Area Forecast Discussion National Weather Service New York NY 718 AM EDT Thu Apr 22 2021

SYNOPSIS. Deepening low pressure over the Canadian Maritimes will slowly lift north and east today, becoming nearly stationary tonight, then slowly weakening and resuming its trek northward on Friday. At the same time, high pressure builds to the south and west, passing offshore on Saturday. Low pressure approaches from the southwest late Saturday and passes to the south and east on Sunday. High pressure then builds in from the west Sunday night into Monday before settling over the area on Tuesday. The high shifts offshore on Wednesday.

NEAR TERM /UNTIL 6 PM THIS EVENING/. A few flurries or very light snow showers have been able to reach the ground early this morning across portions of the New York City metro area and interior southern Connecticut. This activity should quickly come to an end this morning.

Gusts have been lost in some locations and those that are gusting seeing about 20 to 25 mph. Winds will ramp back up in the new few hours as heating ensues and the depth of the mixed layer increases.

Deepening low pressure over the Canadian Maritimes and high pressure building to the south and west will maintain a strong pressure gradient across the region. This will result in strong west winds with gusts up to 35 mph (a few higher gusts possible).

Deep-layered cyclone flow will allow for instability clouds to form above 5000 ft late this morning into this afternoon. A mostly sunny start will transition to partly to mostly cloudy.

At the same time, an unseasonably cold airmass will be in place for late April, with highs struggling to get much above 50. This will be about 10 degrees below normal and will feel even colder with the gusty west winds.

SHORT TERM /6 PM THIS EVENING THROUGH SATURDAY NIGHT/. Winds will slacken somewhat tonight with the loss of the deep daytime mixing. Still though, gusts up to 25 mph will be possible and even with mostly clear skies, the radiational cooling component will be hindered. The airmass will moderate somewhat as well. Confidence for freezing or lower temperatures is not sufficient enough at this time to issue another freeze watch or warning, but it's not out of the possibility. The best chance at this time would be across the western half of Orange County in the Lower Hudson Valley.

Friday will continue to be gusty, but less so than prior day, and temperatures will to seasonable levels with highs generally in the lower 60s.

As low pressure weakens Friday into Saturday, gusts will be lost Friday night and high pressure will build in from the southwest. Conditions will remain dry and mild on Saturday as the high builds offshore and winds turn around to the south in the afternoon.

Global models remain in good agreement with a progressive southern branch low that interacts with a northern branch shortwave trough moving across the Great Lakes. There has been no indication at this time of phasing of the two branches. Rain from the system will overspread the area from SW to NE during the evening and into the overnight hours.

LONG TERM /SUNDAY THROUGH WEDNESDAY/. The upper trough crosses the area on Sunday, with its associated surface low passing south of Long Island during the day. After a wet start to the day, rain will taper off from west to east during the afternoon as the low moves east of the area. Gusty northwest flow then develops Sunday night into Monday as the pressure gradient tightens between the departing low and high pressure building to the west.

The high builds over the area on Tuesday before shifting offshore on Wednesday. With rising heights aloft, this should lead to a gradual warming trend. After near normal temperatures on Sunday and Monday, temperatures return to above normal Tuesday, and by Wednesday temperatures may be as much as 10 degrees above seasonal normals.

AVIATION /11Z THURSDAY THROUGH MONDAY/. Low pressure continues to exit to the northeast. High pressure builds towards the area today.

VFR conditions through the TAF period.

WNW winds will increase this morning with gusts to 30-35 kt from late this morning through the afternoon. Winds then decrease this evening, with gusts falling to 25 kt or less at coastal terminals. Gusts may come to an end entirely for a few hours very late tonight into early Friday morning at outlying terminals.

MARINE. Marginal gales will continue across all waters today and into this evening, ending on the non-ocean waters first. There is the possibility that the gales will need to be lowered earlier as the gusts may become more occasional at 35 kt late in the day. SCA conditions will remain across the waters on Friday with only lingering 5 ft seas on the ocean Friday night as high pressure builds in from the southwest. Sub-SCA conditions are forecast across all waters Saturday and Saturday night.

SCA conditions will develop on Sunday as both winds and seas increase in response to deepening low pressure passing south of Long Island. As the low moves off to the northeast, winds will shift to the NW with SCA gusts continuing Sunday night before gradually diminishing during the day on Monday. By Monday night, both winds and seas will likely fall below SCA levels on all waters as high pressure begins to build across the waters.

FIRE WEATHER. An SPS has been coordinated with the state of CT for the mention of elevated risk of wildfire spread should ignition occur.

Both today and Friday will pose an elevated risk of wildfire spread due to low RH and gusty west winds. Min RH values both days will generally be less than 30 percent.

Rainfall amounts on the order of 0.25 to 0.50 inches from Wednesday will likely factor into how quickly fine fuels can dry out. This should occur quickly though due to strong west winds and low RH values. The greater risk for potential fire spread appears to be on Friday.

HYDROLOGY. No hydrologic impacts are expected through the period.
