Weekly weather forecast Friday, June 6, to Friday, June 13

Waltham continues to ride the rollercoaster of early summer, with a stormier pattern returning to close out the week.

A moisture-rich atmosphere brings the potential for downpours and thunderstorms Friday into Saturday.

Sunday trends drier, though clouds and a stray shower may linger.

Monday offers a much-needed break with sunshine and low humidity.

Another front midweek brings renewed shower chances, but temperatures stay near to slightly above normal throughout the period, with highs generally in the upper 70s to low 80s.
