A flood watch has been issued for all of Western New York for this evening through late Monday afternoon.
Heavier rain will begin after midnight, according to Bill Hibbert, a meteorologist with the National Weather Service office in Buffalo. Buffalo could see up to 2 inches of rain, while 2 1/2 inches could fall in the western Southern Tier.
“Tonight we are expecting quite a rain event,” Hibbert said. “We worry about hillier terrain areas prone to flooding such as Gowanda, Silver Creek and Arcade.”
Tuesday and Wednesday will be cooler, with highs forecast between the mid-60s and 70 and a slight chance of a shower. Hibbert said there could be some fall-like, lake-effect rain showers Tuesday. Waterspouts on Lake Erie and Lake Ontario are even possible with the unseasonable conditions.
Temperatures will return to the upper 70s and lower 80s by the end of the week, Hibbert said, with mostly dry conditions.
