The Macy's Thanksgiving Day Parade is set to proceed with sunshine and chilly temperatures in the 40s, but gusty winds could present a challenge for the iconic giant balloons. Forecasters predict winds ranging from 20 to 30 mph, potentially nearing the thresholds that would require the balloons to fly at lower altitudes or, in the event of stronger gusts, be grounded altogether. Parade organizers are closely monitoring weather conditions, keeping in mind previous wind-related incidents.
