A gorgeous May morning is unfolding across the Finger Lakes, with clear skies and temperatures in the mid-to-upper 40s as of 6 AM. Enjoy the quiet start — it won’t last all day.
By this afternoon, a mid-level shortwave pushing across the Ohio Valley will interact with peak heating to spark a few showers and thunderstorms, most likely between 2 and 7 PM. The threat for severe weather is low, but enough wind shear aloft — around 40 knots — means any storm that develops could produce gusty winds and brief heavy rain. Inland areas like Watkins Glen, Corning, and Bath carry the highest risk; lake-stabilized communities closer to the water may largely stay dry. Highs will be impressive regardless, reaching the upper 70s to near 81° in the southern valleys before storms arrive.
Skies clear overnight with lows settling back into the mid-to-upper 40s — comfortable sleeping weather.
Sunday looks mostly dry as high pressure builds, pushing highs back into the mid-70s. Then Monday and Tuesday, a strong ridge establishes over the eastern U.S. and temperatures surge into the mid-to-upper 80s region-wide, with a few lower-90s readings possible at typically warm spots like Penn Yan and Canandaigua. Some daily record highs could be within reach those days, though lower humidity should keep conditions manageable. Enjoy it while it lasts — the pattern warrants watching beyond midweek.
