Marine Weather and Tides
Version 3.4 |
12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed. 10/9/2019 Updated the Marine Zones. 9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. |

Synopsis for the long island waters and new york harbor.. A warm front approaches tonight along with an area of low pressure. The low passes through late tonight and exits east Wednesday. A cold front then passes through on Thursday. An associated low will pull away into the canadian maritimes on Friday, followed by high pressure building from the west on Saturday. Low pressure will then approach from the west on Sunday and impact the area Sunday night into Monday.

Area Forecast Discussion National Weather Service New York NY 346 PM EDT Tue Apr 7 2020
SYNOPSIS. A warm front approaches tonight along with an area of low pressure. The low passes through late tonight and exits east Wednesday. A cold front then passes through on Thursday. An associated low will pull away into the Canadian Maritimes on Friday, followed by high pressure building from the west on Saturday. Low pressure will then approach from the west on Sunday and impact the area Sunday night into Monday.
NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/. A warm front will approach from the SW tonight. At the same time, low pressure across the Great Lakes will track along the approaching warm front. Models remain in fairly good agreement with timing of the arrival of rain ahead of the front. Chances of rain begin west of the Hudson this evening, then rain eventually becomes likely west to east overnight. Will leave in a low chance of thunder for parts of the forecast area as models show some elevated instability and enough low-mid level lift.
SHORT TERM /6 AM WEDNESDAY MORNING THROUGH THURSDAY NIGHT/. A weak north to northeast flow occurs behind the departure of low pressure Wednesday morning. Plenty of moisture remains beneath 800mb, so clouds won't have much of any chance to scour out. Even after rain chances drop off early in the morning, cannot rule out a chance of an afternoon. This chance will be focused more towards the western zones during the afternoon where models depict convergence along a surface trough just off to our west. Prefer the cooler guidance for high temperatures given the anticipated cloud cover and NE low level flow in the afternoon. Dry weather should then follow for Wednesday night.
A cold front approaches on Thursday and passes through late in the morning/earlier portion of the afternoon. Models in good agreement with rain/showers with this cold front. Shear will be strong and synoptic lift will be deep with the core of a jet streak eventually passing not too far to our south. How much CAPE we actually get ahead of the cold front is questionable as an onshore flow and low level moisture probably starts us off with mostly cloudy conditions. Even with low CAPE, strong lift and shear probably results in a line of showers with embedded thunderstorms moving through. Biggest threat with these showers would be strong wind gusts. Breezy and dry behind the front late in the day into Thursday night. Just a slight chance of mixed rain/snow showers well NW of the city late at night.
LONG TERM /FRIDAY THROUGH TUESDAY/. Reasoning from previous forecasts remains relatively similar, with some changes based on latest guidance that were hinted at yesterday. To start, expect brisk conds on Fri, with isold-sct showers as low pressure pulls away. Inland sections especially the higher elevations could see some snow mixed in during the morning. W-NW winds will be on the brisk side due to the departing low's tight pres gradient, so expect winds at or near advy criteria in the greater NYC metro area and across Long Island, and possibly elsewhere.
High pressure then builds across Sat into Sat night. Guidance shows more nrn stream interaction with a srn stream low pressure system approaching for Sunday into Mon, and so have gone with its slower trend. That guidance is also decidedly wetter and windier, which makes sense given the strengthening offshore high and long S fetch, at least per ECMWF. GFS fcsts a secondary low to develop along the coast which, if it develops, would probably result in a stout E-SE rather than S flow. Given the very good warmth/moisture transport via either a S fetch or enhanced convergence/lift va a secondary low, heavy rain also looks like a good bet, with axis of heaviest rain a little to early to know for certain.
Temps about 5-8 deg below normal on Fri, with highs in the lower/mid 50s, will moderate somewhat on Sat to mid/upper 50s, still slightly below avg. Temps on Sunday/Mon ahead of the approaching low should warm up, with upper 50s to mid 60s on Sunday, and 60s to lower 70s on Mon, highest away from the coast.
AVIATION /20Z TUESDAY THROUGH SUNDAY/. A frontal sys passes late tngt into Wed mrng.
VFR thru at least 3Z, then -ra develops with MVFR likely. There is a low chc of IFR cigs 6-12Z. Mainly MVFR is expected to linger on Wed. The best chc for breaks to VFR will be aft 16Z.
Sea breeze flow will continue to develop this aftn. Amendments can be expected for timing. Winds decrease tngt, then aft the fropa, NW flow veers gradually to the E on Wed. Speeds generally aob 10 kt.
OUTLOOK FOR 18Z WEDNESDAY THROUGH SUNDAY. Rest of Wed. Mainly MVFR. Thu. MVFR in the mrng, becoming VFR. LLWS possible in the mrng. Fri. VFR with W winds 25-35kt. Sat-Sun. VFR.
MARINE. Sub-SCA conditions are expected to remain on all waters through Wednesday night.
A cold front will approach the waters on Thursday increasing wind gusts to SCA levels on all waters. Ocean seas will also build, reaching 6-7 feet Thursday night and up to 10 feet on Friday.
W-NW gales may be possible on Friday, especially near shore and also on the outer ocean waters. SCA conds in all waters Fri evening should take some time to diminish, with quiet conds not returning til late day Sat or Sat night.
Increasing S flow between a strengthening offshore high and approaching low pressure may bring SCA conds to all waters Sunday night. Some gale force wind gusts may be possible on the ocean waters late.
FIRE WEATHER. Wetting rains on Thu should help limit fire growth potential on Fri despite string winds and low afternoon RH. With some drying out Sat could be a day of concern, with W winds still gusting to 30 mph and min RH 20-30%.
HYDROLOGY. Just a quarter to half inch of rainfall expected late tonight through Wednesday morning. Same amounts for Thursday's system, but locally higher amounts could be realized. Low chance of minor nuisance flooding on Thursday.
QPF for the low pressure system Sunday night into Mon has trended wetter, with amts of 1-2 inches fcst. This may be capable of causing some minor areal and small stream issues.
TIDES/COASTAL FLOODING. A coastal flood statement remains for tonight's high tide has for Lower New York Harbor, south shore back bays of western Long Island, and for locations adjacent to western Long Island Sound. The coastal flood statement has also been extended through Wednesday morning/early afternoon high tide for the same locations except locations adjacent to western Long Island Sound in northern Nassau and northwest Suffolk. Additional statements and/or advisories are likely through Wednesday night.
Astronomical tides will be increasing through Wednesday due to a full moon (supermoon). There could be a few locations that get close tonight into Wednesday morning/early afternoon. Much of the guidance continues to point toward Wednesday night having the greatest potential for widespread minor and even localized moderate flooding.
Most locations during this time need anywhere from 1/2 to 1 1/2 ft of surge to reach minor coastal flood benchmarks. During this time, there is little in the way of wind forcing or tidal piling. The main factor will be the high astronomical tides and background positive tidal anomaly.
Minor coastal flooding is also possible on Thursday as astronomical tides remain high. There will also be a strong cold front passage that may bring a bit stronger wind forcing.
EQUIPMENT. NYC NOAA Weather Radio Station KWO35 (162.55 MHz) is undergoing its final stages of testing, and is operating at full power.
