| Area Forecast Discussion National Weather Service Buffalo NY 209am EDT Thu September 10 2026 .WHAT HAS CHANGED... Minor changes with this forecast update. .KEY MESSAGES... 1) Drier and cooler weather will return for the end of the work week. 2) Warmer weather combined with increasing humidity will support the chance of showers and thunderstorms beginning Saturday. KEY MESSAGE 1...Drier and cooler weather will return for the end of the work week. An upper level trough will move across northern Ontario and Quebec today. A few boundaries will move across the region this morning, starting with a surface cold front associated with a deep area of low pressure over Hudson Bay. Behind the front, west-southwest winds will veer to the northwest, and drier air will filter into the region. An isolated shower early this morning along the front cannot be ruled out. The second frontal boundary is an 850mb thermal gradient north of the region this morning. Supported by a 150 knot 250 mb jet, a narrow line of showers has developed near Lake Huron. As this region moves away from the upper level support and encounters drier air, showers are expected to weaken as they move into western NY. Surface high pressure over the Midwest will build toward the eastern Great Lakes region today. A progressive shortwave trough is expected to meet with a frontal boundary south of the region this afternoon. An isolated shower is possible across the western Southern Tier. The surface high will settle across the region through the end of the work week bringing cooler, dry weather. KEY MESSAGE 2...Warmer weather combined with increasing humidity will support the chance of showers and thunderstorms beginning Saturday. A southerly flow will transport warm, moist air into the region Saturday. Diurnally-driven showers and thunderstorms are possible especially across western NY. An upper level trough and cold front may move across the region Sunday. Showers and thunderstorms are possible, however confidence is low on timing and strength at this time. Marine West-southwest winds will weaken on the eastern end of Lake Erie and Lake Ontario early this morning before increasing out of the west- northwest after daybreak. Winds will fall below small craft thresholds on Lake Erie and the advisory is expected to expire by 8AM. West-northwest winds 15 to 25 knots are expected on the east end of Lake Ontario through this evening. West winds 15-20 knots expected along the southern Lake Ontario shoreline. Small Craft Advisories will remain in effect across Lake Ontario. Surface high pressure will build across the region tonight and winds and waves will weaken. Light winds and waves will continue on the Lakes through Friday night. South-southwest winds will increase on the Lakes this weekend, however small crafts are not expected.
