Area Forecast Discussion National Weather Service New York NY 722 PM EST Wed Dec 11 2019

SYNOPSIS. Strong arctic high pressure builds in through tonight, then pushes offshore Thursday afternoon. Low pressure approaches from the south Friday and passes through on Saturday with high pressure building back in on Sunday and Monday. Another storm then impacts the area for Tuesday.

NEAR TERM /UNTIL 6 AM THURSDAY MORNING/. Minor updates were made mainly for hourly temperatures, dewpoints and cloud cover based on latest obs and trends. Rest of the forecast is on track.

Strengthening arctic high pressure (1040+ mb by early Thursday morning) builds in tonight. Subsidence underneath the high will allow for a mostly clear sky. With the high strengthening, the pressure gradient increases, allow for winds to increase. So, although tonight will not be an optimal night for radiational cooling due to the winds, it should be rather cold due to cold advection, clear skies, and snow pack. Temperatures will drop to the teens in the outlying areas, and the middle 20s for the New York City metro area. Lower to middle 20s are expected elsewhere. Combined with the winds, it will feel more like the teens and single digits across the forecast area late tonight into early Thursday morning.

SHORT TERM /6 AM THURSDAY MORNING THROUGH THURSDAY NIGHT/. Dry conditions continue into Thursday and Thursday night as the center of the high quickly moves over the area, then offshore thanks to zonal flow aloft. Continued cold advection early Thursday will mean well below normal high temperatures. Highs will be in the lower to middle 30s, some 10 to 15 degrees below normal for this time of year.

Return flow sets up on the back side of the high as it pushes offshore late Thursday. This will allow a warm front to lift well north of the area. Thursday night will see a non-diurnal temperature trend, with temperatures remaining steady or rising through the night, especially along the coast. Lows in the 20s to lower 30s will be reached early in the night. The return flow will also mean an increase in moisture aloft and therefore an increase in clouds.

LONG TERM /FRIDAY THROUGH WEDNESDAY/. Low pressure begins to take shape across the Southeast with high pressure centered well off to our northeast. Isentropic lift ahead of a warm front interacts with fairly shallow moisture for a chance of light rain or drizzle Friday morning, which could be freezing for a brief time NW of the city. Better chances of rainfall then occur in the afternoon as moisture deepens. Rain eventually becomes likely across the forecast area as Friday night progresses.

The center of the storm is expected to pass over or nearby the Tri-State Area Saturday morning into early afternoon. Increasing lift with deep moisture brings primarily rainfall that will be mainly moderate, but may be heavy at times. Rain chances drop off through Saturday night with the storm off to the east and a westerly flow developing in its wake. This will lead to a dry and breezy Sunday with high temperatures a few degrees above normal.

A high pressure ridge shifts through on Monday, keeping us dry. Another low pressure system then approaches from the Ohio Valley Monday night with increasing chances of rain or mixed PCPN into Tuesday. Will limit PoPs to no higher than 50% through Tuesday night as global deterministic models and ensembles disagree with the track of the storm. The track will also have implications on PCPN type. Went with the middle ground for this forecast, including simplified PCPN types this far out in time. High pressure would then follow for Wednesday with dry weather.

AVIATION /00Z THURSDAY THROUGH MONDAY/. High pressure builds toward the region tonight, and passes overhead Thursday.

VFR. W winds will gradually veer through the night with gusts 20-25 kt for the first half of the night. The gusts could initially be more occasional, but should become more frequent around the 03Z timeframe. NW winds lighten late tonight into Thursday morning. A weak S-SE flow develops late in the afternoon into the early evening.

OUTLOOK FOR 00Z FRIDAY THROUGH MONDAY. Thursday night. Becoming MVFR after 06Z. Friday and Friday night. MVFR or lower in developing rain, 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. SCA in effect as winds increase across all waters tonight, thanks to increasing pressure gradient from a strengthening high building into the area from the west. 25 to 30 kt gusts are expected through about midnight tonight, but will diminish thereafter.

Waves build to 4 to 6 ft on the ocean waters and will also diminish overnight, with the eastern ocean zone hanging on to 5 ft waves for a few hours Thursday morning. SCA in effect through much of Thursday morning for eastern ocean zone because of this.

Winds and seas increase Friday and Friday night ahead of low pressure, which is expected to pass through or nearby during Saturday morning or early afternoon. SCA conds will be possible on the ocean by the end of the day Friday, eventually become probable Friday night and remain likely throughout Saturday. For the remaining waters, there is a chance that gusts do not reach 25 kt up to this point. Models disagree with the track of the center of the storm and how potent it will be, but best chances of gusts this high would be late Friday night/early Saturday morning should they occur.

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. No hydrologic issues are expected with mainly snow this Friday.

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 6 AM EST Thursday for ANZ330-335- 338-340-345-353-355. Small Craft Advisory until 10 AM EST Thursday for ANZ350.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
