A cold front related to the blizzard pummeling the Northeast is chilling Palm Beach County, and as it gets even colder, the county will open cold-weather shelters. The coldest weather that the county will feel this week will last into the morning of Tuesday, Feb. 24, with the worst of it near sunrise, according to the National Weather Service in Miami. Temperatures could drop into the mid-30s and the low 40s across the county, said Ana Torres-Vazquez, an NWS meteorologist.
