MOST ACCURATE FORECAST: Excessive heat and chances for monsoon storms

Posted
and last updated

PHOENIX — Monsoon 2024 has been back in action across parts of the Valley tonight!

Rain, lightning and gusty winds have been impacting the East Valley and there's still a chance of more monsoon action in the days ahead.

Our dangerous, record-setting heat wave continues, too.

An Excessive Heat Warning remains in effect for the Phoenix metro area and all of western and southwestern Arizona through Friday night.

So, Friday will be another ABC15 Weather Action Day as a reminder to take action to keep you and your family safe during this dangerous heat wave.

Limit your time outside during the afternoon, stay hydrated with water and electrolyte drinks, and never leave kids or pets alone in your vehicle.

Valley highs will top out around 115 degrees or hotter each day through the end of the week and overnight lows will only drop into the upper 80s to low 90s.

The warm mornings combined with the sizzling hot afternoons will increase the risk for heat illnesses, so make sure that you're staying hydrated and limiting your time outdoors during the hottest hours of the day. Keep an eye on kids and the elderly as they are more susceptible to heat-related impacts..

Monsoon moisture will increase across our state in the coming days, increasing our chances for showers and thunderstorms.

Storms will mainly impact the higher terrain and parts of southeastern and south-central Arizona, but there is a slight chance that storms could make it down into the Valley again on Friday night.

Any storms that develop could bring gusty winds, blowing dust, dangerous lightning, small hail, downpours and flooding, especially along burn scars. So, stay weather-aware and remember to never attempt to drive through flooded washes or roadways.

Storm chances will increase over the weekend. Our best bets for rain in the Valley will be Sunday and Monday.
