107 FXUS61 KBGM 011805 AFDBGM Area Forecast Discussion National Weather Service Binghamton NY 205 PM EDT Sat Nov 1 2025 .SYNOPSIS... As winds and lake effect rain showers dissipate this evening, dry high pressure takes over for the remainder of the weekend. A weak front will pass through Monday afternoon and evening, generating some rain showers, mainly in Central New York yet with light amounts. In this unsettled pattern, additional weak systems may cause occasional chances of showers later in the week. && .NEAR TERM /THROUGH SUNDAY NIGHT/... Dry high pressure takes charge for the rest of this weekend. Though winds have diminished, for now we still have gusts frequently in the 15-20 mph range from a lingering pressure gradient under cyclonic west-northwest flow. With 850mb a few degrees below zero Celsius, a minor lake response has continued into this afternoon though all in the form of rain showers considering temperatures mainly in the 40s. Gradient will further relax as surface high pressure starts to build in tonight, and ridging aloft causes moisture to become very shallow overnight with no more precipitation. Lows will be generally upper 20s to mid 30s. What remains of trapped lake moisture may take some time to break up along the NY Thruway counties, but otherwise high pressure will result in mostly sunny conditions for Northeast PA to Finger Lakes-Southern Tier-Catskills NY, followed by a clear sky Sunday night. Near normal highs of upper 40s-upper 50s will be followed by lows of mainly upper 20s-upper 30s. && .SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/... While some showers are anticipated with a frontal passage Monday afternoon-evening, no high impact weather is foreseen. After high pressure scoots east Sunday night, we get into a temporary moderating return flow initially Monday, lifting temperatures into mid 50s-lower 60s for highs. That said, this will be ahead of an approaching weak cold front. Moisture will be fairly limited with this front, and so while some showers and clouds will encroach from the northwest the afternoon- evening, actual rain will be quite light and probably limited to Central New York. Spotty post-frontal showers could linger into early Tuesday morning downwind of Lake Ontario, but with lows of mid 30s-near 40 still not figuring on any real impacts. Ridging sneaks back into the region for the remainder of Tuesday-Tuesday night, extending from high pressure centered over the Southern Appalachians. This will give another window of dry conditions with highs mainly in the 50s, and lows mainly 30s to near 40. && .LONG TERM /WEDNESDAY THROUGH FRIDAY/... We remain in a busy pattern in terms of frequency of waves or disturbances, and yet none of it likely to be impactful. A wavy westerly zonal flow will persist across the northern U.S. during mid-to-late weak. Associated embedded waves appear fairly weak and thus there is uncertainty in the timing of each. Also, despite shifting winds, none of the waves appear to be gusty beyond what would be typical for this time of year. For now the better rain chances are with a passage late Wednesday-early Thursday, and another around late Friday- early next Saturday. Cannot totally rule out wet post- frontal snowflakes in higher terrain as the 540dm 1000-500mb thickness line weaves back and forth across the region, but again nothing of real consequence figured at this time. Despite day-to-day changes, overall temperatures wash out somewhere around normal for early November. && .AVIATION /18Z SATURDAY THROUGH THURSDAY/... Lake clouds will remain overhead the Central NY terminals but conditions should be VFR throughout the next 24 hours. There is a slight chance for drizzle or light rain at SYR through the evening hours. There is low confidence that fog will develop in the valleys and impact ELM. Little to no guidance has it but clearing skies, light winds, and moisture from rain yesterday could lead to fog developing. The one uncertainty is cloud cover as mentioned previously, lake clouds linger overnight. Also, with plants becoming dormant, fog becomes less favorable. Winds are still quite gusty this afternoon as observed gusts have been 25+ kts. Those higher gusts are expected through the afternoon at all terminals but become lighter this evening. Around 00z, winds will become light and variable. Outlook... Sunday...Mainly VFR conditions expected. Monday Through Thursday..Chance for periods of rain showers and associated restrictions, especially for Central NY terminals. && .BGM WATCHES/WARNINGS/ADVISORIES... PA...None. NY...None. && $$ SYNOPSIS...MDP NEAR TERM...MDP SHORT TERM...MDP LONG TERM...MDP AVIATION...BTL
