NWS Binghamton, NY wrote its last area forecast discussion before the first event at Aug 16, 7:02 PM EST, 28 minutes earlier.
Area Forecast Discussion National Weather Service Binghamton NY 802 PM EDT Fri Aug 16 2019 .SYNOPSIS... Scattered showers and storms are expected through this weekend with warming temperatures. The weather will remain unsettled and warm through at least the middle of next week. && .NEAR TERM /THROUGH SATURDAY NIGHT/... 7 pm update... Lowered pops across south central NY and NEPA. Thunderstorms continue across the Finger Lakes. These will continue for a few more hours and lift northeast into the western Mohawk Valley. Damaging winds and flash flooding still possible this evening. 310 pm update... Main concerns in the near term remain focused around the scattered showers and thunderstorms and the potential for strong to possibly severe weather this evening and again late Saturday. Fast-moving upper level short wave currently positioned over OH/MI/Lake Erie will move through NY/PA this evening and interact with modest instability and deep layer shear to produce and enhance showers and thunderstorms across the region. Current radar loop shows fairly widespread rain showers with a few isolated thunderstorms across much of the region. There is a weak capping inversion around 10k ft that is being realized within the atmosphere and causing some of the convection to dissipate, or remain relatively immature. Satellite visible/infrared imagery showing a fair amount of convective debris overtaking the region...which is likely limiting the amt of instability. However, the short wave upstream will most likely be the triggering mechanism to enhance the strength of the convection into this evening. A few thunderstorms will become strong to possibly severe with the main threats being damaging winds and heavy downpours. The upper wave and resulting convection is expected to shift to the east tonight and allow for weak ridging during the overnight hours. This will allow for generally quiet weather conditions later tonight and into Saturday morning. Some clearing of the skies is possible...which will lead to favorable conditions for patchy fog tonight. Conditions improve through Saturday morning with fog lifting and mixing out by noon. Temperatures will warm into the upper 70s and lower to mid 80s by the afternoon...and with dew points in the upper 60s...sfc based instability will increase and allow for the development of more scattered showers and storms. The passage of another upper level short wave later in the day Saturday will allow for more enhancement of the convection into the evening hours. A few storms may become strong to severe. && .SHORT TERM /SUNDAY THROUGH MONDAY/... 3 PM update... Surface high pressure/ridging will remain over the region into the start of next week. Zonal flow aloft with multiple weak waves running through will give us a chance for showers and storms, but activity will be mostly focused near peak heating hours and into the evening. Heat and humidity will also be on the rise with moist return flow in the low levels. Heat indices climb into the low 90s Sunday afternoon and possibly heat advisory criteria into the upper 90s on Monday afternoon. && .LONG TERM /MONDAY NIGHT THROUGH FRIDAY/... 3 PM Update... Tuesday will be similar to Sunday and Monday with diurnal showers and storms and hot/humid conditions. Deep upper low/trough will dig across Ontario and the axis should be centered over the NE U.S by Wednesday night with an associated surface cold front pushing through. Showers and storms are expected with the front Wednesday into Thursday morning...but much drier and cooler conditions should prevail by Thursday night into Friday as strong surface high pressure builds in. Temperatures will still remain near normal and very pleasant...into the upper 70s and lower 80s...behind the front. && .AVIATION /00Z SATURDAY THROUGH WEDNESDAY/... 740 pm update... In general VFR continues through Saturday. SYR/RME should have MVFR conditions and maybe IFR vsbys in thunderstorms up to 03z. Rest of sites should miss the convection. Late tonight valley fog will form with MVFR possible at all but SYR/BGM. ELM could fall to IFR from 09 to 13z. Saturday mainly VFR with afternoon and evening convection again. It should stay scattered so did not include a TEMPO at this time. Winds will be light and variable tonight. Saturday south winds at 6 kts. Outlook... Saturday evening...MVFR to VFR conditions with scattered showers and TS possible. Sunday to Wednesday...Restrictions possible in showers and storms. && .BGM WATCHES/WARNINGS/ADVISORIES... PA...None. NY...None. && SYNOPSIS...BJT/TAC NEAR TERM...BJT/TAC SHORT TERM...MPK LONG TERM...MPK AVIATION...TAC
