While Whyalla residents did not see much rain, they should prepare themselves for possible showers today.

Whyalla has experienced over the week "muggy" and overcast weather conditions with temperatures remaining in the mid 20s.

The weekend will see temperatures rise to high 20s to low 30s with fine and sunny weather to be expected.
