Icy Sun: Jacksonville Shivers Under Arctic Blast as Freeze Warning Extends

Morning: A Bitter Start to the Commute

Jacksonville residents woke up to a bone-chilling Tuesday as an arctic air outbreak continues to grip the region. Early morning temperatures plunged into the mid-20s for inland areas and the lower 30s along the coast. While local roads remained dry for the morning commute, the National Weather Service has maintained a Freeze Warning for the area through 9:00 a.m. The primary concern this morning is the dangerous wind chill, which has made 'feels-like' temperatures drop into the teens and even single digits in some neighborhoods due to persistent northwesterly breezes.

Afternoon: Bright Skies with a Sharp Chill

As the morning progresses, the heavy frost is expected to clear, giving way to bright, sunny skies. However, do not let the sunshine deceive you; the cold air mass is firmly entrenched. Afternoon high temperatures are forecast to reach only the upper 40s to near 50 degrees. This is significantly lower than the historical average for late January, making today one of the coldest days of the season. Despite the clear conditions, the breeze will continue to provide a sharp bite to the air, making outdoor activities uncomfortable without heavy winter gear.

Evening and Night: The Big Freeze Returns

The mercury will begin a rapid descent immediately after sunset. For Tuesday evening and into the overnight hours, skies will remain mostly clear, allowing for maximum radiational cooling. Lows are predicted to tumble back into the mid-20s for most of Duval County, with coastal regions staying slightly warmer in the low 30s. Meteorologists warn that another widespread freeze is certain, and frost will likely begin forming early in the evening on lawns and windshields.

Safety Alerts and Vital Precautions

Health officials have issued a high-risk advisory for hypothermia, particularly for vulnerable populations such as the elderly and those without adequate heating. The City of Jacksonville has activated its Warming Center Contingency Plan to assist those in need. The Legends Center on Soutel Drive is operating as a primary warming station, with JTA providing free transportation from various bus stops for those seeking shelter.

• Protect the 4 P’s: Ensure that People, Pets, Plants, and Pipes are protected. Bring pets indoors and cover sensitive vegetation.
• Pipe Safety: Residents are encouraged to wrap exposed outdoor pipes to prevent bursting as temperatures remain below freezing for several hours.
• Space Heaters: If using portable heaters, keep them at least three feet away from flammable materials and never leave them unattended.

With sub-freezing mornings expected to persist through the remainder of the week, today serves as a critical reminder to stay weather-aware and check on neighbors who may be at risk during this extreme cold snap.
