NWS Binghamton, NY wrote its last area forecast discussion before the first event at Jun 5, 3:29 PM EST, 1 hour 1 minute earlier.
Area Forecast Discussion National Weather Service Binghamton NY 429 PM EDT Mon Jun 5 2017 .SYNOPSIS... Showers and storms this evening will subside tonight and redevelop Tuesday. The potential for overnight rain showers and afternoon showers and storms exists through the rest of the week before dry and warmer weather settles in this weekend. && .NEAR TERM /THROUGH TUESDAY NIGHT/... 350 pm update... Main concerns in the near term remain focused around the scattered showers and thunderstorms across the region the rest of today, the potential for patchy fog early Tuesday morning, and another round of showers and storms through the day Tuesday. There still exists a threat of strong to severe thunderstorms into the evening hours with hail and damaging winds the main concerns, along with localized flooding. Surface low over central NY with a stationary front draped west to east across the area remains the focus of convection this afternoon. An incoming upper s/w will rotate through the region later this afternoon and early this evening as well, and enhance the large scale lifting that will support further convective development. The presence of weak to modest instability (SB CAPE values around 1000 J/kg) and strong deep layer shear, will continue to create favorable conditions for a few more strong to possibly severe storms early this evening. There will also be residual deep layer moisture hanging around, enough to trigger heavy downpours on already saturated soils and create excessive runoff and localized flooding. The short wave will kick to the east tonight as a wedge of drier air advects in and allows most of the significant precip to stop. Will likely be a few light rain showers lingering across the ern counties with drier conditions to the west. May see a batch of fog develop over the wrn counties late tonight and Tue morning. The main upper low will drop in from the nw over w-central NY during the day Tuesday and cause the convective showers and storms to re- develop. Instability and deep layer shear will not be as intense, so not expecting thunderstorms to be as strong. Air mass will likely be a bit drier as well, so downpours not expected to be as heavy. Steering flow within the upper low will be rather weak, so storm motion will be very slow. So, even though deep moisture will not be available, scattered to isolated slow moving storms may cause issues. May see a quarter to a half inch of precip through the day. Upper low will slowly drift to the south Tuesday night and allow the showers and storms to end. Low temperatures tonight will fall into the lower to mid 50s. Highs on Tuesday will only reach into the lower to mid 60s from w-central NY into ne PA...and into the mid to upper 50s from the Tug Hill plateau into the Catskills. Lows Tuesday night will drop into the mid 40s to lower 50s. && .SHORT TERM /WEDNESDAY THROUGH THURSDAY/... 4 PM Update... Cutoff low dropping south into PA Wednesday. Elongated from northeast to southwest. Best forcing and rainfall will be well to the southwest of the cwa in western PA into the Ohio Valley. cold air aloft will keep some showers and clouds around this entire period. Low level flow will be from the southeast. Best chances of showers during the afternoon each day. Temperatures continue below normal with highs mid 60s to low 70s and lows in the 40s. && .LONG TERM /THURSDAY NIGHT THROUGH MONDAY/... 4 PM update... Warming and drying trend as an upper level trough over the area at start moves east then a ridge moves in Sunday and Monday. Temperatures start out below normal at the start then on Monday are about 10 degrees above normal. Highs near 70 rise into the 80s. Lows in the 40s rise to around 60. Weak waves drop into the back side of the trough into Saturday causing mostly light afternoon rain showers. && .AVIATION /20Z MONDAY THROUGH SATURDAY/... Showers and thunderstorms are developing over wrn /w-central NY and far nrn PA early this afternoon and will likely expand in coverage and intensity through 00Z. Flight conditions will range from VFR to MVFR in TS with brief gusty winds and locally heavy rain possible. Will likely see IFR restrictions later tonight with another round of rain showers by Tuesday morning and ceilings only improving to fuel alternate required or MVFR. Winds will remain light and variable through the forecast period. A gust to 30 kt or greater is possible if a thunderstorm impacts a terminal. Outlook... Tuesday night...Restrictions likely in rain showers. Wednesday-Thursday...Restrictions possible in morning fog, showers through the day...and afternoon thunderstorms. Friday...Restrictions possible in showers and storms. && .BGM WATCHES/WARNINGS/ADVISORIES... PA...None.
