A Frigid Start to MLK Day: Jacksonville Faces Freeze Warnings and Wind Chills in the 20s

Arctic Blast Grips the First Coast

Jacksonville residents are waking up to a biting chill this Monday, January 19, 2026, as an Arctic cold front has firmly established itself over Northeast Florida. As the city observes Martin Luther King Jr. Day, the local weather team has designated today a First Alert Weather Day due to dangerously low temperatures that haven't been seen in the region for years. The combination of sub-freezing air and a persistent northwesterly breeze has prompted local officials to issue several urgent weather notices for the morning hours.

Morning Frost and Freeze Warnings

A Freeze Warning is currently in effect for the entire Jacksonville viewing area, extending all the way to the beaches, until 9:00 a.m. early this morning. Temperatures in the pre-dawn hours plummeted into the upper 20s and lower 30s, with inland areas seeing lows as cold as 27°F. Residents can expect widespread frost across the city, making for a sparkling but treacherous start to the holiday. Additionally, a Cold Weather Advisory remains active as northwesterly winds around 6 to 8 mph have driven wind chill values down into the 20 to 25-degree range. Those heading out for early morning memorial services or parades are urged to dress in multiple layers, including hats and gloves, to prevent hypothermia.

Afternoon Thaw and Clear Skies

The good news for those with outdoor plans is that the sun will remain a constant companion throughout the day. Under clear, sunny skies, temperatures will begin a slow climb out of the basement. By midday, the frost will have fully dissipated, and afternoon highs are expected to reach approximately 56°F. While significantly warmer than the morning start, these temperatures remain well below the seasonal average for January. No rain is forecast for today, providing a dry but crisp backdrop for holiday festivities. Winds will remain light from the north, keeping the afternoon air feeling brisk despite the bright sunshine.

Evening Outlook and Community Safety

As the sun sets this evening, the mercury will drop rapidly once again. Monday night will be mostly clear and cold, with patchy frost expected to develop after midnight as temperatures settle into a low of 31°F to 36°F. In response to this extended period of extreme cold, the City of Jacksonville has opened a warming center at the Legends Center on Soutel Drive. The Jacksonville Transit Authority is offering transportation to vulnerable individuals seeking shelter. Local authorities remind residents to remember the 'Four Ps' of cold weather safety:

• People: Check on the elderly and ensure they have adequate heating.
• Pets: Bring outdoor animals inside or provide warm, insulated shelter.
• Plants: Cover sensitive tropical vegetation to prevent frost damage.
• Pipes: Wrap exposed outdoor pipes to prevent freezing and potential bursts.
