520 FXUS62 KMHX 071953 AFDMHX Area Forecast Discussion National Weather Service Newport/Morehead City NC 353 PM EDT Mon Jul 7 2025 .SYNOPSIS... A series of mid level systems will push across the area bringing periods of unsettled weather through the rest of the week. && .NEAR TERM /THROUGH TONIGHT/... As of 3 PM Monday...The remnants of Chantal is pushing across the Delmarva Peninsula this afternoon while high pressure centered across the western Atlantic is ridging into the southeast. Broad subsidence aloft has prevailed across ENC so far this afternoon keeping showers rather isolated and short- lived despite moderate instability. Best chance for precip continues to be north of the Pamlico River this afternoon with chances quickly diminishing early this evening with loss of sfc heating and dry conditions expected through the rest of the overnight. Warm and muggy temps overnight with lows in the mid to upper 70s. && .SHORT TERM /TUESDAY/... As of 3 PM Monday... Key Messages - Hot with heat index values peaking up to 106 degrees - A marginal chance for severe storms across the coastal plain in the afternoon. High pressure continues off the coast Tuesday while a mid-level shortwave pushing into the Ohio River Valley with thermal troughing across the piedmont. Isolated to widely scattered showers and thunderstorms expected to develop along the sea breeze as well as the inland thermal trough which will propagate toward our area through the afternoon. Strong sfc heating will bring moderate instability with SBCAPE peaking around 2500-3000 J/Kg and could see some more robust storms producing strong winds gusts despite meager shear of 15 kt or less and SPC has the western coastal plain in a marginal risk for severe storms Tuesday. Hot and humid conditions will persist with temps a couple of degrees warmer, in the mid 90s inland and upper 80s/lower 90s along the coast. With dew points in the mid 70s, heat index values are expected to peak around 103-106 degrees and have issued a Heat Advisory for all but the coastal zones. && .LONG TERM /TUESDAY NIGHT THROUGH MONDAY/... As of 3 PM Monday...A similar set up to Tuesday afternoon is expected for Wednesday, with a similar threat of strong to severe storms exists over the coastal plain. ~2000 J/kg MLCAPE coupled with meager bulk shear will limit the overall severe threat. SPC has the far western portions of the CWA in a marginal risk, mainly for the potential for isolated damaging wind gusts. Elevated PWATs will continue to support a risk for heavy rainfall and isolated flooding, with WPC having a marginal ERO for the western forecast area on Wednesday. With increasing thicknesses due to the building ridge, the warm temps expected Tuesday are forecast to continue into Wednesday with MaxTs in the low 90s inland from the coast and peak heat index values around 100-105. A series of shortwave troughs will push across the region mid to late week continuing to bring an unsettled pattern across the region. With high PW values, the greatest threat from the storms will be heavy rainfall. WPC currently has marginal EROs for Days 3-5 for at least portions of the forecast area. At this time, instability and shear parameters do not look overly impressive for severe storms to develop but could see a few storms producing strong wind gusts. Temps expected to be near or a couple of degrees below climo. && .AVIATION /19Z MONDAY THROUGH SATURDAY/... SHORT TERM /through Tuesday/... As of 330 PM Monday... Key Messages - VFR conditions will prevail outside of widely scattered thunderstorms Upper ridging over the area in the wake of Chantal is bringing broad subsidence across the region helping to limit convection this afternoon but cannot rule out an isolated thunderstorm bringing brief sub-VFR conditions at the terminals. Expect VFR to continue overnight with potential for fog less than 10%. A mid-level shortwave approaches from the west on Tuesday bringing somewhat better chances for showers and thunderstorms during the afternoon. A few storms could produce strong wind gusts, with best chance late afternoon at western TAF sites. LONG TERM /Tuesday night through Friday/... As of 3 PM Monday...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. && .MARINE... SHORT TERM /through Tuesday/... As of 330 PM Monday...Current obs showing S to SW winds around 10-20 kt across the waters with gusts to around 25 kt across the Pamlico Sound and waters north of Oregon Inlet, and seas around 3-5 ft. Conditions will continue to improve through the overnight with winds diminishing to 10-15 kt late tonight. Expect to see a tightening pressure gradient tomorrow between the inland thermal trough and offshore high pressure with daytime heating bringing winds back to around 10-20 kt. Seas will subside to 2-4 ft tonight and continue through tomorrow. Will continue the SCA for the Pamlico Sound and waters north of Ocracoke through 00z Tuesday as frequent gusts to 25 kt persist but may be able to be lowers sooner as conditions warrant. LONG TERM /Tuesday night through Friday/... As of 3 PM Monday...High pressure remains centered over the Wern Atlantic this week with a series of systems pushing across the area. This will keep gradients somewhat pinched with SW winds around 10-20 kt (occasionally higher gusts possible), highest in the late afternoon and evening with thermal gradient peaking. Seas generally around 3-4 ft during the long term period, however the dominant period through at least midweek will be on the shorter wind wave side, 5-6sec. So, expect bumpy 3-4ft wind waves out of the S/SW on top of 1-2ft long period swell on the order of 13-15sec out of the east. && .MHX WATCHES/WARNINGS/ADVISORIES...
