In a statement, the IPMA states that the cold weather is caused by an anticyclone located in northern Europe, which extends, "in a crest to the Atlantic" and "will transport a cold continental air mass to the Iberian Peninsula".

This “sharp drop in temperature values until Monday, the 23rd”, should remain “without significant changes until the end of the week” and there is no forecast of rain.

On Monday, according to the IPMA, the "minimum temperature should vary approximately between 0º and 5º C, being lower in the interior North and Center, where it will drop to values between 0 and -6º C".

The maximum temperature will also drop, “predicting values between 10º and 15ºC in most of the territory and, in the interior North and Center, values between 5º and 10ºC”.
