Residents in Miami should prepare for a series of potentially stormy afternoons as forecasts predict increased chances of showers and thunderstorms throughout the week. According to the National Weather Service, Monday will see a 30 percent chance of showers and thunderstorms, particularly after 2pm, with heat index values soaring as high as 106 degrees. The evening outlook remains partly cloudy with similar storm chances before 8pm and lows hovering around 80 degrees.

As the humid air lingers over South Florida, Tuesday appears comparable to Monday, with a 30 percent chance of afternoon storms notwithstanding a mostly sunny start. NBC Miami echoes this, reporting a slight uptick in rain chances, sitting around 30-40 percent. With highs flirting with the mid-90s and "feels like" temperatures ranging between 100-105 degrees, heat is set to be a consistent companion during the daylights.

Midweek forecasts from the National Weather Service suggest a heightened probability of precipitation. A 50 percent chance of showers and thunderstorms is expected on Wednesday, with mostly sunny skies early giving way to potential disturbances as the day progresses. Lows on Wednesday night are anticipated to remain around the 80-degree mark.

Continuing through the end of the week, residents should not expect much reprieve from the wet weather. By Friday, storm chances are forecasted to climb to 60 percent, as observed in Thursday's expectations, which also predict likely showers and thunderstorms, mainly after 2pm. Both sources agree that while sunlight may grace the mornings, the afternoons invite an increasingly stormy pattern. Southeast winds will continue to waft through at a gentle pace, somewhat moderating the high temperatures set to peak near the 90-degree threshold.

A look towards the weekend suggests a continuation of this pattern, with NBC Miami predicting rain chances of 70 percent on Saturday. Similarly, the National Weather Service warns of likely showers and thunderstorms, mostly sunny conditions not withstanding, carrying a high near 90 degrees. Both nights over the weekend, storms are likely to continue with lows around 79 degrees, making for muggy evenings following the heated days.
