Marine Weather and Tides
12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed.
10/9/2019 Updated the Marine Zones.
9/4/2019 Fixed the weather maps due to NOAA moving them.
7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports.

Area Forecast Discussion National Weather Service Greenville-Spartanburg SC 340 AM EDT Sat May 30 2020
SYNOPSIS. A cold front will move into the forecast area today and track southeast through early Sunday. Dry and cooler air will mix in from the northwest Sunday into Monday, before warm and muggy summer-like weather returns Tuesday and persist through the end of the week.
NEAR TERM /THROUGH TONIGHT/. As of 325 am Saturday: Upper trough axis and associated broad/ somewhat diffuse frontal zone will progress across the region today, likely pushing east and south of the forecast area by the end of the day. This feature will likely provide some degree of focus for isolated/widely sct convection throughout the day, as drier low level air lags way behind the leading edge of the front. As a result, modest destabilization is expected this afternoon, especially across roughly the SE half of the forecast area. Actually, while the front may provide some degree of support for initiation across our southern and eastern zones, terrain effects will likely play a bigger role, due to differential heating and terrain-induced convergence zones. As such, 40-50 pops will be advertised near and just downstream (i.e., southeast) of the southern Blue Ridge escarpment. Steering currents and outflow boundaries will carry this activity southeast across the Upstate and southern NC, warranting 20-40 pops in these areas. Muted instability should preclude much of a severe weather threat with this activity, while we are unlikely to see significantly efficient rainfall rates, as PWATs return to earth. Still, wouldn't completely rule out an area of training cells/possible localized excessive rainfall, esp considering the poor antecedent conditions impacting much of the area. Convection should dissipate fairly quickly after sunset. Temps will be very close to climo through the period.
SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/. As of 230 AM EDT Saturday . A couple nice days are in store Sun and Mon as Canadian hipres supported by deep ulvl ridging slowly crosses the ern CONUS. This will keep conds dry and sfc temps a cat or so below normal each day. Dewpoints will remain below normal Sun and even a little lower Mon as a cP airmass continues to mix in from the north then northeast Thus. RH values will be quite pleasant with rather weak sfc winds to boot each day. Expect diurnal fair-wx Cu under a subs inversion with passing Ci each day. With good rad cooling conds, mins will drop a cat or so below normal Sun night then back to normal cooling Mon night as the sfc flow becomes more sw/ly after midnight. You're welcome.
LONG TERM /TUESDAY THROUGH FRIDAY/. As of 245 AM EDT Saturday: The ext range continues to show a transition to a summertime pattern as broad continental ridging takes hold and keeps sigfnt storm tracks well north and west of the SE region. However, the price to pay will be heat as Atl ridging and continued sw/ly llvl flow combines with a deeply compressed atmos and allows temps to reach right arnd 90 F outside the mtns each day. Also, sfc moisture will increase which will generate muggy feeling conds. There may be some -shra/tstms over the NC mtns by late Wed, yet these would be short-lived and relatively weak. A little more coverage of stronger diurnal tstms is probable across the NC mtns Thu/Fri as the wrn edge of the sfc ridge breaks down ahead of backdoor cold front advancing toward the FA late in the period.
AVIATION /08Z SATURDAY THROUGH WEDNESDAY/. At KCLT and elsewhere: Another challenging aviation forecast this m morning, as there are multiple competing factors that will determine cig and visby trends over the next 6 hours or so. Drier air will slowly spill in behind a broad cold front throughout the next 24 hours. However, this is unlikely to occur fast enough to preclude fog and/or stratus development, while clearing high level clouds should also contribute to increasingly favorable conditions for flt restrictions. As such, we have generally opted to advertise LIFR conditions on at least a tempo basis at all sites later this morning. Would not rule out periods of VLIFR, esp at KAVL, KHKY, and perhaps KAND. Conditions should improve at all sites by late morning.
Sufficient moisture should linger to allow for some destabilization this afternoon, with lingering frontal zone and terrain effects providing focus for initiation. Widely scattered convection should begin popping across the high terrain by early afternoon, then move southeast along outflow boundaries. Prob30s for -TSRA appear warranted at all sites but KHKY and KAVL, as convection will most likely develop just south and east of those sites.
Outlook: Dry high pressure will support quiet weather Sunday into early next week.

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.
