Irony, thy name is weather. Especially here in South Florida, where the damn thing can turn on a dime and, historically, has been our greatest blessing, bringing tourists and settlers, and greatest curse, bringing Hurricane Andrew and its ilk. Dealing with this loaded material -- the one bit of news that always affects the viewer directly -- local cloud jockeys generally fall into one of two schools of delivery: upbeat Dr. Feelgoods or clinically precise Professor Krankenheimers. Lopicola alone, the weekend mainstay on this NBC affiliate, strikes a postmodern pose. His broad, pleasant face radiates both amusement and calm; the muscular body language -- cold fronts drawn down across the map with precise left jabs -- shows both engagement and control. This is the weather we have, for better or for worse, is his subtext -- and hey, at least we aren't shoveling snow. Lopicola's tousled brush cut makes him a "Best Hair on the Air" contender too, but his "love it or leave it" meteorology is distinctively cool.
