691 FXUS61 KBGM 021832 AFDBGM Area Forecast Discussion National Weather Service Binghamton NY 132 PM EST Sun Nov 2 2025 .SYNOPSIS... Dry high pressure system remains in place into Monday morning. A weak front will pass through Monday afternoon with increasing winds into Monday night. Most of the area will remain dry with this frontal passage but winds remain gusty through Tuesday. Unsettled weather returns mid week into late week with better chances of precipitation. && .NEAR TERM /THROUGH MONDAY/... Surface high pressure builds in early this morning with much calmer winds. Clouds will scatter out later in the morning as dry air works its way to the surface with day time heating. With a trough to the west, 850 mb winds strengthen out of the south with some warming so once the sun is out, temperatures will warm into the 50s. Warm air advection increases tonight as several 500 mb shortwaves pass through with a strong lobe of vorticity well to the south and another weaker lobe dropping into the Great Lakes. The southern love of vorticity will block most moisture from advecting northward so conditions look dry through Monday evening. Areas along and north of I-90 and west of Rome NY may see a few rain showers late as Lake Ontario may provide just enough low level moisture to get a few rain showers to develop along a cold front moving in. A tightening pressure gradient with the approach of the northern shortwave will see winds increase through the day Monday. With 850 winds rising to 40 to 50 knots and cold air advection Monday afternoon helps to steepen the low level lapse rates, gusts across the region could approach 40 mph again. && .SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY/... The week starts off breezy as a shortwave passes through the Northeast. 850 mb winds remain 40 to 50 knots all of Monday night and into the first half of Tuesday. Winds were increased for overnight and through Tuesday with cold air advection helping to keep the low level lapse rates steep through the night then day time heating Tuesday helps with deeper mixing later in the day. Chances of precipitation will remain constrained to near and just downwind the Great Lakes with the limited moisture in place. Zonal flow takes over Tuesday night through Wednesday with warm air advection developing. Rain chances return Wednesday as the warm air advection leads to frontogenesis and a surface low developing in the Great Lakes region. High pressure moving off the Mid Atlantic coast helps open up the Gulf a bit with some better moisture advection late Tuesday night through Wednesday. && .LONG TERM /WEDNESDAY NIGHT THROUGH SATURDAY/... The long term will have mostly zonal flow though there will be plenty of shortwaves in the flow that move through mid to late week. Given that all these shortwaves are clipper systems, their timing is going to be tough to pin down so chances of rain showers were kept through much of the long term. High pressure remains off of the SE US coast so there will be available moisture for any passing system to work with. While snow looks unlikely right now, ensembles are starting to favor greater odds of cold air later in the week. Chances are greater than 50% of -5C 850 mb temperatures Thursday so freezing levels may get low enough for any lake effect to start to have a change over to snow at times. && .AVIATION /18Z SUNDAY THROUGH FRIDAY/... Mainly VFR conditions are expected over the next 24 hours. Clouds will be increasing and ceilings lowering by late tomorrow morning as showers approach, but any rain is expected to hold off until around or just after 18Z. Winds are expected to be rather light until late tomorrow morning when south to southwesterly winds start to gust around 20 knots. There is the potential for some borderline southwesterly LLWS early tomorrow, generally between 10Z-15Z at the NY terminals, especially around RME and SYR, so this may be included in future forecasts if confidence increases. The chance for any low clouds or fog overnight and early tomorrow morning looks to be low with model soundings showing increasing winds just above the surface during this time which would hinder any fog formation. Outlook... Monday afternoon through Monday night...Rain showers likely and associated restrictions, especially at the Central NY terminals. Tuesday through Wednesday...Mainly VFR. Wednesday night...Rain showers becoming likely and associated restrictions, especially at the Central NY terminals. Thursday...Some lingering restrictions possible at the Central NY terminals; otherwise becoming mainly VFR. Friday...Mainly VFR. Some showers possible and associated restrictions late in the day or at night. && .BGM WATCHES/WARNINGS/ADVISORIES... PA...None. NY...None. && $$ SYNOPSIS...AJG NEAR TERM...AJG SHORT TERM...AJG LONG TERM...AJG AVIATION...DK
