San Antonians may need to dust off their umbrellas and prepare for wet roads as the forecast calls for a series of showers and thunderstorms this Juneteenth week. According to the National Weather Service, there's a high chance of precipitation, with some storms potentially producing heavy rainfall. Starting off lightly, there is a 20 percent chance of showers today, with partly sunny skies and a high near 94 Fahrenheit degrees. The heat index, meanwhile, is expected to climb to a sweltering 102 degrees.

As we progress into the evening, those planning outdoor activities might be pleased to find a lesser chance of disturbances. "A 10 percent chance of showers and thunderstorms before 7pm. Mostly cloudy, with a low around 76. East wind 10 to 15 mph, with gusts as high as 25 mph." is what the National Weather Service predicts. But prepare to quickly bring the festivities indoors, as Juneteenth could be ushered in with showers and thunderstorms. The chance of precipitation is forecasted at a significant 80 percent, with new rainfall amounts between 1 and 2 inches possible.

Heavy rains might lead to relaxing indoor activities, as Wednesday night teases with more showers likely and possibly another thunderstorm. The outlook is mostly cloudy with a low around 75 degrees. The chance of precipitation falls to a moderate 60 percent on Thursday, with the likelihood of rain lessening further to 30 percent by Friday. Through the weekend, a lingering 20 percent threat of thunderstorms creeps into a mostly sunny Saturday.

As we approach Sunday, the skies are set, once more, to clear up, giving way to what might be a sunnier disposition for the city approaching the new week. "Mostly sunny, with a high near 94," describes the forecast for early next week.
