(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kokx 160835 afdokx area forecast discussion national weather service new york ny 435 am edt Wed oct 16 2019 Synopsis A strong frontal system will approach today as a low pressure develops just off the mid atlantic coast. This low will track just off long island tonight and continue northeast Thursday. Meanwhile, high pressure will build to the west and move over the region Friday, remaining through the weekend. Another frontal system affects the region Sunday night through Tuesday. Near term through tonight Today will start out quiet before quickly deteriorating as an amplifying northern stream trough interacts with southern stream energy. This will cause rapid development of low pressure along the mid-atlantic coast. Strong upper dynamics aided by the negatively tilted trough, upper jet exit and entrance regions and thermal forcing will result in the potential for several inches of rainfall as the secondary low develops. Widespread moderate to locally heavy rain will produce a general 1 to 3 inches, with the potential for higher amounts in any convectively enhanced bands. Much of this rain will fall in a 6 to 9 hour period from late afternoon early evening to around midnight. If higher amounts materialize, there could be localized flooding, however the probability remains low with the exception for NE nj where a flash flood watch remains in effect based on 6 hour gridded ffg. Ahead of the low, a period of E SE winds 15 to 20 mph with gusts up to 30 mph are likely. Then as the secondary low deepens, the pressure gradient between the two systems will result in stronger northwest winds developing overnight especially across the coast. After collaboration with neighboring offices, have issued a wind advisory for eastern suffolk county and southern new london beginning tonight just ahead of the low where winds will be strongest. Highs will be in the 60s today and in the upper 40s to 50 degrees tonight. Short term Thursday As the low pulls away into maine on Thursday, strong cyclonic flow and cold pool instability could result in a few showers lingering through the afternoon and a mostly cloudy sky. Strong, gusty winds will prevail on Thursday and it is possible that wind headlines may be needed with later forecasts. Strongest winds will be across the far eastern zones where the best mixing and low level winds will be. High temperatures on Thursday will be in the 50s to around 60. Long term Thursday night through Tuesday High amplitude, and progressive, flow will continue through the extended period. One trough with an embedded closed low will be exiting the east coast Thursday night as a ridge builds across the central united states and well into central canada. This ridge moves through the eastern states, and off the coast, Friday through Saturday night. Meanwhile a series of shortwaves move into the pacific northwest, with a stronger wave digging a trough Saturday night and Sunday. This deep trough will then affect the region from Sunday night into Tuesday. For Thursday, strong and gusty winds will prevail in the cold advection and deep cyclonic flow. Held off on a wind advisory at this time as will be the fourth period, with low confidence as sustained winds and gusts will be near advisory levels. Also, highest winds mostly likely will be across the far eastern zones, southeastern connecticut, into the twin forks of long island. This is were best mixing, and strongest low level winds will be. The gfs had higher winds of 50 to 60 kt 900 to 850 mb, and the ECMWF was in the 45 to 50 kt range. With high pressure over the area Friday night, winds will decouple with nearly clear conditions. This will be ideal radiational cooling and inland areas, especially the lower hudson valley, will see low temperatures in the mid and upper 30s with areas of frost. A warm up begins Saturday and continues into early next week. By Sunday temperatures will be several degrees anomalously above normal. For Sunday through Tuesday went above guidance temperatures. There is some uncertainty with the timing of the next system Sunday night into Tuesday, with the ECMWF developing a wave along the triple point, and the GFS more delayed with only warm advection forcing with a warm front developing. Started to bring in precipitation Sunday night, more in line with the ecmwf. Aviation 09z Wednesday through Sunday ***high impact rain and wind event from late this afternoon into Thursday*** high pressure will build offshore today as intensifying low pressure approaches the west. The low will move across tonight. Clouds will gradually lower and thicken through the day today. Some MVFR CIGS could precede the rain during late morning and early afternoon at the nyc metros, then rain and MVFR ifr conditions should quickly develop after 18z. Rain will be heavy at times. Rain tapers off after 4-6z but MVFR cigs around 3000 ft may remain through the remainder of the taf period. Se winds will increase today, with gusts at or above 30 kt likely by late evening tonight. Direction will vary as the low tracks over and through the area. Winds become westerly behind the system late tonight, and remain so through thu. Outlook for 06z Thursday through Sunday Late tonight Rain tapers off but strong winds continue. Thursday Possible MVFR with showers. W winds g30-40kt. Friday Vfr. NW winds g20-25kt. |
Saturday Vfr. Sunday Vfr. Marine A strong system will approach the waters on Wednesday with a coastal low developing across the waters late in the afternoon early evening. This will bring SCA conditions to the area during the day on Wednesday with SE gusts 25-30 kt. As the low pulls away Wednesday night and Thursday westerly gales will bring gusts up to 40 kt. A gale warning continues Thursday for all waters. Gale force gusts may continue into Thursday evening on the non ocean waters and into late Thursday night on ocean waters. With some uncertainty regarding the diminishing time of the gusts, the gale warning has not been extended at this time. Sca wind gusts continue through Friday once gusts fall below gale levels. Ocean seas are also expected to be below SCA levels by Friday night. Tranquil conditions remain on the waters Friday night into the beginning of next week. Hydrology A significant rainfall of 1-3 inches is likely Wednesday afternoon into Wednesday night, with localized swaths of 2-4 inches possible. The bulk of the rainfall is expected in a 6-9 hr period late Wednesday afternoon through Wednesday evening. Urban, poor drainage, and low lying flooding is expected. There is a low probability of flash flooding along a few of the fast responding small rivers and streams in NE nj and the lower hudson valley if the higher rainfall amounts are realized. Additionally, localized flash flooding will also be an issue for coastal roads if heaviest rain coincides with the Wed night high tides. Tides coastal flooding The SE fetch across the waters will enable for piling of water today into tonight. The winds increase today into tonight and eventually become more westerly late tonight. Highest astronomical tide is this morning. Some isolated minor coastal flooding will be possible across the south shore back bays and western long island sound along the westchester and sw connecticut shorelines. Water levels for minor this morning are about 1.5 to 2 ft above astronomical. High tide cycles are between 9am and 12pm across the south shore back bays and between 12pm and 3pm across the western long island sound. For tonight, astronomical tide is lower. However, the surge will be quite more than this morning so the water levels are expected to be about 2.5 to 3 ft above astronomical, allowing for widespread minor coastal flooding for much of long island shorelines as well as westchester shoreline and SW connecticut shorelines along the western long island sound. Other coastal areas are expected to just touch minor coastal flood benchmarks and will be more isolated. Battery ny expected to stay below minor coastal flood benchmark. High tide cycles tonight run between 9pm to 12am for south shore bays, and 12am to 3am for western LI sound, long island shorelines, and SE connecticut. With gusty westerly and mainly offshore flow on Thursday, for the next high tide cycle for Thursday morning, no coastal flooding is expected.

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. |
