Starting next week, the most suffocating days of heat will begin to come to an end in Catalonia. But it will not be a sharp drop in thermometers that will be a real respite for those who long to enter an autumnal climate.
Neither will it happen overnight, nor will it be the storm that has emerged from the remains of ‘Danielle‘ the main reason, although it is one of them, that I get it.
What the vestiges of this former hurricane that has left so many headlines in the last two weeks will entail, is a rain frontprobably associated with a DANA -although with the erratic of its progression it is difficult to determine-.
As of Tuesday, instability
It will be from Tuesday that the rainy front will sweep Catalonia with rainfall that will occur unevenlybut that, in principle and according to the current models -which will have to be confirmed or modified as the days go by-, will maintain a unstable situation throughout the week.
This chain of rainfall days will affect during the first half of the week the Easternmost sector and the coast of Tarragona. Thus, the rains will be more likely both in frequency and quantity in the interior of Catalonia, with special incidence in the Pyrenees Y western foothillsand less on the central coast and Costa Brava, where the trend will be that of a noticeable increase in cloudiness.
Already since Wednesday, the appearance of the showers would remain in the Pyrenees sector but would also focus on the Barcelona and Tarragona coastlines with precipitation nuclei located in the sea that would reach the coast. They will be days in which the combination of hours of sunshine, a rapid increase in cloudiness and the discharge of rain will be constant.
The downside of these much-needed rains in a time of severe droughtwith the reservoirs of the internal basins with only 38% of their capacity, is that these will not always present a continuous, stable and manageable flow, but rather unevenly and, occasionally, as a storms They are probably accompanied by electrical appliance and, perhaps, hail.
The rains will help, but they will not be able to alleviate the consequences of a few months of hydric stress that will lengthen this famine during the next quarter.
On the other hand, the thrust of the southeast component winds will also entail the drag of the suspended dust that causes haze It will not be strange to witness that ‘mud rain‘ which pollutes the environment. They will not be days to hang clothes outdoors, or to wash the car if it has to be left parked on public roads.

Falling thermometers, but without a definitive goodbye to the heat
A is expected drop in temperaturesbut that will be between tuesday and wednesday because for him Monday the thermometers will still continue to rise and the sensation of heat and embarrassment will continue to be present.
On this drop in thermometers, just when the storm makes an appearance, it will simply mean that the maximum temperature is in line with or slightly above the average that would touch for a month of September.

On the other hand, at least throughout the eastern strip closest to the Mediterranean, the lows will remain high for what is usual these days. It will be difficult to experience torrid nights again -temperatures above 25ºC-, but it will still end up exceeding the threshold of 20ºC at night, which is what is considered as tropic night.
Inside, on the other hand, the thermometers will notice a more pronounced decrease. The continuation of the rains for several days will first mean a drop in temperatures and then they will remain stable.
