There is a shortwave trough entering the Great Lakes region from the west.  Additionally, there is a broad jet streaming from the SW US to the upper MS valley.  At the surface, there is a cold front extending from the SW Great Lakes area SW through OK and into the southern TX PH.

There appear to be three potential plays today.  1) NE CO (DCV), 2) SW OK into the Abilene, TX area, and 3) the Southern Great Lakes area.  Area #2 has greatest potential for (large) hail, and area #3 appears to have greatest tornado potential.

Forecasters are going through their training on WDSSII as well as PAR and MRMS.  We will break at 4 pm and evaluate whethar to begin and IOP (and for which area), or to try and sneak in CASA training.  (LMA training will wait until tomorrow.)
