Extreme heat in parts of Spain and Portugal, May 3rd
The Spanish heatwave has verified across the Iberian peninsula this weekend, as a large omega blocking pattern has established and is resulting in a significant warm advection into southwestern Europe. Many weather stations reported mid 30s peak afternoon temperatures yesterday, Sunday, May 3rd. It was 33-35 °C in parts of Portugal and up to +36 °C in Cordoba and Sevilla regions, southern Spain! Another very hot day is today and possibly also tomorrow!
This past weekend, a classic omega blocking ridge pattern developed over western and southern Europe. A deep and large upper low is located over the Azores, while high-pressure system strengthening over the Iberian peninsula, France, and further north UK/Ireland. This has then resulted in very warm and stable weather across the western half of Europe.
Here are the peak temperatures across Spain and Portugal yesterday, May 3rd:

With the changes in the pattern in the coming days, it could also deliver higher threat for severe storms into parts of western and central Europe later this week – we will keep you updated soon!
