The combination of rain with melting snow caused by unseasonably warm temperatures is a recipe that may cause flooding in some areas of Western New York.
The National Weather Service put a flood watch into effect for Erie, Chautauqua, Cattaraugus, Allegany and Wyoming counties at 7 a.m. It runs through Friday night for Erie and Wyoming counties and Saturday morning for Allegany, Cattaraugus and Chautauqua counties. With more than an inch of rain possible, the waters of area creeks and streams will be rising.
The Allegheny River in Cattaraugus County is under a flood warning, expected to reach flood stage tonight. It is expected to crest early Friday morning, the weather service said.
So here's how forecasters see the next 36 hours:
The rain will stop but temperatures will continue to drop, with the thermometer approaching the freezing mark by about midnight. Overnight lows are expected to be in the mid to upper 20s.
No precipitation in the forecast with a high temperature expected of about 27 degrees.
There's a slight chance of snow showers before 11 p.m. The low is forecast to be around 19 degrees.
