Synopsis for massachusetts and rhode island coastal waters.. High pressure over new england provides light winds and dry weather tonight into Monday morning. Weak low pressure then tracks south of new england Tue afternoon and night, vsby lowering as snow overspreads the waters. As the low moves out to sea Wed, light nne winds expected across the ma and ri waters. Thursday, powerful low pressure develops off the nc coast, however this storm will track due east, harmlessly out to sea. Although, nnw winds will increase across new england. Friday, an arctic front blast through across ma and ri waters with nnw gales likely along with moderate to heavy freezing spray possible. For additional information on possible hazardous weather for the week ahead, please visit www.weather.gov/boston/ehwo.

Area Forecast Discussion National Weather Service New York NY 343 PM EST Mon Jan 25 2021

SYNOPSIS. Weak low pressure passing to the south will bring a wintry mix to the area on Tuesday. A trough of low pressure will linger nearby for Wednesday and Wednesday night. A coastal storm develops and passes fairly well south of the area late Wednesday night through Thursday. High pressure then slowly builds back in through Saturday. Another low pressure system will then approach from the west and southwest late Sunday into Monday.

NEAR TERM /UNTIL 6 AM TUESDAY MORNING/. Water vapor shows subtropical Pacific moisture streaming newd towards the cwa. This will produce increasing high clouds tngt. The cloud cover may be enough to keep temps from completely bottoming out as the MAV and MET guidance suggest. For this reason, the fcst follows the NBM for temps.

SHORT TERM /6 AM TUESDAY MORNING THROUGH TUESDAY NIGHT/. Theta-E ridge slowly builds into the region on Tue. While there could be some pcpn developing during the mrng, the best chances and steadiest pcpn will come in the aftn and eve as the jet begin to support upr lvl divergence. Low pres will eventually develop off of the Delmarva by early Tue eve, keeping the warm front s of the cwa. The ely flow at the sfc induced by the pres field will attempt to warm the bl, but this is likely only to have a strong enough influence across LI and perhaps portions of NYC and coastal CT. This means there is a significant likelihood that temps across most of the fcst area do not get abv freezing thru Tue ngt.

As the pcpn starts, mainly snow, mixed with sleet, is expected across the entire region. Both the NAM and GFS bufr soundings show the temp profile hovering right around 0C at times, suggesting that bursts of steadier pcpn would fall as snow, with lighter pcpn sleet or a sleet/snow mix. The warm air punch is strongest aft 18Z, so this will help with heavier pcpn rates but also increase the chances for mixing.

After 18Z, there will likely be enough warm air aloft to allow for some fzra to mix in, especially during periods of weak lift. Across LI and perhaps some other areas close to the coast, the bl may be warm enough to preclude any fzra threat.

As the pcpn lightens Tue ngt, it may be difficult to introduce ice due to the lack of deep lift. Therefore the light residual pcpn may fall as -fzra or fzdz at times where sfc temps remain blw freezing.

As a result, a winter wx advy has been issued for all but most of LI. The advy runs to midnight Wed for NYC and adjacent areas in NJ, and until Wed mrng for CT and the Hudson Valley. The chances for freezing rain were the main driver behind the issuance of an advy, as most, if not all, areas are expected to remain blw snow and sleet criteria.

LONG TERM /WEDNESDAY THROUGH MONDAY/. A seasonably cold weather pattern will continue for the long term period. To begin the period a weakening block across Northern Hudson Bay in Canada should prevent any major storms from cutting well west of our area and up into the Lakes. Instead this should force storm systems more west to east and mainly underneath. With the lack of any persistent Western North American ridging the source region of cold air will not be true arctic in nature, but towards more typical Canadian CP type air mass (more in the way of modified arctic air) for the tail end of January. Underneath the block an active Pacific branch will continue to send shortwaves quickly from west to east. Two shortwaves are of interest. The first one will eject quickly east-northeast with a trailing surface trough, and the second one will lead to cyclogenesis along the lower Mid Atlantic and Southeast coast early in the period for later Wednesday night and Thursday. This second system is progged to pass by south of the region and not have impacts on the area. Its predecessor though for Wednesday will likely leave an norlun type trough in its wake which will lead to some very light and intermittent precip during the day, and possibly into a portion of the evening. Precip amounts should be negligible for most of Wednesday and Wednesday evening.

By Wednesday night into Thursday cyclogenesis takes place over the Atlantic waters to our south, then east. At the same time strong high pressure will begin building south and east from the southern Canadian prairies. This will result in a strong pressure gradient developing. A stretch of windy conditions is thus anticipated for Thursday through Friday. As high pressure builds over the region to begin the weekend the winds will relax for Saturday and Saturday night. This will be one of the colder 2 day periods of the winter thus far. Temperatures for Friday and Saturday will average several degrees below average, potentially around 10 degrees below average.

Clouds will increase on Sunday in advance of another Pacific shortwave approaching from the west. This far out there is good general agreement on track and eventually redevelopment along and off the coast into early Monday. Precip chances will increase late Sunday and Sunday night with mainly snow as the ptype. The mid levels may warm enough for a transition to a mix, or perhaps some rain along coastal sections. These details remain uncertain this far out. The system should be progressive enough, that it should progress northeast and way from the area towards Monday night. The global forecast guidance consensus is suggesting that this system will have to be watched for perhaps some winter weather impacts, but there is low confidence and high uncertainty with respect to intensity and precip type for the longevity / duration of the potential event.

AVIATION /21Z MONDAY THROUGH SATURDAY/. High pressure weakens over the area tonight as low pressure approaches from the southwest.

VFR conditions are expected through Tuesday morning for most of the area. A wintry mix will move into the NYC metro terminals after 15Z, with a PROB30 of the wintry mix moving in between 13Z and 15Z along with MVFR conditions. Precipitation will be light with little restrictions to visibility at the onset. Visibilities and ceilings gradually lower after 15Z to MVFR and possibly IFR conditions by afternoon.

NW winds generally less than 10 kt shift to N/NE into this evening and remain less than 10 kt.

Around an inch of snow is expected for KJFK, KLGA, KISP, and KEWR.

1"-2" of snow is expected for most other terminals.

2"-3" of snow is expected for KSWF.

A few hundredths of an inch of ice are possible for KHPN and KSWF. A trace of ice is possible for the NYC metro terminals and KBDR.

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

No unscheduled amendments are expected through tonight.

OUTLOOK FOR 18Z TUESDAY THROUGH SATURDAY. Tuesday Afternoon. Becoming MVFR/IFR in developing light snow/sleet/freezing rain mix. The wintry mix may change to rain for the coastal terminals in the evening. NE gusts near 20 kt at the coastal terminals. Gusts diminish at night. Wednesday. Chance of MVFR/IFR in light mixed precipitation changing to all rain for most terminals. Thursday. Likely VFR with a low chance of rain and snow. NE-N winds 10-20G20-30kts. Friday. VFR. NW 10-20G20-30kt, strongest at the coastal terminals. Saturday. VFR. NW 10-15kt

MARINE. Winds and seas are generally expected to remain blw sca lvls thru Tue ngt. An ocnl 25kt wind gust is possible on the ocean late Tue and Tue ngt.

Sub SCA conditions will take place on Wednesday with gusts around 15 to 20 kts on the ocean zones on a N-NW wind. As low pressure intensifies late Wednesday night into Thursday morning winds and seas will begin to ramp up, with SCA conditions likely for the ocean Wednesday night, and the remainder of the waters into Thursday. Gales will become increasingly likely on the ocean waters by Thursday night and into Friday, with potential gales for some of the eastern near shore waters. Sub SCA conditions should return towards the second half of Saturday from west to east as high pressure begins to settle north of the waters for later Saturday and Saturday night.

HYDROLOGY. No hydrologic concerns are anticipated through the week.
