CI Detection Despite Low CI Values!

The upper left image below shows a low CI probability for a developing cell in northwestern Wallowa County at 2130 UTC. The CI probability was 25%. This area did not have much middle to high clouds, so the sampling was better than other areas. Still, the CI probability was relatively low.

The image below shows the Pendleton, OR radar image of the cell increasing above 35 dBZ at 2155 UTC. This gave about 25 minutes of lead time, even though the cell had a relatively low CI probability. This shows that when the middle to high clouds are not an issue, the CI product can perform well, even with low CI probabilities. JJW
