Waltham Weather Outlook: Oct. 8 – 15

After several warm, almost summery days, a strong cold front will usher in a major pattern change midweek. Waltham transitions from highs near 80°F to brisk fall air by Thursday and Friday. Frost is possible in some outlying areas by early Friday morning. The weekend looks dry and seasonable, though a potential coastal storm may bring showers and gusty winds late Sunday into early next week. Confidence remains low for that system, but it’s worth watching.
