The pleasant Monday evening — 77°F in Geneva right now, skies mainly clear, barely a breeze — is genuinely the calm before the storm. A strong cold front is bearing down from the west, and by tomorrow the Finger Lakes will be dealing with a very different day.
Tonight stays quiet and warm, with lows only dropping to the mid-50s in most areas. No frost concerns, no precipitation, no alerts. Enjoy the open windows.
Tuesday is where attention belongs. Southwesterly flow will pull moisture northward through the morning hours, with surface dew points climbing into the mid-to-upper 60s by midday. Scattered showers — likely debris from overnight convection upstream — could move through the region in the morning hours, with the main round of showers and thunderstorms arriving through the afternoon and evening as the front pushes through. NWS Buffalo is flagging the possibility of severe thunderstorms Tuesday. High near 79°.
The front clears the region by Wednesday, leaving behind noticeably cooler and drier air. Highs drop to around 70° with a chance of a lingering shower or two before skies clear Thursday. Friday through Saturday look pleasant, with highs climbing back toward 80° and beyond.
