| Area Forecast Discussion National Weather Service Buffalo NY 625am EDT Monday May 25 2026 .WHAT HAS CHANGED... No significant changes to the forecast. .KEY MESSAGES... 1) Rain exits the region this morning, with increasing sunshine this afternoon. 2) Turning much warmer for Tuesday and Wednesday with a few widely scattered showers or storms possible. 3) Mainly dry and seasonable weather Thursday through next weekend. KEY MESSAGE 1...Rain exits the region this morning, with increasing sunshine this afternoon. Northern and southern stream shortwave troughs, along with a weak area of low pressure, will move across Lake Erie and western NY this morning. A large swath of rain extending from the Mid-Atlantic region to north-central NY will move east through the morning hours. Showers are expected to taper off from west to east, exiting north- central NY by mid-morning. As the low moves overhead, light winds and very moist surface conditions will lead to patchy fog and low clouds this morning. Additional rainfall amounts of 0.15-0.35 inches are expected across the southern Tug Hill region, with less than 0.15 inches expected further west. While patchy fog and low clouds will linger through the morning, sunshine will increase from west to east this afternoon. Highs will reach the low to mid 70s for lower elevations and upper 60s for higher terrain. KEY MESSAGE 2...Turning much warmer for Tuesday and Wednesday with a few widely scattered showers or storms possible. Surface high pressure will slowly drift south across the eastern Great Lakes region Tuesday. Upper level ridging will remain overhead and mostly sunny skies will support temperatures in the upper 70s to low 80s. Southwest winds are expected to increase on the northern side of the departing high Tuesday. This will result in cooler temperatures near and downwind of the Lakes. A cold front associated with low pressure in northern Quebec is expected to move south across the forecast area Tuesday night through Wednesday night. A narrow corridor of modest moisture tied to the front may result in showers and a few thunderstorms, however precipitation coverage will depend on the timing of the front. Due to the uncertainty, the current forecast reflects a low chance of showers and thunderstorms for Wednesday afternoon. KEY MESSAGE 3...Mainly dry and seasonable weather Thursday through next weekend. Following the cold front on Wednesday, the pattern suggests a high- amplitude ridge across the CONUS' midsection and a reloading trough across the Northeast through next weekend. A large area of high pressure is expected to build across the region late in the work week and support seasonal temperatures and mostly dry weather. Forecast confidence lowers toward the end of the period, as mid-range model guidance indicates the potential for some unsettled weather on the weekend. Marine Light winds and more favorable boating conditions will return for Memorial Day Monday. Southwest winds freshen to 15 knots on Lake Ontario Tuesday through Tuesday night.
