What happened

Portugal’s weather agency IPMA forecasts weekend temperatures above the seasonal average, with rain and thunderstorms, as a tropical air mass brings Saharan dust over the Iberian Peninsula.

Why it matters

Temperatures this weekend could reach 35°C in mainland Portugal, a spell of hot weather that IPMA, Portugal's meteorological institute, considers unusual for the time of year.

Common ground

Thermometers are expected to read between 30°C and 35°C across most of the country, with highs of up to 39°C in some inland areas of the Tagus Valley.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
