I think the ICON is somewhat close to a longshot scenario that could bring snow to our area or the NW fringes. At day 3 there is one shortwave over CO and another over MN. If they stay longitudinally separated far enough, the more northerly wave can interfere somewhat with the maturation of the southerly wave and shunt any surface reflection further southeast. Wave amplification typically occurs when a shortwave is on the downstream side of a longwave trof.
In the ideal scenario, a 3rd follow up wave (upper Midwest at day 4) phases with the southern wave, dropping into the backside of the trof, leading to amplification and negative tilting. If we can avoid an initial wave phasing and resulting SLP into western NY, there may be enough cold air relatively close by to tap into a coastal low. We would still need the trof to take on a significant negative tilt, without pinching off the cold air source, to wrap some moisture back into the cold air.
I believe a few ensemble members have shown something like this. But the UK, EC, and GFS are pretty far off.
