Convective Initiation over Arkansas

Looking at another example of the Convective Initiation Product over western Arkansas, from earlier this afternoon. The loop below shows the general CI product overlaid on the "sandwich" VIS/IR imagery, for the period approximately 18Z to 19Z. Looking at the cu or towering cu field over SW AR, the CI values vary considerably from one time to the next. Values are generally around 50 percent or less (green/blue), but sometimes jump up to 60-70 percent (yellow). Thunderstorms did develop over this area shortly after 21Z.  A. Cope
