Area Forecast Discussion National Weather Service New York NY 536 PM EST Tue Dec 7 2021

SYNOPSIS. High pressure over the region will drift into Canada tonight. Low pres will track about 300 miles southeast of Long Island late Wednesday. High pressure returns for Thursday and Friday. A cold front will swing through the region this weekend. High pressure builds back across the region for the beginning of the week.

NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/. Minor updates made to forecast to account for latest observations and trends.

Increasing clouds tngt per stlt. This moisture extends all the way to the Pacific. Temps in the Pine Barrens may drop quickly this eve then rise and stabilize with the clouds overnight. Less dramatic diurnal drops are expected elsewhere. Water vapor shows a mid lvl wave approaching WI where light snow was falling. This features is modeled to approach the area by 12Z. Most of the lgt snow is modeled to remain n of the cwa into Upstate NY. However, portions of the Lower Hudson Valley, particularly nwrn Orange county, may be clipped by some lgt snow by sunrise. The NBM with local adjustments was used for temps tngt.

SHORT TERM /6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT/. The cwa looks to be located between two systems on Wed. The mid lvl wave stays n of the area, and low pres tracks se of the area during the day. The modeling has trended ewd and weaker with the offshore low, so only lgt pcpn at best is fcst for the cwa. With a lack of strong lift and lgt pcpn rates, wet bulbing is not expected to have a significant impact on cooling the column attm. As a result, the warm bl in ern areas especially will limit the potential for any snow at all, with mainly -ra or -rasn most likely attm. Aft 22Z, enough cooling could coincide with the last of the pcpn to produce a lgt coating across ern CT. Any pcpn is progged to wind down by 3Z, with subsidence producing sky for the remainder of the ngt.

The 12Z CONSALL data was used for high temps, and the NBM with local adjustments used for Wed ngt lows.

LONG TERM /THURSDAY THROUGH TUESDAY/. High pressure builds into the region Thursday and Friday with high temperatures in the mid 30s to mid 40s. A weak shortwave is then expected to pass near the region Thursday night, with the best chances of any precipitation falling north of the region. Will keep slight chance POPs for snow showers across our northwest zones on Thursday night. Temperatures Thursday night will be in the mid to upper 20s across inland locations and low to mid 30s across the NYC metro. On Friday night temperatures will be slightly warmer with low temperatures in the mid 30s to mid 40s.

The weekend continues to looks unsettled as low pressure passes east of the region and its associated frontal boundary push across the region. POPs will gradually increase later Friday and Friday night as a warm front approaches and lifts north of the area early Saturday morning. Any precipitation with the warm front should remain fairly light and generally in the form of plain rain except north and west of NYC where snow showers may mix in with the rain. As the front continues to push north, any snow will change over to all rain. The cold front approaches late Saturday and moves across the region late Saturday night into Sunday with precipitation gradually tapering off from west to east on Sunday. Dry conditions are expected behind the front Sunday night and through the beginning of the week.

High temperatures each day through the long term will be at or above normal for this time of year, with the warmest day on Saturday as highs reach the upper 50s and lower 60s.

AVIATION /00Z WEDNESDAY THROUGH SUNDAY/. High pressure continues to build in from the west this evening. Low pressure will pass south and east of the terminals on Wednesday.

VFR conditions are expected through much of the TAF period.

W-NW winds this evening with speeds around 7-10kt. Winds will become light and variable tonight into Wednesday morning.

Uncertainty Wednesday in wind direction and precip type and amount. Any precip is likely confined to eastern terminals and thus has only been added at ISP, BDR, and GON. Went with a mix of rain and snow, but an all rain event is possible, especially for ISP.

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

Uncertainty in wind direction Wednesday. Winds become variable tonight through Wednesday morning. With the low passing to our south, winds could predominantly be out of the northeast by the early afternoon and then out of the northwest by the evening. The TAF reflects this. No precip has been added yet due to the forecast trending drier. If guidance starts trending toward a wetter solution, then a mix of light rain and snow will need to be added.

OUTLOOK FOR 18Z WEDNESDAY THROUGH SUNDAY. Wednesday. Low chance of MVFR conditions in light snow or a rain/snow mix for eastern most terminals. Any precipitation tapers off at night with a return to VFR. Thursday. VFR. Friday and Saturday. MVFR or lower in chance of rain. Sunday. VFR after any rain early Sunday morning.

MARINE. Winds and seas will remain blw sca lvls thru Wed. Seas may approach 5 ft on the ocean late Wed ngt due to low pres over the Atlc, but the probability was too low to issue an advy attm.

Seas fall below SCA conditions on Thursday as high pressure builds across the area waters and remain through Friday night. Small Craft conditions are expected to return for the weekend as a frontal system pushes across the area waters. Below SCA conditions return on Monday across all waters.

HYDROLOGY. No hydrologic impacts are expected thru Tue.

OKX WATCHES/WARNINGS/ADVISORIES. CT . None. NY . None. NJ . None. MARINE . None.
