  (on/off)  Help NOTE: mouseover dotted underlined text for definitionFxus61 kokx 180246 afdokx area forecast discussion national weather service new york ny 946 pm est Sun feb 17 2019 Synopsis Low pressure approaches from the south and west, then redevelops to our south and passes to the south and east late tonight into Monday morning. High pressure briefly returns for Tuesday, followed by another low pressure system for Wednesday into Thursday. High pressure then returns for Thursday night into Friday. Near term until 6 am Monday morning Precip beginning to break out across the region this evening. There are growing concerns with lack of snow growth aloft as reports of mainly rain with a few ice pellets in NE nj and across the nyc metro. Light snow has been reported across the interior where best frontogenetic forcing may set up through the night. Made some minor adjustments to the snowfall forecast, mainly for the coast to lower just a bit. Otherwise, potential still exists for 2 to 4 inches across the interior of the lower hudson valley, interior ct and interior ne nj with 1 to 3 inches for coastal ct and portions of NE nj closer to nyc. These amounts are less certain due to potential of earlier mixing cutting down on totals. There will be a transition to a wintry mix of light snow and fzra towards daybreak all advisory area as mid levels level begin to dry but ample low-level moisture remains ahead of approaching shortwave. A light glazing of ice on top of snow covered roads likely for the morning commute in this advisory area. For LI and nyc nj metro, this area may be in between two best frontogenetic zones to the N and S overnight. The north shore of li and norther nyc could see around an inch with less than an inch across the southern half. If precip intensity remains light, the amounts may be further reduced. Any wintry precip should transition to all rain in these locations around 1-2am southern half to 2-4 am northern half. Do not think temperatures will stay at or below freezing for long, if they do in fact drop to these levels so no significant icing concerns. Short term 6 am Monday morning through Monday night Only low level moisture will remain into the first half of Monday with any snow and ice tapering off early across far northeastern sections of ct, and some leftover drizzle and light rain for the remainder of the cwa. May take a little while to clear out during Monday afternoon, but increasing cold air advection should aid in drying and clearing things out by the late afternoon. Temperatures will drop well below average into Monday night with teens north and northwest, with widespread lower 20s closer to the coast, with some single digit and lower teen wind chills late at night and early Tuesday morning. Winds may briefly gust to 30 mph in some locations during Tuesday evening as the storm intensifies and pulls away out over the atlantic. Long term Tuesday through Sunday The region transitions under a confluent upper flow Tue into wed, between upper ridging south of bermuda and polar low sliding across central quebec and canadian maritimes. At the surface, canadian high pressure builds overhead on Tuesday into Tuesday night and then slides eastward Wednesday. Region comes more under the influence of the southern stream midweek, as early week SW us trough shears eastward towards the great lakes and new england, while SW troughing is reinforced once again. In the SW flow aloft, weak southern stream energy lifts up towards the region Tue night into wed, with associated southern low gradually approaching Wed and tracking near the region thu. Although forcing with this system does not look to be overly strong, deep layered lift ahead of shortwave and right rear of 175+ kt llj combined with gulf tap of 2-3 +std pwats is trending towards a moderate precip event for late Wed into Thu morning. Thermal profiles appear cold enough to start as all snow Wed wed eve, then gradually transitioning to wintry mix interior and all rain city coast Wed night into Thu morning, before gradually tapering off thu afternoon as mid-level shortwave passes. Too early to talk about snow ice amounts, but potential for a light snow sleet accumulation, before transition to rain city coast, and some icing interior. Thereafter, generally zonal pac influenced upper flow for late week into the weekend, lending to slightly above seasonable temps. Next feature of interest will be the timing amplitude of the late week sw trough as it ejects eastward across the country this weekend. Considerable timing spread exists, as well as degrees of interaction with northern stream. With available gulf moisture, this energy will likely bring the next chance of significant precip from low pressure s. At this point too much uncertainty in evolution to diagnose p-types. Aviation 03z Monday through Friday |
Low pressure will impact the terminals into Monday. Light SE winds will continue to shift to the E as the wintry mix develops overnight and then NE by day break. The flow will become NW by Monday afternoon and increase into Monday evening becoming gusty, 20-30 kt. Conditions will lower to MVFR and ifr overnight as a wintry mix develops. Precipitation tapers of to a drizzle Monday morning with gradual improvement into the evening. The precipitation type is expected to rapidly transition to rain 06z-09z at nyc terminals and kisp. Elsewhere, a wintry mix including a few hours of -fzdz, especially at kswf, khpn and kbdr may be possible into the late morning. Conditions should gradually improve Monday afternoon. There is the potential for 2 to 3 inches of snowfall overnight at kswf with 1 to 2 inches most elsewhere. Lowest totals expected for nyc terminals and kisp where generally less than an inch is forecast before changing to rain. Outlook for 00z Tuesday through Friday Monday night into Tuesday Vfr. NW winds g20-30kt for the evening into overnight, diminishing early Tuesday morning. Wednesday Snow possible with MVFR or lower conditions in the afternoon and evening, changing to a wintry mix at night. Thursday MVFR or lower in a wintry mix inland and rain at the coast in the morning. NW gusts 15-20 kt possible in the evening. Friday Vfr. Marine Low pressure approaches from the southwest, passing to the south and east late tonight into Monday. Sub SCA conditions are expected tonight through much of the day on Monday, before winds and seas increase later Monday afternoon. SCA conditions will then return to the ocean waters, and the eastern sound and eastern bays during Monday night. This will be a short-lived event though as high pressure quickly builds into the waters on Tuesday with conditions falling below sca. The next chance for SCA conds will likely be Wed night through thu night with the next low pressure system moving over the waters. Hydrology There are no hydrologic concerns through the end of the week. Tides coastal flooding A low pressure system tracking to the south of the region tonight into Monday, and a full moon on the 19th, will combine to bring localized minor coastal flooding during the Monday morning high tide. Affected areas will be the most vulnerable locales of the south shore bays of queens and nassau county, W long island sound, and along lower ny nj harbor. Surge of 1 to 1 1 2 ft and, locally 2 ft, is needed for minor flood thresholds to be reached. Equipment Nyc central park winds are out of service until further notice.
