May atmosphere and afternoon thunder this weekend

BarcelonaTemperatures continue to rise a little more each day: today 25 °C have already been reached in areas of the northeast due to warm southerly winds. In contrast, and surprisingly, they have remained temporarily lower in the southern interior. Thermometers have yet to peak between Friday and the weekend, with many highs above 25 °C in the pre-coastal and inland areas, and even 30 °C will be reached again in Ponent and the Ebro interior.

A warm atmosphere more typical of late May than April, but some changes in weather are coming. Sun and calm will continue to dominate in most regions, but the entry of a little cold air at altitude will clash with the mass of warm air that is embracing us these days, and this will cause cloudiness to grow more vigorously in mountainous areas. Therefore, afternoon showers and thunderstorms will increase in these areas over the coming days.

Friday: sun and heat

The weather will undergo few changes this Friday and it will be sunny in general, with only small nuances. Some decorative bands of high and thin clouds will continue to circulate, while some morning fogs or low clouds will be repeated in inland plains and on some coastal stretch. The novelty will be that the afternoon cloudiness will grow with a little more enthusiasm in mountainous areas and some isolated shower cannot be ruled out in the Pyrenees and eastern Pre-Pyrenees.

All of this with temperatures that will continue to rise a little more, both day and night. A less cold morning and a warm midday, with many highs from 22 °C to 27 °C, a little higher in Ponent and in the interior of the Ebro, where they could reach 30 °C.

Afternoon thunderstorms on the weekend

Towards the weekend, temperatures will peak, with values clearly above average and very warm conditions. Most highs will range between 24 °C and 28 °C in the pre-coastal areas and inland, but in Poniente and the Ebro valley, they will reach 30 °C, as happened last week, although it seems without the very high values of the last heatwave. The mercury will remain subdued on the coast due to the influence of a still cold sea.

All this with clouds that will grow strongly and bring back afternoon showers and thunderstorms in mountainous areas, especially in the Pyrenees, Pre-Pyrenees, and Els Ports. Even on Sunday, these showers could reach other pre-coastal and inland areas in a weaker form. A typically spring situation. On the other hand, sun and calm will continue to dominate in most regions. There is no normalization of thermometers in sight, nor any situation of rain.
