| Area Forecast Discussion National Weather Service Buffalo NY 614am EDT Wednesday May 27 2026 .WHAT HAS CHANGED... No significant changes have been made to the forecast. .KEY MESSAGES... 1) Continued above normal temperatures today will trend somewhat cooler on Thursday, with a few widely scattered showers possible later tonight and Thursday. 2) A stronger cold front will move south across the area late Friday through early Saturday with a few showers possible, followed by below average temperatures for the weekend. KEY MESSAGE 1...Continued above normal temperatures today will trend somewhat cooler on Thursday, with a few widely scattered showers possible later tonight and Thursday. Today through Thursday mid-level troughing over Ontario and Quebec will sharpen and pivot southeastward across the Lower Great Lakes and New England. This feature will push a weak cold front across the area between this morning and early this afternoon...with an attendant dearth of moisture and upper-level support likely resulting in most if not all areas remaining dry. While some slightly cooler air will begin to arrive following the passage of the front...850 mb temps will still range from +8C to +10C across the North Country to +13C to +14C across the Southern Tier this afternoon...with both this and increasing sunshine/good mixing allowing for one more day of above normal temperatures. The main axis of the mid-level trough and associated shortwave energy will then make its way southeastward across the area later tonight and Thursday morning...with an attendant increase in lift and moisture bringing a somewhat better potential for a few widely scattered showers...particularly later tonight/early Thursday south of Lake Ontario. At the same time an associated pool of notably cooler air aloft overspread our region...with 850 mb temps falling into the +3C to +5C range Thursday morning...before rebounding slightly later in the day. Consequently...we can expect high temps to settle back to somewhat below average levels on Thursday...when daytime highs will range through the 60s. KEY MESSAGE 2...A stronger cold front will move south across the area late Friday through early Saturday with a few showers possible, followed by below average temperatures for the weekend. A deep...but fairly quick-moving closed low still looks to drop southeastward across Quebec on Friday...before crossing New England Friday night and Saturday. This feature will push its attendant cold front across our region sometime between later Friday and Friday night...resulting in near-normal temps Friday giving way to another shot of cooler air and somewhat below normal temps for the weekend...particularly on Saturday when temps aloft will be coolest. The passage of the front may also generate some scattered showers... with this potential greatest across the North Country/central NY where moisture and forcing both look to be a bit more favorable. Marine A weak cold front will sag southeastward across the Lower Great Lakes this morning...with southwesterly winds of 10-15 knots out ahead of the front becoming westerly/northwesterly and diminishing to 10 knots or less following its passage. Winds will then veer to northerly and increase somewhat tonight through Thursday morning with a light chop developing on both lakes. A stronger cold front will then push southeast across the region late Friday and/or Friday night...with low-end SCA (Small Craft Advisory) conditions possible both out ahead of and behind this boundary.
