what time will it be in the second half of august?
We have now reached exactly the middle of Augusta month that was filled with days of very hot – especially in the interior, although not as torrid as in July -, some forest fires and even with the typical days of fog in the western range, a very common meteorological phenomenon in mainland Portugal during the summer.
Despite all this, as first maps of the weather maps indicate that the second half of august – to coincide exactly with the end of the heatwave – it will be the one by one more variable weather landscape. After all, what will happen in our country, meteorologically speaking?
First harbingers of the ever-closer climatological autumn
On August 31st, the summer, from a climatological point of view, will officially end. This is a time when the atmosphere has the habit of revealing greater dynamics and thus stability usually opens the way for a wavy jet stream and with the corresponding busiest action centers: the depressions or small pockets of cold air can be through strong thunderstormsusually located, or else depressions of an atlantic character.
It is undoubtedly a height of transition, although the temperature shows summer values in most of the country (with less intensity on the North coast). Even so, how nights are usually cooler and you are already noticing the shortening of days. And for the summer 2022 epiloguewhat to expect from time in Portugal?
Rain in sight?
Concerning assignmentmany people in Portugal are waiting and eager for the arrival of rain due to the severe and extreme drought plaguing our country and a large part of Europe. This week’s depression – which will not pass directly through mainland Portugal, but only activity front associated with said pending loss center – will result in a weather state comparativelyespecially not northern mainland Portugal and a large part of the western coastal strip, between Viana do Castelo and Lisbon.
In fact, between this Monday night (15th) and Wednesday, the 17th, thunderstorms are expected, sometimes repeatedwith the electrical activity being more example in the interior and in the mountainous areas, as per region in the region of Trás-os-Montes.
A large part of the system planned for our country is planned for the west of Montejunto-Estrela. To the east of it, little will fall. Alentejo and Algarve, again, no rain in sight.
West of the Monte-Estrela system is where a large part of the drop is expected – as can be seen in the tweet above -, in a few more than 12 mm, little for the current situation of the severe drought that affects the country, but in the middle of august, any water falling from the skies is welcome.
Furthermore, as shown below in the anomaly map, the Weekly rainfall will be higher than the reference climatological average in the areas west of the Montejunto-Estrela system. To the south, it will not be anticipated that after the disturbance dissipates it will reach the Tagus basin. The Alentejo and the Algarve will continue, basically, without a “drop of rain”.
For now no generalized rain is expected for the rest of the month – in addition to the three days already mentioned and which will be confined only to certain regions bad news for the fields and basins that are very “malnourished” by the critical scenario of drought. Finally, don’t forget that sometimes the month of August can bring hail falla meteorological phenomenon greatly feared by all because of the indications that indicate that.
In the long term there are still no clear signs of the coming of showers with hailbut this possibility remains open because there are models that are “cooking” this meteorological scenario. Despite this, most numerical models, despite not predicting that they will have a concrete case at altitude, one that will probably materialize at this pernicious scenery for agricultural fields and crops.
Second half of August in Portugal: an authentic thermal zigzag?
According to our trust model, the Indicators that this week register normal or usual values across the country register that this weekdue to a abnormally cool air mass association with the depression whose front will cross the Iberian Peninsula from west to east. The temperature will be smoother, when registering a negative anomaly of -1 ºC in relation to normal.
be, this Appearing to be ephemeral since the estimates that the anticyclonic crest asserts itself again in the final stretch of August. It is predicted that the temperatures to be scaled on the thermometers, with values between 1ºC to 3ºC above normal in most of mainland Portugal (except the western Algarve and west coast – thermal values equal to or below average, more freshness).
