Adelaide should begin a three day run of days above 33 degrees today before showers and a couple of storms arrive later in the week.
Today will be a stunning sunny day in Adelaide with a top of 34 degrees. On Wednesday the mercury will rise higher still to 36 degrees with only a few clouds in the sky.
Wednesday night will be the second, and warmest, in a run of four nights that should fail to dip below 20 degrees. Much of the night will be in the high twenties with no cool change to bring relief from what will be a restless night for many.
On Thursday the temperature is likely to rise quickly to 36 degrees. If each day exceeds 33 degree it will be the longest December run above 33 degrees in Adelaide in three years. During Thursday winds will tend southwesterly and cloud will increase with a trough, dropping the temperature slightly.
A warm airmass will linger over the region on Friday helping the temperature reach around 30 degrees while the trough should bring a few showers and the risk of thunderstorms.
On Saturday showers and afternoon storms are a risk, but these should ease during the evening allowing for a mostly dry Sunday. By the end of the week Adelaide is likely to gain 3-8mm, although storms could bring heavier localised falls.
