National Weather Service Newport/Morehead City NC
420am EDT Sunday May 31 2020
High pressure will build into the Carolinas through midweek. Another cold front will approach from the northwest Thursday into Friday.
Near Term - Through Today
As of 220am Sun...Latest surface analysis shows cold front pushing through coastal NC, with strong 1027mb centered over the upper Mid- West and Great Lakes. The front will push off the coast shortly and the high will gradually build in from the NW today. Very pleasant weather expected today as a cooler and drier airmass filters into the area. Low level thickness values and N/NE flow support highs ranging from the low 70s across the NE to upper 70s across the SW. Dewpoints currently in the upper 60s to low 70s early this morning will fall into the 50s this afternoon. Should be a mostly dry day, but cannot rule out an isolated shower developing along the southern coast this afternoon.
Short Term - Tonight
As of 220am Sun...Quiet and pleasant night expected with high pressure in control. Below normal temps expected overnight with good radiational cooling setup allowing lows to fall into the low 50s inland and upper 50s along the beaches. PWATs (Precipitable Waters) will fall to around 0.5", haven't seen it that low here in a few weeks.
Long Term - Monday Through Saturday
As of 330am Sunday...High pressure will bring drier and cooler conditions Monday and Tuesday. The high will move offshore by the middle of the week with southwest flow bringing much warmer temperatures through the end of the week. A series of disturbances will bring rain chances back into the forecast late week into next weekend.
Monday through Tuesday...The high will be centered across the area Monday, then slides offshore Tuesday. NW downslope flow aloft will generally bring dry conditions but a weak shortwave and warm front will move across the region late Tuesday/Tuesday that could trigger a very isolated shower, but forcing and upper level support will be weak. Dewpoints in the 40s and 50s will continue to bring comfortable conditions for early June. Temps Monday will be around 5-10 degrees below normal with highs in the 70s and lows in the 50s. Southwest return flow develops Tuesday with temps warming into the lower 80s inland.
Wednesday through Saturday...High pressure will be centered well offshore through the period with a series of weak disturbances moving through the WNW flow aloft for the remainder of the period which will bring a chance of showers across the area, especially from late week into next weekend. Models have wavered some with timing and coverage of pcpn, so will limit Probability of Precipitation to slight chance to low chance at this time. The best chances may come Friday into Saturday as a more robust shortwave moves across the area and a weakness in the ridge across the South allows more Gulf moisture to advect north into the area. SW return flow around the high offshore will bring much warmer temps with highs in the upper 80s to lower 90s inland with mid 80s along the beaches.
Short Term Through Tonight
As of 220am Sun...The front is now pushing through the central and southern waters. Latest obs show N/NE winds 5-10 kt behind the front and WSW 10-15 kt ahead of it, with seas 2-4 ft. Expect conditions to deteriorate quickly early this morning, shortly after sunrise. Gusty northerly surge 15-25 kt expected to develop behind the front continuing through the evening. SCA (Small Craft Advisory) continues for the waters and sounds. Added Albemarle Sound and adjacent waters thinking there would likely be several hours of freq gusts to 25 kt. Seas will build to 4-6 ft today. Winds and seas will slowly subside tonight and early Monday morning. NE winds diminishing to 10-20 kt late tonight with seas subsiding below 6 ft early Monday morning.
Long Term - Monday Through Thursday
As of 415am Sunday...High pressure building over the waters Monday will result in diminishing winds and subsiding seas. High pressure will slide offshore by Tuesday with SW winds increasing to 15-25 kt in the afternoon. Strong SW flow 20-25 kt will prevail Tuesday night into Wednesday night with seas around 5-7 ft. SW flow will decrease to 15-20 kt Thu with seas forecast to subside from 4-6 ft to 3-5 ft Thu night.
