Area Forecast Discussion National Weather Service Binghamton NY 408 PM EDT Thu Aug 15 2019 .SYNOPSIS... A weak frontal system with unstable air will track across NY and PA this afternoon and evening. Scattered showers and thunderstorms will continue into tonight. The weather will remain unsettled into the weekend. && .NEAR TERM /THROUGH FRIDAY NIGHT/... 3 pm update... A weak surface trough in eastern Ohio will move slowly east and weaken further tonight. A short wave will move through our area into tonight. In addition an upper level jet is on the east coast providing added lift. With surface heating today, cape has increased to 1500 in the far west and southwest. Deep shear in the same area is 40 kts. This area coincides with the better thunderstorm coverage and the slight chance of severe on the day 1 from the storm prediction center. In the northeast still stable and dry. Showers and thunderstorms will push northeast into tonight with the short wave. The slow movement of the thunderstorms has caused heavy rain to add up to 2 or 3 inches in Luzerne County with flooded roads. Will need to watch for training as more storms develop. pwats around 1.25" with slow movement this afternoon increasing tonight. Another short wave late tonight will increase the coverage across Syracuse and Utica. With the clouds and high dewpoints, low temperatures will be mostly in the low 60s. Friday will be similar with more showers and thunderstorms. Diurnal heating will help with the instability as temperatures rise to the upper 70s. Forcing will be weaker than today. Friday night showers and thunderstorms taper off with the lack of heating. Lows in the mid 60s. && .SHORT TERM /SATURDAY THROUGH SUNDAY/... 330 pm update... Main concerns in the short term remain focused on the persistent chance of showers and thunderstorms through the weekend with temperatures warming well above average. Large scale synoptic pattern will remain defined by weak cyclonic flow with embedded short waves rotating across the eastern Great Lakes and Northeast through the weekend. The first, slightly more amplified, wave will track e/ne through central NY on Saturday, and combine with modest instability to trigger more showers and thunderstorms in the afternoon and evening. Temperatures on Saturday will climb into the lower 80s with dew points in the upper 60s making it feel like the mid 80s. Conditions will be even hotter on Sunday with highs reaching into the mid to upper 80s...close to 90. The highest heat indices will be in the lower 90s along the lake plain of the nrn Finger Lakes and in the valley locations of the srn tier of NY and ne PA. A weaker wave rotates through on Sunday, but should still be able to combine with modest to high instability by the afternoon to generate more showers and thunderstorms. && .LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/... 330 pm update... A broad and relatively flat upper ridge will build across much of the eastern US Monday and Tuesday with continued warmth and slightly drier weather conditions likely. The overall flow pattern will be flat across the ern Great Lakes into nrn New England...so the increased heat and humidity will combine with weak ripples along the nrn periphery of the ridge to produce slight chances for thunderstorms both Monday and Tuesday afternoon/evening. An upper low over Hudson Bay will eventually rotate e/sewd by the middle of the week with a spoke of energy dropping south across the Great Lakes into the Northeast. This wave will have much cooler and drier air associated with it and likely interact with the warm and humid air mass in place to trigger showers and storms along and ahead of the front. Temperatures will still remain near normal and very pleasant...into the upper 70s and lower 80s...behind the front. && .AVIATION /20Z THURSDAY THROUGH TUESDAY/... 130 pm update... A scattered to broken cumulus deck with a base of 4000-6000 feet will be over the terminals into this evening. Showers and thunderstorms are developing near AVP/BGM/ELM and tracking slowly northeast. Brief restrictions are possible with stronger storms. This will move into the ITH area around 22z then to SYR/RME around 00z. Restrictions likely late tonight at all but SYR. Most restrictions will be due to cigs falling to MVFR but at ELM vsbys could also be MVFR. AVP/BGM should fall to fuel alternate MVFR 10 to 15z. All NY sites go to VFR by 16z. Light southeast winds at 5 kts this afternoon. Winds turn south late tonight. Outlook... Friday afternoon to Saturday...MVFR to VFR conditions with scattered showers possible. Sunday to Tuesday...Restrictions possible in rain showers. && .BGM WATCHES/WARNINGS/ADVISORIES... PA...None.
