The Greenland Block is the presence of an upper air high pressure system in (you guessed it) Greenland! This disrupts the normal west to east flow and displaces the jet stream far to the south of average for the time of year. During the months from late fall to mid spring, the block creates colder than average conditions across the northeast US and deflects the storm track to the south.

Meanwhile out in the west we see the beginning of a ridge building in the west. This entire look has been nonexistent all winter along and has suddenly appeared now in March...read more at http://www.meteorologistjoecioffi.com/index.php/2017/03/08/european-weather-model-adds-to-puzzle/
