Marine Weather and Tides
Version 3.4 |
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues. |

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kokx 240239 afdokx area forecast discussion national weather service new york ny 1039 pm edt Sat jun 23 2018 Synopsis A warm front will remain to the south tonight while a wave of low pressure moves along it. The front will then lift to the north on Sunday, followed by a cold frontal passage Sunday afternoon and evening. High pressure will then build in through mid-week, giving way to a warm front Wednesday night. A weak cold front will then approach on Thursday and possibly dissipate over the region Friday into Saturday. Near term until 6 am Sunday morning A warm front remains to the south of the region, and a shortwave will be shifting through overnight, and this may result in a shower or two in spots. The warm front is expected to lift towards long island overnight with diminishing chances of showers and drizzle. There is some elevated instability, however this remains mainly to our south. Perhaps some thunderstorms pass within 40-50 miles south of eastern long island tonight. Have also added some fog to the forecast. Dense fog cannot be completely ruled out ahead of this warm front, so this will need to be watched. Temperatures should remain nearly steady this evening, and rise a couple degrees overnight in some areas. Short term 6 am Sunday morning through Sunday night On Sunday, the warm front should lift north, followed by SW to wsw flow that will slowly steer a cold front through late in the day and at night. Moderate instability builds NW of nyc, and showers and thunderstorms should redevelop during the afternoon, move east toward nyc metro, long island, and southern ct from late day into early evening, then dissipate overnight. Given the combo of instability and 35-40 kt unidirectional westerly deep layer shear, storms could produce gusty winds, perhaps an isolated damaging wind gust. Lows tonight will remain in the 60s, and warmer temps are anticipated Sunday as area sits temporarily in the warm sector. Upper 80s expected for urban NE nj, and lower mid 80s elsewhere. Lows again fall into the 60s Sunday night. There will be a moderate rip current risk at the ocean beaches. Long term Monday through Saturday High pressure builds in during Monday, but with a cyclonic flow aloft coinciding with lift from a surface trough and shortwave, there could be a shower or two across SE ct and eastern li. Partly cloudy otherwise with near normal temperatures. The high pressure center moves through on Tuesday with sunny conditions and highs slightly cooler, but still close to normal. The high will be to our east on Wednesday, and a return SW flow will bring warmer and more humid conditions. It appears the daytime hours for most areas will be dry as showers ahead of an approaching warm front remain to the west. The warm front moves through, then a cold front slowly approaches Thursday into Friday. A surface trough likely forms over the area ahead of the cold front. It's beginning to look more likely that the front never makes it through the entire region and instead dissipates nearby sometime Friday into Saturday. Will maintain slight chance to chance pops Wednesday night through Friday, then go with a dry forecast thereafter. Rising temperatures aloft will allow for highs around 90 in the city and some inland areas Thursday. 90s then become more widespread across the tri-state area for Friday and Saturday. A south to southwest flow along with sufficiently high dewpoints through the top of the mixed layer would limit the magnitude of surface dewpoints mixing-out each afternoon. Heat advisory criteria could therefore be met in this period, particularly Friday and Saturday. Aviation 03z Sunday through Thursday High pressure to the north moves through the canadian maritime |
into Sunday as waves of low pressure move along a nearly stationary front south of long island overnight. The front will begin to move toward the terminals late. A cold front approaches from the northwest Sunday afternoon and moves through the terminals Sunday evening. MVFR to ifr conditions are expected to become widespread ifr across the region soon after midnight. Periods of lifr, and locally vlifr, are possible outside of the city terminals overnight. Conditions slowly improve Sunday morning, becoming vfr by afternoon. Drizzle and brief light rain will be possible this evening. Then with the approach of the cold front showers will be possible late in the afternoon and into the evening. There is also a chance of thunderstorms mainly to the west and north of nyc metro terminals. Winds will be light and variable overnight then become SW to s in the morning. Sea breezes are possible, however, confidence is low. Outlook for 00z Monday through Thursday Sunday night Vfr with MVFR to possibly ifr, in showers and isolated thunderstorms early in the evening. Best chance for any thunderstorms will be to the N W of nyc. Monday-Wednesday Vfr. Nw-n winds g15-25kt Monday-Monday night. S-sw winds g20-25kt possible Wednesday. Wednesday night-Thursday MVFR or lower probable. Showers are also probable and there is a chance of thunderstorms as well. Sw winds g15-25kt possible. Marine Winds and seas forecast on track with no changes at this time. An approaching warm front will allow for a weak flow overnight with a subsequent decrease in seas. Ocean seas could however briefly climb to around 5 ft daytime Sunday with a building southerly swell. Conditions will remain tranquil through Tuesday with building high pressure. Thereafter, the high shifts offshore with a s-sw strengthening and sca-level gusts possible on all waters Wednesday afternoon through Thursday evening. Ocean seas will increase to sca-levels in response to the strengthening and prolonged south-southwest flow. Hydrology There could be a few locally heavy downpours Sunday afternoon and evening. However, no hydrologic impacts are anticipated. Areal average rainfall totals through Sunday evening will be under 1 2 inch, but heavier storms on Sunday could still produce locally up to an inch. No hydrologic impacts are expected from Monday through the rest of the forecast period.

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. |
