SYNOPSIS. Seasonably cool and dry conditions will persist through the weekend. A couple weak surface lows will bring precipitation to the area Monday and again during the middle of next week. There is the potential for a fairly strong and moist weather system to affect the region by next weekend.
NEAR TERM /THROUGH TONIGHT/. As of 645 AM: A vertically stacked low pressure system will move from the Ohio Valley into the Great Lakes region today. Warm air aloft associated with the occlusion will preclude mixing, and will maintain low cigs and fog across portions of the Piedmont this morning. Patchy dense fog returned in the NC Foothills after having cleared out earlier, but likely will linger until the stratus dissipates.
The secondary front will bring a resurgence in low-level moisture to the western slopes of the Appalachians, as winds eventually turn northwesterly across the area. Chilly temps will allow snow to develop near the Tenn border where not already. However, relatively weak winds and temperatures above -10C in the upslope layer suggest accumulation will be too small for an advisory. At least occasional light showers or flurries are likely to occur into Sunday along the border northeast of the French Broad Valley.
Max temps will be below normal across the mountains, but despite the cold fropa, near normal in the rest of the area thanks to the with the offsetting effects of downsloping and sunshine. Mins tonight will be slightly above normal over most of the area.
SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/. As of 240 AM Saturday: An active pattern continues over the short term . yet mainly across the NC mtns. The upper flow becomes more zonal Sun . however waves of energy will traverse the flow before a s/w approaches the FA Sun night. This feature will bring a weak yet moist sfc trof to the mtns . thus PoPs have been increased to likely across the NC/TN spine before sunrise Mon. Partial thicknesses generally remain in the mixed zone . but soundings show a better chance of snow than rain across the far wrn NC mtns and elevations abv 3.5 Kft. Will expect light snow to begin late Sun evening continuing thru the overnight before tapering off by mid-day Mon. The best rates will coincide with the aforementioned h5 s/w which will likely produce arnd a couple inches over the wrn Smokies and places like Mt Mitchell. Snowfall amts will drop off quickly over lower elevation with perhaps a trace at KAVL in flurries or a -ra/sn mix With increasing cloud cover. mins on Mon will remain abv freezing except across the higher elevs . while better rad cooling Mon night will allow temps to drop arnd normal. Max temps will reach normal levels each day as winds remain sw/ly Sun . briefly shift nw/ly with the sfc trof passage . then return w/ly by Mon afternoon in clearing skies outside the mtns.
LONG TERM /TUESDAY THROUGH FRIDAY/. As of 320 AM Saturday: A dry quiet day is in store to begin the period as the latest guidance agrees well with a confl pattern aloft and weak hipres engulfing the FA. The models are having a hard time with a complex split flow pattern Wed into Thu, however. The CMC has been fairly consistent with a moist nrn GOM low affecting the area with a good amt of precip over two days . however the ECMWF and GFS continue to have much drier solns. It doesnt help that 60 RAOB soundings didn/t make it into the 00z GFS run due to data ingest issues . yet overall the model is similar to ECMWF and is inline with it/s previous run. Will side with the drier idea of the GFS/EC and taper back PoPs due to the overall model spread uncertainty. Still believe there will be a sfc low across the nrn GOM Wed/Thu . but the amt of suppression could be too great for much of a precip or wintry wx issue. Have a -sn/ra mention for the mtns but with PoPs so low . will not advertise amts which would be pretty low right now anyway. Another more robust system looks to develop over the area outside of the fcst timeframe . however there are large differences in the individual model solns and quite a bit of spread seen in the ensembles. Yet, this could be a system to keep an eye on for the weekend.
AVIATION /12Z SATURDAY THROUGH WEDNESDAY/. Stratus mainly at IFR level remains across the Piedmont following the damp weather yesterday, affecting all sites at the beginning of the period except KAVL and KAND. A secondary cold front will gradually scour out the moisture and restrictions this morning, with all restrictions expected to end by 15z. Brief decline to LIFR cig is possible especially at KCLT, which has prompted a TEMPO mention. Westerly flow into the Appalachians will produce SHSN at high elevations along with persistent cloud cover near the Tennessee border. Some of these clouds will be seen over KAVL during the period. Winds will veer to WNW at KCLT and the other Piedmont sites late this morning.
Outlook: VFR conditions are expected Sunday. A passing disturbance may bring precip and some restrictions on Monday, but otherwise most of the work week will be VFR.

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.
