Weather in Madrid / Sevilla / Cadiz right now?

We have some 38 hours to leave for Madrid and then continue downsouth to Andalusia. I searched the on-line weather forecasts, BBC being my favourite one and wonder if the forecast is somehow correct - it says the temperatures should be around 19/20°C in Madrid, 22/26°C in Sevilla, all nice and sunny. Still, should I expect the weather to be rather changeable at this time of the year?

Looking forward to all the SUN heeeeheeee!!!

It's sunny, 19º C, and there's a nice breeze blowing right now. It's cooler than last week, and temperatures are expected to dip over the next few days. A good rule of thumb is that when it's a holiday period in Spain, as it is this week, the weather takes a spiteful turn for the worse
