982 FXUS61 KBGM 011039 AFDBGM Area Forecast Discussion National Weather Service Binghamton NY 639 AM EDT Mon Sep 1 2025 .SYNOPSIS... High pressure will allow dry conditions and comfortable temperatures to persist through midweek. A cold front moves through Thursday into early Friday, bringing cooler temperatures as we head into next weekend. && .DISCUSSION... 245 AM Update... Surface high pressure will keep conditions dry through the midweek. Above the surface, weak area of low pressure with easterly flow may allow for mid-level clouds to develop Tuesday, though precipitation is not expected for majority of areas. There could be a light shower or two for northern portions of Central NY, but chances aren`t high. By Wednesday we get into return flow on the back side of the surface high, and flattening to southwesterly flow aloft. That in addition to sunshine, especially in the first half of the day, may get some of our lower elevations to eclipse 80 degrees. Meanwhile, in the Upper Midwest/Western Great Lakes a upper trough will be digging in out of the Canada, cutting off a deep upper low. An amplified pattern like this tends to progress slower than models initially indicate, and thus it is not surprising to see rain chances continuing to delay. That said, high confidence exists that this system will bring moisture out ahead of it and eventual rain for our region in the later Thursday to early Friday timeframe. Elevated precipitable water values, and deep moisture with near unidirectional south- southwest flow with a moist-adiabatic look to model soundings, point to at least a little potential for heavy rain. After 70s-near 80 Thursday, cold air advection in the wake of the front is forecast to dip that range to more like mid 60s-mid 70s Friday-Saturday. The somewhat cooler air may be coming more from a west-southwest direction initially and thus post-frontal lake effect showers and clouds may be pretty limited. That said, a renewed shot of chilly air may drop in from the northwest during the second half of the weekend for another notch down in temperatures. && .AVIATION /12Z MONDAY THROUGH FRIDAY/... VFR conditions expected across all terminals today with partly sunny skies and light winds. Guidance is showing a chance for fog yet again at ELM tonight. Confidence in this is low as conditions have been very similar over the past several nights, with some nights producing IFR/LIFR fog and other nights staying VFR. It seems we will see a little more moisture work its way in today, with dewpoints tonight in the upper 40s vs the low to mid 40s we have seen over the past several nights. With the surface high centered just to our east, winds should become calm and stay calm through the night, which should allow at least patchy fog and IFR conditions later tonight. Extended LIFR restrictions due to fog remains possible but confidence is not high enough to include it in the TAF at this time. Outlook... Monday night...VFR Expected. Chance for valley fog at ELM late. Tuesday and Wednesday...VFR. Thursday and Thursday night...Restrictions possible with showers and thunderstorms moving into the region. Friday...Lingering showers possible, with associated restrictions. && .BGM WATCHES/WARNINGS/ADVISORIES... PA...None. NY...None. && $$ SYNOPSIS...KL DISCUSSION...KL AVIATION...JTC
