Area Forecast Discussion National Weather Service New York NY 637 AM EST Mon Jan 18 2021

SYNOPSIS. Low pressure over the Canadian Maritimes will lift slowly north today and send a surface trough across the region during the late afternoon and early evening hours. Thereafter, a series of weak troughs along with a cold front will pivot across the area through the middle of the week. A frontal system passes through the area Thursday into early Friday. High pressure slowly builds through next weekend.

NEAR TERM /UNTIL 6 PM THIS EVENING/. Forecast on track. Only minor adjustments have been made with this update, generally to temperatures and dew points. Skies have become mostly clear through much of the area though some scattered clouds linger along the south shore of Long Island.

A weak trough, both at the surface and aloft, will move through the area today. Lift is weak and there is not much moisture to work with but the development of flurries or sprinkles are possible, mainly in the afternoon thanks in part due to daytime heating and resultant additional BL mixing. Other than the slight chance of flurries/sprinkles, the day will be mainly dry with partly to mostly cloudy skies and highs in the low to middle 40s. Winds will remain fairly breezy out of the west with gusts up to 20 - 25 mph.

SHORT TERM /6 PM THIS EVENING THROUGH TUESDAY NIGHT/. Upper level flow remains zonal with weak shortwaves moving through tonight and Tuesday. This will allow for the reinforcement of the breezy conditions (and cold air) generally out of the west, especially during the day on Tuesday with the additional daytime heating and mixing.

The shortwaves that move through will really only produce some cloud cover for short periods of time. Conditions will be generally mostly sunny to partly cloudy Monday night, but may become mostly cloudy or briefly overcast during the day on Tuesday before clearing out again early Tuesday night.

Overall, a fairly benign pattern with the main forecast challenges being cloud cover and timing of strongest wind gusts. Temperatures will be seasonal with daytime highs on Tuesday in the low 40s and low temperatures tonight and Tuesday night in the 20s with the NYC metro in the low 30s.

LONG TERM /WEDNESDAY THROUGH SUNDAY/. The northern stream will dominate through the extended period, and the general forecast remains consistent. Wednesday a shortwave moves across the area and the surface low over the Atlantic deepens further. A surface trough lingers back across New England and this may provide enough forcing for flurries as little moisture will be available. Again rather flat upper flow develops behind the trough Wednesday night into Thursday. As a result the next shortwave remains to the north and at this time is not as amplified as earlier forecasts. This will keep the surface low, and warm frontal boundary farther to the north. And once again with the progressive flow the low forming on the occluded front will be to the east of the region and deepen well to the east Thursday night into Friday. As a result did lower the probabilities for Thursday and Thursday night. Heights begin to rise Friday as a ridge builds over the central United States and moves toward the east coast through the weekend.

AVIATION /12Z MONDAY THROUGH FRIDAY/. A surface trough crosses the terminals during the late afternoon and early evening hours.

VFR through the TAF period. There could be a few sprinkles or flurries this afternoon, but no impacts to ceilings and visibility are expected.

WSW winds increase this morning, becoming 10-15 kt with gusts 18-23 kt late this morning into the afternoon. Winds will veer towards the WNW early this evening with the passage of the surface trough. Gusts should end by around 00z with sustained winds gradually falling below 10 kt tonight.

NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty .

Timing of onset of wind gusts may be off 1-2 hours. Gusts may be more occasional than frequent, especially before 18z.

OUTLOOK FOR 12Z TUESDAY THROUGH FRIDAY. Tuesday. VFR. W wind G15-20KT, mainly near the coast. Wednesday. Mainly VFR. WNW wind G20-25kt. Thursday. Mainly VFR, Low chance of MVFR. Friday. VFR.

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

MARINE. On the ocean, SCA conditions continue for areas east of Fire Island Inlet though there may be a brief lull in the wind speeds early this morning. Winds pick back up to 25 kt by this afternoon allowing the western ocean zone to be included in the SCA. Seas east of Fire Island inlet will remain at or above 5 ft through at least tonight.

SCA conditions are likely on the ocean waters Tuesday into Wednesday night, with SCA possible on the eastern Long Island Sound and the Long Island bays Wednesday and Wednesday night, as low pressure tracks across southern New England Tuesday and deepens over the western Atlantic Wednesday. A brief period of sub advisory is expected Thursday, however, ocean seas build back to SCA levels Thursday night into Friday as another low develops and deepens east of the waters.

HYDROLOGY. No hydrologic concerns are anticipated through this week.

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.
