Heat Safety

Thunderstorms will focus primarily over high terrain areas north and east of Phoenix and across Southeast AZ. Slightly weaker inhibition & slightly stronger easterly flow than previous days may provide better odds (10% chance) for activity to near or move through Phoenix in the evening, despite an expected trend down in instability. Gusty storm outflow winds will be possible in the Phoenix metro and surrounding areas in the evening

Lower desert highs will increase above 110 degrees into this weekend. Elevated moisture levels will lead to high heat indices, especially across Southeast CA and Southwest AZ. Lower desert locations will experience heat indices up to 112-118° through this weekend. Morning low temperatures will also be hovering around daily record warm lows.

Extreme Heat Warnings remain in effect through Sunday across lower deserts locations as localized major HeatRisk continues. Temperatures gradually heat up into the weekend with many lower desert locations exceeding 110 degrees. The elevated humidity levels will make it feel even hotter.

Dangerously hot temperatures are in the forecast through the weekend. Make sure to take the proper precautions to protect yourself from the heat, it is the deadliest weather-related phenomenon.
