Next time, get some sandbags?
I found about a meter of snow on my bed one day... (it was on december 31st, actually, don't remember the year...). We were sleeping on the attic and the roof window was open just a peep (we sleep with the windows open year round, I don't mind a cold bedroom). The wind had turned to the east and had picked up, the snow was picking up too and we were downstairs celebrating the new year.
Due to that specific direction and speed of the wind, the snow had been blown underneath the window, right on top of the bed. To show the temperature of the room: the snow hadn't even melted yet
