| Area Forecast Discussion National Weather Service Newport/Morehead City NC 935pm EST Monday Mar 1 2021 Synopsis A cold front will push through the area tonight. High pressure will build into the region from the north Tuesday followed by low pressure passing just offshore Wednesday. High pressure builds back in to round out the work week. Another offshore low could affect the area over the weekend. Near Term - Until 6am Tuesday Morning As of 930pm Mon...Latest analysis shows cold front draped over Crystal Coast. Expect a NWrly wind shift behind the front with temps dropping overnight. No changes to prev disc. Prev disc...Upper trough will depart the region tonight taking the cold front and attendant moisture with it. Shower activity will continue to struggle ahead of FROPA and only show slight chance Probability of Precipitation before midnight, drying out completely as cool high pressure builds in from the northwest. Upper level moisture stream will keep a layer of mid and high clouds overhead, keeping lows in the upper 30s inland and around 40 closer to the coast. Short Term - 6am Tuesday Morning Through 6pm Tuesday As of 350pm Mon...Upper level ridge briefly builds overhead as upper low over Texas slides eastward. Surface high pressure will shift over the mid-Atlantic and begin to erode late as a surface low begins to take shape over the northeastern Gulf of Mexico. Deeper moisture will be shunted south with sunnier conditions expected especially towards the Albemarle Sound. Much cooler with low-level thicknesses about 60-80 m lower than today, supporting highs around 50 and in the 40s for OBX with brisk northerly winds in the morning. Long Term - Tuesday Night Through Monday As of 220am Tuesday...Much cooler and dry for Tuesday, followed by more rain Wednesday as a low pressure area tracks offshore, then dry again late week with another high building in. There are mixed signals in the models regarding a possible coastal low and it's impacts on Eastern NC during next weekend. Tuesday night through Wednesday...Better model agreement on upper pattern by midweek, as they are converging on a solution with the next shortwave ejecting out of the Four Corners region early in the week, passing through the TN Valley on Tue, and then through the SERN CONUS mid week. The latest guidance is suggesting that the onset of precipitation will hold off until after midnight Tuesday night and that there will be a south to north moisture gradient Wed, with areas south of Highway 264 having the best chances for rain and the highest amounts. Will forecast categorical Probability of Precipitation south, likely central, and will only have chance northeast zones based on the 0Z model run. Temps near climo this period, with highs in the 50s to lower 60s and lows 35-45. Thursday through Friday...High pressure will build over the area with dry weather expected and a reinforcement of the cold temps Fri. Temps will be near climo due Thu, dropping below normal on Fri. Saturday and Sunday...Looks like low pressure will be developing off the southeast coast this weekend. The track of this system will be critical to how much wind/precipitation impact's there will be across Eastern NC. There is still lack of run to run continuity and differences in the models, with areas east of Highway 17 having the best chance of precipitation which at this times looks like a cold rain. This is almost a week away so expecting a lot of variance in solutions over the next couple of days but will continue to monitor. Marine Short Term /Tonight and Tomorrow/...
