There is a Marginal Risk of severe weather (1 out of 5) and a Marginal Risk of Excessive Rainfall (1 out of 4) this afternoon into early this evening. A few stronger storms may bring the threat for strong winds and heavy rainfall that may result in isolated flash flooding.
High temperatures across the lower elevations will be in the mid and upper 80s. The combination of heat and humidity will yield heat indices in the upper 80s to low 90s across the lower elevations, and possibly approaching the mid 90s across a few areas just south of Lake Ontario, and the western Finger Lakes/lower Genesee Valley.
Mainly dry weather expected through midday. The potential for showers and thunderstorms will increase starting this afternoon and continue into Friday. Mostly dry weather returns for the weekend. Very warm and humid today, then cooler behind a passing cold front.
