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.. Low pressure will pass to the east today, followed by weak high pressure tonight. A cold front will move through on Thursday. Associated low pressure 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.

SYNOPSIS. Low pressure will pass to the east today, followed by weak high pressure tonight. A cold front will move through on Thursday. Associated low pressure 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 PM THIS EVENING/. Expecting mainly dry conds today, but with plenty of low level moisture trapped beneath an inversion resulting in a partly to mostly cloudy sky today, with the 11Z RAP/HRRR showing only potential for a shower or two across Long Island this afternoon. Some clearing may occur late on a N-NW flow. This will allow temperatures to rise into the upper 50s and lower 60s.
SHORT TERM /6 PM THIS EVENING THROUGH THURSDAY NIGHT/. Weak ridging will result in a quiet night ahead of another system which will impact the region during the day on Thursday. Lows Wednesday night will be in the 40s under a partly to mostly cloudy sky.
On Thursday, a strong shortwave will dive out of the Great Lakes with a surface low tracking out of Canada into the northeast. This low will drag a strong cold front through the area, likely sometime from late morning through the mid afternoon. A strong jet developing just to the south will provide deep-layer shear and strong lift, however instability continues to look marginal at this time. Even with low CAPE, strong dynamics aloft will likely result in a line of showers with embedded thunderstorms moving through in the early afternoon. The biggest threat with these showers and storms would be gusty winds.
Immediately following the frontal passage, the sky will clear and we should mix out. BUFKIT soundings are indicating a period of gusty winds of 30 to 35 mph during the afternoon and into the overnight.
LONG TERM /FRIDAY THROUGH TUESDAY/. 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 via 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 /14Z WEDNESDAY THROUGH SUNDAY/. Low pressure will be east of the terminals by late this morning with weak high pressure to follow.
MVFR ceilings will likely linger into early this afternoon across many of the terminals, and IFR conditions are likely at times through this morning with a rather weak northerly flow. Improvement to VFR is expected this afternoon, however, east of the New York City terminals MVFR conditions likely remain into mid afternoon.
A N-NE wind at 5-10 kt backs to NW in the afternoon before a seabreeze develops at the coastal terminals. S/SE winds tonight at less than 10 kt and increase to 10-15 kt with G20kt by mid to late morning Friday.
Chance of showers by 15Z Friday.

OUTLOOK FOR 12Z THURSDAY THROUGH SUNDAY. Thu. MVFR/IFR in the morning with showers and thunderstorms, becoming VFR in the afternoon. W G30-35 kt in the afternoon. LLWS possible in the morning. Fri. VFR with W winds 20-30kt g35-40kt. Sat-Sun. VFR.
MARINE. Quiet today as low pressure passes east, with only a 2-ft ocean swell at most.
A strong frontal system will then impact the waters on Thursday, preceded by a strengthening S flow that will likely bring at a minimum SCA conditions to the ocean waters by late morning. This will be short-lived though as a strong cold front works across the waters in the afternoon with the potential for westerly gusts to approach gale force.
As low pressure rapidly deepens over northern New England Thursday night, westerly gales will likely develop across all waters and continue into Friday with gusts up to 40 kt.
Winds will gradually diminish Friday night into Saturday with SCA conditions for much of the period. High pressure will build across the waters Saturday 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 strong 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. No hydrologic impacts are expected from the showers impacting the area this morning.
A quarter to a half an inch of rain is expected Thursday, 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. High astronomical tides due to the supermoon and a positive tidal anomaly will be factors for the total water level forecast through Wednesday. Winds will not be strong, about a 10 kt onshore flow or less, so tidal piling and wind forcing will not be too much, limiting the coastal flood potential.
Hazards are as follows:
Tonight through Wednesday: Coastal flood statements across much of the shorelines of NY Harbor, Western Long Island Sound, and South Shore Bays. The total water level will be around 1/2 to 1 foot above astronomical tides, so about 1/2 to 1 foot of surge during times of high tide. Isolated minor coastal flooding will be the result.
Wednesday Night: Coastal flood advisories for the more vulnerable coastal locations across NY Harbor, Western Long Island Sound, South Shore Bays and SW Suffolk NY. The total water level will be 1 to 2 feet above astronomical tides, so about 1 to 2 feet of surge during times of high tide. Widespread minor coastal flooding will be the result. Other nearby locations such as Eastern Union NJ, Eastern Essex NJ, Manhattan, Bronx, Northern Queens will get close to touching minor coastal flood benchmarks. These less exposed coastal locations have a coastal flood statement for Wednesday night, more of an isolated minor coastal flood situation.
Minor coastal flooding potential remains on Thursday with astronomical tides still being high. There will also be a strong cold front approaching that will bring increased onshore winds during the day. Much lower total water levels occur Thursday night into Friday as winds strengthen out of the west, a stronger offshore flow overall. Any lingering coastal flood threat diminishes rapidly Thursday night.
EQUIPMENT. NYC NOAA Weather Radio Station KWO35 (162.55 MHz) is undergoing its final stages of testing, and is operating at full power.
