Waltham Weather Outlook: April 4 to April 12, 2026

A sharp backdoor front brings a noticeable chill to start the weekend, especially Saturday afternoon. Showers develop Saturday night into Sunday as milder air briefly returns. Early next week trends cooler and mainly dry, though a few rain or snow showers are possible Monday night into Tuesday morning. The second half of the week looks increasingly pleasant with dry weather and a gradual warmup, likely reaching well into the 60s by next weekend.
