Area Forecast Discussion National Weather Service New York NY 334 AM EST Sun Jan 17 2021

SYNOPSIS. Low pressure gradually lifts up into the Canadian Maritimes through tonight. 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 Thursday and Thursday night. High pressure slowly builds into the beginning of next weekend.

NEAR TERM /UNTIL 6 PM THIS EVENING/. Low pressure will continue tracking towards the Canadian Maritimes today. Cyclonic flow aloft will continue through much of the day as the upper level low and surface low become vertically stacked by this afternoon.

The main story today will be the breezy W-SW winds. While there is cold advection early this morning, gusts have been occasional so far. A well mixed boundary layer and a relatively steep pressure gradient will lead to sustained winds and gusts increasing after sunrise. W-SW winds 15-20 mph with gusts 25-35 mph are expected from late this morning into the afternoon. The pressure gradient relaxes a bit late this afternoon and we should see winds weaken towards sunset.

The well mixed boundary layer and westerly flow should allow temperatures to warm a bit higher than previously anticipated. Have sided closer to the warmer MAV guidance, which yields highs generally in the middle 40s, but could see some locations near the coast reach the upper 40s.

SHORT TERM /6 PM THIS EVENING THROUGH MONDAY NIGHT/. The low pressure system lifts further northeast away from New England, but there will still be lingering pressure gradient. Winds will be much weaker than during the day, but still should see an average of 5-10 mph through the night as the boundary layer is unlikely to become complete decoupled even across the interior. Aloft, brief ridging moves overhead the first half of the night before heights begin falling ahead of the next upper trough. Partly cloudy skies to start the night will become mostly cloudy early Monday morning as the upper trough approaches. Lows will remain above normal in the upper 20s inland and the lower 30s elsewhere.

The upper trough will slide across the region on Monday. There will also be a weak surface trough passing through in the afternoon. Lift is weak with the troughs, but have maintained mention flurries inland and either flurries or sprinkles elsewhere late morning into the early afternoon. There is a dry subcloud layer so if any precipitation does make it to the surface, there could be flurries despite surface temperatures in the lower 40s. Due to the weak lift, have also mentioned potential of sprinkles where wet bulbs are a bit higher. Otherwise, the upper trough axis moves east of the area late in the day. Highs will be generally be in the 40s. It will remain breezy with potential for gusts 20-25 mph.

Another weak northern stream shortwave may pass Monday night. Initially, subsidence behind the passing shortwave will lead to mostly clear skies. There may be increasing clouds late Monday night as the flow becomes westerly and middle level moisture advects towards the area. A NW flow and cold advection Monday night should allow temperatures to fall into the 20s for much of the area except the NYC metro where lows will be in the lower 30s.

LONG TERM /TUESDAY THROUGH SATURDAY/. The flow begins to amplify on Tuesday as a longwave trough swings across the Great Lakes region. Dry conditions will prevail on Tuesday, but there will be varying degrees of cloudiness ahead of the approaching longwave trough. Temperatures on Tuesday will slightly above normal in the upper 30s to near 40 degrees.

The approaching longwave trough moves through early Wednesday, and with the atmosphere cold enough through the column, flurries or snow showers will be possible across the entire region. Another less amplified wave moves through for Thursday into Thursday night. Models continue to indicate limited moisture and a progressive nature to the system with a weakening parent low and new low development well offshore. Have maintained low chance PoPs for some light snow with this system. However, if current model trends continue, then these may need to removed. There is also some uncertainty with a system for next Saturday with much of the energy remaining to the north as weak ridging builds slowly from the Great Lakes region.

AVIATION /08Z SUNDAY THROUGH THURSDAY/. Low pressure over northern New England moves into the Canadian maritimes later this morning.

VFR. BKN ceilings possible around 4000-4500 ft this afternoon.

Gusty west winds will be the rule the next 24 hours as deepening low pressure lifts up into the Canadian Maritimes. Expect speeds 10 to 15 kt early with gust up to 20 kt, increasing to 15 to 20 kt with gusts to 30 kt after 14Z.

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

Wind gusts may be less frequent through early this morning.

OUTLOOK FOR 06Z MONDAY THROUGH THURSDAY. Monday. VFR. W wind gusts 15-20 kt, mainly during the day. Tuesday. VFR. Wednesday. Mainly VFR, chance of MVFR. Thursday. Mainly VFR.

MARINE. A strong pressure gradient will be over the waters today as low pressure slowly lifts into the Canadian Maritimes. Gales are likely on the ocean waters east of Moriches Inlet through this afternoon. There may also be occasional gusts to 35 kt on the ocean waters from Fire Island Inlet to Moriches Inlet. Otherwise, SCA conditions are expected on all waters through this afternoon. Winds should begin to weaken this evening on the NY Harbor and Western Sound. Winds on the Eastern Sound and LI Bays will take a bit longer to weaken, but winds should be below SCA by midnight. SCA conditions continue on the ocean tonight with winds gradually falling below 25 kt through early Monday morning. This lull in SCA winds is brief as there could be gusts to 25 kt on Monday and Monday night east of Fire Island Inlet. Elevated ocean seas will continue today before subsiding tonight into Monday. However, seas should still be above 5 ft on much of the ocean Monday night.

SCA conditions are likely on the ocean waters, and possibly the eastern Long Island Sound and eastern bays Tuesday into Wednesday night. A brief period of sub advisory is expected Thursday, however, ocean seas build back to SCA levels Thursday night into Friday as southwesterly winds increase ahead of a frontal system.

HYDROLOGY. No hydrologic concerns are anticipated through next week.

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.
