For Phoenicians, the heat is nothing new, but staying informed about slight changes in the weather pattern is always essential, especially with summer thunderstorms on the horizon. According to the National Weather Service, today's clear skies are expected to shift with temperatures peaking around 107 degrees. While the morning might start off with a gentle north northeast breeze, residents should expect the wind to swing southwest later, potentially reaching up to 20 mph in gusts.

As the day turns into night, there's a slight, 20 percent chance of showers and thunderstorms to cool off the evening—the transition bringing breezy conditions with winds possibly gusting up to 25 mph. The weather service's latest update suggests a similar pattern for the remainder of the week, with chances of precipitation peeking on Wednesday night at 40 percent before tapering off later in the week. Despite the potential for showers and storms, highs remain firmly in the triple digits.

The pattern of calm winds in the mornings followed by light westerly winds in the afternoons is set to continue throughout the rest of the week. Come Thursday, although there's still a 30 percent chance of thunderstorms mainly after 5 p.m., the skies are expected to be partly sunny with a high just over the century mark.

Looking forward to the weekend, Friday should bring mostly sunny conditions with a high inching back towards 105 degrees. By Saturday, the forecast indicates full sunshine, pushing the mercury to around 107. Evenings will bring slight relief with lows hovering around the mid-80s, though Sunday night may drop to a more temperate 85, sans the earlier thunderstorm risks.
