Waltham Weather Outlook: June 22–26

After a comfortable stretch of weather this past weekend, with lower humidity, seasonable temperatures, and abundant sunshine, this week remains more uncertain, but there is growing potential for a widespread soaking rain Monday into Monday night if a developing low pressure system tracks close enough to southern New England. Should that occur, beneficial rainfall would be welcome after recent dry conditions. Drier, pleasant summer weather is expected to return by the middle of next week.
