In the beginning of January 2026 large parts of Europe was under a cold spell and snowfall. The most extreme temperature anomalies were in Northern Finland and Sweden.
Here we will focus on the 3-day mean 2-metre temperature 8-10 January in a box over mainly northern Finland (66N-68.5N, 22E-30E)..
The plots below show analyses of z500 and T850 for the period 2 January to 11 January.
The plot below shows the 2-metre temperature anomaly for the week 5-11 January.
The plot below shows the time-series of daily mean 2-metre temperature inside the box over northern Finland for daily values (thin), 7-day running mean (thick) and climatology (dashed)).
The plot below shows the statistics for analysis and background departures for 2-metre temperature observations inside the box.
