Area Forecast Discussion National Weather Service New York NY 734 AM EST Thu Dec 12 2019

SYNOPSIS. Dense arctic high pressure system shifts over the Tri-State area today then continues to move east and offshore tonight. Low pressure approaches from the south Friday and passes through on Saturday with high pressure building back in Sunday and Monday. Another storm then impacts the area for Tuesday.

NEAR TERM /THROUGH TONIGHT/. Forecast on track with just minor adjustments to reflect latest observations. Otherwise, a strong 1040mb high pressure system builds over the Tri-State area this morning through the evening spurred eastward by a 120kt zonal jet streak over Maine. This system brings in much drier conditions than the previous 24 hours with an average 1000-500mb RH fall to less than 20%. As a result clear skies expected with no chance of precipitation.

Temperatures will be much colder as well approximately 10 degrees lower than the daily normals. High temperatures in the afternoon will struggle to reach the mid 30s near the city and across Long Island. Areas around the Lower Hudson Valley and Southern CT may not rise about freezing despite the sunny day.

SHORT TERM /FRIDAY/. High pressure shifts offshore Thursday evening and overnight as locally winds become more southerly allowing for moisture in the low levels to begin to return to the region. In the upper levels of the atmosphere a trough axis over the Lower Mississippi Valley promotes a southwest to northeast upper level flow. In this flow regime deep sub-tropical air will be able to moisten the environment locally.

Expected an chance for scattered showers Friday afternoon into the evening as cloudiness increases throughout the day though isolated showers could be possible in the late morning hours as well. Temperatures return to near normal reaching the mid 40s by the afternoon.

LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/. The long term period starts off wet as an area of low pressure impacts the region Friday night through Saturday night. POPs will gradually increase Friday night with rain rain becoming likely.

The center of the storm is expected to pass over or nearby the Tri- State Area Saturday morning into the early afternoon. Increasing lift with deep moisture brings primarily rainfall that will be moderate, to locally heavy at times. Rain chances gradually drop off through Saturday night with the storm off to the east and a westerly flow developing in its wake. There may be a few left over showers early Sunday morning, but overall, drier weather is expected on Sunday.

High passes over the area on Monday, with dry weather continuing. The next low pressure system then approaches from the Ohio Valley Monday night with increasing chances of rain, snow, or a rain/snow mix into Tuesday. Will continue to keep PoPs limited to no higher than 50% through Tuesday night as 00z forecast models continue to show different storm tracks. The exact track will have implications on precipitation type. Went with the middle ground for this forecast, including simplified PCPN types this far out in time, however, it is possible we could see some sleet or even some freezing rain depending on the exact track of the low, and at this point, its too far out to determine that now. High pressure would then follow for Wednesday with dry weather.

AVIATION /13Z THURSDAY THROUGH MONDAY/. High pressure builds over the region today and then moves offshore through tonight.

VFR though most of the period with MVFR ceilings developing after 06Z Friday.

NW winds will continue to gradually lighten through the morning hours. Any lingering gusts should end by 10z. A weak and variable flow should occur 18z-21z before a weak S-SE flow develops late in the afternoon into the early evening.

Detailed information, including hourly TAF wind component forecasts, can be found at: http:/www.weather.gov/zny/n90

KJFK TAF Comments: Winds could vary 20-30 degrees to the right of forecast this morning.

The afternoon KJFK haze potential forecast is GREEN . which implies slant range visibility 7SM or greater outside of cloud.

KLGA TAF Comments: Winds could vary 20-30 degrees to the right of forecast this morning.

The afternoon KLGA haze potential forecast is GREEN . which implies slant range visibility 7SM or greater outside of cloud.

KEWR TAF Comments: Winds could vary 20-30 degrees to the right of forecast this morning.

The afternoon KEWR haze potential forecast is GREEN . which implies slant range visibility 7SM or greater outside of cloud.

KTEB TAF Comments: Winds could be light and variable through the evening.

KHPN TAF Comments: No unscheduled amendments expected.

KISP TAF Comments: Winds could vary 20-30 degrees to the right of forecast this morning, but speeds under 10 kt.

OUTLOOK FOR 12Z FRIDAY THROUGH MONDAY. Friday and Friday night. MVFR or lower. Rain developing, especially Friday night. Saturday. IFR in rain, tapering off to scattered showers later in the day and at night. LLWS possible. Sunday. Generally VFR. West winds 10-15kt gusts 20-30kt. Sunday night-Monday. VFR.

MARINE. Wave heights diminish during the day Thursday with offshore waters 2-3 feet. South winds strengthen Friday and waves increase through the day reaching 4-5 feet by the late afternoon.

Winds and seas continue to increase Friday night ahead of low pressure, which is expected to pass through or nearby during Saturday morning or early afternoon. SCA conditions area expected on the ocean waters Friday night through Saturday. For the non-ocean waters, there is a chance we remain sub-sca as gusts do not reach 25 kt and seas do not reach 5 ft. The exact track of the low will determine whether or not sca conditions are met.

Winds then pick up from the west on Saturday night and Sunday behind the storm. SCA conds likely for all waters, and potentially gales Sunday into Sunday night on the ocean, eastern LI Sound and the eastern LI bays. Winds and seas subside on Monday with the approach of a high pressure ridge, but possibly still within advisory criteria for a portion of the day.

HYDROLOGY. 1.00 to 1.50 inches of rainfall with locally higher amounts are anticipated from Friday night through Saturday. Minor nuisance flooding will be possible with this event.

TIDES/COASTAL FLOODING. There will be a chance of coastal flooding with the high tide cycle during Saturday morning. This will be due to onshore winds with an approaching storm combined with relatively high astronomical tides due to a nearly full moon. Minor coastal flooding will be possible primarily along the south shore back bays of Long Island, where even moderate coastal flooding is a possibility at least along the Nassau County bays. Minor flooding will also be possible along NY Harbor and parts of Western Long Island Sound. Confidence is not high at this point as the event is still a few days away, and shifts in storm's track and/or timing would change the flooding potential.

EQUIPMENT. NYC NOAA Weather Radio Station KWO35 (162.55 MHz) is still operating at reduced power.

OKX WATCHES/WARNINGS/ADVISORIES. CT . None. NY . None. NJ . None. MARINE . Small Craft Advisory until 10 AM EST this morning for ANZ350.
