Orlando, Florida – Sweltering summer heat and another round of afternoon thunderstorms are set to disrupt Orlando and Central Florida by Friday, July 18th. With heat index values climbing as high as 103°F and the risk of pop-up storms targeting key routes like I-4, drivers and outdoor workers should brace for delays and dangerous conditions.
According to the National Weather Service, a 40 percent chance of showers and thunderstorms will develop after 2 p.m. Friday, pushing temperatures near 94°F. South-southeast winds will increase humidity, creating a heat index that could challenge even seasoned Floridians. Officials recommend limiting outdoor activity, hydrating often, and seeking shade during peak hours. If you’re traveling on I-4 through Orlando in the afternoon, expect sudden downpours, reduced visibility, and ponding on roads.
Saturday and Sunday will see continued hot and humid conditions, with highs pushing 96°F each day. Afternoon storms remain possible, especially for outdoor events and theme park visitors. Calm winds will offer little relief, so anyone with weekend plans should monitor radar and plan for quick shelter options.
Looking ahead, the five-day outlook keeps the storm threat alive into next week, with Monday and Wednesday featuring a 60–70% chance of afternoon thunderstorms. Each day brings heat indexes in the triple digits and a persistent risk for heavy rain and lightning, especially during the late afternoon commute.
Stay alert for updates, check for potential advisories, and avoid non-essential travel during peak storm periods. Warnings and watches may be issued as the pattern continues.
