What windy chart modes in particular do the mods / experts think might be most useful for assessing scrub likelyhood at canaveral this afternoon?
Here's a windy-embed src link showing projected lightning strike density at 4PM EDT (0.14l/km^2)
according to ECMWF, the lightning strike data are represented in derived units of, l/km^2 or "average strikes per square kilometer per hour", interpolated/rescaled from a more course-grained primary prediction output with units of strikes/km2/day on a spatial and temporal scale of tens of kilometers & 6-hour block respectively.
A new "lightning flash density" forecast product was introduced in Cycle 45r1, released in June 2018. This can be viewed within ecCharts. The units of lightning flash density as archived are "strikes/km2/day", but these are rescaled for ecCharts usage to "average strikes/km2/h". The product is derived from HRES and ENS, with ecCharts ENS representation being probabilistic (to exceed a certain density threshold). The threshold and period duration for the probabilities are under user control.
The diagnostics aim to represent cloud-to-ground plus intra-cloud lightning strikes. Note that many ground-based lightning sensing systems are much more adept at identifying cloud-to-ground strikes.
