Case: 04 April 2019
===============================

Summary
-------

Post-frontal open cell cumulus with minimal spacing between cells

Description
-----------

This was a post-frontal event having its frontal passage early in the event day. Although this cloud field had a cold-air outbreak type open cell cumulus set-up, the cloud field was relatively closed and connected, with small to negligible gaps between the individual cells or cell precipitation cores. The boundary layer winds were light and northerly. Cloud echo tops for the open cell periods remained near the ambient melting level (approximately 1.5 km AGL throughout the event). There was evidence of high clouds observed from SEVIRI throughout the event as associated with the previous larger scale frontal passage.
