UPDATE: I have added the 00z RAOBs from the area. If the storms can fire ahead of the linear forcing we could see another outbreak!

Here is a hodograph from our custom shear vector analysis program.

The hodograph shows a critical angel of 79deg while 90deg is perfect it has been our experience that lower then 90deg is more favorable then greater 90deg. The environment is in constant flux so this is a very hard parameter to measure but when you can get a storm close to a radar site and surface site that haven’t been overtaken by a boundary the data tends to be pretty good.
