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 160147 afdokx area forecast discussion national weather service new york ny 847 pm est Fri feb 15 2019 Synopsis A cold front passes through this evening, followed by high pressure building in through Saturday night. Weak low pressure passes just south Sunday night and Monday. High pressure builds Tuesday, followed by another low pressure and frontal system mid week. Near term until 6 am Saturday morning The okx VWP and radar suggest a strengthening lljet ahead of the cold front. As a result, sct shwrs have been fcst for ern portions of LI and ct, with a few sprinkles wwd to the hudson valley. The hrrr and 18z NAM are dry. Areas could trace and not measure. Otherwise, the fcst is on track, with the front entering orange county and poised to pass thru the CWA thru midnight. Dry weather for the overnight hours as high pressure builds in. Cloud cover and or strong enough winds will hold low temperatures to above normal levels. Short term 6 am Saturday morning through Saturday night Surface high pressure builds into the region with the flow aloft becoming more zonal. There could still be some lingering mid to high level clouds to start the day, especially for southern sections of the forecast area, otherwise it should turn out to be mostly sunny. Went on the cooler side of the guidance average for high temperatures, but this still places us near normal for this time of the year. High pressure continues to build in for Saturday night with a mostly clear sky. Conditions are more favorable for radiational cooling versus tonight, and combined with a colder air mass, lows are expected to drop into the teens across parts of the lower hudson valley, interior ct, and the pine barrens region in eastern li. The rest of the tri-state area should have lows in the 20s. Long term Sunday through Friday Upper shortwave moves out of the upper mid west, passing across the great lakes region, then shears out across the northeast Monday. Weak ridge, quasizonal flow then prevails behind this shortwave ahead of western trough that will eventually move across the midwest, weakening as it does so, but amplifying the ridge ahead of it across the eastern states. This trough passes Thursday. At the surface, weak low pressure tracks across the appalachians Sunday night as high pressure to the northeast yields as mid level confluence gives way to aforementioned shortwave. Another low develops just south over the waters, and quickly passes east by Monday. The position of this low remains in question, and this will dictate whether or not light snow or flurries mixes with or changes to light rain along the coast. As the sfc low departs, a lingering sfc trough lags behind as sheared out shortwave moves across the northeast. Feel the bulk of the snow or rain snow mix ends, but some lingering light snow or sprinkles cannot be ruled out Monday. Not sure if moisture depth will be sufficient for production of ice crystals, but feel clouds linger, and chance pops are warranted. Forecast amounts of around one to two inches of snow accumulation, with support from latest ECMWF run lending some support. If a mix does indeed occur near the coast, amounts could be lower. Timing Sunday night. High pressure builds across the great lakes Monday night and Tuesday, then next low approaches from the southwest for Tue night- wed. Based on upper steering flow as mentioned, the southern low likely passes well to the west, then nw. Meanwhile, high pressure settles across northern new england, likely resulting in some cold air damming as another low develops along the mid atlantic. Still a lot of details to iron out here, but snow is possible late Tuesday night Wednesday, then a changeover to a wintry mix to rain would likely occur Wed night-thu before ending. Dry Friday behind the system. |
Temperatures through the period will not vary much. In general, temperatures should remain slightly below normal, but as previous forecast stated, arctic air is not anticipated. Aviation 02z Saturday through Wednesday A cold front moves through the terminals from around 02z west to around 07z east. There may be a few scattered showers, however, no impact to ceilings or visibilities are expected.VFR through the forecast period. S to SW wind around 10 kt with shift to the W with the approach of the cold front, and then to the NW with the cold frontal passage. Winds may be around 310 true for several hours from around 04z to 12z, with occasional gusts up to 20 kt at the nyc metro terminals. During Saturday winds will be more from the nw to N around 10 kt. Outlook for 00z Sunday through Wednesday Saturday night-Sunday Vfr. Sunday night-Monday Chance of snow with MVFR or lower conditions possible. Tuesday Vfr. Wednesday Chance of snow with MVFR or lower conditions possible. Marine Sca remains unchanged on the ocean. The non-ocean waters should see gusts remaining below 25 kt tngt, with gusts dropping blw 25 kt on the ocean by around midnight. Seas will however remain at advisory levels through the night and into Saturday morning. Sub-advisory conditions then prevail Saturday afternoon and night. Winds will be rather tranquil ahead of weak low pressure Sunday- Sunday night. Behind the low, winds shift around to the N NW and should increase late Monday-Monday night. As such, ocean seas build slightly before subsiding as high pressure builds and winds lighten again. Winds should increase ahead of the next low and frontal boundary Wednesday.

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. |
