After three days of scorching temperatures during the First Alert Weather days, Phoenix is finally set to experience some relief as the excessive heat warning comes to an end on Friday night. The recent heatwave has shattered records, with an overnight low of 87 degrees, breaking the previous record of 85 degrees set in 1977.

The average overnight low for this time of year is typically 76 degrees, making the recent temperatures unseasonably high. While many Valley cities reached temperatures exceeding 110 degrees in the late afternoon, they managed to stay under the record high of 115 degrees recorded in 1985.

In some positive news, light showers have been reported in the upper elevations of the White Mountains in eastern Arizona. These showers are due to a flow of moisture pushing up from the south, rotating around a significant ridge of high pressure that has been responsible for the record-breaking heat.

Although the excessive heat warning remains in effect until Friday night, Arizona can expect a slight drop in temperatures and the introduction of more clouds across the desert as the ridge starts to push to the east. This change may also bring a slight chance of thunderstorms, mainly in the higher elevations of eastern Arizona over the weekend.

Flagstaff, located in the High Country, also experienced unusually warm temperatures, recording its earliest 90-degree day on record with 91 degrees on Thursday. However, relief is on the horizon for the region as the ridge moves away, and temperatures are expected to stay below 110 degrees from Sunday through Tuesday.

While temperatures may temporarily decrease over the weekend, the heat will likely make a comeback by mid-week. Residents are advised to remain cautious and take necessary precautions to stay safe during these extreme weather conditions.

In conclusion, Arizona is bracing for a respite from the scorching temperatures that have gripped the region. With the excessive heat warning ending on Friday night, cooler temperatures and a chance of thunderstorms are expected over the weekend, especially in the higher elevations. However, the heatwave is not over yet, as temperatures are predicted to rise again by mid-week. Stay prepared and stay safe during this fluctuating weather pattern.
