Area Forecast Discussion . UPDATED National Weather Service Newport/Morehead City NC 155 PM EDT Sun May 31 2020

SYNOPSIS. High pressure will build into the Carolinas through midweek. Another cold front will approach from the northwest Thursday into Friday.

NEAR TERM /THIS AFTERNOON/. As of 150 PM Sunday . Ongoing forecast remains in good shape. Latest surface analysis illustrates the cold front well off the NC coast, stretching from Charleston SC to several hundred miles off the coast of Cape Hatteras. A strong 1029mb centered over the upper Mid-West and Great Lakes will continue to gradually build in from the NW this afternoon. Blended total precipitable water imagery further illustrates the airmass drying over Eastern NC, with PWATS now around 0.9 inches or 75-80 percent of normal for late May. 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 lower 60s inland to upper 60s along the coast, but will fall into the 50s this afternoon.

SHORT TERM /TONIGHT/. As of 220 AM 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 will fall to around 0.5", haven't seen it that low here in a few weeks.

LONG TERM /MONDAY THROUGH SATURDAY/. As of 330 AM 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 Mon 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 PoPs 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.

AVIATION /18Z SUNDAY THROUGH FRIDAY/. Short Term /Through 18Z Monday/ . As of 150 PM Sunday . VFR conditions will prevail through the TAF period due to strong high pressure building southeast over the sites. Winds subside some tonight, but do not completely decouple, while dew points fall to around 50. Overall conditions do not support widespread fog or low stratus overnight. The surface ridge north of the area will continue to build south over Eastern NC on Monday yielding VFR conditions.

Long Term /Monday through Thursday/ . As of 4 AM Sunday . Pred VFR expected through much of the long term with generally dry conditions prevailing, however shower chances begin to increase late in the period bringing brief periods of sub-VFR conditions.

MARINE. Short Term /Through Tonight/ . As of 945 AM Sunday . Latest surface and buoy data indicate NNE winds 15-25 knots with gusts to 30 knots for the coastal waters and Pamlico Sound, where the best gradient exists between the cold front offshore and high pressure building in from the northwest. Seas range 4-6 ft north to 2-4 ft south, but expect deteriorating conditions to spread south this morning, as northerly surge shifts through the central and southern waters. Gusty northerly surge 15-25 kt expected behind the front continuing through the evening. SCA continues for the waters and sounds. Seas will build to 4-7 ft today. Winds and seas will slowly subside tonight and early Mon morning. NE winds diminishing to 10-20 kt late tonight with seas subsiding below 6 ft early Mon morning.

Long Term /Monday through Thursday/ . As of 415 AM Sunday . High pressure building over the waters Mon 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 Tue night into Wed 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.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
