The days of intense heat have passed and a more or less long period is coming in which the meteorological predominance will be instability. After the rains yesterday afternoon in central areas due to intense heat, a DANA (Isolated Depression at High Levels) by the Gulf of Cádiz that will spoil the plans of many for this weekendin which many public and private pools open in Spain.
Thus, in addition to the rains, there will be a significant drop in temperatures to levels more typical of spring. The first areas to notice this decrease are those located in the southwest quadrant of the peninsula. These declines will be notable and even locally extraordinaryand during tomorrow the same thing will happen in a large part of the Peninsula with the exception of the Ebro valley and the Mediterranean area, where thermometers will continue above 30 degrees, with maximum temperatures that may exceed 35.
Heavy rain and hail
As for rainfall, heavy rain is expected this afternoon in the northwest of the peninsula, without ruling out that it will also occur in other parts of the western third. In some areas, storms They will be especially intense and will be accompanied by hail.
The weekend will be wet as DANA will cause widespread rain throughout the day tomorrow, although the areas in which It will be less likely that it will rain if they are located in the extreme northeast and southwest of the peninsula., while in large areas of the northern half and around the Iberian system rainfall will be quite intense. These rains will be muddy in many areas, due to the haze, so if you plan to wash your car it will be better to wait until next weekend.
For Sunday's day, DANA will have already swept the peninsula from south to north and will be installed in the northeast, where the heaviest showers of the day are expected to occur. It is also likely that it will rain, although with less intensity, in the rest of the northern half, without ruling out that storms reach the Balearic Islands.
From the DANA to the Atlantic trough
During next week there will continue to be atmospheric instability. And after the passage of the DANA, the peninsula will come under the influence of an Atlantic trough. But what does this really mean? The term defines an unstable zone where the air, much more humid and warmer than in the neighboring anticyclonic zones, is forced to rise, generating clouds of great vertical development that usually cause intense and persistent rains. The barometric depressions associated with the troughs would be equivalent to a kind of warm but stationary frontfrom which the persistence of precipitation is derived.
Therefore, atmospheric instability will last throughout the week and will generally affect the entire Peninsula. It will be time to take out the umbrella and for the reservoirs to recover after these days of intense heat in much of the country.
The Areas that could be “saved” from the rains are those located in the extreme south of the peninsulaalthough the AEMET indicates that today it is difficult to pinpoint precisely the areas where the showers will be more intense.
Some scenarios point to atmospheric stabilization starting on Wednesday or Thursday, but there are others that postpone it until the weekend, so It is still too early to define when temperatures will rise again.
What is true is that the meteorological models seem determined to keep the pools empty throughout the month because The forecast for the remainder of the month is not at all hopeful.
This is what it indicates Meteored, which indicates that the most relevant thing for the monthly forecast is the absence of ridges and blocking anticyclones to the southwest of Europe, however, there are regions of high pressure in high latitudes that allow the descent of cold air masses and depressions to our latitudes. The polar jet will remain weak and unstable, facilitating the movement of air masses away from their latitude of origin.
Therefore, they indicate that “It does not seem that June is going to end with great temperature extremes, as has already happened with May. But the likelihood of it ending as a significantly warm month is undoubtedly high. “Currently the Atlantic Ocean has an exceptional positive thermal anomaly, and all air masses of maritime origin will be conditioned by these extraordinarily warm waters.”
