Pre-takeoff checklist
So I looked at the weather, and out the window.. snow showers off an on.. right at 0c on the ground.
Then I went to avwxworkshops to check the skew-t..
Ice forecast was trace-ish up to 9k, then clear above. Skew-t showed dewpoint/temp merging at 4-6k but that merger growing in a few hours when I'd be flying.
Back to the homepage, I noticed this:

Which had the description
And realize I'd be flying in these conditions... well, flying along with a cold front moving in, with those clouds moving in.
Thoughts? Did I chicken out (182RG with all the anti-ice features like defroster, and uh, pitot heat) reasonable? Would it have been fine at 9k and descend down into PKB?
That said - I've never flown in snow. At 0c ground temp, will I get ice build up from snow right after takeoff? Or would I need some other conditions to get icing in a snow shower?

During the cold season, it is quite common to find a blanket of stratocumulus clouds in the wake of a strong cold front. Stratocumulus clouds rarely have a depth of more than a few thousand feet. Even when it is cold enough for structural icing, pilots are often tempted to descend or climb through this rather “thin” layer of clouds. While some stratocumulus decks can be quite harmless even for an unprotected aircraft, they can dish out some of the most intense structural icing that can quickly overwhelm many certified ice protection systems (IPS). In this workshop, we’ll examine the icing environment for a cold stratocumulus deck that produced severe icing conditions as reported by the crew of two Boeing 767s.
