| Area Forecast Discussion National Weather Service Buffalo NY 533am EDT Fri May 8 2026 .WHAT HAS CHANGED... Minor changes to the forecast with this update. .KEY MESSAGES... 1) Cool and unsettled weather will continue through Saturday morning with a few rounds of showers, along with rain free time. 2) Periods of unsettled and cool conditions to persist well into next week. KEY MESSAGE 1...Cool and unsettled weather will continue through Saturday morning with a few rounds of showers, along with rain free time. A series of shortwaves will continue to support rounds of showers across the region today through Saturday morning, but each round will be relatively brief with plenty of rain free time in the mix. The next mid level shortwave crossing Western NY early this morning will reach the Finger Lakes and Central NY later this morning. A brief period of DPVA and moisture convergence ahead of the shortwave will support a concentrated area of showers crossing Western NY early this morning, then the Finger Lakes and Central NY from mid morning through midday. Rainfall amounts will be light, generally less than 0.20". Subsidence and dry air in the wake of this shortwave will allow dry weather to return this afternoon. Cool air aloft will continue to support cu/stratocu development this afternoon inland from the lakes, with stable lake shadows allowing for more sunshine east of Lake Erie and Lake Ontario. Dry weather will prevail through this evening as a bubble of high pressure drifts east of the eastern Great Lakes. Overnight, a southern stream shortwave and upper level jet segment will allow a baroclinic wave to develop and track from the Ohio Valley into PA overnight. Thermal packing and increasing frontogenesis along and north of the baroclinic wave will bring another period of rain to the Southern Tier overnight through Saturday morning. The northern edge of this shield of rain will move into the Finger Lakes and Central NY for a few hours Saturday morning, but areas farther north and west should stay mainly dry, including the Buffalo, Rochester, and Watertown areas. KEY MESSAGE 2...Periods of unsettled and cool conditions to persist well into next week. The active weather pattern appears to continue through the weekend, and then likely well into next week. After some dry time Saturday afternoon the next chance for some showers arrives Saturday eve and then continues into Sunday as a wavy cold front slips through the region. A cool cyclonic flow will follow the front Monday, with a chance of some scattered showers as the trough crosses the region. A weak surface ridge moves over the region Tuesday with a brief period of dry weather ahead of the next upstream trough set to arrive Wednesday. Wet and continued cool conditions return Wednesday with continued chances for showers through the rest of the week as a deep trough resides across the eastern U.S. Marine Relatively light southwest winds today will become southerly and increase into the 10 to 15 knot range tonight through Saturday, with winds and waves remaining below Small Craft Advisory criteria. A cold front will then cross the lower Great Lakes Saturday night through Sunday. Southwest to west winds will increase with the passage of the front, especially on Lake Ontario. Wave action will become very choppy at a minimum, with a chance of low end Small Craft Advisory conditions at the east end of Lake Ontario later Saturday night through Sunday.
