MOST ACCURATE FORECAST: Tracking temperatures below 110 degrees with more chances for monsoon storms

Posted
and last updated

PHOENIX — We are tracking temperatures below 110 degrees all week!

The subtropical high over Texas is still sending monsoon moisture into Arizona for the start of the week.

Storms are likely to fire up across the higher terrain of northern, eastern and southeastern Arizona.

Valley chances heavily depend on outflows from surrounding storms moving into the Valley to generate the pops in our afternoons and early evenings, so it is a wait and see.

Any storms that develop could produce powerful wind gusts, areas of blowing dust, small hail, dangerous and deadly lightning, heavy rain and flooding, especially near wildfire burn scars.

When it comes to the heat, a bit of relief the rest of the week Valley highs will stay just below 110 degrees with overnight temperatures back in the mid to upper 80s.

Phoenix has set a new record for the longest stretch of consecutive days at 100 degrees or hotter with 77 triple-digit days in a row as of August 11, 2024.

The previous record was 76 triple-digit days in a row set in August of 1993.
