeastern CONUS, with a second weaker trough sitting over the southeast. At the surface, frontal boundary is stalled over the Piedmont of NC, leaving eastern NC in weak southerly but warm and muggy flow. This airmass is proving favorable for low stratus and fog development, especially along the I-95 corridor. Expecting this bank to expand southward through the morning, building in behind iso to sct shower activity developing along an offshore trough. Aforementioned precipitation is most likely east of Highway 17 and the Outer banks, although it is not expected to be nearly as torrential as yesterday`s storms. Front is forecast to edge eastward through the day, eventually stalling over ENC in the afternoon. By this time, more drier air will be working in aloft and forcing will be considerably weaker which should limit overall coverage compared to yesterday. However, with PWATs still between 1.50-2" and very slow forecast storm motions, periods of heavy rainfall are still in the cards with a risk of isolated flash flooding. Most favored area for convection is along and slightly north of the Highway 24 corridor, along the slow moving sea breeze, with additional development likely upstream along the stalled and diffuse frontal boundary. Highs reach to near 90 inland, mid to upper 80s OBX. && .SHORT TERM /TONIGHT/... As of 300 AM Thur...Typical summertime evening for ENC as afternoon convection gradually disperses, giving way to mostly clear skies and lows falling into the low to mid 70s. Winds once again remain light as front remains stalled over the region, and with very moist soils conditions remain favorable for some fog development in the early morning hours. A few spotty showers may graze the Outer Banks as activity blossoms over the Gulf Stream Fri morning. && .LONG TERM /FRIDAY THROUGH WEDNESDAY/... As of 1:30 AM Thursday... Key Messages - High pressure builds in late week, bringing back the typical summertime pattern with sea breeze convection - Tropical or subtropical development is possible this weekend/early next week off the southeast coast A mid-level shortwave rounding the base of a closed low over southern Quebec will push a weak reinforcing cold front south into our CWA early Friday. This feature doesn`t look to bring much more than a wind shift to the north with the focus of afternoon shower and thunderstorm chances being along the sea breeze. The weekend will host our typical summertime pattern with daily seabreeze convection and highs in the upper-80s. The front that will stall across the area today will eventually stall off the southeast coast this weekend. A low pressure system is then forecast to develop along this boundary near Florida or the southeast coast by early this weekend. NHC is giving this disturbance a 50% chance of becoming a tropical or subtropical depression with guidance showing north or northeastward movement thereafter. A lot of uncertainty remains, but regardless of where this system ultimately moves, higher than normal daily rain chances can be expected through mid-week. && .AVIATION /06Z THURSDAY THROUGH MONDAY/... SHORT TERM /through 06z Fri/... As of 300 AM Thurs...Mixed bag of flight conditions this morning across ENC terminals as slow moving cold front sits over the NC Piedmont. Bank of fog and low stratus has already quickly developed to our north and west, stretching from KORF southwestward to KJNX. MVFR is predominant in our region with spotty convection over the waters occasionally bleeding inland. Forecast calls for low stratus deck to gradually expand southward through the morning as aforementioned shower activity shifts further offshore, although LAMP guidance seems to be more aggressive than observations. PGV and ISO remain the most likely to see IFR cigs and fog, but EWN and OAJ are likely to see restrictions closer to dawn. With light winds today and poor mixing, cigs will be slower to lift than usual. Still, VFR is likely to prevail by midday with a renewed risk of showers and thunderstorms focused along the seabreeze, with activity gradually expanding northward. EWN and OAJ have the highest chance of experiencing convective impacts. Precipitation quickly dies off after sunset. LONG TERM /Friday through Monday/... As of 2 AM Thursday...Predominantly VFR conditions are expected through the period outside of afternoon shower and thunderstorm chances. There`s potential for a tropical or subtropical depression to develop off the southeast coast this weekend or early next week which will increase chances for sub-VFR flight conditions into early next week. && .MARINE... SHORT TERM /through Thursday/... As of 300 AM Thurs... Key Messages - Shower and thunderstorm activity continues over area waters through this morning Regional observations show southwesterly winds of 10-15 kt continuing over area waters this morning as cold front remains across western NC, with seas around 3-5 feet. Overnight convection coverage is quite robust, impacting all marine zones, and will remain a concern for boaters through the morning hours before waning late morning. Frontal boundary will stall over ENC later this afternoon, resulting in variable but generally light winds of 10 kt or less through Thurs PM. Front will finally push offshore on Fri morning with more widespread northerly winds expected to prevail by the end of the short term. With light winds, seas fall further to around 2-3 feet. LONG TERM /Friday through Monday/... As of 2:10 AM Thursday...Sub- SCA conditions are expected through the period. 10-15 kt winds will veer to the northeast Friday morning and remain status quo until Saturday afternoon when they become more easterly. Winds will continue to veer to the southeast on Sunday and then to the south on Monday. Seas will generally be 2-4 ft on Friday, increase to 2-5 ft this weekend south of Cape Hatteras, and then return to 2-4 ft to start the new week. && .MHX WATCHES/WARNINGS/ADVISORIES... NC...None.
