It’s a busy Friday afternoon at Parc Boutique in northeast Minneapolis. Racks full of women’s fashions greet the customers. But Parc’s owner, Thao Nguyen, says the recent cold snap has hurt her in-store sales. “It’s harder for people to come into the shop,” Nguyen said. Just like how tornadoes and hurricanes disrupt economic activity, there is also a steep cost to our cold weather. The lower the temperature drops, the fewer of us venture outside to shop, dine and recreate.
