Waltham Weather Outlook: Feb. 11 – Feb. 18, 2026 

The deep Arctic air mass that dominated the region in recent days is finally retreating offshore. While temperatures remain wintry, we transition back toward more seasonable mid-February conditions. The pattern turns relatively quiet through the end of the week with only nuisance snow shower chances. Attention then shifts to late weekend into early next week, where a potential coastal storm bears watching, though track uncertainty remains high at this time.
