Area Forecast Discussion National Weather Service New York NY 406 PM EST Mon Feb 17 2020

SYNOPSIS. A cold front will pass through early, then high pressure will build across New England tonight. A warm front will lift northward toward the area Tuesday morning and move into the area Tuesday afternoon, followed by a cold frontal passage Tuesday night. A large high pressure system will then slowly build from the west mid to late week. Low pressure could impact the area early next week.

NEAR TERM /UNTIL 6 AM TUESDAY MORNING/. Sfc analysis shows a weak cold front dropping through the area attm, as high pressure in its wake builds from srn Ontario/Quebec into New England. As the high drifts E and low pressure over the nation's mid section approaches, high and then mid clouds will lower and thicken. Low temps will range from the mid 20s well inland to the mid 30s in NYC, and with the advancing cloud cover and E flow becoming established overnight, those lows could be reached by midnight, with temps remaining steady or slowly rising overnight.

SHORT TERM /6 AM TUESDAY MORNING THROUGH TUESDAY NIGHT/. As a warm front approaches, mainly light precip should overspread the area Tue morning and continue into the evening. Temps appear cold enough at the onset for a little light snow across the interior mainly north of I-287 in NJ/NY and I-95 in CT, mainly just a coating, perhaps as much as an inch in the highest elevations of Orange County. It is possible that some interior sections across the far northern tier could see a brief transitional period of freezing rain if any in-situ cold air damming develops with the onset of precip and shuts off WAA SE flow for a while as warmer air arrives aloft--confidence in this is low, and areal coverage too limited to warrant an advisory attm.

Rain will continue into the afternoon and evening as the warm front lifts into the area, and temps across NYC metro, Long Island, and SE are likely to reach 50 as they briefly get into the warm sector late afternoon and into the evening before cold fropa.

Precip gradually winds down and winds shift NW after cold fropa, with low temps ranging from from the mid 30s well inland, to lower 40s NYC and Long Island.

LONG TERM /WEDNESDAY THROUGH MONDAY/. Upper northern stream trough will move slowly southeast passing over the northeastern portion of the country Thursday night. Sprawling high pressure from the western United States across the mid section of the country Wednesday will make slow eastward progress. CAA will be underway beginning Wednesday behind the cold front, and strong subsidence thanks to confluent flow aloft will allow for plenty of sunshine by afternoon.

A few more clouds move in ahead of the upper trough Wednesday night and Thursday, but dry weather persists, along with cold temperatures about 10 degrees below normal Thursday and Friday.

For the weekend, northern stream trough departs to the east, with southern stream shortwave passing well south, and zonal flow over much of the northern states. As the sfc high builds to the south, cold northerly flow backs to the W/SW, and WAA ensues. Temperatures under plenty of sunshine Saturday rebound close to if not slightly above normal.

A few clouds increase later Sunday as next shortwave moves out of the western states, and across the mid section of the country Sunday night and Monday. Another northern stream shortwave also passes well north.

At the sfc, a cold front approaches Sunday night, with main low tracking across the Ohio Valley. Some moisture may get pulled northward along the northern stream system, and cold front which could result i a spot shower. However, the best chance for rain likely holds off until later Monday as the low and warm front draw closer.

AVIATION /21Z MONDAY THROUGH SATURDAY/. High pressure builds overhead through this evening with mostly clear skies and only some intervals of high level clouds expected.

VFR through 12z Tuesday. However MVFR conditions with light rain begin later Tuesday morning as a system nears the forecast area from the west. KSWF may begin as a brief period of light snow before quickly changing to rain by the early afternoon. A period of IFR conditions then becomes increasingly likely after 18z Tuesday. A brief period of LLWS is possible from 18z to 22z Tuesday for city terminals, with confidence of occurrence low at this time.

Light winds around 5-10 kt will continue through this evening. Localized light seas breezes likely for KJFK, KISP, KBDR, KGON with amendments possible through the early evening. Overall the winds gradually shift to the NE late this evening. Southeast winds 10-15 kt develop Tuesday morning. Winds will then become more southerly during Tuesday afternoon.

OUTLOOK FOR 12Z TUESDAY THROUGH SATURDAY. Tuesday. MVFR, then IFR becoming increasingly likely in rain during the afternoon. A period of light snow can not be ruled out across interior for the late AM before quickly changing to rain. SE- S winds G15-20kt. Tuesday night. MVFR or lower in light rain in the evening, then VFR. Winds becoming W-NW G15-20kt, mainly along the coast. Wednesday. VFR. NW winds G15-20kt. Thursday-Saturday. VFR.

MARINE. Sub SCA conditions expected across all waters through most of tonight. E flow ramps up fairly quickly overnight, with SCA conds expected on the ocean waters before daybreak, then on the eastern Sound and the bays of Long Island, as SE flow increases to 20-25 kt with gusts 25-30 kt. Winds may peak briefly at 35 kt just before a low level inversion develops late Tue morning or early Tue afternoon. A warm front moving into the waters Tue afternoon should bring an end to SCA conds on all but the ocean waters, where hazardous seas 4-7 ft will still be ongoing.

Winds shift NW after cold fropa Tue night, with lingering 5-ft ocean seas slowly subsiding into Wed night. The gusty NW flow could come close to 25 kt attm late Tue night into Wednesday, but overall, sub-SCA conditions will likely persist as a large area of high pressure builds from the mid section of the country, passing south by Saturday. Since the center of the high never builds overhead, and a persistent W-NW pressure gradient remains, do expect winds to remain in the 10-20 kt range. Wind direction remains N-NW Thursday and Friday, then backs to the W-NW on Saturday.

Seas will remain somewhat elevated as a result, but should fall short of 5 ft.

HYDROLOGY. No hydrologic impacts expected. Only isolated higher rainfall totals of close to 1/2 inch possible near and just east of some of the higher elevations, where orographic lift in SE flow will cone into play.

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

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.
