Miami, Florida – Sizzling summer heat will be matched by a fresh round of thunderstorms for Miami on Sunday, July 20th, as Florida’s summer weather alert continues. Residents heading out or traveling along I-95 should brace for rapidly changing road conditions, especially after midday. Brief but heavy downpours could spark sudden street flooding and slow traffic on major routes.
According to the National Weather Service in Miami, Sunday will bring mostly sunny skies to start, but a 30 percent chance of scattered showers and thunderstorms is expected after 2 p.m. East winds of 5 to 8 mph may turn southeast later in the day, pushing humid air across the city. While Sunday night looks calm, the pattern quickly shifts as the new workweek begins.
On Monday, isolated thunderstorms return, with rain chances rising again by Tuesday and Wednesday—up to a 50 percent probability by midweek. Temperatures remain steamy, hovering near 89°F most afternoons, while overnight lows stay in the low 80s. Residents should keep devices charged and avoid flooded intersections if storms develop, as localized power outages are possible.
Travelers should use caution on I-95 and other main arteries during heavy rain. For those working outdoors or without air conditioning, limit strenuous activity and stay hydrated. These stormy patterns are typical for South Florida’s summer but still require vigilance.
Showers and thunderstorms will stick around through Friday, July 25th, so check local alerts for any last-minute warnings. Next updates from NWS are due early Monday morning.
