6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported. 5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive. 5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds. |

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kokx 211650 afdokx area forecast discussion national weather service new york ny 1250 pm edt Mon aug 21 2017 Synopsis High pressure over the region moves offshore today and tonight. A cold front approaches from the west Tuesday and passes through Tuesday night into Wednesday morning. High pressure then builds in thereafter through the end of the week with a much drier and cooler airmass. Near term until 6 pm this evening Forecast still mainly on track with just slight adjustments to temperatures and dewpoints to better match observed trends. Weak quasi-zonal flow aloft with main upper level jet stream well northwest of the region. Surface high remains over the area. Expecting a mainly dry day with just a slight chance of showers and thunderstorms for far western orange county late this afternoon. 850mb temperatures forecast to reach near 15-16 degrees c. Surface temperatures forecast to reach several degrees warmer than yesterday. Mid 80s to near 90 degrees f for much of the region with mostly sunny conditions for most locations. For sky cover, better chances of having some translucent cirrus during the timeframe of the partial solar eclipse, which runs about 120 pm to 400 pm in nyc with a peak at 244 pm, are north of the city. For long island, the city and adjacent areas of ne nj, some cirrus still expected but probably not as much coverage as farther north. Cumulus development is happening along sea breeze boundaries over long island and ct and slowly pushing north. Cumulus development may still occur over other parts of the tri state area, however in almost all cases it should be no more that scattered. The western edge of a cirrus shield should be east of the forks region and SE ct by 200 pm. Another area of translucent cirrus moving through northern pa would appear to shift through primarily north of the city in the t cirrus may however develop and pass through the city and long island during this period as well, especially if any convection pops up to our west. Hrrr indicates this convective potential, but may happen too late to be of much significance. Finally, some cumulus development along sea breezes this afternoon may cause some obstruction within about 10 miles of south-facing coasts. Thinking is that any cumulus would be no more that scattered in nature for most spots that see it. Like previous forecast, a look at the hrrrx conveys a slight decrease during maximum obscuration of Sun during eclipse, so adjusted temperature a degree downward at 19z (3pm local time). There is a low risk of rip currents today, becoming moderate late today at atlantic beaches. |
Short term 6 pm this evening through 6 pm Tuesday Rest of the forecast shows high pressure moving farther offshore and a cold front gradually approaching from the west. Upper levels convey an upper level trough with its upper level low based in ontario approaching the region. Continually more warm and humid conditions are expected. Forecast has warmer temperatures Tuesday, getting hot and humid for quite a few locations. Could see heat indices up to 100 degrees in and around nyc. Precip forecast remains near or below 30 percent for showers and thunderstorms. Not much forcing but increasing instability and possible lee trough forming Tuesday could provide focus for convergence. Models are pretty minimal with forecast rainfall amounts overall tonight through Tuesday. Weak trough evident in lower levels late tonight into early Tuesday will lead to pops more in low end chance for showers and thunderstorms and then expecting much of Tuesday to be dry except for interior locations which will have relatively higher chances for showers and thunderstorms. These locations will be closer to lee trough as well. Long term Tuesday night through Sunday A cold front approaches the region Tuesday night and pushes across the forecast area on Wednesday. Expect cloud cover to increase and showers and thunderstorms to develop and move across the region through this time frame. By Wednesday evening, skies will begin to clear and a much cooler airmass will be arriving. Canadian high pressure builds into the region Thursday through the weekend, providing dry and sunny conditions. Temperatures will remain below normal as highs only reach the 70s to near 80 each day. The dry and cooler conditions are expected to continue into Monday. Aviation 18z Monday through Saturday Vfr through the TAF period as high pressure remains in control. An isolated shower or TSTM possible late day near kswf, and early evening for khpn and the nyc metros. Given earlier upstream activity over western ny, which has died down but should refire this afternoon, have enough confidence to mention vcts at kswf. Sea breezes are in at kbdr kgon, and while direction at most other terminals continues to vary between SW and w. A more s-sw sea breeze should set in this afternoon at kjfk kisp and reach klga late, and kewr kteb could be on the edge of a harbor breeze late as well. Gusts 15-18 kt likely. S-sw winds diminish to less than 10 kt this evening. There is also low potential for development of low clouds fog late tonight with MVFR or lower flight cat, mainly at kjfk kisp kgon.

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. |
