The local office's own words before this special weather statement 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 special weather statement went out at Aug 8, 10:37 PM EDT, 2 hours 45 minutes earlier.
Area forecast discussion, Aug 8, 10:37 PM EDT, 2 hours 45 minutes before
Area Forecast Discussion National Weather Service New York NY 1037 PM EDT Wed Aug 8 2018 .SYNOPSIS... A weak frontal system will approach tonight and pass offshore on Thursday. A frontal boundary approaches Friday, and may stall nearby this weekend into early next week. && .NEAR TERM /THROUGH THURSDAY/... Highest coverage of shower/tstm activity remains to the N of the forecast area with storm motion to the NW. SBCAPE remains around 2k J/KG and with outflow boundaries around from earlier convection have maintained CHC pops for the next couple of hours. As the upper trough approaches overnight, heights will begin to fall and although there won't be as much instability as the during the daytime, shower/tstms coverage may begin to increase. 00z sounding still juicy with PW's of 1.88 inches so any additional convection that does develop has the potential to produce heavy rain. The upr trof will be slow to exit on Thu. This will likely spark additional shwrs and tstms during the day, especially before 18z. Heat indices on Thu are very close to the 95 degree threshold for the usual warm spots, including the city. Right now however, they are just shy due to lower dewpoints, but mid shift can reevaluate. There is a low risk for rip current development at Atlantic Ocean beaches on Thu. && .SHORT TERM /THURSDAY NIGHT/... Subsidence behind the upr trof will allow for any residual pcpn to rapidly end. The fcst has been kept dry based on the current model timing. Limited moisture on nw flow is progged to produce mainly clr skies, although some cirrus currently over the midwest may advect in. && .LONG TERM /FRIDAY THROUGH WEDNESDAY/... Dry conditions expected Friday as weak high pressure builds across the area. Temperatures should peak on Friday in the mid to upper 80s. Heat indices on Friday will stay below 95. A weak cold front will then be stalled nearby Friday night through the weekend. This brings a chance of showers and thunderstorms for the entire period with the higher chances generally away from the coast. Temperatures over the weekend will be in the lower to mid 80s. A wave of low pressure may form to our SW on Monday and pass through Tuesday and Wednesday. This will allow for a prolonged period of south to southwest flow, which will allow additional moisture to stream into the area. This will result in showers and thunderstorms to develop, with the best coverage during the afternoon and evening hours. For temperatures, highs will remain in the low to mid 80s with low temperatures in the mid 60s to lower 70s. && .AVIATION /03Z THURSDAY THROUGH MONDAY/... A rather broad pre-frontal trough across southern New England and into the mid Atlantic states will move slowly east overnight. A cold front then moves through the area Thursday. Scattered showers and maybe an isolated thunderstorm will be possible through most of the overnight hours. Mainly VFR, except in areas of showers and isolated thunderstorms where MVFR is possible. There may be areas of MVFR fog and stratus as winds become light and variable, and continue to forecast this at KSWF and KISP, although there is uncertainty if this will occur. Light S-SW winds become westerly after 05Z as the pre-frontal trough moves through the terminals. Some outlying terminals may become light and variable. West to northwest winds will remain through Thursday, and increase up to 15 KT. Occasional higher gusts, up to 20 KT, will be possible, especially in the afternoon. .OUTLOOK FOR 00Z FRIDAY THROUGH MONDAY... .Friday-Friday night...VFR. Isolated thunderstorms possible late in the day and at night with local MVFR conditions. .Saturday through Monday...Chance of showers/thunderstorms with MVFR or lower conditions possible. && .MARINE... A weak frontal sys approaches tngt and passes on Thu. Although winds and seas will remain blw sca lvls, tstms will be capable of producing winds in excess of 35 kt, lightning strikes and torrential rain reducing vis. Winds and seas remain blw sca lvls Thu ngt. The pressure gradient remains weak overall through the weekend and into early next week, resulting in sub-SCA conditions through Monday. && .HYDROLOGY... While basin average rainfall amounts through Thursday are progged to remain less than one half inch, any thunderstorms will be capable of producing locally heavy rainfall and minor urban flooding, along with isolated flash flooding. Thereafter, showers or thunderstorms over the weekend and into the beginning of the week could produce locally heavy rainfall and minor urban flooding. && .TIDES/COASTAL FLOODING... Astronomical tides will be increasing with the approach of a new moon on Saturday. Coastal flooding will be possible with the evening/nighttime high tide cycles Thursday through at least Saturday. Although winds will be light, all that is needed in most cases is around half foot or less of tidal departures to reach minor coastal flooding. Areas that will be most susceptible to minor flooding during this period are the south shore back bays of Nassau, Queens and Brooklyn, Lower NY Harbor, and portions of western Long Island Sound and perhaps along Great South Bay in western Suffolk County. Minor flooding would be most likely during Friday and Saturday night. && .EQUIPMENT... NYC NOAA Weather Radio Station KWO-35 (162.55 MHz) remains off the air for an extended period of time. && .OKX WATCHES/WARNINGS/ADVISORIES... CT...None. NY...None. NJ...None. MARINE...None. &&
