Heat ends, but storms arrive

The heat is being the undisputed protagonist of this week at the weather. However The warm episode He has his days (or his hours) counted in much of the Peninsula: as of today the extreme heat will live with rains and storms: some communities will have to alert for very different phenomena.

Variopintos phenomena. Meteorologists foresee that the warm episode that affects the peninsula will fade in the next few days and that at the beginning of next week the instability will be the dominant tonic. The transition will not be simple: during the next few days some areas will see the arrival of rainfall and storms while others

Taguada vs. dorsal. Let’s put some context to understand what is happening at the atmospheric level. A few days ago we saw an arrival of an Atlantic anticyclone and an associated dorsal. The dorsal are areas of high pressures that extend from a high pressures center lengthening the scope of anticyclonic time.

The stability associated with high pressures, along with other factorscontributed to a high insolation that warmed the air of the peninsula until it brought us to the current situation.

However meteorologists They announce now that a trough display in the next few days the dorsal. That is, from a situation we move on to the opposite, with a region of low pressures associated with a storm changing the meteorological panorama.

A heat pause. And how this translates: then that instability will take possession of peninsular meteorology. Some areas will begin to see storms today, but it will be from Sunday, with the arrival of the dorsal, which these are generalized.

Heat warnings and storm warnings. The peculiar transition between two weeks marked by opposite phenomena will leave A singular notice map of the State Meteorology Agency (Aemet), a map in which yellow and orange warnings coexist due to maximum and storm temperatures (and also yellow notices for rains).

In this sense, today it will be the most unique: 14 autonomous communities (all peninsular except Murcia) will see active notices throughout the day. Of these highlight orange notices due to temperatures of up to 40º Celsius in the Sevillian countryside; and orange warnings for storms inside the Cantabrian cornice, from the Asturian southwestern to the inner Bizkaia.

In unknown terrain. Spring is a transit station where changes in the atmospheric situation are not entirely strange. However, we can talk about an anomalous season in terms of meteorology: from a drought we spend some of the months with more rainfall than we have record.

Now we return to one more panorama in the tonic of recent years: with a summer that is advanced leaving us extreme heat during the last week of May. To know what will happen during the real summer we will still have to wait a few weeks.
