SYNOPSIS. Strong high pressure extending from the Plains states to the Great Lakes will gradually build into the Northeast through Friday night. A developing wave of low pressure passes well offshore on Saturday, with dry, cold conditions expected through the weekend. A weak low pressure passes nearby on Tuesday, bringing the chance of some light rain and snow, followed by a return to below normal temperatures for midweek.

NEAR TERM /UNTIL 6 AM FRIDAY MORNING/. BKN-OVC high clouds extend across the NYC metro area eastward into Long Island and coastal CT. These should gradually decrease going into this evening, with a mostly clear night expected. Temps will fall on a steady N wind 10-15 mph metro/coast and 5-10 mph inland, ushering in very cold air. Lows by morning should be in the single digits inland and in the lower/mid teens metro/coast, with wind chills running at least 10 degrees colder. Will issue SPS for NYC where wind chills should approach zero, and for the entire area as the combo of light snow and sub-freezing temperatures could result in icy roads.

SHORT TERM /6 AM FRIDAY MORNING THROUGH FRIDAY NIGHT/. Cold weather will be the main story. A positively tilted northern stream trough located to our west Thursday night will gradually work its way east through Friday night, while a large area of high pressure gradually builds eastward. Skies should be mostly clear during this time, with highs only in the 20s on Friday, followed by lows near zero well inland, in the single digits closer to the coast, and in the teens across Long Island and the NYC area. The pressure gradient between the high and offshore low pressure will maintain a steady N wind Fri night, which should again result in wind chills near zero in NYC, and 0 to 5 below elsewhere.

LONG TERM /SATURDAY THROUGH THURSDAY/. The period begins unseasonably chilly, as weakening high pressure over New England allows for a cold northerly flow for much of Saturday. Thanks in part to this high, global models are consistent in keeping a developing wave of low pressure along an offshore boundary well out to sea, with only an increase in cloud cover expected, particularly across eastern Long Island, where a few flurries are possible early Saturday.

Otherwise, dry conditions are expected into Sunday, which should be a few degrees milder than Saturday, as a more zonal flow develops across the region. A cold front with limited moisture passes through late Sunday, delivering a reinforcing shot of cold air into early next week. 850mb temps fall to near -15C early Monday with the upper trough axis overhead, which should keep most of the area under the freezing mark during the afternoon as high pressure builds at the surface.

Tuesday looks to be the warmer day of the period, with heights rising ahead of an approaching clipper low and the associated warm front lifting through. Boundary temps appear marginal at best for wintry ptypes along the coast, though any precip likely falls as snow across the interior. Meanwhile, a piece of energy in the southern branch will be moving across the Southeast. While most of the global ensembles show little interaction with these two features given temporal and spatial differences, a few members highlight the potential of the two pieces phasing together. Capped PoPs at chance for this time period as the disagreement resolves.

Another lobe of arctic high pressure swings down from Canada with temperatures falling back to below normal by mid-to-late next week. Stuck close to the NBM for temperatures, with conditions generally below normal through the extended period.

AVIATION /21Z THURSDAY THROUGH TUESDAY/. High pressure builds in this evening through Friday.

VFR through the TAF period.

Winds NW-N around 10 kt with gusts to 20 kt possible. Gusts linger into Friday but generally 20 kt or less.

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

No unscheduled amendments are expected. Gusts may be infrequent overnight.

OUTLOOK FOR 21Z FRIDAY THROUGH WEDNESDAY. 21Z Fri. VFR. N-NE winds near 10-15 kt. Fri Night. VFR. NE winds 10-15 kt with gusts up to 20 kt. Sat. Mainly VFR. NE winds 10-15 kt with gusts up to 20 kt in the morning, subsiding in the afternoon and becoming more northerly. Sat Night-Mon. VFR. Tue. MVFR or lower possible in snow or rain. Wed. VFR. N winds 15 kt with gusts up to 25 kt.

MARINE. SCA on the ocean waters extended into Fri morning, though conds are rather marginal and may only take place closer to 20 nm offshore. For tonight, N winds increase to around 20 kt, so gusts up to 25 kt and seas up to 5 ft are possible on the outer waters during this time. Marginal SCA conditions are possible on Saturday, especially early in the day.

HYDROLOGY. No hydrologic impacts expected through the middle of next week.

The river gauge at the Wallkill River at Gardiner may be impacted by ice.
