(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kakq 200718 afdakq area forecast discussion national weather service wakefield va 318 am edt Wed sep 20 2017 Synopsis High pressure remains centered northwest of the area through the end of the week. Tropical cyclone jose will continue to track northeast to a position off the southern new england coast later today, then meander there through the weekend. Near term until 6 pm this evening Ts jose is currently located about 200 miles south of nantucket mass and moving NE at 9 mph. The effects on sensible wx continue to pull slowly NE and away from the area today. In its wake, subsidence results in a mstly sunny and unseasonably warm day. Watching the moisture across the ky valley. Latest guidance suggests this moisture dissipates as it crosses the mts after 18z. Even the high res data suggests little if any convection makes it into the swrn most zones. Kept the forecast dry with a silent 14 pop across the swrn zones. H85 temps arnd 16c results in highs btwn 85-90 except low-mid 80s along the coast. Short term 6 pm this evening through Friday night Models suggest any evening convection to the west slides SW of the fa then dissipates after 00z across the nc piedmont. Otw, mstly clr to pt cldy and warm tonight. Lows in the mid 60s to lwr 70s. Any convection from the lingering moisture stays west and south of the fa Thursday as high pressure continues to dominate into the weekend. Expect pt to mstly sunny days with mstly clr to pt cldy nights. Highs Thursday and Friday in the low-mid 80s except 75-80 at the beaches. Lows from the lwr 60s NW to lwr 70s se. Long term Saturday through Tuesday High pressure builds over the ERN great lakes and NE CONUS early next week as the remnant low (jose) slowly circulates ese of new england. Other than periods of sc off the ocean (by the late in the weekend-early next week) ESP at the coast... Expect dry wx with above normal temps. Highs sat-sun in the mid-upr 80s except lwr 80s at the coast. Highs mon and Tue in the upr 70s-mid 80s. Lows in the low-mid 60s inland, upr 60s to around 70f at the coast. Extended models continue to struggle with the tropical systems into early next week. It may depend on where jose's low tracks which may eventually help to steer maria. The latest GFS and to a certain point the ECMWF has maria on a similiar track to what jose did (i.E. Moving north along the eastern seaboard my mid week, but how close to the coast???). To early for anything specific, but we may be doing this all over again for maria next week. Stay tuned. Aviation 07z Wednesday through Sunday Tropical storm jose will continue to lift northward through the night allowing for improving aviation conditions. MVFR ceilings across the northeast (including sby) will lift over the next couple of hours, improving toVFR after 08z. Mainly dryVFR conditions are expected for the remainder of the forecast period. An isolated shower or thunderstorm may be possible over far western portions of the region late Wednesday afternoon. Winds will be out of the N NW around 5 to 10 knots for much of the forecast period. Outlook: generallyVFR dry conditions are anticipated through the extended period as high pressure builds into the region. Marine All tropical storm warnings have been allowed to expire and replaced with small craft advisories as TS jose continues to lift north of the waters. Seas currently avg to 6-8 ft nearshore and 9-12 ft out 20 nm. Waves over the bay avg 2-4 ft except up to 4-5 ft at the mouth of the bay. Marine conditions then improve later tonight into Wed as jose pushes well off to the ne and weak high pressure builds in from the nw. Sub- sca conditions prevail Wed into Thu (except for lingering 5 ft+ seas |
on the coastal waters wed). Seas are expected to start to once again ramp up Fri into the weekend as swells from distant hurricane maria begin to affect the region so additional SCA or small craft advisory for hazardous seas will likely be needed for the coastal waters. Tides coastal flooding Tidal departures avg +1.75 to +2.25 ft over the lower bay, tapered to only about +0.5 to +1.0 feet in the upper bay. Will continue coastal flood advisories for all bay river zones through the upcoming high tide cycle this evening early Wed am. Have coastal flood warnings in effect for the zones adjacent to the atlantic ocean as water has piled up into some of the inlets and additional moderate flooding is expected through this evening's high tide, though some areas may fall a little shy of moderate criteria as the departures are starting to fall over the past 2 hrs. Also, added a coastal flood advisory for the bay side of the md eastern shore from midnight through 6 am with the expectation that tidal departures will slowly creep up with as the strong northerly winds subside later tonight and water remains piled up to some extent in the bay as waves outside of the mouth of the bay remain elevated on wed. Additional minor flooding will be possible later Wed wed night, but given the uncertainty did not extend the headlines out through this period yet. High surf advisory also remains for all coastal areas into this evening due to nearshore waves of 8-11 ft. High risk for rip currents for all beaches adjacent to coastal waters now extended through Wed as swell nearshore waves will be slow to subside.

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. |
