226 FXUS62 KMHX 180151 AFDMHX Area Forecast Discussion National Weather Service Newport/Morehead City NC 951 PM EDT Mon Jun 17 2024 .SYNOPSIS... High pressure dominates through Thursday resulting in dry and warm conditions. Coastal troughing may bring some showers to the region late in the week into the weekend. && .NEAR TERM /OVERNIGHT/... As of 950 PM Mon...Mid-level ridge remains centered overhead, while at the surface high pressure centered off the coast of New England extends into the southeastern CONUS. Sea breeze circulations are dominant along the coast but strong subsidence from the aforementioned ridge is shutting the door on any convective development. Little change in the overall pattern for tonight, with no significant changes needed to previous forecast for update. Skies will clear overnight and light to calm winds inland will lead to a favorable radiational cooling setup. Min Tds this afternoon reached well into the low 60s and nudged forecast lows close to this benchmark. Retained upper 60s to low 70s along the coast where winds will likely remain elevated and keep low- levels mixed. Overall column looks to be too dry to support a mentionable fog threat, although very patchy ditch fog cannot be ruled out. && .SHORT TERM /TUESDAY/... As of 310 PM Mon...Pattern of warm but dry conditions carries into tomorrow as core of the upper high shifts northward. This will keep the most intense heat displaced from our area, but warm conditions will once again prevail. Highs range tomorrow from the low 90s inland to mid 80s along the coast. Predominantly easterly winds in the morning will give way to dominant sea and sound breeze circulations in the afternoon. Still relatively dry for mid to late June as Tds drop into the upper 50s, resulting in RHs in the 35-40% range across the inner coastal plain. This will pose a continued fire weather risk...see the FIRE WEATHER section for more. && .LONG TERM /TUESDAY NIGHT THROUGH MONDAY/... As of 3 AM Mon...Pleasant but dry weather through mid week, then heat and humidity build at the end of the week through the weekend. Small chances for showers and perhaps a few storms Friday into the weekend. Tuesday through Thursday...Strong ridging will build over the eastern US through mid- week, which will bring cont rain- free weather. The core of the ridging will remain north of ENC initially, and thus keeping the intense heat to the north across the Mid Atlantic, Great Lakes, and Northeast. For ENC, easterly flow is expected, which will keep conditions tempered, and in fact quite pleasant. Highs expected in the mid-upr 80s interior, to low 80s OBX. In addition, TD`s will be very tolerable, and remain in the 60s. This will bring cool nights to the region, with lows in the 60s away from the immediate coast, to low 70s beaches and OBX zones. Friday through the Weekend...There are still notable differences in the long range models, but the consensus is that weak low pres will develop east of the Bahamas and move west towards the Southeast Coast (FL/GA). Center of upr ridge will slide eastward a bit with a weakness allowing for some weak mid level troughing, and allowing for more of a serly to srly flow to develop and bring inc heat and humidity starting late this work week into the weekend. PoPs remain low, though by Fri into the weekend, some chance of a return to typical afternoon/early evening sea breeze convection. Pops remain at only 20-30%, as no strong forcing feature is noted on med range ensembles. Temps will be on the rise, into the 90s Fri into the weekend. TD`s will rise steadily as well, and a potential for heat indices into the upr 90s to low 100s. && .AVIATION /02Z TUESDAY THROUGH SATURDAY/... SHORT TERM /through Tue/... As of 630 PM Mon...Pred VFR conditions through the period with sprawling high pressure off the mid- Atlantic coast in control. Few to sct cu field this afternoon will be short lived, giving way to clear skies and nearly calm winds overnight. Column appears too dry to support fog formation and kept this out of the TAFs, but some offshore strato-cu could drift onshore overnight, bringing potential MVFR cigs to primarily OBX locations. Similar set up Tue, with potential for mainly diurnal sct cu and light to moderate easterly winds. LONG TERM /Tuesday night through Saturday/... As of 3 AM Mon...VFR conditions expected through the period with high pressure remaining dominant through the period. && .MARINE... SHORT TERM /through Tuesday/... As of 950 PM Mon...Benign boating conditions expected to continue through tomorrow as high pressure remains in control over the waters. Latest obs show E-SE winds 5-15 kt with seas 2-4 ft. Little change overnight with winds a couple knots stronger tomorrow, which may encourage more widespread 4 foot seas across area waters. Still, marine headlines are not expected through the short term period. LONG TERM /Tuesday night through Saturday/... As of 3 AM Mon...Sub- SCA through the period with high pressure anchored to the north of ENC. Light to moderate erly flow of 10-15 kt, ocnl gusts to 20 kt expected. Seas will generally be 2-4 ft through mid week. Low pres will develop east of the Bahamas this week and approach the SE Coast (FL/GA) by mid week. Some higher swell may approach and seas possibly exceeding 6 ft Wed night into Thu for the ctrl/srn waters. && .FIRE WEATHER... As of 310 PM Mon...A dry airmass will be in place through mid week, with minimum RH in the 30s and 40s percent, especially away from the coast. This will overlap with breezy E winds at times, and is noteworthy for any ongoing, or planned, fires. && .MHX WATCHES/WARNINGS/ADVISORIES... NC...None. MARINE...None. && $$ SYNOPSIS...MHX NEAR TERM...CQD/MS SHORT TERM...MS LONG TERM...SK/TL AVIATION...CQD/TL/MS MARINE...CQD/TL/MS FIRE WEATHER...MHX
