LWX: Watching for lightning…and seeing confetti

Forecaster comments from EWP blog...

We’ve started out watching the LWX CWA in the hopes of getting a feel for the DC Lightning Mapping Array.  The equipment, as well as the storms, are not cooperating however.  So, we have been monitoring the CI products in the hopes of seeing some more significant storms pop up.  The UAH CI algorithm has been treating us to a “confetti” pattern such as in the upper left on the IR image, and the lower right on the visible.  This kind of appearance is not surprising given the relative cool pool of air in place across the northeast U.S.  We have gotten a couple of minor UW CI CTC hits that developed into a couple of decent showers on the LWX 88D, which can be seen in the upper right panel. So far though, not a lot of lightning data to look at, and our domain may be shifting soon.
