ROCHESTER, N.Y. – A Yellow Alert is in effect for Sunday, as a sharp cold front is expected to pack a quick punch across Western New York. Mostly sunny skies will stick around for a majority of the day before storms make their way in after 4 p.m. Main threats include gusty winds and hail. A smaller threat does exist for a weak spin-up tornado, however, that threat is mainly geared towards areas west and south of Monroe County. If these storms are held off until 7-8 p.m., this will be after the sun goes down which may play in our favor in limiting the energy of these storms. Nonetheless, expect a few of these storms could turn severe and have your First Alert Weather app downloaded on your mobile device to receive updates on severe weather in the area.
