For those of you interested in using ECAPE, a link to a preprint of the paper we submitted is available here:.And a matlab script that computes this quantity is available here:.

Matlab script to load a sample sounding and compute ECAPE
Entrainment CAPE (ECAPE) is the next big thing in severe wx forecasting, imho. Brilliant work in progress by @UpdraftwMax to take a simple sounding and estimate updraft velocity with incredible accuracy. Big deal for tornado, hail potential etc.

Cuban weather radar is hinting at a developing ring of convection near the core - something that has been largely absent throughout the day

Our new theoretical study in the Journal of Atmospheric Sciences shows that because of dry air entrainment, vertical velocities in thunderstorm updrafts do not increase as quickly as CAPE.

Kilauea has erupted. Hard to find a webcam with a good vantage, but apparently fissures opened about 1 mile south of the summit caldera near the location of the intrusion earlier this year:.
