Starting Monday night, South Florida — including Miami and Fort Lauderdale — will begin to feel the impact of much colder air following the historic winter storm that affected large portions of the central and eastern United States.
The same atmospheric pattern that fueled that storm has allowed Arctic air to push farther south than usual. Widespread snow and ice to the north help reinforce a dense, cold air mass near the ground, making it easier for that chill to spill into Florida.
Over the next several days, a series of deep troughs dipping south along the East Coast will dominate the weather pattern. These dips in the jet stream act as a pathway, repeatedly funneling polar air into the Southeast.
