Miami residents can expect a mix of clear skies and increasing chances for showers and thunderstorms as the week progresses. Tuesday could bring stray showers in the afternoon with high temperatures creeping close to the 90-degree mark. Rainfall amounts could be less than a tenth of an inch, unless thunderstorms decide to quickly and dramatically change the tune, according to the National Weather Service.

The localized weather conditions seem to fully embrace the balky heat—heat index values have the potential to hit 100 degrees today. The forecast anticipates that the calm will become disturbed by an eastward whisper of a wind, brushing at roughly 5 mph. This seemingly insignificant breeze could easily be the precursor to the wetter days that lay in wait, as detailed by NBC Miami.

As Wednesday unfolds, the chance of precipitation ramps up to 70%, with an active storm day on the horizon. Morning storms are expected to develop before noon, with conditions raising the risk of street flooding.

The remainder of the week promises to not only sustain but also aggravate the soggy situation. Both Thursday and Friday have high storm potential, with an 80% chance of precipitation. Each storm comes carrying its own threat—intense downpours capable of disrespecting the carefully laid boundaries of the city's streets and drains. “Any thunderstorm could feature intense downpours that would lead to more flooding across the area each day,” an NBC Miami report cautions.

Residents and visitors should brace for a damp and unsettled spell, with highs persistently lounging in the mid-80s while low temperatures at night hover beneficently in the upper 70s. The weekend continues the wet trend, with a 60% chance of showers and thunderstorms.
