Dense Fog and Gentle Warmth: Jacksonville’s Thursday Outlook

Morning: Navigating the Fog

Jacksonville residents waking up this Thursday, January 22, 2026, will find a thick blanket of gray greeting them. The National Weather Service in Jacksonville has issued a notice regarding locally dense fog that is expected to persist through the mid-morning hours. Visibility in several neighborhoods, particularly those near the St. Johns River and the coastal inlets, may drop significantly. Local authorities are urging commuters to exercise caution, adjust their speed, and utilize low-beam headlights to navigate the murky conditions safely. Temperatures during the early hours will hover in the mid-50s, providing a damp but relatively mild start to the day compared to the record-breaking freezes experienced earlier this month.

Afternoon: A Return to Mild Florida Winter

As the fog dissipates toward midday, a high-pressure system currently sitting over the region will take control. The afternoon prediction suggests a pleasant shift toward partly sunny skies. While high-level cloudiness may linger, Jacksonville is on track for a significant warming trend. After a week that saw local temperatures plummet to a record-tying 22 degrees, today’s high is forecast to reach a comfortable range between 63°F and 69°F. This spring-like warmth is a welcome relief for residents who have spent the last few days protecting pipes and covering sensitive tropical plants. No significant rainfall is expected during the afternoon hours, with precipitation chances remaining below five percent.

Evening: Coastal Breezes and Celestial Activity

The evening forecast remains stable with overcast conditions likely returning as the sun sets. Temperatures will descend slowly into a low of approximately 55°F overnight. Winds are expected to remain light and variable, primarily coming from the west at 5 to 10 miles per hour. However, the most unique aspect of today’s weather isn't happening on the ground, but in the atmosphere. The Space Weather Prediction Center has noted a G1 Minor geomagnetic storm active today, which could lead to minor fluctuations in power grids or slight interruptions in satellite communications, though it is unlikely to be noticed by the average resident.

Safety Reminders and Summary

• Fog Hazards: Dense fog will be possible again late tonight and into Friday morning. Always leave extra distance between vehicles.
• Temperature Range: Expect a high of 69°F and a low of 55°F.
• Rain Forecast: Minimal to no rain is expected today, with only a 0.01-inch possibility of patchy mist in the early morning.
• Space Weather: A G1 Minor geomagnetic storm is in effect for January 22.

Overall, Thursday serves as a transitional day for Jacksonville, moving away from the arctic chill of mid-January and toward more seasonal, temperate Florida weather. Keep your light jackets handy for the evening, but the heavy winter coats can likely stay in the closet for now.
