10/6/2018 Colors of tide XTide graphs changed to emphasize that they were upgraded. See next note. Comments welcome. 10/4/2018 I have fixed XTide and updated the harmonic files. There were some name changes so you might have to click EDIT to find the new station name. |

A cold front will pass through Tuesday. High pressure will then build into the region through Friday. The next storm system will affect the region this weekend. Near term through today As of 1010 am mon... Widespread ra continues this morning for all but southeastern portions of the fa. Will continue seeing area of decent WAA aloft impinge on upper wave through the morning, then lift wave moves off to the northeast and offshore by later this afternoon. Likely cat pops continue for eastern half through the early afternoon then taper off thereafter. Previous discussion... As of 7 am mon... Made some adjustment to pops based on regional radar loop. Back edge of precip presently in far southeast nc moving northeast. Maintained chance to likely pops through mid- morning, then quickly taper through the remainder of the morning into this afternoon, faster than earlier thought. No change to temps. High temps will range from the upper 50s lower 60s across the northern tier, to mid 60s south coast and southern outer banks. Short term tonight As of 2 am mon... Skies will clear out this evening as the coastal trof exits to the east. Boundary layer moisture will remain high however. Patchy late night early am fog possible. Lows in the upper 40s inland to lower mid 50s southern outer banks and south coast. Long term Tuesday through Sunday As of 230 am mon... Mostly quiet weather is expected through Friday as the flow aloft remains quasi-zonal through late week with prevailing surface high pressure in place though temperatures will be below normal. The models are starting to signal more amplification in the upper flow next beginning this weekend into early next week as the anomalously strong scandinavian upper ridge retrogrades towards greenland potentially setting up a blocking -nao -ao pattern d8+ which could result in a active and stormy pattern next week. Tuesday... A cold front with limited moisture will move through the area. Temps are forecast to warm into the 60s ahead of the front. Will continue slight chance pops though precipitation amounts will be light. Wednesday through Friday... High pressure will build over the area from the north through the period producing cool dry weather across eastern nc. Highs generally will in the 50s and lows in the 30s. A reinforcing dry cold front will move through wed night into early Thursday and 850mb temps drop below zero across the northern half of the area. Thanksgiving day looks like the coldest day with highs in the upper 40s to low 50s, coolest across the northern half of the forecast area, combined with a brisk nne wind. A hard freeze inland will be possible thu night- early Fri morning. Could see a few coastal showers fri as the flow becomes easterly and moisture increases along the se coast. Saturday through Sunday... Eastern nc will initially be on the |
warm side of the upper air amplification evolving eastern upper trough. Temps should warm well into the 60s both days but along with the warmth will come wetter conditions. Surface low development is being indicated in the gom fri, with the low moving NE through the carolinas Sat with the potential for significant rainfall and perhaps a severe weather threat fri night into sat. Still quite a ways out with significant model differences between the GFS and ecmwf. Will cap pops for Sat at high chance for now, though did add sc TSTM mention. Aviation 15z Monday through Friday Short term through tonight ... as of 7 am mon... A mix ofVFR MVFR at the 4 area terminals. Upstream obs show generally MVFR conditions which will persist into this afternoon.VFR conditions will return this evening as offshore coastal trof moves away. Light and variable winds through the period. Long term Tuesday through Friday ... as of 230 am mon... Lingering sub-vfr ceilings possible Tuesday morning, then likely lifting toVFR. Isolated showers tue, then predVFR and dry conditions expected through Friday. Marine Short term through Monday night ... as of 2 am mon... Zones look good. No changes. Weak trof of low pressure just off the coast will move east later today and tonight. Very loose pressure gradient across the marine zones today will result in winds no higher than 5-10 knots, with seas 2-4 feet. Tonight, the pressure gradient begins to tighten up a bit ahead of the next front. Winds will becoming west increase to 10-15 knots later tonight, except over the waters north of oregon inlet where winds take longer to increase, remaining less than 10 knots. Seas tonight will continue 2-4 feet throughout. Long term Tuesday through Friday ... as of 230 am mon... SCA conditions likely Thursday and Thursday night, with gusty N NE winds and elevated seas. Strong winds and dangerous seas possible this weekend with the potential for gale force winds sat. Westerly flow Tue 10-15 kt ahead of a cold front will become nw-n 15-20 kt behind the front late in the day into Tue night. 2-4 ft seas will build to 4-5 feet over the outer waters late Tue and Tue night. Wed, winds will be n-nw 10-15 kt with seas subsiding to 2-3 ft as high pressure builds over the waters. A cold front will move through the waters wed night and early Thursday with strong high pressure building in from the north. Gusty N NE winds 20-25 kt will develop, allowing seas to build to 4-8 ft Thu and Thu night. E NE flow 10-20 kt Friday, strongest south of CAPE hatteras. Elevated seas 4-6 ft could drop below 6 ft Fri afternoon for a brief period before building back above 6 ft Fri night. Mhx watches warnings advisories Nc... None. Marine... None. Synopsis...

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. |
