A cold front moves across the area Thursday night, then stalls along the virginia-north carolina border Friday before pushing south into the carolinas Saturday. High pressure builds into the area for the later half of the weekend. Near term through tonight As of 640 am edt Wednesday... shwrs are slowly disspiating as they lift nne across the piedmont over the past few hrs. Expect another hot humid day with sct convection dvlpng due to the s W lifting NE from the carolinas and sfc trof east of the mts. Spc has the NRN half of the local area in a marginal svr risk with the main threat being strong to damaging wind gusts. Like yesterday, any storm will be capable of producing hvy downpours and freq lightning. Skies avg pt sunny. Maintained chc pops. Highs upr 80s-lwr 90s. Sw winds 10-20 mph. Sct convection continues thru 06z tonite then dissipates. Otw, pt cldy warm humid. Lows 70-75. Short term Thursday through Friday night As of 330 am edt Wednesday... will keep a persistant forecast going thurs for mainly diurnal convection firing up along the sfc trof during the aftrn eve ahead of the cold front apprchg from the nw. Maintained chc pops (30-50% highest west). Ahead of it, enuf heating to push temps back up into the low-mid 90s before any convection dvlps. Heat index values arnd 100 degrees. Models continue to slow the southern movement of the cold front thurs nite, now to a position across central va by 12z fri. Kept chc pops except low end likely across the ERN shore as this bndry slowly sags south thurs nite. Mstly cldy with lows in the 70s. Interesting setup Fri fri nite as the front is progged to stall near the va nc border Fri aftrn with a few waves of low pressure progged to move east on it Fri nite. This will enhance the pcpn threat especially across the SRN half of the fa. Have increased pops to high end likely for now. Could be looking at some training storms leading to some potential flooding issues. Highs Fri in the 80s. Rain tapers off (but does not end after midnight) Fri nite. Lows mid 60s-lwr 70s. QPF 1-2 inches across the SRN half of the fa. Wpc has us in a marginal day 2 ero risk. Long term Saturday through Tuesday As of 330 am edt Wednesday... low pressure moves east into the vacapes erly sat. The movement of the low combined with high pressure building in from the nw will allow the front to sink south into SRN nc Sat aftrn. Enough lingering moisture behind this bndry to keep chc pops going thru the day sat. More clouds south with some pt sunny skies north by the aftrn. Much cooler with highs ur 70s-lwr 80s. Shower TSTM chances continue Sun over S SW portions of the cwa as ridging aloft sets up off the sc ga coast and our region goes under moist wsw-sw flow aloft while sfc ridging builds into the area. Have 30-40% pops for SRN va NE nc. Continued chances for mainly aftn-evening showers tstms early next week as weak troughing tries to re-establish itself from the great lakes to the deep south |
and deep layer moisture continues to stream into the region from the sw. Highs mainly in the low-mid 80s through Mon with lows in the 60s (except for some low 70s in coastal SE va NE nc). Slightly warmer by next Tuesday with highs mainly in the mid 80s. Aviation 12z Wednesday through Sunday As of 640 am edt Wednesday... vfr conditions should prevail through the forecast period. The exception will be for anthr day of aftrn eve convection that fires up along the lee trof and weak low pressure moving across nc later this morning and erly aftrn. Kept thunder out of the forecast ATTM given low confidence of timing convection at any one TAF site, but did include vcsh and a bkn CU deck after 18z. Sw winds 10-20 kts this aftrn. Outlook... more of the same Thursday as addntl late day eve convection dvlps along the lee trof. A cold front slowly moves across the local area thurs nite then stalls across nc fri.

Marine As of 330 am edt Wednesday... small craft advisories are now in effect for the northern coastal waters, ches bay, and currituck sound this afternoon into Thursday morning. Current observations show SW winds of around 10 to 15 knots over the waters with seas of 2 to 3 feet and waves in the bay of 1 to 2 feet. Expect winds to steadily increase through this afternoon and evening as a cold front approaches the region from the west. Winds become S to SW at around 15 to 20 knots late this afternoon into tonight with gusts of 20 to 25 knots. Latest wind probability guidance continues to highlight the northern coastal waters and ches bay for at least low end SCA conditions through tonight, thus a sca is now in effect beginning later this afternoon. Seas will also be on the increase through the day, building to 4 to 5 feet across the north by tonight. Winds decrease below SCA levels Thursday morning as the pressure gradient relaxes. The aforementioned cold front slowly drops south across the waters early Friday before likely hanging up near or just south of the va nc border. Winds turn to the n NW behind the front.

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. |
