A holiday weekend sends-off with pleasant conditions tonight. High pressure is moving overhead, which means clear skies, light northwest winds, and lows dropping into the mid-to-upper 50s regionwide — no frost concerns, but calm and cool enough for a comfortable night. The one thing to watch: that same high pressure and light wind setup could allow patchy fog to develop in valley areas, particularly around Watkins Glen and Canandaigua Lake’s lower elevations, before dawn Tuesday.
Tuesday itself looks like the pick of the short-term forecast. Expect mostly sunny skies and genuinely warm conditions, with highs climbing into the mid-to-upper 70s — Geneva and Ithaca could both touch 80°. Enjoy it while it lasts.
The pattern shifts Tuesday night as a cold front dropping south from Quebec brings the chance of showers and a thunderstorm. That unsettled stretch continues into Wednesday before quieter, cooler air arrives Thursday.
