Miami residents and visitors should be ready for more rain and thunder as the current weather pattern persists over South Florida. According to the National Weather Service, today's forecast includes likely showers and thunderstorms, particularly after 4 pm, with increasing clouds and a high near 90 degrees. The humidity stands tall at 97%, making the heat index values climb as high as 103 degrees, signaling a notably muggy day ahead.

With showers and thunderstorms forecasted prior to midnight, then a chance of more rain and thunderstorms after 2 am, tonight's weather isn't looking to bring much reprieve. Mostly cloudy skies with a low around 77 degrees await those venturing out after dark. The light and variable winds will offer little comfort from the heat, which the heat index suggests might feel like 81 degrees even into the night.

Looking ahead to Friday, the NBC Miami weather team prompts us to prepare for more widespread afternoon storms, maintaining a rain probability of 70%. The high for Friday is expected to hover around 89 degrees. The weekend forecast suggests a weak front that may usher in some slightly drier and cooler air, though storms are still likely on Saturday with a high of 88 degrees.

Sunday brings a scattered selection of storms coupled with a dip in humidity, presenting a modest break from the relentless mugginess of the week. With a 40 percent chance of rain, the day might offer South Floridians some much sought-after respite. Temperatures will still push the barometers with a high anticipated at 89 degrees, with east winds around 7 mph adding a slighter, albeit inconsistent, breeze to the locale.
