Weekend air in Watertown sits near 79°F / 62°F, plus only light rain on the books (~0.17 in) — enough to decide whether the trip is on.

Use the outlook as the itinerary filter: plan the outdoor pieces when 79°F feels right, and keep a café backup if clouds show up.

If the numbers still look good by Friday, lock the plan around 79°F — not a vague “nice weather somewhere.”
