Thundershowers with heavy rain and cloud to ground lightning are possible, with most lasting 30 minutes or less.
Some clouds will begin to thin out starting mid-afternoon through the early evening hours. This could provide enough time for one or two stronger storms capable of strong winds and large hail to develop for western suburbs.
If you are outside and hear thunder, the safest decision is to move indoors or inside a car to reduce the threat of a lightning strike.
