Area Forecast Discussion National Weather Service New York NY 1042 PM EDT Thu Apr 22 2021

SYNOPSIS. Strong low pressure hovers in the Canadian Maritimes through the overnight and then will gradually weaken as it moves farther northward Friday through Friday night. Meanwhile, high pressure will move eastward out into the Atlantic Friday night into 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 Wednesday and Thursday.

NEAR TERM /UNTIL 6 AM FRIDAY MORNING/. For this update, adjusted clouds up just a little bit for the next few hours, before clouds dissipate completely. A cyclonic flow aloft has been responsible for the clouds with strong low pressure within the Canadian Maritimes. After a shortwave during the first half of the night, heights will start to rise overnight and some subsidence will start to decrease the cloud coverage overall. Any scattered flurries that took place earlier in the evening will completely shut off. With still a fairly steep pressure gradient in place the winds will be gusty at times, although some outlying areas will lose gusts from time to time. Closer to the coast and within NYC, gusts are expected to continue but will be decreasing overall in magnitude.

Radiational cooling will be more optimal across the interior. Confidence for freezing or lower temperatures remains high enough for the interior so there is a freeze warning for Passaic and Western Bergen NJ, the Lower Hudson Valley except for Southern Westchester NY and interior Southern CT. These locations have a pretty high likelihood or dropping to 30 to 33 degrees for low temperatures, considering most of the guidance is below freezing including runs of the LAMP guidance for the overnight into early Friday.

Less confidence for freezing temperatures closer to the coast including the rest of Northeast NJ, NYC, Long Island, and coastal sections of CT where lows are generally expected to be more in the mid to upper 30s, but near 40 for NYC. Still think the gusty winds will prevent the formation of frost so no frost advisories are expected at this time.

SHORT TERM /6 AM FRIDAY MORNING THROUGH FRIDAY NIGHT/. The upper level low and surface low will gradually move farther northward within the Canadian Maritimes. The surface low will gradually weaken. Meanwhile, high pressure based in the Southeast US on Friday will move eastward out into the Atlantic Friday night.

The NW gusty flow will be in place for Friday but less than the previous day and will diminish more substantially for Friday night. The national blend of models was used for the high temperatures and these will be trending higher with some warmer air advecting into the region with veering winds from low to mid levels. Forecast highs are in the upper 50s to lower 60s for much of the region. More sun is expected with the ridging aloft promoting more subsidence.

The mostly clear conditions are expected to continue Friday night and with winds diminishing more, more optimal radiational cooling conditions are expected. The airmass will be moderating however with slightly warmer air at 850mb getting advected into the region. The lows forecast are a combination of MOS consensus and national blend of models, ranging from the upper 30s to upper 40s.

LONG TERM /SATURDAY THROUGH THURSDAY/. 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 /03Z FRIDAY THROUGH TUESDAY/. High pressure builds towards the area overnight and pushes off the southeast coast Friday afternoon.

VFR conditions through the TAF period.

W to NW winds diminish to a degree overnight, with gusts falling to 20 kt or less. Gusts will stop for a few hours into early Friday morning at outlying terminals. Gusts return Friday morning, although they should not be as strong as previous, with W winds gusting to 25-30 kt.

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

Cannot rule out a few amendments overnight with respect to wind gusts, otherwise no amendments anticipated.

OUTLOOK FOR 0Z SATURDAY THROUGH TUESDAY. Friday night. VFR. W winds diminish during the evening, with winds only at 5 kts or less towards the early AM. Saturday. VFR. Saturday night-Sunday. MVFR/IFR in rain. Monday-Tuesday. VFR.

MARINE. Gusts will remain at SCA levels through Friday afternoon, and on the ocean waters into Friday evening. Ocean seas will also be subsiding to below SCA by Friday evening. The gale warnings have been downgraded to SCAs.

Sub-SCA conditions are forecast across all waters Saturday and Saturday night as high pressure moves offshore and low pressure approaches Saturday night. As the low tracks south and east of Long Island Sunday into Sunday night, while deepening, SCA conditions are expected to develop Sunday as both winds and seas increase. As the low moves off to the northeast, winds will shift to the NW with SCA gusts continuing across all the waters Sunday night before gradually diminishing from west to east, as high pressure builds west of the waters, during the day on Monday, and by Monday evening both winds and seas will likely fall below SCA levels on all waters.

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

There is still SPS for NJ and CT for elevated risk of wildfire spread into early this evening with wind gusts up to near 30 to 35 mph and relative humidity down to around 30 percent. The SPS includes the entire region for Friday. Friday will feature winds just a little less gusty than the previous day, up to near 30 mph but with lower relative humidity, between 20 and 30 percent.

Rainfall amounts near 0.25 to 0.50 inches from Wednesday in some areas will likely factor into how quickly fine fuels can dry out. There will be some spots that have less moisture than others in terms of ground moisture.

HYDROLOGY. No hydrologic impacts are expected through the period.
