WEST PALM BEACH, Fla. — Most of South Florida will be near 70 degrees on Thursday with plenty of sunshine, while the Treasure Coast will reach the mid-60s. The average high temperature in West Palm Beach for January is 75 degrees, so we are still about 5 degrees cooler than normal. Low humidity during the afternoons this week could increase the risk of enhanced fire behavior across interior and southwest parts of the region. Gusty northwest winds could make it feel even colder, with wind chills in the 20s and gusts up to 40 mph. **Portions of this story were assisted by artificial intelligence tools and reviewed by a WPTV journalists to ensure accuracy, clarity, and adherence to editorial standards.
