After a weekend of stifling heat, the approach of a cold trough will bring a almost general drop in temperatures and will increase instability, favoring an increase in cloudiness. As a result, there may be locally strong thundershowers in the centre, north and north-east of the peninsula and in the Balearic Islands and the entrance of a DANA (isolated depression at high levels), according to the forecast of the State Meteorological Agency (Aemet)
This Monday is expected storms in the north-central and northeastbeing more intense and likely in mountainous areas, where even could be strong and accompanied by hail in the Cantabrian mountain range, the Iberian system and the Pyrenees. Occasionally, these storms, less frequent and intense, could affect other areas in the north, east and centre of the country, without ruling out the possibility of isolated dry stormsin the northern plateau and other areas further south. The AEMET has established an orange warning for strong storms and intense rainfall in the Pyrenees of Huesca and the central area of the province. Isolated dry storms are not ruled out in the northern plateau and other areas further south.
The drop in temperatures will be notable and locally extraordinary in the case of the maximums in the Cantabrian Sea, where this Sunday the extreme risk was activated for values above 40ºC. In any case, Temperatures will be significantly high in the eastern third of the peninsula, the central and southern Atlantic valleys, and the Balearic and Canary Islands. Increases are only expected in areas of western Andalusia, inland southeast, the Balearic Islands and the Canary Islands midlands. Temperatures will exceed 36 degrees in the interior of the southern half and the northeast, areas of the northern plateau and the archipelagos, and even locally 40 degrees in the middle of the Ebro.
Heavy thunderstorms with hail this day
He Tuesdayfor its part, is expected to significant drop in temperatures thanks to the fact that the cold trough will displace the ridge and finish crossing the peninsula, giving rise to an increase in instability in the northeastern third.
Likewise, the approach of a Atlantic front Cloudiness will increase in the north, east and the Balearic Islands, with precipitation moving from west to east, and the possibility of showers and storms in the northern and northeastern thirds, which will be more likely and intense in the mountains, even locally strong and with hail in the Iberian Peninsula and the Pyrenees, without ruling out the coasts of Tarragona. That day there is Orange level warnings for storms in the Pyrenees of Huesca and the Cinco Villas (Zaragoza) and occasionally, less frequently and intensely, they may occur in other areas of the north, east, centre and Mallorca, without ruling out isolated dry storms in the northern plateau and in the mountains of the southeast.
Entry of a DANA
Some scenarios do not rule out that a DANA may form in the Mediterranean on Wednesday, which will cause instability in the Mediterranean area, causing the first episode of significant rainfall, affecting the northeast of the peninsula, Levante and the Balearic Islands.
