PHOENIX — Monsoon storm chances continue this week across Arizona.

Watch out for gusty winds, blowing dust, lightning and pockets of heavy rain with any of the storms that pop up.

We're now up to a 40 percent chance of scattered showers and thunderstorms across the Phoenix metro area starting Wednesday afternoon. Storm chances will continue overnight into Thursday, too.

After that, conditions are looking drier heading into 4th of July weekend.

Humidity will stay high and temperatures will be hot all week.

Valley highs will top out between 106 and 109 degrees on Wednesday before dropping into the lower 100s by the end of the week.

Morning lows will only cool into the mid to upper 80s each day, so we are not expecting much relief overnight.

Slight chances for a few isolated storms will be back in play by Sunday and Monday here in the Valley as highs hover around 105 degrees.
