Billings Setup

Watching as convection is getting going ahead of an embedded shortwave trough crossing the axis of the upper level ridge.  Morning 12z sounding shows quite a bit of dry air down low.

Looking at the special 18z sounding shows fairly decent inverted V setup with DCAPE nearly 1300J/kg.  Certainly a decent setup for some downburst winds this afternoon.  Winds through the mid levels are rather weak, but any collapsing cell could gain momentum and accelerate to the ground.

GOES-16 10.3 IR satellite already showing some cooling cloud tops moving into the Billings, MT CWA.  Plenty of clearing out ahead of this activity for it to continue on as it moves west.
