Northwestern Oklahoma

October 3, 2002

Ernani de Lima Nascimento and I took a late afternoon trip to northwest Oklahoma today because we felt the thermodynamics (LFC fairly low) and shear (0-1 km helicity) were acceptable for possible tornadoes or, at least, supercells in northwestern Oklahoma with an ejecting shortwave trough coming out of New Mexico and Colorado. We drove northwest to Seiling, where we intercepted a new line of storms, which were not yet warned. Initiation appeared to have happened in a linear fashion.
