NWS Binghamton, NY wrote its last area forecast discussion before the first event at Aug 6, 2:15 PM EST, 1 hour 16 minutes earlier.
Area Forecast Discussion National Weather Service Binghamton NY 315 PM EDT Tue Aug 6 2024 .SYNOPSIS... Persistent rain in NY and scattered showers and storms in northeast PA will dominate the area this evening. A few storms could become severe and also produce heavy rain. By Wednesday, cooler temperatures will arrive for most areas. with drier air expected into Thursday before more rain chances Friday into the weekend. && .NEAR TERM /THROUGH WEDNESDAY NIGHT/... 315 PM update... Main concerns in the near term are focused on the potential for severe thunderstorms producing damaging winds, hail and heavy rain this afternoon and evening...mainly along and south of the NY/PA border. A Flash Flood Watch has been issued for the Wyoming Valley and the Poconos, and a Severe Thunderstorms Watch has also been issued for the same area, but including Wyoming County and northern Wayne County in northeast PA. A series of mid level short waves are expected to track east across the state of PA today and into tonight and will interact with an increasingly unstable air mass that contains a robust amount of deep moisture. Numerous discrete convective cells have already blossomed across PA in NJ as of 3 PM and a broken line of convection is tracking east across the Appalachian Mtns in w-central PA. There is also a second batch of thunderstorms to the west that will move through central PA later this evening. The main threat for severe thunderstorms will be damaging wind gusts, with secondary threats being hail and tornadoes. There is a corridor of 1000-2000 J/kg of ML CAPE along and south of I-80, but it really drops farther to the north. The more favorable deep layer shear profiles exist over western PA, and may come into play with the second round of convection. The second round may end up impacting areas farther to the south/sw of Scranton/W-B before we lose the diurnal heating and instability of the day. Before then...from 3-8 PM...is the window of opportunity for a few severe storms in ne PA. The training nature of these storms, along the east-west oriented quasi-stationary front across PA, will enhance the threat of heavy rain and flash flooding. PWs around 1.8 to 2 inches is more than sufficient for heavy rain, and unidirectional wind profiles and relatively tall, skinny CAPE soundings (and high freezing levels, 10- 12kft) are all favorable for training thunderstorms with mostly liquid water throughout the column. Rainfall rates in some of the heaviest downpours could approach 1-1.5 inches per hour...which would be very hazardous for the steep terrain of the Poconos and the urban areas of the Wyoming Valley. Drier air will begin to push slowly in the area tonight and Wed morning from the northwest. A few lingering rain showers will hold on east of I-81 through sunrise, and it will take a bit longer to clear out cloud cover...but the overall trend will be to dry conditions out later in the day. Some patchy fog and low clouds will develop tonight and dot the area through the mid morning hours before lifting and mixing out. Temperatures will be noticeably cooler than relative history with highs only topping out in the 70s and dew points in the 50s and lower 60s. A dry northeast wind around 5 to 10 mph will make it feel a bit more like fall. Another round of cooler overnight temperatures will occur Wed night with lows bottoming out in the 50s. The threat for fog will be higher, especially where it clears out and in the valley locations. && .SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/... 300 PM Update... Surface high over the northern portion of the region slides to our east Thursday. Southerly flow sets up aloft ahead of an upper level trough advecting tropical moisture into our region. This leads to scattered showers kicking off Thursday afternoon mainly over northeast PA and the southern Catskills. Highs are expected to range in the 70s during the afternoon with lows ranging in the upper 50s to low 60s at night. Upper level trough settles in northwest of the Great Lakes Thursday night into Friday enhancing southerly flow leading to strong moisture advection. As a result rain showers are expected to continue into the overnight period with increasing PWATs. Similar pattern continues into Friday with moisture continuing to push into our region. Remnants of Debby will continue to track north throughout the day eventually getting pulled into the upper level trough moving east. PWAT values range 2-3 standard deviations above average Friday afternoon through the evening suggesting heavy rainfall will be possible. There is still uncertainty where the heaviest rain will set up but models have shifted west with this update with a slight uptick in rain totals. WPC has kept our region in a slight risk for excessive rainfall Friday through Friday night. Heavy rain combined with saturated soils from recent rainfall events increases flooding concern over our region. && .LONG TERM /SATURDAY THROUGH TUESDAY/... 300 PM Update... Frontal system along with upper level trough pushes this system east sometime Saturday. GFS holds onto the rain longer, but system should exit by Saturday evening. Brief dry conditions follow Saturday night into Sunday morning before upper level low shifts east over the Great Lakes. This brings additional moisture to our region as the low rotates sending a few short waves to kick of spotty rain showers. This pattern continues through most of this period with diurnally driven showers expected through Tuesday. High temperatures will range in the 70s during the day with overnight lows in the 50s. && .AVIATION /18Z TUESDAY THROUGH SUNDAY/... A nearly stationary boundary and unstable conditions will allow more showers and thunderstorms to form this afternoon. The best chances for TS will be across ne PA. Confidence is still rather low but slightly higher for ELM and BGM, and even lower for ITH, SYR and RME. After the rain moves out this evening another round of low clouds and fog with, MVFR/fuel alternate required conditions later tonight and Wed morning. .Outlook... Wednesday afternoon through Thursday...Mainly VFR. Friday through Saturday...Chances for showers and thunderstorms increase with persistent and potentially heavy rain within low clouds and fog. Sunday...Conditions clear out on Sunday with mainly VFR conditions possible. && .BGM WATCHES/WARNINGS/ADVISORIES... PA...Flood Watch until 2 AM EDT Wednesday for PAZ044-047-048-072.
