Area Forecast Discussion National Weather Service New York NY 1200 PM 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/. Strong high pressure building over the region will lead to a sunny and cold day. Only minor adjustments made to the forecast to reflect the latest observations.

Temperatures will be approximately 10 degrees lower than the daily normals.

SHORT TERM /FRIDAY/. High pressure shifts offshore this evening and overnight as 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 /18Z THURSDAY THROUGH TUESDAY/. High pressure builds over the region this afternoon and then moves offshore tonight into Friday.

VFR though most of the TAF period with MVFR ceilings developing on Friday with chances of rain increasing during the day.

N-NNW winds 5-10 kt become light and variable mid to late this afternoon, eventually becoming more E-SE tonight into Friday around 5 kts.

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

KJFK TAF Comments: Low confidence on wind direction mid to late this afternoon. Winds go from north flow to more east to southeast flow.

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

KLGA TAF Comments: Low confidence on wind direction mid to late this afternoon. Winds go from north flow to more east to southeast flow.

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

KEWR TAF Comments: Low confidence on wind direction mid to late this afternoon. Winds go from north flow to more east to southeast flow.

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

KTEB TAF Comments: Low confidence on wind direction mid to late this afternoon. Winds go from north flow to more east to southeast flow.

KHPN TAF Comments: Low confidence on wind direction mid to late this afternoon. Winds go from north flow to more east to southeast flow.

KISP TAF Comments: Low confidence on wind direction mid to late this afternoon. Winds go from north flow to more east to southeast flow.

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 will continue to diminish 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.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
