SYNOPSIS. Low pressure slowly weakens over the Canadian Maritimes this weekend, while high pressure builds in from the west. The high weakens Sunday night and Monday as low pressure approaches. The low passes south of the area Monday night into Tuesday night. High pressure returns Wednesday through Friday. Another low may move south of the region Thursday.

NEAR TERM /UNTIL 6 PM THIS EVENING/. The main change this update was to be less aggressive with the cloud cover today based on latest satellite imagery and mid level shortwave trough exiting by early afternoon.

The combination of high pressure building in from the west and low pressure gradually weakening over the Canadian Maritimes this weekend, will result in a decent pressure gradient across the area through this afternoon. Gusty NW winds are expected through the day and into the evening, gusting 30-35 mph.

Skies will generally remain mostly sunny through the day save for any midlevel stratocumulus during the afternoon that advects in from the northwest. High temperatures will struggle to get into the upper 20s to low 30s, with wind chills in the upper teens today under the brisk northwest flow.

SHORT TERM /6 PM THIS EVENING THROUGH SUNDAY NIGHT/. High pressure continues to build in from the west Saturday night into Sunday morning with dry conditions in store. Low temperatures Sunday morning will be quite cold, in the low teens to near 20 across NYC and western Long Island, under mostly clear skies. Winds should stay up into Sunday morning, which may temper lows a bit. Wind chills will be in the single digits to the low teens. For now went with NBM temperatures, and adjusted toward lower MOS values, especially across the interior and SW CT.

The gusty NW winds will continue overnight Saturday and into the day on Sunday, though less so than on Saturday, 20-25 mph and finally beginning to taper by Sunday evening. Highs on Sunday will moderate somewhat into the lower and middle 30s, closer to normal for this time of year.

LONG TERM /MONDAY THROUGH FRIDAY/. Progressive flow will dominate across the country with near zonal flow. A shortwave moves into the ridge through Monday, reaching the Ohio Valley by 00Z Tuesday. This shortwave passes through the area during Tuesday. Guidance has come into better consensus with the track of the upper ridge and the track and depth of the surface low. There still is some uncertainty with the track and how the system will interact with the northern stream broad longwave trough. The trend has been for a more northern track. At this time the column will remain cold enough for an all light snow event. However, if the northern stream is weaker the storm may track farther north and mixing will be possible along the coast. And if the blocking remains in place with a stronger northern stream, the low will track farther to the south. At this time the precipitation begins Monday evening and continues into early Tuesday evening, with a prolonged period of light snow. Another low does begin to develop off the mid Atlantic coast early Tuesday, and with the progressive flow moves quickly east into the Atlantic. Again, on the current track the potential for higher impacts will be across areas north and west, with lower impacts to areas east of New York City, and portions of southeastern Connecticut, as high pressure remains to the north.

High pressure and a building upper ridge return for Wednesday. Then another southern system quickly moves into the ridge Wednesday night into Thursday, with the potential for another surface low tracking south of the area. Then high pressure returns for Friday.

AVIATION /16Z SATURDAY THROUGH WEDNESDAY/. High pressure will gradually build in from the west while strong low pressure remains in the Canadian Maritimes through the TAF period.

This will set up a steep pressure gradient with gusty NW winds. Conditions are expected to remain VFR through the TAF period.

NW winds will be 15-20 kt this morning with gusts reaching near 25-30 kt late this morning into this afternoon. Some peak gusts between 30 and 35 kt can be expected this afternoon into early this evening. Gusts will lower to more within the 20-25 kt range late this evening and overnight. These gusts will persist into early Sunday.

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

Timing of 30 kt gusts could be off by a few hours.

OUTLOOK FOR 12Z SUNDAY THROUGH WEDNESDAY. Sunday. VFR. WNW gusts 20-25 kt during the day, near 20kt for Sunday evening, gradually diminishing late evening into overnight. Monday. Mainly VFR, but MVFR/IFR developing by Monday evening into Monday night with increasing chances of snow. NW-N under 10 kt. Tuesday. IFR, at times possibly lower, in snow, mainly during the day, with NE winds 10-12 kt with gusts up to near 20 kt. Improving conditions at night with gusts diminishing. Wednesday. VFR. N winds 5-10 kt.

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

MARINE. High pressure is in control with strong NW flow through Sunday. Gales will persist across the ocean waters, the Eastern Sound and Peconic and Gardiners Bays today into Sunday. Elsewhere, SCA are forecast through Sunday. There is a chance of light freezing spray across the ocean waters and western LI Sound for a period late Saturday night into early Sunday, given the combination of subfreezing air temperatures, strong winds and wave action over these areas. Warm sea surface temperatures may mitigate this to be more scattered in nature across the waters.

Winds and ocean seas will be gradually diminishing below SCA levels by Monday morning as the pressure gradient weakens.

Sub SCA conditions are expected Monday through Tuesday. Ocean seas 5 to 6 feet will be possible Tuesday night into Wednesday, with marginal wind gusts, as northerly winds increase behind departing low pressure.

Small craft conditions will once again be possible on the ocean waters Thursday as winds and seas increase with a low that is expected to pass south of the waters.

HYDROLOGY. Mainly dry conditions are expected through the weekend. No hydrologic concerns are anticipated through next week.

OKX WATCHES/WARNINGS/ADVISORIES. CT . None. NY . None. NJ . None. MARINE . Small Craft Advisory until 11 AM EST Sunday for ANZ335-338-345. Gale Warning until 7 AM EST Sunday for ANZ330-340-350-353-355.
