We just finished a stretch of 6 days in a row of below normal highs. With a few of those days being down right cold for mid March.
Not sure what area your quoting temps for but the models correctly forecasted a below normal period.
Now they missed on other key areas like continued burying of Energy along the west coast that hampered any possibility of seeing snow.
This has been a bias all winter for the models of underestimating the trough in the west in the long range.
