PHOENIX — PHOENIX — The monsoon storm threat continues this weekend and we'll get break from extreme heat in the Valley.

High pressure to our east is allowing abundant monsoon moisture to flow in, with a 40% chance of storms in the Valley today and tomorrow.

Daytime highs will only reach the upper 90s to low 100s, putting us several degrees below normal for this time of year.

Flood Watches have been extended through Sunday morning for all of northern Arizona.

Gusty winds, lightning and heavy downpours are the main threats with any storms that move through, but there's also an increased risk for flash flooding near our wildfire burn scars.

Storm chances in the Valley will decrease a bit next week, but still remain in the forecast.
