GLAZIER, TX CHASE
Tim Marshall only

AMARILLO- Nice chase yesterday with that storm near Kress. Now we will try our luck again today. The vorticity max which aided yesterdays convection has lifted out of the area. There is not much in the upper air today for support except subsidence. We do have residual surface moisture with 60's dewpoints in Amarillo, however, winds are tending southwesterly, thus, we will chase home today. Moisture convergence max is best to our north so we will swing up to Canadian.
