Arizona weather forecast: Warmer temperatures this weekend
Evening Weather Forecast - 3/8/26
Temperatures climbed on Sunday, but a new storm system will move in on Monday. FOX 10's Erica Horvatin has more on how this will bring cooler weather before a high pressure system brings another round of warm temperatures.
PHOENIX - The weekend began with a beautiful and breezy start with temperatures warming up yet again into the upper 70s across the Valley. Temperatures continued to warm into Sunday with the return of above-average temperatures in the 80s.
Sunday:
Sunday was a hot day, as temperatures soared back to 89 degrees in the Valley.
The warm-up will be cut short, as we have a low pressure system bringing in some cooler temperatures over the next few days. We will also see the chance for showers and thunderstorms across the Valley and other parts of Arizona.
Tonight will be mostly clear, with a low of 60 degrees in the Valley.
Monday:
Monday will be mostly sunny, with a high temperature of 81 degrees. Clouds will increase during the afternoon and evening, and storm chances will begin during the evening hours.
Storms will be possible in the Valley throughout the evening and overnight, with a chance of heavy downpours, strong wind gusts and small hail. The best chance for these storms will be between 5 p.m. and 2 a.m.
The high country will see showers and storms as well during the evening and overnight, especially in the mountains of eastern Arizona. The Flagstaff area may see a few showers or storms, but far northern and western Arizona will be mainly dry. Snow will be limited to 8,000 ft and above, so only the higher peaks and a couple of spots along the Rim will see the potential for a light dusting of snow overnight.
Looking Ahead:
The heaviest rain will end by Tuesday morning, but there will be isolated showers possible in the mountains of eastern Arizona through Tuesday afternoon. Temperatures will cool down even more on Tuesday, with the Phoenix area seeing a high of around 74 degrees.
The rest of the week will be dry, and temperatures will warm back to the low 80s on Wednesday, before skyrocketing into the 90s on Thursday for the rest of the week. It will be dry, sunny, and warm with clear skies and overnight lows increasing into the 60s.
