NOTICE 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. 6/2/2019. Many thanks to a user for reporting an error on one of the Edit pages. The switch to PHP 7.2 caused many pages that previously worked to quit working.

Area Forecast Discussion National Weather Service New York NY 1242 AM EST Sun Dec 8 2019

SYNOPSIS. High pressure will settle over the area tonight, then pass east on Sunday. A warm front will approach on Monday and lift north Monday night. A cold front will approach on Tuesday and pass east Tuesday night into Wednesday. Arctic high pressure will then follow later in the week. Another storm system may impact the area next weekend.

NEAR TERM /UNTIL 6 AM THIS MORNING/. High pressure settles across the are overnight, This will result favorable conditions for strong radiational cooling. Lows by morning will fall well down into the lower teens across the interior, particularly where snowpack lingers, as well as the pine barrens region of LI. Otherwise, lows generally in the upper teens to lower 20s coast, mid 20's city.

SHORT TERM /6 AM THIS MORNING THROUGH 6 PM MONDAY/. Weak shortwave ridging moves over and east of the region Sunday, with deep SW flow developing Sunday Night into Monday ahead of a developing large central CONUS trough.

At the surface, high pressure slides offshore Sunday, with developing return flow Sunday Night. Another dry day on Sunday, with increasing high clouds filtering in with SW aloft flow. Highs generally upper 30s to lower 40s, but still a few degrees below seasonable.

Thickening and lowering high and mid clouds Sunday Night and increasing SSE flow. Potential for stratus and light shower activity developing overnight into early Monday morning. Temps remain fairly stable or rise along the coast Sunday night in response.

Developing low pressure across the Central Plains Sunday Night, will lift NE into the Great Lakes Monday. Meanwhile a weak wave of low pressure off the SE US coast, lifts north up the coast in between departing high and approaching frontal system. This feature then moves over or just SE of LI on Monday. Deep layered lift (left front of 150+ kt ulj and nose of developing 50-60kt llj) and convergence of a sub-tropical PAC and Atlantic moisture feed (+2-3 std PWATs and elevated weak instability) will present potential for period of moderate to heavy rain, with embedded thunder, Monday morning into afternoon. Some spread in exact track of the wave, lending to uncertainty in how far west this heavy activity gets, with highest likelihood across LI and CT. A swath of 1/2 to 1 inches of rain possible in 6 hr period with this activity. In addition, potential for 20 to 30 mph sustained and gusts to 40 mph for LI and SE CT Monday afternoon if LLJ tracks overhead.

This wave and its trailing trough, with axis of heavy rain, move east Monday evening, but still bands of shower activity expected to linger into Tuesday Night ahead of next shortwave and pre- frontal trough.

LONG TERM /MONDAY NIGHT THROUGH SATURDAY/. With digging large upper trough, passing shortwave, upper and lower jet energy aiding lift, rain initially will be heavy, then taper off to light rain, and even scatter as coverage lowers late at night into Tuesday morning. The area will be warm sectored during that time, and lowering of Pops has been captured in database. Will ramp up Pops once again as the cold front approaches Tuesday afternoon. Looks like the GFS is a quicker outlier with frontal movement east.

As another shortwave rotates around the back side of the upper trough in central Canada, there are indications that rain moves just east, with additional rain/precip shield tracking northeast on the back side of the front Tuesday night into Wednesday due to upper level support. Assuming that does indeed occur, colder air will move in behind the front which will result in a transition from rain to snow, mix in between. This could result in light snow accumulations later Tuesday night into Wednesday, NW to SE.

The upper trough weakens as it pivots east, and sfc high pressure builds in from the west late Wed, Wed night and Thursday. This will be the period of dry, but cold weather. Could be looking at the coldest air of the season, with temps struggling to reach or exceed freezing Thursday after a cold start to the day.

Shortwave ridging moves east Thu night, with sfc high moving north and east of the area. Easterly flow then sets up, with dry conditions likely lingering into Friday. Thereafter, model spread grows, with latest run of the operational GFS quicker with southern shortwave's movement east, which steers a sfc low out of the Gulf of Mexico and off the SE coast later Friday and Friday night, whereas Canadian and ECMWF are much slower with these features. Eventually, precip should move back in from the south by Saturday, but big difference in the upper level pattern are noted in the global models, with GFS phased with northern stream shortwave and southern stream. Canadian and ECMWF look much different (lack of phasing between the two), so plenty of time to iron out these details as the event draws near.

Mild temperatures Monday night into Tuesday, well above normal, fall below normal Wednesday night through Thursday night. Temps will moderate late in the week, and a model blend followed which is close to WPC numbers.

AVIATION /06Z SUNDAY THROUGH THURSDAY/. VFR. High pressure settles over the terminals overnight, then passes offshore in the afternoon.

Light northerly to variable winds overnight becomes S-SE by late morning and increase to around 10 kt with gusts 15-20kt by early afternoon.

MVFR conditions begin late in the TAF period with lowered ceilings entering the region ahead of potential showers.

OUTLOOK FOR 06Z MONDAY THROUGH THURSDAY. Sunday night. MVFR developing late with chance of rain. Monday. Rain becoming widespread. S G20-25kt, mainly at the coastal terminals, with a chance of LLWS Monday into Monday night. Slight chance thunder Monday afternoon. Tuesday. MVFR or lower in showers, possibly ending as a period of snow late at night. SW gusts around 20 kt possible. Wednesday. Chance of rain or snow and MVFR in the morning. W-NW G20-25kt possible. Thursday. VFR.

MARINE. Sub SCA conditions tonight through Sunday as high pressure moves across the waters. A strengthening southerly flow may bring marginal SCA conditions to the ocean waters Sunday night, with higher likelihood for a period of SCA for all waters Monday afternoon/evening, and potentially a period of gales for ocean waters and eastern LI Sound and bays. Seas should build to 8 to 12 ft by late Monday as well.

Southerly winds will approach gale force Monday night over the ocean waters, with solid SCA conditions elsewhere. These winds diminish as a cold front approaches Tuesday. The winds shift to the west/NW behind the front Tuesday night and Wednesday, remaining gusty through Thursday as high pressure approaches from the west.

Rough seas will slowly subside through the mid week period.

HYDROLOGY. A significant long duration rainfall event is expected from late Sunday night into Wed. Event total QPF likely to range from 1.5-3.0 inches.

Heaviest rain will be Monday into Monday night, with 1 to 2 inches of rain likely during this period. The long duration of the event should preclude widespread flooding. Nuisance/poor drainage flooding is the most likely outcome.

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