3DVAR used over NW Missouri

Posted in Live Blogs on by Greg Stumpf.

A line with strong to severe storms continues to push rapidly to the east. The environment is favorable for rapid storm organization, given 60 kt deep layer shear and tongue of 2000 plus J/kg SBCAPE sneaking in from the SW.

2230Z: Max divergence (upper left), composite updraft max (upper right), updraft helicity (lower left) and max vorticity composite (lower right)
2237Z: Max divergence (upper left), composite updraft max (upper right), updraft helicity (lower left) and max vorticity composite (lower right)

At 2237Z, the composite reflectivity image was added (upper right) with core refl. aoa 70 dBz just where 3DVAR indeed had the most severe cell development along that line over NW Missouri.
