From Chi-Town Fire Photos:

I attended a Still & Box overnight at 2020 W Webster in the Bucktown neighborhood. Companies originally reported fire in the rear of this 1.5 story residence, and were interior making a good push. However, the cold wind soon took hold of the attic space and heavy fire conditions evolved. All companies were pulled out, Tower 21 was moved to Side A, and knocked the fire with their aerial master stream. Companies went back in to mop up. There is a full gallery viewable here:
