I’m watching a warm and increasingly humid airmass settle in over the Finger Lakes tonight — and this pattern is going to dominate the week ahead. Light rain is already falling across Geneva, Canandaigua, and Penn Yan as of late tonight, with heavier showers reported around Auburn. Lows will only drop to the low 60s overnight, staying muggy with humidity values running well above 85% in many spots.
Wednesday brings a slight cooling break — highs in the upper 80s rather than the 90s we hit today — with a westerly flow developing and gusts to 20–25 mph possible. Don’t pack the umbrella away; scattered showers and thunderstorms are expected to continue through Friday.
The real story builds Thursday into Friday, when humidity surges again and heat indices could climb into the low-to-mid 90s. NWS forecasters in Buffalo are watching that window for possible heat headlines, though cloud cover and storms could keep the worst of it in check.
A cold front arrives this weekend, finally breaking the pattern and ushering in noticeably cooler and more comfortable conditions by Saturday.
