Stability will regain ground with a rising mercury

The cold front that crossed us this Sunday did so accompanied by a thermal drop that has been noticed everywhere and that, in some cases, has sent the mercury plummeting. This is the case of Lleida, where the 9.5 ºC on Sunday midday contrasts with the 25 ºC on Saturday at the same time. Or Vielha, where the 23 ºC on Saturday are far from the less than 5 ºC on Sunday midday (you will find more data on the thermal drop at the end of this information). In a few hours we have gone from this feeling of advanced spring to one more typical of late winter, especially in high mountains, where it will continue to snow during the next few hours. In addition, showers will affect more regions as the hours pass and will affect the eastern half of the country during Sunday night and Monday morning.

Monday: remnants of instability

The weather will still not be clear during the early hours of Monday: showers will fall in the eastern half of the country and there will be considerable cloudiness everywhere, after a dawn with rain in the center and east of the territory. As the hours pass, however, the sun will gain ground in the south and west and the temperature will tend to rise, at midday after a slightly colder dawn than Sunday's. In the western Pyrenees there will still be snowfall, with a snowline that will rise to 1,100 or 1,300 meters in this sector of the mountain range and a tramontana wind that will intensify again at both ends of the territory. The formation of some scattered and minor showers in the northeast in the mid-afternoon is also not ruled out.

Tuesday: the sun prevails

The meteorological situation will be even more stable from Tuesday onwards, with a sky that will already be completely sunny everywhere and will allow the temperature to rise more eagerly during the central hours of the day. The maximums will once again approach the 25 ºC mark in Ponent and will exceed 20 ºC in many parts of the pre-littoral and the Ebro valley, with a mild atmosphere at midday. The tramontana will remain in Empordà, which will continue to alter the maritime situation in this sector of the Catalan coast and in a large part of the Balearic Sea.

The temperature will maintain its rise and will reach quite warm values by mid-week, with maximums exceeding 20 ºC in a generalized way and a sun that will persist in its dominance.

Balance of an unusual cool-down

It is not uncommon for the temperature to drop or rise several degrees in a few hours, but the thermal change experienced between Saturday noon and Sunday is unusual, with a drop in the mercury that in some cases has been greater than 13 or 14 ºC. Locally, however, the maximum temperature has dropped by more than 17 ºC, as we can see in this graph.
