Marine Weather and Tides
8/26/2020 The 7 day forecast is taking about 5 seconds to load but it will eventually load. NOAA is still working on it.
8/18/2020 NOAA continues to have trouble. Wind guest will occasionally be left off graphs. I am working with NOAA to resolve the issue.
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.

SYNOPSIS. Cool high pressure will build south into the region through tonight, then weaken on Monday as cool temperatures linger. Expect a return to above normal temperatures for Tuesday and Wednesday before the next round of rain appears by Thursday ahead of a strong upper low. As this low moves off the East Coast late Friday, cool, dry high pressure will drop temperatures a little below normal for next weekend.
NEAR TERM /THROUGH MONDAY/. As of 1030 PM EDT: Radar echoes have really diminished over the last couple of hours, but there is still a few patches of drizzle out there, especially near the Escarpment. The PoPs/WX were updated to reflect the lower coverage, with mainly just slgt chc to low-end chc for the next few hours. Also made some tweaks to the temp trends to line up with obs.
Otherwise, the upper shortwave will continue to move NE of the area and offshore with heights gradually recovering through the remainder of the period as upper ridging builds to our south. At the sfc, the CAD wedge is expected to strengthen over the next several hours as its parent high slides farther east and weak low pressure eventually lifts northward just off the SE Coast. The parent high will be fairly transitory and is expected to move east of Nova Scotia tomorrow aftn, thereby eroding the CAD later tomorrow as the period ends and allowing some clearing across most of the fcst area. With the CAD in place, min temps early tomorrow will be cooler than they have been the past few days (although still above normal), but highs tomorrow will be below normal.
SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY/. As of 100 PM Sunday: Weak high pressure will remain in place over the region into Wednesday. A rather deep upper ridge will be centered off the Southeast coast, which will allow weak moist upglide to continue over the high; mostly cloudy conditions are thus expected Monday night. The dissipation of those clouds Tuesday, combined with the relatively large thicknesses, will support temps rebounding several degrees above normal. Tuesday night a moist warm front will shift north from the Gulf Coast, as TC Zeta moves northward and a cutoff upper low moves across west Texas. Precip may spread into some of our area as soon as late Tuesday night; chances increase thru Wednesday. Fcst max temps fall back slightly, mainly on account of cloudier skies.
LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/. As of 200 PM Sunday: Zeta will be caught between the Atlantic ridge and the upper low, so it generally can be expected to curve east after landfall. The operational GFS and its ensemble members are on the eastern side of the envelope, carrying the circulation close to the southern Appalachians, whereas the EC and its ensemble are more to the northwest and inland. The Canadian is closer to the GFS at the moment, but with similar storms earlier this season it flip-flopped between the GFS and EC camps, so I wouldn't place too many chips on that so-called consensus. The GFS and Canadian tracks do suggest stronger low- to mid-level winds passing over our area. That would result in stronger upslope and frontogenetic effects, in turn resulting in greater QPF potential. The resultant 0-1km and 0-3km bulk shear would also point to a TC tornado threat Wednesday night. Even if Zeta stays further west, we may not be totally out of the woods for severe wx: practically all the available guidance shows the upper low tracking across the Tennessee Valley late Thursday, and more or less through our CWA Thursday night. A slightly unstable warm sector appears likely to precede the low and attendant cold front, with enough shear to prompt a high-shear/low-CAPE damaging wind threat. Both severe and flood threats appear marginal and localized at this point, but confidence has increased to the point that we will start to ramp up messaging the potential impacts.
Cooler air and a drying trend should arrive on Friday in the wake of the front, with temps falling a little below normal. Most likely precip will end before enough cooling occurs for a p-type changeover; the remaining moisture likely will be very shallow anyway. Some frost could occur Saturday and Sunday mornings, at least in the cooler mountain/foothill locations.
AVIATION /03Z MONDAY THROUGH FRIDAY/. At KCLT and elsewhere: Widespread IFR cigs expected tonight thru at least the first half of Monday, as cold air damming persists. There are patches of -ra and dz around this evening, and that should gradually taper off thru the overnight. Wind will be in the usual CAD configuration, but become lighter. The wedge weakens on Monday, but the low clouds will take a while to improve, with complete scattering of cigs in doubt. Still expect most sites to reach VFR by late aftn, with KAND being the possible exception. The center of high pressure settles over the area late in the day, causing wind to be more variable or go calm.
Outlook: Some return of low clouds and patchy fog expected again Monday night thru early Tuesday, but CAD should completely erode by Tuesday aftn, bringing a brief period of VFR to the area. Moisture quickly spreads back in on Wednesday, as the remnants of Zeta pass by, with another round of widespread precip and restrictions likely thru at least Thursday. Dry air begins to filter in behind Zeta on Friday.

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.
