The brutal summer heat continues to impose itself upon Phoenix, Arizona, with the National Weather Service predicting a high of 112 degrees today. The mercury is set to soar under clear skies, with minimal relief from the light breezes that are expected to shift from east-northeast to west-southwest as the day progresses.

Those seeking respite from the heat during nighttime may find a little comfort, as lows are forecasted to hover around 89 degrees. The static hum of air conditioners will likely be the soundtrack of the night, as the west wind blows at a modest 5 to 10 mph. According to the National Weather Service, the persistence of heat continues into Sunday with sunny skies and a high of nearly 108 degrees. The anticipated heat index—what the temperature feels like to the human body when relative humidity is combined with the air temperature—could climb as high as 111.

Currently, Phoenix residents are eyeing an upcoming slight chance of relief. Sunday night carries a 30 percent chance of showers and thunderstorms, mainly post-11 pm. The forecast, partly cloudy with an persistent low around 89 degrees, may bring a disruption to the relentless heat if the thunderstorms decide to make an appearance.

Looking ahead, Monday's weather is slated to remain mostly sunny with a high hovering near 107 degrees and continuing light west-southwest wind. Nightfall offers a 20 percent chance of precipitation ahead of 11 pm. The remainder of the week doesn't stray far from the pattern, with daytime highs expected to consistently reach over 100 degrees and minimal chances for rain aside from Thursday night, when there's again a slight 20 percent chance for showers and thunderstorms.
