Heavy Rainfall Risk Continues Thru Wednesday Night

Additional rounds of showers and thunderstorms will continue to bring mainly beneficial rains to portions of Western & North-Central NY through midweek. Higher rainfall amounts going forward are expected from the Genesee Valley eastward. Rounds of repeated heavy rainfall over the same areas may result in isolated instances of flash flooding.

Showers and thunderstorms continue tonight, with a focus upon eastern zones, where a few storms could still bring heavy downpours of rain. It will remain muggy tonight with overnight lows remaining in the 60s for most areas.

A very moist air mass overhead along with a slow-moving area of low pressure will support additional rounds of heavy rainfall into Wednesday night. Although mainly beneficial rains are expected, a Marginal Risk (Level 1 of 4) for Excessive Rainfall will persist tonight across the bulk of the area, then east of Lake Ontario Wednesday into Wednesday night.
