Several rounds of showers and thunderstorms are expected this afternoon and tonight.
WXXI meteorologist Josh Nichols said some may be severe with heavy rain, damaging wind gusts and hail.
"And I wouldn't be shocked if there was an isolated tornado," he said.
Flash flooding is also a possibility, with more than an inch of rain expected in some spots.
Nichols said the expected time frame to watch for the bulk of the storms is between 7 p.m. and 1 a.m.
