Miami, FL – Afternoon commutes and outdoor activities in Miami face a daily disruption from pop-up thunderstorms beginning Wednesday and persisting through the Juneteenth holiday and into the weekend. Residents should prepare for a typical South Florida summer pattern, where sunny skies can quickly give way to lightning and downpours.
According to the National Weather Service in Miami, the likelihood of showers and thunderstorms returns Wednesday after 11 a.m. The day will otherwise be mostly sunny with a high near 86 degrees, but southeasterly winds could produce gusts as high as 20 mph, particularly near any storm cells that develop. Drivers along I-95 and other major roadways should exercise caution during the afternoon hours for sudden changes in visibility and slick conditions.
The pattern continues for Juneteenth on Thursday, which holds a 20 percent chance of showers and thunderstorms under mostly sunny skies and a high of 87 degrees. Be prepared for brief interruptions to any holiday plans, especially during the peak heating of the day.
As the week progresses, the potential for wet weather increases. The chance for showers and thunderstorms rises to 40 percent by Friday night and climbs to 50 percent for both Saturday and Sunday. This elevated storm probability could impact beachgoers in Miami Beach and anyone with extended outdoor plans over the weekend. Highs will remain steady in the upper 80s.
The threat of daily pop-up storms is expected to continue into early next week. Warnings for lightning and localized heavy rain can be issued with little notice.
Here is a look at the five-day Miami weather outlook:
- Wednesday: High near 86°F, 30% chance of afternoon thunderstorms.
- Juneteenth: High near 87°F, 20% chance of afternoon thunderstorms.
- Friday: High near 86°F, 30% chance of afternoon thunderstorms.
