NWS Binghamton, NY wrote its last area forecast discussion before the first event at Aug 16, 2:10 PM EST, 38 minutes earlier.
Area Forecast Discussion National Weather Service Binghamton NY 310 PM EDT Fri Aug 16 2019 .SYNOPSIS... Scattered showers and storms expected through this weekend with warming temperatures into early next week. The weather will remain unsettled and warm through at least the middle of next week. && .NEAR TERM /THROUGH SATURDAY NIGHT/... 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 /18Z FRIDAY THROUGH WEDNESDAY/... Ceilings will remain BKN and MVFR/low-end VFR through this afternoon with scattered rain showers developing into scattered thunderstorms after 20Z. An upper wave moving through today will enhance the potential for a few strong TS with gusty winds and heavy downpours possible. Conditions are should dry out behind the convection later tonight, which may lead to low stratus between 700 and 2500 feet and patchy fog. If there is enough convective debris hanging around through the night into Sat morning, the potential for fog will go way down...and conditions will likely remain MVFR/VFR. At this time, leaning more toward clearing with eventual fog. Conditions improve through the morning hours...becoming VFR after 15-17Z. Winds will be light from the south around 5-10 kt through the forecast period with the exception of gusty and erratic winds near thunderstorms. Outlook... Saturday afternoon and 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 NEAR TERM...BJT SHORT TERM...MPK LONG TERM...MPK AVIATION...BJT
