| Area Forecast Discussion National Weather Service Buffalo NY 203am EDT Sat Oct 10 2026 .WHAT HAS CHANGED... Increased downsloping winds west of the Chautauqua Ridge ahead of the remnants of Hurricane Isaias.. .KEY MESSAGES... 1) The remnants of Hurricane Isaias will initially bring some gusty downsloping winds off the Chautauqua Ridge and then a soaking rain to the region tonight through Monday morning. KEY MESSAGE 1...The remnants of Hurricane Isaias will initially bring some gusty downsloping winds off the Chautauqua Ridge and then a soaking rain to the region tonight through Monday morning. Ridging at the surface and aloft will gradually exit east across western and north central New York as the remnants of Hurricane of Isaias becomes vertically-stacked as it passes through the trough aloft into the mid-Atlantic Seaboard region. Isolated rain showers will be possible after midnight tonight, especially across the western Southern Tier, due to moist isentropic lift aloft generated by the low pressure system. Additionally tonight ahead of the surface low, southeast winds across the Chautauqua Ridge will support increased downslope flow across the I-90 corridor of Chautauqua county. Wind gusts will gust up to 35 and 40 mph. Heading into Sunday, the low will pass northeastward from the lower Ohio Valley toward the central Appalachians, while the trough axis nears the forecast area, supporting widespread steady rain (heavy at times), to overspread the region from south to north as isentropic lift aloft continues across the region and taps into the plume of moisture originating from the southern Gulf Stream. The trough axis aloft will then pass from the Great Lakes to the Appalachians and further toward the Canadian Maritimes Sunday night through Monday. Meanwhile the vertically stacked surface low will dissipate over the Ohio Valley Sunday, while a new surface low develops over the Delmarva Peninsula and deepen while moving northeastward toward southern New England Monday. Additionally Monday, a surface ridge of high pressure will build across the eastern Great Lakes. Overall this will act to taper the rain from west to east Sunday night into early Monday morning, with predominantly dry weather expected for the remainder of Monday. Current forecasted rainfall amounts for Sunday through Sunday night range from a half of an inch to near three-quarters of an inch, with the higher amounts occurring across southern New York. Marine A high pressure ridge will cross the region today. Variable winds around 5 to 15 knots will persist on both lakes today with waves diminishing to below 3 feet. Southeast winds across the Chautauqua Ridge tonight into Sunday morning will support increased downslope flow, causing wind gusts of up to 30 knots for the nearshore waters of Lake Erie bordering Chautauqua County (Ripley to Silver Creek), where though winds and waves will be offshore, Small Craft conditions will be possible for a few hours. A trough axis will sweep east across both lakes Sunday night causing southeasterly winds to shift easterly before backing to northerly. The northerly winds will then back southwesterly on Monday as a ridge axis passes across the region. Winds of 5 to 15 knots and waves of 3 feet or less should persist. Southwesterly winds will then freshen to around 10 to 20 knots on the backside of the ridge axis Monday night and then veer to northwesterly on Tuesday as a cold front passes southeast across eastern Lake Erie and Lake America. Waves will build to as large as 3 to 6 feet where another Small Craft Advisory will likely be needed. In the wake of the front Tuesday night and Wednesday, winds will shift from northwesterly to northeasterly and gradually east to 5 to 15 knots as a high pressure ridge builds from northern Ontario province. Waves should subside gradually to 3 feet or less. NOAA Buffalo NY Office: Watches - Warnings - Advisories NY...None. Marine None. |
