A special phase is going on in Finnish weather.

The Finnish Meteorological Institute says on its Twitter account that a strong southerly wind brings with it a warm air mass.

The warmest air mass arrives in Finland by Monday evening.

At lunch, one can even be alarmed by the November heat record.

The current record was set when on November 3, 2015, +14.3 degrees were measured in Kemiönsaari.

Foreca's meteorologist Markus Mäntykannas, on the other hand, says in his blog that the most special weather week in Finland is now going to men's memory.

- This week offers meteorological tension elements on many occasions.

The all-time heat record for November, 14.3 degrees, is under threat for the first time on Monday night and again right away on Friday, Mäntykannas says.

He explains how the storm is progressing to Finland.

- Storm low pressure will make its arrival in Finland on Monday, and already in the morning in the western sea areas and in Uusimaa the wind has been blowing in storm readings.

Strong winds supply us with very warm and humid air from the season all the way to the Mediterranean.

The latest weather models promise to break records

- In the latest weather models, the maximum temperatures on Monday evening and Tuesday night will rise to 13–14 degrees in the south-west of the country and on Åland, so the November all-time heat record for 2015 may break, Mäntykannas estimates.

During Tuesday night, the temperature, according to him, is widespread in the southern and central part of the country at over 10 degrees.

The snow in central and northern Lapland is dwindling rapidly.

The pine stock reveals in its writing that record readings can occur up to twice in the same week.

- The record hunt is on at least two occasions this week: unexpectedly, even on Friday, temperatures may rise to exceptionally high readings and 14 degrees may be exceeded more widely in the southern and central parts of the country.

However, according to him, the super-high temperatures for the rest of the week are based on a completely different mechanism than the Monday night heath.

- At the beginning of the week we receive the heat in a moist version with a strong wind all the way from the Mediterranean, but at the end of the week the heat arrives as a dry föhn wind over the Norwegian mountains.

At the moment, it seems a more likely scenario that the old November heat record would not be broken until Friday.

The previous record set in 2015 was also set as a result of the föhn wind.
