Miami starts Veterans Day warm and partly sunny, with plenty of humidity in the air. Sunshine will push the temperature to about 84 degrees before scattered showers and thunderstorms become possible later in the afternoon.

Afternoon Storms Could Interrupt Outdoor Plans

Showers and thunderstorms may develop during the afternoon. Any stronger storm could bring a brief downpour, lightning and gusty winds.

The strongest storms are expected to favor areas around Lake Okeechobee and Palm Beach County, but scattered activity may reach the Miami metro area.

Afternoon storms are expected to form as sea-breeze boundaries move inland and interact. The National Weather Service Miami forecast discussion says the strongest cells are most likely near Lake Okeechobee and Palm Beach County, where storms could bring frequent lightning, gusty winds and small hail.

Thursday Stays Warm Before A Front Arrives

Thursday will be mostly cloudy with a high in the lower 80s and another 30% chance of afternoon showers and thunderstorms. The main cold front is expected to approach Thursday night and cross South Florida Friday morning, bringing a noticeable shift in the air.

Friday’s high should reach about 79 degrees, followed by a low near 63 degrees Friday night. Northwest winds will strengthen behind the front, setting up a cooler and drier start to the weekend.

The front’s main impact will be a sharp change in the air mass: the NWS Miami forecast discussion describes the weekend air as the coolest of the fall so far. Friday night lows could fall into the lower 50s near Lake Okeechobee and interior Southwest Florida, while most other areas are forecast in the mid to upper 50s and the immediate east coast may stay in the lower 60s.

Breezy, Cooler Weekend Weather

Saturday looks mostly sunny, with highs in the lower 70s across most areas, while breezy conditions are expected. Sunday will be dry and milder, with temperatures climbing back toward 79 degrees.

Rain chances increase again early next week, with showers and thunderstorms possible Monday and Tuesday as moisture returns.
