PHOENIX — Scattered storm chances will stick around across Arizona as we start the week.

A Flood Watch is in effect today for southeastern Arizona. Heavy rain in that part of the state may lead to flash flooding, especially near burn scars and low-lying crossings. Never drive through flooded roadways.

A Flood Watch for southern, eastern and northern Arizona will be in affect all day Tuesday. As more heavy rain and flash flooding is expected.

Storms developing along the Mogollon Rim could send outflows into the Valley tomorrow evening, kicking up gusty winds and blowing dust before any rain arrives. Valley chances are slight for pop-up storms Tuesday evening.

Storm chances then back off for the rest of the work week.

High pressure will intensify late in the week, sending temperatures soaring and limiting our rain chances.

An extreme Heat Watch has been issued for central and western Arizona, this includes the Valley, Thursday through next Monday as temperatures will range between 108 to 115 degrees each day. With overnights jumping into the low 90s each night.

Because of the return of extreme heat we have issued ABC15 Weather Action Days for Thursday-Monday.

With the extreme heat remember to limit your outdoor activities and time outside between 10 am -6 pm, stay hydrated, drink plenty of water and electrolytes, bring pets inside and never leave kids or pet inside hot cars.
