Very Cold Weather Situation January 2017
2017-01-20 (IPMA)
A northern flow, determined by an anticyclone that stretched from Iceland to the Canaries and a cyclone extending from Scandinavia to the Mediterranean, earlier in the week, on the 15th and 16th, carried extremely cold air from the polar region to Central and South Europe.
On the 18th January with the change of flow to the northeast the mass of cold and dry air reached Portugal mainland, originating very low values of air temperature (Figure 1a and 1b).
The central and southern regions, which are more exposed to the north-east flow, including those on the coast, recorded extremely low values of minimum temperature, which are absolute records, that is, they are now the lowest minimum temperature values ever recorded.
