This sudden Summer

Is not lasting very long. Tomorrow we can still get 22-23°C in Stockholm, and in other places in Southern to Middle Sweden perhaps 25-26°C. - but then the magic is over.

Instead we are facing rather cold weather, with temperatures below normal - which could go on for quite some time (at least a week, with MAX between 10 and 13°C). Below (second chart) is the American GFS prognosis. They differ a little bit, especially for sunday showing very low temperatures. On the other hand, showing slightly warmer weather next week - more in line with normal temperatures for the beginning of May.
