Buffalo, N.Y. – Western New York will see another sweltering day Tuesday, with heat index values potentially reaching dangerous levels before a cold front moves in with thunderstorms. Highs will top out near 95°F in lower elevations across the Lake Plain, Genesee Valley, and northern Finger Lakes, with slightly cooler readings in higher terrain.
According to the National Weather Service in Buffalo, humidity will rise quickly through the day Tuesday, driving heat index values into the mid-to-upper 90s in some areas. Isolated afternoon showers and storms are possible, but the main line of scattered thunderstorms is expected Tuesday night into Wednesday as the cold front arrives.
The storms could bring heavy downpours, gusty winds, and brief localized flooding, particularly in low-lying and poor-drainage areas. Commuters should be alert for slick roads and reduced visibility. Residents are advised to stay hydrated, limit outdoor activity during peak afternoon heat, and secure outdoor items ahead of storms.
Temperatures will cool by midweek, with highs in the low 80s Wednesday and upper 70s to mid-80s Thursday under sunny skies. Additional weather statements may be issued if severe storm potential increases.
