A quick view of the 12Z GFS from a temperature perspective shows that after the arctic front passes through here Sun/Mon, we stay continuously below freezing for high temps from Monday 2/8 until Tuesday, Feb 16. That would be a pretty significant stretch of cold spending 8 days below freezing. That's long enough to get some decent ice going on the rivers and creeks. Of course the model gives us virtually no precip after the frontal passage this Sunday through to 2/17, so suppression city seems to be the rule. It also looks like it delays the arctic frontal passage by at least 12 hours until Sunday night.
