Jacksonville, FL – Dangerous heat will grip Jacksonville on Friday, with the heat index expected to reach near 110°F before storms develop late in the day. Residents should prepare for oppressive humidity and take steps to limit outdoor activity during peak afternoon hours.
According to the National Weather Service in Jacksonville, a slight chance of showers in the morning will give way to thunderstorms after 11 a.m., with storm coverage increasing into the evening. Winds from the southwest at 6 mph could become variable, adding to unstable conditions. Localized flooding is possible where heavier downpours occur, and lightning could disrupt outdoor events and evening commutes.
The heat advisory currently in effect runs through Thursday evening, but Friday’s combination of extreme heat and building storm energy will mark one of the most dangerous days of the week. Those attending outdoor events, sports practices, or after-school activities should have water, shade, and a plan to move indoors quickly if storms approach.
The storm threat eases slightly overnight Friday, but more unsettled weather is likely through the weekend. Updates will be issued if additional warnings are posted.
