After several days of near-summer temperatures across large parts of the country, Spain could now be facing a notable change in weather — and in a very short space of time. Forecast models point to increasing atmospheric instability that may develop into widespread thunderstorms over the coming weekend.

The situation is being closely monitored. Following the arrival of very warm air from the Atlantic and several early storm episodes in recent days, meteorologists are now watching the potential formation of an upper-level low — known in Spain as a DANA. While its exact evolution remains uncertain, current indications suggest conditions could become significantly more unsettled between Friday and Saturday.
If this scenario materialises, large areas of inland Spain would see a clear shift away from early summer warmth towards a more unstable spring pattern, with heavy showers and thunderstorms, frequent lightning, strong wind gusts and even the risk of hail in some areas.
Regions currently most likely to be affected include Castilla-La Mancha, the Madrid region, Castilla y León, the Iberian System, the Pyrenees, the Cantabrian Range and parts of Andalusia. Instability may also develop in Extremadura and inland areas of Galicia, particularly in the early stages of the change.
Friday is expected to mark the beginning of this transition, with Saturday shaping up as the peak day for storm activity across much of the country. However, confidence in the forecast decreases beyond that point.
This is where uncertainty comes into play. Some models confine the most intense activity to northern Spain, while others suggest a further southward movement, potentially extending storm conditions to additional regions. In other words, the risk of storms is high — but their exact distribution is not yet fully defined.
What does appear more certain is that the combination of accumulated heat, increasing moisture and converging airflows will favour the development of large convective clouds. In spring, this typically leads to locally intense and sometimes severe thunderstorms.
Spain therefore heads into the weekend under close meteorological watch, with the potential for a significant shift from stable conditions to a more volatile and storm-prone pattern affecting several parts of the country.
