000 FXUS62 KMHX 231403 AFDMHX Area Forecast Discussion National Weather Service Newport/Morehead City NC 1003 AM EDT Tue Apr 23 2024 .SYNOPSIS... High pressure briefly builds into the area from the south through tonight followed by a frontal passage with limited moisture on Wednesday. High pressure builds back into the area from the north for the latter half of the week. && .NEAR TERM /TODAY/...
-- Changed Discussion --
As of 10 AM Tuesday... No significant changes to the forecast this morning as high pressure ridging continues to extend N`wards into ENC this morning with clear skies and steadily warming temps across the region. Prev Disc...High pressure will build across the area today with the ridge axis moving offshore this afternoon. This is notable because this will cause the cold northerly flow currently occurring across eastern NC to shift to a warming southerly flow this afternoon. As a result we expect warmer high temps today in the upper 60s to lower 70s after a very chilly start with early morning temps in the 30s! Skies will remain sunny today with light winds prevailing for most of the day becoming a bit breezier toward evening as the gradient tightens ahead of an approaching cold front.

&& .SHORT TERM /TONIGHT/... As of 605 AM Tuesday...As the high center moves off of the southeast coast tonight, the aforementioned cold front will approach the area late tonight. Expect some increase in high level clouds across the far north and west very late ahead of the front. The tightening pressure gradient will produce southerly breezes overnight with gusty winds along the coast and areas adjacent to the sounds. Lows will range from the mid to upper 40s inland to the low to mid 50s immediate coast. && .LONG TERM /WEDNESDAY THROUGH MONDAY/... As of 400 AM Tuesday...Fairly quiet stretch in the long term with high pressure dominating early in the week, mostly dry front moving through mid-week, and another high pressure setting up through Monday. Wednesday...Low sweeps to our north, pinching the pressure gradient with the high to our south. High pressure to our south moves offshore through the day Wednesday, causing winds to veer from southerly to westerly through the day. Wednesday looks to be the gustiest day in the long term, with ample mixing, pinched gradient, and cold front passage. Coastal plain will gust to near 25 mph, and beaches will gust to 25-30mph. Fortunately RHs will be above 35%, so fire weather should not be a concern. Highs look to be in the mid to upper 70s inland, near 70 for the coast, aided by the south veering west flow through the day. Ahead of an approaching cold front, A region of pre frontal troughing will provide enough lift for isolated weak showers in the evening. Moisture is the limiting factor for shower formation, and cloud bases will be at or above 5kft, allowing for precip to evaporate before reaching the surface. Due to the dry profile, was not comfortable with going higher than a Schc PoP for the evening hours. Dry cold front will move through Wednesday night from NW to SE. As the front moves through Wednesday night into Thursday morning, northerly wind gusts will be increasing, but should remain below 30 kts. Thursday to Monday...With the cold front now offshore, gusty conditions will prevail through the afternoon, particularly for OBX where gusts of 30mph are possible. High pressure lingers to our north Thursday, and will remain near the eastern seaboard through the end of the work week, aided by omega blocking aloft. Remainder of the long term remains uneventful due to the high. Low moving through the eastern US in the weekend will encounter this stubborn high, and some uncertainty remains on if it will be pushed north around the high, or if the high will give way. If the low moves north, we will have less chances of precip in the weekend. If the low is able to shift the high offshore, we will see increased chances of precip. No mentionable PoPs with this update for Saturday as high looks to shelter us from any incoming precip. High will shift to our south in the weekend, and easterly flow will gradually veer to become southwesterly at the start of next week. After Wednesday`s cold front, high temps gradually increase every day, above 80 inland Sunday onwards. && .AVIATION /14Z TUESDAY THROUGH SATURDAY/... SHORT TERM /Through Tonight/... As of 605 AM Tuesday...Mostly VFR conditions are expected through the TAF period as high pressure prevails through tonight. Some very shallow fog this morning will dissipate by 12Z with clear skies and light winds expected through most of today. Winds will increase by early evening and continue tonight which will inhibit fog formation overnight. LONG TERM /Wednesday through Saturday/... As of 315 AM Monday...Pred VFR conditions expected through Saturday with high pressure dominating the long term. Some isolated showers Wednesday evening will be elevated in nature, with cloud bases around 5kft. && .MARINE... SHORT TERM /through Tonight/... As of 605 AM Tuesday...Based on current and expected conditions over the next 24-36 hours we have: 1) Re-issued SCA`s for the sounds and the Alligator River and, 2) Extended the current SCA`s for the coastal Waters through Wed and Wed evening. This is to account for current elevated seas which will subside through this evening but build back up to AOA 6 ft late tonight and Wed in response to a tightening pressure gradient and increasing winds associated with an approaching cold front tonight into Wed. Northerly winds 5-15 kt this morning will become S 10-15 kt towards this evening. The S to SW winds will increase to 15-20 kt this evening and overnight with frequent gusts to 25 kt late tonight. 4-7 ft seas early this morning will subside to 3-5 ft this afternoon, then build back to 4-6 ft around daybreak Wed. The exception to this will be over the outer central waters where seas will remain 4-6 ft through tonight. LONG TERM /Wednesday through Saturday/... As of 400 AM Tuesday...6 ft seas (7-8ft for gulf stream) will linger through Wednesday from the one-two punch of the deepening low offshore Tuesday and stronger pressure gradient winds Wednesday. Wind gusts for coastal waters and Pamlico Sound will be near 25 kts during the morning/early afternoon hours Wednesday from a pinched gradient, before decreasing Wednesday evening. As a dry cold front moves southeastward Wednesday night, northerly winds will pick up behind it, gusting near 25 kts for all waters except for the Pamlico and Neuse Rivers. Stronger gusts behind the cold front Wednesday night into Thursday will be a quick hitter, and at this point it is unsure if the gusts will be handled with a SCA or a MWS. Remainder of the long term looks to be quiet with seas settling to 3-5 feet Thursday-Saturday. && .MHX WATCHES/WARNINGS/ADVISORIES...
