| Area Forecast Discussion National Weather Service Newport/Morehead City NC 713pm EDT Wednesday May 5 2021 Synopsis A cold front will push through the area tonight. A low pressure system will impact the region late week with cooler weather this weekend. Near Term - Until 6am Thursday Morning As of 710pm Wednesday...Latest mesoanalysis and convective data shows a rather stable airmass in place across eastern NC this evening with surface-based CAPE values of 500-1000 J/kg with mostly W/WNW flow aloft. With the atmosphere less conducive to support deep convection, Storm Prediction Center has removed the Marginal threat area from our CWA this evening. Based on current trends, may not see much precipitation at all in our CWA this evening. Lowered PoPs to slight chance over all but the far western/northern tier which will be a bit closer to the mid-level support, but overall scant rainfall expected this evening, especially near the coast where the rainfall is especially needed. Cold front will shift offshore after midnight with breezy and cooler conditions expected. Lows by morning in the 55-60 degree range for most all of the CWA. Short Term - 6am Thursday Morning Through 6pm Thursday As of 400pm Wed...Thursday will see weak high pressure form behind the front over northeastern North Carolina which will keep conditions cool and dry with high temperatures topping out in the low 70s inland with mid 60s along the coast. Winds over the water will remain breezy at least through theam hours. No precipitation is expected. Long Term - Thursday Night Through Sunday As of 325am Wed...High pressure will briefly be in control Thursday. Low pressure is expected to develop off the coast Friday and bring wet conditions to close out the work week. The weekend appears dry before the next frontal system impacts the area. Thursday...High pressure briefly builds into the the Carolinas behind the departing front with much cooler air settling over the region. Highs expected in the low 70s inland but with a cool northerly wind OBX will likely get only into the mid 60s. Friday...Lobe of upper energy is expected to pivot a quasi- stationary low centered over the Hudson Bay late Thursday into Friday morning, helping to spur development of a coastal low off the NC coast. Shower development is expected to increase late Thursday through Friday, coming to an end late in the day as the low lifts towards the New England coastline. Highs still on the cool side, hovering right around 70. Saturday through Tuesday High pressure builds in from the west for the weekend ushering in dry and moderating conditions. Temperatures rebound into the 80s by Sunday and Monday with increasing southwesterly flow. Next frontal system approaches the region sometime Monday and is expected to stall over the Carolinas to close out the period. Temperatures dip back into the mid to upper 70s. Marine SHORT TERM /Tonight/... As of 710pm Wednesday...Winds at early evening are SW at 15-20 knots with seas 3-5 feet. Latest HRRR/3km NAM show an increasing wind trend behind moderately strong cold front that moves offshore after midnight. Northerly surge 15-25 kt expected behind the front early Thu morning. SCAs (Small Craft Advisories) continue for the waters south of Oregon Inlet and the Pamlico Sound as well as Neuse/Bay rivers which will drop off this evening. SCA (Small Craft Advisory) conditions likely to develop across the northern waters and Albemarle Sound region behind the front tonight. Long Term - Thursday Through Sunday As of 340am Wed...SCA (Small Craft Advisory) conditions are likely to linger for Thursday morning with northerly surge coming to an end. NNE winds 10-15 kt in the afternoon will back NW as coastal low develops offshore and lifts northward towards New England. Guidance beginning to come into agreement that at least SCA (Small Craft Advisory) conditions appear probable in the low's wake, but want to see a little more consistency before explicitly showing these conditions in the forecast. High pressure builds back over the waters for the weekend with calming winds, then moves offshore with increasing southwesterly SCA-level winds. Seas fall to around 2 feet by late Friday, then building to at least 2-4 feet by Friday night into Saturday. Seas fall back to 2-3 feet for Saturday night and Sunday before quickly building to 5-6 feet with SW surge.
