5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues. |

Area Discussion for - Newport/Morehead City, NC
(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus62 kmhx 181931 afdmhx area forecast discussion national weather service newport morehead city nc 331 pm edt Mon jun 18 2018 Synopsis An offshore high inland trough pattern will continue through mid week producing a hot southwest flow across the area. A weak frontal boundary may move into northern sections Tuesday night and Wednesday with a somewhat stronger front pushing through the area Thursday. Near term through tonight As of 3 pm Monday... Latest sfc analysis shows 1021mb high pressure anchored off the SE coast with a weak trough stretching e-w across nc from approx charlotte to manteo. A moist and unstable airmass remains in place with kmhx 12z sounding shows pw values of 2.16" with CAPE analyzed around 3500-4500 j kg. Convection is developing along the aforementioned trough as well as the sea breeze boundary and expect scattered convection to continue into the early evening hours, then gradually diminish with loss of sfc heating and expect dry conditions through the rest of the overnight. The heat continues to build today with temps in the low mid 90s inland bringing heat indices to around 100-105f with a few locations slightly higher this afternoon. Very mild and muggy conditions expected tonight with lows only in the mid to upper 70s. Short term Tuesday As of 315 pm Monday... The upper ridge builds aloft Tuesday bringing additional heating but also should serve to help suppress diurnal convection. High res models do show thunderstorm development during the afternoon but global models and MOS guidance showing very low pops. Given the heat, moisture and instability cannot completely rule out an isolated storm and decided to keep slight chance pops during the afternoon. In addition, a weak front will be pushing south through the mid- atlantic states trough the day and some models showing some storms skirting northern counties late in the day, but will likely be early evening. The big story will be the heat with temperatures topping out in the mid to upper 90s inland and low to mid 90s coast. Heat indices expected to top out around 105-110f and will issue a heat advisory for all areas. Long term Tuesday night through Sunday As of 330 am Monday... Latest guidance continues to indicate upper ridge building east over area through midweek, resulting in very hot and humid conditions for tue-wed, with highs in mid to upper 90s and heat indices 105-110 degrees. A weak frontal protrusion into northern sections is indicated early Wednesday, then a stronger front will push in late Thursday into Friday. Tuesday night through Wednesday... A strong upper level ridge will build over the lower mississippi valley through midweek. At the surface, high pressure will be centered well offshore, and ridge into the SE us, while a weak trough forms over central nc. Increasing low level heights through Wednesday will support high temperatures in the mid to upper 90s inland, and the upper 80s to low 90s near the coast. Wednesday will continue to be oppressive with dewpoints in the mid to upper 70s, and heat indices climb to around 110 degrees. Overnight low temperatures will be very mild ranging from the low to upper 70s. Latest guidance has trended to just isolated convective precip threat tue-tue night due to building ridge, then a better chance wed- wed night as ridge flattens slightly and allows weak surface front to push into northern half of area. Thursday through Saturday... Initial frontal boundary will dissipate over area early Thursday, then main models in general agreement that stronger shortwave will break down ridge enough to allow frontal push through entire area Thu night into Friday. Front lifts back north by Saturday morning with return of inland thermal trough pattern for rest of weekend. Main change with this forecast issuance was to increase pops to 50% for most of area Thu afternoon and southern sections Thu night, then mainly 20-30% pops rest of period. Temps in low to mid 90s and heat indices around 105 again for thu, then 5-8 degrees cooler for fri-sat and back into lower 90s Sunday. Low temps will continue to be mild, mostly in the 70s.

Short term through 18z Tuesday ... as of 158 pm mon...VFR forecast for the period as typical summertime offshore high inland trough pattern will continue. Scattered showers and storms still expected to develop now into the early evening, with the best chances at ewn and oaj along the seabreeze. Periods of sub-VFR are possible with directly impacting storms. Long term Tuesday through Friday ... as of 400 am Monday...VFR conditions are expected through most of the long term, with the exception of temporary subVFR conditions possible each day due to scattered thunderstorms. Some sub-vfr CIGS will be possible with ne-e flow behind front Friday into Friday night. Marine Short term through Tuesday ... as of 315 pm Monday... Latest obs shows SW winds 5-15 kt north of oregon inlet with seas around 2 ft, and 10-20 kt south of oregon inlet with seas 3-5 ft. An offshore high inland trough pattern will continue through the short term bringing typical diurnally enhanced wind pattern. SW winds are expected to increase a bit more late this afternoon and evening with inland heating bringing SW winds to around 15-25 kt across the central and southern waters. Seas expected around 2-4 ft through the period but could see some 5 ft seas across outer waters south of hatteras late through tonight. Will continue with a marginal sca for the waters south of hatteras, developing later this afternoon evening into tonight. Long term Tuesday through Friday ... as of 400 am Monday... Southern half of waters will continue to see SW winds mainly 10-15 kt into thu, while northern half will see shifting and variable conditions due to weak front pushing in from north late Tue into wed. Stronger front now expected to push through all waters late Thu into Friday, producing ne-e winds 10-15 kt. Seas mainly 2-4 feet during period.
