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 Binghamton, NY wrote its last area forecast discussion before this special weather statement went out at Aug 19, 3:02 PM EDT, 4 hours 11 minutes earlier.
Area forecast discussion, Aug 19, 3:02 PM EDT, 4 hours 11 minutes before
Area Forecast Discussion National Weather Service Binghamton NY 302 PM EDT Sat Aug 19 2017 .SYNOPSIS... An upper level disturbance will move across NY and PA this afternoon and evening bringing scattered showers and isolated thunderstorms to our area. After this disturbance passes by, high pressure will build into our region for Sunday and Monday with fair weather and seasonable temperatures. The next chance for precipitation will come Tuesday as a cold front approaches the region. && .NEAR TERM /THROUGH SUNDAY/... Scattered showers are developing across western NY and northwest Pennsylvania as weak capping indicated on the 12z Buffalo sounding begins to break down. Strongest storms are beginning to develop over eastern Ohio and these will track east-southeast across western Pa during the next few hours remaining well to our south and west. Latest HRRR and RAP forecasts continue to indicate only marginal levels of instability in our area with MLCAPE values maxing out near or just above 500 J/kg and the best chances for organized convection remaining to our south and west. We are expecting scattered showers with isolated thunder to move across our area during the mid afternoon through early evening followed by clearing overnight, then patchy low clouds and fog around daybreak Sunday. Sunday looks like a mostly sunny and seasonably warm day with highs in the mid 70s to lower 80s as high pressure builds across the area. && .SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY NIGHT/... 300 PM EDT Update... Minor changes were made to the previous forecast. Zonal flows will prevail over the region from Sunday night through Tuesday morning, combined with ridging at mid-lvls and surface high pressure. This combination will result in mostly sunny skies, above normal temperatures with no chance for precip. Temps Monday night will range in the mid 50s/low 60s. Temps Tues afternoon will rise into the mid/upper 80s and fall into the 60s Tues night. && .LONG TERM /WEDNESDAY THROUGH FRIDAY/... 300 PM EDT Update... Updated with new WPC guidance... Surface high pressure will slide off to the east early Tuesday morning as the next storm system approaches the region from the west. There continues to be fairly decent model agreement on the timing of the next system with showers moving into western NY as a sfc low moves NE into Quebec Tuesday night and a fropa moves across Ny/PA Tues night. Showers and thunderstorms are likely across the region late Tuesday evening into Tuesday night. This could be our next shot for a widespread rainfall event. The upper level shortwave that will force the sfc low/fropa across the region will be slow to move east, thus showers and and a possible rumble of thunder will be possible through Thursday. High pressure is expected to build back into the area Thurs evening. && .AVIATION /19Z SATURDAY THROUGH THURSDAY/... Scattered showers with isolated thunder will develop across the area this afternoon into this evening. A shower is possible at any of the TAF sites between 19z and 01z today and have included a tempo group at BGM/ELM/AVP for a showers where we believe the best chance for a shower will be. After 01z skies will become clear to partly cloudy with patches of low cloud and fog after 06z. Skies will become mostly sunny on Sunday with just scattered cu. Winds will be west at 10 to 15 kts with a few higher gusts this afternoon, northwest at less than 10 kts tonight and west at around 10 kts on Sunday. Outlook... Sunday through Monday...VFR. Possible IFR in valley fog early. Tuesday...Restrictions possible in thunderstorms. Wednesday...VFR. && .BGM WATCHES/WARNINGS/ADVISORIES... PA...None.
