A Brisk Break from the Storms: Jacksonville’s Chilly Presidents' Day Forecast
Post-Storm Chill: Jacksonville’s Clear and Brisk Presidents' Day
After a weekend marked by turbulent weather and severe storm warnings, Jacksonville residents can expect a significant shift in conditions this Monday, February 16, 2026. As the powerful cold front that triggered Sunday’s tornado watches moves out into the Atlantic, a much cooler and drier air mass is settling over the First Coast. For those heading out for the Presidents' Day holiday, the umbrella can likely stay home, but you will definitely want to reach for a sturdy jacket as temperatures take a noticeable dip.
Morning: A Cloudy and Brisk Start
The morning hours will begin with lingering cloud cover as the remains of Sunday's storm system exit the region. Early risers will notice a sharp drop in mercury compared to the humid conditions of the previous day. Temperatures in the early morning will hover in the low 50s, with a stiff breeze making it feel even cooler. Winds will be out of the north-northeast at 10 to 20 mph, occasionally gusting up to 15-20 mph, particularly near the St. Johns River and the Atlantic coast. Expect a gray but dry start to your holiday commutes or morning errands.
Afternoon: Sun Peaks Through the Cooldown
By midday, the thick cloud deck is expected to break, leading to partial clearing and periods of welcome sunshine. Despite the sun's appearance, the persistent northerly wind will keep temperatures capped well below seasonal averages. The high for the afternoon is projected to reach only between 61°F and 64°F—a stark contrast to the mid-70s seen just 24 hours ago. It will be a crisp, bright afternoon, perfect for outdoor activities provided you are dressed for the wind chill. Humidity levels will remain low, providing a refreshing, albeit chilly, atmosphere across the city.
Evening and Overnight: Clear Skies and Cold Temps
As the sun sets, the remaining clouds will vanish, leaving Jacksonville with mostly clear skies for the evening hours. This lack of cloud cover will allow for significant radiational cooling, causing temperatures to drop quickly once the sun goes down. Evening temperatures will slide into the 50s shortly after dusk, eventually bottoming out at an overnight low near 48°F to 51°F. Winds will gradually calm to 5 to 10 mph overnight, but the chill will persist well into Tuesday morning.
Warnings and Marine Conditions
While the threat of severe thunderstorms and tornadoes has passed, a Small Craft Advisory remains in effect for local coastal waters due to the persistent north-northeast winds and elevated surf. Swimmers and boaters should exercise caution, as rip current risks remain elevated following the weekend's storm surge. No further rain is expected for the remainder of the day, with the chance of precipitation sitting at a negligible 15% to 20%.
