| Area Forecast Discussion National Weather Service Buffalo NY 639am EDT Sunday May 31 2026 .WHAT HAS CHANGED... Increased Probability of Precipitation east of Lake Ontario for this afternoon and evening. .KEY MESSAGES... 1) Backdoor cold front to bring showers this afternoon and evening to the east. 2) Unsettled weather returns next weekend. KEY MESSAGE 1...Backdoor cold front to bring showers this afternoon and evening to the east. Our region will lie under an omega-blocking pattern...with the favorable ridge of pleasant weather just enough off to our west to allow a shortwave trough and its associated cold front to drop across the eastern Lake Ontario region, and towards the Finger Lakes this afternoon and evening. Instability is marginal for any thunder, but forcing along the front, combined with increase moisture with the shortwave trough should yield light showers that back in from the east this afternoon...and diminish over the Finger Lakes region this evening. Overall rainfall will average a tenth of an inch or less. KEY MESSAGE 2...Unsettled weather returns next weekend. As the omega pattern breaks down later this week, a shortwave trough from the west will bring back unsettled weather to our region. While a few members of the GEFS, GEPS and ENS bring in showers or thunderstorms on Friday, the higher percentage of these ensemble members favor the Saturday and Sunday timeframe...most notably the afternoon hours during peak heating of the day. Marine Surface high pressure over Lake Erie this morning will drift to the southeast...allowing for a backdoor cold front to clip Lake Ontario this afternoon and evening. Westerly flow will continue today, with winds weakening tonight and shifting to northerly behind the cold front. Early this afternoon waves may reach 2 to 3 feet along the eastern Lake Ontario shoreline before diminishing with weakening flow. This light northerly flow will continue through Monday as high pressure again builds back into our region. This high will anchor over the eastern Great Lakes through at least Thursday, spelling great conditions for boating this first week of June.
