What forecasters said that day
The local office's own words before this winter weather advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS New York, NY wrote its last area forecast discussion before this winter weather advisory went out at Jan 25, 12:31 PM EST, 2 hours 45 minutes earlier.
Area forecast discussion, Jan 25, 12:31 PM EST, 2 hours 45 minutes before
Area Forecast Discussion National Weather Service New York NY 1231 PM EST Mon Jan 25 2021 .SYNOPSIS... Weak high pressure builds in from the west through today and into this evening. This will give way late tonight to approaching multiple low pressure areas. These lows approach Tuesday into Tuesday night. One low to the west eventually dissipates with the one going into Atlantic maintaining its strength going into Wednesday. A coastal storm passes fairly well south of the area late at night through Thursday. High pressure then slowly builds back in through Saturday. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... The fcst remains on track. High pressure gradually builds in from the west but will remain weak. There will be some ridging aloft that will help promote subsidence. Dry conditions prevail today. Highs forecast in the mid 30s to near 40, a consensus of MOS and NBM guidance. && .SHORT TERM /6 PM THIS EVENING THROUGH WEDNESDAY/... The main focus here will be timing and duration of wintry precipitation across the region within the Tuesday into early Wednesday timeframe. The synoptic set up and ambient surface conditions show very limited snow accumulations along the coast where temperatures are expected to reach above freezing but with locations getting farther north and west and inland, surface temperature will be mostly at or below freezing. The combination of lack of ice nuclei at times and low level elevated warm layers above freezing will make for a wintry mix within this event. Overall, light ice and light snow accumulations are forecast, relatively higher across the interior. In confidence increases in these conditions with subsequent forecasts, a winter weather advisory may be needed. The precipitation associated with approaching low pressure has trended slower with numerical weather prediction precipitation forecasts over the last 24 to 48 hours. The frontal system will continue to approach the region from the southwest. The associated surface lows and warm front are still well south of the region. Looking at Jan 25th 00Z guidance, again outside of far western Orange County, Northeast NJ, and NYC, dry conditions expected 00-12Z Tuesday. Most models have front edge of precip from Western PA east southeast through SE PA and Southern NJ into DE 00-06Z Tuesday, and then Western NY State SE through Southern NJ 06-12Z Tuesday. ECMWF shows more expansion of precip and actually gets into a few western locations within the region by early Tuesday morning. For Tuesday, there will be two low pressure areas, one moving from Ohio to Western PA and another moving east of the mid- Atlantic. Western low is weakening with time in its northeastward movement while the one moving out into the Atlantic maintains its strength and some models indicate it to slightly deepen. Overrunning precip develops and moves into the area but is not expected to be intense. Warm air advection aloft and isentropic lift will lead to developing overrunning stratiform precipitation. A rain/snow/sleet mix can be expected along the coast, snow/sleet mix farther interior, with plain snow across the most interior locations. Temperatures along the coast being above freezing with a longer duration steady light precip will make for very little in the way of snow accumulations. Across the interior, snow accumulations of near 1 to 2 inches is forecast where temperatures will stay below freezing longer. Models are coherent in conveying the precip moving across much of the region and conveys a little more precip than previous runs. For Tuesday night, shortwave moves in with positive vorticity advection. The low that was in Western PA eventually diminishes as it moves farther east while further weakening. The low out in the Atlantic will continue moving eastward and maintaining its strength. Precip extends NW from this low into the region. Some additional light snow as well as freezing rain can be expected. Less than a tenth of an inch of precip expected so less than 1 inch of additional snow for the interior and ice accretions is expected to be less than a tenth of an inch. It all depends on how much of a deep saturated layer there is and how much moisture there is in the -10 degree C to -30 degree C layer. Model soundings are indicating a lack of moisture in this layer and thereby implying a lack of ice nuclei with some soundings indicating a slight warm layer above freezing in the 900 to 950mb layer. Along the coast, there is a greater easterly flow and surface temperatures are kept warmer, mid to upper 30s, so mainly rain can be expected. The total precipitation will be less than a tenth of an inch for Tuesday night so made intensity light and if the moisture ends up being shallow enough, may even just be drizzle (freezing drizzle for interior, plain drizzle along the coast). For Wednesday, shortwave axis within the region in the morning and to the east in the afternoon, but with another shortwave approaching from the west. Precip is delayed in this scenario with mostly cloudy conditions remaining in the afternoon when precip is expected to taper off. Again, depending on saturation layer depth and any low level warm layers above freezing, some light freezing rain and snow is forecast across the interior with light plain rain along the coast. POPs decrease to slight chance in the afternoon with mainly dry conditions expected. Dry conditions remain into Wednesday night for the first half but slight chance POPs for mainly snow was maintained for second half of Wednesday night. && .LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/... Moving forward, the next in the series Pac systems in the southern branch will pass off the Mid Atlantic coast Wednesday night into Thursday. The associated surface low undergoes rapid deepening during this time, but global models are all in good agreement with the system passing to our south. Both the GEFS and ECMWF ensemble members are all clustered close to the operational tracks at this time. Thus, will only go with a slight chance of snow late Wednesday into Thursday. It seems unlikely at this time that there would be any accumulation. More importantly though, there is the potential for a surge of cold air behind the system as a piece of the polar vortex drops off to the south and into the area Thursday night into Friday. Gusty NW winds during this time will produce wind chill values in the single digits at night and in the teens during the daytime. Highs on Friday may not get out the 20s. The southern branch returns over the weekend as the polar high gradually retreats Saturday into Saturday night ahead of the next system. There are some differences at this time with the magnitude and progression of the system with the GFS and GGEm the most progressive in bringing winter weather into the area next Sunday. For the time, due to the uncertainty, chances will be low at this time. Temperatures will also moderate over the weekend with highs into the 30s to around 40 on Sunday. && .AVIATION /18Z MONDAY THROUGH SATURDAY/... High pressure will build in from the west today, while low pressure over the Canadian Maritimes weakens. The high then weakens tonight as low pressure approaches from the southwest. VFR conditions are expected through much of the TAF period. A wintry mix will move into the metro terminals after 15Z Tuesday, however there is a chance (PROB30) for the wintry mix to move in between 13Z and 15Z Tuesday along with MVFR conditions. Precipitation will be light and there may be little restriction to visibility until after 15Z, along with ceilings lowering to MVFR. NW winds generally less than 10 kt today. Winds shift to N/NE late this afternoon into this evening and remain less than 10 kt. Around an inch of snow is expected for KJFK and KLGA 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 is possible for KHPN and KSWF. A trace of ice is possible for KTEB and KBDR. ...NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty... No unscheduled amendments are expected through tonight. .OUTLOOK FOR 12Z TUESDAY THROUGH SATURDAY... .Tuesday Afternoon... Becoming MVFR/IFR in developing light snow/sleet mix. The wintry precipitation will change to rain at the coastal terminals in the evening. There is the possibility of freezing rain at the inland 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 Detailed information, including hourly TAF wind component forecasts, can be found at: http:/www.weather.gov/zny/n90 && .MARINE... Conditions should remain below SCA levels today through much of Wednesday night as the center of high pressure moves overhead today and a weakening area of low pressure moves over the area Tuesday night. There may be occasional gusts to 25 kt over the ocean waters Tuesday afternoon as the low approaches the area. The pressure gradient increases late Wednesday night and 25 kt gusts are possible on the ocean waters into Thursday due to the influence of a coastal storm. Too early to be certain, but a potential of gale force gusts on all waters exists during Thursday and Thursday night. Winds and seas subside during Friday, but with advisory conditions likely. && .HYDROLOGY... No hydrologic concerns are anticipated through next week. && .OKX WATCHES/WARNINGS/ADVISORIES... CT...None.
