Area Forecast Discussion National Weather Service Newport/Morehead City NC 159 PM EDT Sat Jul 11 2020

SYNOPSIS. A weak front will approach the region this afternoon then stall and gradually dissipate Sunday into Monday. Bermuda high pressure will then build into the area early next week, with an inland lee trough over the piedmont.

NEAR TERM /UNTIL 6 PM THIS EVENING/. As of 1220 PM Saturday . Some fair-weather cumulus developing across inland areas as band of mid clouds exits the coast at early afternoon. High resolution guidance continues to indicate very little in the way of convective development through most of the afternoon, until late afternoon/early evening when the weak front in the eastern Piedmont starts to cross the area. PoPs were lowered earlier to 20-30 percent and no changes needed to that for this update. High temperatures will be in the low to mid 90s inland, and 85 to 90 coastal areas.

SHORT TERM /6 PM THIS EVENING THROUGH 6 AM SUNDAY/. As of 240 AM Sat . Shra and storms that develop this aftn will grad diminish and shift twrd cst overnight with bulk of region dry after 06Z. SW flow will cont with muggy lows once again in the 70s.

LONG TERM /SUNDAY THROUGH FRIDAY/. As of 3 AM Sat .

Sunday . Showers and storms primarily along the sea breeze, otherwise another hot day with highs getting into the mid 90s inland.

Monday . The last day that we will be under the influence of the trof and by late afternoon, a short wave will approach from the west. Increased rain chances here into the likely range to account for the better upper level support. Highs again well into the 90s.

Tuesday - Friday . Little day to day change with the trof mentioned above lifting out, and high pressure aloft building across the Carolinas. Typical daily convection will be possible especially along the sea breeze, and continued no higher than a 20 to 30% through the period. Temps will be summerlike or well into the 90s away from the beaches.

AVIATION /18Z SATURDAY THROUGH THURSDAY/. Short Term /through 18Z Sunday/ . As of 145 PM Saturday . VFR conditions will prevail throughout the TAF period. Winds out of the SW at 7kts or less. SCT cu field presently developing across the area could lead to showers with possibility of thunderstorms late this afternoon (21Z) leading to temporary sub VFR conditions, but confidence was low so only a tempo group was included. Any storms that do develop will subside by 00Z. Overnight partly cloudy skies limit cooling and while winds are expected to calm slightly, they are expected to remain around 5kts, putting a damper on the possibility of fog developing in the early morning hours.

Long Term /Sunday through Wednesday/ . As of 145 PM Sat . Mainly VFR through the period. Potential for brief MVFR restrictions especially during the afternoon in periods of showers or thunderstorms. Early morning fog also possible in the footprint of afternoon/evening rainfall.

MARINE. Short Term /Through Tonight/ . As of 1220 PM Saturday . Winds currently SW 10-15 knots with seas ticking up to 3 to occasionally 4 feet at early afternoon. Seas should increase to 3-5 feet as the day wears on with winds increasing to 15-20 knots later this afternoon and evening. A few gusts 20 to 25 kt poss late today and early tonight but overall speeds shld remain below SCA lvls. Seas could flirt with 6 feet tonight outer central wtrs but will cap at 5 ft for now.

Long Term /Sunday through Wednesday/ . As of 300 AM Sat . Large swell will be the main boating concern during the long term period, especially Sunday night through early Tuesday.

Southwest winds mainly 10 to 20 kts Sunday through Tuesday. As winds peak Sunday night into Monday a few gusts to near 25 kts are possible. A building swell will push waves to 3 to 5 feet Sunday. While NWPS still suggest 6 foot wave Sunday, both the national blend and Wave Watch show 6 footers holding off until Sunday night, so we will continue to cap waves below 6 feet through Sunday afternoon. 5 to 8 foot wave possible Monday, before subsiding to 3 to 5 feet Tuesday. The boating pick of the week will be Wednesday with south winds less than 10 kts, and waves under 3 feet.

MHX WATCHES/WARNINGS/ADVISORIES. NC . Beach Hazards Statement until 8 PM EDT this evening for NCZ196- 204-205. MARINE . None.

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.
