The anticyclone will last for days: today it will be even hotter at midday
Sunshine and calm will prevail, and perhaps some changes will begin to arrive from the weekend onwards.
BarcelonaThe anticyclone that began to settle in over the weekend is set to last for several days. Sunshine and calm weather have prevailed in recent hours, and this situation will continue for practically the entire week. There will only be minor variations, such as some decorative touches of thin clouds and morning fog or low clouds. The morning temperature inversion will persist, as will the marked temperature contrast between day and night. Even today, the weather will be milder or warmer at midday, with some highs locally reaching around 25°C in the warmest areas of the south and the pre-coastal region, values clearly above average for this time of year. In fact, yesterday temperatures already exceeded 24°C in Aldover (Baix Ebre). On Wednesday, a maritime breeze will arrive, lowering temperatures slightly and bringing some coastal low clouds, but without any major consequences. We should look to the medium term for signs of change, but there are still many days to go and no clear end to this stable weather pattern is in sight.
Tuesday: warmer weather
Temperatures will rise slightly further on Tuesday, with mild to warm conditions in the middle of the day. Highs are expected to be between 18 and 23 °C, but could reach around 25 °C in the south of the country or in some areas of the pre-coastal region. A marked temperature inversion is expected in the morning. For example, early in the morning we find temperatures of 12 or 13 ºC in elevated areas such as the Queralt Sanctuary (Berguedà) or Montserrat, while very close by and at a much lower elevation there are -1.6 ºC in Guixers-Valls (Solsonès) or 2 ºC in Vacarisses (Vallès Occidente).
The sun will dominate, with only a few wisps of thin clouds, as well as morning fog or low clouds in plains and inland valleys, but also in some stretches of the coast, due to the contrast between the mild air and the sea water, which is still quite cold at this time of year.
Minor changes on Wednesday in a context of total calm
The influx of wetter maritime air will bring more low clouds to parts of the coast on Wednesday. This will also cause a drop in temperatures, due to the influence of the currently very cold sea water, with winter-like temperatures.
Minor variations in a context of absolute calm that will continue for much of the week. Perhaps towards the weekend, the tail end of a front will arrive, increasing cloud cover and bringing some showers to the Pyrenees. This will be brief, and it won't be until next week that instability could increase significantly. In any case, there are still many days to go, and this scenario is not yet clear. For the moment, we have a high-pressure system and calm conditions for days on end.
