South Florida could see more potentially dangerous weather this week as a front moves in from the Gulf carrying rain amounts far above the 30-year norm.
On Wednesday, the Storm Prediction Center puts all of South Florida and north to about Daytona Beach at a marginal risk for severe thunderstorms, including the potential for damaging wind gusts and tornadoes.
The storms may bring as much as 2 inches of rain, and a risk of some minor urban flooding. This amount of rain would be “in the range of the maximum observed in a 30-year climatology,” Miami meteorologists wrote in their morning forecast.

A plume of moist, warm air moving in from the Caribbean and southeastern Gulf of Mexico will spread through much of the state early Wednesday through Wednesday night adding ingredients to destabilize the atmosphere.
This map shows the Weather Prediction Center’s forecast for 7 a.m. Wednesday.
A marginal risk of storms is the lowest alert level on a 5-level scale, but does mean that small hail, winds of 40 to 60 mph and a low risk for tornadoes are possible.
The Storm Prediction Center also notes a short wave trough traveling along the subtropical jet stream toward Florida. A short wave trough is a mass of air spinning counterclockwise in a cyclonic motion. It’s usually indicator of dicey weather ahead as it contracts and then spreads out as it moves along troughs and rides in the upper air pattern.
