554 FXUS61 KBGM 192350 AFDBGM Area Forecast Discussion National Weather Service Binghamton NY 750 PM EDT Tue Aug 19 2025 .SYNOPSIS... After dry conditions today, a widespread rainfall is expected to move into the area tonight into Wednesday. Conditions gradually dry out, with a warming trend for the end of the work week into the first half of the weekend. Showers and thunderstorms return to the forecast on Sunday, especially during the afternoon. && .DISCUSSION... .SHORT TERM /THROUGH FRIDAY NIGHT/... 235 PM Update: After mainly dry weather today, widespread rain showers will move into the region tonight ahead of an approaching shortwave. Rainfall amounts between 0.25 to 1 inch are expected across Central NY by daybreak Wednesday morning, with lesser amounts up to a tenth of an inch for Northeast PA by daybreak. Lows are expected to be in the 50s. Periods of rain and a few embedded thunderstorms will continue through much of the day Wednesday as the aforementioned shortwave moves through the area. An additional 0.25 to 1 inch of rain is expected on Wednesday areawide. A cool east- southeast wind combines with the clouds and showers to keep temperatures between the upper 50s to upper 60s all day, except perhaps lower 70s for the Chemung and Wyoming Valleys. While the rain will be moderate to locally heavy at times, flooding is not expected due to the dry antecedent conditions. A few lingering showers or drizzle is expected Wednesday night with the frontal boundary nearly stalled to the south. Lows Wednesday night are expected to be in the upper 40s to upper 50s. The weak lingering stationary front could still be located just south of the area on Thursday due to the presence of Hurricane Erin off of the Carolina/Mid-Atlantic coast. This weak boundary looks to keep more clouds in place from the Twin Tiers south across Northeast PA, along with isolated shower chances. Further north, skies are forecast to become partly sunny toward the I-90 corridor, and therefore temperatures will be slightly warmer across the northern portion of the area. High temperatures in the 70s are expected for most of the area. High pressure moves into the region Thursday night into Friday, which will result in a return to clear skies. Temperatures on Friday will be a bit warmer with highs in the mid 70s to lower 80s with plenty of sunshine. .LONG TERM /SATURDAY THROUGH TUESDAY/... 235 PM Update: Dry weather continues on Saturday, although a few showers cannot be ruled out west of I-81 towards the Finger Lakes Region ahead of the next approaching system. Highs on Saturday are expected to be in the upper 70s to mid 80s under mostly sunny skies, although some higher clouds will increase later in the day. A deepening longwave trough across Canada will bring a cold front through the area on Sunday. This will being scattered showers and thunderstorms to the area, especially during the afternoon. While coverage of showers will decrease Monday and Tuesday, our region will remain underneath this trough, which may allow for some additional isolated showers. Otherwise, the beginning of next week looks cooler with highs in the upper 60s and 70s. && .AVIATION /00Z WEDNESDAY THROUGH SUNDAY/... VFR conditions are expected through 6Z at all terminals. There is a small chance that rain could lower cigs to MVFR at SYR and RME before 6Z as rain is already moving in but will have to overcome a deep layer of dry air first. Heavier rain moves in between 6Z and 12Z bringing widespread restrictions to all terminals. IFR was reduced at AVP and ITH with the SE winds likely downsloping and keeping cigs above IFR outside of brief periods. Thunder is unlikely given the time of the day the rain showers move in and not much instability present. Most of the day tomorrow will have the rain and MVFR to IFR cigs sticking around. As the winds lighten up in the afternoon and evening, IFR cigs will be likely at all terminals by 0Z. Outlook... Thursday...Mainly VFR. Slight chance for a shower. Friday...Mainly VFR. Saturday...Mainly VFR. Low chance for showers and thunderstorms Saturday night. Sunday...Scattered showers and thunderstorms may bring occasional restrictions. && .BGM WATCHES/WARNINGS/ADVISORIES...
