High pressure parked over the Desert Southwest is pushing Phoenix temperatures to 113 degrees this week, FOX 10 meteorologist Krystal Ortiz reported Tuesday. Slight midweek storm chances offer a potential break, though heat is forecast to persist through the end of the work week.
The National Weather Service Phoenix office confirmed the pattern Tuesday morning, noting that strong high pressure over the region will lead to abnormally hot temperatures. Outflow boundaries from distant storms may reach the lower deserts, bringing gusty winds and areas of blowing dust as a secondary hazard.
AZCentral reported that the high pressure system is also bringing drier air, keeping temperatures around 110 degrees for the entire work week before storm chances increase. Weather Underground's severe weather tracker shows an Extreme Heat Watch was in effect from Monday morning through Friday evening, with afternoon temperatures flagged as dangerously hot.
Residents should monitor the NWS Phoenix forecast page for updated storm timing and any changes to the heat advisory status.
