Missed the big show again yesterday. I am heading out west to play the upslope today while the upper trough is still hanging in to the west. Residual dewpoints were 58 at Midland and 43 at Amarillo at 9am -so significant drying in the panhandle. East-southeasterly winds at the surface would make for great turning with northwesterly upper winds. Mid-level winds are weak. Dynamics are north, moisture is south -so I am playing in between them west of Lubbock. The ellipse extends from Portales to Hobbs, NM along the border. (April 10, 1979 was an example of low CAPES high winds aloft -March 13, 1990 is a better example.)
