As San Antonio residents brace for another week of sweltering heat, the National Weather Service has issued a forecast that nods to the possibility of respite in the form of scattered showers and thunderstorms. According to the extended outlook by the National Weather Service, a 20 percent chance of precipitation is expected to break through the mostly cloudy skies later today, with temperatures soaring near a high of 93 degrees. The heat index, taunting the triple digits, could escalate as high as 105.

Tonight, the clouds will gather again, suggesting a night where the air, thick with the day's leftover warmth, won't offer much in the way of cooling, as temperatures hover around 77 degrees. Looking forward to tomorrow, the forecast teases a slightly higher 30 percent chance of showers and thunderstorms, mostly after 1 p.m. The reprieve from the heat will be modest, with the mercury predicted to climb close to 94 degrees.

The pattern of sultry days and lukewarm nights seems set to continue into the week, with mostly sunny skies on Monday and highs once again nearing 94 degrees. Come nighttime, the city can expect mostly clear skies, offering little more than a silhouette of hope for cooler air, as temperatures are slated to dip to around 75 degrees.

Winds throughout the week promise only the barest caress, with south southeast gusts potentially reaching 20 mph on Tuesday night. By Wednesday, however, they may prove a force to be reckoned with, with gusts expected to pitch as high as 25 mph under the watch of a mostly sunny sky and a high inching towards 95 degrees.

San Antonio's Juneteenth celebrations this year could be graced by a 20 percent chance of showers and thunderstorms, according to the forecast. Temperatures are slated to be slightly more forgiving on this historic day, with highs around 91 degrees under a mostly sunny backdrop. As the week draws on, thunderstorms may become a more common feature, with a 30 percent chance rolling in by Friday and highs dipping into the more temperate 88 degrees.
