Father’s Day is opening on a genuinely agreeable note — partly cloudy skies and mid-50s temperatures regionwide, which makes for a comfortable Sunday morning if you’re heading out early. That said, this day has two distinct chapters, and the second one arrives after dark.
Through the morning and into the afternoon, conditions stay dry and seasonably warm. Highs reach the mid-to-upper 70s across most of the region — near 75°F in Geneva and Auburn, climbing to around 78°F in Ithaca and Elmira. A light westerly breeze keeps things comfortable. Father’s Day cookouts and outdoor plans look fine through early evening, with sunset arriving at 8:50 PM on this longest day of the year.
The change comes late tonight. A surface low developing over the Ohio Valley will track east, pushing a warm frontal boundary into western New York and drawing moisture northward. The National Weather Service in Buffalo notes that guidance is still working out the precise timing, but the general picture is showers moving in after midnight and becoming more widespread through Monday. Rainfall Monday could be heavier at times as the low’s energy moves through. Rain tapers from northwest to southeast Monday evening into overnight.
Tuesday brings some lingering drizzle with highs near 74°F, then a dry stretch arrives Wednesday and Thursday — mainly clear skies and highs in the mid-70s. Friday’s IMSA weekend opening day at Watkins Glen carries a 39% precipitation chance, with similar odds Saturday for the support races. Race fans planning the trip to The Glen should keep an umbrella handy, though neither day looks like a washout.
