PHOENIX -- Headed to a Friday night football game or a camping trip during this holiday weekend?  Keep an umbrella or poncho handy, and watch for building cumulus clouds.

Deep monsoon moisture will linger across all of Arizona Friday and into the weekend. Combined with daytime eating, storms may explode without any notice.

The main threats from any storms that develop will be heavy rain, gusty winds and dangerous lightning. Outflow boundaries from storms could produce blowing dust in the Valley. Storms should track from the east and southeast to the west and northwest.

In Phoenix, expect a 40 percent chance of storms during the afternoon and evening hours with a high of 98 degrees on Friday. Storm chances remain elevated, in the 30 percent range for both Saturday and Sunday with highs around 101 degrees.

Better chances for storms lie in the mountains, where chances will range from 40 to 80 percent.

By next week, we return to a more typical monsoon pattern. As humidity decreases, we will see Valley temperatures heat back up to around 105 by Tuesday.
