449 FXUS62 KMHX 011738 AFDMHX Area Forecast Discussion National Weather Service Newport/Morehead City NC 138 PM EDT Mon Jul 1 2024 .SYNOPSIS... Cold front will move through the area this morning with high pressure building back into the area from the north on Tuesday. Oppressive heat and humidity build back in over the second half of next week. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... As of 115 PM Mon...Front has now pushed offshore with just some scattered showers remaining over land and most of the heavy rain offshore. High res guidance has poorly handled the anomalously cool airmass coming in behind the front, and have had to lower temps and dewpoints for the rest of today. Temps will rebound into the mid to upper 70s this afternoon as the clearing line heads east, with only a few of the sunnier spots touching 80. && .SHORT TERM /6 PM THIS EVENING THROUGH 6 AM TUESDAY/... As of 400 AM Mon...High pressure and drier airmass will settle over eastern NC tonight with skies continuing to clear, although some clouds likely linger south of Highway 70. With freshly saturated soils and light winds cannot rule out a ground fog threat early Tues morning. Lows will reach unseasonably cool levels, dipping into the low 60s inland while along the immediate coast upper 60s to low 70s will hold strong. && .LONG TERM /TUESDAY THROUGH MONDAY/... As of 135 PM Mon... KEY MESSAGES: - Cooler than average temps are forecast on Wed - Oppressive heat and humidity return this weekend Wed...Upper troughing will be located offshore at the start of the period and continue to push E`wards further into the Atlantic while upper ridging continues to build over the Southeast Wed. At the surface, high pressure gradually slides E`wards into the Atlantic on Wed turning winds to the E and then SE by Wed afternoon as fair weather continues across the area. Highs get into the 80s with lows in the the 60s to low 70s. With dewpoints forecast to be in the 60s, it will feel much more comfortable outside through midweek. Thurs through the weekend... Our most impactful weather likely occurs at the end of the week and into the weekend as oppressive heat and humidity sets up across the Southeast once again. Upper ridging will remain overhead into next weekend as any upper level troughs struggle to dig S`wards. At the surface, high pressure ridging will continue to push further offshore through the end of the week allowing return flow and moisture return to resume across ENC. As mentioned above, temps will steadily warm into the weekend allowing oppressive heat and humidity to return to ENC starting on Fri and persisting into the end of the weekend. Otherwise climatological avg precip chances will resume starting this weekend as well with at least a chance for some shower and tstm development each afternoon along the seabreeze. && .AVIATION /18Z MONDAY THROUGH SATURDAY/... SHORT TERM /through 18Z Tue/... As of 135 PM Mon...Key messages: VFR conditions will develop by evening and gusty winds will diminish early this evening. Occasional MVFR ceilings and NE winds gusting to 20 kt will prevail at the TAF sites until late today. High pressure will build south over eastern NC tonight and Tuesday resulting in VFR conditions and light winds developing early this evening and continuing Tuesday. Overnight there will be enough low level mixing to preclude fog while the low levels are forecast to be too dry to support low stratus cloud formation despite easterly flow. Southwesterly winds this morning quickly veer northerly and then northeasterly behind the front, gusting to 15-20 kt through the afternoon. LONG TERM /Tue night through Saturday/... As of 315 PM Mon... Primarily VFR conditions forecast through the period with light winds as high pressure settles in across the Eastern Seaboard. && .MARINE... SHORT TERM /Through Tonight/... As of 410 AM Mon...Regional observations show south to southwesterly pre-frontal flow prevailing across area waters, reaching 10-15 kt with gusts nearing 25 kt at times. The front, currently over the VA/NC border, will continue to drop southward through midday with models still insistent on a north to northeasterly surge of around 20 kt with higher gusts. Latest trends show a stronger signal for gustier conditions over the Albemarle Sound and Alligator River, and extended SCA headlines to capture these waters during the morning and early afternoon. The brevity and marginal nature of the winds will keep seas below 6 feet through the period. Shower and thunderstorm threat associated with the front will continue across all waters into midday, ending from north to south. Shower threat will continue into the mid afternoon south of Cape Lookout. LONG TERM /Monday Night through Friday/... As of 315 AM Mon...Mostly benign boating conditions are forecast for the period. Initially, high pressure ridging will settle in across the Eastern Seaboard as a frontal boundary remains to the south of the area. This will keep a tighter pressure gradient over our waters at the start of Tues allowing for NE`rly winds at 15-20 kts and 3-5 ft seas to persist into Tues evening. Occasional 6 ft seas are possible mainly along the Gulf Stream waters but think any chance at 6 ft seas quickly end by mid morning. Then as high pressure ridging continues to gradually push E`wards across the area, the gradient will relax allowing winds to ease to 5-10 kts while becoming more E`rly by Wed morning. Winds continue to remain light and veer to the SE and eventually the S on Thurs as ridging becomes centered to the E. Seas will gradually lower as well Wed and Thurs down to 2-4 ft. && .MHX WATCHES/WARNINGS/ADVISORIES... NC...Beach Hazards Statement until 8 PM EDT this evening for NCZ203.
