PHOENIX — A surge of monsoon moisture is bringing storm chances back to Arizona this week.
Most of the storms will impact the high country and eastern Arizona, but there is a chance a few storms could impact parts of the Valley on Thursday.
Watch out for gusty winds, cloud-to-ground lightning and brief downpours with any of the storms that move through.
Phoenix will top out in the upper 90s on Thursday, putting us right near normal for this time of year.
As our Valley forecast dries out, the triple digits will be back Friday and Saturday.
Then, low pressure will move in from the west bringing cool air and chances for storms early next week.
Increased moisture from Hurricane Polo could increase the risk of heavy downpours on Monday and Tuesday. Stay tuned for updates as we get closer.
