Cool start — fast day potential, chance of rain

A cool 49°F at the start line is ideal for fast times — expect to warm up quickly once you're moving. Light winds shouldn't be a major factor for pacing. There's a chance of rain, so have a backup gear plan ready. Moderate humidity at 74% is worth noting for effort level, especially in later miles.
