Marine Weather and Tides
Version 3.4 |
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. |

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kokx 242003 afdokx area forecast discussion national weather service new york ny 403 pm edt Fri may 24 2019 Synopsis High pressure builds across the area tonight and then offshore early Saturday. A warm front will then move through the area toward daybreak Sunday, followed by a cold frontal passage at night. High pressure briefly follows on Monday. Another warm front then moves through the area on Tuesday, with a cold front following for Thursday into Thursday night. Near term until 6 am Saturday morning High pressure builds in aloft and at the surface tonight. Nw winds will quickly diminish this evening, becoming light and variable overnight. Dry conditions and light winds will allow outlying areas to fall into the upper 40s, with the mid to upper 50s in and around the nyc metro. Short term 6 am Saturday morning through Saturday night Upper ridge axis pushes offshore in tandem with the low-level ridge on Saturday. A return southerly flow will gradually strengthen with some gusts up to 20 mph in the mid to late afternoon hours. Highs Saturday will top out around 70 at the coast and in the low to mid 70s elsewhere. Clouds will be on the increase in the afternoon as warm advection ensues on the back side of the ridge. Mid and high level clouds will filter in by early evening with a chance of showers and isolated thunderstorms. The best chance looks to be after midnight and across ct and eastern li, where the best thermal forcing and moisture advection will take place. Rainfall amounts should be light and generally less than a quarter inch. Lows will be in the upper upper 50s. There is a low risk for the development of rip currents Saturday. Long term Sunday through Friday |
Any warm advection precipitation in the morning on Sunday will quickly move east giving way to mostly sunny skies and above normal temperatures as offshore, westerly flow develops. By evening, the next short wave passes to the north, with the attendant cold front moving through. Although coverage may be isolated, model soundings indicate nearly unidirectional west-northwest flow that strengthens with height, about 50-60 kt deep layer shear and mid-level lapse rates of around 6.5 c km that will support stronger updrafts and potentially hail. Additionally, a dry subcloud layer may enhance any downdrafts, so expect a few clusters of storms with strong winds to be possible. The loss of diurnal heating will gradually allow these storms to weaken overnight. Brief high pressure for Monday will lead to mostly tranquil weather, with temperatures briefly closer to climatological normals. The high moves offshore Tuesday, allowing a return to warm advection with a front slowly moving northeastward through the region, which may spark a few thunderstorms. We then stay solidly in the warm sector for Wednesday and Thursday, with temperatures well above climatological normals and an increasing chance for diurnal thunderstorms. Once again although forcing for ascent is weak and confined to a subtle short wave and surface trough for Wednesday, steep low and mid level lapse rates may contribute to a few stronger cells. Chances of strong thunderstorms then increase into late Thursday with the approach of a cold front, especially with the increasing wind field as the upper trough nears. The front then passes through overnight, marking a return to more seasonable conditions. Aviation 20z Friday through Wednesday High pressure builds over the region this evening, then offshore tomorrow. Vfr. NW winds mostly around 20 kt with gusts near 30 kt, weakening late this afternoon into this evening and gusts ending by midnight. Winds become light and variable tonight, then southerly on Saturday as the high moves offshore.

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. |
