The snow is there, but the temps aren't warm enough for it to runoff.
There also hasn't been a rain event like last year that spiked the flows to 60,000 CFS and made the base flow for all of February good.
I'm guessing for a snow melt peak after mid-March and giving up an early March launch.

Min temps need to stay above freezing to get a runoff.
