Residents of Santa Barbara have been saying that temperatures even near the fire have felt unseasonably cool.
With me to talk about that is Christine Wiedinmyer, associate director for science at the Cooperative Institute for Research in Environmental Sciences at the University of Colorado-Boulder.
