According to the FMI the "first snow" of the season is recorded only once there is a layer at least one centimetre deep precisely at 9 am, and that hasn't happened anywhere in Finland - at least not yet.
The snow which fell Saturday night and into Sunday morning in Lapland was evidently not enough to meet those demands.
Weather forecasts indicate that a high pressure system will hover over Finland during the new week, which will likely bring light precipitation and temperatures above the freezing point.
