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.

Area Forecast Discussion National Weather Service Greenville-Spartanburg SC 1235 AM EST Sun Jan 19 2020
SYNOPSIS. A cold front will cross the forecast area tonight, ushering in Canadian high pressure for most of the upcoming work week. Expect this high pressure to bring below normal temperatures to the region. The next front with low pressure will not approach the area until the end of the week.
NEAR TERM /THROUGH TODAY/. As of 1235 AM: Rain is moving out of the area as a cold front moves through. Have updated for current and expected precip dissipation. Temps are warmer over the mountains than the piedmont. Expect that to change as the front moves through and made adjustments for that. Winds will become gusty over the mountains behind the front.
Otherwise . the cold front pushes thru late tonight. Little moisture is depicted in the colder air, so only a brief opportunity for snow exists in the NW-flow affected areas along the Tenn border. Temps will however continue to plummet up there, and wind gusts to increase, into mid-morning Sunday. Mins still look to be above normal overall. Gusts will remain below advisory criteria; wind chills fall to near zero for a time in the morning but warm again on the diurnal curve. No precip is expected during the daytime hours. Temps top out a category or two below normal in the mountains and I-40 corridor, and around normal elsewhere in the Piedmont.
SHORT TERM /TONIGHT THROUGH TUESDAY/. As of 130 PM EST Saturday: Upper heights continue to drop thru the short term while a vigorous h5 s/w trof develops over the Midwest and swings across the FA by early Tue. The atmos will be quite dry through a deep layer as the trof approaches and llvl winds will remain advectively dry . so dont expect much more than mid-clouds with this upper feature thru Tue afternoon. The big story over the short term will be the temps. Models show moderate llvl CAA continuing early Mon and waning by the afternoon as llvl thicknesses broaden. With a cP high builds in . lows Mon will drop into the teens over the mtn valleys and m20s across the non/mtns. The higher peaks will likely have WC values in -5 degree range thru daybreak as winds persist arnd 15 kts along with low-end gusts. Periods of mlvl moisture and temps beginning the day so cold will hold max temps abt 5-8 degrees below normal on Mon. Very good rad cooling conds develop Mon night which will lead to the coldest temps of the period. Mins shud bottom out arnd 10 degrees below normal over the FA. Another cold day in the L40s non/mtns and m30s mtn valleys Tue as the cP airmass struggles to warm even within max insol.
LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/. As of 210 PM EST Saturday: An upper level ridge begins to build across the SE states early Wed. This ridge will cross the fcst area and dominate pattern into Fri At the sfc. high pressure will remain centered over the mid/Atl with broad ridging aligned across the FA. These features will keep the atmos deeply dry while a subs inversion is maintain arnd h85. Surface winds will remain generally out of the E to NE during this time . so expect only a modest warm-up of both max and min temps to arnd normal by Fri. The models continue to show a closed low developing over the srn Plains Fri morning with an occluded sfc low tapping into a wide open GOM. The ECMWF model has come more inline with the GFS upper pattern . however the model still brings in isent lift precip abt 6 hrs quicker than the GFS. This is due to a stronger and drier sfc high seen over the the east coast on the GFS In any regard. thermal profiles indicate a low chance for wintry precip . mainly diurnally driven -snsh or -ra/sn mix across the higher NC mtn elevations and NC NW Piedmont Thu night. The sensible wx fcst for Fri will likely change to some degree over the next few days with such a dynamical system in play and the possibility of colder/warmer air in the low levels.
AVIATION /06Z SUNDAY THROUGH THURSDAY/. At KCLT and elsewhere: A mixed bag of flight category remains across the region as a cold front slowly crosses the area. Precip will move out by 09Z with some improvement in cigs and vsby. All restrictions should scatter out and clear by daybreak. Wind will generally be SW through daybreak with NW wind and developing gusts at KAVL. W to NW winds become gusty during the morning and remain there into the evening. KAVL will see stronger NNW wind and gusts. MVFR mountain clouds return during the day and remain overnight. Uncertain if a cig develops at KAVL. Otherwise, clear skies expected.
Outlook: VFR at least through the middle of the week under cold dry high pressure.

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.
