.SHORT TERM (TDY-FRI)... Issued at 410 AM EDT Thu Sep 11 2025
A few showers and storms are currently present over the southern waters this morning. This activity could bring lower clouds and some rain to coastal areas across SW FL. Meanwhile, a frontal boundary associated with area of low pressure over the Gulf remains stalled south of the Tampa Bay area. There should be plenty of moisture to support showers and storms along and south of there, as drier air filters down over the Nature Coast. Cloud coverage should increase through the day with afternoon temperatures struggling to reach 90 degrees. Northeasterly winds prevail during this time.
On Friday, similar conditions are anticipated with stalled boundary moving slightly south and chances of showers shifting along with it. An upper level trough will push weak low out of the area and allow drier air to push further south.
