SYNOPSIS. A cold front will move through tonight. The region will then become situated between strong low pressure over the Canadian Maritimes and high pressure across southern Canada into Saturday. The high will build over the region Sunday into Monday, then shift to the south and east into the middle of next week.

NEAR TERM /UNTIL 6 AM THURSDAY MORNING/. A cold front and vigorous mid level shortwave disturbance will pass through this evening, followed by winds shifting to NW as colder air returns. Temperatures will return closer to normal levels by Thursday morning with lows 25-30 north, and in the lower/mid 30s closer to the coast and NYC metro.

SHORT TERM /6 AM THURSDAY MORNING THROUGH THURSDAY NIGHT/. There could be some lake effect clouds in the AM well NW of NYC, otherwise looking at a mostly suny and brisk day, on Thu with highs near the seasonal avg, mainly 40-45 with a brisk NW flow gusting to 25-30 mph.

Winds will take some time to diminish Thu night. The night should be mostly clear, though some clouds from the Canadian Maritimes low may get into S CT and eastern Long Island late Thu night. Low temps should reach 15-20 inland/Pine Barrens and 20-25 elsewhere. with wind chills as low as 10 above in NYC and single digits elsewhere.

LONG TERM /FRIDAY THROUGH WEDNESDAY/. A deep and anomalous upper low will remain nearly stationary over the Canadian maritimes Friday into much of the weekend. This upper low carves out a mean trough over the eastern seaboard and western Atlantic. Ensemble means all generally agree that the upper low begins to weaken on Sunday before it lifts out into the north Atlantic into Monday. The position of the upper low will hold upper ridging across the Rockies/Great Plains and up into Central Canada. The ridging only slowly shifts eastward on Sunday as the upper low weakens.

The aforementioned pattern supports dry and unseasonably cold conditions Friday through the weekend. The Tri-State area will be sandwiched between the low pressure over the Canadian Maritimes and high pressure to our west. A deep layered NW flow will persist during this time ushering cold and dry air into the region. High temperatures will generally be in the lower and mid 30s for most locations, with the NYC metro slightly higher in the mid and upper 30s, close to 10 degrees below normal. Nighttime temperatures will be in the upper teens and lower 20s inland, to the lower and mid 20s most elsewhere. The strongest pressure gradient is currently progged on Friday, with gusts 30-35 mph possible, making it feel like it is in the teens for much of the day. While it will remain brisk on Saturday, the pressure gradient is weaker and winds may gust to around 20 mph. The surface high builds closer on Sunday, but the core of the high is likely to not move overhead until Sunday night.

The trough carved out by the deep low to our northeast finally shifts offshore late Sunday into Sunday night. Heights aloft will rise significantly Sunday night into early next week. An initial ridge axis shifts through on Monday, followed by a warm front passage on Tuesday, with high pressure settling to our south. The overall pattern evolution supports a significant warming trend next week, with temperatures possibly approaching 60 degrees away from the immediate coastline. Not ready to boost temperatures higher than consensus blends right now due to the time range. However, if trends continue, temperatures may need to be raised farther away from the coast.

AVIATION /21Z WEDNESDAY THROUGH MONDAY/. High pressure remains in control with only a weak surface trough passing through this evening.

VFR. Westerly winds 10-15 kt with gusts near 20 kt. Winds diminish this evening, shifting NW. Winds increase late morning with gusts up to 25 kt by the afternoon out of the northwest.

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

Start and end times of frequent gusts can be an hour or two off.

OUTLOOK FOR 18Z THURSDAY THROUGH SUNDAY. Thursday through Monday. VFR. NW winds 10-15 kt.

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

MARINE. Buoy data has returned and confirms earlier suspicion of minimal SCA conds continuing on the outer coastal ocean waters E of Moriches Inlet, so that SCA will stand until 7 PM.

After a lull tonight, the pressure gradient will then increase on with at least SCA conditions on all waters from mid morning Thu through Fri afternoon, and possible gales Thu night on the outer ocean waters, with a gale watch in effect. The pressure gradient begins to relax thereafter, with lingering SCA conds on all but the Harbor and W Sound gradually easing Fri evening.

While wind gusts up to 20 kt are possible this weekend, conditions are expected to remain below SCA levels. Relatively tranquil conditions are forecast on Monday with high pressure settling over the waters.

HYDROLOGY. No hydrologic impacts through early next week.
