Scattered showers are possible Thursday morning with a few thunderstorms moving through in the afternoon and evening. Heavy downpours and damaging winds are possible. Temperatures will top out in the 70s, 60s in the North Country.
Friday will be quieter but there is a chance for a couple of more isolated showers and thunderstorms. Humidity will be rising, feeling almost tropical on Saturday.
Temperatures will top out in the low 80s on Friday and mid to upper 80s on Saturday. Highs in the 90s are expected from Sunday onward. A heatwave in NYS is defined as 3 or more days at or above 90°… so this will definitely be a late-spring heatwave for CNY. High humidity and plentiful sunshine are expected during this time.
